Abstract: 1,145,492. Tapping casks, &c. bunghole bushes; venting casks. WADDINGTON & DUVAL (HOLDINGS) Ltd. 24 March, 1966 [1 April, 1965], No. 13915/65. Headings B8T and B8X. [Also in Division F2] To prevent temperature changes causing leakage between an integral seal 6 around the tubular plastics body 4 of a tap, &c. and a hole in the body 2 of a metal cask, &c. into which it is inserted, the inside of the tap body is provided with a ring 22 of metal having a similar coefficient of thermal expansion to the metal of the cask, &c. The ring 22 may be of the same metal as the cask, &c. and may seat in a groove within the tubular plastics body 4. As shown, the tap is of the push-pull type, having ports 16, 12 which in the aligned open position shown permit egress of liquid through a hole 10, air entering the cask, &c. 2 through the hole 10 and through aligned ports 18, 20. The tap is closed by pushing in its body so that the ports 12, 16, &c. are no longer aligned. In a modification, a metal ring (42), Fig. 2 (not shown), in the form of the skirt of an apertured pouring device, lies inside a plastics tubular body (24) in the plane of a seal (28) in a hole in a small metal cask (26). The pouring device has one hole (36) for the egress of liquid and another hole (38) for the ingress of air into the cask, &c. with a partition wall (40) between them. The pouring device is initially closed by a cap (30) having an easily-breakable connection (32) with the cask, &c. body (26).

Title: Process for fractionating normally gaseous mixtures
IPC: F25J3/02
Filed: 1966-03-29
Abstract: Normally gaseous hydrocarbon mixtures are separated into lighter and heavier fractions by a process which comprises passing the mixtures to a first fractionation zone controlled to produce a gaseous lighter fraction overhead and a desired heavier fraction also containing lighter components as bottom, recovering the overhead, and passing the bottom to a second fractionation zone controlled to separate the lighter components overhead and the desired heavier fraction as bottom which is recovered, the overhead from the second zone being substantially completely condensed and recycled part as reflux to the first zone and part as reflux to the second zone.  The part returned to the first zone is preferably cooled.  The feed mixture to the process is preferably partially liquefied to produce a volume of condensate slightly greater than the volume of the desired heavy fraction. The process is suitable for treating natural gas to remove pentanes, or both butanes and pentanes, as desired, or for recovering propane and propylene, or ethylene, from refinery gases, the particular separation required being accomplished by appropriate control of the temperatures in the fractionation zones.

Patent GB-234826-A (GB)
Title: Improvements in or relating to the treatment of sulphide ores or sulphidic metallurgical products
IPC: C22B7/02
Filed: 1925-05-28
Abstract: In a process for the conversion of sulphide ores or sulphidic metallurgical products containing volatilizable metals such as zinc, lead, tin, bismuth, arsenic, antimony, &c., into an oxidic "flue dust," the sulphides are decomposed in one operation at a high temperature, without previous roasting, in such a manner that the volatilization of the metals and the combination of the sulphur with the residue is simultaneously effected.  The oxidation of the metallic vapours may then be effected in the furnace or in a separate operation.  The raw ore &c. is mixed with a quantity of reducing material, such as coke, sufficient to maintain a reducing atmosphere in the material itself and at least a neutral atmosphere in the immediate surroundings, so that oxidation of the sulphur is avoided and heated to 1050-1400 DEG  C. in a suitable furnace.  To fix the sulphur, alkaline earth compounds, if not already present, are added to the charge, an excess being added preferably to decompose the sulphides formed. To avoid liquefaction of the charge in the volatilization zone, a refractory material such as alumina, silicic acid or limestone may be added.  After the expulsion of the volatile matter, the residue may be treated by a continuation of the process described above or otherwise.  If a large amount of barium sulphate is present in the ore treated it may be recovered as barium sulphide from the residue by lixiviation.

Abstract: 1355691 Cinematography EASTMAN KODAK CO 10 May 1971 [8 May 1970] 14042/71 Heading G2E A film storage device, designed to receive a reel R of film F having an aperture 6 in its end, includes a cartridge 2 between whose walls 9, 10 the reel is placed and having a barb 17 aligned with the film exit path from the cartridge 2 to engage the aperture 6. The cartridge 2 is able to fit within container 3 having a chamber 5. When the reel bearing cartridge 2 is so inserted in the chamber 5 a projection 24 on the wall 9 cooperates with surface 28 of wall 25 causing the wall 9 to flex inwardly. An identical projection (24') Fig. 5 (not shown) on wall 10 co-operates with surface 28' of wall 26 to cause flexing of the wall 10. The flexing of the walls 9, 10 prevents movement of the reel R when located in the container 3. This co-operation between the cartridge 2 and container 3 is the subject of Specification 1355692.

Patent GB-142164-A (GB)
Abstract: 142,164. Gray, J. G. Aug. 19, 1919. Steering.-Apparatus for use in steering aircraft consists of a coil or coils 2, Fig. 4, mounted on a gyroscopic stabilizer 16, and rotated in the earth's magnetic field, the resulting electro-motive force being indicated on a voltmeter 9 to show the position of the axis of spin, or of the frame 5, relatively to the magnetic meridian. The arrangement may be used for steering automatically by means of a motor operating a rudder and controlled by the voltmeter. When the coil is mounted horizontally, as shown, the vertical component of the earth's magnetic field may be neutralized by permanent magnets 10<1> attached vertically to the frame. When the axis of spin of the coil is arranged vertically, the horizontal component of the earth's field may be neutralized in one position of the aeroplane. &c., and strengthened in its reverse position, by horizontally placed magnets. The frame 5 may be arranged fore and aft, the reading on the voltmeter being then a minimum when the aeroplane &c. is moving in the line south to north, or the frame may be arranged at an angle with the fore and aft position so that when the aeroplane &c. is moving in a direction at that angle with the magnetic meridian, the reading on the voltmeter is a minimum. In the arrangement shown in Fig. 10, compensating arcuate magnets 10' are mounted adjustably on a sleeve 6 angularly movable on the frame 5 which is of cylindrical form. The magnets may be replaced by coils carrying currents. The coil may be driven by a propeller or from the spindle of the gyroscope 10. The slip rings 7 may be replaced bv commutators. The stabilizer is of the form described in Specification 130,697 [Class 97 (iii), Thermometers &c.] having stabilizer balls 15, and a plate 14 carried round by the spindle of the gyroscope.

Abstract: 360,885. Ovens. CARBORUNDUM CO., Ltd., Traff ord Park Road, Manchester. -(Assignees of Carborundum Co. ; Niagara Falls, New York, U.S.A.) May 8, 1930, No. 14233. Convention date, Oct. 7, 1929. Void [Published under Sect. 91 of the Acts]. [Classes 51 (i) and 51 (ii).] Returning combustion products.-Materials are heated by the repeated circulation of hot gases. In the oven shown in Fig. 1 combustion products are generated in combustion chambers 3 made of good heat-conducting and radiating material such as silicon carbide, and are continuously diluted by cooled gases withdrawn from the oven by a fan 7 and returned around the combustion chambers through flues 8. Surplus gases are withdrawn from the system by a fan 21. Perforated baffles 13 made of good heat-conducting material such as sheet metal direct the inflowing heating gases to the top of the charge 20. A modified form of combustion chamber 11, shown in Fig. 4, is divided by an horizontal partition into two superposed communicating compartments, in the lower of which combustion is effected, while the upper one has apertures 6 leading to the oven. The chamber is flanked by cool gas return flues 5 roofed by apertured plates 12. A similar construction with an undivided combustion chamber is also described. When the charge is to be heated without contact with combustion products the chamber 3 communicates with an exhaust flue 22, Fig. 5, by conduits 15 extending through the oven. The atmosphere of the oven is circulated through the charge and over the combustion chamber by a fan 71, and a change of atmosphere is effected at intervals by closing dampers 19 and opening dampers 17, 18.
