Abstract: ABSTRACT OF THE DISCLOSURE   Cooling apparatus and method for an electric cable installation in which the cable has a plurality of oil filled channels, the movement of the oil cooling the cable.  The apparatus differs from prior art apparatus in that it uses a pair of multi-cylinder pumps, one at each end of the cable channels and having a number of oil operable cylinders equal to the number of channels, and a number of combination tanks at each end of the channels equal to the number of channels, each tank including an oil operable, bellows-type separator and the tanks and pump cylinders being connected so that the circuit for the cable oil is separate from the circuit for the actuating oil of the cylinders and from the fluid which opposes movement of the separator. Electrovalves at each end of the channels control the insulating oil flow between the channels and the tanks, and the opening and closing of the electro-valves and the operation of the pumps is coordinated so that cooling oil in the channels oscillates and moves simultaneously in the same direction when enforced or higher cooling is required.  When the pumps and electrovalves are de-energized (electrovalves open), the system operates in a conventional manner to compensate for cooling oil expansion and contraction with normal, e.g., ambient and normal load, temperature changes.

Abstract: Abstract of the Disclosure A non-duplicative switching arrangement for controlling a video or radio frequency switch is used in a cable television system for controlling the application of a distant station signal to the cable system to eliminate duplication in programming. A clock provides an output indicative of the day and time while a timing means, responsive to the output of the clock provides timing signals.  Switching is programmed on a transparent matrix disc which has a plurality of concentric circular rows of matrix positions.  Each row corresponds to a day of the week and the matrix positions are aligned radially with respect to the disc in columns which correspond to daily time segments.  The light transmitting characteristics of selected ones of the matrix positions are altered impermanently in order to program the switching arrangement.  A stepping motor is provided for rotating the disc at predetermined times and an optical reader determines the light transmitting characteristics at each successive matrix position.   A motor is provided for actuating the switch into one of its switching states in dependence upon the output from the optical reader.  Additional switches may be controlled by providing slave switching control units.  Each slave unit is substantially the same as the first control unit with the exception that the slave units rely upon the clock and timing means of the first unit.

Abstract: Disclosed herein is a ring laser gyroscope whose output photodetector assembly is a laminated structure having three electrically mutually isolate photodiodes on a common substrate, located directly behind a multilayer dielectriccoated, partially light-transmissive mirror that is one of the reflective elements of the ring laser.  A small proportion of light energy of the beams incident on the mirror is allowed to pass through the mirror and strikes the photodiodes.  Two of the diodes are masked in such a manner that they generate a heterodyne beat signal which represents lateral displacement of the interference fringe pattern set up in the area of intersection of the two oppositely directed beams in the ring laser. The resulting output signal is used to determined the rate of rotation of the ring laser body.  The third diode sums the light intensity of the fringe pattern and generates an output signal which, in a feedback arrangement, is applied to a cavity length control circuit.
