Title: A Calculating Machine with a Shortened Multiplication Facility
Inventor: RAHMIG WALTER
IPC: G06C15/20
Filed: 1966-09-23
Abstract: 1,164,662. Shortened multiplication calculating machine. TRIUMPHATOR-WERKE MOLKAU VEB. 23 Sept., 1966, No. 42573/66. Heading G4B. A calculating machine having a shortened multiplication facility comprises a series of toothed multiplier wheels 7 mounted for rotation on a shaft 6, a guide frame 17 slidable past all the wheels, and sensing pins 20, 24 carried by the frame so that they may approach a side face of a wheel, the second pin 24 being movable relative to the frame to determine the engagement of an additive or subtractive drive member 28 or 27 respectively with the wheel when the pin 20 abuts the side face, the wheels having apertures such that only in a zero position can the first pin 20 pass through a wheel to permit movement of the frame and sensing pins towards the next wheel, and such that depending on the value set in the wheel the second pin may or may not pass through the wheel thus determining movement of the second pin relative to the frame. The guide frame is slidable together with a spring-biased setting pin slide, 34, and the second pin 24 is attached to a bracket 23 carried by and movable relative to the frame. The pins co-operate with a slot 8 and a bore 9 in each wheel to control direction of movement of the wheel and entry of a multiplicand into the debit or credit side of a balance finding mechanism. The bore 9 is of a diameter such that only the second pin 24 will pass therethrough. When a multiplicand has been set up in the setting pin slide and a multiplier has been set up in the multiplex wheels operation of the machine is commenced by depression of a start key. Rotation of a main shaft 25 causes an eccentric shaft 26 to actuate single-toothed members 27, 28 which, when associated with a wheel 7, will cause counterclockwise or clockwise movement thereof respectively. A lever 38 which coacts with teeth on the underside of the bracket 23 controls entry into the debit or credit side of the balance finding mechanism. When a digit 1-4 (Figs. 9 and 10) is set up in a wheel both pins engage the side face of the wheel and the wheel will be rotated clockwise one step for each machine cycle (i.e. one rotation of the shaft 25) by the member 28, and the multiplicand will be transferred into the credit side of the balance finding mechanism at each cycle. Upon return of the wheel to a zero position the pins 20, 24 engage in the slot and bore and pass to the next wheel registering a number. When a digit 5-9 is set up in a wheel (Figs. 11 and 12) the pin 24 passes through the slot 8, and movement of the bracket 23 relative to the frame brings the member 27 into alignment with the wheel to move the wheel anticlockwise during the machine cycles until the pin 20 also engages the slot 8 whereupon the next higher denomination wheel is moved one step in the additive direction by mechanism not shown. For digits 5-9 the lever 38 engages a slot in the bracket 23 and the multiplicand is repeatedly transferred into the debit side of the balance finding mechanism.

Title: Character display and recording systems
IPC: G09G1/10
Filed: 1971-09-14
Abstract: 1338127 Displaying data SIEMENS AG 14 Sept 1971 [18 Dec 1970] 42736/71 Heading G4H [Also in Division H4]  Apparatus is disclosed for supplying signals to control an electronic printer wherein the signals are derived from control signals for an electron beam of a cathode-ray tube of a data display device. As shown, a data input 12, which may be a tape or card reader or a keyboard, supplies digital signals DB to a control 13 of a store 18 which supplies the signals C indicative of characters to be displayed to a buffer store 20 at a certain clocked frequency. The signals are processed further in stages 22-24 to produce digital signals DUB, DUH representing digitally accelerating and holding voltages which signals are applied to D/A converters 25 to guide the electron beam in C.R.T. 27 along a plurality of straight strokes per character to build up an alpha-numeric display. The output stages 24 are counter devices adapted to provide an 11-bit code for each coordinate x, y, the first 3-bits being the position in a fine grid of the individual strokes of one particular character, there also being sign and intensity ("black" or "white") bits. If a printed record is required, a signal D is passed to enable an ink-jet printer 9 and to operate switches 14-16, the switch 15 connecting an enabled oscillator 19 of a lower frequency than the clock pulse source, not shown, to provide the clocking signals to the devices 20-24 so that the data is processed therein at a lower rate. All the stages in the counters 24 are also set at predetermined values except for the said three stages and the sign &c. bit stages so that each character will be built up in the same particular part of the screen 27, the printed record being produced by co-operation with write/head and paper movements brought about by a device 28 coupled to the store 18. A switch 16 removes the inputs DUB from the D/A converters 25 to prevent overload of the circuits therein in view of the lower frequency. Synchronization of printed characters is obtained by introducing signals of a succeeding character into the store 20 whilst the voltages of the present character are being applied to the plates of the ink-jet printer.

Abstract: 955,380. Mobile responding stations. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Nov. 14, 1962 [Nov. 16, 1961], No. 43033/62. Heading H4L. A mobile radio responding station for use in aeroplanes comprises a receiver, a transmitter and a bistable device such that on the receipt of a predetermined individual code signal from a ground station the device is triggered to effect readiness of the transmitter to respond on arrival of a following interrogating signal which in turn triggers the device back to its initial position. Signals picked up by receiver 1 are applied to decoder 4 which produces a pulse on receipt of a predetermined code to trigger flipflop 3. The change in state of flip-flop 3 produces an output signal which effects readiness of transmitter 2 to transmit. The following interrogation signal is applied directly from receiver 1 to flip-flop 3 and triggers it back to its initial state. This change effects trigger keying of transmitter 2 causing it to send a response signal to the ground station. This response signal may be followed by an altitude representative signal from source 5 and coded by coder 6 prior to application to transmitter 2.

Abstract: 1,091,284. Shoots and hoppers. NORTONHARTY ENGINEERING CO. Ltd. Nov. 9, 1964 [Nov. 7, 1963], No. 44065/63. Heading B8S A bunker for the storage of material, e.g. coal or coke, has coaxially disposed therein a chimney 7, Fig. 1, comprising a spiral shoot 8, Fig. 2, and a spiral curtain 9, the chimney being formed with a spiral slot 10 the width of which is constant and is such that when any portion of the chimney is embedded in a pile of the coal or coke stored in the bunker the slot in that portion will be bridged by the material although the pieces of material on the top of the pile will be able to flow through the slot in either direction as coal or coke is being charged into or discharged from the bunker. Breakdown or segregation of the coal or coke is thus prevented. The width of the slot is such that the horizontal distance y is substantially equal to, but not greater than, ten times the maximum dimension of the largest pieces in the material provided the largest pieces form the major constituent of the material. Alternatively, the distance y is ten times the maximum dimension of the pieces which form the major constituent or, when no one piece size predominates, ten times the average maximum dimension of all the pieces. The bunker comprises a body 1 and a flow 2, the latter tapering to a central discharge opening 3. Discharge from the latter is controlled by a shutter 4. The curtain is made from a steel or other metal band and the shoot from a plurality of cast metal sections, the curtain and shoot being secured together, e.g. by welding. The shoot is open to the interior of the chimney and its lower edge is located radially inwards of its upper edge. The pitch of the shoot is such that the coal or coke will travel theredown at approximately eight feet per second. The chimney is supported by a framework 11 comprising equidistantly spaced-apart channel bars 12 fixed to the floor 2, tie bars 13 and 14 extending between the bars and the shoot and curtain. The bars 12 may be secured to the body 1 by horizontal tie bars (not shown). The chimney is spaced from the floor 2 by a distance not exceeding the slot width. The upper end of the shoot is fixed to a straight inclined trough 15 which is secured to a hopper 16 which coal or coke is delivered by an endless conveyer 17. The slot 10 may be alternatively formed between the lower edge of the curtain and the upper edge of the shoot or at any position between the edges of the curtain. Two slots may be provided.

Abstract: 1463708 Automatic control of speed NISSAN MOTOR CO Ltd 16 Oct 1974 [23 Oct 1973]  44818/74 Heading G3R A fuel control system for a gas turbine engine in which the fuel is controlled in accordance with the difference between a desired speed signal and an actual speed signal, including means for producing an allowance signal corresponding to the difference between the actual engine temperature and a temperature limit and means for switching from the desired speed signal to the allowance signal when the difference between the desired and actual speeds exceeds a predetermined level. In the arrangement shown a throttle position device 15 produces a signal representing a desired speed which when switch SW1 is in the position shown is compared with the actual speed from sensor 8 in subtractor 2 to produce a signal which controls fuel valve 4 to alter the speed of engine 7. The engine speed signal also supplies the function generator 17 which produces a signal representing a temperature limit signal for that speed. This temperature limit signal is continuously compared with the sensed engine temperature at 19 to provide an allowance signal from amplifier 20. A switch control unit 13 responds to a predetermined difference between the desired speed and actual speed, such as occurs when the throttle is abruptly moved, to cause switch SW1 to move to contact b when the allowance signal replaces the desired speed signal. At the same time switch SW2 is opened to provide an integrator in the circuit and thus keys the turbine acceleration free from surging or thermal destruction.
