Abstract: Heat storage means are provided for reducing heat loss from a liquid crystal thermographic sheet, which normally has good heat transmission characteristics in order to respond readily to temperature variations along a body surface against which the sheet is pressed. The heat storage means include a sheet or layer of material having relatively poor thermal conductivity disposed adjacent to the thermographic sheet. One or more reflective sheets or layers may be used for reflecting the thermal image back into the layer of poor thermal conductivity.

Abstract: A television-based alarm system comprises a plurality of television cameras connected in time-multiplex mode to a set of discriminators. The discriminators are sequentially connected to receive the video signals from the cameras, the arrangement being such that each discriminator receives the video signal from a predetermined camera. Each discriminator is adapted to generate a pulse upon the occurrence of a predetermined characteristic in the picture content of the video signal corresponding to a particular type of event in the field of view of the camera. The discriminating functions of the discriminators differ so that different types of event may be detected by the various cameras. The pulses generated by the discriminator at any time connected to a camera are logically combined with a masking signal which defines a portion or portions of the field of view from which pulses are not required. A plurality of different masking signals are provided and these are provided in sequence to the discriminators.

Abstract: A pair of anchors, each with a pair of oppositely directed hooks on the end of a shank, are shiftable between flat and extended positions. In the flat position the hooks of both anchors are disposed in parallel planes so that the grapple can lie flatwise, and in extended position the pairs of hooks on one anchor are disposed in a plane perpendicular to the plane of the hooks on the other anchor so that the grapple will hang onto an object. A compressed spring drives the anchors from flat to extended positions, and a tethered trigger releases the spring.

Abstract: A method for the solidification and containment of sludge from an oil reclaiming process to permit environmentally safe storage disposal of the sludge and particularly electric transformer oil containing PCB's. In the process, the sludge or oil is mixed with fuller's earth in a weight ratio of at least 40:60 of fuller's earth to sludge or oil. The fuller's earth has a particle size not greater than -4 mesh to 0 mesh range and a moisture content of less than 12%. The mixture is allowed to harden to a paste like solid material and conveyed to a conventional land fill storage disposal site.

Abstract: An apparatus for delaying a signal n period lengths by the use of two shift registers which have capacities less than n but which have a total capacity greater than n. The signal to be delayed is fed to a first shift register until that shift register is full. The signal is then fed to a second shift register. Timing signals which control the shift registers' receipt of information are properly blanked in order to allow this result. When n bits of information have been recorded by the shift registers, the first shift register is again inputted causing an output which corresponds to the first data bits of the signal. While the first shift register is receiving and outputting the second cycle of information a pre-determined number of data bits are fed to the second shift register to fill the register. This cycle is repeated resulting in the storage of n data bits by a plurality of shift registers which each have a capacity less than n which have a total capacity greater than n.

Abstract: A solar still includes a pair of parallel dikes separated by a ditch, a first sheet overlying the ditch and pair of parallel dikes, the sheet having a pair of edges arranged substantially parallel to, and outside, the dikes, and a second sheet overlying the first sheet, the second sheet having a pair of edges bonded together with the edges of the first sheet to form a water vapor-impervious seal.A plurality of vertical columnar supports are periodically positioned in spaced relation between the first and second sheets in the center of the ditch to maintain the second sheet in spaced relation above the first sheet. The second sheet has a ridge coincident with the supports and filamentary members which connect the tops of the supports, and angularly slopes on either side thereof toward the outer edges of the dike.

Abstract: A modular getter pump includes a first and a second supporting electrode. At least one strip of high ohmic resistance material is connected to and supported by the first and second supporting electrodes. The strip of high ohmic resistance material has a length much greater than its width and only a nominal thickness and is pleated into flat substantially parallel zones which are uniformly separated from each other. The pleated strip forms a substrate having a non-evaporable getter metal at least partially embedded therein. A rod means is orthogonally positioned with respect to the width of the pleated strip for maintaining the separation between adjacent parallel zones. Such modular getter pumps can be used singularly or in a multiple array to sorb gases in closed vessels such as, for example, fusion reactors, particle accelerators, storage rings, neutral beam injectors, and others.
