Title: Improvements in knitted articles for wear and methods of making the same
IPC: D04B1/26
Filed: 1952-12-05
Abstract: 740,553. Knitting. DOUGHTY, J. C. Dec. 4, 1953 [Dec. 5, 1952], No. 30919/52. Drawings to Specification. Class 74 (2). Each plain loop of a pouch of a sea-boot stocking is linked with one plain and an adjacent rib loop of the instep portion. In knitting a 1 Î 1 ribbed instep of the stocking on a superposed cylinder machine two thirds of the needles knit the instep portion whilst the remaining third knit a plain heel, foot and toe pouch. The stocking may be shaped in the leg by gradually increasing the number of wales in which rib loops are knitted. A mitten having a palm portion knitted plain and a back portion knitted of rib fabric may have a pouch or end flap joining the two portions knitted of plain fabric and linked to the rib portion in a similar manner.

Abstract: 1,235,107. Dyeing polyamides. IMPERIAL CHEMICAL INDUSTRIES Ltd. 1 July, 1968 [5 July, 1967], No. 30991/67. Heading D1B. In the dyeing of materials consisting wholly or partly of synthetic polyamide shaped articles in the presence of jute the transfer of jute colouring matter to the polyamide is minimised by the presence of a cationic compound which is a quaternary ammonium compound, e.g. cetyl trimethyl ammonium stearate, an amine ethylene oxide condensate, e.g. a stearylamine ethylene oxide condensate in the molar proportions 1:5, or a quaternary salt of a polyalkoxylated amine, e.g. a quaternary salt of a polyethoxylated or polypropoxylated amine. Polyamide fibres of polyepsilon caprolactam, polyhexamethylene adipamide, polyhexamethylene terephthalamide or a homo- or copolymer of octamethylene diamine or decamethylene diamine and suberic or sebacic acid may be dyed. 2% by weight of both of the cationic compound may be used in an aqueous buffer system comprising for example sodium dihydrogen phosphate and disodium hydrogen phosphate or partially caustic soda neutralised mixed orthophosphoric, acetic and boric acids. Carpets having a jute backing and polyamide fibre piles may be dyed.

Title: Improvements relating to pressure-reducing valves
IPC: G05D16/06
Filed: 1932-11-03
Abstract: 407,447. Prassure-regulating valves. BELLISS & MORCOM, Ltd., Ledsam Street Works, and WARD, C. F., 146, Wentworth Road, Harborne, both in Birmingham. Nov. 3, 1932, No. 31022. [Class 135.] In a pressure-reducing valve in which an inlet valve admitting fluid under pressure to a chamber is permitted to close by the displacement of a diaphragm or piston under the pressure of the fluid after it has passed the valve, a second valve is interposed between the inlet valve and the chamber, this second valve being permitted to close only on further displacement of the diaphragm or piston. Thus leakage past the inlet valve will cause further displacement of the piston or diaphragm which will arrest further leakage by permitting the second valve to close. In Fig. 1, a diaphragm b forming one wall of the outlet chamber a is pressed inwardly against the influence of outlet pressure by a spring c causing a bell crank lever h to press on a plunger stem i which acts successively through the ball valve g and a plunger stem to push the ball inlet valve e off its seat. The valve e is pressed in the direction of flow by a spring f. The plunger stem is slightly shorter than the distance between the two ball valves when seated, so that, when the inlet valve e is closed, further movement of the diaphragm is necessary to close the second valve g. The ball valves may be replaced by conical valves. The seatings are renewable and preferably made of hardened steel. Web-guided plunger valves with stems and renewable fibre facings may also be used. The reducing valve is particularly suitable for the regulation of high pressure gas for traction purposes. According to the Provisional Specification, the second valve or both valves may have resilient seatings of vulcanized fibre. Further, the tandem valves according to the invention may be used where two piston or diaphragm chambers are arranged in series either at the inlet of the high pressure chamber or between the chambers.

Abstract: 948,120. Endless conveyers; unstacking machines. LAMB-GRAYS HARBOR CO. Inc. Aug. 15, 1962, No. 31272/62. Headings B8A and B8C. In a machine for dividing a stack S of paper into stacks Sa, Sb of equal heights, the undivided stack is moved on to an endless belt 20 where it is engaged by a separating plate 64. The lower stack Sb passes on to a conveyer belt 23 which is driven at twice the speed of the belt 20. The upper stack Sa is moved up the plate 64 by an auxiliary belt 67 and passes on to a conveyer belt 57 arranged to discharge on to a pivoted plate 99 which swings downwardly when the stack Sa moves on to it. This stack is deposited on the belt 23 but is spaced from the stack Sb. Framework.-A structure 50 carries the separating plate 64 the pivoted plate 99 and rollers 55-59 for the conveyer belt 57. It is supported at each side by parallel links 131, 132, which are pivoted respectively at 133 to side rails of an upper frame 78 and at 134 to the side rail of a frame 15. The frame 78 supports all rollers 68-71, 73, 74 which engage the belt 67 and is vertically adjustable in the main frame of the machine to accommodate the machine to stacks of different height. The parallel-linkage support of the structure 50 automatically adjusts the level of the latter so that the separating plate 64 continues to equally divide the incoming stacks. Downward movement of the frame 78 is adjustably limited by a vertical screw 150. To permit stacks to be fed through the machine without division, the frames 50, 78 may be quickly elevated by a solenoid controlled piston-cylinder means 164, 165 which actuates a cable 160 attached to the frame 78. Conveyer drive.-Fig. 10 shows how a motor 26 drives all the conveyers by chains and sprockets.

Abstract: 1532907 Numerical control system: Interpolation BENDIX CORP 28 July 1976 [12 Aug 1975] 31480/76 Heading G3N A numerical control system selectively uses linear or circular interpolation e.g. for a machine tool cutter 33 such as a lathe or drill, a graph plotter pen or the electron beam of a cathode ray tube. The control data is read from magnetic or punched paper tape 12 in unit 11 and gives the co-ordinate positions of the desired path and the type of interpolation to be used. The data is interpreted in preprocessor 16 and stored in memory 18 connected to linear and circular interpolators 22, 23. The linear path is divided into a series of equal straight line segments as an inverse function of the feedrate. At any one time unit 27 selects the output of one of interpolators 22, 23 and controls the machine tool 33 via servo control 31 using analog servos or digital pulse motors. The system is operator controlled from unit 19 where control data such as feedrate changes can be entered and data can be displayed. The control can be effected by special purpose circuitry or a programmed digital computer.

In the mechanism shown in the Figure, a rod 5, arranged parallel to a carriage rack 1, is mounted in bearings 3, 4. The rod is formed at one end with a bend 6 having a pawl-tooth 7, and is formed at the other end with a bend 8 engaging a cam slot 9 in a bell-crank 11 which is connected by a link 15 to a bell-crank 19 provided with a key 21. On depressing the key the rod rocks the tooth into engagement with the rack and then moves longitudinally to effect back-spacing. The bearing 3 engages the bend 6 to limit the movement, the tooth remaining in engagement and preventing overthrow. On release of the key, a spring returns the members to normal position, the rod rocking initially to release the tooth, and then moving longitudinally until the bell-crank 11 engages a stop 25. The rod is retained by a bladespring 22 through which the rod passes. The spring flexes to reduce resistance to the od during- the return movement.
