Title: Improvements in or relating to refractory carbides
IPC: C01B31/30
Filed: 1963-06-10
Abstract: Spheroidal metal carbides, containing at least as much excess carbon as will go into solid solution with the carbide at temperatures above 1900 DEG  C., are prepared by heating pellets containing the metal or compound thereof, and sufficient carbon to react and provide the excess, to above the m.pt. of the carbide to melt and spheroidize the pellets.  Preferably the pellets are isolated from each other during melting by mixing with graphite powder, or by heating in a graphite bed.  A thin coating of graphite may thus be formed, and the spheroids may further be coated with pyrolytic carbon. Examples relate to nuclear fuel carbides (e.g. U, Th or U-Th, from the oxides) and poison carbides (e.g. Gd, Eu).  Reference is also made to U-Bl, U-Mo, U-Tr, and U-Nb carbides.

Title: Improvements in inking ribbon mechanisms for typewriting machines
IPC: B41J33/518
Filed: 1932-08-19
Abstract: 386,590. Ink-ribbon mechanism. SMITH & CORONA TYPEWRITERS, Inc., L. C., 51, Madison Avenue, Manhattan, New York, U.S.A. Aug. 19, 1932, No. 23301. Convention date, Jan. 15. [Class 100 (iv).] In typewriters in which the universal bar actuates the ribbon feed and ribbon vibrator, a shaft is rotated from the universal bar by a pawl-and-ratchet device which is shifted axially to slide the shaft in its bearings to gear it alternately with one or other of the spoolshafts. A pawl-carrier 21, Figs. 1, 3, and 6, is pivoted on the shaft 16 and straddles a ratchet-wheel 19 and cam boss 20 which are fast to the shaft. A bail-shaped pawl 22 is pivoted to the carrier at 23 and engages the ratchetwheel. A springy member 25, fast to the frame 10, prevents reverse movement of the ratchet-wheel. The carrier is rocked by the universal bar 28 through members 35, 36, a rock-shaft 37, and members 39, 40. The carrier may be shifted longitudinally, thereby sliding the shaft 16 to engage one or other of the bevel gears 15, by means of a finger-lever 41, acting on a lever 43 pivoted to the frame and engaging the vertical walls of the pawl carrier. A snap-detent 45 engages and holds the boss 20 in either position. Camming- levers 53 are pivoted to the frame at 55 and actuated by levers 49 adapted to be engaged by abutments on the ribbon 12, to effect an automatic reversal of the feed. The inwardly directed arms of the cam levers 53 engage one or other of inclined edges 57 on the carrier 21 so that when the carrier is tilted forward during the feed movement it is slid sideways. The levers 53 are normally held in inactive position by springs 52 connected to the levers 49 and are drawn towards each other by a spring 56, so that when one or other of the levers 49 is tilted the corresponding lever 53 comes into camming position. The ribbon vibrator is actuated by a lever 61, pivoted to the frame at 64 and bearing a dependent arm with two opposed pins 63. Either or both of the pins are engaged by slots 66 giving different throws in an upwardly directed arm of a yoke 65, freely mounted on the rock-shaft 37 and slidable along it by the action of a finger-lever 67 and links and levers 78, 70, 72. The rocking of shaft 37 is caused to actuate the yoke 65 by means of an arm 75, fast to the shaft and extending laterally through an aperture 76 in the yoke and engaging the edge of the aperture. When the lever 67 is in the medial or stencil-cutting position, both pins 63 are engaged by the yoke but the yoke is not actuated since the edge of the aperture 76 is opposite a notch 77 in the arm 75.

Abstract: 517,829. Indicating change of pressure in gas mains. METERS, Ltd., WHATMORE, A., and BARNES, H. V. Aug. 8, 1938, No. 23334. [Class 54] [Also in Group XXXVII] A device for indicating fall of pressure in gas mains which may be intentionally reduced when air raids are imminent comprises a diaphragm c subject to the gas pressure on its lower side and to atmospheric pressure on its upper side and biased by an adjustable weight g. When the gas pressure falls, the weight g descends and pushes down a tiltable rod k so that this engages an insulated contact spring m and closes the circuit to an alarm q. To stop the alarm ringing, a knob s is pulled and the end k of the rod slips from beneath the weight g and engages its cylindrical side. The weight is now clear of the spring m and the alarm circuit is open. When the gas pressure again becomes normal, the weight rises and the rod k slips into its original position ready to be again actuated.

Abstract: 735,270. Grinding and polishing knife blades. WURTTEMBERGISCHE METALLWARENFABRIK. Aug. 25, 1953 [Aug. 26, 1952], No. 23455/53. Addition to 678,058. Class 60. The device of the parent Specification, in which work-pieces to be ground or polished are brought into contact with a ring of granular or pasty abrasive material formed by centrifugal force in a tray rotating on a vertical axis, is provided with a holder for knife blades to be treated, the holder having means so to hold the tang 7 that the blade is deformed into contact with the concave surface 4 of an abutment 1. This means consists of a roller 10 secured eccentrically to a bolt 9 and provided with a transversely knurled circumferential groove 13. Rotation of the roller 10 by means of the bolt head 12 clamps the tang 7 against an abutment member 14, which may be provided with a groove 16, and draws the head 6 of the blade into contact with the front of the member 14 and a wall portion 21 of the holder. Thus clamped, the blade tends to lie on an axis 18, but is deformed by the surface 4 so that it is firmly held. The holder may be rotatably secured to a swingable arm by means of a bore 3 and is provided with hard metal armouring 15 to prevent excessive wear by the abrasive material. A recess 19 facilitates insertion of the tang 7.
Patent GB-801454-A (GB)
Title: Improvements in mechanism for forming a single row of cans into several rows
IPC: B65G47/71
Filed: 1956-07-30
Abstract: 801,454. Conveyers. EMHART MANUFACTURING CO. July 30, 1956 (Sept. 15, 1955], No. 23511/56. Class 78 (1). Means for forming a single row of cans into several rows comprises a rotary wheel having a series of open pockets in its periphery, each of which holds one can, means to feed successive cans from a single supply line into the pockets, means for retaining a can in its pocket which can be put out of action temporarily to permit entry of a can at the loading point and discharge of a can at a lower point, the retaining means for consecutive pockets being arranged to be withdrawn to permit discharge of the cans at angularly different locations around the axis of the wheel. The wheel 10, Fig. 1, comprises a pair of discs 10a, 10b, Fig. 2, connected in spaced-apart parallel relation and freely rotatable about a fixed shaft 11. A series of pairs of aligned pins 20 project towards each other from the inner faces of the discs, the distance between their ends being less than the length of a can 13. Adjacent pairs of pins form open pockets into which the cans pass as they roll off the end 12a of the feeding shoot 12. The disc 10a has apertures 26 formed in it, one for each pocket of a set 22 ... 25, through each of which a pin 27 can be projected to force a can against the disc 10b and thus retain it in the pocket. Each pin is mounted in the free end of a bar 28 which is pivoted at 29 to a bracket 30 on the disc 10a. A spring 31 urges each bar towards the disc, but retraction to permit entry of a can occurs when a cam follower 34 mounted on a bar 32a ... 32d carried by bar 28 runs on to a fixed cam 35. The place of entry of a can into the wheel is so arranged that the entry of a can into a pocket assists the rotation of the wheel. The bars 28 are of different' lengths and co-operate with cams 38 ... 41 disposed at different radial distances from the centre of the wheel to cause retraction of the pins 20 to allow successive cans to be discharged into channels 15 ... 18. Each of the sets 22 ... 25 is separated from the adjacent sets by a space 21 which also receives a can. The cans are retained in these spaces by a guard rail 43 which ends at the entrance to the channel 14. The rotation of the wheel is controlled by a motor-driven friction wheel which bears on the outer face of the disc 10b, or by the brake mechanism, 48 or governor 49 shown in Fig. 5. The brake consists of a pivoted arm 50 carrying a brake shoe 55 which enters a peripheral V- groove 53 in a wheel 54 secured to the wheel 10. The free end of the arm 50 is adjustably connected to one end of a spring 57, the other end of which is connected to the core 58 of a solenoid 59. The governor is driven by a wheel 62 bearing on the disc 10b and consists of a spindle 65 carrying vanes 68 which are immersed in a viscous fluid 67. In a modification intended for use with cans in upright position on an endless belt conveyer, a disc similar to the disc 10a, Fig. 1, is mounted to rotate in a horizontal plane above the conveyer.
