Title: Method and apparatus for detecting leaking gas-filled packs
Inventor: CULLEY STEPHEN JOHN
IPC: G01M3/36
Filed: 1989-06-07
Abstract: Apparatus for testing for leaks in a gas-filled pack is placed in a packaging line and comprises two upper conveyors (10A, 10B), each connected to a load cell (12A, 12B) and positioned above a lower, synchronized conveyor (8). A gas-filled pack on the lower conveyor (8) passes under and is compressed by the first and second conveyors (10A, 10B), in succession, the pack being detected by sensors (16) connected to a control unit (6) which causes the force required to displace the pack lid to be measured by a respective load cell (12A, 12B) at regular intervals of travel. A microprocessor determines from a comparison of the two force/displacement relationships so generated whether the pack leaks. In an alternative arrangement using just one load cell, the lid of the pack is displaced by a vertically reciprocal load cell whilst the load cell is moved along the packaging line by a chain drive moved at the speed of a pack by a stepper moter. When the vertical return stroke of the load cell is completed the actuator and load cell are returned to their initial horizontal position. <IMAGE>

Title: Apparatus and method for controlling operation of storm sewage pumps
Inventor: KODATE HIDEMI
IPC: G06F19/00
Filed: 1989-06-23
Abstract: Storm sewage pumps (24) drain storm sewage in a pump well (21). In order to control the storm sewage pumps, a radar raingage (1) and ground raingages (5) are set. Measurement data from the radar raingage (1) and the ground raingages (5) are supplied to a data processing unit (2). The data processing unit (2) calibrates rainfall distribution data representing a two-dimensional rainfall distribution state obtained by the radar raingage by the measurement data from the ground raingages, and forecasts a rainfall in a predetermined time from the present from several sets of the calibrated rainfall distribution data. The data processing unit (2) performs runoff analysis corresponding to characteristics of a drainage basin on the basis of the forecasted rainfall to calculate a rainfall discharge, thereby forecasting a discharge of storm sewage flowing in the pump well. The data processing unit (2) determines the number of pumps to be operated in consideration of the discharge of storm sewage flowing in the pump well (21), a water level of a water level gauge, and the number of currently operating pumps, thereby controlling an operation of the storm sewage pumps (24).

Title: Position pick-off device
Inventor: ELLIS STAFFORD MALCOLM
IPC: G01D5/26
Filed: 1989-10-26
Abstract: A position pick-off device for use as a remote optical sensing element of an interferometer position sensing system including a first planar surface 53 possessing both light reflective and light transmissive properties disposed in parallel spaced relationship with a second planar reflective surface 55. Movement of a member whose position is being monitored causes rectilinear movement of the second planar surface with respect to the first surface in a direction A inclined at a shallow angle with respect to the planes of the first and second planar surfaces. The second planar surface is mounted on a follower part 17 constrained by a spring arrangement 15 to be capable of the required rectilinear movement only. The follower part is mounted eccentrically on an actuator pert 13 which causes the follower part to move rectilinearly when the member whose position is being monitored moves. Light reflected at the first and second planar surfaces is directed via optical fibre 71 to the interferometer system for position sensing purposes. The actuator part 13 may be moved through 60 DEG  by a radial arm 31 connected with an aircraft flight control surface operating member or an engine control member. This movement effects a change in the spacing between the reflective surface 55 and the surface 53 which is on a lens 51. <IMAGE>

Title: Automatic water flow cut-off device
Inventor: GILLIS BRIAN ROBERT
IPC: E03C1/05
Filed: 1990-08-11
Abstract: An automatic water flow cut-off device for preventing the flow of water from any item to which it is connected in the absence of any personnel includes an electric solenoid valve (C) in the water supply pipe line, which is controlled by a relay (R). The relay is switched on only when an infra-red sensor (S), suitably situated, detects the presence of a person close enough to the controlled water outlet to be actually using it. If for any reason, i.e. power cut, short term requirement, etc., a constant water supply without control should be required, a manually operated by-pass valve (B) is provided. Complete closure of the supply of water through the device and its by-pass valve is affected by closing stop-cock (A). Should removal of solenoid valve (C) be necessary, isolation valves (D) and (E) should be left closed, stop-cock (A), by-pass valve (B) opened, and water supply thus restored without fear of water loss, until replacement of solenoid valve (C) returns the device to normal function. <IMAGE>

Title: Improvements in tunnel diode circuits
IPC: G06F7/501
Filed: 1962-03-14
Abstract: 984,234. Tunnel-diode monstable circuits. NATIONAL CASH REGISTER CO. March 14, 1962 [April 17, 1961], No. 21184/63. Divided out of 984,233. Heading H3T. In a monostable circuit for performing logical operations and comprising a tunnel diode D connected in series with a load resistor R and an inductor L, in which input signals are applied via terminals A, B to the junction point of the diode and the inductor and the values of the resistor R and of the bias voltage Vc are so chosen that the diode is normally biased to a stable condition on the low-voltage portion of its characteristic, Fig. 3 (not shown), but may be excited to an unstable condition on the highvoltage portion of its characteristic by the application of positive-going clock pulses at terminal C, the input signals, however, being either of zero or negative value and the negative input signals inhibiting the action of the clock pulses so that the diode is triggered to its unstable state only when the input signals occurring simultaneously with a positive-going clock pulse are of zero value, the clock pulses are each followed after a predetermined interval by a negative-going re-set pulse, Fig. 2, this latter pulse restoring the tunnel diode, if in its unstable state, to its stable state so as to produce sharply defined pulses in the output circuit. In the circuit shown the inductor L constitutes the primary winding of an output transformer having two oppositely-poled secondary windings. It can thus be seen that if zero-level signals are given the value zero and negative signals the value unity, winding 52 delivers a conventional OR-output while winding 51 delivers the converse of this, i.e. a NOT-AND output in which a unity output occurs when both inputs are zero.

Title: Railway track occupation warning system
Inventor: PARKMAN WILLIAM TERENCE
IPC: B61L29/22
Filed: 1991-12-28
Abstract: The warning system has particular application to railway crossings with a restricted line of sight, but can be adapted e.g. for trackside working, or signalling. The system comprises a master unit (4) positioned e.g. at a crossing, or signalling point, and a slave unit (6, 7) for each directional working of the track (2) positioned a set distance from said master unit, the units being electrically connected via the track running lines (3). The master unit (4) has an operating circuit (16) for initiating, generating and transmitting a preset series of pulses to form a unique encoded message which is sent via said running lines to the slave units, and also has a receiver (26) for verifying a response from each slave unit. Each slave unit comprises a receiver (26S) for verifying an encoded message from the master unit, and a response circuit (29) for generating and transmitting its own encoded message, only if a message from the master unit is verified. In operation, if a train is either closely approaching a slave unit, or is within the section of track between a slave and the master unit, any message from the master unit will be attenuated by the train contact with the running rails sufficiently to prevent verification by its slave receiver. Preferably, the master unit (4) includes a display (23).

Patent GB-2254386-A (GB)
Title: Master cylinder
Inventor: NAKAMURA KAORU
IPC: B60T11/20
Filed: 1992-03-19
Abstract: A tandem master cylinder includes a second piston (5) which has a blind recess (6) for partially receiving a second return spring (7) in use. The blind recess (6) comprises a spring seat portion (50) which is a friction fit with the second return spring (7), a cylindrical portion (5B) having a larger diameter than the second return spring (7) and a tapered mouth portion (5A). The second return spring (7) is retained by the spring seat portion (50) so that the second return spring (7) is located coaxially with respect to the second piston (5). Although a central portion of the second return spring (7) may experience rapid lateral vibrations in use within the blind recess (6) of the second piston (5), interference with the second piston (5) is reduced to a minimum because the ends of the spring (7) are precisely axially held and because the tapered portion (5A) is provided at the open mouth of the second piston (5). Therefore, not only unpleasant noise but also small abrasions between the second piston (5) and the second return spring (7) are avoided. The master cylinder is also easier and therefore less expensive to assemble than those previously proposed. <IMAGE>
