Abstract: 276,658. Aktiebolaget Separator- Nobel, (Assignees of Aktiebolaget Separator). Aug. 24, 1926, [Convention date]. Paraffin wax, extracting. - Wax is separated from lubricating or other mineral oils by adding trichlorethylene or other liquid making the oil heavier than the wax, and passing the liquid through a centrifugal separator provided with a mechanical device. for transporting the separated lighter constituent to its outlet. The oil may previously be diluted with gasolene or other liquid, and may be cooled. Using' the centrifuge shown, the liquid fed through a pipe A flows from the lower end to the bowl rotated from a shaft J, and through the perforated discs B, E to the outlet F. The wax passes to the centre and is transported to the outlet H by a screw G rotated by a shaft I at a rate differing from that of tht bowl. The discs B, E may be less inclined at the inner than the outer parts to facilitate the flow of the wax to the centre. The screw G may be replaced by a movable piston, a series of conveyers on an endless chain, or any other mechanical conveyer.

Patent GB-593079-A (GB)
Title: Improvements in or relating to the manufacture of moulded articles from coal
IPC: C04B35/52
Filed: 1944-11-09
Abstract: The strength and hardness of articles moulded from coal as described in Specifications 561,498 or 561,546 are increased by firing them under non-oxidising conditions to a temperature above that at which they were moulded, e.g., to 700 DEG C. or above.  The firing which is carefully controlled may be conducted in an atmosphere of non-oxidising gas and if hydrogen or hydrogen containing gas is used the article is embedded in powdered graphite, coke or noncaking coal to prevent hydrogenation.  To produce an article of low porosity the firing is carried out in the presence of a gas or vapour of a carbon compound preferably a hydrocarbon, e.g., methane, propane, benzene, naphthalene, or anthracene, which decomposes to deposit carbon within the pores and which may provide the non-oxidising atmosphere or be in addition to it.  Alternatively after firing under non-oxidising conditions the article may be treated with a liquid which leaves a solid filling in the pores if necessary after suitable heat treatment, e.g., coal tar or solutions of metallic compounds, e.g., A12(No3)2 K2SiO3, H2 CrO3 or solutions of polymeric alkyl or aryl silicon oxides in organic solvents or molten sulphur.

Title: Method of dehydrating barium hydroxide hydrates
IPC: C01F11/02
Filed: 1959-06-26
Abstract: Barium hydroxide hydrates are dehydrated by heating them with an organic solvent or solvents which are inert to barium hydroxide.  The water of crystallisation may either be removed by azeotropic distillation, if the solvent and the water are immiscible, or by merely digesting if the solvent and the water are miscible.  In an example, barium hydroxide octahydrate is distilled with benzene, an azeotropic mixture of benzene and water coming over, and the hydroxide being dehydrated to the monohydrate.  By distilling the monohydrate with toluene the anhydrous hydroxide is obtained.  In another example, the octahydrate is converted to the monohydrate by digesting with dioxane.

Abstract: 677,389. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 11, 1950, No. 22311/50. Class 98 (i). [Also in Group XXXVII] In a protective arrangement for a rotating- anode type X-ray tube, the anode of which is rotated by a capacitor motor, operation of the tube is prevented when the anode is not being rotated, by means of a current-operated relay 10, Fig. 1, in series with the " phase " motor stator winding 6, a voltage-operated relay 8 connected across the " capacitor branch " motor stator winding 5 and a voltage-operated relay 9 connected between the " free " ends of the windings 5 and 6. When the motor is operating correctly the contacts 13, 11, 12 of the relays 8, 9, 10 are closed to complete a circuit between terminals 14, 15 to energize or permit the energizing of the tube. In the event of an open-circuit fault or a short-circuited stator winding one or more of the relays opens its contacts to interrupt, or prevent the application of, the high-tension supply to the tube as detailed in the Specification. In Fig. 2 the relays 8 and 10 close immediately power is applied to the motor, but relay 9 closes after a slight delay. The relay 8 is provided with additional contacts 32, which when relay 8 is energized, close to complete a circuit for a timing motor 29. The motor 29 rotates a cam 30 which initially closes contacts 33 to complete a holding circuit for the motor 29 and then after a slight delay closes contacts 23. Relay 9 is now energized and in addition to closing the contacts 11, closes contacts 24 to complete a holding circuit for itself and opens contacts 31, so that when after a further slight delay the cam 30 opens contacts 23, 33, the relay 9 remains energized and the motor 29 stops running. The relay 9 also opens contacts 20 to connect a choke 18 in series with the motor stator windings 5, 6, to reduce the voltage applied to them so that the capacitor motor may continue to run without over-heating.
