Title: Improved process for the refining or cracking of hydrocarbons
IPC: C10G9/20
Filed: 1926-11-12
Abstract: 280,034. Collins, R. K. Nov. 12,1926. Hydrocarbons, cracking.-In cracking in the vapour phase, hydrocarbon vapours from a still are passed into a cylindrical casing D traversed by heating elements, consisting of electric resistances or of tubes 36, through which gases from the furnace of the still or from an independent furnace are passed. The vapours are passed by a pipe 80 into the lower end of the casing, and rise through perforated baffles 45, 46, which may be formed of nickel, to an outlet pipe 85. The heating of the tubes 36 and the flow of vapours are regulated so that the annular zones around neighbouring tubes in which the radiant heat is sufficient to effect cracking do not overlap, and the operations are carried out so as to obtain condensates which contain small quantities of suspended carbon. The casing D is supported on an insulating casing 52 'having flues 72 which communicate with the tubes 36 and pass through insulating plates 61, 64, and containing air spaces, the upper of which has vent openings 70. Steam may be passed into the casing D at the commencement of the distillation.

Abstract: 1,203,465. Crate stacking machine. DAWSON BROS. Ltd. 19 Sept., 1968 [23 June, 1967], No. 29067/67. Heading B8C. A crate stacking machine having pneumatic lifting means for the crates includes control means to increase the pressure of the pressure fluid supplied to the lifting means to increase the lifting force as the height of the stack increases so that the rate of lifting is substantially constant. The machine operates by lifting crates one by one by a crate height where it is held by catches, the next crate is positioned under the first and both are lifted by a crate height, and so on, until the desired stack height is reached. As shown in Fig. 1, ratchet segment 10 is indexed by pneumatic ram 12 at each lifting movement of the machine, by means of arm 14 which carries a spring-urged pawl 16. At the desired stack height, trip 18 is actuated and pawl 16 disengaged by ram 20 to allow the device to return to its initial position. An adjustable valve 22 regulating the pressure of the fluid supplied to the pneumatic cylinders of the lifting means is progressively adjusted as the ratchet segment is indexed and the stack height increased by an arm 24 bearing on cam 26 integral with ratchet segment 10. Control ram 28 is used to disengage the arm 24 from cam 26 to enable cam 26 to return to its initial position and allow the fluid supplied to the lifting rams to be reduced to its initial level.

Title: Improvements relating to gas discharge tubes
IPC: H01J17/06
Filed: 1947-11-07
Abstract: 652,100. Discharge apparatus. ELECTRONIC TUBES, Ltd., and SWIFT, J. D. Nov. 7, 1947, No. 29705. [Class 39 (i)] A method of manufacture of a glow discharge tube for voltage stabilization or for the production of a stable reference voltage comprises the step of passing between the two electrodes, after the tube has been given its gas filling and sealed off, a current greater than the working current, in order to produce positive ion bombardment of the cathode, and progressively decreasing the current to the working value. The cathode and preferably all the other metal parts exposed within the envelope may be of tantalum. In an example a 50 cycle alternating voltage of about 175 volts is applied for about 3 hours, resulting in a current density of 14 mA per cm.<SP>2</SP>; a direct voltage of about 175 volts is then applied and progressively decreased over a period of an hour until the working voltage of 100-105 volts is reached, at which the current density is 3-5 mA per cm.<SP>2</SP>. The tube may then be aged by being run at its normal working current for about 24 hours. Whilst A.C. is preferred for the initial high current, D.C. may be used instead. In the Figure, the electrodes 10, 11 and their support wires are of tantalum. The support wires 12 are welded to lead-in conductors 13 of chrome-iron and the junctions are covered with glass 15. The gas filling may be of helium and argon at a pressure between 0.5 and 40 mms. The method results in the envelope being coated with tantalum which acts as a getter to absorb any oxygen.
