Title: Improvements in or relating to the coating of the interiors of hollow articles with polythene compositions
IPC: B05D1/30
Filed: 1943-06-25
Abstract: 566,745. Polythene coating. WORRALL, G. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 25, 1943, No. 10287. [Class 95] A heated hollow article containing a melted composition comprising mainly normally solid polythene is inverted and the excess polythene drained out, leaving a coating of the composition on the inner surface of the hollow article. 5-10 times more polythene is melted than is to form the lining. It is preferred to shut out air during the melting operation by employing a cover, and during the draining operation by resting the inverted article on a tray. The hollow article may be a metal drum. The temperature of heating mentioned is 140‹ C. Instead of polythene alone, minor proportions of dyes, pigments, fillers and/or modifying agents, e.g. polyisobutylene, may be used in conjunction with polythene. Specifications 544,359 and 551,339 are referred to.

Title: Railway vehicle weighing system
IPC: G01G19/04
Filed: 1955-04-07
Abstract: 768,601. Electrical weighing systems. WESTINGHOUSE AIR BRAKE CO. April 7, 1955 [April 13, 1954), No. 10297/55. Class 40 (1). The track rail of a vehicle weighing system is associated with means arranged to vary. its impedance in proportion to the weight of a vehicle as it passes over the rail and so to vary the input signal to an electrical circuit, including relay means responsive to the impedance change and adapted to register into which one of several ranges the impedance change and therefore the weight of the vehicle jacks. As described, the system is used to control the application to a truck moving over a rail of a braking force varying with the weight of the truck. The track rail has mounted thereon an inductance 11 so that its impedance varies with the weight of the truck as it passes thereover, the inductance being in series with the windings 14, 16 and 18 of differential relays. Current is fed to the other windings 15, 17 and 19 of these relays through variable resistors 20, 21 and 22, each of which has an effective resistance about equal to the impedance of inductance 11 when the rail is undeflected and a temperature-resistance co-efficientsuch as to cancel out any impedance change in inductance 11 by temperature variation. By this arrangement, the excess voltage applied to the windings 15, 17 and 19 varies with the impedance of the inductance 11 and so the contact 23, 24 or 25, which is operated by its associated relay, depends upon the weight of the truck.

Title: Combined fuel and air admission device for oil explosion turbines
IPC: F23R3/28
Filed: 1928-04-05
Abstract: 288,321. Holzwarth, H. April 5, 1927, [Convention date]. Cylinders receiving liquid fuel.-A fuel injection device, for the explosion chamber of a turbine, worked by combustion products, comprises an air-charging valve which delivers a conical or cylindrical jet of air, into which the liquid fuel is sprayed. The air valve comprises a member f which is seated by a spring m on an annular casing d which receives its air supply through a connection b. An air guide e may be divergent, cylindrical or comprise a perforated cover plate; the fuel passes down a bore h in the valve stem and a non-return valve i to a nozzle k which may be transverse to the air stream. The air valve is opened by the fluid pressure of oil acting on a plunger l, the oil being supplied periodically through a pipe line n<1>, n by a rotating member p, Fig. 2, the centre q of which is connected to the source of pressure oil; a connection r to the atmosphere allows the valve to close again. The fuel pump u supplying fuel through a pipe line o<1>, o is driven by a cam t, moving synchronously with the member p, a return valve x, connected to the governor, being provided to regulate the supply. The spring m may be omitted, the air being arranged to act on the plunger l to close the valves as shown in Fig. 7. This Figure also shows a valve f<1>, which is opened by fluid pressure of oil in a chamber z, to admit scavenging air from a chamber b<1>; the valve f<1> in addition to the valve f may be closed by spring-pressure.

Title: Circular indexing mechanism
IPC: B23F23/08
Filed: 1938-04-05
Abstract: 513,688. Indexing mechanism. COVENTRY GAUGE & TOOL CO., Ltd., HARLEY, S. J., and OLAH, G. April 5, 1938, No. 10362. [Class 60] [Also in Group XXII] An indexing mechanism, particularly for use in a machine for cutting or grinding helical surfaces comprises an index locking - finger carrier b, a clutch member e having a variable oscillatory motion and coacting with another clutch member d connected to the index platecarrier a, and a cam c which is oscillated to engage and disengage alternately the index finger and the clutch members. The index-plate carrier a coupled to the work driver by a coupling m carries a number of index plates a<1> having teeth of different spacings and is connected by gearing i to the clutch member d. A drum b' forming part of the carrier b of the index finger b<2> is connected by steel tapes f<1> to a member f which may be moved transversely to impart a rotary movement to the work through the carrier b and the indexing finger, such movement being independent of the normal indexing movement. The index finger b', normally spring- pressed into engagement with one of the index plates, is connected by a link b<4> with roller coacting with a disengaging part c<1> of cam c. The clutch member e carries a lever e' fitted with a contact piece e<2> normally spring urged into engagement with a groove in the complementary clutch member d but lifted from such engagement when required by a cam portion c<2> engaging a roller e'. A hydraulic cylinder g<1> mounted in the member f actuates a rack g<3> engaging a gear c' on the cam member c. Another hydraulic cylinder h' in the member f actuates a rack h' engaging a gear e<5> on the clutch part e. Other means may be used to operate the racks g' and h'. On the down stroke of rack g<3> the gear c' is rotated anti-clockwise. During this movement, the cam c<2> leaves the roll e<4> and allows the part e' to lock the clutch parts d, e. During further angular movement of the cam member c the cam c<1> disengages the index finger b'. On downward movement of rack h' the rack rotates gear e<5>, and the part d. This movement, depending on the stroke of the rack, is communicated through gearing i to the work piece. The rack g<3> then returns, so reversing the gear c' and moving the cam c' so that the index finger re-engages. Also on further movement the cam c<2> disengages the parts d, e. On return of rack h' the member e returns to its original position with the clutch disengaged so that no work movement occurs. The phases of movement of racks g' and h' may be changed to give an indexing movement in the opposite direction. The additional movement which may be imparted to the work through the member f for cutting spiral flutes or for fine setting of the work may be obtained from an adjustable sine bar q actuating a counterbalanced vertical slide t. During the table movement the slide t is moved vertically by the sine bar and this movement is transmitted through a rod u with micrometer screw v to the member f. By adjusting the screw v a fine angular adjustment of the work may be obtained.

Abstract: 1451103 Discharge from aircraft ML AVIATION CO Ltd 28 Feb 1974 [5 March 1973] 10474/73 Heading F3C An ejector release unit for releasing and ejecting a store from an aircraft comprises a releasable latching mechanism which, in use, supports the store, and a pair of cartridgeoperated telescopic ejection guns 3, 4, the releasable latching mechanism having hooks 1, 2 which are located between the guns 3, 4 and having hooks 17, 18, the guns 3, 4 being located therebetween. The hooks 1, 2 are operated by a central toggle linkage comprising a lever 10 which is engaged at 12 by'a piston 16, pivoted by a shaft 11 and acted on at 13 by a compression spring 14 which tends to rotate the lever 10 in a clockwise direction. When the piston 16 is operated the lever 10 is rotated in an anticlockwise direction to cause collapse of the toggle linkage and a lever 9, which is connected at 13 to the lever 10 and is connected to the hook 2, moves the hook 2 to the left to release the load. At the same time a link 8, which is connected to the link 10 at 12, moves the hook 1 to the right, to release the load. An arm 19 is fixed to the shaft 11 and pivoted to a link 20. The link.'20 is connected to an arm 22 which is mounted on a shaft 23 to which is fixed one of a pair of links 24 constituting a toggle holding the hook 18 in its operative position. Consequently when the central toggle linkage collapses and the link 9 moves to the left, the link 20 also moves to the left, thus turning the shaft 23 in an anti-clockwise direction and with it one link 24. This causes the toggle to collapse and release the hook 18. Simultaneously the hook 17 is released.

Abstract: 541,795. Pump relief valves. TOWLER, J. M., and TOWLER, F. H. June 20, 1940, No. 10604. [Class 135] In an automatically acting pressure relief valve for the delivery main of an oil or other liquid pump, the pumped liquid has constant access to the two sides of a differential piston e, simultaneously, the liquid pressure on the larger piston area tending to open the plunger valve a against the liquid pressure on the lesser piston area combined with the pressure of a spring l, and the opening of the valve produces a reduction in the pressure of the liquid acting against the lesser piston area relatively to the pressure of the liquid acting against the larger piston area, whereby the effective pressure tending to open the valve is thereby increased. The plunger bar a is operatively connected to the piston e and has a normally closed orifice which when opened permits liquid to flow therethrough from the interior of the piston cylinder on the side of the piston of lesser area. Preferably the relief outlet comprises a constricted passage which is closed at one end and formed by a helical groove c on the exterior of the plunger a over a portion of its length. Alternatively, the relief outlet may be formed by an axial passage in the plunger with radial holes or slots at both ends for the inlet and outlet of the liquid. The pressure liquid passes to the two sides of the piston e through orifices j, k in the piston cylinder f.
