Title: Method and apparatus for manufacturing a belt
IPC: B23G5/12
Filed: 1958-09-22
Abstract: 866,684. Moulding rubber belts. GOODYEAR TIRE & RUBBER CO. Sept. 22, 1958 [March 24, 1958], No. 30165/58. Class 87(2). [Also in Group XXIV] In the manufacture of an endless toothed driving belt comprising tension cords 16, Fig. 14, of wire or fabric and a toothed section of rubber or like vulcanisable material 7 covered with fabric 6, a flat composite sheet of unvulcanised rubber or the like and impregnated stretchable fabric is placed over a flat or cylindrical toothed matrix 1, Fig. 5, and subjected to warmth and pressure which causes the rubber to flow, still vulcanised, into the grooves between the matrix teeth, thereby stretching the fabric to line the grooves. The rubber and fabric layers 7, 6 may or may not be bonded together before pressure is applied. Pressure is applied to a flat matrix through a press platen, with the interposition of a lubricant or a sheet of material, such as polymerised tetrafluoroethylene, to which the rubber will not adhere. The matrix is preferably sprayed with a silicone or other lubricant. In order to make the fabric 6 stretchable the weft cords are crimped or coiled, and may be of twisted and heattreated nylon. The warp cords are preferably straight. Alternatively a stockinette material, which may be bias laid, may be used. The toothed strip 6-7 is laid around a grooved drum and its ends lap or butt-spliced. A lap splice may be effected, Fig. 16 (not shown), over a toothed flank so that the tension cords are not deflected. The tension cords are wound on the drum and covered with a layer of rubber 17, Fig. 14, and possibly a fabric cover 18, before the drum is placed in a vulcanising mould, Fig. 10 (not shown) and subjected to a curing medium such as steam, and to pressure exerted through a rubber diaphragm. The vulcanised band is then placed on a rubber-covered mandrel for cutting into belts. In a modification the flat matrix 1, Fig. 5, is replaced by a grooved cylinder to which pressure is applied hydraulically by a bladder in a drum, Fig. 11 (not shown), which may be mounted for movement over the cylinder. Vulcanisation is subsequently effected in a separate drum.

Title: Improvements in or relating to machines for capping vessels with beaded mouths
IPC: B67B3/02
Filed: 1931-11-03
Abstract: 371,291. Bottle - capping machines. CROWN CORK & SEAL CO., Inc., Highlandtown, Baltimore, U.S.A.-(Assignees of Booth, G. W. ; c/o Crown Cork & Seal Co., Inc., Highlandtown, Baltimore, U.S.A.) Nov. 3, 1931, No. 30448. Convention date, July 27. [Class 125 (ii).] A machine for capping bottles &c. comprises an expansible, segmental throat, which irons a substantially flat disc over the bead from the top thereof to its widest part without touching the extreme edge of the disc, which buckles under the bead. Each segment 23 has a flange 24 which rocks about a split ring 29 which may be integral with the flange, resting on housing 28, and the segments are held yieldingly together by a spring 30. In a sleeve 47 carried by an arm clamped on the standard 45 works a tubular member 50 recessed below the sleeve 47 to accommodate the housing 28 and having a collar 56 supporting a supply hopper 55. A presser tool 20 is connected by a ball-andsocket joint to a stem 19 encircled by a spring 21 which presses against a plug 52 in the member 50 and an abutment 53 on the stem. A disc is fed below the tool 20 by a slide plate 61 having a recessed end and being connected to the stem 19 by links 73, levers 74 pivoted at 75<1>, links 78 and a yoke 77. Vertical move. ment is imparted to the member 50 via a rack and pinion by an arm 18 mounted in the sleevecarrying arm. In Figs. 2 and 3 the member 50 is shown in its uppermost position. A disc rests on an annular guide 18 hinged at 64 to the slide rest plate 58 and held in position by a hook 69 engaging a projecting screw 70 which supports a plate 71 which limits movement of the disc to the right, When the member 50 is depressed the tool 20 presses the cap on the vessel, which is centred by leaf springs 72, and on further downward movement the throat 23 expands, ironing and buckling the margin of the disc around and under the bead, the stem 19 moving upward relatively to the member 50, thus moving the slide to the left, the stack of discs dropping. When the member 50 is raised the stem moves downward relatively thereto and the slide moves to the right, positioning a disc under the tool 20. When the slide is to the right a lever 87, pivoted on the collar 56 is held as shown by the engagement of its short arm with the sleeve-carrying arm, but when the member 50 is depressed and the slide 61 thus moved to the left the short arm is disengaged and the long arm is spring-pulled down, a shoulder thereon moving into the path of a stud on a lever 74 and locking the slide into the left-hand position. Relative movement between the vessel and the throat may be obtained by moving either, by hand or power.

Title: Method of and apparatus for re-starting warp knitting machines
IPC: D04B27/14
Filed: 1976-07-22
Abstract: When a warp-knitting machine is put into operation, shortly before the machine is started up the already pretensioned warp threads (18) are subjected to an additional force, in order to avoid differing stitch sizes in the fabric. For this purpose, the warp-knitting machine is provided with a servomotor (1) for actuating thread-deflecting rockers (14), via which the additional force is applied to the warp threads. The servomotor is put into operation, together with the main drive motor of the knitting machine, via a circuit closer (7) actuable by hand and drives a control device containing cam discs (3, 4, 5), one of the cam discs being intended respectively for actuating the said thread-deflecting rockers, the circuit closer of the main drive motor and the circuit breaker (9) of the servomotor. The application and cancellation of the additional force are fixed relative to the switch-on time of the machine by adjusting the cam discs. <IMAGE>

Title: Improvements in and relating to regulating arrangements for systems comprising motive gas generators and machines driven thereby
IPC: G05D13/00
Filed: 1936-11-09
Abstract: 484,912. Gas turbines. PESCARA, R. P. Nov. 9, 1936, No. 30589. Convention date, Nov. 8, 1935. [Class 110 (iii)] [Also in Group XXVIII] A turbine &c. 6 is supplied by a free-piston gas generator comprising compression cylinders 4<1> supplying a tank 5 which delivers scavenging and combustion air to the combustion cylinder 2, the exhaust gases of which, and the scavenging air, pass through a conduit 8 to the turbine &c. The pressure in the conduit 8 acts on a piston 13 to regulate the amount of fuel delivered by a pump 14, through a cam 15. At starting &c. excess gas escapes by a valve 16 opened by the rod of the piston 13. Alternatively the amount of gas delivered at starting &c. may be diminished by causing the piston 13 to open a relief valve on the compression cylinder, or a byepass may be provided between the tank and the turbine &c. having a piston valve which at the lowest pressure delivers the air to atmosphere, and at medium pressures to the turbine &c. in diminishing amounts, the valve finally closing. In a modification, the cam 15 is under the joint control of the speed governor of the turbine &c., which may act through a fluid relay, and of the pressure in the conduit leading from the compressor to the tank. In a second modification, the pressureresponsive element 13 may be a bellows regulating the position of a variably slotted member, while the speed governor acts through a relay on a lever controlling the fuel pump, the travel of the lever being limited by the variable slot. Fig. 9 shows a device in which the fuel pump is controlled by the speed governor 28 of the turbine &c. 6 acting through a relay 32 on the cam 15 which is also controlled by the piston 13 acted on by the turbine supply. This piston also acts through levers 46 to vary the position of the fuel jets as described in Specification 476,386, and further controls the positions of a lever 43 through which the fuel pump is driven and a valve 20 allowing escape of air to atmosphere during idle running and starting periods. A valve 48 on the supply conduit of the turbine may be normally held closed by the lubricating oil pressure acting on a piston 50, which pressure falls on dangerous acceleration of the turbine, allowing the valve to open ; the valve may also be opened manually.
