Title: Input Device for Automatic Computers
Inventor: HIRST HANS
IPC: G06F3/06
Filed: 1966-11-02
Abstract: 1,164,458. Sensing records. ELEKTRONISCHE RECHENMASCHINEN WISSENSCHAFTLICHER INDUSTRIEBETRIEB KARL-MARX-STADT VEB. 2 Nov., 1966, No. 49085/66. Heading G4M. An image of part of a punched tape, film or printed strip 3 is projected on to an image dissection tube 6, e.g. by optical fibres, the electron image thus formed being swept across an apertured diaphragm by scanning coils 7, 8. Initially, with no scanning voltage applied to coil 7, start marks 32 are aligned with one end of a scanning field and when such a mark is detected as a result of continuous movement of tape 3, a scanning generator 23 is triggered on via gate 25 to commence scanning of a column on the tape. A timing pulse generator 30 is also started and gates data read from the tape through a gate 13 into computer 15. The timing pulse generator 30 and scan generator 23 are synchronized by circuit 31, 28, 27, 26 which restores the generator 23 to normal after a given number of timing pulse intervals, greater than the number of bits in a column. A switch 21 is also closed normally half a bit period before end of line mark 33 is detected, any deviation from this interval being converted by network 22 into a gain-control signal for amplifier 9. On a stop command 41 issuing from computer 15, capacitor 19 is charged by an amount corresponding to the number of columns overrun by tape 3. A switching device 18 is automatically adjusted to provide a corresponding output which may be stored indefinitely, and which is applied to the deflection coil 8 so that when tape 3 is again advanced, scanning is initiated where it was left off. The overrun correction voltage is decremented during the next run of tape 3 so as to prepare for the next stop command. Particular columns of tape 3 may be selected for reading by counting the start marks 32 at 36 to enable gate 38 when coincidence between the state of counter 36 and an address issued from output 40 of computer 15 is detected at 37.

Filed: 1967-10-30
Abstract: 1,239,926. Centrifugal-casting machines. HEPWORTH & GRANDAGE Ltd. 24 Oct., 1968 [30 Oct., 1967], No. 49244/67. Heading B3F. At least two C.I. dies 24, 25 are loosely cradled in aligned apertures 23 of carrier plates 21, 22 mounted on a shaft 16 which can be partrotated by a unit 19 to swing a die between a casting station having a tipping ladle 31 with an insertable spout 32 and a motor 29 for spinning the die) to an ejection station (having an ejector head 34, with cleaning-air outlets 38, reciprocated by an actuator 35, and a casting-receiving platform 37). If the machine (shown herein plan) has sufficient apertures 23 to hold more than two dies, there may be cooling stations between the two stations described and the pouring and spinning may be effected at separate stations. The shaft 16 carrying the dies 24, 25 is first moved to the right by a cylinder unit 20 so that one end of the die 24 extends around a rotatably mounted but axially-fixed coned ring 28a. A ram 30 then moves the spinning-motor 29, a coned ring 27a and the die 24 to the right so that the die is lifted and clamped between the rings. This movement, after a ¢ second delay, causes the spinning to start and the operator can then dress the mould and insert the melt spout 32. A timer stops the spinning after solidification and the ram 30 and unit 20 retract to allow the die to rest down in the apertures 23. The subsequent swing to the ejection station cannot proceed unless the casting has freed itself from the coned ring 28, as detected by an air emitter 33A and receiver 33B. The rings 27a, 28a are chromium-plated where they contact the melt, and are spacedly mounted (to reduce heatconduction) on plates 26c, 28c but can be replaced, together with the dies and aperture liners 23a, by similar components of different sizes. A cooling period is automatically allowed at the ejection station, where three adjustably-positioned blocks 39 stop the die when the casting is ejected.

Title: Weight-controlled slicing a-parauts including variable synchroni zation control
IPC: B26D7/27
Filed: 1971-10-26
Abstract: 1337871 Weight-controlled slicing-machine PETER ECKRICH & SONS Inc 26 Oct 1971 [14 Dec 1970] 49718/71 Heading A4C [Also in Division G3] A weight -controlled slicing-machine comprises a rotary knife 12 movable in a direction 14 and operable in a cutting area 10, means 24 for feeding e.g. meat loaves into said cutting area, said means comprising two sets of chains 26, 28, a slice-receiving platform 68 mounted on a conventional weigh cell 72 which in turn is mounted on a shaft 76 for upward and downward movement and is associated with a platform position controlling means 78, a conveying means 80 for removing the cut slices of foodstuff, and further conveying means to remove said cut slices for further processing and upon which may be mounted a rejection control apparatus 112. The rotary knife is driven by a variable speed motor 120 having a speed control 122 and including a manual actuator 124 for setting the speed and thus controlling the slice rate. Below the cutting area there is a slicereceiving platform 68, which is movable in the direction shown by arrow 74, associated with the weigh cell 72 for sensing the weight of the cut slices received by the platform and for initiating adjustments of both the feed rate and the knife positioning within the cutting area to accurately control the weight of the stack of slices. The conveyor 80 comprises a plurality of belts 86 and sheaves 88 mounted on a driven shaft 90 associated with a take-away control 92, the latter being used to pivot the conveyor between the tines 70 of the slice-receiving platform, to engage the underside of the cut slices and thus convey them away from the cutting area. At the instant of time in a slicing cycle at which a slice is cut a signal is received by a slice counter and selector 140 Fig. 2 from a potentiometer 128 of a circuit 130 coupled with the manual actuator 124. Upon receiving a signal corresponding to the last slice cut, a last slice signal is emitted from the counter in combination with a signal from the circuit 130, to the AND- gate 144, and causes actuation of the take-away control 92. A circuit 141 compares an actual stack weight signal from the weigh cell 72 with a received weight signal from the counter 140 and adjusts the knife position control 20 and feed rate speed control 52 accordingly. Output from a pulse generator 136, as well as the last slice signal from the counter 140, is issued to an AND- gate 152 and then causes the platform control 78 to raise the platform 68 to its uppermost position.
Patent GB-497953-A (GB)
Abstract: 497,953. Gyroscopically controlling aircraft. SOC. CIVILE D'ETUDES DE CONSTRUCTIONS AERONAUTIQUES E. C. A. June 30, 1937, No. 18232. Convention date, June 30, 1936. [Class 4] [Also in Group XX] The rotor 2 spins in a frame 3 which, when the supporting craft rotates (e.g. pitches), precesses about an axis X-X on a supporting member 7, Fig. 1. The latter is pivoted to the craft about an axis Y-Y and is caused to rock about this axis in accordance with the indications of an instrument (e.g. the air-speed indicator 8, 9) so that the precession about the axis X-X is increased in accordance with the derivative of the instrument indications. An arm 4, which is fixed to the frame 3 and to which the return spring 6 is attached communicates the precession to one end of a swing bar 10. The movements of the indicator 8. 9 rock the support 7 through the connection 12 and actuate the other end of the swing bar 10 so that a link 11 connected to the middle of the bar 10 may operate a servomotor for automatically controlling an aircraft in accordance with the pitching speed, the air speed, and the derivative of the air speed. In a modification, the response to the pitching speed is rendered negligible by reducing the inertia of the gyroscope or its spin and causing the instrument 8, 9 to rock the support 7 through a relay and a mechanical gearing-up transmission. The relay may be controlled by two or more instruments (e.g. an air-speed indicator and a vertical accelerometer). In a further modification, Fig. 3, the frame 3 precesses about the axis X-X in a ring 30 pivoted to the aircraft about an axis Y-Y and adapted to be rocked about this axis in accordance with the precession about the axis X-X. The arm 4 controls a servomotor 17 driving a crank arm 34 on the shaft 35, to which is also fixed an arm 33 connected by a link 32 to a crank arm 31 on a trunnion of the ring 30. A link 11 attached to the arm 34 operates a servomotor for automatically controlling the craft in accordance with the sum of an infinite series, the terms of which comprise the pitching speed and successive derivatives thereof. A hydraulic brake 40 is provided to limit the speed of movement. The construction shown in Fig. 3 may be modified by eliminating the servomotor 17 and causing the precession of the frame 3 to rock the ring 30 about the axis Y-Y directly. To effect this, a trunnion of the frame 3 extends through the ring 30 and carries a crank arm connected by a link to a fixed point. The arrangement shown in Fig. 3 may be combined with that shown in Fig. 1, the support 7, Fig. 1, being pivoted in supplementary frame actuated by the instrument 8, 9 and being rocked in this frame by the precession of the frame 3 by a connection similar to that shown in Fig. 3.
