Title: Centrifugal pumping apparatus for liquids
Inventor: RIMMER RONALD
IPC: F04D15/00
Filed: 1965-08-31
Abstract: 1,142,637. Centrifugal pumps; gas turbine plant. DOWTY FUEL SYSTEMS Ltd. Aug. 17, 1966 [Aug.31, 1965], No.37123/65. Headings F1C and F1G. A pumping apparatus comprises a centrifugal pump of the vapour core type supplying liquid to a hydraulic load, e.g. liquid fuel to the burners 53, Fig. 1, of a gas turbine engine. Resistance to flow to the pump from a L. P. source, e.g. a boost pump 24, is increased by increasing the swirl in a chamber 32 immediately upstream of the pump inlet 16. The swirl is created by the tangential discharge of control liquid into an annular passage 28, the control liquid being supplied from the pump delivery conduit 34 through a restricted conduit 35. The swirl may rotate in the same or opposite direction to that of the impeller 14. Swirl inducing vanes may be provided between a pair of arcuate passages 29 in a flange 26. The flow of the swirl-creating control liquid is regulated in accordance with pump delivery and the degree of throttling of a by-pass line 37 for the control liquid. The by-pass line throttle 38 is adjusted by a pivoted lever 39 in accordance with flow from the L. P. source sensed through a device comprising a plug 47, bore 48 and compression spring 51, with engine jet pipe pressure communicated to bellows 43, and with engine compressor delivery pressure communicated through restrictor 40 and pipe 44 to bellows 42. The flow to the pump can be controlled by opening or closing a variable vent valve 46 to decrease or increase respectively the resistance to flow. The pump delivery may be stopped by a stop cock provided in by-pass line 37, or by additional tangential conduits opening into annular passage 28 and connected to a source of shut-off control liquid. In an alternative embodiment, Fig. 2 (not shown), which is more sensitive for low flow-rates, the spring (51) is reacted against a fixed wall, and the flow signal is communicated to the lever (39) by a diaphragm (56) moved in accordance with the pressure difference across the plug (47). The flow sensing device may be arranged in the pump delivery conduit downstream of the connection to the control liquid conduit.

Abstract: 350,462. Composite kinematograph pictures. SOC. ANON. INDUSTRIA CINEMA TEATRALE ITALIANA MUNDUS and BONETTI, A., 17, Piazza Duomo, Milan, Italy. Dec. 4, 1929, No. 37141. Drawings to Specification. [Classes 97 (i) and 98 (ii).] In producing composite kinematograph pictures, two sequences of images, comprising respectively a developed positive photograph lying directly in front of the unexposed film and images projected upon the developed positive are simultaneously photographed. The developed positive may be of actors against a transparent background and a supplementary scene in miniature placed in front of a single coloured background may be projected thereon. Alternatively a developed film of the supplementary scene may be placed directly in front of the film of the actors, so that three films pass through the camera gate in superimposition. The intensity of exposure may be controlled by adjustment of the position of the single coloured background. A camera having three film magazines and adapted to permit two films to pass through the exposure gate in superimposition is shown in the drawings. Reference has been directed by the Comptroller to Specifications 112,210 and 155,028, [both in Class 98 (ii), Photographic processes &c.].

Abstract: 1474220 Continuous casting MONSANTO CO 28 Aug 1974 [29 Aug 1973 (2)] 37502/74 Heading B3F An alloy of steel and at least 0À2% Ti or 0À5% Si by weight is melted and a mixture of inert gas and an oxygen-containing gas is maintained above the melt at superatmospheric pressure, the oxygen potential of the melt being controlled by means of the gas mixture to a level whereat the activity of the titania or silica in the melt is maintained at from 0À3 to unity, where unity is defined as the activity when the melt is saturated in titania or silica at the temperature of the melt. The melt (containing 0À01- 4À3% by weight of carbon) is extruded through an orifice as a continuous stream and into an oxygen-containing atmosphere whereby the titania or silica is caused to precipitate and form a stabilizing film about the stream which is then solidified by cooling to form a wire of less than 35 mils diameter. The inert gas above the melt may be Ar or He, with CO, CO 2 , O 2  or steam. The mixture may be introduced by bubbling up through the melt, possibly to supplement mixture supplied directly above the metal. Extrusion through a 6 mil beryllia orifice is referred to. Any of the same gases, a CO-He mixture, or SO 2  may be used as the stream-receiving atmosphere for forming a stabilizing film on the stream. He, H 2 , CO 2 , N 3  or mixtures of these may be used for cooling the extruded stream for solidification in a final step.

Preferably the reaction is effected in the presence of an acid catalyst e.g. hydrogen fluoride in the presence of a tertiary amine hydrofluoride, e.g. hydrofluorides of trimethylamine, diethylamine and morpholine, and in the temperature range from 0 DEG C. to the boiling point of the reaction mixture. N-(2-chloro-1, 1, 2-trifluoroethyl)-diethylamine is obtained by reacting trifluorochloroethylene with diethylamine.  Replacing the diethylamine by dimethylamine, diisopropylamine, dibutylamine, pyrrolidine, 2-methylpyrrolidine, 2, 2-dimethyl pyrrolidine, 4-methylpiperazine, morpholine or piperidine yields the corresponding tertiary amine.  Pharmaceutical compositions containing the above steroid compounds and having progestational, anti-inflammatory, anabolic, androgenic, and anti-fertility activity, are employed orally or parenterally as tablets, powders, capsules, pills, solutions, emulsions, suspensions, syrups and elixirs.

Title: Improvements in or relating to vibratory apparatus
IPC: B22C15/10
Filed: 1956-12-12
Abstract: 844,521. Spring-actuated vibratory apparatus. TROOST-BELCHER, I., and ROMUNTER, W. Dec. 12, 1956 [Dec. 12, 1955], No. 38005/56. Class 10. [Also in Group XXIX] In a vibratory apparatus, particularly for use in jolt ramming moulding machines, the working stroke of a piston 4, Figs. 1, 2, in a cylinder 3 is effected by the expansion of a spring 19 which is loaded, on the return stroke of the piston, by fluid pressure, a spring-loaded piston 13 slidable within the piston 4 automatically controlling the fluid for this purpose. Fig. 1 shows the piston 4, the interior of which mounts a stepped-bore sleeve 7, at the end of its working stroke. The cylinder 3, its closure 5 and the piston 4 are bored and channelled so that the pressure fluid enters at 21 and, after effecting spring loading, leaves at 22, 23. The piston 13 has shoulders 11, 12 defining with the sleeve 7 an annular space 8. To load the spring 19 fluid through 21 enters an annular chamber 30 from whence it passes through bores 24, 31 respectively to the space 8 and the space 34 below the piston 13. The fluid within the space 34 holds the piston 13, Fig. 1, against a spring 15 whilst fluid from the space 8 passes through bores 27 to an annular chamber 28 and acts upon a step surface 29 to retract the piston 4 and hence load the spring 19. Movement of the piston 4 into the " retract position allows the space 34, Fig. 2, to empty via a bore 32 into a chamber 35 housing the spring 19 and in communication with the outlet 23. The piston 13 thus moves downwardly and the fluid in the chamber 28 escapes to the outlet 22 through bores 27, a chamber 36 housing the spring 15, bores 37 and an annular chamber 38. The spring 19 immediately thrusts the piston 4 upwardly to allow the pressure fluid to again pass to the space 34 and chamber 28 to move the piston 13 and load the spring 19.

An ion beam tube for generating neutrons or gamma rays has a central ionization source comprising a wire anode 22 and a mesh cathode 21 and a surrounding target 4 which may be moved across the path of the accelerated ions when a portion of the target is depleted of reactive material. The target 4 is carried in a sleeve 26 which may be axially shifted by a threaded rod mechanism 40. With a target of sufficient size the sleeve 26 may be dispensed with. The ion beam is formed into a disc shape by focusing electrodes 23 which also act to suppress secondary electrons emitted by the target. The tube has a "static atmosphere" (i.e. there is no connection to a pump), e.g. of deuterium at a pressure of 5-10 microns with a deuterium or tritium impregnated target to produce neutrons or of hydrogen with a lithium target to produce gamma rays. The mechanism for moving the target may comprise magnetic means or a bi-metallic actuator.
