Title: Improvements in or relating to the weaving of closely woven fabrics
IPC: D03D49/60
Filed: 1941-11-21
Abstract: 553,543. Loom shedding-mechanism. SULZER FRERES SOC. ANON. Nov. 21, 1941, No. 14977. Convention date, Dec. 31, 1940. [Classes 142 (i) and 142 (ii)] In weaving closely woven fabrics, the groups la, 1b of warp threads moving alternately to form the shed cross at a point 8 between the mid position and one extreme position of the shaft lift. During beating up, which follows the time of the crossing of the warp threads, the tension of one group 1b is greater than that of the other group 1a which at this time are towards the middle of the shed. The warp threads passing from the back rail 2 to the fabric 4 are preferably in a single plane when the corresponding shafts are in their mid position. The shedding motion is obtained 'from cams 20, 21 operating upon rollers 18 mounted upon levers 16 pivotally mounted upon a stud carried by levers 22. The levers carry rollers engaging cams 29, 29a so that additional movement is imparted to the levers 16 and shaft rods 30. The amount of additional movement can be varied by adjusting the levers 22 about their points 24 of mounting.

Title: Improvements in or relating to transfer sheets
IPC: B41M5/10
Filed: 1963-04-17
Abstract: Compositions used in making transfer sheets (see Division D2) comprise:  (1) polystyrene emulsion, carbon black, butyl benzyl phthalate, butadiene-styrene copolymer emulsion and water; (2) polystyrene emulsion, alkylketene dimer, carbon black, butadiene-styrene copolymer emulsion and water; (3) and (4) polystyrene emulsion, butadiene-styrene copolymer, phthalocyanine blue and water; (5), (6) and (7) similar to (3) but with polyvinyl chloride latex, polyacrylic emulsion and polyvinyl chloride emulsion respectively in place of the polystyrene.ALSO:A transfer sheet comprises a flexible foundation, e.g. of paper, and a coating of discrete spheres of organic polymer, e.g. polystyrene, and a non-waxy adhesive.  The adhesive is present in an amount sufficient to hold the polymer spheres to one another and to the foundation, but not to hold them to the foundation when subjected to local pressure.  The coating is equivalent to 1/2 to 3 1/2 ounces per 100 sq. ft. of foundation, and may also contain colouring matter, e.g. copper phthalocyanine or carbon black.  The organic polymer of the spheres may be polystyrene, a polyacrylic resin or polyvinyl chloride.  The adhesive may be polyvinyl alcohol, starch, starch ether, chlorinated or oxidized starch, carboxymethyl-cellulose, partial pentaerythritol ester of wood rosin, gelatin, polyacrylamide, vinyl acetate polymer or copolymer, polymer of an acrylic acid derivative, a butadiene-styrene copolymer, acrylic-vinylidene chloride copolymer or casein.  The transfer coating may also include a plasticizer, calcium, potassium or ammonium stearate, a polyoxyethylene glycol, lecithin, polybutene, polyethylene, soft wax or alkylketene dimer. The transfer sheet may have a release coating of vinyl chloride-vinylidene chloride copolymer, polyamide, acrylic or methacrylic polymers, hydroxyethyl-cellulose, sodium silicate or colloidal silica, between the base and the transfer coating.  The transfer sheet may be used with a copy-receiving sheet of paper having a coating of calcium carbonate and adhesive.  When pressure is applied locally, the transfer layer is completely transferred, in the areas to which pressure is applied, to the copy-receiving sheet, so that the transfer sheet itself also forms a legible copy.  The trace may be made permanent by heating the transfer sheet or copy-receiving sheet or both to a temperature at which the polymer is fluid, so that its discrete particles coalesce and are no longer pressure-sensitive.

Title: A machine for transferring articles along a straight line from one working station to the next following working station
IPC: B65B35/16
Filed: 1947-06-10
Abstract: 639,003. Packing. SKODA WORKS, PLZEN. June 10, 1947, No. 15232. Convention date, June 12, 1946. [Class 94(i)] [Also in Group XXX] In a machine such as a packing machine in which an article is forwardly transferred along a straight line between adjacent working stations by means of gripping devices, two of the devices operate along the same working line with a time lag of half the working cycle, the returning idle device being caused to carry out additional motion in order to avoid the other device, all the movements of the devices being derived from two camways provided in a single cam-disc. In the construction shown, rollers 3, 10 carried by respective arms 4, 11 are engaged by an internal cam surface 2, whereby reciprocating movement is transmitted by respective rods 6, 13 to sliding gripping devices 7, 14. Each pair of gripping devices comprises a fixed jaw 8 carried by a sleeve slidable on a rod 17, and a jaw 9 which is spring-urged into gripping engagement with an article to be conveyed. The article is transferred from station A to station B and then to station C by the tongue 7, and back from C to A by the tongs 14. In order that the tongs 7, 14 shall not come into mutual engagement during their travel, rotation is imparted to the rods 17 by pinions 31, 30 and racks carried by respective links 26, 27 (26 only shown) connected with rollers 20, 21 which are in engagement with a second internal cam surface 19.

Title: Apparatus for hoisting hydroplanes or bodies floating on heavy seas
IPC: B66D1/48
Filed: 1938-05-23
Abstract: 496,189. Winches. SOC. DE CONSTRUCTION ET DE LOCATION D'APPAREILS DE LEVAGE. May 23, 1938, Nos. 15290 and 15291. Convention dates, Dec. 17, 1937 and March 21, 1938. [Class 78 (v)] In winches of the type in which a pilot hook is attached to a floating body, rising and falling with the waves, to facilitate its connection to a main lifting hook, and having friction means for maintaining the main cable taut, the lowering or lifting of a powertransmission pawl into and from effective position is caused by a friction-drive operated from the shaft of the friction device which produces the tension in the main cable. A motor 20 drives through pinions 23, 24, 26, the cage 27 of a sun-and-planet gear 35, 35<1>, the sun wheel 34 of which is fixed on the drum shaft 32. An alternative drive from the lay shaft 25 through friction discs 29, 29<1> and pinions 28, 31 maintains the tension of the main cable 11. On the drum shaft 32 is a ratchet wheel 33 engageable by a pawl 38 pivoted at 39 and loaded at 40 so as normally to hold the wheel 33 stationary in the direction a. A balance lever weighted at 41 tends to press the load 40 upward and to disconnect the pawl 38, but a hand lever 43, pivoted at 39 and provided with a spring-pressed detent 44 taking over a projection 45, carries a pin 42 which holds the balance lever out of action when the lever 43 is depressed. The load 40 is also controlled by a crank finger 46 on a spindle 47 having a weighted radial arm 48 adapted to be lifted by a finger 49 adjustably gripped on to the shaft 32. In operation, the light tackle 16 is hooked on to the load 17 by an operator thereon and drawn taut, and the motor 20 is started at a speed to raise the hook 15 slightly faster than the rise of the load 17 on the wave. The lever 43 being held up, the pawl 38 is free, and the hook 15 can be dragged down, to engage the load 17, by reason of the slip of the clutch 28, 29, 291. On lowering the 'lever 43 the pawl 38 can engage the wheel 33 when the load 17 tends to descend down a trough, and the shaft 32 starts to turn in the direction a and the finger 49 turns the spindle 47 to drop the crank finger 46. The shaft 32 is then held stationary and the sun-andplanet gear functions to rotate the drum 37 and lift the load clear of the waves.. The pawl 38 may alternatively be electrically operated from a distance. A servomotor may assist the operation of tackle 16. In another form the cable of tackle 16 extends through a pulley block to a smaller drum on the shaft 32.
