Title: Improvements in or relating to presses
IPC: B21D37/14
Filed: 1961-04-19
Abstract: 906,577. Machine-tool details. REPUBLIC DIE & TOOL CO. April 19, 1961 [April 25, 1960], No. 14066/61. Class 83 (3). [Also in Group XXIX] A press, which may be used for indicating high spots in dies, comprises actuating means 50, 52 mounted on a head 16 for moving a platen 18 between a base 12 and the head, the platen carrying guide members 62 extending upwardly through bearings 70 mounted in the head, and a cover 20 which, with the head, substantially encloses the guide members, bearings and actuating means when the platen is in its upper position adjacent the head. The bearings consist of spaced members 70 mounted in tubes 72 secured to the head and receive the guide members which are in the form of tubes 62 secured by flanged mounts 66, 68 to plates 64 welded or otherwise secured to the platen 18; lubricant 73a is disposed between the members 70 and wipers 73 are provided to prevent entry of dirt into the bearings. The platen is secured to the actuating means which consists of a ram 50 slidable in a cylinder 52 mounted on the head or a screw mechanically driven from a motor. The platen, head and base are of grid structure, the base and head being joined by H-sectioned columns 14 and tie rods 46. The workpiece 76, such as a die, is mounted on the base 12 and the upper die or a master die 74, which may be of plaster is secured to the platen, the upper die being coated with a blue stain or pigment so that when lowered it indicates the high spots on the lower die. The upper die is then raised and the high spots removed by grinding, the grinding dust being prevented from reaching the guide members, bearings and actuating means by their being substantially enclosed by the head and cover when the platen is in its upper position.

IPC: F01L21/04
Filed: 1918-09-02
Abstract: 131,471. Twells, A. H. Sept. 2, 1918. Link-motions and linkage gears; expansion valves.-Consists in the addition of an expansion valve to the duplex pump described in Specification 22332/14, wherein each valve is moved to the open position by the other engine, and is moved to the mid or closed position by its own engine. In the arrangement shown in Fig. 11, the expansion valve comprises two parts held down by springs k, which may be relatively adjusted by rotating the spindle l. In the construction shown in Fig. 13, the expansion valve is actuated by a projection p<2> on the main valve-rod which engages adjustable tappets p<1>. In the construction shown in Fig. 15, the motion of the valve is taken from one of the rods v, t by lever mechanism w, x. A method of adjusting the stroke of the valve by altering the pivotal connexion of the link x is shown in Fig. 18. The main and expansion valves may be formed as concentric piston valves. Means comprising a diaphragm or piston and spring may be provided for automatically regulating and varying the cut-off by adjusting the position of the fulcrum of the lever w to meet varying conditions of steam or water pressure. Or the cut-off may be effected by speed-responsive means or by a variation in the length of stroke. A ram acted on by the cross-head may force liquid into a cylinder with a by-pass containing a spring-pressed piston connected up to the cut-off mechanism. The invention may be adapted to Corliss valves.

Title: Improvements in the production of colour resists on textile materials
IPC: D06P5/12
Filed: 1934-05-11
Abstract: Printing.--To produce resist effects in dyeing textile material with a sulphuric acid ester of a leuco vat dyestuff having an affinity for cotton, the material is first treated locally, e.g. by printing, spraying or stencilling, with an aqueous paste comprising a quaternary phosphonium or a sulphonium compound containing an aliphatic long chain radicle of at least 8 carbon atoms, and is then over-printed or impregnated with a preparation containing the said sulphuric ester and the vat dyeing is developed.  Specified quaternary phosphonium compounds are trimethylcetyl- and trimethyldodecylphosphonium bromides and triethyldodecylphosphonium bromide and specified sulphonium compounds are dimethylcetylsulphonium methylsulphate, benzylcetylmethylsulphonium methylsulphate, dimethyldodecylsulphonium bromide and benzyldodecylmethylsulphonium chloride.  The following examples are specified: (1) Cotton cloth, printed with an aqueous paste containing British gum and dimethylcetylsulphonium methylsulphate is dried and over-printed with an aqueous paste containing Soledon jade green, neutral starch tragacanth thickening and sodium nitrite, and the over-printed material is dried, developed by passage through dilute sulphuric acid at 60 DEG  C. and soaped at the boil to obtain a white resist effect on a ground printed green. (2) Cotton cloth, printed with a resist paste as in (1), is padded in an aqueous solution containing Soledon yellow G and sodium nitrite and is squeezed, developed and finished as in (1) to obtain a white resist on a yellow ground.  (3) Cotton, printed with an aqueous paste containing British gum and triethyldodecylphosphonium bromide, is dried, padded in an aqueous solution containing Soledon jade green, glycerol, gum tragacanth and sodium nitrite, and the padded material is dried, developed and finished as in (1).  Benzyldodecylmethylsulphonium chloride is obtained by reaction of dodecyl methyl sulphide with benzyl chloride.

Title: An improved engine-compressor system for producing compressed air in multicylinder engines
Inventor: NAHODIL ANTONIN
IPC: F04B41/04
Filed: 1965-04-06
Abstract: 1,094,814. Fluid-pressure servomotor systems. AUTOMOBILOVE ZAVODY LETNANY NARODNI PODNIK. April 6, 1965, No.14532/65. Heading G3P. [Also in Division F1] One of the cylinders of a multi-cylinder engine is arranged to function as a compressor cylinder by the manual or automatic operation of a valve 37 controlling a by-pass valve 29 in the fuel supply to the cylinder and a valve 5 in the compressed air delivery channel 4. The automatic operation of the valve 37 is dependent upon the pressure of air in a reservoir supplied by the cylinder during periods operation as a compressor. To operate the cylinder as an engine, compressed air from the reservoir is directed by the valve 37 into pipes 22a, 22b. The air in pipe 22b acts on a diaphragm 34 to close the by-pass valve 29 whereby fuel supplied by an injection pump 23 flows to an injection nozzle 25 instead of to a by-pass passage 28b. The air in the pipe 22a flows to the underside of a piston 6 to cause the valve 5 to close the delivery channel 4. If the pressure in the reservoir falls the valve 37 operates to connect the pipes 22a, 22b to atmosphere so that the valves 5, 29 are opened by springs 7, 32 and-air is drawn into the cylinder through an air pipe 14 and is exhausted through a pipe 15 leading to a cooler 17 connected to the reservoir.

Title: A method and apparatus for collecting waste fibres accumulated in the form of relatively compact masses
IPC: D01G15/78
Filed: 1963-04-16
Abstract: In a cotton card (or each card of a set) "fleece" formed by high-grade waste continually freed by the flats comb falling on to a collecting plate in cohesive form is collected in a trough where it accumulates in front of a suction aperture extending laterally along the bottom of the trough and through which it is periodically removed.  In normal operation, movement of the flats causes spaced groups of pins carried thereby to actuate a ball-valve at predetermined intervals (or such valve may be adjustably controlled by a time control mechanism) whereby an air-piston operates spring-loaded chain and sprocket mechanism to raise a damper plate and connect a source of negative pressure to the aperture and a chamber into which the heaped fibre is drawn; the fibre is then pneumatically removed to a collecting header and a central collecting point.  The recovered fibre may be spread automatically in fleece form.  If the apparatus is incorporated in a conventional suction plant, breaker waste is separately collected.
