IPC: H04M15/04
Filed: 1958-05-22
Abstract: 839,939. Automatic exchange systems. SIEMENS & HALSKE A.G. May 22, 1958 [May 22, 1957], No. 16537/58. Class 40 (4). Metering changes are recorded by storing the numbers of subscribers subject to such changes, the storage of said numbers being effected within the minimum period of time which can elapse between successive metering impulses. As described, there is one magnetic recording device for the exchange. When a metering impulse appears at one of the first group selectors, say GW1, a relay Z21 energizes temporarily to energize relay Z3 in the calling subscriber's circuit TS so causing impulses representative of the subscriber's number to be applied over wires T, H, Z, E to the recording device RE. The impulses are coded and the beginning of each code signal is indicated by an impulse on wire A. The individual digits do not need to be in normal order, a signal on lead P restoring the order to normal. The several first group selectors are effective in turn to record metering pulses if they occur.

[Also in Divisions B5 and F1] A rotor blade assembly is formed by interconnecting the root portions of angularly spaced blades by at least one length of fibrous material. The rotor may be a turbine or compressor rotor of a gas turbine engine and is produced by mounting the blades 10 on a jig and rotating the jig so as to wind a large number of turns of the fibres 21 in circumferential recesses 15, 16 in the root portions 12. The fibres 21 may be of carbon or boron and may be passed through an oven (22), Fig. 1 (not shown), and an electrolytic plating bath (23) during the winding operation. In the bath (23) the fibres 21 are coated with a nickel-chromium alloy or with beryllium, cobalt, chromium, nickel, hafnium, niobium, osmium, palladium, platinum, rhenium, rhodium, tantalum or vanadium. Alternatively, the coating may be effected by spraying or vacuum deposition. After winding, the coated fibres are compacted and then bonded in the recesses 15, 16 by placing the jig with its blades 10 in an electrolytic plating bath so as to bond the fibres by the plating material. Alternatively, the bonding may be effected by hot pressing, brazing, or welding using explosion, electron beam, laser or diffusion methods. When this has been done the jig is removed and the blade assembly secured to a disc or drum by bonding or by spacer members secured to the sides of the root portions 12. The coat. ing material of the fibres may alternatively be a synthetic resin material such as an epoxy, polymide, polyquinoxaline or polythiazole resin. In this case, the fibres 21 are bonded in the recesses 15, 16 after winding by injecting further resin material. The blades 10 may be formed of conventional material or of coated fibres the same as the fibres 21.

Title: Improvements in the disposition or lay-out of motor vehicles of the small type
IPC: B60K5/00
Filed: 1942-11-30
Abstract: 562,506. Motor vehicles. AUSTIN MOTOR CO., Ltd., LORD, L. P., and CHARLES, H. N. Nov. 30, 1942, No. 16954. [Classes 79 (ii) and 79 (iii)] In a small motor vehicle the gear-box D, formed separate from the power unit A, is placed at or about the middle of the length of the vehicle approximately under the front seats C and is connected to the power unit by a first propeller shaft F which slopes downwardly from the power unit to the gear-box. The gearbox is connected to the driving axle differential gear E by an upwardly-inclined second propeller shaft G. The floor B can thus be placed at a low level without the use of a shaft tunnel. The lay-shaft of the gear-box may be above or at one side of the main shaft, the gear housing being extended upwardly (as indicated in broken lines) or laterally to accommodate it. The engine shaft is downwardly inclined and makes the same angle with the shaft F as the latter does with the gear-box shaft ; similarly, the angle between the gear-box shaft and the shaft G is the same as that between the latter and the short shaft of'the differential gear. The gear-box shaft, thus runs at uniform velocity although the shafts F and G do not. In a modification, the engine shaft and shaft F are in line and the latter drives the gear-box through a constant-velocity joint. The engine is preferably offset to the near side of the vehicle to allow more space for the control pedals and the driver's feet, and the sloping part b of the floor is extended on the driver's side under the dash to form a pocket H to one side of the engine and thus allow more room for the pedals. The transmission line from the offset engine to the differential gear may be parellel to the centre line of the vehicle or may be inclined thereto. According to the Provisional Specification the gear-box may be either at the engine end or the rear axle end, the shafts F, G being downwardly-inclined towards a point under the front seats where they are supported and connected together by a universal joint.
