Filed: 1932-06-01
Abstract: 393,085. Derailing railway trucks. PALMER, J., The Bungalow, Broom Hill, Heather, Leicestershire. June 1, 1932, No. 15466. [Class 104 (i).] Apparatus for derailing runaway wagons on an incline, comprises a shaft E arranged transversely between the rails and carrying a disc A provided with two projections a, a<1>. A second disc B loosely mounted on the shaft E has a slot b engaged by a pin F on the disc A. The disc B is connected to a slip rail K by linkwork G<1>, G, G<2>. If a wagon is moving at normal speed its axle strikes the projection ? a but does not turn the disc A sufficiently to cause the pin F to actuate the disc B. If the speed is abnormal the disc is turned sufficiently toallow a second axle to engage the projection a<1> and turn the disc A so that the pin F turns the disc B and opens the slip rail. On steep inclines, where the speed of the wagons is high, the second projection a<1> may be omitted. The movement of the slip rail operates electrically a warning bell.

Filed: 1938-05-25
Abstract: 516,223. Hinges. DETROIT HARVESTER CO. May 25, 1938, No. 15653. Convention date, Feb. 11. [Class 65 (ii)] A door hinge comprises an inclined stem portion 19 rotatably mounted in a socket 23 attached to the door post, a crank portion 20 integral with the stem 19 and a connector portion 21 extending from the crank portion and rotatably mounted in a bearing member 26 attached to the door. The stem 19 lies in a plane parallel with the face of the door, the member 20 lies in a plane inclined at an angle thereto, and the member 21 is slightly inclined to the plane containing the axes of the members 19 and 20. The sides of the socket 25 in the bearing member 26 taper towards the lower end of the socket to substantially the circumference of the arm 21 so that the outer end of the arm 21 may have a rocking movement with respect to the door. A washer 28 locates the arm 21 endwise in the bearing 26. On opening the door 10 the arm 20 will rotate about the pivot 19 and the arm 21 will reciprocate in the slot 25 and the angles at which the arms are set with respect to another will allow the door 10 to be swung clear of the body as shown in dotted lines in Fig. 6 and prevent the flange 12 fouling the door post 14. The member 21 is inclined to the plane containing the axes of the members 19 and 20 so that it does not protrude into the trim panel. A modification in which the connector portion is pivoted to the crank portion is shown in Fig. 14. The crank 20a is in the form of a web-shaped member with bearing knuckles 29 supporting a pivot pin to which is attached a sleeve 30 which is in turn connected to door by a screw threaded connector arm 32. The threads cause the arm 32 to move slightly inwards and outwards with respect to the door but also hold in against undesirable axial movement.

Title: Semiconductor device fabrication
IPC: C23C8/00
Filed: 1966-04-07
Abstract: 1,145,488. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 7 April, 1966 [30 April, 1965], No. 15662/66. Heading H1K. An intermediate product from which mutually isolated semi-conductor components can be made consists of a mono-crystalline semiconductor wafer with at least one mesa on one face, and a support body, which is separated from the wafer at least in the region surrounding each mesa by a layer or layers of a material harder than the wafer material. In the preferred embodiment mesas 2 mils high are formed on an N+ silicon wafer by photoresist and etching steps and silicon carbide deposited on the resulting surface from a gaseous mixture of toluene and silicon tetrachloride in the carrier gas hydrogen. Amorphous or monocrystalline silicon of N, P or intrinsic type is then deposited to a depth of 7-8 mils. If desired a layer of molybdenum or tungsten is deposited before the carbide to provide a low resistance current path. In an alternative method silicon dioxide is thermally grown over the prepared surface of the wafer, and the silicon carbide deposited on top of it. A variant of this is to etch the dioxide from the inter-mesa areas and then deposit the carbide on the cleared areas through a silicon mask. In all cases the support body is next lapped down to the silicon carbide around the mesas which acts as a stop preventing the further lapping of the mesas which might otherwise occur in securing a flat surface on a warped body. The lapped surface is covered with oxide masking, which is removed over the centres of the mesas by photo-resist and etching steps. A pit is formed in each mesa by gas etching through the mask and is filled with higher resistivity N-type silicon by epitaxial deposition. Finally the base regions of transistors and resistive tracks and transistor emitter regions are formed in neighbouring mesas by successive masked diffusion processes and the resistors and transistors connected to form a logic circuit by depositing metal over an apertured masking layer and then etching it selectively to form the interconnections. Other hard materials such as alumina and boron may be used instead of silicon carbide.

Title: Improvements in or relating to braking systems for motor vehicles
IPC: B60T13/16
Filed: 1927-06-17
Abstract: 297,339. Lorm³ller, B. June 17, 1927. No Patent granted (Sealing fee not paid). Controlling different functions by same handle or lever.-In a brake for motor vehicles, brake shoes are drawn towards a drum without applying braking pressure by spring pressure normally held off by fluid pressure which is automatically released by means operated by the driver when the vehicle is to be slowed down or stopped, such as the accelerator or clutch pedal, positive braking pressure being applied by an independent brake pedal. The brake shoes 14<b> are adapted to be applied to the brake drum by a lever 12 engaging a collar 13 on the brake rod 14 and a piston 5 operated on by a spring 7, the piston being mantained in the brake release position by liquid circulated by a pump 3 through passages 3, 6. Release of the accelerator pedal 10 opens a valve 2 to release this liquid through another circuit comprising a passage 21. Braking pressure is applied by a pedal 20 adapted to set on the brake rod 14 by means of a housing 15 enclosing rollers 16 which are caused to grip the brake rod, when acted on by inclined internal faces of the housing. In release position, pins 17 engaging fixed abutments 18 maintain the balls in the wider part of a recess containing the rollers against spring pressure. Alternatively, a ratchet wheel may be provided on the rod 14 which co-operates with a pawl on the brake pedal or on an arm thereof. Beside the accelerator pedal may be arranged a foot rest which is movable when the accelerator is pressed until half open position of the accelerator when the foot rest comes against a stop and the accelerator can be further operated by the side of the foot. This makes the control of the accelerator more sensitive. The accelerator pedal controls the throttle through parts 22, 23 and a lever 24.
