Abstract: A radar system for continuously displaying target returns on a conventional television receiver. The radar includes a console connected to a rotating scanner unit through conventional slip rings. The scanner unit contains a radar antenna coupled to a receiver and transmitter, and a power supply generating a multitude of high-voltage and circuit supply voltages from AC power. A position transducer measures the rotary position of the scanner unit and triggers the transmitter as the scanner unit rotates. The return signal is thresholded to generate a video data signal, portions of which are sequentially stored in separate memory locations, each corresponding to a respective range. The set of video data in memory thus corresponds to targets within a predetermined range in a single direction.

Abstract: A solar heat roofing system including a plurality of waterproof heat absorbing panels covering substantially the entire roof of a building. The panels are formed by a pair of waterproof sheets connected to each other by elongated spacers thereby forming a plurality of fluid channels extending between the ends of the panels. A plurality of upstanding, spaced apart glazing mounts extend along the upper surfaces of the panels parallel to the spacers, and a plurality of elongated glazing supports are positioned between the glazing mounts. The glazing mounts and supports are positioned such that they follow a regular pattern when adjacent panels overlap each other. Transparent or translucent sheets are then placed in the glazing mounts with the upper surface of the glazing support contacting the underside of the sheet. The transparent or translucent sheets provide a "greenhouse effect" to increase the heat absorption of the panels, and they provide protection for the panels.

Abstract: A side scan sonar system which records return echoes in a manner which realistically displays the spatial relationship between the sonar transducer and the echo producing topographical feature on the sea floor. The system includes a dual channel strip chart recorder having a continuous transverse belt carrying a pair of equally spaced writing styli. The belt circulates at a constant speed with each stylus moving across the paper, first in one direction and then in the opposite direction. One of the styli records starboard channel data when that stylus is moving across the paper toward the right, while the other stylus records port channel data when that stylus is moving across the paper toward the left.
