Title: Catalytic conversion of hydrocarbons at subatmospheric pressure
IPC: C10G11/04
Filed: 1963-12-04
Abstract: A continuous process for the cracking of hydrocarbons, e.g. gas oil charge stocks with minimum formation of coke deposits, comprises contacting the hydrocarbon feedstock in the vapour phase at catalytic cracking temperature with a catalyst comprising a crystalline alumino-silicate having a cracking activity a  greater than 1.0, the partial pressure of the hydrocarbons in contact with the catalyst being less than one atmosphere and the catalyst being periodically regenerated to remove coke.  The cracking activity is preferably at least 10 and the reactor is maintained at below atmospheric pressure, the partial pressure of the hydrocarbon being reduced by vacuum or by an inert gas, e.g. carbon dioxide, nitrogen, propane, hydrogen sulphide, steam or mixtures thereof. Cracking preferably takes place at space velocities of 20 to 130 or 2 to 60 volumes of charge per hour per volume of catalyst and at 454 DEG  to 621 DEG  C., the catalyst being sufficiently active to overcome any deficiency of cracked product arising from reaction at reduced pressures compared to conventional cracking processes.  Tables 3 to 8 inclusive indicate the effects in the products obtained under varying reaction conditions.

Title: Arrangement for treating material with radiation from a radioactive ª‰-source
IPC: G21K5/02
Filed: 1964-11-27
Abstract: 1,083,464. Irradiation apparatus. OSTERREICHISCHE STUDIENGESELLSCHAFT FœR ATOMENERGIE G.m.b.H. Nov. 27, 1964 [Nov. 28, 1963; Aug. 17, 1964], No. 48428/64. Heading H5R. Various arrangements for the irradiation, by #-rays, of gases, liquids or solids, utilize thin plates or layers of radio-active #-emitting material substantially surrounding the material. In one embodiment (Figs. 1, 2, not shown), a tube of shielding material (1) is carried by a member (5) which has a layer (2) of #-emitting material or a protective layer (3). The outer shield (1) is necessary to absorb back-scattered electrons, bremsstrahlung radiation and any γ-radiation which may be produced. The effect of some of these radiations can increase the dose. Irradiation of varnishes on wires, is possible with the apparatus, or of grain, liquids or gases. Tubes having inserts in the forms of laminas or honey-combs may be used (Figs. 3, 4, not shown). Foils or rolled stock may be irradiated by passing them through two plates having radio-active surfaces (Fig. 6, not shown). For small amounts of liquid &c., rods with activated surfaces are rotated in a vessel (Fig. 5, not shown). Also described are irradiation cells for liquids each of which comprises top and bottom annular members (21) (Fig. 7, not shown), the side walls being made up by radio-active discs. A number of cells may be connected in a row, the radioactive discs (26) (Fig. 12, not shown), being held in position when the cells are bolted together. The discs may be of powdered radio-active material between metal foils or actually of solid material. Partition walls (25) within the cell, to guide the flow of liquid, may have radioactive layers. Other arrangements include cylindrical receptacles and arrangements for mixing or vibrating the matter to be irradiated. A requirement of all the arrangements is that the distance between radio-active walls should be less than the range of the #-radiation through the matter to be irradiated. Radioactive materials used may be strontium 90 and yttrium 90, promethium and tritium.

The concentration of carbon monoxide in exhaust gases is measured by determining the absorption by the gases of monochromatic infrared radiation from an electro-luminescent semiconductor source. Fig.2 shows a two-path system in which the measurement path comprises a pulsed electroluminescent or laser diode 23, supplied from unit 4, a through-flow chamber 14 for exhaust gases, and an infrared sensitive semi-conductor detector 5, feeding an amplifier 7, rectifier 8 and meter 9 or control means 10 for adjusting the carburretor of the engine producing the exhaust under examination. The diode 23 may be doped indium arsenide - indium antimonide body and emits radiation corresponding to a main or secondary line in the absorption spectrum of carbon monoxide. The detector 5 may be of indium antimonide, lead selenide or lead telluride. The other radiation path uses a similar detector 19 and similar circuitry and is used to maintain the wavelength of the radiation emitted by the source constant, by control of the temperature of the source, or the voltage supplied thereto. A semi-silvered mirror 18 splits the light from source 23 into two beams. In the simpler arrangement of Fig. 1 (not shown) only the measurement path is present.
