Patent GB-2227309-A (GB)
Title: Detection system
Inventor: TRETT JOHN
IPC: B66B13/26
Filed: 1989-01-18
Abstract: A detection system is arranged to detect any obstruction between two sliding doors (4 and 6) of a lift cab. A transmitter (8) mounted on the leading edge of a first door (4), transmits an infra red beam to a receiver (12) mounted on the leading edge of a second door (6). A second transmitter (14) mounted on the leading edge of the other door has its input directly coupled to the output of the receiver (12) mounted on the first door (6). The second transmitter (14) produces a beam which is directed at a second receiver (10) mounted on the leading edge of the first door (4). As a result two beams are produced across the opening and any interruption of either beam will be reflected in a change in the output of the second receiver (10). The arrangement is particularly beneficial in that all the control circuitry can be mounted on the first door (4) without the need for any coupling by cable to transmitter (14) and receiver (12) on the second door (6) other than a power supply coupling.

Title: Coal analysis system
Inventor: WORMALD MALCOLM RODERIC
IPC: G01V5/00
Filed: 1989-03-14
Abstract: The system for analysing coal or other material causes the material to be bombarded with neutrons and this generates gamma rays from the material which are detected. Either two detectors of different properties are used with a single source of neutrons or two similar detectors are used with two sources of different properties. The outputs of the detectors are analyzed to generate two sets of results which are compared to determine the composition of the material. Each detector has scintillators which generate light when a gamma ray is detected, the light being detected by e.g. photomultiplies. One detector is adapted to generate an output in dependence on anticoincidence of detection events in any two scintillators of that detector, while the other detector is adapted to generate an output in dependence on coincidence of detection events in any three adjacent scintillators in that detector. <IMAGE>
