Title: Improvements relating to liquid fuel or other pumps
IPC: F02M41/08
Filed: 1945-08-30
Abstract: 598,124. Fluid-pressure. servomotorcontrol systems. LUCAS, Ltd., J., and IFIELD, R. J. Aug. 30, 1945, No. 22358. [Class 135] In a liquid fuel &c. pump of the kind comprising a rotary cylinder block a having-spring- loaded pistons d controlled by a swash-plate e adjustable through a link q and a hollow pistonrod p from a spring-loaded piston n disposed in a cylinder, one end of which communicates through a port r with the pump outlet k and the opposite ends of which are connected through a restricted passage s, the adjustment is effected by a manually-operated piston-valve t having a central bore and radial ports z. The swash-plate is shown in the position of maximum output of the pump and to reduce the output the piston-valve is adjusted by. the cylindrical head x so that the radial ports z establish communication between the right-hand side of the piston n and the bore of the piston-rod p which communicates with the pump casing b. The consequent reduction of pressure on the righthand side of the piston results in its moving to the right, thus adjusting the swash-plate and closing the ports z. In a modification, the adjustment of the swash-plate is also controlled automatically by a spring-loaded hingedclosure valve which controls a vent communicating with the right-hand side of the piston, and which is regulated automatically by one or more conditions such as the pump speed or delivery pressure, atmospheric pressure or temperature.

Title: A combination apparatus for electrolytically promoting the flow of oil and or natural gas from a well
IPC: E21B43/16
Filed: 1957-07-15
Abstract: 851,223. Recording the How of oil from oilbearing strata. BELL, T. G., and BRUNINGA, J. H. July 15, 1957, No. 22370/57. Class 41 Apparatus for promoting the flow of petroleum oil or gas from an oilbearing strata 1, Fig. 1, to a well boring 2, comprises a positive electrode 5 in contact through an anode 4 with the oilbearing strata at a distance from the well, and a negative electrode 6, 7 in the strata adjacent the well, the electrodes being connected to a source of unidirectional electrical energy, which may be pulsated. Voltages up to 1000V may be used. It is stated that the electric current flowing through the strata breaks down the capillary force between the oil and sand &c., and promotes the flow of oil towards the cathode by electro-osmosis. The pulsed voltage is generated by a shaped cam and contact breaker 14, 15 by which pulses are of unequal duration. The cathode 7 may be surrounded by a perforated screw. In modifications, not shown, (1) An inner tube inserted in the main well bore may be the electrode and insulated from it, (2) A number of such well bores with negative electrodes associated therewith may be operated in turn from a single positive electrode at a distance of 1000 feet or more, using a rotary contact switch in the D.C. generator circuit, (3) the pulsating current may be generated by charging and discharging a capacitor, (4) the positive electrode may also be associated with a well bore, and the current periodically reversed between the two electrodes one at each well bore. Either well then serves as a delivery well.

Filed: 1925-09-08
Abstract: 240,809. Glasser, F. von. Oct. 2, 1924, [Convention date]. Automatic circuitbreakers; switches, quick-action. - In an automatic circuitbreaker in the form of a screw-plug, face contacts on the movable disc S<1> are brought into engagement with similar contacts on the fixed disc S<2> by the hand rotation of the central spindle w, through a quick-action spring f<3>, and are locked in this position against the return action of a spring f by a detent n<3> engaging the disc S<1> until released on overload by the core m<2>. Rotation of the cover to which the spindle w is attached rotates the spring f<3> which tends to drive a disc S, Fig. 4, which is retained, however, until a cam on the spindle removes a detent q<1> from a fixed toothed plate t whereupon the disc S is driven rapidly and, by means of its bent down spring portion a, drives the disc S<1>, through the projections n<1> thereon. In the closed position of the contacts, the spring portions are lifted clear of the disc S' bv their engagement with fixed projections n<2>. The disc S<1> is now retained against the return action of the spring f<2>, if no overload exists on the circuit, by the detent n<3> until tripped on overload. The device may be tripped by hand by further rotation of the spindle which, acting through a cam e<1> and a thrust rod 2, removes the detent.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 2, 1935.] [Class 73] Measurement marks are affixed to webs of material by punching the marks from an adhesive disc of material, the punched out part passing through an aligned perforation in a metal or other disc forming a protection for the adhesive surface. The device for effecting the affixing may be enclosed in the drum of a measuring machine, or as shown may be mounted on a measuring table, and comprises a hand-operated punch 5 which punches out the mark from the adhesive disc 19 and affixes it to the material 31. The disc 19, with its protective, perforated disc 20, is rotated step by step by bevel gear 18, 29 driven by a pawl 26 operated from the punch. The bevel gear 18 is carried by a housing 12 adjustable along a stud 11 whereby several concentric rows of marking on the disc 19 can be used. In the form in which the device is carried in a measuring drum the motion of the punch is derived from an eccentric on the drum shaft ; the step by step feed for the disc is similar.

Title: Upgrading of calcareous rock phosphate
Inventor: BEN-ARI CARMELA
IPC: C05B11/02
Filed: 1960-07-01
Abstract: Calcareous rock phosphate is upgraded by calcining the rock, "wet"-slaking the calcined mass with an aqueous solution of ammonium chloride, and separating the aqueous solution of calcium chloride and ammonia thereby formed from the phosphate, e.g. by decantation or filtration.  Generally the ammonium chloride is the stoichiometric equivalent of the quicklime, and preferably the solution has a concentration of 8 to 15% by weight.  Ammonia may be recovered from the aqueous solution of calcium chloride and ammonia by distillation, and may be re-converted to ammonium chloride by introduction into an aqueous saturated sodium chloride solution which is then saturated with carbon dioxide to precipitate sodium bicarbonate which is separated.  Specification 887,000 is referred to.

Title: Process for regulating the molecular weight of polydiolefines
IPC: C08F36/04
Filed: 1964-06-05
Abstract: In a process for regulating the molecular weight of polydiolefines a diolefine is polymerized using a catalyst comprising (a) a compound of a transition metal and (b) a metal, metal hydride or organometallic compound of a metal from Groups I to III of the Mendelejeff Periodic System, in the presence of an ester of an organic acid used in 0.01 to 100 times the molar amount of the transition metal compound. Suitable esters are saturated and unsaturated aliphatic, cycloaliphatic and aromatic esters having one or more ester groups, and both the alcohol components and the acid components may be unsaturated.  Lists of catalyst components and diolefines which may be polymerized with mono-olefines, are given. In the examples butadiene-1,3 containing 0.01% isobutane, 0.01% n-butane, 0.1% butene-1 and isobutene and 0.05% trans-butene-2 is polymerized in benzene using as catalyst cobalt acetylacetonate and ethyl aluminium sesqichloride and one of the following esters:-ethyl acetate, ethyl acrylate, vinyl acetate, ethylene glycol distearate, dicyclohexyl phthalate or diallyl oxalate.
