This invention is advantageous in irradiating pallets which cannot be irradiated by conventional techniques, even by x-rays, throughout their complete volumes. In one embodiment, a scan horn scans electron beamlets through a sweep angle. A dipole bends the electron beamlets to focus the electron beamlets at the pallet center. After being bent, the beam becomes converted to x-rays which are irradiated through the pallet to the pallet center. During this irradiation, the pallet is moved in a direction substantially perpendicular to the irradiation. In this way, a quarter of the pallet is irradiated. When the quadrant radiation is completed, the radiation is interrupted and the pallet is rotated 90&#xb0; to have a second side of the pallet face the radiation. The operation is sequentially repeated for each of the pallet sides. The four (4) irradiated quadrants define the pallet's complete cross-sectional area.

X-ray pallet processing

An accelerator directs an electron beam to a scanner which operates under microprocessor control to convert the beam into two (2) sets of spaced electron beamlets. A magnetic lens deflects the sets of beamlets to a spaced and substantially parallel relationship. A first dipole directs the first set of beamlets in a first direction to a first side of an article. A second dipole directs the second set of beamlets, in a second direction opposite to the first direction, to a second side of the article opposite to the first side of the article. In this way, a single accelerator irradiates two (2) opposite sides of the article with an enhanced precision, simplified controls, a significantly reduced number of components and reduced costs relative to the systems of the prior art. The electron beam may be converted to an x-ray beam which is then processed in the manner described above.

A method and apparatus for understanding and predicting customer behavior called the Strategic Profiler is disclosed. In the Strategic Profiler, multiple participants input data representing ideals, reality, and experiences. The data are collected and analyzed using a multiple factor personality model to determine key value drivers, with one value driver associated with each factor in the multiple factor personality model employed. The data are further analyzed to determine the participants' impression of how closely reality meets the ideal, based both on impressions and experience. In a preferred embodiment, the Strategic Profiler is available to multiple users simultaneously through the World Wide Web.

A recombinant lead acid battery is provided having positive and negative plates coated with active material and separated by a compressible separator material containing an electrolyte. A casing provides structural support for the plates and encases the battery's components. The battery is preferably a recombinant lead acid battery with its plates being formed of lead foil sheets. The casing is reinforced and arranged to i) maintain a substantially evenly distributed compressive force on the separator material and ii) maintain a constant spacing between the plates. The battery is arranged to maintain a compressive force of at least eight psi on the plates which has been found to significantly reduce the incidence of premature capacity loss (PCL). By way of example, compressive forces in the range of 8-14 psi work well for conventional separator materials. In one embodiment, the casing includes a plurality of reinforcing support pins extending between upper and lower casing members through the plates and separator material for maintaining the evenly distributed pressure. Plates may be slacked one above another to provide a plurality of cells. A method of making the battery is also described.

An electron beam is generated in a packetized form defined by pulses having a duty cycle of less than 1:1000. Each pulse may have a width of approximately one microsecond (1 .mu.sec.) and may be separated by approximately one (1) second from the next pulse. The electrical beam may be accelerated, preferably linearly. The electrical beam may be modulated at a particular frequency (e.g. 3 gigahertz) by bunching the electrons during the beam acceleration. The electrons may be converted to photons (e.g. X-rays) by directing the electron beam to a target made from a suitable material (e.g. tungsten). The photons are then interacted with the electrical circuitry to produce photoelectrons. The photoelectrons impair the operation of the electronic circuitry by generating an electrical current in the electrical circuitry, generating capacitive charges in the circuitry and generating an electromagnetic field in the vicinity of the circuitry. The electrical circuitry may be disposed within an enclosure substantially impervious to the penetration of external electromagnetic fields, but passing energetic photons (x-rays). The enclosure may resonate at the modulating frequency. This invention is primarily intended to be used for experimental purposes to determine how the electrical circuitry may be protected to prevent the electrical circuitry from being operationally impaired by photons passing to the electrical circuitry.

Modulated radiation pulse concept for impairing electrical circuitry

An interstitial X-ray needle includes an elongated X-ray tube coupled to an electron emitter at one end of the tube, with a converter element being disposed at a tip of the other end of the tube for converting emitted electrons into X-ray; a solenoid coil wound around the tube for providing a magnetic field that confines the emitted electrons within a narrow beam; an elongated outer casing enclosing the tube and coil; and a pipe coaxially disposed between the casing and the tube for defining an inner annular flow chamber between the tip of the tube and a coolant inlet in the casing and an outer annular flow chamber between the tip of the tube and a coolant outlet in the casing.

Interstitial X-ray needle

An electron gun emits a steady stream of electrons. The electrons pass to a modulating cavity which accelerates some of the electrons and decelerates other electrons in a particular timed relationship so that the electrons become periodically bunched. The bunched electrons are then accelerated in an accelerator to a constant speed such as the speed of light to maintain the bunching of the electrons and to substantially increase the energy of the electrons. The kinetic energy in the bunches of electrons is then converted to microwave energy. The conversion may occur in one output cavity or in a series of output cavities. Apparatus such as described above may be connected in parallel to further increase the output microwave energy.

High efficiency high power microwave source

A beam of energy in a first form, such as electrons, is provided in a first direction. The beam may be pulsed or continuous. The beam is intercepted by a member, such as a converter target, to produce energy in a second form such as x-rays. The converter target may be formed from a heavy material such as tungsten or tantalum. The interaction of the electron beam with the converter target will produce energetic bremsstrahlung x-rays in an energy range including 10.6 Mev to approximately 13.0 Mev. This range is sufficient to excite the abundant nitrogen atoms in common explosives to induce the production of annihilation photons but is not sufficient to substantially excite atom of the most abundant elements of the earth's crust (e.g. oxygen, silicon, iron, aluminum, carbon, hydrogen, etc.), which comprise most common fabricated articles and soils. The converter target is disposed relative to an object (e.g. a suitcase in an airport) to obtain the production of energy in a third form, such as photons, from the object. The photons pass to a detector such as a scintillation counter which determines the concentration of the nitrogen in the object. The detector may be gated so as to be activated only when the photons are passing from the object to the detector. When the object is a suitcase which is moved along a conveyor, the detector may be downstream from the source in the direction of movement of the conveyor.

Presented is an auxiliary rolled toilet tissue holder and storage device constructed as a separate unitary structure for mounting on the conventional lugs found on the conventional recessed rolled toilet tissue receptacle. The device provides a housing portion within which a recess is provided to receive the extra roll of toilet tissue. From the housing project mounting arms that pivotally lock into the conventional rolled toilet tissue receptacle lugs. The extra roll of toilet tissue is accessible by merely pivoting the housing away from the wall, permitting the extra roll to fall into one's hand.

A self-contained hermetically sealed foil changer for advancing a portion of foil web into a position normal to the path of a high energy particle beam. The path of the beam is defined generally by an aperture plate and cooperating axially movable barrel such that the barrel can be advanced toward the plate thereby positioning a portion of the foil across the beam path and sealing the foil between the barrel and the plate to form a membrane across said beam path. A spooling apparatus contained in the foil changer permits selectively advancing a fresh supply of foil across the beam path without breaking the foil changer seal.

An autogenerating apparatus provides secondary intense relativistic current beam pulses in response to an injected beam pulse. One or more electromagnetic energy storage devices are provided in conjunction with gaps along a beam propagation path for the injected beam pulse. For injected beam pulses which are no longer than double the transit time of electromagnetic waves within the storage devices (which may be resonant cavities), distinct secondary beam pulses are generated by each of the energy storage devices. The beam propagation path, together with the one or more gaps provided therein, operates as a pulse forming transmission line cavity, in which the separate cavities associated with the gaps provide delays for electromagnetic waves generated at the gaps. After doubly traversing the cavity, the electromagnetic waves cause the gap to generate the secondary beam pulses, which are thus delayed by a time interval equal to the double transit time for the induced wave within the cavity.

A method and apparatus for permanently and sealably connecting two duct sections, the duct sections having peripheral flanges forming opposite and corresponding halves of a composite, T-shaped peripheral flange extending outwardly from the duct sections. The composite flange has an upper cross-piece portion and a lower upright portion, the lower upright portion of the T-shaped flange containing a continuous reservoir of deformable gasket material. The method comprises the steps of first placing square-cornered, U-shaped clamps over the upper cross-piece portion of the T-shaped flange at spaced intervals thereon; secondly, pressing sides of each of the clamps inwardly and crimping the clamps to upper and lower surfaces of the upper cross-piece portion, forcing a portion of the gasket material to flow from the reservoir between the flange halves, towards the duct sections, thereby producing a sealed joint between the duct sections; and thirdly, rippling each of the clamps simultaneously with the upper cross-piece portion adjacent each of the clamps, causing undulations in both which prevent the clamps from slipping out of clamping contact with the upper portion of the T-shaped flange, thereby permanently connecting the duct sections.

High pressure duct clamp and method of use

The acceleration of large numbers of ions to high energies uses an intense relativistic electron beam produced by a vacuum diode. An electron beam radial profile is maintained by a strong longitudinal magnetic field. A virtual cathode, characterized by an electrostatic potential depression whose depth corresponds to the injected electron beam kinetic energy will form. The virtual cathode is caused to move backwards toward the vacuum diode by utilizing the time history of the injected electron beam voltage and current, and by appropriately flaring the drift tube. Ions trapped in the potential well associated with the virtual cathode move with the virtual cathode and are synchronously accelerated.
