Title: Open-end or break-spinning machine
IPC: D01H4/12
Filed: 1972-08-17
Abstract: 1357503 Drive and brake arrangement for an open end spinning machine WILHELM STAHLECKER GmbH 17 Aug 1972 [18 Aug 1971] 38470/72 Heading DID [Also in Division F2]  A drive and brake arrangement for an openend spinning machine comprises a brake lining 11 which can be pressed against a rotor shaft 2, and a frictional drive with means to apply the drive against the rotor shaft 2. The brake lining and frictional drive are arranged on a system of levers connected so that the force applying the brake lining against the rotor shaft 2 is at least partially transferred to the means applying the frictional drive so as to interrupt the drive. As shown, the shaft 2 is braked by pivoting a brake arm 12 downwardly. After the brake 11 engages the shaft the arm carrying the drive belt pressing roller 6 is swung upwardly to release the belt 5 from the shaft 2. In Fig. 3 (not shown), after the brake arm has engaged the shaft 2, the friction drive roller 19 is pivoted upwardly away from the shaft 2. The drive roller then engages a brake (25) to reduce its speed. In Fig. 5 (not shown) the brake lining 39 is pivoted against shaft 2 and thereby moves the drive roller 19 upwardly with a camming action. In Fig. 6 (not shown) the brake arm 12 is first swung down onto shaft 2 and then its pivoted end causes the drive roller to lift away from shaft 2 against brake 25. The drive roller 19 is releasably held in bearings 20 by spring plate 49. In Fig. 7, (not shown) brake arm is swung downwardly onto shaft 2 whilst compressing spring 52. Continued movement of the brake arm causes the arm 7 carrying the drive roller to pivot upwardly. The drive roller may be mounted on an electric motor. In Fig. 8 (not shown) the scissor like arrangement of the brake arm 12 and drive roller supporting arm 7 is such that band 57 operates the brake before pivoting the pressing roller or drive roller 6 off the shaft 2. In Fig. 9 (not shown) the tension in operating band or rod 59 retains the pressing roller on the belt 5 and the brake arm 12 inactive. Upon release of the band 59, spring 64 causes the brake to bear on shaft 2, then the pressing roller 6 to lift off the belt. In Fig. 10 (not shown) the handle 76 slides the brake 79 onto shaft 2, before causing the sloping surface of the brake lining to lift the pressing roller off shaft 2. The free end of the brake arm can be actuated by an eccentric wheel.

Abstract: 1,127,441. Vehicle unloading ramps. HAWKER SIDDELEY AVIATION Ltd. 23 Sept., 1965 [23 Sept., 1964], No. 38799/64. Heading B8E. Freight loads are transferred from one level to another such as in unloading an aircraft as described by placing two rails 16 on a ramp sill 17 further apart than the maximum width of a load 14 or its carrying platform 15 to which wheels 21 are temporarily attached at the end which leads as the load is lowered on the rails. The lowering or raising is effected by a winch cable 20 attached to the non wheeled end of the load which as it is moved free of the sill 17 can be lowered down through the rails 16. Roller conveyers are provided on the cargo floor 12 and on the lower door 24 which forms a continuation during loading and heavy duty rollers 22 are mounted on the ramp sill 17 to assist the non-wheeled end of the load to pass over it. Roller conveyers 19 may be provided on the ground under the rails 16 so that as the load is lowered it rests thereon.

Title: Recording devices
IPC: G07C3/00
Filed: 1957-12-13
Abstract: 887,912. Recording-apparatus; speedometers. CASIGLIA, F. Dec. 13, 1957 [Dec. 14, 1956; Dec. 22, 1956], No. 38935/57. Classes 106 (3) and 106 (4). A temporary recorder comprises a transparent rotatable disc 13, a stylus 20 bearing against the disc and movable in a direction transverse to the direction of movement of the disc and a reservoir of finely-divided powder, applied as a layer of dust to the disc anew in each revolution thereof as it comes into contact with the reservoir and removable by the stylus upon relative movement to leave a visible trace on the freshly coated disc. The disc 13 forms the front closure of a drum 12 rotatably mounted on a fixed bearing 11 which carries a stationary support 16 within the drum 12. The stylus 20 is carried by a pivoted axle 18 to which is fixed a sector 19 meshing with a toothed wheel 4 on a spindle 9 journalled in the bearing 11 and deflected against the action of a spring 3 to an extent proportional to the speed of rotation of a vehicle driven shaft 1. The drum 12 is rotated at a speed proportional to the speed of the vehicle through reduction gearing including a toothed wheel 14 meshing with external teeth on the drum 12 and an externally-threaded brass cup 5 secured to the shaft 1. The reservoir of powder is contained by the drum 12. As the drum rotates anticlockwise, Fig. 4, any powder adhering to the disc 13 is removed by a sponge buffer 22 carried by an axially-extending wing 23 of the support 16. The powder falls and tends to be carried towards the right, the wing 23 preventing any from spilling on the toothed wheel 4 and sector 19. In another embodiment the stationary support within the drum also carries a number of electromagnets each controlling a subsidiary stylus to record the operation of auxiliary devices such as turn indicators, brakes, lights and horn. Suitable powders are talcum, metal and graphite and greater adhesive power may be achieved by incorporating a finely-powdered acid fat, e.g. stearic acid or oleic acid, or a finely-powdered wax with similar characteristics, it being essential that this added material should have a melting-point high enough to ensure that the powder remains dry at normal working temperatures. Phosphorescent or fluorescent powders may also be added. The drum may be driven at constant speed instead of by the vehicle. The stylus 20 has a fibre drawing point.
