Title: Improvements in, or relating to, aerial bombs
IPC: F42B12/20
Filed: 1933-07-28
Abstract: 406,574. Projectiles. BORM, P., 37, Rivage, Herstal, Lez Liege,. Belgium. July 28, 1933, No. 21217. Convention date, July 28, 1932. [Class 9 (i).] Relates to dummy or practice bombs intended to be dropped from aircraft and comprising a heavy body 1 and a winged tubular tail 5 containing a signal cartridge or the like 14 fired on impact. According to the invention, the winged tail is attached to the body by a weak connection such as a pin 9, and the wings 6 are bent laterally as at 17 to provide resistance to penetration of the ground, with the result that on impact the pin 9 is sheared and the tail remains at the surface while the body 1 penetrates into the ground. The cartridge 14 is fired by moving forward against a spring 13 on to a firing-pin 12, a safety 15 having been removed before the bomb is dropped. The nose 2 of the body 1 is provided with a transverse hole 3 for suspension purposes, and its rear end with a tapped hole 10 for the insertion of the screwthreaded end of a rod to recover the body from the ground.

Title: Method of providing rails with water-repellent and oil-repellent surfaces
IPC: B61K3/02
Filed: 1955-07-22
Abstract: <PICT:0799787/III/1> A method of providing the wearing surface of rails with a coating which is water-repellent and oil-repellent comprises employing a locomotive to apply liquid silicone compounds or liquid fluorinated organic compounds, e.g. perfluorobutyric acid to the wearing surface through nozzles or wipers connected by pipes to supply tanks.  The rails may be given a preliminary cleaning by spraying them first with a petroleum base emulsifying detergent, then with an alkaline detergent solution to remove the emulsifying detergent and finally applying a heater to the rails to dry the wearing surface.  As shown, a locomotive 2 is provided with a container 1 having a feed line 3 terminating in a nozzle 7. Fluid from the container 1 is atomized by entrainment with an air stream. alternatively fluid from a container 11 may be supplied to a pad 14 in contact with the rail or allowed to drip over the rail.  A flame heater 23 is provided for drying the rails.  Before the flame heater is used, the rails may be sprayed with steam to remove the emulsifying detergent solution and also sprayed with steam after the rails have been sprayed with an alkaline detergent solution.

Patent GB-831488-A (GB)
Title: Improvements in or relating to wringers
Inventor: ETTEN NICHOLAS LAWRENCE
IPC: D06F45/04
Filed: 1956-07-13
Abstract: 831,488. Wringers. CHAMBERLAIN CORPORATION. July 13, 1956, No. 21764/56. Class 138 (2). A wringer comprises upper and lower frames 48, 10, wringer rollers 55, 15, and a manually operable arm 58 pivotally mounted (at 59) on the upper frame and forming a part of a non- locking toggle mechanism whereby movement of the arm in one direction serves to apply pressure to urge the rollers together, and the arm 58 is retained in its pressure-applying position by means of a hook 66 on the arm arranged to engage a pin 68 on the lower frame. A link 62 is pivoted at 63 to the arm 58 and at 64 to the lower frame 10. The hook 66 is pivoted at 67 to the arm 58 and biased by a spring 70 into engagement with the pin 68. Release of the hook 66 is effected by downward movement of a manually operated member 71 which engages an arm portion 69 of the hook structure 66. When the hook 66 and arm 58 are released a spring 56 carried by the frame 48 causes pivotal movement of the frame 48 about a pair of lugs provided on the frame 10 and passing through openings in the frame 48 (Figs. 2A and 2B, not shown). This upward movement of the frame 48 allows a spring 45 to disconnect the drive to the lower roller 15. This spring 45 is connected between part of the frame 10 and a member 40 pivoted at 42 and provided with inwardly directed portions adapted to engage a shoulder on a coupling 17. The coupling 17 has slots adapted to receive pins on the shaft of the lower roller 15 and a drive shaft 22 respectively. In the pressure applying position of the upper frame 48 a downwardly depending fixture 51 carrying one end bearing for the roller 55 holds the member 40 in the full line position shown and allows a spring 38 to bias the coupling 17 to the driving position. Upon release of the top frame and consequent removal of fixture 51, spring 45 forces the coupling 17 out of driving engagement with the pin on the roller shaft. Thus rotation of the lower roll is automatically arrested when the roll pressure is released. The coupling 17 permits limited vertical adjustment of bearing blocks (as 14) for the roller 15 by means of screws 16. Specifications 608,509 and 624,682 are referred to.

The insert 12 may be secured by adhesive. In a modification, Fig. 7, the insert 12A has a nut 30 and the anchor disc 24A carries a bolt 13A. If the leg is required to be inclined a wedge is inserted between disc 24 and frame 20.

Abstract: 1412296 Mechanical interrupters NSF Ltd 10 May 1973 [10 May 1972] 21804/72 Heading H1N Motor driven timing apparatus comprises a driving assembly 14, 15 and a driven assembly 16 including at least one set of contacts actuated by a rotary cam, and indexing means 40 comprising a notched cam 41 co-operating with a resiliently-loaded follower 42 to establish a plurality of preferred positions for said rotary cam, the arrangement being such that increasing torque applied by the driving assembly to the driven assembly produces progressive elastic deformation of a resilient member whereby rapid stepping of the driven assembly is produced by reslient recovery of said deformation. As shown, contact sets 11 are actuated by cams 12 carried on a shaft 13 which is coupled to motor 14 via gearbox 15. In the embodiment of Fig. 1 the resilient member (whose deformation causes stepping) comprises two rubber or synthetic elastomeric grommets 19 by which the plate 18 is mounted to assembly 16, but in the embodiment of Figs. 5 and 6 (not shown) the driving assembly 14, 15 is rigidly mounted to assembly 16 while the camshaft with indexing means 40 is coupled to the output shaft of gearbox 15 via an elastomeric body (56) whereby the driving torque is transmitted intermittently.

Each distributer may comprise a stationary upper plate 22 having a central inlet opening 26 and a pendant side wall around half its circumference and located above a rotary plate 25 provided with curved radiating vanes 24 which do not meet at the centre. The direction of discharge is regulated by moving a slide 28 around the distributer. Compressed air or other forced draught may be employed to assist the distribution. The rotary plates 25 may be geared together and driven from the vehicle gear box through a side shaft, bevel, spur, and chain gearing and a clutch. An auxiliary gear box may be provided to transmit different speeds. The elevator 15 is driven from the side shaft through chain gearing.

Title: Booster apparatus for an assisted hydraulic system with an energy accumulator device
IPC: B60T13/14
Filed: 1973-05-10
Abstract: 1400677 Brakes; boosters DBA SA 10 May 1973 [1 June 1972] 22373/73 Headings F2E and F2F  A booster device 10 located between a master cylinder 12 and brake cylinder 14 is connected to a spring loaded energy accumulator 26 by means of a linkage assembly 24 operative to provide a boosted pressure to the brake cylinder 14 when the master cylinder pressure is above a predetermined level. Below this level fluid passes directly to brake cylinder 14 via a non- return valve 126 and passes from an inlet 18 of a booster 16 to an outlet 20 via a chamber 42, a clearance 46 between a rod 28 and a drive member 40 and a chamber 44. Above the predetermined level a piston 34 is moved leftwardly against the bias of a spring 60 entraining, through a sleeve 36, rod 28 a shoulder 50 of which engages a seal 48 to close communication between chambers 42 and 44. Rod 28, being coupled to accumulator 26 via a bell crank lever 74 and link 86 of assembly, causes a pivot 84 between link 86 and lever 74 to traverse the connecting line between pivots 88 and 96 respectively of lever 74 and link 86. A roller 90 is then caused to move along a surface 92 of booster housing 22 under the bias of the spring 104 of accumulator 26 whereby a force is applied to rod 28 via linkage assembly 24 thereby causing pressurization of fluid in a chamber 44 through driving member 40 to provide a boosted pressure to brake cylinder 14. Reverse flow via a line 124 to the master cylinder is prevented by non-return valve 126.  The device is initially set by a bolt 116 which co-operates with a nut 118 fixed to the booster housing 22 and which urges rod 28 to the right by wall of a ball 120 fixed to the rod by a sleeve 122.
