Title: Process and apparatus for the treatment of liquids
IPC: B29C48/76
Filed: 1968-03-29
Abstract: 1,208,074. Treating liquids with gases or vapours or liquids; polymerization apparatus; degassing liquids. 29 March, 1968 [13 April, 1967], No. 15241/68. Headings B1F, B1M, B1R, and B1X. [Also in Division C3] Apparatus for treating a liquid, e.g. by reacting it with another liquid or by contacting it with a gas or vapour, comprises a horizontal or nearly horizontal vessel 16 through which the liquid(s) is or are passed and within which on shafts 68 and 86 are mounted intermeshing screws 58 and 60 which in operation rotate as indicated in opposite directions, the upper portions of the screws not being immersed in liquid and the screws being so mounted that the nip between the screws can be adjusted. A gas or vapour space with an outlet 52 is provided above the screws and a heating or cooling jacket 28 surrounds the vessel. Treated liquid is discharged from an outlet at the bottom of a portion of the vessel 16 in which the vessel closely confines the whole of the peripheries of the screws and in which a liquid seal is formed between the intermeshing turns of the screws. In this portion of the vessel the pitch of the screws may be reduced and edges of the screws may have a rectangular profile. The vessel may be divided into a plurality of zones by one or more transverse partitions. Each such zone is separated from an adjacent zone by a section of the vessel which closely confines the whole of the peripheries of the screws through which liquid is transferred without allowing passage of gas or vapour. The gas or vapour space of each zone has a gas or vapour outlet. The apparatus is particularly suitable for treatment of viscous liquids. In an example polyethylene terephthalate was polymerized, ethylene glycol being removed under subatmospheric pressure. Preferably the reaction is effected in a series of zones maintained at sequentially diminishing pressures, the pressures in the zones ranging from 1 to 20 mm. Hg down to 0.1 to 2 mm. Hg.

Abstract: 435,064. Slag wool. BUSS, J., 114, Eglington Avenue East, Toronto, Canada. May 22, 1934, No. 15287. [Class 22] [See also Group II] Rock wool is manufactured from siliceous - material such as rock, metal ore, or slag by pouring the molten material in a thin stream on to the marginal surface of a thin metal disc rotating at high speed and utilizing the rotation of the disc to discharge air or other fluid such as paraffin oil from beneath the disc on to the mineral fibres. The disc is rotated at such a speed that the contact of the molten material raises its temperature to a red heat ; a ribbon of molten material adheres to the marginal surface of the disc and shot is thrown off with fibres extending between the ribbon and the shot. In the form shown in Fig. 1 molten material falls from a furnace 1 on to a thin metal disc 2 at a point near its periphery, the disc being mounted on a shaft 3 driven by a motor 5. The disc has vanes 6 on its underside which may be arranged radially or may be tangential to the hub of the disc as shown in Fig. 3, and which create an outward current of air from below the disc. A fluid such as paraffin oil may be supplied to a point below the disc by a pipe 7, the oil being carried outwards with the air and forming a coating on the fibres. In the form shown in Fig. 4 the vanes are omitted and treating fluid is supplied through a duct in the driving shaft 3<x> to a dished member 8 located below the disc and is carried outwards by the rotating disc through an annular mouth 8<x>. Walls 9 and 10 may be provided to separate particles of different specific gravities, e.g. to separate shot from fibres. Specification 373,932 is referred to.

Title: Improvements in Methods of Treating Filaments for Incandescent Lamps.
IPC: H01K3/02
Filed: 1918-09-24
Abstract: 120,040. Westinghouse Lamp Co., (Assignees of Ramage, J. H.). Oct. 15, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Filaments of tungsten, molybdenum, tantalum, or the like are heated in such a way as to acquire a granular structure adapted to restrain struc. tural alterations in use. A texture of medium fineness, containing say 12000-18000 grains per sq. millimetre, is found to be most resistant. A coarse structure is obtained by maintaining the filaments for some time at the critical temperature, namely 1800‹ C., at which grain-formation begins, and a fine structure by heating rapidly to a temperature above the critical point. Successive heating to both temperatures gives a texture of medium fineness. A 40-watt 110-volt drawnwire filament, if heated in the otherwise finished lamp first for 5 minutes by a current at 80 volts and then for a like period at 130 volts, acquires a fineness of 12000 grains per sq. millimetre. Heating for 15.minutes by a current of 110 volts gives a fineness of 18000 grains per sq. millimetre.

Abstract: 400,877. Centrifugal pumps. WILFLEY & SONS, Inc., A. R., Denver, Colorado, U.S.A. May 31, 1933, No. 15709. Convention date, June 27, 1932. [Class 110 (i).] A centrifugal pump 35 or a similar machine is driven by an electric motor having its rotor 6 on the pump shaft 7 ; axial movement of the shaft causes the surfaces 47, 48 to engage to prevent leakage when the pump is at rest and causes their disengagement when the pump is running. The end members 2 of the motor have feet or lugs 49 by which the motor can be secured to a base, and end bells 3, 4 are provided to carry the bearings. The outer ball race 9 of the bearing in the end bell 4 is free to move axially in its support, while the inner race 10 of the bearing in the end bell 3 is carried on a sleeve 14 in which the shaft slides. The sleeve 14 has lugs 22 in which are pivoted arms 23 with weights 24 on their outer ends. Grooves 27 in rings or extensions of the end bells serve as lubricant seals on each side of the bearings. A sealing ring 43 on the pump shaft has a surface 47 adjacent to the surface 48 on a ring 46 in a groove in a removable ring 44 secured to the housing. When the shaft is stationary the spring 20 moves it so that the surfaces 47, 48 are in contact to prevent leakage from the pump. When the pump is working the weights 24 fly outwards and the inner ends of the arms 23 move the shaft so that a running clearance is effected between the surfaces 47, 48.

Title: Improvements in electric starting systems for internal combustion engines
Filed: 1933-06-02
Abstract: 424,882. Starting prime movers. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. June 2, 1933, No. 16011. Convention date, June 4, 1932. [Class 38 (iv)] A starting motor SM for an internal-combustion engine is energized by closure of an electromagnetic switch 4 the coil 17 of which is controlled by the ignition switch 15 and by two sets of contacts 18, 21 ; 26, 28 in parallel, one set, 18, 21 being controlled by the motor current and the other set by current in a coil 38 energized by the residual spinning voltage of the motor when the switch 4 is open and by a part of the battery voltage through a resistance 43 when the switch is closed. A coil 35 energized from the generator G also controls the contacts 26, 28 which are normally closed and are opened by an armature 31 through a spring returned toggle connection 29, 32 a time delay being introduced by a bellows arrangement 45 to prevent opening of the contacts 26, 28 before the contacts 21, 18 are closed. A contact 42 cooperating with the contacts 6 of the switch 4 is operated by an arm 41 moved by the switch member 7 to open a short-circuit across the resistance 43 because the coil 38 is designed to make full use of the weak momentum currents of the motor and should not take the full battery voltage. During normal operation of the engine the generator voltage maintains the contacts 26, 28 open but should the engine stall before being properly started the spinning voltage of the motor maintains the contacts 26 28 open so as to ensure re-engagement of the driving pinion when the motor is re-energized. The action of the generator G is assisted by connecting it, through a safety resistance 54, and a switch 49 responsive to fluid pressure generated by the engine, across the battery so that during normal running and on the occurrence of back-fire fluctuations in pressure in a cylinder 53 connected, for example, to the intake manifold operate the switch 49. The resistance 43 may be omitted. Specifications 413,031 and 420,372 are referred to.

Filed: 1936-06-08
Abstract: 479,748. Zoetropes. LAMAC, K. June 8, 1936, No. 16041. Convention date, Jan. 18. [Class 97 (i)] In projecting and taking spirally arranged images on plate-like carriers intermittently fed by engagement of a claw feed with a spiral row of holes in the plate, the angle between the working plane of the claw and the line joining the initial position of the axis of rotation of the carrier to the optical axis of the projector or camera is changed during the traversing of the spirals correspondingly to the increased curvature of the spirals. As shown in Fig. 5, the disc e pivoted at f is fed by engagement of a claw k with holes l and is illuminated by a lamp g through a shutter and a condenser h to project an image on the screen i. The principle of the invention is shown in Figs. 3 and 4, which show feed holes A, B and a, b located on spirals I, II on the disc. The centre of the disc is at M and initially the plane of the feed claw k coincides with the line A and B. When the disc P has been fed into the position P<1> with its centre at M<1> so that the hole a registers with the claw k, the hole b instead of coinciding with the position of the hole B will be at b<1> so that engagement of the claw is not possible. Displacement of the centre M to M<2> will effect coincidence of the hole B, b<1> so that according to the invention the centre M of the disc is guided along the line M, M<2> by the slot n. Alternatively, as shown in Fig. 4, the centre M of the disc is initially displaced from the line drawn perpendicular to the plane of operation of the claw, to the position M<1> and is guided during projection along the line M<1>, M<2>. Images may be recorded directly on to the plate and copied by contact printing on to another plate or alternatively a kinematograph film may be copied by employing the apparatus. The central portions of the plate may be stamped out and the starting point of the spiral row of holes may be provided with a slot extending to the margin to facilitate. insertion of the claw k, and the last turn of the spiral may be so constructed that the apparatus works idly after the completion of projection.
