Title: A motor vehicle self-levelling suspension
IPC: B60G17/04
Filed: 1964-03-13
Abstract: 1,015,250. Vehicle suspension. ROMEO S.p.A., ALFA. March 13, 1964 [March 14, 1963], No. 10860/64. Heading B7D. A motor vehicle self-levelling suspension comprises an hydraulic piston and cylinder 29, 28 interposed between the vehicle axle 23 and the body 25 and connected in parallel with a hydropneumatic suspension device 26 and with a supply of fluid pressure from a volumetric pump 6 with the interpositioning of a control device. The control device comprises a valve spool 1 connected at 2 to the vehicle axle and slidable in a valve body 3 connected, with the aid of resilient members 4, to the body 25. The valve spool has annular " valleys." 7 and 20 bounded by lands and the body member 3 has ports 8 and 9, a connection 5 to the fluid supply and return passages 21, 18 to the fluid reservoir 19. The ports 8 and 9 connect with spaces 10, 11 of a cylinder on either side of a piston 12, the piston being centred by springs 13 and 14. The suspension members 28, 29 and 26 are connected by a fluid line 17 with the cylinder through a non-return valve 16 closed by a spring 22. In a medial position, and for small movements of the axle 3 relatively to the body, fluid from the supply line 5 passes through the ports 8, 9 and passages 21 and 18 back to the reservoir 19 and the suspension members are isolated by the valve 16. If the axle moves downwardly relatively to the vehicle, the port 8 is opened to reservoir and fluid pressure enters the space 11 with consequent upward movement of the piston 12 and opening of the valve 16 by means of a stud 15 attached to the piston, whereby fluid from the suspension is exhausted to reservoir. If the axle moves upwardly relatively to the vehicle, the port 9 is opened to exhaust and pressure fluid flows through the port 9. At the extremity of movement of the piston 12, pressure build-up in the space 10 opens the valve 16 and pressure fluid flows to the suspension device.

Title: Improvements in signal transmission over submarine cables or the like
IPC: H04B3/20
Filed: 1930-04-09
Abstract: 352,098. Two-way terminal equipment. STANDARD TELEPHONES & CABLES, Ltd. and GROVE, S. H., Columbia House, Aldwych, London. April 9, 1930, No. 11307. [Class 40 (iv).] In a submarine cable system the terminal relays are controlled by energy transmitted by radio. The system illustrated has a normal speech bias from E-W and when speech passes in this direction the relay S3 is operated to short the transmitter T1. When speech originates at W it passes through amplifier A1 and delay network D whilst detector amplifier DA2 operates S1 to change over the outgoing leads and controls the sending of a signal current via radio transmitter RT to the receiver RR. This radio signal, travelling faster than the cable signals, operates S2 before the speech currents arrive, connecting the cable to receiver R2 via amplifier A4. The switching at intermediate repeater stations may be similarly operated.

Abstract: 456,409. Feeding webs. JAGENBERGWERKE AKT.-GES., 107, Himmelgeisterstrasse, Dusseldorf, Germany. April 23, 1936, No. 11598. Convention date, April 23, 1935. [Class 100 (i)] In web-rewinding apparatus of the kind in which the roll R is supported on two driven carrier-cylinders I, II, a web-advancing roller V or equivalent device is arranged to co-operate with the cylinder I between the slitters 4, 5 and the winding-up point adjacent to the cylinder II so as to keep the web under tension during the slitting operation and decrease the tension at the winding-up point. The roller V is pressed by springs or weights towards the cylinder I and preferably has a rubber covering. It may be replaced by endless bands. In order to regulate the web tension adjacent to the winding-up point, the drives of the roller V and cylinder I are adjustable. Preferably, the members V, I are driven at a slightly greater speed than the cylinder II so as to decrease the web tension adjacent to the cylinder II, but they may be driven at a slower speed so as to obtain a tighter winding. In order to maintain the pressure between the cylinders I, II and the roll R at a constant value as the roll increases in size, the roll spindle 9 is supported by hooks 13 on chains 12 passing over drums 20, the shaft 21 of which carries cams 22 over which pass chains 23 having counterweights 24 attached thereto. By means of handles 16 operating eccentrics in the shackles 18 connecting the chains 12 to the hooks 13, the effective support. ing force at each end of the web roll can be varied. The web may pass over the face of a suction-nozzle acting as a braking-device, prior to reaching the slitters, so that braking of the supply roll 1 is unnecessary.
