Title: Temperature-responsive actuating elements
IPC: G01K5/64
Filed: 1960-10-07
Abstract: 890,064. Thermal switches. MICHEL, J. Oct. 7, 1960, No. 34500/60. Class 38 (5). [Also in Groups XIII and XL (b)] A snap-acting bimetal disc or strip B bears a silver or platinum switch contact C 1  and has two heater resistances printed on a flexible pellicle of phenol-based epoxy resin or cured polyester (or on a pair of such pellicles) stuck to the bimetal. The first heater bends the bimetal to a position near that for snapaction but the bimetal does not snap to the operating position until a current passes through the second heater R 2 . The first heater may be on the same pellicle and side of the bimetal as the second heater R 2  or on a separate pellicle at the other side, Fig. 2b (not shown). The heater R 2  may be in circuit with a photo-electric cell (see Group XL (b)), a thermocouple or a device responding to a chemical factor, for producing a current so that the bimetal snaps to switch on apparatus connected between a holder H and a fixed contact with which the contact C 1  cooperates. The apparatus is switched-off when the current ceases in R 2 . Reference has been directed by the Comptroller to Specification 792,145.

Title: Control unit for vehicle brakes
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/28
Filed: 1964-08-25
Abstract: 1,125,433. Hydraulic brakes. GIRLING Ltd. 22 Nov., 1965 [25 Aug., 1964], No. 34839/64. Heading F2F. In a control unit a braking system of the kind in which an inertia controlled valve 10 is provided between a master cylinder and the slave cylinders of the brakes on one or more pairs of wheels of a vehicle such that braking is continued after closing of the valve at a predetermined rate of deceleration of the vehicle and hydraulic fluid is supplied to the slave cylinders at a rate of pressure variation different from the rate of increase of the master cylinder pressure, the inertia control valve includes a ball 14 adapted to seat against a stationary valve seat 24 provided on a cylindrical member 18 and a differential piston 27 which is movable in one direction when the valve is open and in the opposite direction when the valve is closed such that when braking is continued after the valve is closed, fluid is supplied to the slave cylinders of the brakes at a pressure which increases at a rate less than the increase in the master cylinder pressure. Under normal braking conditions fluid from the master cylinder flows into an aperture 16 in a plug 15 and flows around the outside of the stationary cylindrical member 18 to the slave cylinders of the brakes on the front wheels of the vehicle through outlet connection 26 and through the axial passage 23 in the cylindrical member 18 and the axial passage 38 and radial ports 37 in the differential piston 27 to the slave cylinders of the rear wheel brakes through outlet connection 36. At the same time the fluid pressure acts on the rear end 29 of the differential piston 27 and moves it forwardly against the action of a spring 41. When braking is continued after the rate of deceleration of the vehicle reaches a predetermined value to cause the ball 14 to roll forwardly and engage the seat 24, the slave cylinders of the rear wheel brakes are out off from direct communication with the master cylinder but fluid from the master cylinder flows past the cylindrical member 18 to act on the annular forward face 44 of the larger end 29 of the differential piston 27 and, with the assistance of the spring 41, moves the piston rearwardly to force fluid in a space 45 between the rear end of the piston 27 and the rear end of the recess 22 in the cylindrical member 18 through the axial passage 38 in the piston to the slave cylinders of the rear wheel brakes. The pressure applied to the slave cylinders of the rear wheel brakes is thus increased but owing to the difference in the areas of the ends of the differential piston 33 the rate of increase is less than the rate of increase in the master cylinder.

Filed: 1975-08-22
Abstract: 1464801 Semi-conductor devices SIEMENS AG 22 Aug 1975 [18 Oct 1974] 34867/75 Heading H1K A semi-conductor device is produced by introducing a dopant by ion implantation into a polycrystalline or amorphous layer 6, or a plurality of such layers on the surface of a semi-conductor body 1, and subsequently diffusing the dopant from the layer 6 into the body 1 to form a doped zone. The body 1 may be Si and the dopant As which is implanted into the layer 6 on an oxide layer 3. The layer 6 may be polysilicon which is later etched away partially to leave contact portions for the doped zones in windows in the oxide layer. By this method the maximum of the doping profile remains within the layer 6 even after the diffusion step. There are described transistors having special gain and frequency characteristics, made using this method.

Abstract: 902,182. Steam generators. BABCOCK & WILCOX Ltd. Nov. 12, 1958 [Nov. 12, 1957], No. 35281/57. Class 123 (2). [Also in Groups XXIX and XL (a)] A power plant comprises a gas-cooled nuclear reactor, coolant circulating means for circulating coolant under super-atmospheric pressure through the reactor and through a pressure vessel containing heat exchange means, and regulating means for regulating the coolant temperature at the inlet to the reactor, the regulating means including means within the pressure vessel for by-passing at least part of the heat exchange means and valve means for controlling the flow of coolant through the by-pass. In Fig. 1, the cylindrical pressure vessel 11 contains a casing 21 of square crosssection forming a gas duct and containing eight heat exchange units 23-30. Units 23-26 together with an external steam and water drum 31 form the high pressure boiler, unit 26 being a secondary economizer, units 25 and 24 the vapour generators, and unit 23 the superheater. Similarly, units 27-30 together with an external drum 33 form a low pressure boiler, unit 30 being in two parts, one of which forms the primary economizer for the high pressure boiler and the other of which forms the economizer of the low pressure boiler. A by-pass 52 controlled by a valve 53 is fitted in the segmental spaces between the square casing 21 and the cylindrical pressure vessel 11 and allows some of the gas to by-pass the heat exchange units 29, 30. Coolant from the reactor 2 is fed to the top of the pressure vessel and back from the bottom of the pressure vessel through a compressor 8 to the inlet of the reactor. Compressor 8 is controlled to keep the outlet temperature of the reactor coolant constant and valve 53 is controlled to keep the inlet temperature constant. In another arrangement, Fig. 7, the pressure vessel contains a gas conduit 110 of generally square cross-section to which gas is fed from the reactor (not shown) through conduit 108 and valve 112. The conduit 110 contains three heat exchange units 114, 115, 129 forming the superheater, evaporator and economizer and suitably connected to a boiler drum 144 mounted on top of the pressure vessel. After passing through conduit 110 the gas flows back along the outside of the conduit to the inlet of a centrifugal compressor 104 and then through valve 142 and conduit 143 and back to the reactor. A by-pass 164 controlled by valve 163 allows some of the gas to by-pass all the heat exchange surfaces in the pressure vessel.
