A solar cell has a heat collector bar with a heat absorbing material in contact therewith. The heat absorbing material includes a transparent web member having a plurality of capsule uniformly distributed therein with each capsules having a suspension of highly reflective, flake-like, field responsive particles therein. The particles may be preoriented with respect to incident electromagnetic radiation.
A housing for an acoustic transducer includes means for dispersing internal reflections within the housing to minimize the incidence of such internally reflected acoustic pulses on the transducer itself, thereby avoiding the generation of spurious electrical signals for transmission to the translating circuitry.

Abstract:
An apparatus and a method for reducing cross talk in tape recording and playback systems is disclosed. A single magnetic track containing D data bytes of the prior art is divided into W substracks, each containing D/W data bytes. The tape recorder is capable of recording at a preselected full speed and integral fractions thereof. When recording is done at less than full speed, the W subtracks which comprise a track are offset longitudinally, such that the area covered by the W subtracks approximates the area of a single track of the prior art recorded at full speed. To further suppress cross talk, wide write heads and narrow read heads, or opposite azimuth angle heads may be used.
Material Processor With Relative Movement Between Material And Its Positioner
An elongatable endless belt passes around four rollers and, in so doing, passes adjacent to the heated surface of a U-shaped platen which has its edges adjacent to two of the rollers. The surface of the belt which faces the platen is in driving engagement with a film coming from a recording means. One of the noted two rollers is driven faster than the other so that the belt moves the film along the platen surface and leaves one edge of the latter at a higher speed than that at which the belt arrives at the other edge of the platen surface. Therefore, the belt progressively elongates and moves along the film as it is moving the latter along the platen surface.
A capstan drive motor having a integrated motor armature and driving capstan assembly with the capstan being mounted directly in one end of a rotatable center shaft of the motor with the other end of the shaft supporting an armature of the motor. The center shaft is rotatably supported on bearings positioned by adjustable mounts and with one of the bearing mounts having a cantilevered structure for temperature compensation of the shaft and bearing support system.

Abstract:
A magnetostrictive record and playback head is disclosed which utilizes an acoustic wave traveling along the surface of piezoelectric material so as to distort the surface thereof and to change the stress in a layer of magnetostrictive material along that surface at a point which depends upon the position of the traveling acoustic wave. At the point where the magnetostrictive material is changed, the material is magnetic so that a pulse in an adjacent conductor will cause a flux to form that can deposit a magnetic signal on adjacent magnetic tape.
An ultrasonic signal transducer is characterized in that the piezoelectrically active element has a first unitary electrode over the entire surface of one face and a matrix of a plurality of individual electrodes on the opposite face. In the receive mode, such an arrangement effectively constitutes a plurality of individual transducers arranged in the matrix array while maintaining the efficacy of a unitary structure. The signals from the individual electrodes are individually amplified, full-wave rectified, and combined additively to produce a composite signal which eliminates the phase cancellation of the ultrasonic pulses distributed over the face of the transducer assembly.
An improved ultrasonic transducer in which signals from portions of the transducer located a distance apart from each other are compensated for the cancellation affects due to a reflected energy striking one part before the other by use of switching circuits which pass either in-phase or out-of-phase components from the portions of the transducer to a summing circuit in such a manner that the summed output is improved.
