Title: Data processing control system
IPC: G11B20/16
Filed: 1958-05-09
Abstract: 841,508. Electric digital-data-storage apparatus. STANDARD TELEPHONES & CABLES Ltd. May 9, 1958 [May 16, 1957], No. 14903/58. Class 106 (1). In a data processing control system in which binary bits on a record represent timing pulses, the presence and absence of pulses further representing programming or control information, the pulses are passed from a reading device the delaying means having output taps connected to switching circuitry which directs the pulses to record driving means to control the timing thereof, and also simultaneously decodes the pulses for programming data processing operations. As shown, the clock track 21 on a magnetic record tape has pulses present or absent (indicated by " + " and " - respectively) in positions such as 14-19. The pulses read by head 20 are passed to delay lines 22-25 and the output taps 26, 30 are connected in parallel to OR gate 43. Thus, provided a pulse is present in one of every five positions, the output of gate 43 will be a regular series of timing pulses which are used to control the tape driving means 13 and also to gate information pulses from other tracks 53-56 to utilization device 37. The combinations of bits from taps 26-30 are applied also to five bistable flip-flops (Fig. 2, not shown) in a decoder 31; and an output is obtained on line A, B, C or D and passed to device 37 for particular five-unit combinations. All such combinations begin with a " - " and the decoding is controlled by further gating and delay circuits and a 4-pulse counter. The tape may be replaced by a magnetic drum or by photographic film read by photo-sensitive heads.

Filed: 1927-06-07
Abstract: 296,802. Cheetham, G. A., Lister, H., and Metropolitan-Vickers Electrical Co., Ltd. June 7, 1927. Electricity &c., supplying by meter; mechanism for prepaying rent of meter. - In a prepayment, meter, the tripping. device, that retains the switch, tap, or the like in operative position, is connected with the differential mechanism by a releasable connection, such as a wedge, which is released by withdrawal or replacement of the coin receptacle, so that the switch &c. is thereby rendered inoperative, and which is reset only after a predetermined number of coins have been inserted. As applied to an electricity meter, the switch 33, which may be of the kind described in Specifications 253,242; and 274,559, [Class 38 (v), Electric switches &c.], is retained, closed by a tripping-device or detent 30, the detent being operated by a push rod 28 actuated by a differentiai mechanism 12, 22 as described in Specification 286,803. The rod 28 holds the detent 30 only when a wedge 34 carried by a lever 32 is interposed between them. The lever 32 has a stop 36 engaged by the coin receptacle so that, when the latter is withdrawn or replaced, the wedge is withdrawn and the switch opened. The lever 32 is also connected through rods 40, 42 to a swinging frame 43 which is thereby rocked to bring a star-wheel 46 on a shaft into co-operation with pins 48, 50 on a disc 52 carried by a coin shaft 10 which is connected to the differential through a train of gears and a friction clutch. The frame 43 also moves a bar 84 to apply a brake 86 to the disc 12 of the differential. The shaft 44 is normally biassed by a spring 70 to a zero position determined by the contact of a pin 72 thereon with a pin 74 on a gear wheel 54 loosely mounted on the shaft. To restore the wedge 34, coins representing fixed charges are irserted and the shaft 10 turned. The star wheel 46 is turned one tooth for each coin until a pin 78 carried by a flat spring 76 enters a hole 80 in the wheel 46. At the next revolution of the shaft 10, one of the pins 48, 50 engages the spring 76 and rocks the frame 43 to disengage the star-wheel from the coin shaft, thereby withdrawing the brake 86 and inserting the wedge 34 between the rod 28 and the detent 30. A fixed wedge 82 withdraws the pin 78 so that the shaft 44 can be returned to zero again by the spring 70. Indicators.-The number of coins for the fixed charges is shown on a dial 68 carried by a shaft 62 having a notched roller 64 and detent 66. A wheel 60 on the shaft through an idler wheel 58 rotates the wheel 54 to move the zero pin 74 to a position determined by the position to which the dial 68 is set. An indicator 98 is also connected to the rocking frame to show that the rent due has been paid. Coin-slit closing-devices.-A coin-slit closing- plunger 96 operated from the differential through a lever 94 is withdrawn to open the slot, when the rent falls due, by the swinging frame 43 causing a bar 18 to deflect a resilient portion 92 of the lever 94. Reference has been directed by the Comptroller to Specification 277,667.

Title: Improvements in the manufacture and production of valuable hydrocarbons and their derivatives containing oxygen from carbon monoxide and hydrogen
IPC: B65B9/08
Filed: 1937-06-03
Abstract: A catalyst for the reaction of carbon monoxide and hydrogen to give hydrocarbons and their oxygen derivatives is prepared, prior to the reaction, by reducing a compound of a metal of the iron group, reducible to metal below 500 DEG  C., with a reducing gas at below 500 DEG  C., and treating the reduced substance in the absence of an oxidizing gas at such a temperature above 500 DEG  C. but below the melting point, and for such a time that at least a partial sintering occurs.  The reduction may be effected at about 300-400 DEG  C., or above with hydrogen-containing gases, carbon monoxide or hydrocarbons such as methane and ethane, and the subsequent heating at 600-1000 DEG  C. or above, in vacuo or in the presence of, for example, nitrogen argon or hydrogen.  Each treatment may be carried out in one or more stages at ordinary, reduced or increased pressures up to 100 atmos. or more.  The reaction of the carbon monoxide and hydrogen is effected at above 150, preferably 200-450 DEG  C., and under similar pressures.  In an example, precipitated iron hydroxide mixed with aluminium hydroxide is reduced with hydrogen at 450 DEG  C. and then heated for about 3 hours at 850 DEG  C. with nitrogen. Specifications 473,932 and 474,448 are referred to.ALSO:Hydrocarbons of more than one carbon atom and/or oxygen-containing derivatives of hydrocarbons, e.g. alcohols, ketones, esters, acids, and aldehydes, are obtained by contacting carbon monoxide and hydrogen at a reacting temperature with a catalyst prepared, prior to the reaction, by reducing a compound of a metal of the iron group, reducible to metal below 500 DEG  C., with a reducing gas at below 500 DEG  C., and treating the reduced substance in the absence of an oxidizing gas at such a temperature above 500 DEG  C. but below the melting point, and for such a time that at least a partial sintering occurs.
