Title: An apparatus in which a tow of continuous filaments is subjected to breaking and drafting in two zones to form spun yarn
IPC: D01G1/08
Filed: 1954-01-05
Abstract: 759,939. Stapling continuous filaments; drafting-arrangements. TAKAGI, T. Jan. 5, 1954, No. 270/54. Classes 120 (2) and 120 (3). In apparatus for the direct spinning of continuous filament tows by breaking and drafting in two zones, a travelling friction surface is interposed between the front and back breaking rollers in a manner to bend the tow and has a surface speed higher than that of the front breaking rollers. Tow from a spool 10 passes through a spreader device consisting of two stationary rods or rollers 14, 16 and a reciprocating roller 18 to back breaking rollers 20, 22, 24, between which it is guided by a leather apron 26. Between rollers 20, 22, 24 and front breaking rollers 27, 30 is located the friction roller 54 and between rollers 27, 30 and drafting rollers 40, 42 extends a drafting apron 32. When operating upon viscose filaments, the speed ratios of back breaking rollers, front breaking rollers and drafting rollers may be 1 : between 2.5 and 4: between 30 and 60. The linear speed of the friction roller 54 may be 65-130 times greater than that of the rollers 22, 24. A doctor blade 56 clears the friction roller 54 of fibres ; the latter may have a plain surface, or be leather covered, or fluted, knurled, or sawtoothed. Supply bobbins of tow may be located in a heating box to reduce the water content of the tow.

Abstract: 869,020. Toy pistols. ADRIAN & RODE G.m.b.H. Jan. 3, 1958 [Jan. 22, 1957], No. 328/58. Class 132(3). A nozzle loading multi-barrel toy pistol for explosive corks comprises a spring controlled firing lever 8 mounted on a common pivot 9 with striker levers 4, 5 having firing pins 3 pivoted to them, the firing lever having circumferentially spaced driver pins 11, 12 on opposite sides for engagement with the striker levers 4, 5 In the cocked position as shown in Fig. 1, springs 7 act on the striker levers 4, 5 below the pivot 9 to urge them backwards, but, on operating the firing lever, the driver pins pivot the striker levers in turn until the springs 7 act above the pivot 9 and urge the striker levers and their firing pins 3 forward to fire the corks one after the other. The end of the striker lever 4 projects to form a cocking handle 13 by means of which both striker levers 4, 5 can be cocked, a cross member 14 on the lever 4 engaging the striker lever 5. The driver pins may be staggered radially, the radial distance between each striker lever and the driver pins being so dimensioned that it lies only in the path of the driver corresponding to it.

Title: Improvements in and relating to vehicle power steering apparatus
IPC: B62D5/06
Filed: 1955-01-05
Abstract: 794,986. Fluid-pressure servomotor-control systems. THOMPSON PRODUCTS, Inc. Jan. 5, 1955 [Aug. 23, 1954], No. 357/55. Class 135. [Also in Group XXXI] In a vehicle power-assisted steering mechanism having a steering shaft 10 connected by a helical gear to a shaft 22 connected to the steering linkage (not shown) and extending transversely of the steering shaft 10 whereby manual rotation of the shaft 10 causes both rotation and axial movement of the shaft 22, axial movement of the shaft 22 actuates a valve element 32 controlling a fluid-operated motor which is connected to the shaft 22. As shown, the steering shaft 10 carries a helically-toothed worm 20 meshing with a sector 21 on the shaft 22 mounted by bearings 23, 24, 25 in a housing 13, the axial movement of the shaft 22 due to rotation of the shaft 10 being limited by abutment of the shaft 22 with shoulders 26, 28 on the housing 13. Secured to the shaft 22 by a rod 33 is the three-landed valve element 32, the shaft 22 and element 32 being centred by a spring 34. The element 32 co-operates with a valve housing 16 having conduits 15, 44 connected to the output and input, respectively, of a pump 14, the conduit 44 leading into the housing 13 and the housing 13 being connected by a conduit 43 to passages 41, 42. With the element 32 centred liquid from the pump 14 circulates back. The valve housing also includes conduits 17, 18 leading to a cylinder 47 having pistons 49, 50 carrying racks 51, 52 meshing a helical gear 53 on the shaft 22. Downward movement, for example, of the element 32 and shaft 22 causes the conduit 17 to be pressurized and the conduit 18 to be connected to exhaust, thereby moving the pistons 49, 50 outwardly in the cylinder 47. The outward movement rotates the element 32 and shaft 22 and also tends to move them upwardly in opposition to the downward movement due to the initial manual effort, thus giving the driver " feel ". A check valve 30 is provided between the conduits 15, 44, thus permitting circulation of fluid to allow manual steering should the pump fail. The element 32 may not be directly connected to the shaft 22 but may be operated thereby through a lever arm. Feel may be provided by incorporating hydraulically-actuated piston means associated with the element 32, the gear 53 and racks 51, 52 having straight teeth. Specification 757,558 is referred to.

Abstract: 150,595. Jackson, W. J. Mellersh-, (Allen Electrolytic Cell Corporation). Jan. 5, 1920. Cells; diaphragms; electrodes, supporting; connexions; alkalis and chlorine, obtaining. - A basket-shaped perforated cathode 24, unsubmerged in the electrolyte, is detachably connected with a fluid-tight joint to the lower edge of a free-board section 15 so that these parts, with the anode and the diaphragm lining the cathode, are supported by the edges of a tank 12 and may be removed bodily therefrom. As shown, the cathode 24 is bent over to form flanges 25, the gaps in the flanges at the corners of the cathode being filled by small square plates equal in thickness to the cathode and diaphragm together. A metal frame 30 beneath the cathode flanges is secured to the freeboard section 15 by bolts 31; the edge of the diaphragm makes the joint fluid-tight. The diaphragm consists of one or more strips of asbestos paper laid lengthwise on the bottom and over the end walls of the cathode, and sheets of asbestos which cover the side walls and overlap on the bottom, to reduce the permeability where the hydrostatic pressure is greatest. The edges of the diaphragm may be impregnated with chlorineresisting insulating-material. The anode is roughly of the form of an upright tube, in close proximity to the cathode. As shown, it consists of eight flat bars 33 joined by end pieces 38 and attached by carbon pins 34 to terminal bars 35. It is carried by the freeboard section 15, or rests on insulating cross-pieces 37 on the bottom of the cathode. Electrolyte is fed in through a well 18 and aperture 43. The tank 12 may be filled with oil. Packing material may be placed on its edge if hydrogen is to be collected.

Operation of the pump actuates the mushroom valve 123 admitting water to chamber 113; movement of valve 123 is transmitted by piston rod 22 to the annular piston valve 221 placing chamber 113 in connection with the foam chamber 112 by means of port 222 in piston 221 and port 231 in sleeve 23, which is manually rotatable to vary the proportion of foam admitted. The operation of the valves may be assisted by a cylinder 301, Fig. 6 (not shown) which is also connected to the suction side of the pump and has a piston 303 and a piston rod formed as an extension of the valve 221. In another embodiment, Fig. 8 (not shown) a hollow cylindrical valve 31 secured to and moving with the valve 123 replaces the piston 221. The valve 31 has an outlet port 313 to the suction chamber 113 and an inlet port 311 co-operating with a port 231 in the fixed sleeve 23. A spring 32 maintains the valve 123 on its seat; it is opened by the action of the servomotor 37 which is in connection with the suction side of the pump by way of the pipe 39.

The sublimate is recovered by this method partly as a solidified melt but mainly as crystals.  The current may be greater than 100 amperes and preferably is greater than 100 amperes and may be generated by ignitron circuits described in Specification 698,870, [Group III].ALSO:In a process of sublimation, deposit of the sublimate on the collecting surfaces or on other surfaces is removed by passing an electric current directly through the surface for periods of not more than 11 seconds duration whereby part of the deposit is vaporized and the remainder freed from the surface.  Preferably the current is of 10 amperes or more and may exceed 100 amperes and may be generated by the ignition circuits described in Specification 698,870.
