Title: Electric circuit breakers
Inventor: KIDD ALAN LISTER
IPC: H01H1/54
Filed: 1984-10-23
Abstract: Upon passage of short circuit current in a circuit breaker through a conductive loop constituted by a go conductor 15 and a closely- adjacent return conductor 16 to which fixed contact 20 is connected, repulsive forces generated between the conductors 15 and 16 cause motion of the fixed contact 20 in the contact- opening direction of associated movable contact 21, which motion is limited by abutment of one end of slotted element 31 with pin 33, thereby to enhance contact pressure during short-circuit current flow prior to contact separation and ensuring rapid initial contact separation thereafter. In the absence of short circuit current, spring 34 ensures that the fixed contact 20 is retained in the illustrated rest position with the opposite end of the slotted element 31 abutting the pin 33. <IMAGE>

Filed: 1985-09-28
Abstract: A sequence control arrangement for the control of individual circuit units or "black boxes", e.g. in a production control system, or multi-processor or -memory system, sets up one step in a sequence of operations while a preceding sequence is in progress.

Patent GB-2202625-A (GB)
Title: Optical sensor
Inventor: JONES GORDON REES
IPC: G01N21/23
Filed: 1988-03-10
Abstract: An optical sensor comprises a polychromatic light source (3), a detector (4), and first and second polarisers (7) (8) disposed in the light path between the source and the detector. The polarisation axis of the first polariser (7) is substantially orthogonal to that of the second (8), and there is a modulating element (6) of birefringent material disposed therebetween. The modulating element is disposed such that a change in the parameter to be measured alters the optical path length of the polychromatic light through the modulating element, thereby changing the colour of the light incident on the detector (4). The detector comprises first and second photo-responsive elements (9) (10), the responsivity with respect to wavelength of the first element (9) being different from that of the second (10). Signals from the photo-responsive elements are fed to a microprocessor (13) which calculates the colour of the light incident on the detector as represented by two or more parameters on the Chromaticity (CIE) Diagram, and interprets this colour in terms of the parameter to be measured.

Title: Pipe freeze alarm
Inventor: FISHER SIMON PETER
IPC: G08B21/18
Filed: 1988-06-03
Abstract: A sensor is positioned in a loft space to sense the temperature of a water pipe, a water tank or the ambient atmosphere. When the sensor detects a near-freezing temperature an alarm is energized. As shown, the sensor is in the form of a bi-metallic switch BS which, when a near-freezing temperature is reached, closes to supply current from a battery B via a timer circuit T to an oscillator circuit O with causes a signalling device (e.g. a piezoelectric buzzer PZ) to emit an audible warning. The timer circuit T causes the buzzer to operate for a limited duration at periodic intervals to conserve power and prevent undue annoyance. Battery power can be tested by closing a switch SW: if the battery is in good condition, then the buzzer PZ will operate. In alternative arrangements, Figs. 1 and 2 (not shown), the sensor is in the form of a thermistor included in circuitry including a threshold level comparator. Other temperature sensors may be used. <IMAGE>

Title: Power meter
Inventor: TURNER JAMES ARTHUR
IPC: G01R21/00
Filed: 1988-06-27
Abstract: A meter for measuring electro-magnetic power available in free space, for example, in the near field of a radio frequency transmitting aerial, includes three detectors each comprising two pairs of sensors. The sensors of each pair are an electro-optic sensor (124, Figures 4,5) and a magneto-optic sensor (114, Figures 4,5) arranged in series and with their light transmission axes orthogonal to one another. The order of the sensors is reversed in one pair relative to the other pair. The three detectors are arranged so as to provide outputs dependent on the components of the Poynting vector in three orthogonal directions. The meter is thus suitable for use in free space where the field orientation is not known and is insensitive to fields other than those induced by the transmitter. <IMAGE>
