Patent GB-663010-A (GB)
Title: Improvements in or relating to regenerating solid catalyst particles
IPC: B01J8/26
Filed: 1949-07-06
Abstract: <PICT:0663010/III/1> <PICT:0663010/III/2> In the regeneration of catalyst particles in the fluidized condition by burning off the combustible deposits in air or other oxygen containing gas, the effects of "after-burning" are controlled by continuously determining the rate of change of the carbon-monoxide content of the gases in the "dilute phase" and manually or automatically decreasing the temperature of the "dilute phase" in the regenerator, for example, by the addition of water, when the rate of change exceeds 0,1 per cent per minute.  Regeneration may be effected with a catalyst "boiling bed" or by catalyst entrainment and apparatus is described for bleeding off a portion of the gases in the dilute phase to a carbon monoxide detecting unit.  The process is applicable to the regeneration of catalysts employed in the conversion and cracking of hydrocarbons.  For estimating the carbon-monoxide content, a split-beam infra-red gas analyser (Fig. 3) is employed.  Infra-red radiation from a source 2 is reflected from mirrors 3, 4 to provide two separate beams which pass through the gas-sample cell 5 and then through either a filter cell 6 or a compensator cell 7 on to the resistance arms 8, 9 of a Wheatstone bridge, the condition of electrical balance of which is amplified at 15 and recorded at 16. Trimmers 10, 11 are provided to control the amount of radiation reaching the sample cell.  To ensure the attainment of a clear cell optical balance point, a rotatable sample cell (Fig. 4) having non-parallel transmitting faces 26, 27, is preferably employed.

Abstract: 959,468. Mechanical switches, without quick action. S. SMITH & SONS (ENGLAND) Ltd. May 23, 1962 [May 23, 1961], No. 18651/61. Heading H2B. In a device comprising two levers 1 and 4 (for control of heating and ventilation in a vehicle), one of the levers is slidable longitudinally to operate a switch, but when both levers are turned to one limit of travel the switch (if closed) is automatically opened. The levers 1 and 4 are pivoted on opposite sides of a base-plate 3 by a common pivot 2 and each drives a sector plate 10 and 16 respectively and are adapted to operate flexible control cables (not shown). Spring plungers, such as 13, co-operate with notches on plates 10 and 16 to locate the levers in selected positions. The lever 1 is slotted at 5 and passes through an upturned edge 11 of plate 10 so that the lever can be pushed in to cause a sliding contact 6 tobreak connection with an arcuate contact strip 7 and ride up on an insulating ridge 9. A member 17 with cam surface 18 is freely pivoted at 19 on base-plate 3 and has a tongue 23 which lies in the path of a peg 21 projecting from plate 16 through a slot 22 in the base-plate 3. When lever 4 is moved to its end position, as shown, the peg 21 moves cam surface 18 into the path of a peg 20 on lever 1. Thus, if contacts 6 and 7 had been previously closed they are opened as soon as lever 1 is moved to its corresponding end position. When either lever 1 or 4 is not in this end position the contacts 6 and 7 can be opened or closed manually by sliding lever 1 in or out. Specification 959,469 is referred to.

Abstract: 530,713. Fuel injection pumps. BOSCH GES., R. June 29, 1939, No. 18924. Convention date, July 30, 1938. [Class 102 (i)] A fuel injection pump for an internal combustion engine, having a piston 4 which is rotatable to vary the delivery by means of a control rod 7 which is common to a number of cylinders has an intermediate member 9 located between the control rod and the piston and adapted to be individually axially adjusted from outside the pump casing to rotate individual pistons independently of their rotation from the common control rod. A cam 2 reciprocates the piston through a follower 3 and the delivery is varied through the control edge 5. The control rod has inclined teeth engaging corresponding. teeth 8 on the member 9 which is slotted to receive projections 11 on the piston so that adjustment of the control rod normally rotates all the members 9 and pump pistons to the same extent. For the individual adjustment the member 9 is slotted to receive an eccentric pin 16 on a pin 15 locked by a member 18. Rotation of the pin 15 causes axial adjustment of the member 9 which is also rotated through the helical teeth 8 to rotate the piston 4. In a modification, the control rod 7<SP>1</SP>, Fig. 4, has straight rack teeth and the member 9<SP>1</SP> is in two parts connected together by helical splines and grooves 24. The outer part 22 is moved axially by means of a screwed rod 20 and sliding member 21, this movement causing, through the splines, rotation of the inner part 91 which is axially fixed and imparts its rotation to the piston. Instead of the rod 20 an adjusting pin 15 may be used with this modification. In some cases the piston may have an inclined upper edge which may be parallel to the lower inclined edge so that shafting of the governor rod adjusts the start of the injection of all the pumps or the upper piston edge may have a different inclination from the lower edge so that adjustment alters not only the start of the injection but also the amount of fuel delivered.
