Abstract: 710,219. Drawing. KREIDLER, A. May 28, 1952 [June 5, 1951], No. 13495/52. Class 83 (4) A drawing process for the production of accurately profiled bars, pipes or the like is characterized in that the work is subjected to an alternating bending action during reduction. The drawing die 1 is mounted on a holder 2 by bolts 3 and a guide nozzle holder 6 is mounted in a support 5 bolted to the die holder 2. The nozzle holder 6 is formed with a driving pulley 7 and is rotated by a belt drive from an electric motor or from the drawbench drive. In one embodiment a guide nozzle 8, Fig. 2, is displaceable transversely to the drawing axis in a straight guide 6<SP>1</SP> in the nozzle holder 6. The displacement and fixing of the nozzle is effected by set screws 9 and an insert 10 having an aperture corresponding to the cross section of the work 11 I is housed so as to be freely rotatable in the nozzle 8. In operation the work 11 is pushed through the insert 10 and its point through the die 1 the point being seized by tongs (not shown). The guide nozzle 8 is laterally displaced by the set screws 9 so that during the drawing, when the nozzle holder 6 is rotated, the point M, Fig. 1, describes a circular motion around the drawing axis and the work is subjected to a periodic alternating deflection in the die area X. In another embodiment the guide nozzle 8 is pivotally mounted in its holder 6 by bearing bolts 12 and is angularly adjusted by set screws 13, Fig. 4, to enable the rotation of the nozzle holder 6 to impart an alternating bending action to the work during the drawing operation. The diameter of tubes may be reduced by this method without the use of a mandrel.

Abstract: 135,222. Elektro-Osmose Akt.-Ges. (Graf Schwerin Ges.). Dec. 12, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Electric endosmose; electrodes, moving; electrolytes, circulating.-In the dehydration of animal, vegetable, or mineral substances, the material is first forced into a cell of constant volume while water is removed, and is then further treated, with simultaneous diminution of volume of the cell, after cutting off the supply of mat,erial. This diminution may be produced by movement of the electrodes, which may be actuated electrically, pneumatically, hydraulically, or mechanically; their motion may be automatically controlled in accordance with the pressure of charging or with the variation of current as dehydration proceeds. The electrodes 2, 3, Fig. 1, one of which is perforated for escape of water, may form pistons within a ring 4 provided with a charging orifice 5. They may be operated by a hand-wheel 7, worm gear, and right and left handed screws 10, 11, or by toggle gear. In another arrangement, two adjacent cells 1, 1<1>, Fig. 2, each have one electrode 3 or 3' stationary, while the other two electrodes 2, 2<1> are acted on by a spring 12. In the first stage of the process, the spring 12 is held collapsed by the pressure of the material forced in at 5 and 5<1>. In another arrangement, the electrodes 2, 2<1> are forced apart by compressed air. A three-way cock initially directs the compressed air so as to charge the material into the cells, but when the electric resistance of the charge reaches a certain value, a solenoid operates the cock so as to arrest the charging and to move the electrodes.

Abstract: 664,798. Automatic feed weighers. SOUTHALL & SMITH, Ltd. May 18, 1950 [May 26, 1949], No. 14093/49. Class 143. [Also in Group XXX]. Small articles are carried from a hopper α to the weighing receptacles 5 of an automatic feed weigher by a conveyer belt b, a shoot k<SP>1</SP>, a hopper m, a pair of parallel belts p feeding a pair of outlets in the hopper m and a pair of vibratory shoots v located beneath these outlets; and choking of the feed is prevented by automatically stopping conveyer b on the accumulation of a predetermined weight of articles in the hopper m and automatically stopping conveyers p on the accumulation of a predetermined weight of material in the associated shoot v. The hopper m has a pivoted side t which, when moved by an excess weight of articles in the hopper operates a mer cury switch u so energising a solenoid g which disengages the driving clutch e of the conveyer b, and the shoots v each have weight responsive plates z which, through mercury switches 2 and solenoids s, control the driving clutches q of conveyers p. The two shoots v respectively and simultaneously effect bulk and dribble feeds to an empty receptacle 5 supported on a beam 6 and a second receptacle (not shown) supported on another beam and partly filled with the predetermined bulk feed, the vibrators y of shoots v being de-energized by the closing of pairs of contacts 32 by the associated beams after the appropriate receptacle contains the desired weight. During this operation a third container which has previously received both the bulk and dribble feeds in turn, is automatically clamped between a member 43 and a pivoting arm 25 and then tilted to discharge its contents into a shoot 26. When these three operations have been completed a circuit is closed to allow a mechanism, Fig. 2 (not shown), to lift a table 7 together with the receptacles, rotate it through one third of a revolution and lower it so that the empty and part filled pans rest on the beams 6 under the bulk and dribble feed shoots respectively, and the filled pan rests on the arm 25 whereupon the cycle of operations is repeated. The dribble feed shoot v has a step (not shown) arranged obliquely across it, which separates the flow of articles into a single line. In a modification (not shown) this separating is effected by a rotor inserted in the stream of articles and rotating in a direction opposite to the flow of articles. A flap v' impedes the free flow of articles from the bulk feed shoot. In a further modification (not shown) the shoots v are replaced by conveyer belts.

Abstract: 1387286 Editing CBS Inc 27 March 1972 14299/72 Heading G5R An editing system allows desired excerpts from a series of separately recorded video sequences to be "spliced together" by electronically switching between the sequences according to address code information. In the arrangement shown, video sequences from a camera 10 are address coded frame by frame at 14, 16, 18, and then stored in five recorders 22-30. An editor can then operate a light pen 46a and two associated devices 46b, 48 to energize a computer 40 to instruct a control unit 50 to operate any two selected recorders 22-30, and a switching network 56 allows the outputs therefrom to be simultaneously displayed on two monitors 58 70. The editor then reviews each sequence at normal speed or slow motion/still frame rates as required, and chooses edit points at which an excerpt from one sequence is to end and an excerpt from another sequence is to begin, the address codes corresponding to each edit point being noted and stored in the computer. A composite programme at normal speed with all the excerpts "spliced together" can then be produced by operating all the recorders 22-30 and using the stored edit point addresses to switch one excerpt after another on to a common display. Details concerning the "hunting" and "searching" operations carried out by the computer during the "splicing" are discussed with reference to Fig. 6 (not shown). By using a further recorder 31, an editor may make a copy of any sequence stored in the other recorders 22-30, whereupon two excerpts from different stages of the same sequence may be reviewed and joined together. A rapid access disc file system is described with reference to Figs. 5A, 5B (not shown).
