Title: An improved support for glasses and the like for attachment to folding or deck chairs
IPC: A47C7/68
Filed: 1932-10-19
Abstract: 387,975. Table attachments for chairs. WHITE, A. L., 12, Burlington Court, Chiswick, London, EWEN, J. W., 43, Ophir Road, Bournemouth, and RYAN, A. S., 7, The Mount, Forty Lane, Wembley Park, Middlesex. Oct. 19, 1932, No. 29232. [Class 52 (iii).] A tray 6 is removably attached to a pillar 1 mounted on the frame members 11, 14 of a folding chair.

The tray 6 is preferably mounted eccentrically on the pillar 1 and may have a hole 7 leading to a conduit 8, Fig. 1, so that liquid spilled on the tray will drain down the hollow pillar 1. The tray may be held, as by a leather strap, to the back of the chair when folded.
Patent GB-793600-A (GB)
Title: Improvements in or relating to presses
IPC: B30B15/00
Filed: 1956-09-25
Abstract: 793,600. Stamping. SCHULER AKT. GES., L. Sept. 25, 1956 [Oct. 14, 1955], No. 29313/56. Class 83 (4) A press with multi-point drive of the sheet-metal holder and/or ram and having a device for the adjustment of the spindles which transmit power to the drive points and also a common drive of the adjusting members is characterized in that independently-operable clutch couplings are inserted in the drive-shafts of the adjusting members and the angle through which the two clutch halves of these couplings can be turned relatively to one another is limited by a driving arrangement bridging the coupling. In a deep-drawing press the sheetmetal holder 1 is driven by connecting rods 2 linked to spindles 3 fixed by spindle nuts 4 in the holder at its four corners. The drive of the spindle nuts 4 for adjusting the holder is effected by a motor 5 through bevel gearing to a gear-wheel 12 on a shaft 13 and through a clawclutch to the spindle nuts. A spring-loaded coupling sleeve 14, slidable on the shaft 13, has claws 16 which engage corresponding claws on the clutch half 15 rigidly connected to a bevel wheel 17 meshing with a toothed rim on the spindle nut. The clutch is operated by a hand lever 20 on a shaft 19. When adjusting the holder, to prevent it canting beyond an admissible extent, the sleeve 14 is provided with a driver 26 and the clutch half 15 with a stop 27 which overlaps the sleeve. Thus with the coupling disengaged, the driver 26 after one revolution, carries the clutch half 15 with it to drive the spindle nut. The rotation of each clutch half 15 is transmitted by chain and sprocket wheels and gearing to an indicator 38 on a shaft 37. Rotatably mounted on the shaft 37 is a graduated disc 39 which is driven from the shaft 13. With the couplings closed the indicators and discs associated with each drive point rotate together at the same speed but if a coupling is opened its indicator will remain stationary thus the relative rotation between the indicators and the discs is a measure of the degree of cant of the holder. In a modification an intermediate ring 52 having a stop 54 for engaging the driver 26 is rotatably mounted on the clutch half 15<SP>1</SP>. Opposite the stop 54 on the ring 52 is a driver 55 for engagement with a stop 56 on the clutch half 15<SP>1</SP>. Interposition of the ring 52 makes it possible for the clutch half 15<SP>1</SP> to be driven only when the sleeve 14 has rotated more than 360 degrees. Alternatively, the clutch half 151 may have an extension overlapping the sleeve 14, the inside wall of the extension having a stop for engaging the driver 26. In another embodiment electrical contacts are disposed on the clutch halves for stopping the motor 5 or for closing an electromagnet when the maximum permissible cant is reached.

Abstract: 1501110 Adjusting vehicle suspension height MOULTON DEVELOPMENTS Ltd 23 June 1975 [2 July 1974] 29315/74 Heading B7D A rear suspension comprises hydraulic displacer units 10, 11 of the varying rate type associated individually with the suspensions of respective rear wheels, a pipe 50 providing communication between the displacer units, a branch 52 extending from the pipe 50 to a reservoir 51, a solenoid valve 53 operable to allow flow through the branch 52, and a pump operable to pump fluid from the reservoir 51 into the pipe 50. Each displacer unit 10, 11 communicates through a damping valve 20 with a gas spring 18, 19 and acts through a strut 12 on a transverse, trailing or semi-trailing suspension arm 14 carrying a wheel hub 16. A torsion bar 70 which is connected between the arms 14 and may serve as an anti-roll bar has fixed to its central region a fork 78 for actuating time-delayed switch mechanism 103. The fork 78 co-operates with a spring leaf 75 which is connected to a rotary damper 76 and is arranged, in dependence on the direction of rotation of the torsion bar, to close one of micro-switches 71, 72 which energize a winding 54 for opening the valve 53 or a relay 73 for operating a motor 57 which drives the pump 56. A non-return valve 55a is arranged on the output side of the pump 56, and a switch 74 operated in conjunction with the ignition switch of the vehicle prevents operation of the pump unless the ignition is switched on. Roll damping may be obtained by suitable sizing of the pipe 50 or by providing a constriction in the pipe.

Title: Improvements in the steering mechanism of tanks and like vehicles
IPC: B62D11/08
Filed: 1937-10-27
Abstract: 498,764. Steering vehicles by controlling driving gear. AUSTIN, B. A. Oct. 27, 1937, No. 29324. [Class 79 (ii)] In endless-track vehicles provided with a steering clutch and brake a or b for each track, a free-wheel device c is arranged between the driving and driven members a<2>, a<1> or b<2>, b<1> of uach clutch in such a way that it prevents the driven member from over-running the driving member when the clutch is disengaged but allows the driven member to be slowed down by the brake on full movement of the steering lever. This arrangement prevents what is known as " reverse steering," which is liable to occur when the vehicle is going downhill or is slowing down and the engine is therefore acting as a brake, with the result that if the steering lever is moved to disengage one clutch the corresponding track, being freed from the braking-effect of the engine, accelerates instead of slowing down and the vehicle steens in the opposite direction to that intended. Means are provided for rendering the free-wheel clutches c inoperative during reverse muvement. Such means may be automatically brought into action by the reverse rotation of the mechanism, but in the construction shown the gear lever d is connected by linkage and shafting 1, m, i, g to plungers e for locking the clutches c when the lever is put in the reverse position.

Filed: 1920-10-18
Abstract: 174,412. Hargreaves, P., and Johnson, J. E. Oct. 18, 1920. Condenser systems.-In a condenser system in which a main condenser A is exhausted by a steam-jet air-pump comprising two jets b, b<1> in series separated by a water-jet condenser B in which condensate from the main condenser A is used as cooling medium, the effluent from the condenser B passes through a U-tube 1 and thence either by a pipe 2 into the condenser A or by a pipe 3 into a tank 4 at the base of the condenser. The tank 4 is divided by a weir, which may be adjustable, into a retaining-compartment 6, Fig. 2, and a discharge compartment 7. The compartment 6 contains a float which closes a valve 15 on the outlet of the pipe 3 when the level falls, due to the engine being on light load and the supply of condensate small. The effluent from the condenser B then passes through pipe 2 and is cooled before being mixed with the condensate in the tank 4. In an alternative arrangement, the steam-supply to the first jet b is controlled by the float so as to be reduced when the float falls.
