Patent GB-2014199-A (GB)
Title: Spool Axminster looms
IPC: D03D39/04
Filed: 1979-02-21
Abstract: A method of reducing pile yarn waste on spool Axminster looms comprises measuring a characteristic of the spool before or after each dipping operation, comparing the measurement obtained with a predetermined required measurement and altering the braking pressure on the spool which controls the amount of yarn drawn off the spool in each dipping operation in accordance with the variation from the required measurement. In a particular arrangement, the length of yarn projecting from the spool is measured prior to a dipping operation by means of fibre optic device and this measurement is fed to a microprocessor which automatically compares it to the predetermined measurement, feeds appropriate information to the braking system of the spool and alters the braking pressure accordingly.

Patent GB-2048525-A (GB)
Title: Timed control circuit for electric heater
IPC: G05D23/24
Filed: 1979-04-11
Abstract: The charging time of an off-peak electric storage heater controlled by a timing circuit, is modified automatically in accordance with ambient temperature. When a linearly changing current IT produced by a ramp generator A, equals a current value IS determined by a manually settable potentiometer 13, an amplifier 12 output changes state causing the heater to be switched ON via a transistor and relay switch. This will occur at a time dependent upon the setting of 13 assuming that a current IC1 equals a current IC2 of the amplifier input line 15. IC1 = IC2 when the ambient temperature detected by a sensor 14 equals a datum temperature eg 20 DEG C. Any temperature deviation results in inequality. Consequently for a fixed value of IS, a different value of IT will be required to balance the currents in line 15; the time taken to reach balance will change, providing more or less charging time for the heater depending upon whether the ambient temperature is less or greater than 20 DEG C. <IMAGE>

Title: Non polarizing electrode system for geophysical prospecting systems
IPC: G01V3/24
Filed: 1979-08-06
Abstract: In electrical geophysical prospecting and in well-logging, in which potential is applied to the earth to cause direct current (or low frequency alternating current) to flow between spaced electrodes and the potential is measured between other electrodes contacting the earth, difficulties are experienced due to the electrode chemistry at the electrode contacts with the earth. This phenomenon is usually called polarization, with spontaneous, usually varying potential being generated at the electrode contact. The present apparatus uses four pairs 41, 42, 43, 44 of relatively closely spaced solid conductor electrodes instead of the individual electrodes formerly used, and an alternating voltage from source 54 is applied via transformers 49, 50, 51, 52 between the two electrodes of each pair which minimizes polarization. A direct or low frequency A.C. potential 60 is coupled between pairs 41, 42 to provide a measuring current to the earth 40 and the resultant potential is measured between the pairs 43, 44 of the electrodes in contact with the earth 40. The alternating bias current is at least of the order of magnitude and preferably somewhat greater than the direct current in an electrode. <IMAGE>

A metal interlay is preferably provided between the mouldings. <IMAGE>
Patent GB-2066364-A (GB)
Title: Actuator
IPC: B63H25/28
Filed: 1979-08-30
Abstract: A pressurised fluid linear or semi- rotary actuator 4c, 4d, 4e or 4f is provided with a free-floating piston P or vane which separates two distinct pressurised fluid supply lines opening into the actuator working chamber. In the piston and cylinder actuator shown, pressure in both the supply lines causes the free piston P to occupy a central position, but if one of the supply lines fails, the free piston P moves into contact either with the closed end of the cylinder or with the working piston 3, whereupon the actuator continues to function with a single source of pressurised fluid. The four actuators 4c, 4d, 4e, and 4f are disposed in opposed pairs to turn a tiller arm 2 of a ship's steering gear when a diametrically opposite pair is pressurised and the other diametrically opposite pair is allowed to exhaust. Separate hydraulic circuits connect two pumps 5a, 5b to respective opposite sides of the free piston P of each actuator. Braking systems employing actuators of the piston-and-cylinder type are also described. <IMAGE>

Patent GB-2038920-A (GB)
Title: Interlocking Container Doors
IPC: G21F5/12
Filed: 1979-11-01
Abstract: A container 11 is releasably held against a transfer port of an enclosure 2 by a slidable locking member 10 engaging behind lug 11. A pin 17 passing through the wall of the enclosure prevents movement of the locking member 10 when the port cover 8 has been removed and prevents removal of the port cover 8 when the locking member 10 is not in its container-locking position. Cover 8 is released by rotation and bears a co- rotatable disc 16 having recess 18. In the port fastening position pin 17 prevents rotation being held in recess 18 by wing 24 on locking fork 10. When the fork 10 is in the container holding position a recess 31 can accept pin 17 which is carried into it by turning cover 8. Pin 17 then holds fork 10 in its fastening position. On closing cover 8, the reverse occurs and fork 10 may be moved to release container 1. <IMAGE>

Patent GB-801517-A (GB)
Abstract: 801,517. Transformers. FARRAND OPTICAL CO., Inc. May 7, 1956 [Sept. 26, 1955], No. 14089/56. Class 38 (2). A transformer of variable coupling factor comprises two relatively rotatable winding supports 12, 14, a winding on at least one of the supports being in the form of two spirals disposed coaxially and connected in series at radially similarly positioned ends. As shown in Fig. 1, the two spirals 23, 25, formed by photo etching silver on glass discs 12, 14, are connected at the axis 24. In another embodiment (Fig. 2, not shown) two such windings are disposed on the disc at 90 degrees to one another. In a transformer comprising two Fig. 1 discs the coupling varies cyclically on relative rotation of the discs through 360 degrees. The combination of a Fig. 1 disc and a Fig. 2 disc provides a " resolver," i.e. the coupling is such that on application of a sinusoidal voltage to the Fig. 1 winding the output in the two Fig. 2 windings have amplitudes which vary as the sine and cosine of the angle between the discs. A Fig. 1 or Fig. 2 disc may be combined with a disc as shown in Fig. 3 where the winding comprises circular arcuate segments 51-56 extending through a sector of 120 degrees and by so doing minimizing the third harmonic in the coupling wave. A second sector 69 is also provided to minimize effects to wobble of the discs and misplacement of the patterns. In a further embodiment (Fig. 4, not shown) several sectors are provided on a disc and connected into two windings in space quadrature. The ratio of spiral width to spacing may be chosen to eliminate harmonic effects in a manner similar to that described in Specification 801,516, and the arcuate segments 51-56 may be spiral arcs and not circular arcs.

Title: Relubrication device for shaft bearings
IPC: F16C33/66
Filed: 1980-05-09
Abstract: The relubrication device comprises a reservoir (15) containing lubricant e.g. grease (16) positioned in thermal contact with the bearing so that when the temperature of the bearing (12) increases as a result of the consumption of the bearing lubricant additional lubricant is forced out of the reservoir and into the race of the bearing. The (or each of several) reservoir may be caused to decrease in size by being formed of a material which shrinks on heating or by including a bimetallic strip, or may contain a thermally activated propellant mixed with the lubricant or acting on a plate contacting it. Alternatively a bimetallic strip may compress an oil-impregnated felt pad in the reservoir. The reservoir may be of toroidal form. <IMAGE>
