The calculating machine functions as in the above Patent with the operands normally in the multi-stage recirculating input and accumulator registers 24, 38. Each register M1-M4 is identical to the input register and a b-stable 86 is actuated by the memory key on keyboard 8 to select whether the input register or one of the memory registers is to be used. One of the memory registers M1 to M4 has a number entered in it by depression of the memory key on keyboard 8, depression of a digit key on keyboard 5 corresponding to the selected memory register, depression of the constant key on keyboard 8, entry of the number via the digit keyboard 5 into the input register and depression of the memory enter key on keyboard 8 to copy the required number into the selected memory register and the accumulator register 38. Calculation is then effected as in Specification 1,261,710. Other added features.-The visual display 16 includes a sign display 16a which shows negative only, and a register 16c which indicates which (if any) of registers M1-M4 is in use.

Title: Liquid crystal cells and methods for the manufacture thereof
IPC: G02F1/1341
Filed: 1971-12-20
Abstract: 1337551 Modulating light ELECTROVAC FABRIKATION ELEKTROTECHNISCHER SPEZIALARTIKEL GmbH 20 Dec 1971 [21 Dec 1970] 59102/71 Heading H4F [Also in Division G5] A liquid, crystal cell comprises a plurality of stacked glass plates 1, 2 sealingly joined at their edges 6, the spacing between the or each two adjacent plates being determined by a single layer of spaced grains 3 therebetween, the mean grain spacing being, e.g. ten times, greater than the mean grain size, and the space between the plates being filled with liquid crystal (e.g. nematic) material 10. Such a plate is produced by covering a first plate with grains of a grain fraction having limits which, with an upper limit #25Á, differ by #6Á, or with an upper limit >25Á, differ by #25% of the upper limit, the grains being applied by sieving, spraying, screen printing or vibration distribution. It is also possible to retain only the large grains by gripping them between the plates and shaking the others out. The grains are covered with the second plate and the process repeated until the desired stack is produced. The stack is heated and subjected to pressure, the plate edges being joined by welding or glass solder. Depending on the relative softening points of the plate and grain materials, the stack is raised to a temperature at which either hard grains penetrate the plate material or the grains are squashed between the plates, Figs. 4 and 5 (not shown) whereby uniform plate spacing results despite the tolerance on grain size. The cell may be curved at the same time, Fig. 11 (not shown). One or more apertures are left at the edge of each cell, Fig. 2 (not shown), for the introduction of liquid crystal material, before hermetic sealing. The grains may be opaque, but preferably are translucent or transparent with the same refractive index as the liquid crystal, to render them invisible. The glass plates 1, 2 and grains 3 may be of the same material. The plates 1, 2 may be provided with electrode layers 11, 12, which may be patterned, Figs. 6-9 (not shown), whereby the capacity of the liquid crystal is controlled, or alternatively a magnetic field may be applied to the cell. A multi-layer cell, Fig. 10 (not shown), may include different liquid crystal materials, or different foreign (coloured) substances in the several liquid crystal layers, e.g. for use as a colour television display.

Filed: 1970-12-17
Abstract: 1281134 Programmed control of machine tools INTERNATIONAL BUSINESS MACHINES CORP 17 Dec 1970 [30 Dec 1969] 59907/70 Heading G3N A time-sharing numerical control system includes a local special purpose computer 14 inter-connected to machine tool systems 5-7 and a CPU post processor 8 providing, in advance, instructions for on-line machine tool operation. Instruction data from CPU 8 is fed to buffer registers 15-17 which are sequenced through gates 25-27 by a scan-and-select mechanism 13 which interrogates lines 100-104 as to the presence of a request for service from any one of the machine tools. Blocks 10-12, operating at a timing controlled by CPU 8, are connected to mechanism 13 through switches 83, 86, 89 which, in the down position connect to outputs of systems 5-7. Each machine tool system periodically provides a pulse indicating a request for additional data from the computer 14. The mechanism 13 then operates a line 150, 154 or 156 to enable a gate 25, 26 or 27 to connect a buffer register to the computer. The computer provides positive or negative X or Y position increment commands on lines 45-48 through a gate 70-72, as enabled by mechanism 13, to the particular machine tool control system that had requested data. When the computer 14 has completed the performance of an algorithm for a given machine tool it will then, via a line 152, cause the mechanism 13 to scan for a request by a different machine tool system.

Title: Analogue signal sorting circuit
IPC: G06K9/62
Filed: 1972-12-29
Abstract: 1354040 Arranging signals in order of magnitude INTERNATIONAL BUSINESS MACHINES CORP 29 Dec 1972 [14 Jan 1972] 60157/72 Heading H3T [Also in Division G4] A sorting circuit for sorting into order of magnitude a plurality of analogue signals comprises an analogue OR circuit for each order, each order OR circuit having inputs for receiving simultaneously all the analogue signals and an output for the largest signal of the order, and a switch for each analogue signal to each order analogue OR circuit except that of highest order, each of the switches operating to close the associated input when the associated analogue signal has been identified as the largest signal in a higher order analogue OR circuit. The arrangement is particularly intended for use in character recognition systems. Signals derived from N amplifiers, e.g. 10, 11, 12 are applied over lines 14, 15, 16 respectively to an OR gate comprising transistors 18, 19, 20 having a common emitter circuit resistor: the first largest signal appears in the collector circuit of the corresponding one of the transistors 18, 19, 20, e.g. transistor 18. The signals are also applied to a second OR circuit comprising transistors 30, 31, 32 via diode gates 40, 41, 42 respectively; one gate, e.g. 40 is however biased so that no signal reaches transistor 30 since the corresponding transistor 18 in the first OR circuit is conductive. The signals are further applied to a third OR circuit comprising transistors 50, 51, 52, each of which is again preceded by a diode gate 60, 61, 62 respectively so that no signal reaches a transistor when a corresponding transistor in a higher order OR circuit is conductive. A signal proportional to the difference between the largest input and next largest is obtained at terminal 91, by means of differential amplifier 90, which derives one input across resistor R4 and a second across resistor R8: an output is similarly derived at terminal 96 corresponding to the difference between the second and third largest inputs. The Specification also describes a modification in which the common emitter resistors R4, R8 &c. are replaced by current sources (Fig. 2, not shown) and also a modified diode gate circuit (Fig. 3, not shown).

Abstract: 1298564 Making tubes; welding by pressure or fusion NIPPON KOKAN KK 10 Dec 1969 [11 Dec 1968] 60383/69 Headings B3A and B3R A method of making a tapered tube comprises preforming a trapezial blank into an open tapered tube 3 and forging and welding the longitudinal edges 16 of the preformed tube by drawing the tube between forming rolls 1 and 2 at a speed which is n times the peripheral speed of the forming rolls, where n=2-10 and each forming roll has a shaping periphery having a length of 1/n times the length of the tube. The welding is affected by passing a high frequency current through contactors 7, 7 to the V-shaped whose angle is controlled by a roller 6. Other welding methods which may be used are resistance welding, electron beam welding, electroslag welding or arc-welding. A pressing roller 9 bears upon both edges 16 to ensure the accuracy of the join. To reduce the friction between the tube and the drawing rollers, energy of supersonic frequency may be applied.
