Multi-way valves controlling the fluid supply and exhaust to and from hydraulic or pneumatic devices for regulating the raising and lowering of a motor vehicle seat consists of an actuating lever 17 with a T-shaped handle 21 universally mounted in a rubber bush 15. The lever 17 engages a forked member 22 pivoted on valve 9 which member coacts with pins 26, 27 to operate the valve, whereby pipe 27<SP>1</SP> is either connected to a supply pipe 26<SP>1</SP> or an exhaust pipe 27<SP>11</SP>. A member 28 also on the lever 17 has forked projections 29, 30 guiding pins 31, 32 carried by members 33, 34 on pivots 42, 43 on two further valves 7, 8, the members 33, 34 co-operating with pins 38, 39 and 40, 41 respectively. The pins 12, 13 are guided by slots 12, 13 in the casing. A spacing sleeve is mounted on the stem 17 between bush 15 and member 28. The seat height is adjusted by lifting or depressing the handle 21 along arrow 24 to actuate valves 7, 8. Rotation of the handle operates the valves 7, 8 in opposite senses so that seat is e.g. raised at the front and lowered at the rear. Each valve may be separately actuated by vertical movement of one end of the handle 21 so tilting the lever 17. Horizontal motion of the handle 21 operates valve 9 to cause forward or rearward movement of the seat. Composite movement of the handle effects a combined operation of the valves. Provision may also be made for the handle to move axially in the bush to actuate a further valve controlling movement of the back of a seat.

Abstract: 495,953. Bed-settees. DUCROT, A. May 17, 1938, No. 14742. Convention date, May 28, 1937. Addition to 489,527. [Class 52 (ii)] In a bed-settee of the type described in the parent Specification the use of a fixed frame is avoided by supplementary legs pivoted to that portion of the frame which is rigidly connected to the seat. The legs 22 are pivoted at 24 to the portion C1 of the bed frame and support it in the bed position ; they are also connected by links 25 to the median section of the frame C2, the pivot points being so chosen that the legs remain approximately vertical and continue to support the rear of the settee during the first part of its folding movement. When completely folded, the rear of the settee is supported by the castors 12 of legs 11 rigid with the section C1, and the front is supported by the panel d, the legs 14 having folded up. On either side of the settee a vertical panel 26 secured to the median part of the frame C2 is provided to conceal the mechanism ; when the settee is extended the panel is lifted with the bed as shown. In a modification the fixed legs 11 are no longer used and the legs 22 are connected to the part C2 by a lever which is itself connected by a link to the leg 14. As a result the leg 22 supports the bed in the extended and folded positions and the leg 14 is compelled to assume an upright position when the bed is opened.

Filed: 1973-03-28
Abstract: 1453059 Passive restraint system for vehicle passengers LUCAS ELECTRICAL Ltd 21 Feb 1974 [28 March 1973] 14793/73 Heading B7B  A padded restraint arm 11 can be held in its inoperative position by a permanent magnet 24 chosen effect is neutralized by a coil 23 when the vehicle's ignition circuit is completed so that the arm can turn about its pivot 12 to its operative position under the influence of a spring (not shown). The arm 11 is coupled by a telescopic link 13 to an inertia ratchet mechanism (not shown) which locks the arm when the vehicle deceleration exceeds a predetermined rate. The arm 11 carries a member 18 of magnetic material on which the magnet 24 acts through a core 22 and a U-shaped member 19. After energization of the coil 23, the arm swings away, and after it has moved far enough for the member 18 to be clear of the influence of the magnet, the link 13 pivots an arm 28 to open contacts 27 and de-energize the coil 23, thus avoiding further dissipation of power. If the restraint arm 11 is moved back to its inoperative position while the ignition switch is closed, the contacts 27 will themselves close to energize the coil and prevent retention of the restraint arm 11 in its inoperative position.

Abstract: 791,766. Sheet-delivery apparatus. POWERS-SAMAS ACCOUNTING MACHINES, Ltd. May 16, 1956 [May 25, 1955], No. 15143/55. Class 100(1) [Also in Group XIX] In apparatus for delivering record cards in a statistical or other machine, a card which is being moved leading edge first and face uppermost, can be reversed so that it is moved opposite edge first and reverse side uppermost. Normally, the cards C pass between feed rollers 1, 2 and 3, 4, and are guided by elements 6 into a receiver 7, face uppermost and leading edge 16 first (Fig. 5). On the receipt of a signal a deflector plate 8 is pivoted downwardly to the position shown in full lines, Fig. 4, and the leading edge of a card is deflected upwardy between feed rollers 18, 20 which feed the card on to a fixed plate between a roller 23 and a spaced drop roller 24. When the roller 24 is actuated by a cam and lever means to approach the feed roller 23, the card is fed downwardly between feed rollers 18, 34, over a guide element 36, and into the receiver 7; thus this card is delivered opposite edge 17 first and reverse side uppermost. Since all the cards C are cut away at one corner, the corner 37 of the reversed card will protrude beyond the stacked cut-away edges 38, Fig. 5, of the other cards, and is readily seen. The deflector plate 8 could be operated by a Bowden cable means; but as described, it is operated by a solenoid which is de-energized when the circuit is broken as the result of an impulse from the statistical machine, to allow a spring to swing the plate into card-diverting position. During the downward movement of the card, the opposite edge 17 is engaged by the teeth of toothed wheels 33 secured on the shaft 19 to ensure that the card is fed between rollers 18, 34.
