Title: A method of and apparatus for electro-magnetically deforming metal
IPC: C21D7/13
Filed: 1963-08-09
Abstract: 1,021,150. Stamping. DEUTSCHE EDELSTAHLWERKE A.G., and ALLGEMEINE ELEKTRICITATS-GESELLSCHAFT. Aug. 9, 1963 [Aug. 31, 1962], No. 31588/63. Heading B3Q. A method of electromagnetically forming a metal workpiece 2, Fig. 1 (not shown), comprises reducing the resistance of the metal by inductive heating and then electromagnetically forming the heated work. The work is enclosed in a divided die 4, the parts of which are electrically insulated from each other, as by oxidization. An induction heating coil 1 in the work, which is also used for carrying the forming pulse, is connected to a medium-frequency supply 8, Fig. 2 (not shown), or the mains network, through switches 5, 7. A battery of condensers 6 is included in the circuit. After the aluminium work has been heated to about 400 C., switch 5 is opened and switch 7 operated to charge the condensers 6 from a transformer 9, through a rectifier 10 and a resistance 11. The condensers are then discharged through a switch, ionised-gap discharge vessel or a spark gap 12 to the coil 1 for effecting the forming operation. Instead of a transformer, a voltage doubler or multiplier may be used. In a modification using a high-frequency generator, Fig. 3 (not shown), the transformer and rectifier are omitted. The work 2, die 4, 4<SP>1</SP> and the coil 1 may surround the core of a magnet, Figs. 4 and 5 (not shown), having a removable keeper 15. Fig. 6 (not shown) depicts graphs of the power required for deforming the metal at various temperatures, the power required for raising the work-temperature in a given time, and of the sum of the other two graphs, showing the minimum power requirement.

Abstract: 430,077. Cutting pile fabrics. PATENTVERWERTUNG Dr. M. GUNTHER GES., 18, K÷penickerstrasse, Berlin. Nov. 13, 1933, No. 31590. Convention date, Nov. 14, 1932. [Class 31 (i)] A machine for cutting double or multiple velvet by means of an endless band knife 10 has the upper feed roller 4 driven at a lower speed than the lower roller 2 so that the pile threads are inclined and stretched when presented to the knife. The reduced speed may be obtained by a band brake or by mechanism. The fabric passes between a plate 8 and the table 1 to limit the expansion of the threads after leaving the feed rollers ; the plate 8 is adjustable up and down, and the knife guide 11 may be connected therewith to move by half the adjustment. The draw-off rollers 18 deliver the two portions of fabric compressed together.

Abstract: 1,210,814. Valves. I. J. TAYLOR. 25 March, 1968 [12 July, 1967], No. 32052/67. Heading F2V. An isolating valve for high vacuum applications comprises a piston 42 movable by a crank pin 35 carried by a disc 25 rotatable by lever 32. An 0-ring 47 is carried at the upper end of the piston in a groove defined by an undercut control projection on the piston and a crimped peripheral projection. The 0-ring co-operates with seat 16, and stops (48, 49) on cover 27 limit rotation of the lever such that the extreme positions of the piston correspond to deadcentre positions of the crank pin. A V-shaped groove in cover 27 houses a sealing ring and a pin 9 prevents rotation of the piston.

Abstract: 776,080. Feeding articles. FLETCHER, R. F., LANDI, M., BURR, H. C, POCOCK, A. G., and KIRK, C. R. Nov. 4, 1955 [Nov. 5, 1954], No. 32112/54. Class 117 [Also in Group XVII] A bottle capping appliance comprises a magazine for a stack of caps 1, a mounting 8 hinged to the magazine and containing a suction operated extractor for removing the caps successively from the magazine, hand operated means for effecting angular separation of the mounting from the magazine to expose the extracted cap for application to the bottle, and means to reduce or break the suction to release the cap. The magazine has annular base plates 3, 3a between which a rubber ring 7 is gripped and from which extend rods 2 surmounted by. a circular disc 4 held in position by a leaf spring 5. The base plate 3a has a rectangular extension by which the magazine is fixed to a crossbar 14 integral with a block 20 and having handles 25. Through lugs 19 on the block 20 passes a pivot pin 18 having at one end a cylindrical head 17 and at the other an eccentric disc 28, to which is pivoted a housing 8 with a depending cylinder 9 and a fixed cap 10. Inside the cylinder 9 is a piston 29 acted on by a coil spring 30 and having a slightly thickened upper end supporting a rubber ring 36 and with holes 34 leading from insde the piston to an annular recess 35. Passages 33 and 18b, the latter through the pivot pin 18, lead to an adaptor 32 through which suction is applied to the interior of housing 8. A resilient ring 37 shaped so as to engage the rim of a bottle to be capped is fixed between the housing 8 and the cap 10 and held in position by a coil spring 39. Thick elastic, clamped between a screw 15 and the crossbar 14 and passing round a pin 16 on the cylinder 17, tends to keep the hinged parts of the appliance together, abutments 11 on the cap 10 spacing the magazine from the cylinder 9. A U-shaped lever 22 is pivoted at the base of the U to lugs 24 on crossbar 14 and a cable 27 fixed to and wound round the eccentric 28 is attached to limb 22a of the lever. A valve 41 controlling the entry of air to passage 42 communicating with passage 33 is attached to the cylinder 9 and is arranged partially to be opened by abutment with part 43a of member 43, fixed to the block 20, when the magazine and cylinder are pivoted apart. In operation suction is supplied to the cylinder 9 through the adaptor 32 causing a single cap 1 to be drawn against the cylinder head and the cylinder to be retracted against the action of spring 30; the cylinder is then pivoted clear of the magazine by pressing handle 32 and suction is slightly reduced as described above to prevent buckling of the cap; the cap is nipped against the bottle head by distortion of member 37 against the pressure supplied by the spring 39 and finally suction is released by completely opening valve 41. In a modification, not shown, a large boss is provided in the cylinder head to assist prevention of buckling of the cap.

Abstract: 1518118 Storage body refuse packer SARGENT INDUSTRIES Inc 1 Aug 1975 [12 Aug 1974] 32348/75 Heading B8E A refuse vehicle 4 loaded from the front end by arms 12 has a compaction panel 76 for compressing refuse towards the front wall which panel is provided with stuffer panels 90 to apply greater pressure to effect greater compression. Doors 30 are provided to close the inlet during compression and these can form windshields during the emptying of the refuse container 24. The loading arms 12, Figs. 1, 2, are pivoted about 14 by rams 16 and have fork arms 18 pivoted to their other ends at 20 which are actuated by rams 22 to engage slots 26, so that by the hydraulic circuit arrangement the container is lifted in a horizontal position until the opening is reached and then extension of the rams 22 tips the contents into the storage body 10. Doors 30, Fig. 5, are raised to an open windshield position by rams 56 which by the hydraulic circuit are caused operate as the arms 12 rise and are closed with a positive force to push the refuse down aided by sharp edges 75 which give a shearing effect. The compaction panel 76 is in its retracted position, Fig. 6, during loading and is caused to slide towards the front wall guided by shoes 108, 109 in guide slots 100 by a ram 84. The panel has an extension scraper plate 118 and both have inclined faces to provide an upwards component of compressive force. The operating hydraulic circuit is such that when a predetermining force has been applied by the plate 76 rams 94 are extended to move the stuffer panels 90 forward of the face 131, Fig. 9, of the panel to cause further compression and voids in the refuse. This action reduces the pressure on the plate 76 which then is advanced further. These alternate actions continue until maximum compression occurs. The tailgate 32 normally sealingly held against the body 10 by latches 136 can be unlatched and raised, Fig. 1, by rams 130 to allow discharge of the load by the panel 76. The tailgate contains a well to collect liquid expelled by the compression. The hydraulic circuit described effects the operations above but a modified arrangement employing a modified door and separate windshields is described where an independent circuit is provided for the operations of the closure door.
