Title: Improvements in or relating to cracking oils
IPC: C10G9/36
Filed: 1934-02-19
Abstract: <PICT:0432736/III/1> <PICT:0432736/III/2> In processes for cracking oils of the kind in which the oil is cracked by direct contact with superheated gases or vapours, the temperature of the reaction chamber 1 is controlled by flowing the oil over a heat-exchanger 2 through which the materials to be superheated are passed on their way to the superheater 6.  In the modification shown in Fig. 2 the reaction chamber D is provided with end compartments F, G which communicate through tubes E passing through a cooling space 9.  Oil is pumped from a container 14 through a pipe 3 to the compartment G and a vaporizer B from which it circulates in part through the cooling space 9 and pipes 10, 11, the remainder flowing down the tubes E. The vapours formed are superheated in a coil C and then passed upwardly through the tubes E.  Part of the oil from the container 14 is passed through a preheating coil A to the vaporizer B.  The reaction products are withdrawn through a line 4.

Title: Uniform sizing of magnesium shapes
Inventor: DELONG HERBERT KENNETH
IPC: C23F1/22
Filed: 1962-02-13
Abstract: A magnesium or magnesium based alloy is uniformly reduced in size by immersion in an aqueous solution comprising nitric acid and at least 3% by weight of ammonium or an alkali or alkaline earth metal nitrate, a relative motion being maintained between the metal and the solution.  The solution preferably contains 0.7%-25% by weight of nitric acid and 10%-30% by weight of the nitrate, the solution temperature during treatment is up to 43  DEG C. Part of the magnesium article to be treated may be masked by coating with a resin such as polyvinyl chloride.  In an example an alloy containing 96% Mg, 3% Al and 1% Zn was degreased in alkali, water rinsed and then treated in the solution.
Patent GB-802521-A (GB)
Title: An improved method and apparatus for determining the combustible content of materials
Inventor: STARNES PETER EDWARD
IPC: G01N5/04
Filed: 1955-02-24
Abstract: Combustible contents of material such as furnace clinker and flue dust can be determined by taking two samples of the material, of known weight, and by means of a single current of air and/or hot gases moving at high velocity, drying and combusting the one sample while only drying the other sample, to determine the combustible content.  Two samples are weighed into receptacles 1 and 2, suction fan 10 is started and burner 21 ignited and swung into position over receptacle 1.  The hot combustion gases are drawn through the receptacle 1 through the <PICT:0802521/III/1> cooling tube 3 and into the second receptacle 2.  The length of the cooling tube 3 is designed so that the temperature of the gases on entering receptacle 2 should only dry and not combust the sample (approximately 110 DEG C.).  If the temperature of the gases as indicated by thermometer 5, rises above this value then cool air may be admitted into the cooling tube through inlet cock 6. If the temperature is too low then the rate of flow can be reduced by manipulation of the damper 12 on the fan outlet.  An alternative embodiment is described (in Figure not shown) for simultaneous testing of two batches of material.

Title: Improvements in or relating to electrically operated compression refrigeration apparatus
IPC: H05B1/02
Filed: 1954-03-04
Abstract: 784,509. Refrigerating. HERON, A. G. April 22, 1955 [March 4, 1954], No. 6329/54. Class 29 Defrosting a refrigerator evaporator by an electric heater DH is initiated by a timer T and is controlled by a switch P responsive to pressure in the evaporator and a thermostat ES responsive to the evaporator temperature. In Fig. 1, a circuit embodying a two pole time switch T is shown in which the compression motor circuit including a compression motor CM, a pressure switch LP, to safeguard against any faults in refrigerant circulation, and a thermostat CS, all in series, and the heater circuit including heater DH, pressure switch P and thermostat ES, all in series, are connected in parallel across the mains to poles 3 and 2 respectively of the switch T. In normal operation the switch is set at 3 and cycling of the compressor according to the temperature of the cold room is carried on. At a predetermined time the time switch sets at 2 and defrosting is initiated when the pressure inside the evaporator exceeds a certain limit the pressure switch P opens, the heater is cut off and the pressure allowed to drop until P closes again. The cycle continues until the timer switches back to position 3. Further control is obtained by the thermostat ES which opens when the temperature of the evaporator exceeds a certain value and cause defrosting to cease; this may be signalled by a lamp L indicating the necessity of manual resetting of the thermostat. An alternative arrangement utilizing a single pole switch is shown in Fig. 2, where closure of the time switch ST causes a solenoid operated switch 7, 8 normally closed, to cut in the heater circuit and cut out the compressor motor circuit. Reference has been directed by the Comptroller to Specification 694,763.

Abstract: 332,627. Siemens & Halske Akt.- Ges. Nov. 22, 1928, [Convention date]. Extracting rhenium. - In the extraction of rhenium from minerals such as columbite, gadolinite, or magnetic pyrites, the mineral is brought into solution for instance with hydrochloric or sulphuric acid and the rhenium then precipitated as sulphide, as with hydrogen sulphide, together with other sulphides so precipitated. The precipitate from a solution in hydrochloric acid of magnetic pyrites containing 0.0001 per cent rhenium may contain arsenic, molybdenum, and rhenium only. Further treatment may comprise repeated solution of the sulphide precipitate in nitric acid, precipitation of constituents other than rhenium with ammonium nitrate and phosphoric acid or a phosphate, and reprecipitation of sulphides by hydrogen sulphide. Finally when the rhenium is sufficiently concentrated it may be recovered as by fractional sublimation, the, sulphide concentrate being reduced by hydrogen and then gently heated in a current of oxygen, reduction, fractional volatilization, and reoxidation of the sublimates being repeated to separate the rhenium. It is stated that rhenium may be similarly removed by fractional sublimation of a mixture of chlorides. Mineral such as columbite containing as a main constituent an acid of an amphoteric metal may be first treated to render such acid) insoluble, as by fluxing with potassium bisulphate and extracting with water, with separation in the case of columbite of niobic acid. Specification 317,035 is referred to.

Abstract: 230,499. British Thomson-Houston Co., Ltd., (Assignees of Watson, H. L.). March 8, 1924, [Convention date]. Forming silica glass articles.-A process for producing elongated articles, such as tubes or rods, from silica consists in passing an electric current through a carbon rod which is surrounded by silica, as described in Specification 19574/02, and then, from the fused mass so produced, drawing plastic silica from a region adjacent to the heating-rod. The heating-rod 4 of graphite is mounted on a block 2 of refractory material, and is enclosed by a wall 1 of asbestos board or other refractory material. Comminuted silica 6, such as a good grade of sand or crushed quartz, is packed into the furnace, and when a heavy current is passed through the rod, a hollow slug 13 of fused silica, is formed. According to the invention, a, flanged tube 8, preferably of graphite, projects through the side of the furnace into the mass of silica, and is provided with a plug 11 which closes its inner end. A wire or bait 12, of tungsten, molybdenum or carbon, projects through the plug into contact with the fused silica. When the fusion of the silica is completed, the plug is drawn steadily outwards, and the portion of the silica adjacent to the heater is drawn into a tube or rod, as shown in Fig. 3. The rate of drawing is adjusted according to the desired dimensions of the tube or rod to be formed.
