Title: Digital control apparatus
IPC: G05B19/23
Filed: 1961-04-11
Abstract: 906,882. Electric selective signalling systems; numerical control systems. WESTINGHOUSE ELECTRIC CORPORATION. April 11, 1961 [May 16, 1960; May 20, 1960] Classes 38 (6) and 40 (1). In a machine-tool control system, a tape reader 22 enters a signal representing a desired position in one co-ordinate into a counter 24; a signal representing the actual position of the controlled machine member stored in counter 44 is entered into error counter 32 which is then supplied with signals representing the desired position and the output of counter 32 representing the difference between the actual and desired positions is used to move the controlled member to the desired position. Similar systems are used for the X and Y co-ordinates. In one embodiment described, counter 24 is a four-stage binary counter, and tape reader 22 enters a first binary coded signal representing the most significant digit of the desired position. Gate 28 is opened and pulses from oscillator 30 are supplied to counter 24 to reduce its count to zero, whereupon gate 28 is closed. The next digit is entered into counter 24, gate 36 opened to reduce the count to zero, and the operation is again repeated for the third digit using gate 38. The three trains of pulses representing the desired position are supplied to the respective stages of counter 32 where they are subtracted from the actual position signal stored therein. The difference output of error counter 32 is converted to analogue form at 54 and applied to the appropriate co-ordinate axis motor 40 which drives the machine element 20 and a pulse generator 42 which supplies pulses representative of the degree, and, if desired, direction of movement, to counters 44 and 32. Gates 48, 50, 52 are closed while the member is being moved, so that although counter 44 follows the change in position of the member, it does not further influence counter 32 until a new positioning operation is to be performed. The pulses from generator 42 supplied direct to counter 32 reduce the error count therein to zero whereupon motor 40 is stopped.

Title: Improved method for obtaining metallurgical coke from poorly-coking coals
IPC: C10B57/04
Filed: 1961-04-12
Abstract: Poorly-coking coals are carbonized to obtain metallurgical coke of high quality in a process which comprises drying ground coals at a temperature greater than 100 DEG  C. but below the pyrolysis temperature of the coal, adding a hydrocarbon binder in liquid or viscous state before or after drying the coals, changing the mixture thus obtained into a coke furnace, and coking in conventional manner, the already high charging density of the initial dry coal being artificially increased to obtain changing densities greater than those which can be obtained by conventional dry changing, and may be greater than those which are obtained by the conventional stamping method for these same wet coals, for example by stamping the hot mixture prior to changing, or briquetting of the hot mixture and stacking prior to changing into a bunker of the stamping bunker type, or by briquetting a portion of the dry mixture and gravity feeding together with dry fines. Anti-cracking agents, such as a mixture of ground coke breeze and semi-coke, may be added to the mixture.  The hydrocarbon binder may be coal tar pitch, artificial pitch obtained by hydrogenation, bitumen, residues or extracts from solvent extraction of pitch, bitumen, or resins, or extracts from coal, peptized coal, pitch, bitumen, or resin, or residue from the distillation often polymerized by an acid.

IPC: F41A19/33
Abstract: 131,931. Armes Automatiques Lewis Soc. Anon., and Norman, G. Sept. 25, 1917. Machine guns. - Consists in modifying the trigger-mechanism of a Lewis gun to obtain either single-shot or automatic fire by pivotally mounting on the trigger 1 a transmitter 3 which has a part 10 spring-pressed against a regulating stop 12 and a surface 6 in engagement with the end 7 of the sear-lever 8, the mechanism being contained within the usual pistol grip. The stop 12, which is rotatable by means of a lever 15, is shown in Fig. 1, adjusted to the position' for firing single shots. In this position, when the trigger is pulled, the end 7 of the sear-lever is at first raised, but afterwards slips past the surface 6 to enable the sear 8 to arrest the rod carrying the firing-pin after each shot. To adjust the mechanism for automatic fire, the stop 12 is rotated until a flat 16 engages the part 10 of the transmitter. In this 'position, the surface 6 and the end 7 of the searlever remain in engagement whilst the trigger is kept pulled, and hold the sear out of the path of the rod carrying the firing-pin.

Abstract: 484,358. Rotary furnaces. METALLGES. AKT.-GES. May 11, 1937, No. 13384. Convention date, .June 10, 1936. [Class 51 (ii)] A rotary furnace for metallurgical purposes is formed with an internal muffle which is held in position against abutment 3, fixed to the furnace shell by spring-pressed bricks 8. Bricks 3a shaped as shown may be interposed between the muffle and the abutment 3 to give a larger bearing-surface, and where the muffle is made in segments the bricks 3a, 8 are arranged to cover the joints. The bricks 8 have stems 8a sliding between spaced wedge blocks 4, 5 and pressure is applied by plungers 9 through heat-insulating blocks 11. In the case of long muffles built up of sets of segments arranged end to end, leakage of molten metal through the peripheral joints is minimized by flanging the segments and so notching the flanges, as at 13, that transfer of metal across a, peripheral joint will take place only where the muffle is supported by the bricks 3a, 8. The furnace is heated by gas supplied at the ends of the flue .spaces 18 and burnt with air admitted at distributed points 31. The heating-gases may be into the muftle through pipes 17. Molten metal is discharged into a channel 20, and slag through the pipe 21 into a container 26.
