Title: Safety devices for internal combustion engines
IPC: F02B3/06
Filed: 1972-07-28
Abstract: 1352093 Internal-combustion engine stop gear MOTOREN-UND TURBININ-UNIONFRIEDRICHSHAFEN GmbH 28 July 1972 [31 July 1971] 35451/72 Heading F1K A liquid cooled internal-combustion engine has a safety device connected to detect both the pressure of the coolant and the pressure of the lubricating oil of the engine, the safety device being arranged to interrupt the fuel supply to the engine if the instantaneous lubricating oil pressure falls below a predetermined minimum value corresponding to the instantaneous value of the coolant pressure. The lubricating oil pressure acts through a pipeline 27 in the chamber 20 and the cooling water pressure acts through a pipeline 29 in a chamber 30. If the cooling water pressure predominates the pistons 12, 13 are moved to the right. The pressurized  lubricating oil in the pipe 28 can then enter the chamber 31. The spring 18 then pushes the piston 13 to the right and shuts the line 27. The governor 24 can then no longer function and the engine stops for lack of fuel.

Title: Improvements in or relating to semiconductor devices
Inventor: SETCHFIELD JOHN BERNARD
IPC: H01L23/482
Filed: 1964-09-02
Abstract: 1,046,187. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Aug. 6, 1965 [Sept. 2, 1964], No. 35926/64. Heading H1K. A method of manufacturing a semi-conductor junction device, such as a tunnel diode, includes the steps of providing a layer of semi-conductor material of one conductivity type on part of a face of an effectively insulating base, providing an electrically conducting layer on another part of the face spaced from the semi-conductor layer, placing a pellet of impurity material of opposite conductivity type in the space with the pellet in contact with both layers, and heating so that the impurity material is alloyed with the semiconductor layer, to form a junction therein, and also with the conducting layer, to form an ohmic connection therewith. A base 1 of semiinsulating gallium arsenide has a layer 2 of P+ germanium epitaxially deposited on one face. Part of the layer is then removed and gold layers 3a, 3b are evaporated over the stepped surface except over areas 4, 5 and 6. The gold layers are then alloyed in and built up by electroplating, and a tin-arsenic sphere 7 is placed in the gap 4 between the gold layer 3a and the semi-conductor layer 2 so as to contact both layers. Heating in a non-oxidizing atmosphere results in the formation of a tunnel junction, and the step 5 is then electrolytically etched to form a narrow neck 8 (Fig. 5, not shown) equivalent to the upstanding neck in conventional tunnel diodes. In a modification (Figs. 10-13, not shown) the layer 2 is removed until only a transverse ridge 17 remains. The base 1 may alternatively consist of a single crystal sapphire, and the semi-conductor material may be gallium antimonide. Forms of diode suitable for direct connection to a coaxial line or strip line are also described.

In process (a) inert organic solvents and catalysts such as tin tetrachloride, organic compounds of tin and dibutylzinc may be used. Either the cis- or the trans-form of the cyclobutanediol or mixtures of the two may be used. In process (b) the acid binding agent may be excess amine or an aqueous solution of an alkali metal hydroxide or carbonate.  If an aqueous acid-binding agent is used an inert, water-immiscible, organic solvent may be added to give an interfacial reaction system. The products are useful as fibres and films, moulding and coating compositions, interlayers in safety glass and in the production of foams when the bulk polymer may be blown with carbon dioxide.

Abstract: 1304907 Electro-erosion ATELIERS DES CHARMILLES SA 27 July 1970 [7 Aug 1969] 36279/70 Heading B3V [Also in Division F1] In an electro-erosion machine wherein the electrode E is moved relative to the workpiece P by a piston and cylinder unit 3, 6, the piston rod 2 of the unit is clamped by a surrounding clamp, A, B, constricted radially by a spring force, when the pressure of the fluid fed to the cylinder 6 falls below a predetermined value. The rod 2 is rotatable by a motor M 2  mounted in an arm 29 slidable on a column 30, the cylinder 6 being sealed by bearings 34, 35. The clamping device A, Fig. 2, for preventing linear movement of the rod 2 is mounted on the bearing 34 and comprises an elastic ring 7 clamped to the rod 2 by spring clasps 17. When fluid under pressure is fed from a reservoir 22 to the cylinder 6 so as to control the spacing between electrode E and workpiece P, fluid is also fed via a valve 21 through a conduit 15 and the ring 7 so as to unclamp the ring 7 from the rod 2. Rotary movement of the rod 2 is prevented by a similar ring 7 of a clamping device B which is connected to the slidable arm 29. The ring 7 is fixed to a gear wheel (26), Fig. 3 (not shown), which co-operates with a worm (27) turnable by a handle 63 to allow angular adjustment of the electrode E. In another embodiment a wedge shaped portion (43) (Fig. 4, not shown) of a clamp (42) is pressed into engagement with the rod 2 by a spring (45). When the machine is operative the clamp (42) is disengaged from the rod 2 by fluid under pressure entering a chamber (40). In a similar embodiment (Fig. 5, not shown) the clamp (52) is disengaged from the rod 2 by fluid pressure acting on an annular sealing diaphagm (58).
