Abstract: 1,134,883. Dry shavers. GILLETTE CO. 24 Nov., 1965 [24 Nov., 1964], No. 49996/65. Heading B4B. [Also in Division C7] A shearing foil for a dry shaver comprises a perforated base sheet 3<SP>1</SP> electrolytically coated with harder material 4<SP>1</SP> which provides sharp cutting edges 5<SP>1</SP> but leaves uncoated that side of the base sheet which will face a blade of the shaver. Fig. 1 (not shown) illustrates making a foil base sheet (3) by electrolytically depositing resilient material, e.g. Ni, on to a metal die (1) having an insulating layer (2) with a configuration corresponding with that of the holes to be produced in the foil. A layer of harder material (4), e.g. of Cr, Rh or hard Ni, is electrolytically deposited on the base sheet (3) while still on the die. Prior to this deposition of harder material, portions of the base sheet may be masked with varnish. The base sheet (3) and harder material (4) may both be electrolytically deposited from a bath of the same composition but using different current densities. During use the shaver cutter causes the foil to wear, the less hard material wearing more than the harder material as illustrated in Fig. 3 (not shown).

Abstract: 1,090,457. Semi-conductor devices. TELEFUNKEN PATENTVER WERTUNGS G.m.b.H. Dec. 11, 1964 [Jan. 8, 1964]. No. 50513/64. Heading H1K. In a semi-conductor device, such as a transistor or solid-circuit, conducting strips for making electrical contact to the device are arranged at least partially one above the other and separated from one another by insulating layers. Each of the three specific embodiments is a planar transistor. The transistor of Fig. 1 (not shown) is designed for use in grounded base connection. The surface of the transistor is coated with an insulating layer (2) except in the region of the base and emitter contacts (3, 4). An insulating patch (5) is deposited and a conducting strip (6) deposited over this and the base connection. A further insulating patch (8) is deposited and then a conducting strip (9) making contact with the emitter contact. The base strip is made larger than the emitter strip so that it may act as a capacitative shield to isolate the emitter strip and collector region. If a similar transistor were designed to operate in grounded emitter configuration the positions and shapes of the base and emitter strips would be interchanged. In the embodiment of Fig. 2 (not shown), the base strip (7) again acts as a capacitative shield between emitter and collector but also has a separate area, over a further patch of insulation (6), to which the base lead- (8) is attached. In the transistor shown in Fig. 3 an insulating patch 5 is provided on to which is deposited a conductive layer 12. The base and emitter strips 6, 9 are deposited sideby-side on an insulating patch 8 deposited over part of the conductive layer 12. A lead 13 is connected to the conductive layer which may be thus connected to any desired potential source. Here, both emitter and base connections are shielded from the collector region. The conducting strips are stated to be vapour deposited and it is stated that the insulating patches may be provided by vapour deposition of SiO or SiO 2 , or by thermal decomposition of silicon tetraethyl ester. Reference has been directed by the Comptroller to Specification 1,011,501.

The cartridge (23) is fired electrically by the closing of a switch (36, Fig. 3, not shown), a plurality (e.g. four) of which are arranged in parallel, each held open by the weight of a plumb weight (5) which when it reaches the ground allows the switch to close. The circuit also includes an arming device comprising a switch (37) closed during the descent by a wind vane (41) prevented from rotating until deployment of the parachute by a pin (39) attached to a static line (40). The piston (13) is fixed until the cartridge is fired by a shear pin (42), and is held at the end of its stroke by a locking device (31).

Title: Improvements in hydraulic damping devices
IPC: F16F9/512
Filed: 1965-12-10
Abstract: 1,124,357. Hydraulic damping devices. SCHWEIZERISCHE WAGONS - UND AUFZUGEFABRIK A.G. 10 Dec., 1965 [16 Dec., 1964], No. 52474/65. Heading F2S. In an hydraulic damping device, e.g. for an automatic door closing device, the liquid flow through a piston 13 from one variable volume chamber 11 or 12 in a cylinder 10 to the other variable volume chamber 12 or 11 is controlled by a spring-loaded bobbin-shaped valve 23 which has end flanges 20, 22 which slidably engage the walls of a cavity 15 in a central body portion 13a in the piston 13, the flange 22 controlling the flow of liquid through radial passages 18 in the piston body portion 13a, and by a metering needle 26 which is fixed to the base of the cylinder 10 and co-operates with a central opening 21 in the flange 20 of the valve 23. As a piston-rod 14 moves out of the cylinder 10 against the action, e.g. of a door closing- spring, not shown, liquid flows from the upper chamber 11 to the lower chamber 12 through a set of radial passages 17 in the upper end of the piston 13, the metered opening 21 and into the hollow interior of the valve 23 from which it escapes through radial passages 24 in the valve 23 and through the radial passages 18 which are fully open, the valve 23 being urged downward to abut a bottom plate 16 of the valve 23 by the combined force of a loading spring 25 and the pressure differential developed across the opening 21. In this manner little resistance is offered by the damping device to an opening movement of the door. On a closing movement of the door, liquid flows in the reverse direction, the flow of liquid through the opening 21 becoming progressively smaller and the passages 18 being closed by the valve flange 22 by an amount corresponding to the degree of superiority of the lifting force, due to pressure differential across the opening 21, over the downward force of the spring 25, the lifting force being a function of the velocity of the piston 13. The piston 13 also carries a safety valve 28. The flange 22 may be located on the other side of the flange 20. A non-apertured flange 22 may be employed, in which case a tubular member, having an inner surface whose cross-section varies axially, is interposed between a smaller diameter-flange 20 and the wall of the cavity 15. The metering needle 26, which modifies the point of equilibrium between the force by the liquid on the flange 20 and opposing force of the spring 25, is replaced by one of constant diameter when a non-linear characteristic spring 25 is employed to modify the equilibrium point. In a modification, Fig. 3 (not shown), the chambers (11, 12) communicate through an external duct (18), a valve (22) in which is regulated according to the hydraulic lifting force on a disc (20), which works in a cavity (15), and the opposing force of a spring (25), a metering pin (26) which is associated with an opening (21) in the disc (20) being carried by the piston-rod (14) of the piston (13) which works in a cylinder (10) and which is fitted with a safety valve.
