Abstract: 1,150,020. Ingot strippers. ADAMSONALLIANCE CO. Ltd. 20 Nov., 1967 [24 Nov., 1966], No. 52643/66. Heading B3F. Ingot stripping apparatus comprises a ram 14 which is initially moved by an hydraulic motor-driven screw device to strip an ingot from a mould until the hydraulic motor stalls, whereupon hydraulic fluid is applied to a piston to apply a higher stripping force to the ram 14. The apparatus comprises a central shaft 4 driven by an hydraulic motor 7 and having a splined head 8 that rotates an axially movable internally and externally screw-threaded nut 11 to move a sleeve 12 which carries the ram 14. The internal thread of nut 11 moves axially a further sleeve 9, the top end of which carries a piston 25 movable in a cylinder 26. In operation tongs 22 grip the mould and the ram 14 is lowered on to an ingot until the hydraulic motor stalls, whereupon pressure fluid is diverted to the cylinder 26 and the piston 25 is moved downwards. If the ingot is still stuck in the mould, further rotation of the shaft raises the piston to the top of its stroke and another downward stroke can be performed. The apparatus can be used for pushing down an ingot or for pulling up an ingot. Extractor jaws 31 are used in this latter operation and they are closed on to the ingot by the retraction of a member 27 so that slides 30 move along guides 29 to pivot the jaws 31.

Abstract: 527,257. Postal franking machines. UNIVERSAL POSTAL FRANKERS, Ltd. April 5, 1939, No. 10632. Convention date, Oct. 12, 1938. [Class 100 (ii)]  In a postal franking machine provided with a printing-drum carrying, on an axis transverse to its axis of rotation, a number of printing-wheels, together with setting-mechanism for the printing-wheels and for counter operating-mechanism, the setting- mechanism comprises a shaftcorresponding to each printing- wheel and carrying two gear wheels, one of which acts on the printing-wheel and the other on a corresponding arcuate rack acting to set fingers in position to actuate the counter. The device comprises a drum 1 secured to a shaft 3 rotatable in one direction only from a crank 7 but normally locked against rotation by a spring- pressed pin 39 mounted in the drum and projecting into an aperture in the casing 4. The pin 39 is engaged by a lever 43 on a shaft 42 provided with a finger-lever 41. The drum carries printing-wheels 17 projecting through the surface of the drum and rotatable on a shaft 19 transverse to the shaft 3, the wheels 17 being provided with gear-wheels rotated from gear-wheels 21 to which are secured setting handles.23 projecting through apertures in the drum. The gear-wheels are carried by nested shafts 24 which also carry gear-wheels 26 meshing with arcuate racks 27 movable concentrically relatively to the drum. The racks carry radially-slidable pins 32 having projections engaging a cam-slot 35 in the racks 27. Movement of the racks therefore causes pins 32 corresponding in number to the figure on the printing- wheel 17, to project beyond the periphery of the drum to actuate the counter .38. When the pin 39 is actuated to release the drum, a pin 44 attached thereto acts to lock the printing-wheels and pins 32 against adjustment. Letters &c. to be franked are passed over a table 9 between the drum and a roller 10 carried by a pivoted lever, 11 under the control of an adjustable spring 13.

Title: Signal generating circuits

IPC: G06F9/308
Filed: 1965-12-16
Abstract: 1,129,659. Data processing machine. WESTERN ELECTRIC CO. 16 Dec., 1965 [30 Dec., 1964], No. 63380/65. Heading G4A. A digital electric data processing machine having a memory containing a series of stored programme instructions, contains an instruction defining a mask operation, an instruction decoder and means responsive to first decoded signals specifying the size of an adjacent bit mask window and to second decoded signals specifying the magnitude of shift of the window from a right adjusted position for controlling circuit masking means to provide a mask window of the size and at the position specified. An instruction such as Mi Qj would be used, M indicating that a mask is required and i being its width, Q indicating that the mask is displaced and j the shift required. The word is applied to a decoder (13, Fig. 1, not shown) which responds by generating a first multi-bit binary coded signal indicating the size of the window and a second representing the size of the shift. The decoded data is then added in adder 22 to produce i and j and the j number and the sums taken via gates to translators 32, 33. Normally gates 28, 29 are enabled. The translators produce a 1 out of m signal from a binary input i.e. only 1 lead is enabled, producing outputs B 0 -B m-1 , E 0 -E m-1 . The outputs are taken to a set of NAND gates 37-43 interconnected according to Boolean notation: for gates with cross coupling and for the first pair of gates. At the output of each translator the single lead carrying the 1 out of m code is in a lowvoltage condition and all other leads are high. The G gate outputs are applied to further gates 47-51, 47<SP>1</SP>-51<SP>1</SP> in the insertion mask circuit. If leads B 1  and E 2  are low voltage i.e. shift 1 left and a two bit mask, then B 0  and G 0  are high, gate 37 is high. E 0  and E 1  are high so gates 38, 39 are low. The low voltage from gate 39 holds B 2  low thus disabling gate 40. Eg is low so gates 41, 42 are disabled to produce high voltages on G 3  and G 4 . These disable gates 50, 51. The same high voltage carry is propagated to the gates of higher significance. Thus only gates 48, 49 are enabled to pass information in the two bit positions represented thereby. A transistor NAND gate is illustrated in Fig. 3 (not shown). A modification of circuit 36 of Fig. 2 is illustrated in Fig. 5 (not shown) the gating arrangement being different. Each B lead plus a carry goes to a first set of NAND gates. The output of the first set plus the E leads go to a second set of NAND gates and the output of these form leads G 0 -G m  and the carry. A complement mask may be produced by feeding the shift number to translator 32 and the sum to 33 via gates 30, 31. In a second embodiment instruction (Fig. 4, not shown) Ek Qj, j specified the beginning position of the mask and k the end position and a different decoder [32<SP>1</SP>] is used to produce the signals applied to the set of gates 36.

[Also in Divisions B8, F2 and G3] To guide an endless metal band 2 in a controlled path, a controlled temperature differential is maintained between the opposite edges of the band. This may be used to neutralize a tendency for the band to steer in one lateral direction, or to cause the band to steer or curve in a particular lateral direction. In Fig. 1 the band 2 is a moving electrical contact or a continuous slip sheet for a workpiece 10 in a continuous laminating press. The band is supported on rollers 8 journalled in plates 6. To sense a tendency for the band to track laterally, a rod 20 carries position washers 22 adjacent the band edges, the rod 20 actuating a microswitch 16 controlling a solenoid valve 14 for a pilotoperated gas burner 12. Either two such burners and control systems act one on each edge of the band, or the single burner is movable selectively to one or other edge. Thus any tendency to move laterally is automatically neutralized. In Fig. 5, a water spray tunnel 26 is included to keep the band temperature from exceeding an allowable maximum. Alternative methods of heating are a hot contact shoe, an electrically or gas heated plate, or a radiant heater. Heating may be at one or more zones, or round the entire band. A cooling device may be used instead of a heater, or one edge may be heated and the other cooled. The band may be a conveyer, or a band saw, in the latter case the control of temperature gradient being used to steer the band against a workpiece.
