Title: Method for the manufacture of a hose
Inventor: MARTIN EDWARD HERBERT ERHARD
IPC: F16L11/08
Filed: 1967-08-11
Abstract: 1,205,983. Hoses. DUNLOP CO. Ltd. 6 Aug., 1968 [11 Aug., 1967; 9 March, 1968], Nos. 36902/67 and 11611/68. Heading F2P. A method of manufacturing a hose comprises forming a sheet 1 of elastomeric material, e.g. polyvinylchloride or polyurethane, having a layer 4 of longitudinal fibres, e.g. nylon, embedded therein, seaming together the longitudinal edges of the sheet 1 to form a tube, providing at least one layer 10 of transverse fibres, which cross the longitudinal fibres 4 within the finished hose, e.g. at a bias angle of 88 to 90 degrees, and which are preferably first coated with a soft composition of an elastomer and treated with a bonding agent, and then embedding the transverse fibres, in a layer of soft composition of an elastomer, e.g. P.V.C., on the outer surface of the tube, and setting the soft composition. The edges of sheet 1 are seamed together, e.g. by dielectric or ultrasonic welding, the sheet preferably being extruded through a die with serrations for the reception of the longitudinal fibres 4 which are preferably embedded near the outer surface of the tube. Alternatively, the sheet may be prepared by applying a soft composition of an elastomer to a sheet of an elastomeric composition, laying longitudinal fibres down in the soft composition which is then allowed to set. Before laying, the fibres 4 may be passed through a bath of soft elastomer, or through an extrusion nozzle with a soft elastomer. In another method, the sheet may be prepared from a sheet of aligned fibres bonded together by a soft composition of an elastomer, a layer of soft composition of an elastomer being applied to the sheet of fibres, e.g. by colendering, the soft compositions being finally set. The layer of transverse fibres may be formed by winding a strip of tyre cord fabric on to the tube. Any of the vulcanizable elastomers conventionally used for hoses may be used, e.g. natural rubber, neoprene, nitrile rubber, but preferably each of the elastomers is a thermoplastic material, e.g. an ethylene/vinyl acetate polymer or a thermoplastic block copolymer. As shown, a P.V.C. sheet 1 is passed, in succession, through a spreading station 2, a roller 3 with fibres 4, and a heating station 5 and then through a seaming device 6 where the sheet is formed into a tube before passing over a mandrel 8 which is supplied with air through a duct 9 in order to reduce friction between the tube and the mandrel. Transverse fibres 10 are wound on to the tube at a winding station adjacent a second P.V.C. spreading station, 11, and the tube finally passes through a heating station 12, a further P.V.C. spreading station 13 and a final heating station 14 to a draw-off station 15.

Title: Improvements in adjustable moulds for the manufacture of tiled fireplace surrounds and other articles
Inventor: ALDAM KENNETH SAMUEL
IPC: B28B7/02
Filed: 1952-05-12
Abstract: 722,929. Moulding tiled fireplaces &c. ENGLISH FIREPLACES (WIMBLEDON), Ltd. Aug. 6, 1953 [May 12, 1952]. No. 11969/52. Class 87 (2). A framework for moulding articles such as fireplace surrounds comprises at least two frame members of L-shape or U-shape in plan, each with two legs and an included right angle and each leg comprising a base flange and a vertical support flange, the vertical flange of one or more pairs of legs being held in end-to-end alignment by means which provide for end-to-end adjustment while preserving alignment of the flanges. The moulding framework is built up on a slabbing bench 13, with an inner framework 14 which may also be an adjustable framework according to the invention. Tiles 15 are laid glazed face downward on the slabbing bench, and boundary tiles 16 are laid with their edges on the bench and with their glazed faces against the outer frame members. Cement is then filled in between the unglazed faces of the tile, in which may be incorporated metal reinforcement 18. One form which the adjustable moulding framework may take is shown in Fig. 1 where it comprises three members all of L-section material, the members 2, 3 having a long and a short leg each and the member 1 having two short legs 1a, 1b which align with the short legs 3a, 2a of the members 3 and 2. Aligning rods 9 pass through holes in gussets 8 and may be slidable in all the members or welded to one of them, e.g. the rod 9 may be welded to the leg 1a so that the leg 2a slides on it. The overlap 3c provides for adjustment one way; the gap at 6 caused by adjustment the other way can be closed by a filler plate. In another arrangement the framework may comprise four similar members each including a right angle. Instead of the rods 9 sliding in holes, the gussets may be slotted so that the rods may be dropped in place. Instead of gussets, eyes of conventional form may be screwed or welded to the horizontal flanges to enclose the rods. Instead of rods 9, aligning members of channel section may be used which slide over rectangular lugs on the flanges, or a rectangular section rod welded to the vertical flange of one member may slide into a channel in the vertical flange of the other member. The vertical flanges may be reduced in thickness for some distance from their ends so that they can slide over one another for that distance, and a stud may be fixed on one flange to slide in a slot in the other. Fig. 6 shows an arrangement of two U-shaped frame members, each with two channelsectioned legs welded to an L-shaped base side. The legs are aligned by base 35 which fits closely in the channels. Spring clips may be used with the various aligning means to hold them in place by friction. Straight extension or gap pieces 19 may be used to extend the size of the framework, as shown diagrammatically in Fig. 12.

Abstract: 433,442. Light-valves. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Perreault, G. E. ; 25, Park View Avenue, Bronxville, New York, U.S.A.) April 18, 1935, No. 11981. Convention date, April 27, 1934. [Class 40 (iii)] The polepieces 5, 9 of an electromagnetic light-valve each have a pair of opposed adjustable light masks 16, 19 with their inner ends spaced to provide light-transmitting slits, which are superposed at an angle to define an aperture, and at least one pair of masks can be rotated about its polepiece to vary the angle between the slits. The inwardly extending opaque masks 16, 19 are carried by yokes 22, 23, 18, which are rotated about their respective polepieces 5, 9 by adjusting- screws 24, 25, 34. The spacing between each pair of masks is varied by adjusting-screws 29, 35. The vibratory ribbon R is fixed at one end 42 and the other end is tensioned by a spring-controlled lever 40. The lever is secured to the inner end of a spiral spring 47, the outer end of which is adjusted to regulate the tension of the ribbon, Fig. 4 (not shown). The length and material of the spring are so arranged that variations in its length due to changes in temperature move the lever by an amount equal to the movement of the ribbon caused by such changes, thus maintaining the tension constant. The lever is balanced statically to avoid alteration of the tension when the valve is jolted. The ribbon is supported near the lever by pulleys 38, 39, which enable the ribbon to move freely longitudinally.

Title: Improvements in or relating to vacuum brake systems
IPC: B60T13/46
Filed: 1959-04-09
Abstract: 855,220. Vacuum braking systems. KNORRBREMSE G.m.b.H. April 9, 1959 [Nov. 19, 1958], No. 12015/59.. Class 103 (1). A vacuum braking system includes a first train pipe, the degree of vacuum in which operates a control valve device controlling the exhausting of, and supply of air to, one chamber of a two-chamber brake cylinder, and a second train pipe maintained at constant vacuum and connected to said one chamber by the valve device for brake release. On braking, a decrease in vacuum in train pipe 1 acts in chamber 5 of the control valve device to lower diaphragm 7 to open valve 31 and connect atmospheric chamber 37 to the lower brake cylinder chamber 43 via pipes 41, 51, causing piston 45 to rise and apply the brakes. For brake release, a rise in vacuum in train pipe 1 causes diaphragm 7 to rise, due to atmospheric pressure in chamber 9, to open valve 15 and connect lower chamber 43 to train pipe 63 and reservoir 61 via pipe 51, chambers 23, 21, one-way valve 54, pipe 59 and cock 65 for rapid exhaustion of chamber 43 and rapid brake release. The upper chamber 47 is maintained evacuated by reservoir 53 and by train pipe 63 via one-way valve 57, pipe 59 and cock 65, the chambers 43, 47 being connected via one-way valve 49 which is such as to maintain a slightly higher pressure in chamber 47 to bias piston 45 down. If a truck with this apparatus is connected in a train not equipped with a second train pipe 63, the cock 65 is rotated through 90 degrees to isolate train pipe 63 and reservoir 61; on brake release and opening of valve 15 the chambers 43, 47 are connected via pipe 51, chambers 23, 21, one-way valve 54, pipe 59, cock 65 and pipes 67, 55, to equalize the pressure in chambers 43, 47 and release the brakes, the system being evacuated through valve 15, chamber 21, pipe 25, one-way valve 27 and train pipe 1.

Title: Improvements in or relating to conveying machines
IPC: B65G49/04
Filed: 1961-04-05
Abstract: 911,882. Conveyance of articles through liquid baths. UDYLITE RESEARCH CORPORATION. April 5, 1961 [April 7, 1960], No. 12258/61. Class 78 (1). In apparatus, Fig. 1, for treating articles in a sequence of liquid baths 14, the articles are contained in racks 28 carried by carriers 26. The carriers run on fixed rails 22 and on movable rails 24. Horizontal movement is effected by pivoted pawls 36 carried by reciprocating bar 32. Bar 32 and rails 24 are carried by chassis 16 which is elevated periodically by a piston-and-cylinder to effect the vertical movement of a carrier 26 from bath to bath. The elevating movement, Figs. 2 and 3.-This is effected by two endless chains 68 driven by motor 88 and supporting the rack 28 at 82 as shown in dotted lines. Chains 68 are carried by frame 42 pivoted to the edge of a bath 14a at 44. The pivoting movement of frame 42 about pivot 44 enables a carrier 26, when on rail 24 in the elevated position, to be progressed along the said rail 24 by means of reciprocating bar 32 without the carrier running foul of frame 42. As the carrier, therefore, moves along the elevated rail 24, cam 58 on reciprocating bar 32 causes frame 42 to pivot slightly to allow the carrier 26 to take up position ready for its rack to be caught by lugs 82 of the chains 68 and to be caused thereby to descend into bath 14a. As the carrier 26 is raised on rail 24 by the elevating chassis 16 it operates either switch LS6 or LS7 by means of a trip 116 which is carried by the carrier and has been previously set by an operator. Accordingly the circuit of motor 88 is prepared to operate chains 68 to give the work rack either a " non- dip," a delayed dip (i.e. a short dip) or a normal dip. Operation, Figs. 6-9.-The dip begins as shown in Fig. 6, with carrier 26 and rack 28 in the elevated position and the chain lifters 77 (and lugs 82) at rest. Lifters 77 seize rack 28 and lift it off carrier 26 and move to the position of Fig. 7. Here the rack remains, in the case of a " non-dip," whilst chassis 16 (and carrier 26) perform a descent and a rise, ready for the reversal of the lifters to transfer back the non-dipped rack 28 on to its now-waiting carrier 26. In the case of the delayed dip, after a timed interval, the lifters carry the rack downwards from Fig. 7 into the bath, i.e. to Fig. 8, and then lift it up to the position of Fig. 9. The lifters are then moved finally to the position of Fig. 6 to drop the rack back on to the carrier 26.
