Title: Improvements in hydropneumatic presses for riveting, punching, welding and the like
IPC: B21J15/22
Filed: 1937-06-22
Abstract: 495,342. Hydraulic presses; hydraulic intensifiers; valves ; pipes. BOURSET, R. June 8, 1937, No. 15922. [Classes 69 (ii) and 135] [Also in Group XXVIII] In a hydraulic press for riveting, punching, electric welding, &c. comprising pistons 1, 7 operated pneumatically for producing the approach and pressure movements respectively, the low pressure liquid supplied by piston 1 passes from a chamber 5 through a stationary conduit 8 in the bore of the rod of piston 7 and through ports 15 in a tubular valve 13a, abutting the end of conduit 8, into the pressure chamber 10. At the end of the approach movement thus performed air is supplied to the piston 7 the rod 7a of which moves forwardly to close the ports 15 and thereafter carries the valve 13a with it whilst applying a high pressure to the liquid in chamber 10 and effecting the working stroke. Piston 7 and the press piston are returned by springs after the air supply is cut off, the valve 13a being moved initially by liquid pressure until it abuts the end of conduit 8, when further movement of the rod 7a uncovers the ports 15 and permits flow of liquid through the conduit to return piston 1. Spring stops 16 maintain the valve in its returned position. Valves 34, 35, Fig. 3, controlling air supply conduits 3, 9 for the low and high pressure pistons respectively, are operated successively by a compressed air supply 39 acting on push members 37, 38. The air pressure acts initially on member 37 to actuate valve 34 and leaks past a reducing valve 52 into cylinder 38b where it gradually builds up a pressure which eventually moves piston 38 thereby opening a valve 50 on the air supply 39. The valve 52 is adjusted so that the high pressure piston air supply is opened at the end of the approach stroke. In an alternative arrangement the air control valves 69, 80, Fig. 5, are operated successively by links 77, 79 from a hand lever. The links bear on thimbles 74 arranged to move different distances before opening their respective valves. A ring 27 in the cylinder 6 can be moved axially to limit the stroke of the piston 7. The initial position of piston 1 is adjusted a screwed rod 25. In a modification the piston 1 is of single diameter and cylinders 2, 6 are formed in one piece. A flexible steel pipe connecting the press and tool cylinders comprises short lengths connected by ball and socket joints 83 and a swivelling joint 91 having a packing member 93. The end pipe lengths are rotatably mounted in the respective cylinders.

Abstract: 625,111. Rubbing-collar seals for shafts STEVENS, A. H. (Crane Packing Co.). May 27, 1946, No. 15987. [Class 122(v)] A seal between relatively movable elements consists of an axially resilient bellows member 15 having radial flanges 20 which are pressed against a sealing ring 16 and an impeller 13 of a pump 10 by means of a helical spring 24, the ends of which bear against rigid washers 22 having internal flanges 23 to retain the spring 24. The sealing ring 16 which engages a flange 14 of the impeller 13 slides against a stationary member 19, thereby preventing leakage. Fig. 2 shows a modified sealing member 25, the tapered end of which is in contact with the rotating shaft. The inturned edge 29a of a washer 28 exerts a compressive force upon the member 25, thereby effecting a seal with the shaft 12. The bellows may be outside the spring and have its end flanges 20 on the inside and pressure reinforcing rings be disposed in the folds of the bellows to prevent deformation thereof under high pressure. To centre the bellows, lips may be provided on the sealing ring 16 and the impeller 13 respectively.

Title: Improvements in or relating to a method of and apparatus for producing a composite web of fibrous textile material
IPC: D04H1/74
Filed: 1965-04-15
Abstract: A continuous composite web is produced by piling a single continuous web of fibres (supplied, for example, from a drawing frame) severing the web to separate each layer from the succeeding layer, and continuously advancing the pile as a web with the compacted layers in staggered or overlapping relationship.  The initial web is conveyed by horizontal belts into an accumulator box wherein it is received by a pair of belts which convey it through, and to the lower end of, an arm which is oscillated about an upper pivot so that the discharging web is distributed on a sloping, arcuate floor.  The arm, at each limit of its stroke, operates a spring-loaded cutter blade to sever the web so that successive, separate, superposed lengths accumulate. An air valve is operated by, and in synchronism with, the movement of the arm to direct streams of air (from one or the other of two distribution chambers attached to opposite sides of the arm) on to each severed layer to urge it against the pile.  The composite web is pulled forward and compacted by adjustable nip rollers at a speed which is determined so that the trailing edge of a first layer deposited is just leaving the box as the leading edge of the Nth layer just deposited becomes part of the web which therefore proceeds as the resultant of N superposed layers.

Abstract: 368,618. Centrifugal machines. GUTEHOFFNUNGSHœTTE OBERHAUSEN AKT.-GES., Oberhausen, Rhineland, Germany. June 4, 1931, No. 16378. Convention date, Aug. 14, 1930. [Class 23.] A centrifugal machine for drying sludge and granular material has a cylindrical drum a, and a disc b capable of moving axially and rotating with the drum. The drum wall carries tubes e for the discharge of liquids, or the drum wall may be perforated ; the liquids pass into the chamber f from which they are drawn by the pipe g. The disc b, which is operated axially by hydraulic or pneumatic means controlled by the valve w, carries a distributing plate b<1>, the disc and plate being arranged with a gap c between them. With the parts as shown in Fig. 1, the sludge is supplied through the valve d to the top of the plate b<1> and the plate b<1> is descending. A layer of material is thus formed against the wall of the drum a to dry, and the material previously dried beneath the plate is expelled from the lower part of the drum into the funnel t. At the end of the stroke the disc b and plate b<1> move upwards and the material is supplied from the valve d to pass through the gap c between the plate and the disc. It thus forms a layer on the drum wall below the disc and it passes through the drying process while the dried solids in the upper part of the drum are raised by the plate b<1> and discharged over the top of the drum. The process is repeated, material being supplied alternately above and below the disc, and a washing liquid may be supplied through the valve d<1>. The tubes e may be replaced by elongated nozzles, and the drum may be bevelled internally to assist the liquid to flow to the discharge tubes or nozzles.

Fatty oils, sulphuretted.-A process for colouring rubber substitutes made from fatty oils consists in mixing an emulsion or suspension of the rubber substitute with aqueous pastes of organic or inorganic water-insoluble colouring materials, or with dry pigments, colour lakes, waterinsoluble metal salts of organic dyestuffs, or mixtures thereof, or with leuco compounds of vat dyestuffs, or forming the water-insoluble colouring material, e.g. a colour lake, in situ, and simultaneously or subsequently coagulating the coloured material. The quantities of initial materials may be so selected that a solid coloured emulsion is formed. The emulsion may be made with the aid of wetting agents. In examples (1) vulcanized rape-seed oil is emulsified with an aqueous solution of the sodium salt of propylnaphthalene, sulphonic acid, and an aqueous paste of the leuco compound of Algol Red B is added. After passing air through the mixture, the coloured oil is coagulated by adding a dilute solution of formic acid or alum; (2) a pasty suspension made by mixing factice with bleached linseed oil, is kneaded with an aqueous paste of cadmium yellow and di-butyl naphthalene sulphonic acid to form a solid coloured emulsion. The coloured materials thus produced may be used for colouring rubber and other plastic materials. Specification 321,693 is referred to.
