Title: Improvements in the manufacture of artificial textile materials by wet spinning processes
Inventor: PAGE CLIFFORD ERNEST
IPC: D01D5/06
Filed: 1954-06-18
Abstract: A wet-spinning device adapted for downward spinning comprises a spinning tube having an orifice at its lower end for the passage of filamentary material and coagulant from the tube, means for drawing the filamentary material away laterally immediately at the orifice, and a plate below and closely spaced from the orifice and set or capable of being set at a downward inclination in the lateral direction of travel <PICT:0787564/IV (a)/1> of the filamentary material from the orifice.  As shown, a stream of coagulant and the wet spun yarn 5 pass out of the lower end 3 of a spinning tube through a restricted orifice 4 having a smooth rounded edge, the yarn 5 being at once drawn horizontally to one side by a godet (not shown).  The stream of coagulant almost at once impinges upon a sloping plate 11, down which it flows until it reaches the lower edge 15, whence it falls into any suitable collecting means.  If any filaments break, that part of the filament which is behind the break does not remain in the coagulant stream, but is picked up and carried along by the unbroken yarn.  The upper surface of the plate 11 is 0.25-1 inch below the orifice 4 and the longer sides of the plate are parallel to the lateral direction of travel of the yarn from the orifice. Except along its lower edge 15, the plate is provided with a low wall 16.  The plate is pivotally mounted by means of downwardly extending brackets 12 on one arm of an L-shaped member 9 and is held at the required degree of slope by means of a nut 13 and a spring washer.  The L-shaped member is pivotally mounted at the end of a bracket 6 and can be fixed in any desired position by means of a locking wing-nut 10.  It may be swung out of position when starting up the spinning operation.  The bracket 6 is mounted on the spinning tube 3 by means of nuts and bolts 7.  The apparatus may be used for wet spinning acetone solutions of cellulose acetate into aqueous acetone or aqueous diethylene glycol diacetate; acetic acid solutions of cellulose acetate into aqueous acetic acid or water, either of which may contain a high concentration of a salt such as an alkali metal acetate. Solutions of cellulose propionate or butyrate, viscose or cuprammonium solutions or solutions of polymers and copolymers of acrylonitrile, vinyl chloride and other vinyl compounds may also be spun in the apparatus.  Specification 720,187 is referred to.

[Class 87 (ii)] [Also,in Group VI] A machine for applying a layer of plastic material to an article., as in the application of a layer of cream to biscuits, comprises means whereby the plastic material is taken up within the confines of a stencil plate and the wad thus formed ejected by fluid pressure The hollow cylinder 1 with stencil openings 2 spaced around the periphery is fed with plastic material 3 which is forced into the openings 2 by gravity and forms wads within the openings by removal of the surplus material by stationary exterior and interior scrapers 4, 8 acting in conjunction - with the rotary hollow cylinder 1. The scraper 8 may be adjustable and formed integral with the air nozzle 9. The exterior scraper 4 is pivoted at 15 and acted upon by a set-screw 7 to obtain maximum pressure of the stepped edge 6 of the arrow head 5 of the scraper 4 against the cylinder 1. To avoid rolling up of the wad against the back edge of the stencil opening 2 an abutment 20 is mounted on the nozzle 9 and scraper 8 to form a compression pocket 11. The wads of plastic material 3 are forced from the stencil by constant air pressure from the nozzle 9 or by intermittent waves of air pressure synchronized with the rotation of the cylinder and the passage of biscuits 13 on the conveyer 14 beneath the cylinder. The ejecting air may be of variable temperature. The stencil may take the form of an oscillating flat plate, a rotatable disc or a shallow cone.

Refrigerating, compression machines for; refrigerators, domestic and like.-A compression machine suitable for sulphur dioxide and adapted for mounting on a domestic refrigerator is provided with a condenser and evaporator in sections to facilitate repair or variation of capacity. The compressor 23 and its driving-motor 24 are mounted on a base 14 on top of the refrigerator and the evaporator 12 depends through an opening 13 in the top of the chamber, while the condenser 18 is suspended by brackets 19 from the support 14 and is cooled by the atmosphere.

Title: Improvements in electric time switches

Filed: 1936-07-03
Abstract: 460,868. Time switches. OHRENEDER, K. July 3, 1936, Nos. 18529 and 18530. Convention dates, July 22, 1935 and June 22, 1936. [Class 38 (v)] A time switch comprises a disc 7 fixed on the hour spindle 8 of a clock and having pivoted on it at 11 an arm carrying an insulating blade 45 biassed by a spring 13 to separate two pairs of spring contacts 10 mounted on the disc and connected in circuit by means of slip rings. Pivoted at five-minute intervals all round the casing are levers 20 held in the neutral position shown by springs 23 engaging hollows 21 in the levers. A knurled setting ring 2 having a glass front 3 is rotatable on the casing and carries a spring-returned plunger 17 which can thus be moved to the position on the dial 4 corresponding to the time at which switching on is required. The plunger 17 is depressed and pushes the corresponding lever 20 inwards where it is held by spring 23 engaging part 24. The free end 16 of the spring is then in the path of a projection 15 on the arm carrying the plate 45 so that at the set time the arm is tilted against spring 13 and the contacts 10 are allowed to close. The circuit is opened again when the projection 15 passes clear of the end 16 of the spring 23, and the lever 20 is returned to the neutral position by a spring arm 25. To close the circuit for a long period, all the levers 20 lying in that period must be moved to the operative position. Any levers accidentally pushed in may be withdrawn by a bell-crank lever 44 actuated by pulling out the plunger 17. In a modification, Fig. 6, the inturned levers 20 are engaged by a member 60 on an arm 59 fixed on the hour spindle 8. This causes member 60 to be momentarily clutched on to a loose ratchet disc 57 which is thus caused to rotate a short distance. This causes a pin 58 to trip an escapement (not shown) which allows a cam to rotate 180‹ and operate a switch, a subsequent operation causing a further rotation of 180‹ to operate the switch in the reverse sense. Thus in this modification, circuit is made for a predetermined period by moving into the operative position by the same means as in Fig. 4, the levers 20 corresponding to the beginning and end of the period.

In a method and apparatus for quenching moving elongate pieces of metal there is provided a pair of spaced parallel walls arranged perpendicular to the direction of travel of the workpiece, the walls having aligned openings through which the metal - passes. A liquid coolant is projected against the outer face of one of the walls to form a substantially planar mass across the opening therein, while a gas or air is projected against the outer face of the other wall in such a way that the gas passes into the region between the plates and prevents the entry of coolant thereto. After passing through the parallel plates the workpiece preferably passes into a further quenching zone provided with means to prevent distortion. As shown in Figs.1, 4, workpiece 8 leaves furnace 10 through rolls 14a, 14b, 16a, and passes first through openings 40, 42 in plates 20, 30 into housing 50.
