Patent GB-2186969-A (GB)
Title: Optical pyrometer
Inventor: ANDREWS DR ANTHONY JOHN
IPC: G01J5/08
Filed: 1986-02-21
Abstract: The operating temperature of a self-heated metal vapour laser is measured by an optical pyrometer comprising a small bore tube 7 of refractory material whose closed end contacts the laser discharge tube 2 midway along its length and whose open end projects through the thermal insulation 3 at one end of the discharge tube. A silica optical fibre 8 extends part way down the tube 7 so that its end "sees" the hot end of the tube; its other end is sealed at 9 through the vacuum casing and illuminates at 10 a PIN diode whose output is a measure of the discharge-tube temperature. The diode is preferably operated in a saturated regime to give an approximately linear output vs temperature response. <IMAGE>

Title: Dispenser e.g. for peanuts, having cartridge with rupturable closure
Inventor: MEYER JAMES BOUSEFIELD
IPC: G07F11/44
Filed: 1986-10-14
Abstract: The dispenser has a base 10, to which a disposable plastics container 12 charged with peanuts is fitted by engagement of screw threads on a wall 20 the base and a skirt 30 of the container. The base houses a coin-freed mechanism allowing a measured quantity of peanuts to be dispensed through an outlet 14 by operation of a lever 16. Prior to fitting of the container to the base, the lower end of the container is protected by a cap which is removed to expose a foil closure which is broken by knife-edges 24, 26 on the base when the container is fitted thereto. Peanuts can thus flow from the container to the base, to be dispensed through the outlet 14. <IMAGE>

Patent GB-2221438-A (GB)
Title: Emergency release system for train de-railments
Inventor: MANSER GEORGE ANTHONY
IPC: B61G7/14
Filed: 1988-06-20
Abstract: The system overcomes the problem of train carriages full of people and cargo, all becoming de-railed should a de-railment happen to one part of the train. The system scans the rail with a light sensor and uses micro switches to tell the emergency system when one of the carriages has both bogies away from the line. In this event an explosive charge or hydraulic or pneumatic device forces a piston on the connector of the train carriage to extract the connection pin from the joint connector, thus leaving the carriages separated from each other, the braking system will also disconnect then leaving the fail-safe brakes to come on and stop the free-running carriages. The piston has a slotted ramp located underneath the coupling pin head, and the latter rides up the ramp when the piston is actuated, thus withdrawing the pin from the coupling hole. <IMAGE>

Title: Microwave load cell
Inventor: FARLEY FRANCIS JAMES MACDONALD
IPC: G01L1/25
Filed: 1988-11-08
Abstract: Two modes of oscillation are excited simultaneously in a microwave resonator, the frequencies being determined by the size and shape of the resonator. The distortion of the resonator by the applied load causes the two frequencies to change in different ways. Signals from both oscillations are combined at the output, generating a beat frequency which is a measure of the applied load. Resonators of various shape are described together with the corresponding useful modes of oscillation. <IMAGE>

Title: Logic interface circuit
Inventor: GAY MICHAEL JOHN
IPC: H03K19/018
Filed: 1989-05-25
Abstract: A logic interface circuit comprises a differential amplifier 104 with two outputs 126, 128 connected to the two inputs of a logic (NAND) gate 106. The differential amplifier is arranged so that the outputs of the amplifier are at substantially different levels if an input logic signal at terminal 122 is either high or low, but are at substantially the same level when the input signal is at an intermediate level; as a result logic gate 106 produces a high output for both low and high inputs, and a low output for intermediate level inputs. A diode 138 may be connected, with either polarity, allowing the circuit to be used as an inverting or non-inverting interface. <IMAGE>

Patent GB-2223463-A (GB)
Title: Fluid suspension for a trailer
Inventor: DIXON ALAN GEOFFREY
IPC: B60G5/00
Filed: 1989-09-15
Abstract: A trailer has two axles, one behind the other adjacent the middle of the trailer, suspended from trailing link suspensions having fluid, for example air, springs 13, 14 respectively. The springs 13, 14 on each side of the trailer are connected for load equalisation by pipes 22, 23, 24 and 26, 27, 28. Levelling valve 19, supplied with pressure air from reservoir 17, is mounted on the trailer and operated by front axle movement via lever 29 and rod 31 to connect the air springs either to reservoir 17 or to atmosphere. Restrictors 33 in pipes 22, 26 throttle flow of air from springs 13 to springs 14 when the trailer is braked, attenuating the consequent nose down tendency and the downward force transfer onto the towing eye. The nose down movement may cause operation of valve 19 to admit air preferentially to springs 13 due to the restrictors 33. The rate of application of the nose down force to the towing eye is attenuated and then the force may be reduced and neutralised. <IMAGE>

Title: Conveying rod-like articles
Inventor: DYETT DEREK HENRY
IPC: A24C5/35
Filed: 1990-07-05
Abstract: In a conveying system for a stream of rod-like articles in multi-layer stack formation, in which system the stream is moved along a path which is curved in a generally horizontal plane, suction is applied to the hub of a turntable (10) for the stream, in order to draw the ends of the articles (16) against the hub and thereby help to maintain alignment of the articles during conveyance on the turntable. Further control, particularly for the uppermost articles, may be provided by a series of bristles (44) urged into contact with the articles on the turntable (10) by a guide rod (46). The system may be usefully employed in a filter cigarette assembling machine, for turning one of two streams of filter cigarettes issuing from the machine so that it may be merged with the other stream with the filter ends of the cigarettes in the two streams facing in the same direction. <IMAGE>

Title: Key assembly
Inventor: YU CHIN CHAIN
IPC: H01H13/70
Filed: 1990-07-25
Abstract: A key assembly includes a housing (2) in which a stem member (7) is slidably mounted. A coil spring (14) abuts a keytop member (11) and has a projecting portion (18), which may be in the form of an enlarged coil. The stem member (7) has a projection (10a). When the stem member (7) is forced downwardly by pressure applied to the keytop member (11), its projection (10a) engages the projecting portion (18) on the coil spring (10). Continued depression of the stern member (7) causes the spring (10) to deform, thereby providing a tactile feeling, and then the projecting portion (18) of the coil spring snaps over the projection (10) on the stem member (7) to produce a click sound. <IMAGE>

IPC: C08J9/02
Filed: 1990-10-18
Abstract: A method for producing a low-density flexible polyurethane foam comprises stirring a starting mixture containing a polyhydroxy compound, a polyisocyanate, a foaming agent and a catalyst to thereby foam the mixture, in which a foaming agent selected from water, formic acid and its salts is used in an amount of at least 5% by weight as water equivalent per 100 parts by weight of the polyhydroxy compound, and the mixture is stirred at 15 DEG C or below by previously adjusting the temperature of the mixture to 15 DEG C or below and under a highly catalytic activity. This keeps down the potentially damaging temperature reached in the interior of the material during foaming.
