Title: Improvements relating to friction clutches
IPC: F16D13/71
Filed: 1933-07-01
Abstract: 419,834. Friction clutches. BORG & BECK CO., Ltd., and BOUGHTON, E. B., Brock House, Langham Street, Regent Street, London. July 1, 1933, No. 18740. [Class 80 (ii).] The radial levers 8 for withdrawing the spring-loaded pressure plate 3 of a friction clutch are so mounted that, during operation, each lever executes, at one of its bearings, a rolling movement whereby a longitudinal translation is imparted to the lever, one or both of the other bearings being such as to permit this translation without rubbing or sliding. As shown in Fig. 1, wherein the levers 8 are adapted to be turned anticlockwise for disengagement, a floating pin 10 mounted in each lever rolls in an enlarged aperture 11a in a bolt 11, which is mounted in the cover plate 5 and is slidably supported in the plate 3. The rolling action is facilitated by forming flats 11b on the operative part of the aperture, or by forming this part of larger radius than the remainder of the aperture. The outer end of each lever is connected to a lug 3a projecting from the plate 3 by an encircling tension link 12 having knife edges bearing in a recess 3b in the lug 3a and in a curved socket 8d in the lever. Anti-rattle springs 7 are fitted between the cover plate 5 and the levers. Alternatively, a compression link 18, Fig. 7, may bear by rounded or knife edges between a curved socket in the lever and a lug 3d projecting from the plate 3, the link having extensions 18c which loosely engage in grooves in the lug 3d. Springs 16 may be provided to maintain the inner ends of the levers 8 in engagement with the actuating collar 9. In the form shown in Fig. 3, each lever has a rounded outer end. contacting with a flat face on a lug 3d projecting from the plate 3 and a compression link 13 with knife edges bears between the cover plate 5 and the lever. Projections 13a and 13b enter loosely into apertures in the plate 5 and lever respectively, and anti-rattle springs 14 are fitted between the actuating collar 9 and the cover plate. Where the levers are adapted to be turned clockwise for disengagement, enlarged apertures 22, Fig. 8, formed in lugs 21 on the plate 3, receive pins 25 mounted in the levers, struts 27 with rounded or knife edges being arranged between sockets in the outer ends of the levers and in the plate 3. If desired, knife-edged links may also be arranged between the inner ends of the levers and the actuating collar 9.

Title: Air-borne absorptive elements
IPC: G10K11/16
Filed: 1974-04-29
Abstract: 1421875 Sound-absorbing laminates A STANKIEWICZ [trading as DR ALOIS STANKIEWICZ CHEMISCHE ERZEUGNISSE] 29 April 1974 [30 April 1973] 18763/74 Heading B5N [Also in Division F2] An air-borne sound absorptive porous or non-woven fibrous layer 2, e.g. open-cell foam or mineral fibres, is overlaid by a non-woven thermoplastic fabric 3 which has been fused through part or all of its thickness to form a continuous, non-homogeneous thermoplastic film having an infra-structure characteristic of the disposition of the fibres in said fabric. As shown, a surface film 4 is formed, either before or after the layers are bonded. The layer 2 is fitted to a surface 1 to be insulated, e.g. part of an I.C. engine-compartment, before or after layer 3 is applied. The layers may be preshaped to match the surface. The layer 3 may be a polypropylene fleece and the film structure may be formed by heating under pressure; heavier pressure may be used to form depressions 6 for accomodating engine parts which are close to the compartment wall. The layers 2 and 3 may be bonded by adhesive 5, preferably at spaced areas. The fabric 3 may be sealed around the edges of layer 2 or of openings therein by adhesive bonding to the surface 1 where it abuts same, or by folding under layer 2 to form a packing which is then fused or adhered to both layer 2 and surface 1.

Title: Improvements relating to level indicators for liquids
IPC: G01F23/64
Filed: 1929-06-19
Abstract: 313,929. Caretta, E. June 19, 1928, [Convention date]. Indicators actuated by floats.-In liquid-level indicators of the kind in which a vertically moving member manipulated from outside is stopped when it engages a float, the float is capable of being looked directly on a guide, and the actuated member engages it by a simple thrust. A guide tube 2 is surrounded by a freely moving float 3 and is slotted at 4 to receive an arm 6 carried by the externally manipulated cable 5. When the projection 7 reaches the float, the latter is tilted and locked on the tube 2. The raising of the arm 6 immediately releases the float. In a modification, Fig. 2, the float 3 carries a roller 10 which extends into the guide tube 2 and the externally manipulated member consists of a plunger 11 which presses the roller 10 outwards and locks the float 3 on the guide 2. Another modification employs separate guides for the float and the member 11.

Abstract: 627,665. Spray-producers. CARBAJAL, F. S., and SUBI, J. R. July 15, 1947, No. 18877. [Class 69 (iii)] [Also in Group XXVIII] A liquid container 1 slides within a casing 2 which houses a spring 3 fastening a piston 5 against the container base. An air intake tube 6 leading from the casing top has its outlet end connected to the container top via a chamber 18, passage 16, chamber 9 and passages 14 in a cap number 7. A liquid discharge tube 8 has its outlet end fixed within a nozzle 11. Projections 23 on the case slide within longitudinal grooves 19 in the container during its reciprocation within the case, the alternating pressure which is thereby produced on the liquid surface pumping liquid in spray form through the nozzle 11. When not used the container is pressed within the casing to bring the projections 23 within the groove 20, the container being then rotated and locked in position.

Title: Improvements in or relating to steering gear for motor road vehicles
IPC: B62D5/06
Filed: 1929-06-24
Abstract: 335,539. Payne, M., and Clayton Dewandre Co., Ltd. June 24, 1929. Steering-gear; hydraulic and pneumatic transmission. - Comprises steering-gear in which engine suction or other fluid pressure is employed under the control of a valve connected to a lever arm, such as the drop arm 3, through the medium of a two-armed lever 5, which constitutes the sole connection between the lever arm and the member actuated thereby, and which is fulcrumed on the lever arm and connected at one end to a member 4 of the steering-gear and at the other end to the valve 12, the end connected to the valve being movable between fixed stops located adjacent the fixed fulcrum of the lever arm 3. In the construction shown the upper end of the lever 5 is formed with an eye which loosely embrace a pin 8 concentric with the pivot of the arm 3 and is provided with spring-pressed pins 9, Fig. 2, tending to keep the arm and the lever in line. The lower end of the lever is connected to the drag link 4 and also by a rod 10 to a power cylinder 11. The valve 12 controlling the cylinder 11 comprises a casing 14, Fig. 5, a central hollow plunger 20 connected by a link 13 to the lever 5 and having ground ends, and two spring loaded valves 17. In the neutral or central position shown in Fig. 5 the plunger 20 is not in contact with either of the valves 17, and the cylinder 11 is open to the atmosphere at both ends through pipes 27, grooves 18 in the valves 17, the hollow plunger, and a port 24. When the steering hand-wheel is rotated, the drop arm is moved, the lever 5 rocks slightly about its lower end and moves the plunger 20 which abuts against and opens one of the valves 17 and thus connects the corresponding end of the power cylinder to the engine induction pipe through pipe 27, valve 17, and pipe 25. The connection of that end of the cylinder to the atmosphere is cut off when the plunger abuts against the valve 17. The drag link 4 is thus operated and as soon as the drop arm comes to rest the lever 5, which has been following the drop arm, centres itself over the drop arm and the valve 12 is returned to the neutral position with the steering gear in the required position. A modified construction of valve is described in which the. member connected to the link 13 has valve faces beyond the outer ends of the valves 17. A constant-pressure vacuum valve may be provided between the induction pipe and the control valve, and, in order to enable, the servo action to be cut out when required, a valve may be provided which cuts off the device from the induction pipe and opens both ends of the power cylinder to the atmosphere. Two single-acting power cylinders may be employed instead of one double-acting cylinder. According to the Provisional Specification the steering-gear worm sector may be connected by parallel links to the drop arm, one of the links operating the valve controlling the power cylinder.
