Title: Pressure clamp for mounting semiconductor packages
Inventor: BENNETT ROGER FILLMORE CALMEAD
IPC: H01L23/40
Filed: 1982-12-09
Abstract: A semiconductor capsule clamp comprises a generally bowed spring 1 and a spring loading member 6. A capsule (not shown) is positioned under a centre section of the spring against, for example, a heat sink (not shown) and as the loading member 6 is bolted down onto the heat sink it abuts the ends of the spring 1 thereby exerting a compression on the capsule through cantilever action. An indicator wire element 34 is included in the assembly. In the unstressed condition this element is located loosely in the assembly adjacent to the spring but has a part 35 which is arranged to be trapped when a pre-arranged loading is applied to the spring. A correct loading may therefore be sensed by testing the indicator wire element for looseness. <IMAGE>

Patent GB-2119048-A (GB)
Title: Anchor bolt
Inventor: MCINTYRE DOUGLAS OWEN
IPC: F16B13/04
Filed: 1983-03-01
Abstract: An anchor bolt comprised of an anchor rod (1) which has a screw-threaded portion at one end and a head (2) at the other, which enables the bolt to be torqued-up in use, and an abutment (5) between the head (2) and the screw-threaded end portion. An expansion body (3) is threadedly received on the screw-threaded portion, and a first sleeve member (7) expansible by the expansion body arranged on the rod (1) between the abument (5) and the expansion body (3). A second sleeve member (10, 12) is arranged on the rod (1) between the rod head (2) and the abutment (5), together with a spacer element (8, 11, 13, 14, 19) over which the second sleeve member (10, 12, 15) can slide as the expansion body (3) is drawn axially of the rod (1), to expand the expansible sleeve member (7), when the anchor bolt is being set in a receiving socket (R). The arrangement is such that the bolt can be fully set in the receiving socket (R), with an object to be clamped (S) thereby pulled hard against the receiving surface (M) before, or just as, the second sleeve member (10, 12) is in contact both with the rod head (2) and the abutment (5), so avoiding uselessly loading the second sleeve member (10, 12) in an effort to fully clamp the object (S) in place. At the same time the spacer element (8, 11, 13, 14, 19) occupies or substantially occupies the space between the second sleeve member (10, 12) and the rod (2) thus maximising antivibration efficiency.
Patent GB-2119882-A (GB)
Title: Vehicle anti-lock braking control
Inventor: BREARLEY MALCOLM
IPC: B60T8/1763
Filed: 1983-04-19
Abstract: A vehicle anti-lock brake control system includes wheel speed sensors (S1 to S4) which input speed signals to a microprocessor (11) via an interface circuit (10). The microprocessor is programmed to calculate the deceleration of each wheel, compare this with a threshold and output a signal to a brake release device (A,B,C) for as long as the deceleration exceeds the threshold. The threshold level is calculated by the microprocessor as a function of the time elapsed since the threshold deceleration is exceeded. Initially the threshold is relatively low, but rises with time elapsed. After a predetermined time interval the threshold falls to a new relatively low level which depends on the slip of the wheel. If the slip of the wheel remains higher than a set level following re-application of the brake, a low "fast re-trigger" threshold level is established so as to release the brakes again rapidly if excessive deceleration is again detected or expected acceleration levels are not attained. <IMAGE>

Title: Optical fibre cable preparation tool
Inventor: NICHOLLS WESLEY DURHAM
IPC: G02B6/245
Filed: 1983-06-28
Abstract: A positioning barrel C rotatably supports a cutter A which, when the whole tool is passed onto a fibre optic cable for preparation purposes, is closed onto the protective cable sheath when an adjusting screw E is rotated. The screw E is rotated until resistance is felt, the cutter is then rotated by a key D causing the sheath to be cut evenly, the screw is retightened followed by further rotation of the cutter. Tightening of the screw and rotation of the cutter is continued until the sheath is almost fully parted which coincides with the cutter being in the fully closed position. The parted and unwanted section of the sheath may then be eased away from the cable assembly and withdrawn by careful manipulation of the whole tool. <IMAGE>

Patent GB-2162836-A (GB)
Title: Optical fibre grating structures
Inventor: BYRON KEVIN CHRISTOPHER
IPC: G02B6/34
Filed: 1984-08-14
Abstract: A grating structure is produced in a short length of optical fibre consisting of porous glass impregnated with photosensitive material, by transmitting a laser beam in a standing wave in a Fabry-Perot resonator comprised by the short length of fibre. The laser beam serves to cause a periodic variation in refractive index of the optical fibre by photodissociation of the photosensitive material, which variation can be made permanent by a heat "fixing" process. The grating spacing can be increased or decreased following fixing, by pulling the fibre to a smaller diameter, or heating the fibre to reduce its porosity, respectively. The grating spacing can thus be matched to a required operating wavelength.
