Title: Improvements in or relating to pressure control systems

IPC: G05D16/20
Filed: 1964-10-14
Abstract: 1,065,279. Automatic pressure control. WESTLAND AIRCRAFT Ltd. Oct. 8, 1965 [Oct. 14, 1964], No. 41872/64. Heading G3R. Valve means controlling the admission or exhaustion of air to an enclosed space are automatically controlled by electronic means response to the difference between electrical signals representative of a selected pressure and the actual pressure within the space. As described, air is supplied to an aircraft cabin by a blower 64, Fig. 2 (not shown), and the pressure within the cabin is automatically controlled by a combination of five electrical signals controlling the energization of a torque motor 42 which adjusts a cabin exhaust valve 79 through a pneumatic system involving a diaphragm 75 responsive to the pressure difference between the inside and outside of the cabin. One control signal, representing cabin pressure, is obtained by rectifying the output of a moving core transformer associated with an absolute pressure bellows 20. Another control signal, representing the pressure differential between the inside and outside of the cabin, is derived in a similar manner from a differential pressure bellows 54. A third control signal, representing rate of change of cabin pressure, is derived by a resistance-capacity network 44 from the first control signal, and the fourth control signal, representing desired cabin pressure, is derived from an adjustable potentiometer 28. The fifth control signal, which is a velocity feedback signal, is derived by a resistance-capacity network 63 from a potentiometer 61 operated by exhaust valve 79. A detailed circuit involving transistor signal amplifiers, variable attenuators, limiters and a regulated supply, is described. Exhaust valve 79 is closed by operation of a bellows 82 if fall of cabin pressure is excessive, and the valve opens by virtue of a second diaphragm 83 if the pressure outside exceeds that inside sufficiently. Control of the air supply to the cabin instead of the exhaust valve and application to testing and submersible chambers are referred to.

A pipe 91, shown in longitudinal section in Fig. 5 and in transverse section in Fig. 6, passes through the lower end 81 of a material-containing hopper so that material is drawn from the hopper when air entering the pipe at one end is sucked out at the other: the pipe communicates with the interior of the hopper through a port 94 which can be closed by a valve 95. In the form shown, the valve 95 is carried by a diaphragm 96 so that it automatically closes if there is no material in the hopper when suction is applied. The invention is applied to a railroad truck having six hoppers joined in series by conduits such as 131, 132 joining the pipes 91 in the hoppers. The arrangement then ensures that, when one hopper is empty, its corresponding pipe 91 is sealed so that air does not enter it to prevent the other hoppers unloading. In the form shown in plan in Fig. 2, the hoppers are joined in two circuits 51, 54, 55 and 52, 53, 56 with trunking arranged so that suction can be applied at either of two points 110, 120 while air is admitted at a corresponding point 125, 115.

Abstract: 1277795 Digital transmission systems INTERNATIONAL BUSINESS MACHINES CORP 10 Sept 1969 [24 Sept 1968] 44600/69 Heading H4P  In a system for transferring data between a store and a number of lines which operate at different speeds and in different modes (e.g. synchronous or start-stop) each line is scanned at least once during a scan cycle. The cycle is divided into a number of segments, a number of lines being scanned sequentially during each segment. The order of scan is determined by group control words GCW. A GCW controls the sequential scanning of a group of lines having the same mode and speed. Each GCW accesses a number of line control words LCW in each of which data sent to/from the corresponding line is disassembled/assembled. At the start of a scan cycle the first GCW of a segment is read from a store address determined by a group control address register GCAR. The GCW indicates which line is to be scanned and accesses the corresponding LCW. A bit or sample is passed to/from the LCW from/to the line. Counts stored in the GCW are incremented to indicate the address of the next LCW and the next line to be scanned. Another count is decremented to indicate how many more lines are to be scanned. If the latter is not zero the next line is scanned as above, but if it is zero and the GCW does not show that it is the last of the present segment the GCAR is incremented to extract the next GCW from the store and scanning of the next group of lines proceeds as above. However, if the GCW is the last of the segment a count representing idle steps in the segment (i.e. steps in not allocated to line scanning and hence available for other machine operations) is counted to zero. If the GCAR shows that there is a further segment to be scanned it is incremented and the first GCW of the next segment is read from the store for further scanning as above. On the other hand, if there is no further segment to be scanned the whole scan cycle is now repeated. When a character to be transmitted has been assembled in the LCW it is placed in a shift register at the line's transmitter. A counter is incremented each time the line is scanned, and the count is compared with a number (from the GCW) which tells how many times the line must be scanned in each bit duration. After this number of scans the shift register content is shifted one step and the counter reset. This continues until the whole character has been read out to the line. Start and Stop bits are added if required. When the register is empty the next character from the LCW is passed to it. During reception the GCW indicates after how many steps the line must be sampled (normally mid-bit), the sample being stored in a shift register and passed to the LCW. When the register is full the character is passed to another storage area in the LCW for delivery to the store.
