Title: Controlling froth concentrate level in a flotation machine
Inventor: CHUMAK FEDOR ALEXANDROVICH
IPC: B03D1/14
Filed: 1990-10-05
Abstract: The automatic control device comprises a circuit (5) used to measure the level and density of pulp in a chamber (1) in which two bubbling tubes (6, 7) are in communication with a differential pressure transducer (13) connected to means (31) for controlling the flow of frother from a tank (35) and to a correction unit (16) which is also connected to a pressure transducer (14) communicating with the tube (6). The tubes (6, 7) are disposed in hydrostatic tubes (8, 9) located outside the chamber (1) and communicating therewith at different levels relative to the pulp level. The output of the correction unit (16) is connected to a water and frother flow control circuit (21) controlling an actuator valve (23) in response to deviation of the pulp level from a preset value. A water and frother flow transducer (25) is connected to a gangue discharge rate control circuit (26) controlling an actuator valve (30) in response to deviation of the flow rate of water and frother from a preset value so that the level remain constant. <IMAGE>

Title: Timing device
Inventor: BREWER CHRISTOPHER JOHN HATHAW
IPC: G04F1/06
Filed: 1990-10-30
Abstract: A timing device (80), for particular use in a board game, in the form of a sand timer comprises a support (51) and is constructed so that movement of sand (69) between two chambers (55, 56) of the timer causes the device (80) to become unstable after a set period of time has elapsed which causes the device to topple over thus alerting an operator that the time period has elapsed. The device may also have a one-way ball valve (59, 61) which allows the device (80) to be reset at any point either during the measurement of the time period or after the time period has elapsed. In this embodiment sand flows through narrow passage 60 with the ball closing wider passage 59 but inversion allows the ball to fall against retaining bars 64, 65 and the sand to run back quickly through passage 59. <IMAGE>

Title: Nested container dispensing device
Inventor: MURRAY DAVID RIDLEY VICTOR
IPC: B65G59/10
Filed: 1991-03-08
Abstract: A beverage cup dispenser has vertical stacks of nested cups (10) arranged circumferentially around a rotatable carousel. Rotation of the carousel brings each stack in turn to a dispenser station at which circular guide rails (28), on which the lips (12) of the lowermost cups (10) rest during rotation of the carousel, are interrupted to provide vertically displaceable arcuate rail sections (30). Such displacement permits circumferentially successive lowermost cups to be dispensed, on rotation of the carousel, at the gap created between the displaced rail sections (30) and the fixed rails (28). A solenoid (32) may pivot yoke (34) about axle (36) to raise the ends of rail sections (30); alternatively these may be of flexible material which can be bent upwardly. <IMAGE>

Title: Subterranean well shifting tool for positive equalization movement
Inventor: COON ROBERT J
IPC: E21B34/14
Filed: 1991-08-27
Abstract: A subterranean well tool is provided and method of its use described wherein a shiftable sleeve (SM) covering a fluid flow communication port P may be moved from a first sealingly closed position to an intermediate pressure equalizing position without the sleeve (SM) inadvertently being shifted to a third fully open position. The tool is moved into the well until it engages the sleeve SM. The tool then shifts the sleeve downwardly to the intermediate pressure equalizing piston. Further downward movement of the tool causes its release from the sleeve so that the sleeve will remain in the equalizing position. The sleeve is moved to its fully open position by a second tool after the first tool has been removed from the well. <IMAGE>

Title: Apparatus for compensating chromatic dispersion in optical fibers
Inventor: POOLE CRAIG D
IPC: H04B10/50
Filed: 1992-09-17
Abstract: Chromatic dispersion is efficiently compensated in a compact apparatus by combining a spatial mode converter 11 with a dispersive waveguide 12 having a dispersion characteristic of substantially equivalent magnitude, and opposite sign, to the desired amount of dispersion to be compensated. The spatial mode converter exchanges the optical energy from one propagating spatial mode to another spatial mode whose propagation is supported by the waveguide 12, which may be a multimode or dual-mode fiber. This apparatus is applicable to lightwave repeaters, regenerators, transmitters, and receivers. The converter 11 and waveguide 12 may be arranged in the reverse order to that shown. <IMAGE>

Title: Anti-surge bleed valve control in a gas turbine compressor
Inventor: ROWE ARTHUR LAURENCE
IPC: F02C9/18
Filed: 1992-12-12
Abstract: A number of engine condition parameters, eg. HP compressor speed, HP compressor outlet pressure, are monitored by first and second analysers 22, 24 to detect changes outside predetermined limits. The method includes deriving a measure of heat soakage effects as an engine condition parameter by monitoring a gas flow value such as compressor outlet pressure, and deriving a further engine condition parameter by evaluating changes of engine power-setting by comparing instantaneous power-setting commands with lagged values of power-setting commands. If over-limit values of a monitored engine condition parameter are detected the bleed 14, 16 is opened and the bleed is maintained open if monitored changes of an engine operational parameter (such as compressor speed) exceed predetermined limits within a predetermined period of the opening of the bleed by an over-limit engine condition parameter. <IMAGE>

Title: Fault location in optical communications system
Inventor: HORIUCHI YUKIO
IPC: H04B17/40
Filed: 1993-05-25
Abstract: The system has optical repeaters A1, A2,... An end channels R.T for two way communication. Fault location is conducted by measuring backscatter light at an optical transmission station 1 or 2 located at the end of the optical transmission link. Each of the repeaters A1 to An includes an optical returning circuit C, C1, D, D1b, D2b for returning the backscatter light from one channel T to the other channel R. The optical returning circuit is kept conducting and gives a suitable attenuation (between 10 log n-15 and 80-10 log n dB), so that the transmission of light through the other channel R is unaffected. If a fault occurs in the optical transmission link, a measurement signal is sent from the optical transmission station 1 or 2 to one channel T, and backscatter light caused by the fault is returned by the optical returning circuit C, C1, D, D1b, D2b to the other channel; R the fault location is determined by OTDR. <IMAGE>
