Title: Temperature regulation by means of proportional pulses - uses two operational amplifiers, with two feedback circuits and bridge network
IPC: G05B11/28
Filed: 1975-10-21
Abstract: The temperature regulator can be used on most heating systems. It transforms the heat regulator into a proportional regulator. This being obtained by means of pulses. The pulses and the distance between pulses being determined by a simple analyser digital computer. The regulator is composed of two operational circuits. The first circuit (1) receives data from a measuring bridge. The bridge consists of a negative temperature resistance (2), a fixed or variable resistance (3) and a potentiometer (4). The gain of the first amplifier determines the temperature difference necessary for a variation from minimum to maximum of the pulse durations or the gap between pulses. The second operational amplifier (5) is connected so that it forms a peak signal generator driven by the variable voltage delivered by the first amplifier. This result is achieved by two feedback circuits, one delayed and the other non-delayed.

Title: Drying accumulator and battery electrodes - prevents deterioration over relatively long periods without storage in a liquid
IPC: H01M4/23
Filed: 1975-11-18
Abstract: Charged electrodes are dried by immersion in a liq. which is immiscible with water, and which is raised to a temp. >100 degrees C but below its distn. point. The water retained in the interstices of the electrodes evaporates and is replaced by the liq., which is recovered by treating the electrodes with a hot, pressurised, inert gas. Reduces the failure rate of stored electrodes, over periods up to two years, to 1%. The method allows a thin protective layer to be deposited. After their electroformation and before they are dried, the electrodes are kept in a bath of water.

Title: Door for use on house - has hinge housing hung for right or left hand operation
Inventor: CASTRUP ROLF
IPC: E06B3/70
Filed: 1976-03-19
Abstract: The door for use on houses can be left-or right-hand opening and comprises a panel with housings for the hinges. These housings are symmetrical in relation to the vertical axis of the front face. Because of the symmetrical structure of the hinge housings, it is possible to fix the hinges on the front face, symmetrically in relation to its vertical axis, both for right- and left-hand opening. Therefore, if the opening side of the door has to be changed, the door only has to be turned through 180 deg. around the vertical axis and it can then be hung after the hinges have been removed and replaced.

Title: Photographic system photoelectric transducer - uses integrated circuits for automatic exposure control of camera according to ambient light
Inventor: HOSOE KAZUYA
IPC: H01L31/0203
Filed: 1977-03-10
Abstract: The photographic system photoelectric transducer has an opaque housing with a window formed in one of its sides. One or several mutually insulated photoelectric transducer elements are arranged in the housing so as to receive light entering through the window. A circuit processes the output or outputs of the transducer (13) or transducers. This circuit produces an output signal which represents the degree of cleanness of an image of an object or the luminosity of the object. The circuit is an integrated circuit and is positioned in the housing in a sealed and screened fashion. When the number of transducer elements is not equal to one the circuit has a sequential signal system. This sequential signal system receives the outputs of the photoelectric transducers to produce a succession of outputs in time relationship.
