Filed: 1925-01-31
Abstract: 242,484. O'Dell, A. E., (Naamlooze Vennootschap Financieele Maatschappij Driebergen). Jan. 31, 1925. Mandrels.-The record-carrier in a phonograph or the like consists of a hollow cylindrical or slightly coned body 1 having narrow longitudinal slots 5 in its walls, to render them flexible, and having its surface barrel-shaped, i.e. the middle portion of the hollow' body being of somewhat larger diameter than either of the ends. This swelling-out may be obtained as follows. The hollow body is first machined to a size near its final dimensions. Then a shallow circumferential groove 4 is turned, near the middle, and a ring is tightly clamped round the groove so as to press the central part of the body 1 inwards to some extent. The surface of the body is next machined and polished so as to fit exactly the, record for which it is intended. Finally, the ring is removed. This results in the body 1 swelling centrally as shown, forming a mandrel which enables a record to be firmly held but to be readily removed, notwithstanding changes of temperature.

Patent GB-866560-A (GB)
Title: Method for maintaining catalytic activity
IPC: B01J8/00
Filed: 1959-01-28
Abstract: A catalytic method for treating a fluid hydrocarbon feedstock, in which a deelectronating agent reactive with metal catalyst components is liberated, and for inhibiting deelectronation of the catalyst, comprises continuously passing a stream of fluid electronating agent through the bed of catalyst and periodically introducing pulses of the feedstock into said stream, the period of time between pulses being sufficient to prevent mixing of components of each pulse with components of the next following pulse.  The method is used for the vapour phase hydrodesulphurization of a fluid petroleum feedstock (such as naphtha or gas oil) with a gamma-alumina supported metal catalyst (e.g. Ni), the said stream being of hydrogen; preferably the reaction zone has a length to diameter ratio of about 10, the stream of hydrogen flowing at about 100 cu. ft. per hr. per cu. ft. of catalyst, the said zone being maintained at 600-750 DEG F. and 200-600 p.s.i.g., the period of injection of feedstock lasting for about 5 seconds and the period between injection pulses lasting from 1 to 2 seconds.  The effluent of the hydrodesulphurization may be treated for recovery by hydrogen sulphide-free hydrogen and the hydrogen recycled.  Other catalytic metals mentioned are Mo, Fe and V.  Specification 847,768 is referred to.

A looselymounted or gravity-controlled valve 21 is associated with the inlet 15, and the arrangement is such that, with the casing in its normal position and with the oil level 11 below the inlet of the tube 17, vapour will be withdrawn through the two inlet openings 15, 16 and traverse the wire screen 10 in its passage to the outlet 13, but upon the casing becoming inverted the valve 21 will close the opening 15 and the flow of vapour permitted through the tube 17 and opening 16 only. In a modification the opening 16 is itself screened and communicates directly with the outlet 13, that is without the interposition of the screen 18. Means is also provided for returning to the casing 10 through a U-seal the separated oil which normally collects on the bottom head 19 of the screen 18, said means comprising ports 22b and 25a, in a hollowed portion 22a of the stem 22 of the valve 21 and in a cup portion 25 of a surrounding bearing 23, 24 respectively, as shown.
