Abstract: 483,521. Centrifugal pumps. GILBERT & BARKER MANUFACTURING CO. Jan. 15, 1937, No. 1238. Convention date, Jan. 15, 1936. [Class 110 (i)] In a liquid-dispensing apparatus, the centrifugal pump is primed by a displacement pump having a rotor 91, Fig. 4, mounted on the impeller shaft 84 and in a recess in an end plate 58 of the motor, the shaft having a bearing 109 engaged by a spring 115 which presses a seal ring 113 against the end plate 95 of the displacement pump. End plate 58 has a lower wall 62 with upstanding hub 63, connected by radial webs 64 to the outer wall and forming a chamber 111 which is vented to atmosphere through one of the webs. Hub 63 is extended at 119 to form aflame arrester. The plate 58 is connected to a lower casing 67 carrying the suction and air pipes 29, 40, the main discharge pipe, and the diffuser chamber 76 of the centrifugal pump. This pump has a die-cast impeller 82 apertured at 89 to enable air or gas to pass upwards through plate 96 to the geared rotors 91, 92 of the displacement pump. The upper plate 95 has an outlet port communicating by passages 101, 103, 104 with pipe 40. Shaft 84 has a bearing above the motor armature spaced from bearing 109 many times the distance between bearing 109 and rotor 91. The complete dispensing apparatus, Fig. 1, is contained within a casing 15 having a plate 19 carrying the casing 67 with main discharge 30 leading to meter 31, pipe 34, hose 35 and nozzle 36. Air pipe 40 leads to an air separator 41 with a float valve controlling the outlet to a pipe 57 connected to suction 29. The separator has an overlying float chamber leading to an air vent. The motor 21 and both pumps may be removed without breaking any pipe connections, or disturbing any adjustment of the pump parts. In a modified centrifugal pump with diecast parts, the diffuser vanes 120, Fig. 14, shaped to prevent loss of energy by eddies or cavitation, are formed as integral parts of a plate secured to one of the casings 58, 67, the other wall of the diffuser being also a die-casting secured to the other casing. The impeller consists of a disc 87 with blades 88 on one face and a collar 89<1>, Fig. 12, may be formed on the rear face to surround the apertures 89 leading to the displacement pump.

Title: Improvements in radio navigational systems
IPC: G01S1/02
Filed: 1941-01-31
Abstract: 545,880. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd. Jan. 31; 1941, No. 1286. Convention date, Jan. 31, 1940. [Class 40 (v)] A single-line guiding-beacon for aircraft &c. comprises a pair of radiating-aerials set up at an angle to each other and in the same plane, e.g. the horizontal plane, and energized in such phase relation that equal and opposed field strengths exist throughout a vertical plane bisecting the angle between the aerials, whilst the direction of polarization is the same for both radiations throughout the plane containing the aerials, the intersection of these planes giving the desired guide line. The receiving circuit comprises a rotating frame aerial associated with suitable meter indicators. As shown in Fig. 1, the beacon comprises dipole aerials Aa, Bb energized in the same phase by a source T, so that in the vertical plane bisecting the angle ATb the field strengths are equal and opposite. In the plane of the aerials the direction of polarization of the received waves is the same for both radiators, whereas the polarization differs at points above and below this plane. Both aerials carry a common wave of say 100,000 kc., and in addition each carries its own characteristic wave of say 100,035 kc. and 100,050 kc. The receiver, Fig. 3, comprises a frame aerial L1 rotating about an axis parallel to the plane of the transmitting aerials and driven by a motor D. The wave common to both transmissions is selected'by a filter Fc and is detected and passed to a meter V which gives a null reading only when the receiver is in the guide line. The separate transmissions characteristic of each aerial are also selected by filters Fa, Fb and after detection are passed to a ratio meter R which indicates by the direction of its deflection which side of the vertical bisecting plane the receiver is situated. The motor D also drives a small generator G supplying A.C. of double the rotation frequency. This serves as a datum phase which by closing the double switch S may be combined with the outputs from the detectors Fa, Fb. By observing the direction in which closure of the switch swings the pointer of the meter R, the operator ascertains whether he is above or below the plane of the transmitting aerials. The plane of the aerials Aa, Bb can be tilted with respect to ground so as to permit landing of an aircraft by keeping in this plane. Alternatively the aerials may be arranged in a vertical plane, so that polarization gives lateral guidance. In a modification (Fig. 4, not shown), the transmitting aerials are each of V shape arranged at an angle to each other in a single plane.

Title: Process of and apparatus for purifying gases obtained by distillation of carbonaceous materials
IPC: C10K1/18
Filed: 1937-01-18
Abstract: 490,932. Gas - washing processes. SCHUFTAN, P. M., and NEWTON, CHAMBERS, & CO., Ltd. Jan. 18, 1937, Nos. 1455 and 23761. [Class 55 (ii)] The constituents of highest boiling point such as naphthalene and water are removed from industrial combustible gases in a first stage washer or condenser operating at near but not below 0‹ C. ; the contingent removal of benzol followed by that of organic sulphur compounds is then effected in separate stages by washing and cooling the gas with liquid hydrocarbons of relatively low molecular weight at the same temperature as the first stage, the spent washing media being continuously separately stripped before reuse. Illuminating gas freed from tar, ammonia, and hydrogen sulphide is compressed preferably to about 4- atmospheres and then cooled to about 55‹ C. by indirect contact with an adjustable amount of purified gas in an exchanger 2. In traversing a reflux condenser 4 the gas is further cooled to about 5‹ C. in the lower part by water and in the upper by liquid ammonia or other refrigerant, moisture and some hydrocarbons such as solvent naphtha condensing, and naphthalene, gum, and traces of ammonia and hydrogen cyanide separating therewith. Naphthalene is recoverable by crystallization of liquid withdrawn through a pipe 5a. The gas is now washed with wash oil at 5‹ C. in a column 6 to extract benzol the heat of solution being absorbed by a cooling coil 6a or a cooler 8 through which the gas passes to another wash oil column 9 for removal of organic sulphur compounds. Part of the spent oil is pumped to the first column without stripping the rest passing to a still 13 through an exchanger 11, 12, in which it is heated by returning stripped oil and by waste steam. The spent oil from column 6 is similarly stripped in a still 18 and rejoins the other stream on its way through cooler 8 to column 9. The heat content of vapours from still 18 may be used for preheating the spent solvent entering still 13 associated with the later stage. The purified gas may be expanded in an engine 23. In treating 10,000 cubic metres of gas about 1À5 cubic meters of oil are used in column 6 and 5 in column 9. In a modification employing atmospheric pressure the gas is initially washed and cooled with wash oil or water to condense gum, naphthalene and water.

Abstract: 428,484. Wrenches. DEHN, F. B., 103, Kingsway, London.-(Dazey Churn & Manufacturing Co. ; Warne Avenue, St. Louis, Missouri, U.S.A.) Jan. 15, 1934, No. 1484. [Class 61 (iii)] A container cap remover comprises relatively movable jaws, means for closing the jaws to an initial engaging position, resilient means which act upon one and react upon the other jaw, and means, other than the initial means to apply tension between the jaws through the resilient means after the jaws have been moved to the initial engaging position. The container cap is gripped between jaws 9, the one fixed to a base member 1 detachably secured in a wall bracket 15 and the other to a slide 16 movable along the arms of a U-shaped rod 22. At opposite sides of its median line, the slide 16 has a cam 32, actuated by a handle and arm 34, 33, and a spring pressed rod 28 adapted to draw a slidable locking bar 26 towards the slide 16. In operation, the slide 16 is displaced outwardly to permit the cap to be placed in the device, the bar 26 moving freely along the arms of the rod 22 and eventually compressing with one of its ends a spring 37 coiled around the bend 24 of the rod. When the slide 16 is adjusted to engage the cap, the bar 26 takes up an oblique locking position and rotation of the cam 32, forcing the jaw on the slide against the cap, displaces the rod 22 outwards through the slide compressing springs 25, around the ends of the rod in the base 1, which prevents excessive force being applied to the cap.

Filed: 1933-01-18
Abstract: 398,084. Fluid-pressure brakes. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Compagnie des Freins Westinghouse ; 23, Rue d'Athenes, Paris.) Jan. 18, 1933, No. 1707. Convention date, Jan. 19, 1932. [Class 103 (i).] In fluid-pressure braking-apparatus comprising a triple or distributing valve 1 controlling the supply of pressure fluid to the brake cylinder through a valve device 7 which permits at first a free and then a restricted supply to the cylinder and a separate graduated release valve device 6 to which the brake cylinder is connected by the triple valve 1 during release, the valve 7 is adapted to effect the final release of pressure fluid from the cylinder during the release operation. The triple valve 1 shown is of the usual type controlled by a piston 2 subject to train-pipe and auxiliary reservoir pressure and has combined therewith a graduated release valve 6 of the kind described in Specifications 343,929 and 346,831. During an application, pressure fluid is supplied from the reservoir connected at 4 through passages 12, valve 11, restricted passage 16, and passage 14 to the brake cylinder 5. When the brake cylinder pressure reaches a value sufficient to depress the piston 8 against the action of'spring 9 the valve 11 closes so that further supply is through the restricted passage 16 only. During release, when the brake cylinder pressure has fallen to a value sufficient to allow the piston 8 to return to the normal position shown, the cylinder exhausts directly through the passages 20, 21, 23 thus ensuring the complete release of the brakes. To avoid the necessity of providing an additional port in the seat of the slide valve 3 for the passage 20, this passage may be connected through a non-return valve to the passage 30 connecting the exhaust port of the triple valve to the release graduating valve 6.
