A drinking cup has sandwiched between an inner paper liner and an outer paper shell a ridge structure which has its ridges running peripherally, i.e. perpendicular to the axis, e.g. in the form of corrugations, a mesh or a cell network and can be partially filled with a phase-transition material to maintain a maximum temperature at the exterior of the shell for a given hot temperature of the liquid within the cup.

Chemical reaction is effected utilizing light of an appropriate frequency supplied preferably via optical fibers to one or more light extractors having light-emissive surfaces in contact with reactants. The light can be concentrated before being delivered. Wave guides and a plurality of such extractors can be provided within the vessel.

Method of and apparatus for optically enhancing chemical reactions

A space at least partly enclosed by an appliance housing can be illuminated by utilizing at least one lamp outside that space and coupling a light pipe system to that lamp so that light can be conducted into the space by a light-transmission system. Within the space light is emitted from one or more light extractors optically coupled to the light-transmission system. The light extractors are in the form of wave guides provided along a surface with formations or the like from which light is emitted.

Remote illumination and light apportionment in appliances

A compound parabolic concentrator which can be used as an optical connector or in a like management system or simply as a concentrator or even as a spotlight, has a hollow body formed with an input aperture and an output aperture and a wall connecting the input aperture with the output aperture and diverting from the smaller of the cross sectional areas to the larger cross sectional areas of the apertures. The wall is composed of contiguous elongated prisms of a transparent dielectric material so that the single reflection from the inlet aperture to the outlet aperture takes place within the prisms and thus the losses of purely reflective reflectors can be avoided.

High efficiency compound parabolic concentrators and optical fiber

A luminaire which has in its housing a multiplicity of groups of light emitters of different colors or pluralities of optical waveguides constructed to emit light progressively along the lengths thereof and a diffuser at which the colors can be mixed and from which the light emerges. The emitters can be controlled at the housing or light can be delivered to the optical waveguides by optical fibers from remote light sources.

A reflector has a body of a ceramic oxide superconductive material whose surface is treated to be diffusively reflective and is coated with diamond-like carbon or magnesium fluoride.

Nonspecular reflector with diffusely reflecting superconductor and

A method of making a composite high-temperature superconducting wire in which a layer of a superconductive oxide is coated onto a refractory core by melting a zone of the layer uniformly all around the core as the core is drawn through the focus of a reflector having the shape of a paraboloid of revolution while directing onto the reflector a collimated beam of an energy sufficient to melt the layer. The melted layer is cooled with a substantially radially symmetrical thermal gradient to form the superconducting oxide ceramic layer on the core with radially-directed growth of columnar grains of the superconducting oxide ceramic.

A high efficiency integrating sphere that can be used in a large variety of scientific instruments. The sphere having an efficiency gain obtained by using a superconducting material, acting as a perfect reflector, on the inside hollow surface of the sphere. The sphere is operated with a delay between the incident and sensed light, heretofore not possible, and yielding substantial improvement in the signal-to noise ratio of the integrating sphere.

A reactor capable of continuously producing activated species of oxygen molecules, specifically those known in the prior art as 'Delta Singlet Oxygen'. Uses of 'Delta Singlet Oxygen' include the maintenance of high oxidation potential during the deposition of layers of high temperature superconductors. Such species are particularly effective in obtaining ultra smooth surfaces when used as the etching gas in plasma milling of a diamond-like carbon film. The use of a film of this type has been found to be the ideal insulating barrier for construction of high temperature superconducting Josephson junctions. The reactor uses toroidal pipes to generate mutual impingement between a reaction machine and chlorine gas.

A light system comprising a light source adapted to illuminate an area and at least two refracting substantially transparent and coextensive films juxtaposed with one another and interposed between the source and the area, the films having mutually confronting patterns of refracting rises formed on respective surfaces of the films, the rises being separated by intervening recesses and the rises and recesses being so oriented as to form diversely distributed light-refraction paths across the films, the patterns being selected so that gaps are provided between the films and to effect diffusion of light from the source cast upon the area.

Lightweight low-loss refractive light diffusion system

Thermoelectric heat pumps using recuperative heat exchange are described. These devices use sets of thermocouples (thermoelectric couples) arranged side-by-side to form a plate. The plate is positioned in a fluid-containing vessel and heat exchanging fluid is flowed down one side of the plate and up the other side. In these devices the heat flow, and thus the driving thermal gradient on each thermoelectric couple in the device, is in a direction from one side of the plate to the other side, i.e., other than the direction of the device's working thermal gradient, which is the direction of the flow of fluid. Generally these two directions (driving gradient on the thermoelectric couples and fluid flow-working thermal gradient) are essentially orthogonal to each other.

Thermoelectric device with recuperative heat exchangers

A thermoelectric device has a cylindrical structure with a hollow central annulus member in which a fluid is pumped so that the heated fluid is pumped from the center of the structure and discharged on the outer surface of an outer annulus member or with the reversal of electrical current, the heated fluid is pumped from the outer periphery and discharged in the central tube. A plurality of thermoelectric cells are positioned in the space between the inner and outer annulus members with the cells being radially directed relative to the axis of the inner annulus member. A thermoelectric device having a similar structure may be used for the conversion of thermal energy to electrical energy when a thermal gradient is imposed between the inner member of the structure and the peripheral surface.

Cylindrical thermoelectric cells

Temporal and spatial modulation of magnetic fields created around solenoids and within their hollow is effected using specially configured and movable superconducting elements as well as switchable superconducting elements.

Modulation of magnetic fields formed by solenoids

A controlled emission of light from an optical waveguide, e.g. a fiber into which light is injected at one end, is effected by modifying the periphery of the waveguide over a generally triangular zone so that there is a controlled emission per unit length at every point along this zone and light emanates continuously over the length of the zone from the fiber.
