Abstract: 1294078 Compacting metal powders W BUSSMANN K G MASCHINENFABRIK and MANNESMANN PULVERMETALL GmbH 8 April 1970 [24 April 1969] 16733/70 Heading B5A In an hydraulic press for compacting metal powder which comprises an upper press cylinder 9, an oppositely acting lower press cylinder not shown, on a means for feeding powder to a metal die, the stroke of the upper cylinder piston is limited by an adjustable two part stop sleeve 7 disposed within the cylinder 9. Sleeve 7 is located in cylinder 9 by a buttress thread 22, and is rotated by a gear 3 acting through a stuffing box 5 and key 6. Gear 3 is drawn by a worm 2 and electric motor 1. To indicate the position of the stop 7, a microswitch 15, on the outside of the press, moves on a column 15 rotated by a further worm and wheel 12, 13. A column 16 moves in unison with the piston and carries a stop 17 which acts with the switch 15 to light a lamp when the piston and sleeve 7 engage other. The switch 15 carries a cam 18 to engage limit switches 19, 20 to de-energize the motor 1 at the limits of travel of the key 6. The sleeve 7 can be formed in one piece.

Title: Magnetic Writing Board
IPC: B43L1/00
Filed: 1968-04-11
Abstract: 1,168,217. Repeatedly-usable writing boards. INTERNATIONAL BUSINESS MACHINES CORP. 11 April, 1968 [22 May, 1967], No. 17447/68. Heading B6P. A magnetic writing board has a number of cavities 14 exposed to view at least at one surface of the board, and each cavity contains a slug 15 or 16 of magnetizable material, each slug having one face which contrasts in colour with the board, and each cavity having a permanent magnetic field arranged to hold the slug in either of two possible positions, so that in the first position 16 the slug is adjacent to the surface of the board and its contrasting surface is exposed to view and in the second position 15 the slug is displaced from the surface and its contrasting surface is hidden. As shown in Fig. 3, the cavities 14 are formed in laming 19, 21, the lamina 19 being of non-magnetic material attached to a backing lamina 20 of magnetizable material, and the lamina 21 being magnetized with the polarity as shown. A transparent lamina 13 of non-magnetic material covers the cavities 14. The slugs are permanently magnetized with the contrasting colour face at the south pole, the colour at the north pole being that of the board surface. Normally the magnetic field of lamina 21 causes the plug to assume position 15. If, however, a stylus with a north pole at its point and having a strong magnetic field is moved over the surface 13, the slugs along its path are moved from position 15 to position 16, so that the path is exhibited on the surface. If a magnetic eraser of opposite polarity to the stylus is moved over the surface 13, the slugs 16 are restored to the position of slugs 15. In a modified construction (Fig. 4), the cavities are formed by two magnetized laminµ separated by a non- magnetic lamina the operation occurring in a similar manner to that described with reference to Fig. 3. In this form, the bottom lamina corresponding to lamina 20 may be transparent so that a reverse image may be seen at that face of the board. Further, the slugs may not be permanently magnetized, the induced magnetism therein being sufficient to produce the required movement thereof. A board may be formed of a number of panels 10A, 10B, 10C, having interfitting configurations 11, 12 at their edges.
Patent GB-175385-A (GB)
Abstract: 175,385. Goddard, J. W., and Bentley, P. A., (trading as Bentley Engineering Co.). Nov. 12, 1920. Circular machines.- Machines with coaxial opposed needle - cylinders are provided with splicing or yarn-changing mechanism comprising guides which are movable in or out of the range of the needles in a plane substantially perpendicular to the cylinder axis, and yarn-cutting and gripping mechanism. The striping yarns are carried by guides 1, 2 retained by a cover 4 in a substantially radial slideway formed in a bracket 3. The splicing-guide 5 is mounted, preferably pivotally, on the plate 4 and is operated by a bell-crank 10, the upper end of which by striking a pin 19 pro-. jecting from the guide 5 moves it from the position shown in full lines to the position shown in Fig. 3 in dotted lines. A spring 9 attached to a tail 9<a> of the guide 5 retains it in either extreme position. The end of the lower bell-crank arm 20 is seated in a plunger 21 resting on a lever 22 which carries a cam-piece 26 acted on by a cam 24 on the control drum 23. When the piece 26 rides off the cam 24 the upper end of the lever 10 moves the guide 5 sufficiently far to bring the spring 9 to the opposite side of the pivot of the guide, whereupon the spring snaps the guide 5 into position against the guide 1 and splicing is resumed. At each subsequent revolution of the machine a second cam-piece 27 on the lever 22 is acted on by a cam 28 on a disc 29 to withdraw the guide 5 for about half a revolution, thereby causing the yarn to pass behind and be missed by the corresponding needles. The striping guides 1, 2 are moved into or out of action by springs 6, 7 and levers 11, 12 controlled by appropriate cams 13, 14 on the drums 23. The yarn moved out of action is drawn between a pair of spring-pressed gripping-plates 16, 17 and is cut by a pivoted blade 15 operated by the cams 13. 14 or by independent mechanism. Specifications 15008/00 and 171,483 are referred to. According to the Provisional Specification, two inclines on the stitch-cam may engage needle butts of varied length to facilitate changing or reinforcing yarns without constantly trapping and cutting them, and the free space between the needle beds may be increased by raising the cup or disc which forms the draw edge for the upper set of needles.

Abstract: 1365170 Intermetallic compounds GES FUER KERNFORSCHUNG mbH 18 April 1972 [30 March 1972] 17939/72 Heading C1A [Also in Divisions C7 and G6] Intermetallic compounds, especially those of lithium, calcium, strontium, or barium with rhodium, palladium, iridium or platinum, are produced by a method which comprises mixing at least one Group VIII metal with at least one compound of another metal, and treating the mixture in a stream of highly purified hydrogen at 800‹ C. or above. The highly purified hydrogen may be produced by diffusion through heated nickel capillaries, or in a hydrogen/ nitrogen mixture obtained from sodium-dried ammonia, or by passing commercial hydrogen through a platinum asbestos/titanium sponge at 650‹ C., over molecular sieves, and then through liquid sodium/potassium alloy. Particular examples illustrate the preparation of LiPt7 from Li2O and Pt powder, and of CaPt2 from CaF2 and Pt powder. Other compounds specified fall within the general formula AyBx, where B signifies the Group VIII metal, A the other metal, x is 2, 3, 4, 5 or 7, and y is 1, 2, 3, 5 or 7. These intermetallic compounds may subsequently be decomposed under vacuum at a higher temperature, the evaporated metals being obtained in high purity by cooling while the Group VIII metals are recirculated.
