Patent GB-562202-A (GB)
Title: Improvements in or relating to remote control apparatus
IPC: B64C25/22
Filed: 1942-11-17
Abstract: 562,202. Hydraulic apparatus. MESSIER AIRCRAFT EQUIPMENT, Ltd. [formerly Rubery Owen Messier. Ltd.], and HADEKEL, R. Nov. 17, 1942, No. 16266. [Class 69 (ii)] In a remote control apparatus, e.g. for use in aircraft in which a hydraulic pump and motor are controlled electrically from a distance, a hold-on relay in the control circuit is connected to a switch operated by the liquid pressure apparatus whereby the hold-on is released at completion of the fluid pressure operation. As shown, depression of button 70 at the control station closes switch 73, 74 thereby energizing solenoids 35, 41 and opening inlet and exhaust valves 15, 21 connected to opposite ends of a jack 19. Simultaneously, hold-on magnet 80 is placed in circuit and a solenoid 59 is energized to open a valve 57 thereby releasing pressure on a declutching jack 53 and clutching the pump 11 to its motor. Jack 19 then operates, and at the end of its stroke pressure builds up to open valve 46 admitting pressure to the declutching jack and opening a switch 62 to break the electrical circuit. Valve 57 closes and the pump is declutched. A second push button 71 is provided to control inlet and exhaust valves 16, 20 for reverse operation of the jack and the two push buttons may be interconnected whereby one is held in the off position when the other is operated. An additional switch 90 may be provided in the hold-on circuit, whereby operation of the jack 19 may be interrupted at any stage. In a' modification, pressure on the line 52 opens a byepass between the pump inlet and outlet instead of actuating a declutching jack. Valve 57 may be omitted, in which case pressure acts on a piston to open switch 62 under control of a valve which operates the declutching jack. Specifications 461,453, 551,527 and 557,525 are referred to.

Filed: 1946-05-31
Abstract: 621,053. Filters. TECALEMIT, Ltd., and LE CLAIR, C. C. S. May 31, 1946. No. 16676. [Class 46] [Also in Groups XXIX and XXXIV] An oil filter includes a control valve member which allows unfiltered oil to return to the sump from the filter through a subsidiary outlet when the pressure of filtered oil in the main outlet passage exceeds a predetermined value. The control valve member comprises a valve head 29 having a dirt-cutting edge 30 co-operating with a valve seat 16A surrounding a passage 18, in a screw plug 17, which communicates through ports 20 and annular groove 19 with the oil inlet side of the filter, the head 29 being connected by a spindle 28 with a piston 31 permanently exposed on one side to the filtered oil pressure from the main outlet 3A via a passage 37, and on the other side both to the unfiltered oil pressure and to the thrust of a control spring 34. When the filtered oil pressure exceeds that of the spring 34, the valve head moves away from its seating to permit unfiltered oil to flow to the sump through a subsidiary outlet 4. The area of the valve head 29 is equal to the area of the piston 31 to ensure that the unfiltered oil pressure acting on opposite ends of the control member is balanced. Unfiltered oil reaches the piston 31 via an annular groove 24 in a plug 22, straining element 27, ports 26 and passage 23. The filter is also provided with the usual spring-loaded by-pass valve to allow unfiltered oil to pass to the bearings in the event of the filter element becoming clogged. Specification 556,304 is referred to.

Abstract: 1,055,552. Dispensing beverages. CORNELIUS CO. April 22, 1964 [Feb. 26, 1964], No. 16739/64. Heading A4T. In the dispensing of coffee which has been preserved by carbonation, coffee stored under a constant pressure of carbon dioxide gas is conducted through a line 14 controlled by a solenoid-operated valve 15, through a sensing coil 16 and line 17 into a preheating coil 19 connected at its opposite end to a spray nozzle 20 in a chamber 21 which has at its lower end a heater 23. As pressure is reduced on issuing from the spray the beverage gives up the carbon dioxide, which is vented through a valve 22, and the decarbonated beverage settles to the bottom of the chamber to be maintained at serving temperature by the heater 23 until it is drawn off through a dispensing valve 25. Control means 28 including an electrode 29 operates valve 15 in response to the level of beverage in the chamber 21. A sensing element 32 controls heater 23 and as cool beverage flows through coil 16 heater 23 is energized to augment the heat in chamber 21 before any actual lowering of the temperature of the ready coffee beverage.

Patent GB-992823-A (GB)
Title: Hydrogenative cracking of hydrocarbon oils
IPC: B01J23/50
Filed: 1963-04-29
Abstract: Hydrocarbon oils are hydrogenatively cracked by contacting at elevated temperature and pressure with a catalyst comprising silver intimately associated with an acid acting support comprising 50% to 90% by weight silica and 10% to 50% alumina, the intimate association having been achieved by contacting the support in hydrogel form with a solution of a silver salt, e.g. silver nitrate.  The catalyst preferably contains by weight 0.1% to 20% of silver, 0.1% to 5% fluorine and a Group VI, VII or VIII metal promotor.  The hydrogel support is preferably freed from alkali metal ions by treating the wet hydrogel, before or during contacting the hydrogel with the silver salt solution, with ammonium hydroxide solution at a pH of approximately 11.  The hydrogenative cracking takes place at 260% to 454 DEG  C., 35 to 210 atmos. gauge, a L.H.S.V. of 0.1 to 10 litres of oil per hour per litre of catalyst and a mol. ratio of hydrogen to oil of 5: 1 to 50: 1.  The hydrocarbon oils which boil above the gasoline boiling range e.g. 232 DEG  to 510 DEG  C. may be pretreated by mild hydrogenation to remove coke forming constituents and to reduce the sulphur and/or nitrogen content, the latter to below 30 parts per million.

Abstract: 1313465 Grinding balls S MESSERSCHMIDT [trading as SPEZIALMASCHINENFABRIK] 25 May 1971 [15 Oct 1970] 17014/71 Heading B3D A device for working balls comprises a rotary plate 1 and a non-rotary plate 2 arranged in substantially parallel relationship to define a gap therebetween in which the balls are worked, the plate 2 having an aperture or slot 23, 24 extending radially with respect to the axis of rotation of the rotary plate 1 through which balls can be inserted into and removed from the gap, and means 12 for urging the plates together in a direction parallel to the rotary axis of the plate 1, the centre of the applied pressure lying eccentric to the axis of rotation of the rotary plate and on the opposite side of the axis from the aperture or slot whereby the force per unit area acting upon the balls present in the gap increases to a maximum from entry of the balls into the gaps and thereafter decreases until discharge of the balls from the gap. The rotary plate 1 is carried by a disc 3 on a shaft 4 driven by gearing 5 and a belt 6 from an electric motor 7. The non- rotatable disc 2 is carried by a plate 8 acted upon by springs 10 abutting a pressure plate 9 on the rod 11 of a fluid pressure motor 12. The plate 2 is formed with the aperture which is divided by a central partition 30 into an entry zone 23 and removal zone 24 for the balls carried by a magazine 13. which is disposed eccentrically of the plates and driven by gearing 15, 16 from a motor 14. The aperture displaces the centre of gravity of the plate 2 by the distance x from its centre 21 to the position 20. With the point of application of the pressure at position 20 a uniform pressure acts on the balls in the gap. With the point of application moved to a position 92, the pressure increases in a curve from a minimum adjacent theentry zone to a maximum and then reduces to a minimum adjacent the removal zone. The balls are guided into the entry zone 23 and from the removal zone 24 by guides 31 on the central partition 30. Each zone is provided with linings 33,... 36 of shock absorbent material, such as nylon, the linings 33, 35 having shoes 37, 38 at their lower ends which, with the linings 34, 36, form gapes 39, 40 for the passage of the balls to and from the gaps between the plates. Guiding grooves 41, 42 are formed in the linings 34, 36 and similar grooves 45 are formed beneath the shoe 37, the grooves being aligned with concentric grooves 43 in the lower plate. Fingers 48 on the shoe 38 assist in lifting the balls from the grooves 43 in the lower plate into the removal zone 24. An eccentric drive or oscillating magnets 49 vibrates the lining 33 to assist distribution of the balls in the entry zone.
