Title: Improvements in or relating to the catalytic cracking of hydrocarbons
IPC: C10G11/18
Filed: 1949-11-15
Abstract: <PICT:0659566/III/1> A hydrocarbon oil fraction is cracked in the presence of a siliceous cracking catalyst, the spent catalyst is regenerated and then re-used in the cracking stage; at least part, e.g. 20 to 50 per cent of the regenerated catalyst being contacted, before re-use in the cracking stage, with a hydrocarbon oil fraction of boiling range different from that of the fraction which is cracked, whereby aromatic constituents are adsorbed on the regenerated catalyst.  Crude petroleum oil is fed through line 1 into distillation zone 10 from which gas oil (b.r. 400-700 DEG  F.) is withdrawn through line 4, and lubricating oil (b.r. 650-900 DEG  F.) is withdrawn through line 5.  The gas oil is introduced into cracking zone 20 which is supplied with regenerated silica-alumina, e.g. 85 per cent SiO2+15 per cent Al2O3, catalyst through line 7.  The cracked products are withdrawn through line 9 and passed to distilling zone 30. Spent catalyst is withdrawn from zone 20 through line 8 and passed to regenerator 40 which is supplied with air and steam through lines 13 and 14 respectively.  A portion of the regenerated catalyst which is withdrawn from the bottom of the regenerator, is passed to zone 20 through line 7.  Another portion of this regenerated catalyst is segregated by means of line 15, passed through a heat-exchanger and a cyclone separator 16, and then fed alternately to zones 50 and 60 where it is brought into contact at a temperature in the range 125-150 DEG  F. with the lubricating oil preferably diluted with liquid propane, butane, or a light naphtha separated in zone 30 and introduced into line 5 through line 17. The catalyst removes aromatic constituents, sulphur compounds, resins and gum-forming materials selectively from the oil.  The catalyst is separated from the oil in filter 80 where it may be washed with additional diluent introduced through lines 17 and 24. The oil is passed through heater 19 into distillation zone 70 where the diluent is vaporized and taken overhead, while the lubricating oil is withdrawn through line 22.  The catalyst withdrawn from filter 80 through line 23, is heated and subjected to mild purging to remove diluent (but leave the adsorbed aromatic constituents) and is then introduced into cracking zone 20 through line 7.

Title: Improvements in or relating to clutch release mechanisms
Inventor: HALE RONALD FREDERICK
IPC: G05G7/04
Filed: 1963-07-26
Abstract: 1,025,105. Clutch control; friction clutches. FORD MOTOR CO. Ltd. July 17, 1964 [July 28, 1963], No. 29634/63. Headings F2C and F2L. Relates to a motor vehicle clutch control wherein a diaphragm - spring - engaged plate clutch is disengaged by a clutch release pedal 47 through a mechanical, or, as shown, hydraulic transmission, and wherein the force required to deflect the diaphragm spring for disengagement, determined by the load/deflection characteristic of the spring and the load/ compression characteristic of the clutch disc 13, rises to a maximum, decreases to a minimum, and then increases again. In such a control, to avoid the disconcerting decrease in release pressure on the pedal, the mechanical advantage of the release system decreases after the force on the diaphragm spring reaches its maximum such that the pressure on the pedal substantially does not decrease during said decrease in force on the diaphragm spring. The clutch comprises a diaphragm spring 33 fulcrumed at 35, 37 on the driving clutch casing 21 and acting on a presser plate 27 connected to the casing by chordally disposed flexible drive straps 31. The clutch disc 13 comprises friction linings 41, 43 separated by circumferentially extending corrugated spring plates. As shown, the clutch release pedal 47 acts on the diaphragm spring through a master cylinder, not shown, a slave cylinder 59, a lever 55, struts 69 of a C-shaped link 67, a hub 51 and a release bearing 49. The pedal is so arranged in relation to the vehicle driver that during release movement the point of pressure application on the pedal is transferred progressively from a point P1 to a point P2, whereby the pedal moment arm length is reduced from a value A1 to a value A2, and the push-rod of the master cylinder is so pivoted to a bracket 61 of the pedal about an axis Y parallel to the pedal pivot axis X that during release movement the pushrod moment arm length is increased from a value B1 to a value B2. The mechanical advantage of the system is thereby decreased from A1/B1 to A2/B2 throughout the release movement. During return movement of the pedal, the moment arm length of a pedal return spring R1(R2) increases from a value C1 to a value C2.

Title: Improvements in or relating to valve structures
IPC: F15B13/04
Filed: 1952-11-25
Abstract: 729,673. Valves. GARDNER, L. H. Nov. 25, 1952, No. 29776/52. Class 135. A valve controlling the supply and exhaust of pressure fluid to and from a pressure-actuated device comprises a body 10, Fig. 1, having inlet, exhaust and work chambers 12, 14, 16 respectively connected to a pressure source, atmosphere and the actuated device, e.g. a singleacting motor 70, and a pair of interconnected valve members 34, 52. The valve member 34 urged towards its seat by a spring 40 is slidable in a sleeve 28 which communicates at all times through a bore 82 with the work chamber 16 to eliminate any dashpot action of the valve. The valve member 52, urged towards its seat by a spring 58, is engageable by the stem 62 of the valve 34 and slidable in. the bore 50 of a cap member 46. The bore 50 communicates at all times with the atmosphere through a bore 84 in the stem 62 and the clearance between the valve member 52 and an operating member 66 operable on the energization of a solenoid 68 to unseat the valve 34 and allow the seating of the valve 52 by its spring 58. On de-energization of the solenoid, inlet pressure acting on the larger downwardly presented areas of the valve 34, together with the spring 40, urges the valve 34 closed and through the stem 62 unseats the valve 52. As shown, the valve member 34 controls flow between the inlet and work chambers and the valve member 52 flow between the work and exhaust chambers. In a modification, Fig. 3 (not shown), the valve 34 controls flow between the work and exhaust chambers and the valve 52 flow between the inlet and work chambers, in this case the solenoid is de-energized when the inlet and work chambers are connected together. The solenoid 68 may be replaced by a hand-lever 168, Fig. 4, having a cam surface 174 engageable with the operating member 66.
