Patent GB-2024361-A (GB)
Title: Linkage tensioner
IPC: F16H19/02
Filed: 1979-06-11
Abstract: A linkage tensioner 25 comprises a rigid body 26, 55 bearing a pair of deflector members 36, 39; 62, 63 which establish a bent path along the body. A stiffly bendable elongate rod 40, 65 extends along the bent path. The rod and the body are connected into a linkage 22 so as to form a part of the linkage. When a tensile force above a datum value is applied to the tensioner 25 the rod is pulled along the bent path, being bent as it moves, and this elongates the tensioner until the tensile force in the linkage is relieved to a datum value, thereby establishing the tension in the linkage at the datum value. <IMAGE>
Patent GB-2027242-A (GB)
Title: Improvements in or relating to alarm systems
IPC: G08B13/16
Filed: 1979-07-20
Abstract: An alarm system for detecting unauthorised entry comprises a control circuit and at least one head circuit. The or each head circuit comprises an electro-acoustic transducer 1 whose output triggers a pulse-producing circuit such as a non-retriggerable mono-stable multivibrator 3 when a sound, such as a breaking window, is detected. The control circuit includes a counter 11 which receives output pulses from the pulse-producing circuit and means, such as a timer 12 for resetting the counter 11, for producing an alarm signal when the counter 11 reaches a predetermined count before the expiry of a predetermined period from an initial output pulse of the head circuit or circuits. The system is thus actuated by sounds such as the shattering of glass on the splintering of wood but is substantially insensitive to single sounds such as a bird flying into a window. <IMAGE>
Patent GB-2057780-A (GB)
Title: Strain relief device for terminating a cable
IPC: G02B6/44
Filed: 1979-08-21
Abstract: Where an electrical or fibre optics cable is terminated at a connector or in an equipment unit, it is desirable for there to be a strain relief arrangement to prevent tugs on the cable from damaging the conductors themselves. In the present arrangement this is effected, when the cable has a layer of lengthwise strands 9 between the outer sheath and the conductors, by trapping, the strands between a male 1 and a female 4 member, each of which has a conical surface. By pulling the strands a self-locking of the two members occurs. The cable has been found to withstand greater tensions before breaking in this particular device.   The device could also be used with ropes. <IMAGE>

The force applied by the raised end of a vehicle is supported by ground-engaging wheels (14) of the lifting assembly (4) without significantly affecting the axle loads of the wheels (6) and (8) of the tractor (2). <IMAGE>
Patent GB-2073535-A (GB)
Title: Colour television transcoding matrices
IPC: H04N9/67
Filed: 1980-04-03
Abstract: Transcoding from R, G, B to (R-Y), Y, (B-Y) is achieved (Figure 1) by forming (R-G) and (B-G), multiplying these by 0.299 and 0.114 respectively, adding the resultants together and to G such as to give Y, and subtracting Y from each of R and B. Gain circuitry may be connected to convert the (B-Y) and (R-Y) signals into U and V signals. Transcoding in the converse direction is achieved (Figure 2) by adding (48) (R-Y) and Y to give R, adding (50) (B-Y) and Y to give B, multiplying (52) (R-Y) by a factor 0.299/0.587, multiplying (54) (B-Y) by a factor 0.114/0.587, adding (56) the outputs of the two multipliers and subtracting (58) the resultant from Y so as to give G. In a circuit receiving Y, U and V signals, a gain adjusting circuit is included before the input to each of adders 48, 50, and the multiplication factors of multipliers 52, 54 are correspondingly adjusted. A minimum of multipliers is required in each case, and multiplier errors do not affect grey scale colours. <IMAGE>

Title: Multiple gas turbine speed/temperature response control system
IPC: F02C9/28
Filed: 1982-02-10
Abstract: A closed loop control system is presented which trims fuel flow to the turbine engines of a multi-engine aircraft in response to fan speed and turbine temperature measurements. The closed loop system is activated after the initial climb-out phase of flight. To engage the automatic control system the pilot will first preset a not-to-exceed measured gas temperature for the turbines and secondly, adjust the throttles to bring engine fan speeds within the pull-in range of the synchronizer. This done, the pilot engages the closed loop control system which functions by having fan speed 78 and turbine temperature data 80 signals transmitted to an electronic type master control unit 82. Acting on the incoming signal data, the master control unit pulses power lever actuators 90, 92. There is a power lever actuator serially connected between each throttle lever 86, 88 and the fuel control valve associated therewith. Each power lever actuator is capable of increasing and decreasing the effective preset value of a power lever by an amount just sufficient to maintain speed synchronization and temperature control of the associated engine during the cruise phases of flight. The automatic system has limited authority and the pilot can override at any time by simply moving the throttle levers. <IMAGE>

Title: Method and apparatus for consolidating rock strata
IPC: E21D9/00
Filed: 1982-03-19
Abstract: The rock and coal strata which tend to flake or break out are stuck or nailed to one another in that, simultaneously with the consolidation, anchors or spikes 4 of tubular form are introduced and stuck in the drill hole by means of the consolidating material. The tubular rod consists of material of high strength having an elasticity far above that of steel, and thus is usable especially as anchor in roadways which are heavily stressed at the gallery connection. Possibilities of attachment for high-pressure pumps are produced by suitable ends. A uniform distribution of the consolidating agent in the cavity between rod and drill hole wall is guaranteed by bores formed over the length. A device serving simultaneously as consolidating cartridge, anchor and spike has an interior divided by a partition into two chambers, the chamber walls having apertures closed by the side edges of the partition while the partition carries a mixer head at the upper end and is conducted out of the device at the lower end. <IMAGE>
Patent GB-2102627-A (GB)
Title: Push button switch
Inventor: BECK ROLAND DEAN
IPC: H01H13/702
Filed: 1982-03-23
Abstract: A switch actuating mechanism includes a spring actuating pawl (24) for engaging the teeth (28) of a ratchet wheel (26) mounted rotatably in a casing (11) which also carries a reciprocating spring biased pushrod (14). The spring actuating pawl (24) is mounted on the pushrod (26) and has a stepped portion (36) which effects sequentially driving engagement with individual teeth (28) of the ratchet wheel (26) so that the ratchet wheel (26) is stepped in one direction of rotation upon movement of the pushrod (14) in the forward direction. The spring pawl (24) is deflected downwardly by the ratchet wheel teeth (28) on movement of the pushrod (14) in the reverse direction. The invention reduces required tolerances, push rod operating force and pre-travel requirements, automatically compensates for dimensional variations and substantially eliminates creeping. <IMAGE>
