Title: Improvements in refining hydrocarbons
Filed: 1925-03-09
Abstract: 249,309. Johnson, J. V., (Badische Anilin- & Soda-Fabrik). March 9, 1925. Mineral and tad oils, purifying &c.-Tars and mineral and tar oils are refined by distilling with non-superheated steam in presence of alkali hydroxide or alkaline-earth hydroxide. The products may be subsequently treated at an elevated temperature, with hydrogen, or gases containing free hydrogen, in presence of a finelydivided metal, preceded or not by treatment with fuller's earth or other adsorbent. Nickel, copper, iron, cobalt, platinum, or alloys thereof, with or without promotors or activators, are specified as suitable metals. Hydrogenation may or may not take place. The treatment with hydrogen may be at atmospheric, reduced, or increased pressure. In an example, 100 lb. of tar obtained by low-temperature carbonization of coal, lignite, or other carbonaceous material is mixed with 1 lb. of sodium hydroxide or slaked lime and distilled with steam. The distillate is passed into a tower maintained at 100-110‹ C. and packed with pumice-stone coated with reduced nickel carbonate or nickel aluminate silicate, hydrogen being passed in parallel or in counter current. Or the steam-distilled oil is agitated at 100-110‹ C. in presence of finelydivided metal while hydrogen is passed through. Prior proposals referred to include distillation of hydrocarbons with superheated steam in presence of alkali hydroxide or alkaline-earth hydroxide, and distillation of petroleum hydrocarbons with ordinary steam in presence of alkali and in particular a solution of commercial soda.

Title: Improvements in or relating to electron discharge devices
IPC: H01J9/40
Filed: 1945-03-14
Abstract: 589,580. High frequency discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd., and SMYTH, C. N. March 14, 1945, No. 6446. [Class 39 (i)] [Also in Group XXII] In making a vacuum tube two metal parts are assembled with juxtaposed surfaces parallel to the axis of the tube and with an intervening layer of a second metal readily diffusible into the metal of the parts at a temperature below the melting point of either metai, and a sleeve is placed over the parts, which are then heated so as to cause differential thermal expansion between the sleeve and the work parts when heated below about 200‹ C. so as to effect a vacuum-tight seal, the heating being continued to cause the intervening metal to diffuse into the parts to form a permanent vacuum-tight seal. The vacuum tube comprises an anode 1, a grid 2 supported in a grid disc 3 and a cathode 4 supported in a cathode disc 5, the discs 3 and 5 being sealed to glass parts 7 and a bulbous glass portion 8 being sealed to the disc 5. A spiral heater 9 is supported on wires 10, 11, welded to connectors 12, 13, sealed through the part 8 and a copper ring 14 with a feather edge is sealed to the glass portion 7. The copper anode 1 is joined to an inner tube 16 forming the inner conductor of a coaxial line and the discs 3, 5 are joined to the outer tubes 17 and 18, the anode-grid circuit being tuned by an annular piston 19 and the cathode-grid circuit by an annular piston 20. The ring 14 is sealed to the anode by electro-depositing a coating of gold on the ring and anode, placing a steel sleeve with a conical inner surface over the ring and heating for glass baking purposes. During the operation, the anode and ring expand more than the sleeve and are thus temporarily sealed to prevent hot gases from entering the tube when it is being evacuated through the part 8. Such sealing takes place before the temperature reaches 200‹ C., preferably between 50‹ and 100‹ C. During continued heating to 400‹ C., the gold eventually diffuses into the copper and renders permanent the vacuum-tight seal, after which the sleeve is removed. The sleeve may be initially of smaller diameter than the ring 14 and may be first heated to expand it and then fitted over the ring and shrunk thereon. The ring and anode may be of 50-50 nickel-iron alloy first coated with copper and gold, then placed between the parts. In this case the sleeve is kept cool and the anode is heated.

Title: Improvements relating to vacuum brake apparatus for railway and like vehicles
IPC: B60T13/46
Filed: 1930-02-27
Abstract: 348,745. Fluid - pressure brakes. GRESHAM, H. E. and GRESHAM, J. N., Ordsall Lane, Salford, Manchester. Feb. 27, 1930, No. 6504. [Class 103 (i).] Vacuum brake apparatus comprises two separate cylinders having the reservoir spaces above the pistons interconnected, one cylinder being directly connected to the train pipe and the other through a delay-action valve so that it is operated only on a predetermined fall of train pipe vacuum. The delayed cylinder is connected to the brake mechanism by means of a rack and toothed quadrant. The delay-action valve, Fig. 4, is connected by pipe 6 to the lower chamber of the delayed brake cylinder which is evacuated through a non-return valve 8 by the train pipe connected to a pipe 7. Air is only admitted from the train pipe on brake application to the pipe 6 when the valve 16 is raised by the diaphragms 11, 13, controlled by train pipe pressure below and the pressure in interconnected reservoir spaces of the two cylinders connected to pipe 3. Atmospheric pressure exists between the diaphragms which are connected to a collar 14 which is a free fit round the valve stem 15. A nut 15a on the valve stem engages the collar to lift the valve. Cocks 18, 19 can be operated by a single lever to connect the upper and lower chambers of the delayed cylinder to atmosphere to put this cylinder out of action. The rod r, Fig. 3, of the delayed piston is pivoted to a pawl s pivoted on arms y fixed to a lever u connected to the brake mechanism and carrying a toothed quadrant t. On brake application the brake cylinder directly connected to the train pipe first operates the brakes to take up slack and when the delay valve is open the piston-rod r rises and causes the pawl s to engage the quadrant t and assist in the operation. When the brakes are released the ends of the arms y engage a stop 2 and the continued movement of the rod r moves the pawl out of engagement with the quadrant. In one modification the brake cylinders act on different levers and in another modification on the same lever of the brake mechanism. The toothed quadrant is situated some distance from the pivot of the lever u to reduce the leverage exerted by the pawl.

Abstract: 971,153. Protective arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 6, 1961 [Feb. 29, 1960], No. 7089/60. Heading H2K. An arrangement for detecting out-of-step operation of a three-phase synchronous machine comprises a relay RCL energized through a rectifier Re by a vectorial combination of a first component corresponding to the current in one phase and a second component derived from the voltage between the other two phases. The first component is obtained from a main current transformer MCT and a variable-ratio auxiliary current transformer RTr and the second component may be obtained from a voltage transformer VTr and variable resistor RH. The current component may be limited by a non-linear resistor NLR. Under normal, leading power factor conditions, the relay RCL is sufficiently energized to maintain its contacts CO open, but should the machine fall out of step then the vectorial combination is reduced and the contacts CO close to energize a circuitbreaker trip coil TCL and/or an indicator Ic. A time delay relay having contacts TDCO prevents unwanted tripping or indication during an initial starting period. The contacts CO may control a circuit for restoring the in-step operation of the machine.
