Patent GB-716827-A (GB)
Title: Improvements relating to a method for obtaining fibers or films by the wet-spinning and wet-forming processes
IPC: D01F6/18
Filed: 1952-05-21
Abstract: A solution of an artificial or synthetic film or fibre forming material is extruded into a bath comprising a mixture of a precipitant and a liquid which is the solvent phase of the spinning solution, the fibres or film being withdrawn upwardly from the bath through a washing liquid flowing in a confined stream <PICT:0716827/IV (a)/1> in an opposite direction to the travel of the fibres or film and which comprises the precipitating liquid and optionally a minor proportion of the extrusion solvent, the washing liquid being collected and liquid collected from the washing step being continuously delivered to the precipitating bath at a predetermined rate dependent upon the proportions of precipitant and solvent in the washing liquid and upon the amount of solvent being introduced into the precipitating bath from the extrusion solution so that the proportions of precipitant and solvent in the precipitating bath remain constant.  The fibre or film forming material may be cellulose acetate, copolymers of vinyl chloride with vinyl acetate or acrylonitrile, polyamides, polyesters, copolymers of acrylonitrile with vinyl acetate, styrene, 2-vinyl pyridine, 5-vinyl-2 methylpyridine, isobutene, dimethylfumarate, methylmethacrylate, methacrylonitrile or acrylic acid and its esters.  The solvent, selected according to the film or fibre forming material, may be acetone, hot phenol, formamide, chloroform, dimethylformamide, dimethylacetamide, or dimethyl propionamide.  The precipitant which is an extractive for the solvent and is inert to the fibre or film forming material, may be water.  At the start of a spinning operation the proportions of precipitant and solvent required in the liquid being delivered from the washing step and the rate at which it is delivered to maintain constant proportions in the precipitating bath are determined by observation of the refractive index of the bath. The washing liquid may be heated up to 100 DEG C. and when the spinning is conducted at temperatures below this the collected washing liquid is cooled.  The fibres may be stretched while passing through the washing liquid or subsequently.  An apparatus for carrying out the method comprises a precipitating bath 2 in which the solution is extruded from a nozzle 1 and which is maintained at a constant level by an overflow 16.  Washing liquid is delivered from a pipe 10 into a vessel 9 the level being adjusted by an overflow 12, and a stream of washing liquid flows through a channel 6 into a collecting vessel 13 provided with cooling apparatus 18 and an overflow 17.  Liquid from the vessel 13 is delivered through a pipe 14 and valve 15 to the precipitating bath.  The fibre is guided through the bath 2 by a thread guide 3 and through the channel 6 by godets 4 and 7 over which and over spacing guides 5 and 8 it may be lapped several times.

Title: Improvements in and relating to television systems
IPC: H04N3/12
Filed: 1934-04-28
Abstract: 430,940. Television. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Communication Patents, Inc. ; 60, Broadway, New York, U.S.A.) April 28, 1934, No. 12915. [Class 40 (iii)] In a scanning arrangement for transmission or reception comprising a plurality of elements mounted in a definite pattern means for supporting said elements and means for changing the position of said elements in a serial order under control of electrical impulses the elements are prepared for change in serial order by means independent of the said electrical impulses which loosens the said elements on their supports in serial order. Light from a constant source 13 is projected on a screen 10 of elemental shutters 33 carried on horizontal wires 25 secured at one end to a wave absorbing member 21 and at their other ends connected to a vertical member 28 along which a wave is propagated by an impulse producing member 34 controlled by an oscillator 11. The dimensions of the members 25, 28 are chosen so that a wave passes along a wire 25 whilst the exciting wave traverses the distance between two of the wires 25, and the shutters 33 are loosened on their supports in serial order. The picture impulses are applied to a coil 8 which effects the setting of the shutters as they are loosened and they are retained in their adjusted positions by the co-operation of a polygonal sleeve with the polygonal section of the wires 25. Alternatively the shutters may be maintained in their adjusted positions on the wires by light coil springs. In a modified arrangement Figs. 7, 8 waves of two differing high frequencies may be applied by an oscillator 48 and harmonic generator 49 to members 43, 44 associated with wires, &c., 41 in adjacent parallel planes. Each elemental area is represented by two shutter members mounted on the wires 40, 41 and joined by a spring so that the assembly is resonant to the beat frequency. The use of wave absorbing members 20, 21 of Fig. 2 may be obviated by extending the wires 25, 28 beyond their operative points to a support so that the reflected wave in the extended portion is neutralized by the succeeding wave. A lattice 18 placed behind the screen 10 obstructs light passing through the openings between the shutters and a lens mosaic 17 is arranged to eliminate the shadow of the shutter supports. The arrangement may be used at the transmitter by replacing the receiving arrangement 7 by an oscillator which through coil 8 opens and closes each shutter during the time it is loose on its support. Specification 360,470 is referred to.

Title: Method of and apparatus for manufacturing satchel bottom bags
IPC: B31B37/00
Filed: 1934-04-30
Abstract: 437,449. Making paper &c. bags. SMITHE MACHINE CO., Inc., F. L., 633, West 44th Street, New York, U.S.A.-(Assignees of Novick, A. ; Flushing, New York, U.S.A.) April 30, 1934, No. 12978. Convention date, May 5, 1933. [Class 94 (ii)] A method of forming satchel bottom bags consists in folding a continuous web of paper &c. about a flat former having its forward end bifurcated to form spaced parallel former plates, simultaneously tucking in the corners of the forward end of the tube into the space between the former plates, advancing the tube, and cutting off the forward part of the tube having the tucked-in corners so as to form a bag blank and then completing the manufacture of said blank into a finished bag. A web 20 from a roll 21 is fed by rolls 36, 37, 38, past a folding device 25, 26, 31, 32, an edge being gummed at 24, to a reciprocable former plate 30 with a bifurcated forward end 61, 62, around which it is formed into a lapped tube, the rolls 36, 37, 38 acting on the tube of material through cut-outs in the former plate. This latter is mounted on a spring- biassed carriage 46 on a track 47 and is reciprocated by cam-and-lever mechanism 54, 52, 50. Tucker blades 75, mounted on a spring- biassed carriage 78, and reciprocating on the track 47 by an oscillating shaft 84, effect the tucking in of the bag tube corners between the former plate portions 61, 62 when a crossbar 82 actuates them by contacting with rollers 81 mounted thereon. Further feed rollers 90, 91 operating at the same speed as the rolls 36, 37, 38, grip the folded-in tip of the bag tube blank directly it is cut from the tube by a blade 97 carried by a roller 96 and actuated by a cam 101 through a spring biassed lever 99, forward the blank to ironing rolls 112, 111, suction rolls 113, 114 for opening the two superposed triangular flaps and rolls 120, 121 which apply gum patches 124/125, by means of pads 122, 123, on the opened flaps and crease them at 131, 143 by means of blades 130, 142. A gripper device 132 grips and folds over the tip of flap 106 and the partly folded bag is then fed by a roller 140 gapped at 141 to clear the gum patch 125, to a pair of belts 150, 151 where the bottom portion is completed by a blade 160 on an oscillating arm 161, which folds over the tip of flap 105 on to already folded portions.

Title: Improvements in machines for uniting knitted webs
IPC: D04B15/00
Filed: 1928-05-03
Abstract: 316,357. Haddan, R., (Scott & Williams, Inc.). May 3, 1928. Knitted fabric sewing- machines.-A machine for uniting knitted webs such as the toe pockets of seamless hosiery produced on circular knitters, has means for the convenient application and removal of the transfer ring carrying the loops to and from the carrier and for moving the ring and carrier for proper co-ordination with the sewing machine which unites the loops. Assuming the machine to be at rest and the sleeve 65 of the carrier 20 elevated as shown in Fig. V, the transfer ring R, carrying the loops of the knitted fabric on its points P, is placed in the sleeve 65 and locked therein with the end of the fabric trailing down within the carrier. The finger lever 110 is then moved to shift the trigger 113, causing the blank space 109 of the control drum 40 to be advanced and resulting in ihe commencement of the intermittent rotation of the drum by the pawl 107. During the first movement of the drum, the pin 87 trips the lever 85, Fig. VI, causing the lever 81 to be rocked from the full-line position to the dotted line position of Fig. V so that its roller 79 is withdrawn from beneath the sleeve 65 which drops, carrying the ring R. Consequently, the lower part of the ring is seated against lateral displacement and its points P are correctly positioned for sewing by the sewing machine S. Dur. ing the ensuing progression of the control drum 40, the finger 44 is first moved inwards to engage the pivoted section 32 of the transfer ring R by the cam lug 40<x> on the drum, whereupon the sector 49 is actuated, as determined by the cam groove 40<a> of the drum 40, to swing the transfer ring section 32 over upon the main ring section 30 to double the loops in the points P. The lever 53 is then actuated by the cam grooves 40<b>, 40<c> and levers 55, 57, 56, 58 to reciprocate the stripper within the carrier. The ring section 32 is then restored to its original position by return movement of the gear sector 49, and the finger 44 retracted through the passing of the cam lug 40<x> beyond the pivoted region of the arm 43. The doubled fabric loops being now doubled on the points of the ring section 30, the carrier 20 is set in motion by withdrawal of the latch 59 and by the jogging of the finger 63. The carrier is rotated one tooth at a time to present the points P successively to the sewing machine S to unite the doubled loops. When the stitching is complete, the chain of stitches is cut by shears and the mechanism returned to its starting position.

Abstract: 528,303. Fastening sliding roofs of vehicles. BAIER, W., and BAIER, 0., (trading as BAIER METALLWARENFABRIK, W.). May 3, 1939, Nos. 13261, 13262 and 13263. Convention dates, May 4, 1938, May 11, 1938, and March 17, 1939. [Class 108 (i)] [Also in Group XXV] In a sliding roof for a vehicle in which the locking of the roof in the closed position is effected in conjunction with the operation of brake members carried by the roof and co-operating with lateral guide rails 41, the handle 6 actuating the catch member 1 and the lateral brakes 26, 44 requires a half turn to complete the actuation of the catch, the last 45 degrees of which actuate the brakes. As shown in Fig. 1 a cross-beam 9 of the sliding roof is locked to a cross-beam 18 of the fixed roof by the catch 1 pivoted at 16 to a disc 11 fixed to a shaft 4 to which the handle 6 is attached. Several teeth '12 project from the disc 11 and these engage with a toothed sector 10 attached to a cam 7 mounted on a pivot 5. The cam is recessed at four points to receive rollers 8 on bars 2 actuating the brakes 26, the rollers being pressed into engagement by springs 28 mounted on rods 24, 25 slidable in brackets 23 on the bar, the reaction of the springs being taken by brake 26. When the handle 6 is to be turned into the release position, Fig. 3, the first 45 degrees of the rotation rotates cam 7 through 90 degrees by teeth 12 so that recesses 30 come opposite rollers 8 and as the distance apart of these recesses is less than the others the brakes are withdrawn from engagement. The remaining 135 degrees of the rotation disengages the hook 1. In Figs. 6, 7 the sector operating the brake rods 2 is pivoted at 52 towards one side of the disc 11 operating the hook 1, the rods 2 being connected to the sector by links 47, 48.

Filed: 1918-08-16
Abstract: 131,154. Davis, H. S., and Davis, M. D. Aug. 16, 1918. Gas analysis.-The amount of a vaporous constituent of a gas is measured by measuring the partial pressure due to the vapour in an apparatus comprising two similar flasks 1, 2, connected through a manometer 3, and having rods 6 passing through the stoppers, sealed by rubber tubes 8. Small sealed bulbs 10 containing the liquid or solid, corresponding with the vapour to be measured, are attached to the bottom of the rods, and are adapted to be broken against the bottom of the flasks by pressure on the rods. One of the flasks is filled with the gas to be analysed and the other with air, the pressures are brought to atmospheric by momentarily opening cocks 11, and the bulbs 10 are broken. The pressure in one flask is increased by the full vapour pressure, while that in the other is increased by this amount less the pressure due to the vapour already in the gas. The pressure difference shown on the manometer measures therefore the vapour pressure which existed in the gas, Solutions may be used in the bulbs 10. The sum of the vapour pressures due to more than one constituent of a gas may be measured by using a solution which evolves one of the vapours and dissolves the other vapours. The " light oil" vapours in coal gas may be measured by using benzene, or benzene and toluene, or benzene, toluene. and xylene in the bulbs 10. The flasks may be packed in melting ice and solid benzene used in the bulbs.
