Title: Improvements in and relating to the production of artificial filaments, threads, fibres and like filamentary materials from viscose
Inventor: TALLIS ERNEST EDWARD
IPC: D01F2/08
Filed: 1955-06-29
Abstract: Regenerated cellulose filaments are produced by extruding viscose at a salt point between 6 and 15 into an aqueous acid coagulating bath containing at least 0.03 per cent by weight of a polyethylene oxide having a molecular weight between 600 and 6,000, sulphuric acid in a percentage of 1.0-1.3 times that of the caustic soda in the viscose and 3-15 per cent of zinc sulphate.  Green viscoses may be spun and the freshly spun filaments are preferably subjected to stretching while passing through a hot dilute acid bath as described in Specification 467,500, [Group IV].  Specifications 557,218, [Group IV], and 634,868 also are referred to.

Title: A tool for manipulating a bolt and a nut screwed thereon
Inventor: OWEN HENRY ARTHUR
IPC: F16B31/02
Filed: 1955-06-29
Abstract: 834,786. Screwing-up and unscrewing nuts and bolts; chucks. NORTH BAR TOOL CO. Ltd., and NEWALL & CO. Ltd., A. P. June 11, 1956 [June 29, 1955], No. 18816/55. Class 83 (3). A nut-tightening tool for use with a bolt 1, Fig. 2, forming the subject of Specification 834,787 and having a screwed shank 4 with a shearable extension 3, applies thrust differentially on the extension and on a nut screwed on the shank, and comprises a housing 51, Fig. 5, containing a nut-engaging socket 65, forming part of a crown-wheel 56, and a bolt-engaging sleeve 64 forming part of a crown-wheel 53, planet-gears 59 between the crown-wheels being mounted in a worm-wheel 60 meshing with a worm 61 on a shaft 62 which is driven. In a modification, the tool comprises a body 70, Fig. 6, housing a rotary fluid-pressure motor 72 driving, via shaft 81, the sun-wheel 91 of an epicyclic gear A, the planet-wheels 94 of which are mounted on the sun-wheel of a further gear B. Similarly, with gears C, D. The planetwheels of each gear mesh with teeth on an outer cylinder 80 which is rotatable relatively to the body and end plate 73. The nose 100 of the tool has a socket 111 for the nut and teeth 102 meshing with the cylinder teeth and fixed by screw 103. The planet-wheels of the last gear D are carried by a member 99 which supports the bolt-engaging sleeve 104 provided with wedge-shaped jaws 105. Relative turning of the sleeve and member causes lateral movement of the jaws, and such turning is ensured by a friction disc 112. The fluid supply to the motor is controlled by a valve 128 and when the motor is running, fluid is also supplied beneath a piston 127, which moves a rod 126 to the right and allows plunger 122 to press cupshaped member 115, having teeth engaging the teeth of the sun-wheel of gear D, to the right. This supply is cut off when the valve is released to stop the motor, whereupon spring 124 moves rod 126 to the left and engages sleeve 104 with member 115 via dog-teeth 118 with oblique faces, thus kicking open the jaws and releasing the sheared-bolt extension from the sleeve.

Title: Improvements in or relating to liquid vending machines
IPC: B67D3/00
Filed: 1934-06-26
Abstract: 440,213. Delivering measured quantities of liquids. HENDERSON, W., 7, Hextol Terrace, Hexham, Northumberland. June 26, 1934, No. 18847. [Class 106 (v)] In a machine for vending liquids and more particularly milk, of the kind comprising a container for the liquid, a dipping measuring cup 12 operated from outside the container and tiltably mounted on a rocking arm 10 so that when the arm is raised the cup automatically tilts to deliver its contents into a hopper 14, the tilting or pivoting centre of the cup is so arranged that when the cup is free it tends to tilt and is constrained in at least one direction so that during its movement to and from the hopper it is maintained in an upright position. The container has relatively thick insulating sides and at the top supports a subsidiary liquid container 2 and a container 4 for a freezing medium. On the underside of the container 4 is supported a shaft 5 rotatable indirectly by a handle 8 and having rigidly secured to its inner end, the rocking arm 10 from which is loosely suspended a stirrup 11. The measuring cup 12 with a spout 12<a> is pivotally mounted within the stirrup so that it tends to tilt to discharging position. A stainless steel guide or runner 13 prevents tilting until the cup has been raised above the level of the hopper 14, which communicates with a delivery cock 23 through an upwardly inclined pipe 22 in which some liquid is retained forming a trap to prevent the ingress of air into that part of the container. A cover 15 over the hopper is raised before the tilting of the cup 12 either by a projection on the arm 10 or independently by a lever 16 operating through a shaft 17 and links 18. The delivery cock 23 is located outside the container and is preferably housed in a detachable cupboard.

Title: Method and apparatus for filtering or sifting out fine particles by utilizing supersonic vibration
IPC: B07B1/40
Filed: 1969-04-14
Abstract: 1,270,971. Wet screening. NIPPON STEEL CORP. 14 April, 1969 [15 April, 1968; 26 April, 1968; 5 Aug., 1968; 27 Sept., 1968; 3 Oct., 1968; 27 Nov., 1968; 30 Dec., 1968], No. 18997/69. Headings B1D and B2H. [Also in Division C7] Particles in suspension in a liquid are filtered out or graded according to size by introducing the suspension into a container in which one or more sieves are arranged and imparting supersonic vibrations to the suspension and to the sieve or sieves. In Figure 1, a suspension 10 of fine particles is contained in a container 2 in which are mounted a series of superposed sieves 3, 4, 5 with apertures decreasing in size progressively downwards. A supersonic oscillator 1 is adjustably positioned in the container and is connected by a line 6 to a supersonic wave generator (not shown). A vibration transmitter 7 is set at the tip of the oscillator 1. A funnel 8 below the screen 5 is connected to a suction pump (not shown) via a pipe 9. In operation, liquid is introduced into the container 2 and the vibration transmitter 7 is moved close to the sieve 3 and the oscillator 1 is energized. A liquid suspension of particles to be graded is then introduced into the container and if. necessary, suction is applied to the pipe 9. The vibrations serve to break up any agglomerated particles thereby preventing choking of the sieves. The sieves 3, 4, 5 are successively removed with the particles retained thereon, the vibration transmitter being successively moved down close to the sieves 4 and 5 after removal of the sieves 3 and 4 respectively. In Figure 2, an apparatus for determining the size distribution of particles of a powder includes a sieve unit 12 comprising a number of sieves placed one above the other and spaced apart from one another and clamped between a container 13 and a funnel 8 which is mounted on a collecting flask 16 provided with a suction pipe 9. Each sieve element may be constructed by immersing a metal or organic film provided with a number of holes in a treatment bath and subjecting it to chemical plating and/or electroplating whilst supersonic vibration is applied so as to contract the size of the holes uniformly by the metal layer deposited thereon and to increase the strength of the sieve element. The sieve element may be attached at its peripheral portion to a synthetic resin or rubber ring to constitute a sieve. Alternatively, the sieve is formed by fitting a sieve element F, Figure 6, in a groove 27 in the inside surface of a synthetic resin holder P which is provided with a socket 25 and a spigot 26. When a number of such sieves are mounted in the apparatus to form the sieve unit A the spigot 26 of one holder is received in the socket of a lower holder.
