Title: Card random access data store
IPC: G06K17/00
Filed: 1964-08-18
Abstract: 1,011,947. Statistical apparatus. NATIONAL CASH REGISTER CO. Aug. 18, 1964 [Dec. 11, 1963], No. 33634/64. Heading G4M. In a card random access store, three stacks of cards 10, Fig. 1, are continuously rotated round a central shaft, a card is selected by means of selector rods 33 co-operating with coded notches 34, Fig. 5, and the released card is ejected from the stack by virtue of the momentum acquired during rotation of the stack. The cards may be sector-shaped and have magnetic information recorded thereon. The processes of card selection, ejection, sensing and restoration to the stack take place in succession during one revolution of the shaft carrying the stacks. A member 63, Fig. 5, slides in flanges provided on a top plate 61, its radial position being controlled by a follower 65 which slides in a groove 66 in the base-plate 12. During card selection the radial distance of member 63 is smallest, and projections 68 engage notches 39 in the cards to retain the selected card in the stack. The selector rods 33 remain actuated for a complete revolution of the central shaft, so that as the increasing radial distance of groove 66 causes member 63 to move outwards, the released card is ejected from the stack, its notches 39 remaining in engagement with projections 68, and its leading edge being further guided by downwardly curved member 11. When the card is completely free of the stack it falls towards base-plate 12, being assisted by vacuum ports 12c, and finally is supported by its edges on shoulders 68a, 11e, Fig. 5. The continued rotation of the central shaft then carries the card over a magnetic transducing station 25, firm contact being ensured by vacuum ports 25a, Fig. 5. After the transducing station 25, the radius of groove 66 decreases so that member 63 is driven inwards and the card slides up shoulder 11e into the bottom of the stack where it is retained when the selector rods 33 are again actuated to effect a new selection. Since all three stacks and their associated mechanisms are similar and independent, three cards may be selected and sensed during each rotation of the central shaft.

Title: An improved process for the synthesis of hydrocarbons from carbon monoxide and hydrogen
IPC: C07C1/04
Filed: 1936-12-08
Abstract: A hydrogenation catalyst containing nickel, manganese, aluminium, and silica is prepared by treating the metal oxides with a silicon ester, hydrolysing, and reducing as described in Specification 397,295.ALSO:An anti-knock motor fuel, and higher boiling hydrocarbons for use as solvents, kerosene, diesel oil, and lubricants are produced by passing a mixture of carbon monoxide and hydrogen in a ratio between 1 : 2 and 1 : 1, preferably 1 : 1,17, by volume over a cobalt or nickel catalyst at a temperature of about 200 DEG  C. and a pressure not exceeding 3 atmos., separating the product boiling below 150 DEG  C. from the higher boiling product, catalytically hydrogenating the latter above 120 DEG  C. at atmospheric or increased pressure, and fractionating the resultant product to separate fractions for use as solvents, oils, and lubricants.  The initial synthesis may be effected in a plurality of stages with removal of products between stages.  A suitable catalyst contains nickel, oxides of manganese and aluminium, and kieselguhr. The initial gas may contain, e.g. carbon dioxide, nitrogen, and water vapour.  The higher boiling products may be vaporized and passed with hydrogen over a catalyst containing nickel, manganese, aluminium, and silica obtained by treating the metal oxides with a silicon ester, hydrolysing, and reducing as described in Specification 397,295, [Group III].  In an example, the synthesis product is fractionated giving fractions boiling up to 150 DEG  C., from 150-200, and 200-320 DEG  C.  The two latter are separately hydrogenated, and the total hydrogenated product fractionally distilled.

In operation, with the terminal B<SP>1</SP> considered as reference, when terminal A<SP>1</SP> is positive and of a potential greater than, e.g. 7À7 volts, transistor Q a  operates in a Zener mode and transistor Q b  operates normally whereby the potential at 60 falls to nearly ground and causes transistor Q c  to conduct to provide output voltage V out  across resistor K L . Capacitor C also charges as indicated at 62 via forwardbiased diode D. When the terminal A<SP>1</SP> goes negative by an amount exceeding approx. 7À7 volts, transistor Q b  operates in a Zener mode and transistor Q a  operates normally. Transistor Q c  will conduct also in this event owing to the positive potential on the upper plate of capacitor C which is discharged through the transistor Q c . When this circuit is coupled to control further circuitry, Fig. 5 (not shown), an output for gating a thyristor is obtained only when the transistor Q c  is not conducting, i.e. only at and near zero passages of the supply waveform.

Title: Motor speed control circuit
IPC: H02P5/46
Filed: 1970-07-17
Abstract: 1312458 Automatic speed control HONEYWELL INFORMATION SYSTEMS ITALIA SpA 17 July 1970 [17 July 1969] 34915/70 Heading G3R [Also in Division H2] A high-speed printer is driven by a low inertia motor 1 which is associated with a photo-diode for producing a pulse each time the paper advances by one line-pitch. A logic unit receives signals related to the type of feed required, that is stepby-step, slow-skip, or fast-skip operation, and the number of pitches required per skip. The pulses originating from the photo-diode are also transmitted to the logic unit whose output provides a reference signal for determining the speed of the motor. A tachometer voltage is compared with the reference signal, and the error signal is applied through an amplifier to the motor, the amplifier providing a reversible output for driving or braking the motor in accordance with the sense of the error signal. The reference voltage generator comprises three transistors with their collectors fed through respective resistors and connected through individual diodes to a potentiometer. The transistors are selectively rendered conductive or non-conductive by the logic signals to provide four different values of the reference voltage derived from the potentiometer, Fig.3, (not shown). The motor is accelerated to a constant speed and is then braked for step-by-step operation until the motor is stopped at the instant when the number of pulses from the photo-diode equals the number set up in the logic unit by the command signal. The amplifier for energising the motor comprises a pre-amplifier T10-T14 having two differential stages and a final stage, and a current amplifier having a first stage T15, T16, a second stage T17, T18, and a final stage having pairs of power transistors T19, T20, and T21, T22, for supplying reversible current to the motor. Zener diodes Z1, Z2, stabilise the supply voltage to the pre-amplifier and the first current amplifier stage T15, T16. A positive signal applied to terminal 15 increases the potentials at points 36, 37, which are separated by diode D. The conductivity of transistor T15 is increased in relation to the transistor T16 whereby the motor is accelerated as required. Negative feedback from point 38 to point 35 stabilises the system. In a modification, only the voltage applied to the pre-amplifier stages preceding the transistors, T15, T16, is stabilised, Fig.5, (not shown). The system may also be used to control the capstan of a tape machine.
