Title: Improvements relating to apparatus for making products derived from molten metal
IPC: B22D11/00
Filed: 1938-08-22
Abstract: 521,690. Making rods and pipes. MERLE, J. M. Aug. 22, 1938, No. 24671. [Classes 83 (i), 83 (ii) and 83 (iv)] Building up articles by spraying ; casting-machines; casting composite articles ; cores.-Molten metal is formed into a thin film, on a moving surface cooled to below its solidifying point and caused to travel unsupported and form solid particles which are impacted to form a continuous product. The molten metal may be discharged onto a band 242 having thickened edges moved rapidly in the direction indicated by a drum 245 and cooled by water 246. The film thus formed and cooled is projected into a water-cooled mould 247, the product being withdrawn and, if desired, shaped &c. by rollers 252. In a modification the same metal, or two different metals, in receptacles 239<SP>1</SP>, Fig. 4, is discharged onto bands 242, 2421 and thus projected into a mould to form a compound bar 251<SP>1</SP>. In another modification metal is discharged into a channel formed by two broad driven bands 28, 29, Fig. 5, of steel or copper or an alloy thereof and two narrow spacing bands 30 at the edges of the broad bands. The bands 28, 29 are cooled by water sprays 43 and the projected film is impacted in a water-jacketed mould 36 of a contour to produce a rod, slab, rail, or angle or other section. If a tube or other hollow section is required a jacketed rotating core 106, Fig. 8, is arranged in the mould and the water 114 discharged from the jacket may engage the inside of the tube. The bands may be cooled by air, mercury &c. instead of water, and the rate of cooling the film may be varied by making the bands of a metal, alloy, or other substance having the desired conductivity. The process can be applied to high speed steel and to stainless irons or steels. The bodies produced are stated to be uniform in texture and free from surface chill and their properties to be substantially retained after working. Specifications 519,932, 519,933, and 521,689 are referred to.

Title: An improved receiver of electrical currents for the remote control of apparatus
IPC: H01H51/32
Filed: 1934-08-30
Abstract: 438,542. Electromagnetic relays. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, Seine, France. Aug. 30, 1934, No. 25030. Convention date, Sept. 14, 1933. [Class 38 (v)] [See also Group XXXVIII] In a system in which remote control is effected by currents superposed on power circuits, a relay responsive to the superposed currents steps a ratchet wheel at a predetermined rate when operated by currents of the signalling frequency and at a slower rate when operated by disturbing currents and a servomotor is provided which ensures operation of the remote equipment when the relay operates at its signalling rate but neutralizes the action of the relay when it steps at a slower rate. As shown, the relay 61, tuned to the signalling frequency, steps wheel 58 so that satellite 40 rotates in the direction of arrow 56 and cam 41 closes at 50, 51 the circuit of motor 32. The motor drives shaft 31 which is geared to pinion 38 so that pinion 38 turns at a slower rate than pinion 57 and the shaft 39 continues to rotate in the same direction. Cam 42 now becomes effective, moving arm 18 about pivot 19 so that spring 28 forces shaft 24 to the left and pinion 29 engages pinions 20, 30 so that shaft 7 rotates. Cam 8 moves off normal, closing a parallel circuit for motor 32 and holding arm 18. When the impulse ceases pinion 57 stops moving and pinion 38 drives satellite 40 with shaft 39 and cams 41, 42 back to normal. The motor stops when beak 14 enters the next notch in cam 8, opening the motor circuit and forcing arm 18 and shaft 24 back to normal. If the relay is operated by disturbing currents, the shaft 39 is rotated and cam 41 is effective to start motor 32, but as shaft 39 is now rotating at a slower rate, the pinion 38 rotates faster than pinion 57 and the shaft 39 is rotated back to normal before it has moved far enough for cam 42 to be effective and the selector shaft 7 to be coupled.

Title: Equalising device for the withdrawal of filaments from several spools rotatable independently of one another, more especially in double-twist twisting frames
IPC: D01H1/10
Filed: 1960-07-18
Abstract: 953, 699. Regulating yarn draw off. BARMER MASCHINENFABRIK A. G. July 18, 1960 [July 18, 1959; Nov. 17, 1959], No. 25048/60. Headings DID and D1J. A device for ensuring that the lengths of threads drawn from two or more spools are equal comprises a brake device which acts in all the spools simultaneously to prevent any spool leading or lagging. In Fig. 1 a double twist doubling device which has two independently rotatable spools 7, 8 mounted on a support 1 is provided with a protective cage 9 mounted on the support 1 and terminated at its upper end by a ring 10. A rod 11 rotatably mounted in the cage carries members 19, 20 biased by a spring 32 (the tension of which may be adjustable) to brake the spools. The yarns 26, 27 leaving the spools pass over rotatable rods 14, 15 (see Fig. 2) spaced about the periphery of the cage 9 and then through guides 16, 17 on the rod 11; the yarns then pass upwardly to meet and run over a common guide pulley 22 in the normal way. In Fig. 6 braking members 117, 118 are carried by a forked member rotatable at right angles to its supporting rod 111 (equivalent to rod 11 in Fig. 1) so that a difference in the diameter of the spools does not prevent even braking. The braking members 117,118 which are interchangeable may have roughened surfaces and the spools may each be provided with a braking surface of different roughness. The arms of the forked member on which the braking members are mounted may be separately adjustable to allow for a relatively large difference in diameters of the spools. Balls or rollers braked e.g. by magnetic means may alternatively be used as braking elements.

Abstract: 600,292. Filling bags. ENSOR, E. G. Sept. 27, 1945, No. 25127. [Class 94(i)] [Also in Group XVIII] Means for automatically filling bags with a measured content comprises an inclined delivery channel down which the material to be bagged may gravitate, automatically operable measuring means associated with the channel, a bag opening tray fitted at the lower end of the channel, a movable bag holder adapted to be advanced towards and retracted from the tray thereby causing the latter to enter and open a bag in readiness for filling, and means for actuating the bag holder and the measuring means. The material to be bagged is conveyed from a supply by an endless conveyer 20, Fig. 2, and deposited on an inclined apron 12 whence it passes to diverging inclined channels 9, Figs. 1 and 2, and to parallel inclined delivery channels 7, through a bag opening tray 53 and into a bag 52 contained in a bag holder 51, such delivery channel having this bagging apparatus. The channels 9 and 7 are joined by lap connections 8. The inclination of the channels 9 is adjustable by a hinge 22 and screw and slot mechanism at their upper ends. The bag holder 51 is carried on a pivoted arm 39 and is advanced towards and retracted from the tray 53 by a pedal 48 acting through a lever 45. As the holder is advanced, the element 53 enters and opens a bag in readiness for filling. The measuring means comprise gates 26, 27, 28, 29, which are operated from the pedal 48 and act to allow a measured quantity of material to pass through the element 53 into the bag (see Group XVIII).

Abstract: Diborane is prepared by reacting a metal borohydride with an alkyl ester of a fluoroboric acid.  Sodium and calcium borohydrides may be used and these may be prepared from the metal hydride and the alkyl ester of a fluoroboric acid.  Esters are of formula FnB(OR)3-n, where R is an alkyl group of up to 10 carbon atoms and n is 1 or 2, e.g. methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, tert-butyl, nonyl and decyl esters.  Reaction may be effected at 40-200 DEG  C. at atmospheric or hydrogen super-atmospheric pressures in an inert suspension or a solvent medium, e.g. tetrahydrofuran or a hydrocarbon.  In examples, an argon atmosphere is used.  The metal tetrafluoroborate, which is also produced in the reaction, may be converted to boron trifluoride or a fluoroboric acid alkyl ester for re-use.
