IPC: B22D27/04
Filed: 1957-09-17
Abstract: <PICT:0870212/III/1> <PICT:0870212/III/2> <PICT:0870212/III/3> <PICT:0870212/III/4> Grain-oriented ingots of metal are cast in a mould 22 (Fig. 3) having at the bottom a seed body comprising laminated strip 10 and 101 of polycrystalline body-centred cubic, oriented, rolled sheet metal, the majority of the grains of each strip having their crystal lattices oriented so that a pair of parallel, oposite cube faces 11 and 14 (Fig. 1) are perpendicular to the rolling direction and to the plane of the sheet, and the remaining cube faces are inclined at an angle of 45 degrees the plane of the sheet, the strip 10 being arranged in the mould 22 at an angle of 45 degrees to the bottom of the mould and with the edge of each strip which forms a surface presented to the mould cavity being parallel to the rolling direction of the strip.  Strips 101 are wider than strip 10.  Molten metal of the same composition as the strip, is poured into the mould, melting the top edges of the strip, and the bottom of the mould is cooled by passing a coolant through a heat exchanger 30, so that an ingot grows on the seed body having unit cube faces of the space lattices parallel to and perpendicular to the mould walls.  The ingot may then be rolled to form sheet metal having the cube faces parallel to and perpendicular to the surface.  In another embodiment strips 40 (Fig. 4) are cut having their shortest surface dimension parallel to the rolling direction, and a seed body is formed by arranging the strip face-to-face with their faces, extending vertically, their longest dimensions extending horizontally, and with their faces at 45 degrees to the walls of the mould 45 (see Fig. 5).  An ingot is grown as before.  The metal may be iron containing up to 5% of silicon or molybdenum, or up to 8% aluminium. Specification 870,209 is referred to.

Title: Reaction products of chlorourea and tertiary phosphite esters
IPC: C07F9/24
Filed: 1966-06-29
Abstract: 1,157,316. Dialkyl ureidophosphonates and thiophosphonates. ARMOUR AGRICULTURAL CHEMICAL CO. 29 June, 1966 [2 July, 1965], No. 29263/66. Heading C2C. Dialkyl ureidophosphonates and dialkyl ureidothiophosphonates are obtained by reacting chlorourea and a trialkyl phosphite or a trialkyl mono-, di-, or tri-phosphite ester in an aprotic solvent, cooling the reagents during reaction and recovering the resulting product. The products are of the formulµ wherein R is alkyl, and the invention includes as new products (a) dialkyl ureidophosphonates including the dimethyl, diethyl and di-nbutyl esters and (b) dialkyl ureidothiophosphonates including diethyl ureido mono-, di-, and tri-thiophosphonates. The reaction is preferably carried out at between 0 and 20 C. and suitable aprotic solvents include acetonitrile, tetrahydrofuran and dioxane. The chlorourea can be used directly or can be prepared in situ, e.g. by chlorination in acetonitrile of a urea slurry, preferably at between - 5 and 0 C. Excess urea may be used in the latter reaction, the unreacted urea serving as a buffer to improve the stability of the chlorourea-acetonitrile system. The sodium salts of the products can be formed by reacting them with sodium or sodium amide in liquid ammonia. Triphenyl phosphine reacts with chlorourea to form a stable phosphonium salt: (C 6 H 5 )P<SP>+</SP>-NH.CONH 2 Cl-, which hydrolyses readily in water to form triphenyl phosphine oxide and urea. The phosphonium salt also reacts with butyl lithium or sodium alkoxide to form the corresponding phosphinimine derivative (C 6 H 5 ) 3 P = N-CONH 2 .

Title: Improvements in or relating to coin-operated machines
IPC: G07F5/10
Filed: 1924-12-08
Abstract: 245,571. Holcroft, C. W. Dec. 8, 1924. Testing coins; coin action; electric-connection; delivery of articles stored in piles. - In a coinfreed machine the coin, directed by a shoot to a pair of contacts, bridges them to cause automatic electrical mechanism to operate, means being provided whereby a coin of larger than the proper diameter is arrested before reaching the contacts and returned. The invention is shown applied to a machine having a delivery drawer for articles stored in a pile. A coin, inserted through a gauging slot 15, Fig. 1, in a plate 14, falls down a shoot 17 to bridge contacts 30, 31 thereby completing the circuit of an electromagnet 27 which attracts spring-controlled armature 22 having a pin 27 normally engaging a slot in a block 25 carried by a drawer 12. The drawer can now be pulled, the block 25 pushing out the lowest article from a vertical pile. There may be more than one slot in the block 25 to ensure that the pin 21 always moves into locking engagement when the drawer is returned. A third contact 44 co-operating with the contact 30 arrests a coin of larger than the proper diameter. Coin-discharging mechanism; returning coin.- A coin bridging the contacts 30, 31 is maintained upright by a hinged extension 33 of the shoot 17 which is pressed against a stop 35 by a spring 34. A plate 36 having a curved extension 37 through an aperture in which a projection 40 on the extension 33 passes, is also hinged to the shoot 17. A cam 41 on a rod 42 attached to the drawer acts on the extension 37 and projection 40, when the drawer is pulled out, first to bring a ledge 38 on the plate 36 under the coin to support it, then to swing the plate 36 and extension 33 over a hopper 43 thereby moving the coin away from the contacts in a direction normal to its faces, and finally to move the extension 33 alone to carry the coin off the ledge 38 and allow it to drop into the hopper, Fig. 6. A large coin arrested between the contacts 30, 44 completes the circuit of an electro-magnet 45 which attracts its armature 46 and moves a lever 47 to swing, by engagement with a projection 48, the shoot extension 33 over a return shoot 32 without moving the plate 36. A cut-away portion of the contact 44 allows the improper coin to drop. A small coin is not arrested by the contacts and drops straight through to the return shoot. Manual means for removing the improper coin may be provided, and comprises a rod 51 having a member 53 to actuate the lever 47. The other end of the rod reaches outside the machine where it is covered by a plate 52 provided with a lock to prevent unauthorised use. Also the coin may act by weight on a member such as 47. Coin-slit closing-devices.-A rod 19 controlled by the pile of articles closes the coin slit 15 when the articles hopper is empty.

Filed: 1945-11-06
Abstract: 611,059. Winding yarns. BRUGGER, A. Nov. 6, 1945, No. 29514. [Class 120(ii)] In a thread-guide traverse mechanism for thread-winding machines in which an exchangeable transmission gear and a worm gear are interposed between the winder spindle, and the traverse control cam, the transmission gear and the worm wheel are pivoted on vertical axle pins so that the transmission gear may be removed upwardly during exchange. As shown, the driving pulley 4 of a cop winder is secured to a clutch member 3 journalled on winder spindle 2. A clutch member 5, feathered to spindle 2, is brought into and out of engagement with member 3 by movement of a finger 7 secured to a control shaft 8. Traverse control cam 18 is driven from shaft 2 via worm 9, worm wheel 10, and pinions 13, 14 which may be changed to alter the speed of traverse. Pinion 13 is mounted, together with worm wheel 10, on a fixed vertical axle pin 11, and engages the worm wheel by a snug 12. Pinion 14 similarly engages the hub 17 of cam 18 which, together with pinion 14, is mounted on a fixed axle pin 15. Cam 18 engages, by a circumferential groove, a bell crank lever 19 pivoted at 20, transmitting reciprocating motion to the thread-guide rod 22 via link 21 which may be set in one of a number of notches in lever 19 to vary the throw of rod 22. In another embodiment, two pairs of change pinions are used, and the worm wheel 10 is mounted on pin 11. As shown, the worm gearing is disposed, in the transmission of drive to the traverse cam, ahead of the change gearing; these positions of the worm and change gearing may alternatively be exchanged.

Title: Improvements in or relating to method of and apparatus for abrading
IPC: B24B33/06
Filed: 1939-11-07
Abstract: 536,261. Abrading-machines. MICROMATIC HONE CORPORATION. Nov. 7, 1939, No. 29570. Convention date, Nov. 18, 1938. [Class 60] Round holes enlarging and trueing.-A machine having a hone 11 or other abrading element is arranged to apply a light pressure between the hone and work at first, to prevent rapid wear of the stones, and then increase this pressure. If desired the pressure may be reduced again towards the end of the operation to produce a smoother finish. A hone or a number of hones 11 is carried by a head 12 by which the hones are introduced into the work. Each hone can be expanded by cones operated by a piston in the head 12, the operating fluid being controlled by a reversing valve 14 operated by a solenoid 15 and time switch 66 or a revolution counter &c. The fluid is supplied by a pump 17 and its pressure is regulated by an adjustable relief valve 21 to produce the desired maximum pressure by the hone. Any desired lower starting and finishing pressures are obtained by other relief valves 23, 27 which are connected to the pipe 18 at and for the times desired by valves 26, 29, solenoids, and time switches 67, 68 &c. In a modification the valve 14 is supplied with fluid under a gradually increasing and then a gradually decreasing pressure by a relief valve 33, Fig. 8, connected to a piston 79 with a passage 81 connecting its two faces. The chamber A, below this piston, is connected by a passage 78 to the fluid supplied by the pump to the valve 14 and that B, above it, is a two-way valve 75, Fig. 6, which connects it alternately to two bleed valves 84, 85 which are adjusted to give a greater and smaller flow respectively than the passage 81. The chamber 34 is connected to the fluid supply pipe 18 and, by a pipe 74, to the valve 14 and the chamber C to exhaust. When the cycle of operations is commenced the valve 85 is in use and the pressure on the valve 33 is at first equal to that of the spring 32 less that due to the fluid pressure on the lower face of the piston 79 which is the same as that in the pipe 18. Owing to the flow through 85 being less than that through 81 pressure on the upper face of the piston 79 increases and thus the pressure in the supply pipe 18 also increases to a maximum determined by the main relief valve 21. When the valve 75 is reversed by a time switch &c., the pressure on the upper face of the piston and in the pipe 18 falls gradually. Finally the time switch 66 opens the circuit to the valve 14 to retract the abrading elements.

Title: Thermostatic control of electric heaters
Inventor: EVANS THOMAS EDWARD
IPC: G05D23/24
Filed: 1957-09-20
Abstract: 858,949. Automatic temperature-control systems. NAPIER & SON Ltd., D. Sept. 17, 1958 [Sept. 20,1957], No. 29699/57. Class 38 (4). In a temperature-control system, heating elements having differing temperature coefficients form two arms of a bridge controlling a switch connecting a supply to the elements and a time delay device maintains the switch open for a predetermined minimum time after each interruption. As shown, heating elements 12, 13 form adjacent arms of a bridge, the remaining arms being equal value resistors 19, 20. The out-of-balance bridge voltage is stepped-up by a transformer 23 and rectified. The resultant D.C. signal is applied to the baseemitter circuit of a transistor 27 through resistors 36, 39. At a signal amplitude, set by the resistor 36, the transistor conducts to energize a relay coil 28 actuating change-over contacts 29-32. A contactor 11, energized through the contact 29, breaks a mains supply 10 to the heating elements. A capacitor 35 ensures that the coil 28 remains energized until completion of the change-over. A resistancecapacity circuit 37, 38 through contact 31 maintains the contactor in the " heat-off " position for approximately 10 seconds. A resistor 15 across the contacts of the contactor 11 passes a current through the heating elements so that for very high temperatures the circuit through contact 29 maintains the contactor 11 open until the heating elements cool. A capacitor 43 may be used to slug the contactor 11. A neon indicator 18 is lit through resistance-capacity circuit 14, 16 when the " heat-off " is longer than normal. In a three-phase system, the bridge is replaced by a star network with at least one arm of zero-temperature-coefficient material, the transformer 23 being connected between the star points of supply and heating element networks. For a direct-current supply, the bridge output is directly coupled to the transistorized relay.

Title: Improvements in and relating to the manufacture of hollow drill steel or other hollow bars
IPC: B23P11/00

Abstract: 425,134. Making lined hollow drill steel or other hollow bars. BEDFORD, R. A., Grange Farm, Stumperlowe, Sheffield. Oct. 26, 1933, No. 29759. Convention date, May 17. [Classes 83 (ii) and 83 (iv)] Destructible cores; working at specified temperatures; forging-dies.-In making hollow drill steel or other hollow bars by reducing a preformed hollow billet with an inserted tubular metal liner on a core which is subsequently removed, end pressure is applied to the liner after insertion in the billet in order to expand it outwardly against the wall of the hole so as to obtain a tight fit. The wall of the liner is supported interiorly during this process. The expansion may be effected by a hydraulically or otherwise operated flanged mandrel, punch, drift, or ram engaging one end and an abutment such as a faceplate at the other end, or by a pair of flanged tools inserted at opposite ends. The core may be inserted after the insertion of the liner in the billet either before or after expanding, or the core may be inserted in the liner and the liner and core then introduced together into the blank. If the core is inserted before expansion it supports the walls during that operation. The liner may extend beyond the ends of the blank in which it is inserted as a close sliding fit. A blank with its expanded liner may be heated in a furnace to from 900 to 1100‹ C. and a cold core inserted while the blank is hot or after it has cooled. In the former case the core is allowed to attain the temperature of the blank before reduction so as to become a tight fit in the liner. After the ends of the blank have been sealed by welding, plugging, &c., it is reduced by rolling &c., the liner being a tight fit in the bar without welding. The core is removed by fracturing or cutting off the ends of the bar to expose the core, subjecting this to tension to reduce the core and then extracting. The core may be weakened by nicking, prior to insertion, so that it may be extracted from opposite ends, the nick being filled up to preserve the contour. The core, which may be coated with lubricant such as graphite, may consist of a ductile metal or alloy having a higher coefficient of expansion than the blank, such as copper, copper alloy, or austenitic steel, and the liner may consist of stainless or rustless steel or other metal or alloy. The hollow billet may be formed by casting and then machining the hole or by boring a solid billet.
