Title: A Process of and Apparatus for Teeming Molten Metal
IPC: B22D9/00
Filed: 1967-04-10
Abstract: 1,177,986. Casting processes. ARBED, ACIERIES REUNIES DE BURBACH-EICHDUDELANGE S.A. 10 April, 1967 [19 April, 1966], No. 16340/67. Heading B3F. Additives for the treatment of cast metal may be added to the pouring jet passing from a ladle to a mould via casting tube 7 by providing a pipe 5 Joining into the casting tube 7 and leading from a container 1 holding the additives. The container 1 may be pressurized by a neutral or reducing gas, e.g. argon or carbon monoxide, admitted to container 1 via T-connection 8 having inlet and release valves 9. The pipe 5 has a sealing Valve 3, aregulating valve 4, and is heat-insulated by a layer 6. With the casting-tube 7 positioned with its lower end near the bottom of the mould, the gas may act as a washing gas as it rises up through the molten metal by carrying inclusions up with it. The additives may be pushed along the pipe 5 by mechanical pressure means, e.g. a piston. The pouring tube may lead into an intermediate tundish which feeds one or a number of moulds through auxiliary pouring tubes.

Title: Improvements in or relating to cigarette making machinery
IPC: A24C5/34
Filed: 1933-06-07
Abstract: 420,755. Weighing-apparatus fitted to cigarette-making machines. RUAU, F. F., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. June 7, 1933, No. 16346. [Class 143] The rate at which tobacco is fed to a cigarette-making machine is regulated proportionately to the movement of the beam of a weighing device which receives at intervals batches of cigarettes from the machine. To the beam 1, Fig. 2, is attached an arm 2 having a number of small steps 6 on each side, and a plain or serrated upper edge 7. A camactuated lever 11 periodically lowers two feelers 5, fixed to bell-crank levers 8, on to the plate 2 after the beam is at rest. If the weight of the batch of cigarettes is normal both feelers are arrested by the edge 7, but otherwise one feeler is arrested by the edge 7 whilst the other comes into contact with one of the steps 6 and through an arm 81 on the lever 8 turns a carrier 23 about a pivot 20 to an amount dependent on the deflection of the beam. When the cam moves the rod 11 upwards the lever 8 moves the arm 81 away from the carrier 23, which is held in its inclined position by a pawl 124 that engages a rack 25, until a screw 26 on the rod 11 trips the pawl, and allows the carrier to fall, by gravity, back on to a stop 24. A pawl 32 which is mounted on a bell-crank lever 31 is constantly vibrated near a ratchet wheel 38 by a lever 34 driven through an eccentric 37, and movement of the carrier 23 away from the stop closes a mercury switch 18 to energize a solenoid 27, Fig. 5, and cause the armature 29 to move the pawl into engagement with the ratchet wheel 38 and rotate a shaft 40 in a direction determined by the particular feeler that makes contact with the steps 6, to alter the speed of the tobacco feeding mechanism. This continues, until the circuit is broken by the screw 26 tripping the pawl 124, for a time dependent on the height of the pawl 124 which depends on the inclination of the beam. In a modified construction the feelers 150, Fig. 8, are carried by arms 44 which are rotatably mounted on a spindle 45; by engagement with stops 46 they tilt switch carriers 123 that act through a pawl 48 or 49 to turn a ratchet wheel 47 counterclockwise. The feelers are actuated by a rod 111 provided with a slot 53 with which co-operates a pin 52 carrying a pawl 50. As the rod 111 moves upwardly the pin 52 is engaged by the bottom of the slot 53 and rotates the wheel 47 and the carrier 123 clockwise, the weight of the carrier holding the pawl 48 or 49 in engagement with the wheel 47. The carrier 123 is released and falls by gravity into its normal position, breaking the mercury switch when the pawl 48 or 49 is disengaged from the wheel 47 by a fixed trip stop 59. The length of time the circuit is closed and the shaft 40 rotated depends upon the angular movement of the carrier 123 about the spindle 45 and this is determined by the extent of movement of the feelers 150. Specification 375,463 is referred to.

The bits of k input channels, k being an integral multiple of N, are fed in parallel at the rate of one bit per input channel to form parallel words of kN bits which, in a multiplexer 81, are multiplexed into k parallel words of N bits. These parallel words of N bits are converted in a transcoder 82, 83, into parallel words of N' digits which are applied to the channel 6 by way of a parallel/series converter 84 and a shaping and timing circuit 5'. At the receiver (Fig. 3B, not shown) a similar de-multiplexing operation recovers the data on individual output channels. As described with reference to Figs. 3A and 3B, the three level codes 4B3T or MS43 are used for transmission on channel 6, so that N = 4 and N<SP>1</SP> = 3, whilst k=4.

Filed: 1943-10-14
Abstract: In making balls, bullets, tool tips, or other articles from powdered metals, these are placed in a mould which is then vibrated without any rotation, to produce a compact mass for sintering.  The powder, e.g. carbides of metals such as tungsten, titanium, tantalum &c. mixed with a binder, such as cobalt, may be moistened with water, alcohol &c. and covered with a plug of graphite, metal &c. to prevent loss of powder.  The vibration may be effected by placing the mould on a rubber-cushioned steel block arranged in a solenoid connected to an alternating current supply. The consolidated powder may then be heated to a low temperature to sinter it partially, prior to removal for complete sintering at a high temperature or this may be applied at once.  In the first case a steel mould may be used, otherwise it is made of graphite, alumina, or other carbonaceous or ceramic material.  Centrifugal force may be applied to the mould before or after vibrating.

Abstract: 1424226 Agricultural track marker; tractor hitches AMAZONEN-WERKE H DREYER 10 April 1973 [11 April 1972] 17084/73 Heading A1B, A1D and A1P A control device for lifting and lowering 'track markers is characterised in that movement of the markers results from vertical movement of an implement carried by tractor lifting arms and provides automatic alternation between two track markers carried one on each side of the implement. When an implement 16 is lifted by rotating tractor lifting arms 7, 8 anticlockwise, lever 9 rotates with arm 7 about a pivot 10 causing an anticlockwise force on a lever 1 via a spring 15, a plate 13 and an arm 11. This causes a pulley 12 on the end of the lever 1 to move in the direction of the arrow 27 (Fig. 3). A wire 20 passing over pulleys 12 and 19 terminates at pulley blocks 2 and 2' and since pulley block 2' is locked against a stop 26' by a pawl 24', movement of the pulley 12 results in inward movement of the pulley block 2 and also a wire 18 attached to a left hand track marker (not shown). Towards the end of its movement the pulley block 2 makes contact with the end of a swinging arm 23 (Fig. 2) and displaces an assembly 3, including a rod 21. When the pulley block 2 has reached the end of its stroke, a rod 21 has caused rotation of the pawl 24', thus unlocking the pulley block 2', and also allowed the pawl 24 to rotate clockwise with gravity to lock the pulley block 2 against the stop 26. Also the end of a spring 25 attached to the swinging arm 23 has toggled about a pivot 22 causing the arm 23 to rotate clockwise to its second stable position. Lowering of the tractor lifting arms will now cause movement of the pulley 12 in the direction opposite to the arrow 27 and thus outward movement of the pulley block 2' and downward movement of the right hand track marker attached to the wire 18'. Subsequent movement will cause the left and right hand track markers to lift alternately. Movement of each marker through a limited stroke can be made without reversal taking place.
