Patent GB-2076062-A (GB)
Title: Turbine power plant
IPC: F01K23/06
Filed: 1981-05-15
Abstract: In the plant the exhaust air from a power turbine 2 supplies a fluidised bed combustor 1 and a waste heat boiler 7 in parallel. The proportion of exhaust air supplied to the fluidised bed combustor is controlled by means of a valve B in the primary airflow path of the combustor. The throughput of the power turbine can therefore exceed the primary air throughput of the combustor allowing an extended reduction of power whilst maintaining the temperature of the bed within its operational range. The input air of the power turbine 2 is heated by being passed through a secondary air flow path 17 of the combustor, the path 17 being isolated from, but in thermal contact with, the combustor bed. The waste heat boiler 7 drives a steam turbine 8 coupled by differential gearing to the power turbine 2 to produce a common output drive. <IMAGE>

The undergarment is premoistened and the wrapped cast preforms are moistened in order to activate the prepolymer composition. The cast is then allowed to cure to a rigid foam material.
Patent GB-2084917-A (GB)
Title: Improvements in or relating to percussive tools
IPC: B25D17/06
Filed: 1981-10-07
Abstract: A percussive tool such as an electric or pneumatic hammer including a reciprocating striker 10 striking an anvil 13 which is slidably mounted in a cylinder and which in turn strikes an implement, incorporates a device for preventing rebound of the anvil towards the striker when the implement is moved away from the workpiece allowing the anvil to move forward beyond its normal operating range of movement. The device comprises a venting valve formed jointly by a land 28 on a reduced-diameter portion 21 of the anvil and an annular constriction 29 in the bore in which portion 21 reciprocates. The venting valve operates to vent the cylinder space 30 at the rearward side of the anvil in its most forward and rearward positions only. Thus, rebounding of the anvil from its idle, i.e. most forward, position seals the cylinder space 30 and causes the pressure therein to rise and resist further rearward movement of the anvil. <IMAGE>

Title: Flame Detector
IPC: G01J1/58
Filed: 1981-11-26
Abstract: A detector head 1 is equipped with an ultraviolet filter 3 and a wavelength converter 4 which at about 250 nm converts ultraviolet radiation into longer wave radiation above 600 nm. this longer wave radiation is transmitted via a radiation conductor (optical fiber) 6 to a radiation receiver 8 arranged remote from the detector head. This arrangement enables a selective detection of both liquid fuel flames and gas flames. The detection is not influenced in its functional reliability by background temperature radiation and not influenced by the action of heat. Examples of short afterglow phosphors for use in the wavelength converter are given, e.g. Mn-doped silicates, MgO activated with Mn<4+> and containing As2O5, TiO4 or GeO2 or a further additive of MgF2 or Al2O3 activated with Cr2O3, or of the type containing 3Cd3(PO4)2.CdCl2-0.05 Mn<2+> as the active substance. <IMAGE>

Patent GB-2127890-A (GB)
Title: Fastening device
Inventor: ROBINSON ERIC OVINGTON
IPC: E05C1/04
Filed: 1982-09-30
Abstract: A fastening device comprises a bolt 20 slidable with clearance 22 in housing 12 for co-operation with a keeper 38.

Title: Apparatus for filling and compacting material in bags
Inventor: GAUKLER FRITZ
IPC: B65B61/24
Filed: 1982-11-09
Abstract: A bag filling and compacting apparatus has a conveying device (11) cyclically conveying the bags (b). So that bags of flexible soft packaging material receive a shape with uniform walls during compacting of the filling material settling therein, the conveying device has flight walls and base plates (23) which enclose the bags during the filling and compacting of the filling material fully flat up to the upper edge of the bag. The base plates can be raised and lowered and can be brought into operative association with a vibrating device. The flights travel between lateral guide walls (40,41) which are cyclically movable towards and away from each other during the conveying run to give a package of uniform shape. <IMAGE>

Title: Rail vehicle brake
Inventor: HOLLAND JAMES EDWARD
IPC: B61H15/00
Filed: 1983-02-02
Abstract: The brake has brake blocks 8, 10 pivotably mounted on pivotably mounted hangers 20, 22 and applied against rail wheel 2 in response to operation of a piston and cylinder unit 44. Housings 50, 52, to which the hangers 20, 22 are pivotally connected, are interconnected by pull rods 54, 56 each having threaded parts 58 and 60 of opposite hand threadably engaging housings 50 and 52. At one end of the pull rods slack adjuster 68 can rotate pinions 66, 64, (62) rotating the pull rods, when travel of the blocks and/or hangers between brake released and brake effort exerting conditions becomes excessive. As shown, excessive stroke of the piston 47 in unit 44 is detected, a conduit 55 is opened and a fluid pressure signal is applied to slack adjuster 68. In response the slack adjuster rotates the pull rods through a pre-determined angle when the brake is released. This rotation moves the housings 50, 52 closer together simultaneously. Pinions (62) 64 may move axially or remain in same axial position; in either case, casing 70 moves with housing 50. In Figure 3, the casing 70 and housing 50 are separate so that casing 70 remains stationary. <IMAGE>
