Title: Improvements in and relating to gas producers
IPC: C10J3/30
Filed: 1929-07-23
Abstract: 337,005. Galusha, A. L. July 23, 1929. Charging apparatus for gas producers comprises a feed-hopper 26 of large size, e.g. of sufficient capacity for a full days' fuel supply, which is elevated above the producer 15 to provide ample head room for operatives on the working platform 59 and from which the fuel passes by gravity to the producer through a number of vertical shoots 30. The hopper 26 communicates with a superposed storage bin 29 through an aperture controlled by a valve 28, similar valves 32, 33, 34 being provided to shut off the shoots 30 from the hopper 26 when the latter is being recharged from the bin 29. The shoots themselves are of sufficient capacity to maintain the fuel supply to the producer during this recharging period. The shaft on which the valve 28 is mounted is provided with segments which, by engagement with segments on the shafts of the shoot valves 32, 34, prevents opening of any of the latter valves while the valve 28 is open and also opening of the valve 28 while any one or more of the shoot valves is open. The valves are manually operated either by handles permanently secured to the shafts or by a detachable crank 70, Fig. 1, adapted for engagement with the lower shaped ends 61 of the shafts which project below the bearing plate 62. Distributing nozzles 35, having lateral branches a, b, c, Fig. 3, are telescopically mounted in the lower ends of the shoots 30 to provide an adjustment of the fuel level in the producer and consequently of the size of the gas-collecting space 18. A roof or shelter 64 for the protection of the operator on the platform 59, is secured to the feed-hopper 26. Specification 2917/00 is referred to.

Title: Improvements in or relating to mine car track retarders
Inventor: MAGILL JOHN ANGUS
IPC: B61K7/08
Filed: 1955-08-05
Abstract: 810,124. Track brakes. COAL INDUSTRY (PATENTS) Ltd. Sept. 14, 1956 [Aug. 5, 1955], No. 22630/55. Class 103 (1). In a mine car track retarder of the kind which is fixed by the track, a frictional retarding element is resiliently urged into engagement with passing mine cars by means of an inflatable bag. The embodiment shown in Figs. 2 and 3 illustrates a framework 4 to which are secured rails 1 for mine cars. Also supported by the frame 4 is a housing formed by members 31, 39, 40 carrying a brake-shoe 17 comprising a length of channel 171 to the limbs of which is welded a plate 172. A pneumatic bag 19 is located between the plates 40 and 172 which, when expanded by compressed air supplied to inlet pipe 35, forces the brake shoe 17 towards the mine car such that the friction lining 22 attached to the brake shoe engages a mine car retarding bracket 23. When there is pressure in the pneumatic bag 19, rubber blocks 34 bonded to arms 31 yield so that the brake shoe 17 moves outwards towards the mine car retarding bracket 23 and the brake shoe 17 is retracted by means of the resilient rubber blocks 34 when the pneumatic pressure is released. The bag 19 absorbs most of the longitudinal force on the brake shoe by means of bolt 32 abutting against plate 37 so that the bag 19 is compressed longitudinally in one direction of rotation, its end plate 45 abutting against bolt 33. Should motion of the mine car be in the opposite direction bolt 43 compresses bag 19 against the bolt 42 such that very little of the longitudinal force is absorbed by rubber blocks 34. Alternative embodiments are described in the Specification wherein the resilient means for returning the brake shoe to its inoperative position comprises spring means. Another embodiment discloses a brake shoe arrangement carried by pivoted links which has a servo-action obtained by the energy of the car assisting the action of the retarder by forcing the shoe further towards the mine car.

Title: Improvements in and relating to means for preventing the skidding of vehicles
IPC: B60B39/04
Filed: 1931-08-11
Abstract: 388,059. Vehicle sanding-apparatus. BUTLER, W. J., 67, Sefton Avenue, Mill Hill, and TIPPER, W. R., 385, Rotherhithe New Road, both in London. Aug. 11, 1931, Nos. 22660 and 29487. [Class 103 (iii).] In sanding and like appliances for vehicles, sand or the like is directed through shoots from a sand reservoir in predetermined quantities on to or in front of some or all of the vehicle wheels by means of feeding-devices operated by, or independently of, the brake pedal, or handbrake lever, or both, the feeding-devices being left after braking in a condition to deliver a further quantity of sand when the brake is next applied. The feeding-device, Fig. 3, comprises an upper shutter f normally open and a lower shutter h normally closed, the shutters being operated by levers m, n, o, k connected by a spring t and a slotted link p. The threearmed lever m, n, o is connected through a rod u to an operating-lever v, Fig. 5, having a projection x that may be swung into the path of the brake-pedal y or lever, and may be held in its two positions by a fixed spring 4 engaging recesses 6 in its surface. In operation a pull on the rod u opens the shutter h and, after some sand is ejected, the shutter f gradually closes under the action of the spring t. Sanding- devices on opposite wheels may be operated simultaneously by the rod u of each device being connected to one end of a cross-shaft 10, Fig. 2, connected to the lever v by a rod 7. Modified forms of shutter feeding-devices and operating means are described differing only in constructional details from the above. In one form for preventing operation of the sanding- devices when the brake is applied, a forked lever 47, Fig. 11, may be moved to engage a projection on a rod 45 operatively connected to a feeding-device and spring-connected to the brake-rod 43. In a modification in which the shutters are operated by a cable, both shutters may be retained partially open to allow a small stream of sand to be ejected whilst, for example, the vehicle is ascending or descending a hill. In another form the feeding-devices comprise rotatable drums 27, Fig. 9, each having compartments 28 for transferring sand from a reservoir 24, Fig. 7, to shoots 29. The drums are rigidly mounted on a shaft 31 journalled in housings 26 fixed to the reservoir, the shaft 31 being connected by flexible couplings at its ends to friction wheels 33 mounted on the ends of a shaft 35 which, when rotated positively or by a spring under the control of the lever v, Fig. 5, forces the wheels 33 into contact with the road wheels 6, thus rotating the drums to deliver sand. The shaft 31 may be rigid throughout its length and an idle roller may be interposed between each wheel 33 and its road wheel.

Title: Improvements in the manufacture of laminated glass
IPC: B32B17/10
Filed: 1936-08-18
Abstract: 480,255. Compound glass ; presses; filtering. TRIGGS, W. W. (Hercules Safety Glass Co., Ltd.) Aug. 18, 1936, No. 22703. [Class 140] [Also in Group I] Laminated glass is made by imposing an uncoated glass sheet upon a sheet of glass carrying a dried coating of plasticized gelatine while immersed in a neutral water-free liquid miscible with gelatine and having no chemical action thereon, pressing the composite structure in a heated press, and sealing the edges, e.g. with bitumen. The gelatine is plasticized with, for example, glycerol, a glycol such as ethylene glycol, or glycol-boriborate, and the neutral liquid may be a glycol such as diethylene glycol. The gelatine coating on the glass is dried by means of heated air. The composite structures to be pressed are placed between hard rubber sheets 45, Fig. 6, on trays 20 which are pushed along guides 21 into the press, pushing out, on the other side, a tray containing laminations already pressed. The glass is pressed between a fixed waterheated platen 11 and platens 17 urged towards it by inflatable bags 19. Alternatively the glass may be placed in vertical trays and pressed between vertically arranged platens. To facilitate removal the trays are counterbalanced by weights on the ends of ropes passing over fixed pulleys. On removal from the press, the glass is immersed in hot water to remove gelatine from the edges of the glass, and the channel produced is dried and filled with heated bitumen supplied under compressed air pressure to a nozzle 40, Fig. 4, having a guide wing 42 which slides in the channel and a tail-piece 44 to press down the bitumen. The gelatine solution to be applied to the glass may be filtered by placing it in an airjacketed vessel 1, Fig. 1, and forcing it upwards through a filtering layer of wool felt 5 retained by a ring 9 on a conical member 4, and out through pipes 3 and 10 by compressed air admitted at 6.

Class 38 (v) A shock-proof contactor comprises a pair of arms 15, 15a mounted on parallel shafts 14, 14a and carrying E shaped armatures 18, 18a adapted to move together into engagement on energization of the coil 10. The arms also carry contacts adapted to engage each other, Fig. 3 (not shown) and are biased by a tension spring 25 arranged between arms 19, 19a fixed to bars 16, 16a fixed to the arms 15, 15a. In the form shown the bars 16, 16a each bridge two bars 15 or 15a. The arms 15 and 15a are also linked by links 33, 33a to a rotary member 31 which compels the arms to move either towards or away from each other simultaneously. In the event of shock, both arms try to move in the same direction but are prevented by the member 31 which is pressed against its seating and offers frictional resistance to movement; Limitation of movement is provided by a slotted link 28 or in a modification, Fig. 4, by the members 16, 16a being fixed to members 37, 37a connected by slotted links 35, 36. In this last arrangement auxiliary contacts are made and broken by pins 41, 42 in the slots 39, 40 engaging or leaving the parallel legs of contacts 43, 44. Specifications 536,696 and 580,279 are referred to.

Title: Method and machine for packaging or wrapping of articles
IPC: B65B31/04
Filed: 1946-08-01
Abstract: 615,368. Packing ; packages. SALFISBERG, L. L. Aug. 1, 1946, No. 22949. Convention. date, Aug. 10, 1945. [Class 94 (i)] In apparatus for packing tablets or compressed granular materials in a partial vacuum within a flexible package, two strips 1, 2 of flexible air-impervious material are fed between rollers 4, 5, the roughened surfaces of which compress the strips together and seal them except where the surfaces of the rollers are relieved as at the edges 13, the recesses 8 and the channeis 11. Thus each so formed compartment 17, into which a tablet 14 has been inserted during the sealing operation, is connected to the unsealed outer edges by a passage 19. Next, the air is exhausted from each of the compartments 17 by a device comprising grooved pulleys 21 on which rotates an endless rubber belt 20 having a convexly curved outer surface 22 in which is a groove 24. Part of this belt runs between the unsealed edges of the strip and an air-tight joint is formed between the belt and the strip by nozzles 28 which lead back to an exhaust pipe 26. Between the nozzles 28 are mounted rollers 29 having circumferential end flanges 30. These flanges seal the passages 19 after the air has been withdrawn. On leaving the air-exhausting device, the combined strip is subdivided in any suitable manner. To exhaust as much air as possible from the compartments 17 the recesses 8 may be filled with rubber. In the case of granular material the material is first compressed into tablets and sealed as above, the tablet being subsequently crushed within the packet. The unsealed edge portions 39 of the package provide means for tearing the package open and one edge portion extends beyond the other. The compartment may be circular, polygonal or pentagonal in shape.

Title: Bulky yarn and production thereof
IPC: D02G1/16
Filed: 1971-04-19
Abstract: 1310203 Bulky yarn E I DU PONT DE NEMOURS & CO 19 April 1971 [4 March 1970] 23108/71 Headings D1F and D1W A bulky yarn of at least 30 crimped entangled continuous thermoplastic filaments is characterized in that laterally-orientated filament loops penetrate within the yarn and bind other filaments of the yarn in place. The filaments are permanently crimped so as to provide partially recoverable stretch of 8% to 40% when the yarn is subjected to a load of 0.1 gm/denier. The degree of filament entanglement is such that there is at least 5% stabiliszed yarn bulk when the yarn is subjected to a load of 0.1 gm/denier and that there is less than 8.9 cm mean separation distance of filaments groups under a 454 gm load in the lateral pull-apart test with a standard deviation of individual determinations of less than 0.5 times the mean sepearation distance for ten determinations along the length of the yarn. The yarn is substantially free from any twist or surface filaments that wrap tightly around the yarn causing a decrease in yarn diameter. The yarn may be prepared by passing a true-twist-free and entanglement-free bundle of at least 30 filaments of thermoplastic polymer to a nozzle, and supplying to the nozzle a heated fluid such that the yarn is subjected to turbulent action. The heated fluid exerts a forwarding action on the yarn and causes the filaments to become entangled. The yarn is withdrawn from the nozzle at a speed which is less than the feed speed such that the overfeed is at least 20%. A yarn finish may be applied to the yarn prior to feeding to the nozzle, the finish preferably being a liquid having a viscosity of less than 5 centipoises at 150‹C and a sufficient boundary friction coefficient for the yarn to retain a specified degree of filament entanglement in subsequent processing steps. The process may be carried out in the apparatus shown in Fig. 1 wherein filaments 10 pass successively to a preheat chest 11, feed rolls 12 and 13 and fluid jet device 14. The bundle of filaments, in a splayed open configuration on emerging from the jet device is removed sideways to rolls 15 and 16. This sideways removal serves to collapse the splayed configuration. The bundle is eventually packaged at wind up device 22. The construction of the fluid jet device is shown in Fig. 2. Yarn passageway 25 has an entrance 26 and a venturi-shaped exit 27. Superheated steam or air introduced to chamber 28 passes through channels 29 to a main pair of opposed jet stream conduits 30 and 31. Additional pairs of smaller opposing conduits 32 and 33 which intersect the yarn passageway in the same plane as 30 and 31, are also provided (Fig. 3, not shown). The process is particularly applicable to polyamide filaments.
