Patent GB-2028222-A (GB)
Title: Waste compactors
IPC: B65B63/02
Filed: 1979-08-14
Abstract: A waste compactor provides a chamber 12 within which waste is placed with the waste being compressed against a door 19 of a closed container 11 connected to the chamber. The door 19 is then opened by lifting it vertically with rams (21) and the compressed waste pushed into the container 11 before the cycle is repeated. When the container is full, the door remains closed and the container is disconnected from the chamber and removed for emptying. The door 19 forms part of an end closure 23 of the container 11, the end closure 23 being pivotable about a horizontal axis 18 for emptying the container 11. <IMAGE>

Title: Optical fiber connector
IPC: G02B6/38
Filed: 1979-08-15
Abstract: This invention relates generally to fiber optic connectors and, more specifically, to a separable in-line fiber optic connector for coupling a pair of optical fibers or a single optical fiber and a light source or detector. The fiber optic connector 10 of the present invention includes a terminal plug member 24 having a through hole extending axially therethrough for receiving an optical fiber 20. The plug member is axially split so as to comprise first and second separate longitudinal portions defining the through hole which are transversely matable for clamping the optical fiber therebetween. A housing 30 is provided for receiving the terminal plug member 24 and confining the split portions thereof to their mating position in which they firmly clamp the optical fiber 20. At least one of the longitudinal plug portions may be transversely ribbed along at least an axial section of the through hole for engaging the optical fiber to prevent axial displacement thereof. Interengaging surfaces may be provided on the two plug portions for preventing axial displacement therebetween. <IMAGE>

Title: Device and method for fixing the end of an optical fibre
IPC: G02B6/42
Filed: 1978-08-15
Abstract: An optical fibre (14) is optically coupled to an optically active element (13), for example a light source. In order to achieve optimum coupling, the end portion of the fibre (14) is carefully adjusted in relation to said element (13) in three dimensions. The end of the fibre is provided with a sleeve (15) slidably mounted in a bushing (17). The bushing is provided with a flange (18) which is adjustably pressed against a surface (12) on a mounting base (11) which is perpendicular to the axis of the sleeve (15). The mounting base (11) also carries the optically active element (13) near the end of the fibre (14). After the sleeve (15) and the bushing (17) respectively are adjusted so that maximum coupling is obtained between the fibre and the optical element the sleeve (15), bushing (17) and mounting base (11) are fixed together by introducing a highly fluid, quick-setting glue, preferably a cyanoacrylate, between the sleeve (15) and the bushing (17) and between the bushing (17) and the mounting base (11).

Title: Starting AC Electric Motors
IPC: F04B49/06
Filed: 1979-10-31
Abstract: An asynchromous motor 1 has a run winding 5 in series with the coil 6 of a starter relay 7 having a contact 10 which controls the start winding 8, opens when the current in the winding 5 drops below a preset value and is bridged by a PTC resistor 11, which prevents arcing at contact opening and subsequently heats up to reduce the current through the winding 8. The voltage across the PTC resistor may energise the coil (14) of a delay relay (13) Fig. 2 (not shown), whose contacts (15) close to connect to the AC supply U a second similarly- controlled motor (101), whereby the motors are sequentially started to reduce the peak current demand on the supply U. <IMAGE>

Title: Desulphurizing molten metal
IPC: C21C7/064
Filed: 1980-03-27
Abstract: Desulphurizing particles of polyhedral shape and having all three spatial dimensions approximately of the same length are added to the molten metal bath by means of a lance comprising a vaporization chamber having a conical portion and a cylindrical portion. The side wall of the latter is provided with recesses and through-holes. The desulphurizing particles are preferably Mg-based and introduced using nitrogen carrier gas. The quality and extent of desulphurization so obtained are more satisfactory than are obtained with standard desulphurization methods. The favourable results are considered to depend on the synergic co- operation of desulphurizing particles having all three dimensions approximately equal and on the use of the above described lance.

Title: Rotational speed or angle sensor and evaluation circuit
IPC: G01D5/245
Filed: 1980-11-24
Abstract: The disc(s) of a sensor for detecting the rotational speed and/or instantaneous angular position of a shaft (W) has angular segments (s1, s2 etc) about its periphery. Congruent segments each comprise a tooth (1, 2 etc) and a tooth gap. A reference mark on the disc is constituted by a segment from which the tooth (10) is absent. The teeth are detected by an inductive scanner (E) and the trailing edge of each tooth produces a pulse in a coil (8) and in a micro-processor connected thereto. Each scanner pulse causes a backward counter to be reset. The counter counts pulses fed at constant frequency and the initial setting is such that the counter only counts back through zero when the toothless segment is reached. The output thereby produced by the counter is used, for example, to control the operation of an internal combustion engine ignition system. <IMAGE>

Title: Improvements relating to television sound reproduction
Inventor: SMITH COLIN
IPC: H04N5/60
Filed: 1981-08-14
Abstract: In order to provide stereo sound reproduction IF audio signals (from the television receiver) are applied to an "add-on" unit via input terminals, 1 and 2, of a 7-way socket. In addition volume control signals (VOL) and mode control signals (MC) are applied via terminals 3 and 4 respectively, and the unit is powered by the television receiver itself via the three remaining terminals, namely 5, 6 and 7. Once received, the IF signals are passed to an FM detector 10 and then to a stereo decoder 20 so as to generate stereo signals in left (A) and right (B) channels, which signals are then passed via an audio routing circuit 30 and a tone control circuit 40 to an appropriate power amplifier, one channel then being fed to a loudspeaker 60 in the unit and the other to the loudspeaker of the receiver. <IMAGE>

Title: Improved means for supporting idler rollers in conveyor systems
IPC: B65G43/02
Filed: 1982-02-17
Abstract: In a conveyor system including a plurality of idler rollers for supporting the return leg of an endless conveyor belt and extending across the full width thereof, the rollers are carried for free rotation about axle shafts having end portions projecting outwardly of the rollers and located in support means within said frame. Each axle shaft support means includes a bracket having formed therein a downwardly extending locating slot dimensioned to receive and retain the axle shaft. A reaction member extending outwardly of the frame provides a reaction surface parallel to the axle shaft for co-operation with a flat portion formed in the surface of a disc cam, eccentrically mounted on the end of the axle shaft, to resist rotation of the shaft when the shaft is engaged in the said slot. The flat portion forms a chord of the disc and is bisected by a line passing through the axis of rotation and the centre of the disc. Forced rotation of the cam by the shaft for example through seizure of the roller bearing, causes the shaft to move along said slot and to drop out of the open end thereof, whereby the roller roller moves out of contact with the conveyor belt and ceases to provide support therefor. <IMAGE>

Title: Improvements in or relating to monitoring the margin of a digital transmission system
Inventor: QUARMBY JOHN HIGH
IPC: H04L1/24
Filed: 1982-09-02
Abstract: A device 3 for monitoring the margin of a digital transmission system i.e. the capacity of the system to accommodate signal degradation, includes a data detector 4 connected in parallel with a system data detector 1. The sensitivity of detector 4 is varied by way of a D-A converter 5 which provides a signal which adjusts the detector threshold level or adds an offset to the detector input. The outputs of the two detectors are compared in exclusive-OR 8 to derive a signal indicative of the difference in the error rates of the two detectors. This signal is processed in control means 10 in such a manner as to make the error difference rate converge to a preset value which depends on the maximum acceptable error rate for satisfactory system operation. The amount by which the sensitivity of detector 4 has been adjusted is latched at 12 and provides a measure of the system margin. <IMAGE>
