Title: Hydrocracking process
IPC: B01J23/94
Filed: 1966-12-21
Abstract: A hydrocracking process comprises contacting a hydrocarbon fraction with a hydrocracking catalyst comprising sulphided nickel under hydrocracking conditions until the catalyst suffers loss in activity, discontinuing the feed of the hydrocarbon fraction while continuing the H2 flow at a temperature of at least 700 DEG  F. and a pressure between 0 and 1500 p.s.i.g., displacing H2 from the reaction zone with a non-combustible gas, contacting the catalyst with an oxygen-bearing gas to remove carbon deposits by combustion, displacing the oxygen bearing gas from the reaction zone, sulphiding the catalyst and reinstituting the feed of H2 and hydrocarbon fraction.  The hydrogenating component of the catalyst preferably comprises sulphided nickel in amount calculated as metal of 2-10% by wt. of the catalyst, and a sulphide of a Group VI metal, e.g. molybdenum or tungsten, in an amount as metal of 2-35% by wt. of the catalyst.  The cracking component may consist of silica, alumina, magnesia or mixtures thereof or preferably a crystalline zeolitic alumino silicate containing less than 6% by wt. Na2O.  The oxidative regeneration may be carried out at 700-1100 DEG  F. and the catalyst sulphided with H2S, CS2 or t-butyl sulphide at 300-700 DEG  F.

Patent GB-747322-A (GB)
Abstract: 747,322. Calculating-apparatus. FELT & TARRANT MANUFACTURING CO. June 15, 1954 [June 26, 1953], No. 17531/54. Class 106 (1). A calculating-machine whose accumulator is cleared, as described in Specification '516,535, by disengaging detents 39 normally preventing reverse rotation of the accumulator wheels 10 by their carry springs 28, is provided with a splitting control by which the means for disengaging the detents can be rendered ineffective in certain orders, so that these orders are not cleared with the remaining orders. The detents 39 are pivoted on a cross-shaft 20 and are dis- . engaged by forward movement of a bail 42 acting through two-armed levers 61 pivoted with the detents on shaft 20. According to the invention, the bail 42 is notched, as at 102 (Fig. 2), opposite the levers 61 of the five lefthand orders, but normally these notches are bridged by teeth 105 of a slide 104 mounted on the bail so that the bail is effective to trip all the detents 39. Displacement of the slide 104 to the right by operation of a finger lever 113 moves the teeth 105 from the notches 102 in the bail 42, and the bail is then ineffective to clear the left-hand orders. The flanks 106 of the teeth 105 are bevelled so that they are able to cam the levers 61 and trip the detents to clear the left-hand orders if the finger lever 113 is restored before further key action and whilst the clearing control is still effective. The slide 105 may, alternatively, be untoothed and adapted for movement transversely of the bail. The rest of the machine follows the general lines of those described in Specifications 514,291 and .522,721. The forward movement of the bail 42 is effected by cam ends of arms 65 secured to the shaft 66 of the clearing lever 71 which is retained in its forward actuated position by engagement of a nose 73 thereon in front of a shelf 74 on a spring-actuated lever 75. Further key action is effective to trip lever 75, and release the clearing lever 71 for restoration by its spring 77, during downward movement of the actuator racks 13 so that the detents are re-engaged with the accumulator wheels before the latter are actuated by the return upward movement of the racks.

Title: Improvements in or Relating to Devices for Determining Steady- State Values of Analogue Signals
IPC: G01D3/00
Filed: 1978-12-07
Abstract: A device for determining the steady-state value of an analogue signal comprises an analogue-to- digital converter 1 which produces first and second pulses corresponding to positive and negative increments in the analogue signal. First and second counters 5 and 4 count both the first and second pulses but in different directions, each being inhibited in counting substantially at zero count and reset a timer 8 upon reaching a predetermined count. An up/down counter 9 counts up and down the first and second pulses, respectively, and a display 10 displays the contents of the up/down counter 9 when the steady-state value has been determined. When the timer 8 reaches a preset time without having been reset, it stops the first and second counters 5 and 4 and the up/down counter 9 and starts each of the first and second counters counting down clock pulses until the contents thereof reaches zero. If the second counter 4 reaches zero before the first counter 5, the up/down counter 9 counts up half the clock pulses between second and first counters reaching zero. If the first counter 5 reaches zero before the second counter 4, the up/down counter 9 counts down half the clock pulses between the first and second counters reaching zero. <IMAGE>
