Title: Metal carriers and the production thereof for film and the like making
IPC: G03D15/00
Filed: 1933-02-10
Abstract: The metal belt or band upon which film-forming solution is deposited, is made of hard metal such as iron or steel plated with a metal such as nickel which is not attacked by the fluids used in film manufacture, and the plating is subjected to rolling in order to convert its coarse crystalline structure into a fine structure which takes on a fine glassy smoothness when polished.  The iron or steel support is plated on both sides with nickel or on one side with nickel and on the other side with copper.  Film-forming solution may be deposited on both sides of the band if desired. If the copper-plated side is used it should be provided with a protective coating before depositing the film-forming solution upon it.  Instead of nickel, an alloy containing nickel as its chief component may be used.

Title: Improvements in and relating to controlling devices for alternating electric currentof variable frequency
IPC: H02K17/16
Filed: 1920-02-13
Abstract: 163,444. British Thomson - Houston Co., Ltd., and Taylor, H. W. Feb. 13,. 1920. Alternating - current induction machines. - The magnetic cores of apparatus for controlling alternating currents of variable frequency by the reaction of eddy currents, such for instance as used in the rotor circuits of induction motors for starting, are provided with a large surface exposed to the magnetizing action of the coils. This may be effected by radially slitting a solid core, Fig. 1<a>, or by forming the core with a stellate cross-section either solid or hollow, as in Fig. 1<c>, in which case a cut may be made at one place as shown. Longitudinal holes may be made through the core, these communicating with its outer surface by radial slits and assisting the ventilation in addition to providing an increased surface for eddy current action. The end members of a magnetic circuit containing such cores have an exposed surface area which is not less than that of the cores. Thus, the radially slit cores A of a three-limb inductance shown in cross-section in Fig. 2 are joined by end-members C of channel section having an exposed area per unit length not less than that of the limbs.

Patent GB-745632-A (GB)
Title: Improvements in or relating to process for refining hydrocarbon distillates
Inventor: KRAUSE JACK HARRY
IPC: C10G21/16
Filed: 1952-02-21
Abstract: Mercaptans are removed from sour hydrocarbon distillates with a minimum of colour degradation by contacting the distillate with about 5-200 per cent by volume of non-alkaline methanol which contains not more than about 10 volume per cent of water, separating the methanol and dissolved colour-forming bodies from the distillate, then treating the distillate with about 1-15 per cent by volume of an aqueous caustic alkali solution of 50-60 per cent concentration by weight, introducing an oxygen-containing gas into the caustic alkali-distillate mixture, maintaining the temperature at about 80-125 DEG F. and ensuring the presence in the mixture during treatment of 0.004-0.3 per cent of copper in the form of a copper compound which is active as an oxidation catalyst, and separating spent caustic alkali solution and associated reaction products from the treated distillate. Hydrocarbon distillates mentioned are heavy naphtha, kerosene, diesel oil, heater oil and furnace oil, which are derived from the distillation of crude oil or from cracking processes, either thermal or catalytic.  The caustic alkali may be caustic soda or caustic potash, while the oxygen-containing gas may be air or oxygen.  The copper can be added in the form of any compound which is somewhat soluble in the hot concentrated caustic alkali solution or which can be dispersed in the form of a water solution in the sour distillate before the caustic alkali solution is added.  The preferred copper compounds to be added are cupric chloride and cupric sulphate, and it is believed that the copper salt reacts with the caustic alkali to form colloidal copper oxide which is the active catalyst.  The sour distillate, before extraction with methanol, may be given a preliminary wash with a weak alkaline solution, for example a caustic soda solution, to remove hydrogen sulphide if this is present.  The methanol extraction removes colour-forming bodies which are believed to be alkyl phenols, while the treatment with caustic alkali which follows yields a spent alkali which contains cresylates.  Both the used methanol and the spent alkali may be regenerated for further use.  The treated distillate may be passed through granular or fibrous material (e.g. glasswool, sand or gravel) and then washed with water to remove traces of alkali.  Finally a small amount of a metal deactivator such as N, N1 disalicylidene -1, 2-diaminopropane may be added to the treated distillate. Specifications 728,057, 745,631 and 745,633 are referred to.

Abstract: 1,170,966. Discharging arrangement for cyclones. FISONS FERTILIZERS Ltd. 5 Jan., 1968 [1 Feb., 1967], No. 4904/67. Heading B2P. [Also in Division B8] A cyclone separator solids flow control valve 4 consists of a cylindrical metal shell 5 fitted inside with three rubber panels 6, 6', 6". Fig. 4 shows panel 6 before fixing and since the panel 6 is wider at the bottom than at the top it is deformed on fitting to the shell 5, point 18 being forced to the centre. In this way the three panels 6, 6', 6" form a seal as shown in Fig., 3. In operation a negative pressure is created within the cyclone separators (not shown) which serves to hold the panels 6, 6', 6" together until the weight of material overcomes the resilience of the rubber. An orifice is thereupon formed permitting the passage of large aggregates as well as fine material. Immediately after discharge the panels 6, 6', 6" again form a sealed unit thereby minimising ingress of air to the cyclone separators.
