Title: Improved process of extracting phosphorus from its compounds by reduction
IPC: C01B25/02
Filed: 1926-11-20
Abstract: 275,145. Wittek, H. July 27,1926, [Convention date]. Phosphorus.-The extraction of phosphorus from its compounds other than heavy metal compounds is effected in conjunction with the nitrogenation of calcium, barium or other carbide. The phosphorus compound, such as calcium phosphate, may be placed in a separate furnace, in which case reduction is effected by the heat or the gases evolved in the nitrogenation or by the gases evolved in the heating of the carbide or the compound to be reduced may be mixed or stratified with the carbide, the reduction being effected by heating the mass while admitting nitrogen, or by heating the mass alone to effect reduction and then subsequently supplying nitrogen for the nitrogenation ; or cyanamide containing some free carbide may be heated with the compound to be reduced, so as to effect a purification of the cyanamide. Substances such as calcium fluoride or chloride or sodium chloride may be added to facilitate the nitrogenation. The cyanamide produced is in a form that does not require pulverizing, and is practically free from carbide. Specifications 274,803 and 275,144, [both in Class 1 (ii), Inorganic compounds, other than &c.], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes the production of other metalloids from their ores and compounds, mention being made of arsenic and antimony, and states that the metalloid may be obtained in the free state or in the form of a compound such as carbon disulphide. Instead of carbides, carbideforming mixtures may be employed. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electric switches for electromagnetic sound-producinghorns
IPC: H01H7/03
Filed: 1923-11-21
Abstract: 229,392. Spicer, W. J. Nov. 21, 1923. Press-button switches; momentary - contact switches.- A switch for closing the actuating circuit of an electromagnetically-operated soundproducing horn for use on motor vehicles comprises a contact-member moved by pneumatic means resulting from the operation manually as by a press-button of a piston or plunger the loose fit of which causes the air pressure to fall off after a short interval so that the contact-member again assumes the off position independently of the operating member. As shown applied to a pressbutton switch, the telescopic press-button carries a plunger k with a piston l working in the casing i. The movable contact-member in the form of a bent spring with a contact c rests in engagement with a leather diaphragm f. When the button is depressed, against the action of the spring n, the air pressure produced, acting through the diaphragm forces the contacts together, and, even if the button is held depressed, the contact-member resumes the off position after a short interval owing to the escape of air round the piston.

Title: Improvements in or relating to the production of oxygen-containing organic compoundsfrom carbon monoxide, hydrogen and olefins
IPC: C07C45/50
Filed: 1951-02-14
Abstract: Oxygenated compounds, particularly aldehydes, are prepared by generating a "cobalt carbonyl," which term includes a carbonyl hydride, continuously subjecting carbon monoxide, hydrogen, and an olefin in the presence thereof to an OXO synthesis, and treating at least part of the product for recovery of cobalt; the generation and recovery operations each being effected in one of at least three separate zones, each of which is used in a cyclic sequence for generation and recovery, each when employed for generation containing a solid cobalt compound or cobalt metal on a solid support and being supplied with a gas comprising carbon monoxide, and each when employed for cobalt recovery containing a solid support and being supplied with at least part of the reaction product under conditions whereby the cobalt is deposited thereon.  Preferably, each zone is used in sequence for catalyst generation, cobalt recovery, and treatment of recovered cobalt with hydrogen at 150-400 DEG C.  The cobalt carbonyl may be formed by the action of carbon monoxide at a partial pressure of 20-300 atm. and at 30-250 DEG C.  It may be prepared as a solution in, for example, hydrocarbons, alkanols or high boiling OXO products. Alternatively a gaseous product may be prepared and used as such or in solution.  The OXO synthesis is preferably operated at 100-180 DEG C. and at least 50 atm.  The weight of catalyst as cobalt may be .01-5 per cent. of the olefin. The product may be passed over a porous support, e.g. pumice, kieselguhr, silica gel or active charcoal, if desired with hydrogen, to recover the cobalt. For butyraldehyde, 150-200 DEG C. and 200-300 p.s.i. is suitable in this stage in absence of hydrogen.  If the aldehyde is to be converted to alcohol, more drastic conditions such as hydrogen pressures up to 200 atm. or more may be used.  With C2-C4 olefins, the aldehyde products may be flashed off and the residue subjected to cobalt recovery.  Cobalt oxide may be used as the support whereon cobalt is deposited, reduction of the oxide and hydrogen treatment of the cobalt then being effected in one operation: water gas feed is passed through the catalyst generator, temperature and amount of feed being varied to control the amount of cobalt taken in to the reactor.  When this falls too low, the generator is taken off stream and a second put on.  OXO product passes to high and low pressure separators and then to the recovery vessel where cobalt is deposited until 15-20 per cent. by weight of the support when the stream is diverted to another vessel, the first being purged with inert-gas and then used as a catalyst generator. Specifications 631,316, 702,192, 702,221 and 702,241 are referred to.

Title: Improvements in or relating to the purification of titanium tetrachloride and silicon tetrachloride
IPC: C01G23/02
Filed: 1951-12-18
Abstract: Titanium or silicon tetrafluorides are purified by bringing the tetrachloride as a vapour or liquid into contact with copper which has been activated by treatment with a lower alkyl (C1 to C4) alcohol, aldehyde or ketone, preferably acetone without coming into contact with air prior to use for contacting the tetrachloride and thereafter in the case of a liquid phase contact, distilling or in the case of a vapour phase contact, condensing the tetrachloride. The copper is preferably employed in the form of steel wool, turnings or drillings electrolytically or chemically coated with copper and the tetrachloride is preferably purified by refluxing before distilling.  Sharp inert solid particles may be included in the contacting vessel to abrade the surface of the copper and destroy the protective film formed thereon.  The copper coated steel wool may also be subjected to an intermittent magnetic field to provide agitation.  When the activity of the copper declines the coated steel wool may be treated with ammonium persulphate to strip off the copper.  The wool may then be recoated.
