Title: Improvements in axial piston pumps or motor devices
IPC: F01B3/00
Filed: 1965-03-19
Abstract: 1,072,215. Hydraulic reciprocating motors and pumps. ROBERT BOSCH G.m.b.H. March 19, 1965 [March 20, 1964], No. 11659/65. Heading F1A. In an axial piston, fixed or variable-displacement motor or pump having a revolving cylinder block 18 spring-loaded against a ported valve plate 11, tilting of the block away from the valve plate is counteracted by the provision of a central valve plate recess 33, connected to casing space 45 via cavity 26 and splines 17 and to the low pressure side of the pump or motor via spring- loaded check valve 36, and peripheral recesses 40 connected directly to the low pressure side, so that during operation, the pressure in the casing due to leakage collected by recess 33 acts to bias the block against the valve plate. The pressure in recess 33 is greater than that in recesses 40, due to the spring-loading of valve 36. Recesses 40 may contain segmental bearing lands. Recesses 33 and 40 may be asymmetrical Fig. 4 (not shown). In another embodiment Fig. 6 (not shown), the central recess communicates with the low pressure side via an adjustable throttle constituted by a shuttle valve (47) controlling passage (35). Liquid from recesses 40 passes to the low pressure side via a throttle passage (52) in the shuttle. Movement of the block away from the valve plate results in increased flow from recesses (40) through passage (52), causing a pressure differential which moves the shuttle against its spring to close passage (35), and increase the pressure in recess (33), which then acts to increase the loading of block (18) against the valve plate. Shuttle movement is damped by a piston portion having a throttled passage 59. In a further embodiment, Fig. 7 (not shown), the casing is connected to the low pressure side via a spring-loaded check valve (66) in the cylinder block, the loading on the valve being increased by centrifugal force on rotation of the block, so that the loading on the block is proportional to the speed of rotation. In another embodiment, Fig. 8 (not shown), the central valve plate recess is permanently connected to the low pressure side, and the peripheral recesses communicate with the casing and with the low pressure side via a spring-loaded and centrifugally-loaded check valve in the cylinder block.

Title: Improvements in or relating to Magneto Ignition Systems.
Filed: 1916-08-17
Abstract: 102,606. Soc. de Paris et du Rhone. Dec. 6, 1915, [Convention date]. Systems, elec. tric.-To produce simultaneous sparking across the terminals of a pair of plugs connected to separate magnetos, the primary windings of the two magnetos are connected in parallel. A s shown in Fig. 1, the primaries of the two magnetos 3, 3<1> are connected together through the contact 7 of a rotary switch 6, the contact-arms 13, 14 of the interrupters being earthed at 1. If, owing to different settings of the interrupters, one of them, for example 2<1> opens its circuit before the other, sparking fails to occur in consequence of the primary of the magneto 3' being short-circuited through the second interrupter 2, the contacts of which are still closed. When the primary of the magneto 3 is broken by the interrupter 2, sparking occurs at both plugs. The switch 6 has two earthed contacts 8, 9, which enable either or both of the magnetos to be cut out of action. In the event of one of the interrupters being impaired, the contacts remaining apart, sparking will continue simultaneously at the two plugs.

Filed: 1952-05-15
Abstract: <PICT:0723629/III/1> Heavy hydrocarbons such as reduced crudes and pitches are cracked in liquid phase to give lower boiling hydrocarbons and coke, the slurry of cracked oil and coke are separated by gravity into a thickened slurry and clarified oil, the thickened slurry is coked in a further coking stage and the clarified oil is catalytically cracked, preferably in a fluidized solid cracker.  The thickened slurry is also preferably coked in a fluidized solids bed and vapours from the coking stage passed to the clarified oil cracking stage or to the final product fractionator. As described in an example, heavy oil feed, preferably diluted with lighter oils and mixed with seed coke from a tank 7, containing a slurry of coke in fresh feed, naphtha, kerosene or product bottoms, is fed via line 1 to heating coil 11 (800-850 DEG F.) and soaker 17 where it is maintained above 800 DEG F. and at 1000-3000 p.s.i. pressure for 5 minutes to 2 hours or more.  Feed velocity in coil 11 should be sufficiently high (4-10 ft. or more per second) to prevent coke deposition in the coil.  In tank 17 the feed is agitated by paddle 19.  Cracked products are led by line 21 to settler 25, being cooled below cracking temperature by mixture with cooled clarified oil from line 22.  From settler 25 slurry is drawn off to fluidized solids coker 59 and possibly to slurry tank 7.  Any quantity of the slurry may be passed through mill 65 to reduce the coke size to a suitable value.  Clarified oil is taken off at 27, part recirculated via cooler 30 to the settler 25 and the remainder fed to catalytic cracker 31.  From cracker 31 products are fed to product fractionator 35.  Overheads from coker 59 may be fed either to cracker 31 or fractionator 35 by line 91.  Light or heavy naphtha may be fed from product lines 39, 41 by line 53 to slurry tank 7 to dilute the feed. From coker 59 product coke may be taken off at 77 and part utilized as seed coke for fresh feed.  Bottoms from fractionator 35 may be recycled to cracking stage 31 or passed by line 87 to coker 59 or part or all returned to coil 11 by lines 89, 55 and 9.  The Specification gives permissible ranges for temperatures, pressures and residence times which are somewhat wider than those specified in the example.  Specification 734,509 is referred to.
