Title: An arrangement for the numerical control of machines
IPC: G05B19/29
Filed: 1962-03-22
Abstract: 995, 648. Programmed control of position. LICENTIA PATENT-VERWALTUNGS G.m.b.H. March 22, 1962 [March 22,1961(2)], No. 11022/62. Heading G3N. In a numerical control system comprising a closed-loop position system responsive to the comparison between an actual position value and a desired position value related to a data zero point, a store is provided in which at the beginning of a control operation a basic desired position value is stored, derived from an absolute zero point of the machine and the data zero point, which is combined with the desired position value of the data zero point before this desired value is fed to the control system. As shown, a work piece W<SP>1</SP> is mounted on a table T the dposition of which relative to the corner N a  of a bed is determined by scales L x , L y , having digital markings 1-20, which are scanned by photo-electric devices N x , N y . Initially scribed axes, intersecting at a point N r , are positioned beneath the tool and the position Y o , X 0  of this point is stored in memory devices Y o S, X o S. The positions of holes to be drilled in the work piece are recorded on a paper strip which runs through a reader L and series-parallel to parallel-parallel converter SP/PP to produce digital values X z , Y z  representative of the desired co-ordinate displacement of the relative to zero-point N r  relative to the bed and values Vy z , V xz  indicative of the sign of this digital values. The values are fed to a co-ordinate switching device KV comprising a plurality of and-gates &1- &10 and or-circuits v 1 -v 3  whereby the values are sequentially selected and presented, together with the stored co-ordinates of the relative zeropointer Nr, to a sum and difference unit SD. The addition or subtraction is determined by the instruction from logic circuit v3 which has a width of 1 lit. The resultant signal is fed to a comparison member wherein it is compared with the output X m , Y m  of a logic circuit A responsive to the outputs of the photo-electric devices N k , N v . The and-gates and logic-circuit A are simultaneously gated for the X and Y co-ordinates by clock pulses t x , t y . and the error signals from the comparison figures are fed to stores S x , S y  gated by clock pulses t xw , t yw , which through digital to analogue converters DA x , DA y  control servomotors M x , M y  positioning the table. When the stores S x , Sy are omitted the analogue error signals are switched to the appropriate servo-motor by a change-over device U. Manual control is effected by signals X p , Y p  V yp , V xp  and the appropriate and-gates are simultaneously fed by a hand synchronizing pulse.

Title: Improvements in paper cutters
IPC: B26D7/02
Filed: 1943-07-10
Abstract: 566,808. Guillotine cutting-machines. BELLAR, O. July 10, 1943, No. 11216. [Class 31 (i)] In a guillotine paper-cutting machine in which the stock is mounted on a bed supported on a frame 28, 30, 32, which is designed to be of narrow width to permit the passage of the machine through a workshop door, the cutting is effected by a reciprocating knife blade 23 mounted in a carrier 180, the stock being held during cutting by a vertically reciprocating clamp 25 which is reciprocated by the same cranks 166 and connecting rods 168 as actuate the knife carrier. The clamps are driven by a friction drive which yields at a given pressure and permits the blade to move relatively to the clamps which grip the stock with increased pressure as the cutter comes into action. As shown in Fig. 16 in the raised position of the cutter block 180, the low left edge of the knife 23 is below the level of the right edge, but in the descent of the block 180 the right end is caused to travel faster so that at the completion of the stroke the edge 23 is level, and the cutter is given a movement to the left as it descends, as well as a slight pivotal movement. These effects are produced by transmitting the reciprocating movement by blocks engaging level slots 176 and inclined slots 178, and by a fixed guide 186 engaging a pivoted block 184 on the knife block 180. The machine is driven by a fly-wheel 40, Fig. 1, driven by a belt 22, and the drive is transmitted to the crank-shaft 42 by mechanism involving a one-revolution clutch and also an overload device which yields and throws out the drive if the power is not adequate to complete the cutting operation. As a safety measure the clutch can only be thrown in by both hands of the operator, who operates a shaft 104 to cause a sliding cam 118 to expand arms 96, 98 which force into engagement with a drum 64, Fig. 5, on a gear 50 geared to the fly-wheel, spring arms 66 on a ring 68 connected to the shaft 58 of a pinion 60 which drives an internal gear 62 on the crank-shaft 42. Between the ring 68 and shaft 58 is a. connection comprising a cam member 76 which acts as an overload device and yields under great pressure, and so disconnects the drive of the shaft 58, which normally takes place by engagement of the cam 76 with a recess 74 in a disc 72 on shaft 58, as shown in Fig. 5. Before the shaft 104 can be operated to throw in the clutch, a lever 122 must be moved to permit movement of a rod 126 which is moved to the left by operation of the shaft 104. The clutch is thrown out automatically by a cam 138, Fig. 6 (not shown), which operates a roller on a rod 134 connected to the shaft 104. A brake band 142 is also applied and is controlled by spring pressure when the safety rod 126 returns. The rod 126 may also actuate a safety stop 162 which checks the wheel 62 positively by engaging a projection on the wheel if the brake fails.

Abstract: 1429927 Continuous casting; making electrodes T W GARLICK 7 March 1973 [10 March 1972 30 March 1972] 11334/72 and 15104/72 Headings B3A and B3F [Also in Division C7] A metal strip 41, Fig. 7, is continuously cast in a mould formed by a moving belt 32 and two moving edge dams 42, the dams each having a recess 53 and/or a projection 70, 71, Fig. 12, to produce complementary projections and/or recesses on the strip edge. There is also an upper belt 31 and the belts 31, 32 may be cooled and each be a series of water-cooled blocks interconnected by elements in a chain. The cast strip 41 is severed by a shear 44, Fig. 7, as at 60A, Fig. 6, so that the cut lengths, possibly provided with holes after casting, can be used as anodes (10), (10A), (10B), Fig. 1 (not shown), for use in a refining plant. The edge projections (11) recesses (15) and holes (14) provide means by which the anodes can be supported or can accommodate lifting devices. The spacing of the edge dams 42 is adjusted according to the strip width required. They consist of blocks 50 of steel or titanium or of replaceable face pieces 52, Fig. 11, of such metal on blocks of copper or light metal alloy. The blocks are strung, and secured by screw or rivet, on a continuous flexible metal strip 51, Figs. 11, 12. Lengths of stranded cable 81, Figs. 11, 12, passed through holes 82 through the blocks 50, and anchored by screws 83, 84, keep the latter together. To maintain a cable tension, it may be in two parts joined by a spring. To accommodate contraction of the cast strip, some edge dam blocks may be in two parts biased apart by springs, Figs. 16, 17 (not shown). As shown in Fig. 7, the edge dams 42 each pass through a guide 57 (and in Fig. 11) in a downsloping path to part from the cast strip which proceeds horizontally on a roller with a water-cooled shaft. The guides may have a series of small rollers instead of the lower and upper slide members 62, 63 indicated. The dams 42 are longer than the belt 32 and pass back to the casting region on a further guide 88. In a modification, Fig. 18 (not shown), the dams pass up around the top belt 31 and the cast strip slopes down gradually from the casting region. Recesses 85, Fig. 12, in the outer top edges of the dam blocks 50 mesh with wheel teeth 117, Fig. 7, to ensure synchronization of the dams. They also provide position-establishing means to facilitate automatic spraying of the mould cavity with a release agent.
