Abstract: 1,094,522. Fuel injectors and igniters. H. PAPST. Feb. 10, 1965 [Feb. 10, 1964], No. 5818/65. Heading F1B. A combined fuel injector 1 and incandescent igniter 2 comprises a thermally insulating flask 21 having interconnected recesses through one of which the fuel is injected and in another of which the igniter 2 is disposed. The fuel flows along a stem 11 which may have a projection 23, Figs. 22-24 (not shown) to scatter fuel droplets towards the igniter 2 to facilitate ignition. The fuel injector is clamped in position by a clamp 4 carrying a spring-loaded contact 14 carrying current to the igniter terminal 17. A projection 9 on the injector engages a slot in the nozzle holder 20 to ensure correct location of the injector. The igniter 2 may comprise an incandescent wire or a spiral heater of molybdenum, tantalum or tungsten covered by quartz powder or a ceramic. In Fig. 20 the igniter 2 is replaceable and is held in position by a spring clip 22, the upper end abutting a slidable member 46 in contact with a sealing member 50 of a deformable metal.

Title: Process for the continuous treatment of hydrocarbons
IPC: C10G21/10
Filed: 1927-03-02
Abstract: 275,884. Imray, O. Y., (Allgemeine Ges. f³r Chemische Industrie). March 2, 1927. Mineral and tar oils, purifying. - In a process for the continuous treatment with liquid sulphur dioxide of hydrocarbons obtained from the distillation of coal tars, tars from brown coal, kerosene, transformer oil, light lubricating oil and the like, the resulting fractions are subjected to a continuous evaporation process divided into several pressure stages in the last of which a high vacuum is employed. The hydrocarbons enter a mixer 3 by a pipe 1 and sulphurous acid by a pipe 6. Pipes 21, 22 conduct the purified oil and the extract respectively to main evaporators 15, 18 heated bv steam. Acid is led bv pipes 29, 30 back to a tank 4 and the oil is taken by pipes 32, 33 to steam heated evaporators 16, 19. Cold acid is mixed with the sulphurous acid taken off by pipes 37, 38 in a mixing tube 40, the hydrocarbons are drawn off from a pipe 43, and acid is conducted by a pump 36 to the tank 4. The oil from the evaporators 16, 19 is carried by pipes 46, 47 to evaporators 17, 20 maintained at low pressure by a vacuum pump 50 and the acid vapour passes through a cooler 54 and is pumped to the tank 4. Hydrocarbons are withdrawn from pipes 60, 61, 57. Specification 114,845 is referred to.

Filed: 1967-02-08
Abstract: In a process for the catalytic reforming of hydrocarbon oil, the oil is passed in serial flow through n reactors (n being at least 3) until the catalyst activity in at least one of the last two reactors has declined appreciably, one of the last two reactors is then removed from service and regenerated while continuing serial hydrocarbon flow through the remaining n - 1 reactors, the regenerated reactor is returned to service in series flow, the second at the last two reactors is removed and regenerated while continuing serial hydrocarbon flow through the remaining n - 1 reactors and the regenerated second reactor is returned to service, the catalyst in the remaining n - 2 reactors being regenerated only during periods when no reactor is in service, the octane number of the reformate product obtained with n - 1 reactors in operation being lower than that obtained with n reactors in operation.  In a preferred embodiment there are 4 reactors and the catalyst is distributed in the ratio 1:1:3:3.

Abstract: 1,068,768. Gear pumps and motors. ROBERT BOSCH, G.m.b.H. Feb.11, 1966 [Feb.12, 1965], No. 6004/66. Heading F1F. A gear pump or motor having at least two intermeshing toothed wheels, as shown two, 14, 15, Fig.1, sandwiched between bearing bodies 12, 13 supporting a drive or driven shaft 16 and a stub shaft 17, includes on the bearing body faces adjacent the wheels recesses (58), (59), Fig. 3 (not shown) communicating with the low pressure recess (38) which extends across the housing body 10. The recesses (58), (59) also communicate with annular grooves 51, 53, 54, 56 around the shafts adjacent the wheels which in turn through longitudinal grooves 46, 47, 48, 49 respectively communicate with similar annular grooves 50, 52, 55, 57 remote from the wheels. These latter annular grooves are connected to grooves 44, 45 at opposite ends of the body 10 which are in turn interconnected by passages 62, 63, 64, 65 through the bearing bodies 12, 13 which are open to the tooth spaces and offset towards the low pressure recess (38) from a plane in which lie the axes of the shafts 16, 17. Operating as a pump, with the shaft 16 driven clockwise, as seen from the left Fig. 1, pressure medium sucked in through the recess 38 produces a vacuum in the enlarging tooth spaces to suck in the pumped medium into the recesses (58), (59) which passes through the annular grooves 51, 53, 54, 56, longitudinal grooves 46, 47, 48, 49, annular grooves 50, 52, 55, 57 and passages 62, 63, 64, 65 to give "suction-lubrication" of the bearings. Operating as a motor, with the shaft 16 being driven anticlockwise on high pressure medium being admitted to a high pressure recess (39) extending across the body 10, pressure medium in the recess (38) is squeezed into the tooth spaces between the wheels to circulate through the grooves and passages in the opposite direction to lubricate the bearings.

Patent GB-591914-A (GB)
Title: Improvements in and relating to door locking means
IPC: E05B65/26
Filed: 1945-03-13
Abstract: 591,914. Latches. CLARK, J. A. March 13, 1945, No. 6287. [Class 44] In locking means for doors, particularly vehicle doors, in which an outer handle is operatively connected to a latch and means are provided for uncoupling the handle from the latch spindle, the said means comprise a sleeve or collar secured to the spindle, within which an extension or spigot on the boss of the handle is accommodated, and means for locking the sleeve to the spigot, for example, a barrel lock which actuates a transverse bolt mounted in the spigot and engaging a recess in the sleeve. Alternatively the sleeve and spigot may be locked together by the engagement of clutch members on axial movement of the spindle. In the form shown in Fig. 1, in which the door can be locked from outside, the spindle 1 has on its outer end a sleeve 2 recessed to receive the spigot 4 of the handle 5. The handle boss 6 is provided with the usual revolving barrel lock 7, the operation of which engages or disengages the handle from the spindle, for example, by the action of an eccentric pin 9 engaging a slot in a transverse bolt 11, the outer end of which engages in a recess in the sleeve 2. Spring-pressed balls 14 located in radial slots in the spigot 4 locate the parts in correct position for engagement of the bolt 11. In a modification, the bolt 11 may be shot by a spring, the lock 7 retracting the bolt, which is then retained by a spring-pressed ball or the like. Alternatively the bolt may be retracted by a spring, and shot by the lock. Where it is desired to lock the door from the inside, coupling and uncoupling may be effected by axial movement of the spindle, the outer end of which carries a sleeve in which is located a spigot on the handle, with pin and slot or dog clutch engaging members provided in or on the sleeve and spigot. To effect axial movement of the spindle a rotary cam member 25, Fig. 3, rotating with but slidable on the spindle 27 is housed in the boss 23 of the inner handle, and engages a cam face thereon. During normal operation of the handle, the boss and cam member rotate together, being held in engagement by a spring 39. To uncouple the outer handle, the inner handle 24 is given a further anti-clockwise turn, when a shoulder on the cam member 25 engages a pin 32, preventing further rotation of the cam and causing the boss 23 and the spindle to move inwardly. The collar 41 on the outer end of the spindle has a slot 44 in which engages a dog 45 on the spigot 42 of the outer handle ; the inward movement of the spindle disengages these parts.
