A method is provided for optimally engineering a toroidal transmission having a desired input/output ratio to implement the desired ratio of the transmission while meeting the torque and efficiency requirements of the design. Nanoparticle technology is used to manufacture the stator walls to replace the cutting and milling procedures now in use. A novel Mitchell bearing sleeve and its particular hydrodynamic lubrication and cooling method are proposed herein, as well as the introduction of a novel, ultra smooth, amorphous non-oxidizing contact sleeve material used to form the contact sleeve of the drive rollers. A novel self-lubricating system is further provided that includes an oil reservoir disposed within an output shaft of the transmission.

Toroidal transmission

The subject invention related to methods and apparatuses for the manufacture of magnetizable carrier particles. In addition the subject invention pertains to particles having one or more of a variety of particle configurations and/or functional features. These geometric particle configurations and/or functional features such as delivering or removing a pay load can be tailored to achieve one or more desired missions. The subject invention also pertains to a method and apparatus for the delivery of particles to target materials, in order to accomplish one or more of a variety of missions. In a specific embodiment of the subject invention, acicular and other particles with a lengthwise dimension that are substantially uniform and homogenous in their geometry are manufactured and provided with magnetizations. In this way, predictable mechanical force responsivity can be achieved when these particles are subjected to an external magnetic field gradient.

Method and apparatus for manufacture of magnetizable microparticles

A method of delivery of reactive substances that are attached to magnetizable needle-like particles using a magneto-mechanical delivery device. The subject method and device can be utilized for the delivery of reactive or other substances, such as DNA via the penetration of a target body. Such penetration of a target or multiple targets can initiate the interaction between the material contained within the target site and the chemical substances delivered by the particles into the targets. In a preferred embodiment, the subject device is portable and does not require electrical power.

A digital positioning system has a carrier in the form of a belt with a work surface and arrays of first and second conductors extending under that surface generally parallel to one another, each second conductor being spaced close to a first conductor to define a narrow gap between them. A voltage source applies a potential difference between the conductors to produce electrostatic fields which can attract and hold a substrate to said carrier work surface. Sensors are provided to enabling the longitudinal and lateral positions of the belt to be monitored to produce control signals to shift work elements operating on selected locations of the substrate at successive work stations to compensate for unwanted movements of the belt.

Digital precision positioning system

A device for recording an image includes a recording surface and a write head positioned next to the recording surface. The write head has at least one microtunnel, with each microtunnel having an anode placed near the recording surface and a cathode located further away from the recording surface than the anode, so as to permit generation of a gas plasma between the anode and the cathode. A voltage source varies the voltage of the anode so as to permit recording of the image on the recording surface. In another embodiment, an additional anode is located near the cathode further away from the recording surface than the first anode.

Printing device with M-tunnel write head

A printing apparatus (10) employs electrostatic gripper plates (12, 14, and 16) to stepwise advance printing substrates (18) in a reciprocating shuttle fashion past a print head (22) that contains microchannels (33) that are filled with ink by capillary action awaiting, in concave shape at each microchannel orifice, print activation which is accomplished by imposing electrical fields at each electronically addressable orifice to cause the ink to protrude in a convex shape. To cause the paper to be marked, certain orifices are activated in accordance with imagewise information that is stored digitally in a memory which feeds data for the print head to cause the ink to protrude in varying thickness dimensions from the addressed orifices in proportion to the imposed field intensities with said protruding ink positions being transferred to the printing substrate surface in step by step fashion as the substrate advances and is between each step brought momentarily in contact with the print head orifices and then withdrawn therefrom, said ink being preferably of the hot-melted type so as to accomplish instantaneous fusion of the ink when it touches the printing substrate surface and solidifies thereon, thereby causing the formation of a novel lenticular image topography.

Microchannel marking engine

An electrical motor includes a stator housing having a toroidally shaped inner cavity. A plurality of stator electromagnets are mounted along the cavity wall in a plurality of parallel helical paths. A plurality of rotor members are rotatively mounted at fixed, spaced-apart angular positions around a ring shaft whose axis is coincident with the axis of the toroidal cavity. Each rotor member includes a plurality of permanent magnets mounted around its circumference. A linear output shaft has one end connected to the ring shaft and its other end extending out of the stator housing. By properly energizing the stator electromagnets, electromagnetic fields set up by them and the rotor magnets interact to produce torque which causes the rotor members to rotate about the ring shaft and to precess laterally causing the ring shaft, and attached linear output shaft, to rotate relative to the stator housing. The toroidal configuration of the motor provides a larger volume electromagnetic field interaction space than conventional cylindrical motors which yields higher output powers and higher torques. The motor, which also has an inherent speed reduction feature, may be operated in reverse as an electrical generator.

Toroidal electrical motor/generator

Small particles are produced by supporting a pair of elongated consumable electrodes coaxially in a housing so that corresponding ends of the electrodes are spaced apart across a gap. A potential difference is applied to the electrodes so that an arc ignited in the gap between the electrode ends gasifies the electrode material at the end. The gas is then cooled so that the gas condenses into small droplets which solidify into solid particles which are collected at a collection site.

Method and apparatus for producing small particles of consistent size

A toroidal transmission includes a stator having a plurality of helical races that together define a toroidal cavity having an axis, and first and second shafts rotatable about the axis, the first shaft carrying a worm, the second shaft carrying a plurality of multiple-tooth rotors arranged in a circle about the axis so that the rotor teeth are facing toward the axis and drivingly engage the worm and the rotor teeth facing away from the axis extend into the cavity and drivingly engage the races. The transmission has a first mounting plate having an opening therein receiving the first shaft and a second mounting plate having an opening therein receiving the second shaft, the plates being positioned on opposite sides of the rotors perpendicular to the axis. The stator comprises a circular array of individual arcuate twisted ribs spaced apart about the axis, each rib having one end connected to the first plate and its other end connected to the second plate so that portions of the away-facing rotor teeth project into the spaces between the ribs, which spaces thus constitute the stator races. A method of assembling the transmission is also disclosed as are a method and apparatus for making the transmission's stator.

Toroidal transmission and method and apparatus for making and assembling

An expandable piston rotary engine includes a core having a substantially circular periphery and central axis, and a rotor/flywheel mounted concentrically for rotation relative to the core. The core defines a plurality of cylinders spaced symmetrically about, and open at, the periphery of the core. Each cylinder contains a radially expandable, substantially cylindrical piston formed of a relatively thin web of material, such as sapphire or amorphous steel. The piston web material is coiled about its associated cylinder axis, and defines an internal combustion chamber whose diameter, and volume, vary in response to a relative coiling and uncoiling of the web in its cylinder. The inner surface of the rotor/flywheel defines with the periphery of the core, the cylinders and the outer surfaces of the pistons a closed space for a hydraulic fluid. Intake and exhaust valves and fuel igniters are associated with each of the cylinders. The core and other engine components are formed of lightweight ceramic materials capable of withstanding very high operating temperatures. By driving the rotor shaft relative to the core, and changing the valving to the piston chambers, the engine may be converted for use as a compressor or fluid pump.

An electronic printing device is disclosed which uses flexible whiskers to transfer a charge corresponding to an image to a dielectric recording surface. The recording surface preferably has areas of differing conductivity so that microfields form on the dielectric surface. Ink, preferably non-charged, may then be attracted to the recording surface through dipole forces and later transferred to paper.

A toroidal drive system includes a housing composed of first and second mating housing sections having interior walls which cooperate to define a plurality of parallel, helix-like races inscribed in a torus having a circular axis. The two mating housing sections are secured together and a plurality of rotary elements are fixedly spaced apart along that axis, the elements each having an axle fixed at the axis and a plurality of removable, radially extending teeth rotatably encircling the corresponding axle, each tooth of each rotary element engaging in a different one of the plurality of races. A worm is mounted for rotation in the housing about an axis substantially perpendicular to the circular axis, that worm engaging at least one tooth of each of the plurality of rotary elements. Power take off means are connected to all of the axles and extend without the housing. Access holes are provided in the housing section walls at the bottoms of the races, the holes being larger than the teeth engaged in the races so that the housing sections can be mated around the rotary elements while the elements are missing some teeth and secured together after which the missing teeth may be installed on the rotary elements through the access holes by rotating the worm to align the missing tooth positions of the elements with the holes. Methods of making and assembling the drive system are also disclosed.

Composite materials that can be used to block radiation of a selected wavelength range or provide highly pure colors are disclosed. The materials include dispersions of metal particles that exhibit optical resonance behavior, presenting to the selected radiation absorption cross-sections that substantially exceed the particles' geometric cross-sections. The particles are preferably manufactured as uniform nanosize spheres, and dispersed evenly within a carrier material having compatible dielectric characteristics. The large absorption cross-sections ensure that a relatively small volume of particles will render the composite material fully opaque (or nearly so) to incident radiation of the resonance wavelength, blocking harmful radiation or producing highly pure colors. The durability of the particles themselves ensure resistance to mechanical wear forces and the bleaching effects of intense radiation (e.g., sunlight).
