Title: Pneumatic drive with opposed pistons - uses compressed air to retract working pistons against spring force in pressure cylinders
IPC: F15B15/08
Filed: 1975-08-12
Abstract: The pneumatic drive has a main cylinder (1) with a central pressure chamber and a piston (2) on either side. The pistons oppose each other, and are connected via a joint to a drive shaft. The piston rotate a disc (30) which has recesses (30a) for rollers (40), and is connected to a drive shaft (34) in the working chamber (3). Compressed air is supplied through an inlet (4) to the working chamber (3), the volume of which varies according to the piston positions. At each end of the main cylinder (1) is a pressure cylinder (7) with a piston spring-biased against the end of the working piston (2) push rod (11). This rod has a central bore (12) which opens (16) into the pressure cylinder (15) and into the working chamber (3). The pressure piston (7) is pushed back against the spring force by the compressed air, and air is squeezed out (35) of the cylinder. This frees the rod (11) and allows the shaft (34) and disc (30) to rotate.

Title: Electrical control system for automobile air conditioning - compares actual and set conditions to produce voltages controlling movable element and electric motor speed
IPC: B60H1/00
Filed: 1976-10-22
Abstract: The electrical control system compares first data from a measurement with second data emanating from a setting controlled by the user. The comparison of data produces a voltage W1 which, via a circuit, controls the position of a movable element. The position of the moving element is regulated by a feedback circuit (7). A voltage value equal to W1 permits, firstly, the 'all or nothing' control of at least an electrical element. Secondly production, via a circuit (13), of a voltage V which is a function of W1. The voltage V determines, via a control circuit (5), the speed of an electric motor (6). The movable element, whose position is regulated by the feedback loop (7) and whose signals are a function of W1, generates a voltage W2. This voltage W2 is equal to W1 when the regulation of the movable element has been completed.

Title: Zero adjustment on twin beam infrared analyser - using transparent detector plates with movable mirrors beneath
IPC: G01N21/37
Filed: 1977-08-31
Abstract: Zero setting on non-dispersive infra-red gas analysers uses a two beam process with double chamber receivers. The beam emitted by the radiation source passes through two gas layers separated by a partition transparent to infra-red radiation. The back wall of the cell is also transparent and located behind this is a mechanically adjustable method for reflecting part of the transmitted radiation into the second gas layer. A plate with a reflective surface is mounted parallel to the rear wall in either the measuring or comparison sections. It can be so located that it partially reflects radiation into either section. Used for IR gas analysis. Because of problems in obtaining absolute symmetry between two sections on the twin beam system, setting the zero can be a problem. The device described gives a method for zero signal adjustment.

Title: Road vehicle speed limiting device - has generator supplying voltage proportional to engine speed to control circuit
IPC: F02D9/02
Filed: 1977-09-06
Abstract: The maximum speed of a road vehicle is limited by a device which shuts off the air and fuel supply when the chosen maximum speed is reached. A generator (5h) driven from the engine supplies a voltage (Ve) proportional to engine speed through a rectifier (6). The voltage (Ve) is for to a comparator (7) which compares it with a fixed voltage (V2). If the voltage (Ve) exceeds (V2) a signal (Vv) is transmitted to a relay (8) which energises a solenoid (9). The solenoid (9) closes the engine throttle (1) by means of the connecting cable and so shuts off the supply of air and fuel.
