Abstract: 221,383. Frei, A., and Walker, R. Nov. 12, 1923. Cam-actuated pumps; buckets; single-acting suction-valveless bucket pumps; multiple-acting bucket pumps; two or more barrels in series. -In a fuel pump for internal - combustion engines the suction valve 3 is freely movable in the bucket piston 2 and is carried along by the piston during both strokes. The valve stem 9 passes through a passage in the piston and carries an adjustable stop 11, which is engaged by the piston during the suction stroke. The end of the valve stem passes through a spring clip 10, so that the valve 3 does not move until engaged by the piston. The valve stem and stop 11 are accessible through ports 14 in the pump casing. The piston is actuated on the downstroke by a cam 5 engaging a roller 6 carried by an arm 7 pivoted to the piston. The return stroke is effected by a spring 8 engaging an enlarged portion 15 of the piston. During the upstroke this portion 15 may draw liquid into the chamber 16, and during the downstroke it forces this liquid through the piston 2 and valve 3 into the pump barrel, the stop 11 acting as an inlet valve to the chamber 6.

Title: Improvements in the treatment of vapours produced by cracking hydrocarbons
IPC: C10G50/00
Filed: 1928-10-04
Abstract: 327,421. Anglo-Persian Oil Co., Ltd., and Dunstan, A. E. Oct. 4, 1928. Minerol oils, purifying.-Hydrocarbon vapours produced by cracking petroleum oils, particularly by vapour phase cracking, are treated to polymerize the gum-forming components by passing them through a filter charged with pumice, coke, bauxite, &c. steeped in a solution of zinc chloride, the temperature being maintained above the final boiling point of the spirit, e.g. 200‹ C. The filter may be jacketed and the vapours after passing through the reagent may be led into the jacket to keep it at the desired temperature, or superheated steam may be used for this purpose. The filter may also be heated by a steam coil passing through it. The polymers may be removed at the base of the filter or of an adjacent dephlegmating tower through which the vapours pass. The filters may be flushed with a solvent for the polymers, e.g. the cracked spirit or gas oil and a number of filters for alternate use may be employed to make the process continuous.

Abstract: 992,651. Centrifugal compressors. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. July 25, 1962, No. 28619/62. Heading F1C. A centrifugal compressor comprises two parallel shafts 10, 11 each provided with a pinion wheel 22, 23 driven by a common gearwheel 21, and at least three impellers, each impeller being secured in overhung fashion to an end of one of the two shafts, two of the impellers (12, 13) being arranged in parallel with respect to flow, the third impeller (14) on the other shaft being arranged in series with, and downstream with respect to the combined output of, the parallel-arranged impellers. A third-stage impeller, which is axially narrower than the others, is arranged downstream of the second-stage impeller 14. Intercoolers may be arranged between the compressor stages. The impeller 14 preferably receives the same volumetric flow as each of impellers 12, 13, whereby the speed of the shafts 10, 11 and the dimensions of the shafts 10, 11 and associated pinions and bearings may be substantially equal. The axes of the gear-wheel shaft 30 and the shafts 10, 11 are parallel and in the same plane. The shaft 30 is driven, for example, by an electric motor, a diesel engine or a steam turbine. Specification 714,765 is referred to.

Title: Improvements in or relating to arc gap arrangements for arc current converters
IPC: A61L2/06
Filed: 1935-10-16
Abstract: 447,597. Arc converters. MARX, E., 431, Husarenstrasse, Brunswick, and BUCHWALD, H., 18, Huttwilderweg, Reinickendorf, Berlin, both in Germany. Oct. 16, 1935, No. 28621. Convention date, Oct. 25, 1934. [Class 39 (i)] In an arc converter, which comprises two pairs 1, 2, Fig. 1, of electrodes, each pair consisting of main and screen electrodes 3, 5, means for causing fluid to flow, as shown, in series through the spaces formed between each main and screen electrode, and means for striking an initiating arc between that pair of main and screen electrodes through which the fluid first flows, the main or screen electrode 3, 5 is recessed or provided with teeth to provide a suitable striking distance for the initiating arc and a suitable cross-section for the fluid. Lateral movement of the arc may be prevented by means of an insulating cylinder or by a further gas stream which flows inwardly to the arc through the space between the opposing pair of electrodes 1, 2. The rate of flow of the gas through the electrode 2 is reduced by arranging the main electrode 4 at a comparatively great distance from the screen electrode 6, or by using a globular electrode 4, or by arranging that the angle of deflection of the gas stream is small. The main electrode 4, Fig. 2, may be provided with a recess 20 to prevent burnt products being attached to the electrode, and the electrodes are so shaped that the footpoints of the arc are located in the " wind shade." The electrodes may be provided with teeth 12, Fig. 2, which may be adapted to give the gas a spiral movement. Vapour or liquid streams may be used and movement of the arc may be effected by a magnetic field ; the lines of force should be parallel to the electrode surfaces. Separate gas or air streams may be used for cooling the electrodes. The ends of the main electrodes may be removable. Specification 429,060 is referred to.

Abstract: 941,340. Master cylinders. BENDIX CORPORATION. Aug. 8, 1961 [Aug. 15, 1960], No. 28629/61. Heading F2F. A master cylinder comprises a first plunger 40, Fig. 1, mounted in the cylinder bore 28 and defining therein a first chamber 68 connected with an hydraulic actuating system 94, 96, and a second plunger 38 defining with the advanced end of the cylinder bore a second chamber 70 connected with a separated hydraulic system 106, 108, the plungers co-operating one with another and with abutment means 122 disposed at the advanced end of the bore 28 so that in the event of failure of one hydraulic system the other will remain operative. A helical spring 52 is disposed in the chamber 68 and held under initial compression between two movable stop members 54, 56 which are operatively connected so as to permit the plungers 40, 38 to move one towards another. In operation input force on plunger 40 causes it to move leftwardly and act through spring 52 to move the plunger 38 to the left. The plungers 38, 40 move in unison and sealing members 72, 80 cover the ports 30, 32, leading to the separate reservoir compartments 16, 18, simultaneously so as to cause pressure build-up in the chambers 68, 70. The hydraulic pressure is communicated through outlet lines 86, 98 to the front and rear brakes 106, 108 and 94, 96 respectively. The spring 52 has a higher rate than the combined rates of springs 110, 112 so that a higher pressure is available to apply the front brakes than the rear brakes. In a second embodiment, Fig. 2, communication between the second chamber 244 and the reservoir compartment 216 is effected via bores 280, 278, groove 276 and port 220. The port is sealed on movement of the second plunger to the left by a seal 284.

Ribbon feeding.-An independent electric motor drives convexly shaped ribbon feeding rollers (27-30, Fig. 1) through gearing (23) and the spindles of a pair of coaxially mounted supply spools and a pair of similarly mounted take-up spool by belt and pulley drives. Friction drive to spools.-The spool spindles e.g. (20, Fig. 4) driven from the motor are radially bored to accommodate pairs of balls (21) which are urged outwardly to engage the internal bore of the hubs of the ribbon spools. The frictional engagement is adjusted by an end screw (25) which compresses rubber plugs (24) and controls the outward urge of the balls. Spool construction.-The hubs (19) are hexagonally shaped to non-rotatively mount the spools (16). Detachable mounting.-The spools (16) and the guide strips are mounted on supports (14, 15) having slides (13) which fit into slideways (12) fitted on each side plate (10, 11) of the machine. Ribbon tensioning.-The ribbon is maintained in tension by adjustable brake shoes 14 engaging the ribbons as they pass over concave guide rollers 43. Alarm device.-Should the tension be less than a certain amount a feeler (41) operates a microswitch to cause the machine to stop and light an indicator.
