Title: Improvements in the synthesis of secondary and tertiary ethinyl-carbinols
IPC: C07C29/42
Filed: 1941-04-18
Abstract: Secondary and tertiary ethinyl carbinols are prepared by reaction of acetylenic hydrocarbons with aldehydes or ketones in presence of an alkali metal hydroxide and a solvent of the formula <FORM:0580921/IV/1> where R1 and R2 are alkyl groups, and R3, R4, R5 and R6 hydrogen atoms or alkyl groups. Solvents specified are ethylene glycol dibutyl or ethyl-butyl ether, and propylene glycol diethyl ether.  Potassium hydroxide may be added to an excess of the solvent while cooling to 5 DEG  C. or below, acetylene and the carbonyl compound then being added alternately in portions. Substituted acetylenes such as amyl or phenyl acetylene may be added mixed with the carbonyl compound. Ethylene glycol ethylbutyl ether is prepared by adding the monoethyl ether to a suspension of sodium in toluene, and then adding butyl bromide.  In examples: (1) potassium hydroxide is added to ethylene glycol ethyl butyl ether to produce a gelatinous complex, acetylene and acetone added alternately and, when reaction is complete, the product saturated with CO2, and worked up to give methyl butinol and tetramethyl butine diol; (2) phenyl acetylene and acetone in the same solvent are treated with potassium hydroxide yielding 1-phenyl-3-methyl-butinol-3.

Patent GB-806569-A (GB)
Title: Process for the preparation of aromatic carboxylic acids containing at least two carboxylic groups and the salts and other derivatives of said acids
Filed: 1957-05-07
Abstract: Salts of aromatic carboxylic acids containing at least two carboxyl groups are prepared by heating a polyvalent metal salt of an aromatic mono- or dicarboxylic acid to a temperature in the range 200-500 DEG C.  The salts may be converted by known methods to the free acid or other derivatives such as halides or esters. The preferred salts are those of the alkaline earth metals although the aluminium, zinc, cadmium, iron and other heavy metal salts may also be used.  Instead of the salts themselves mixtures such as the carboxylic acid anhydride and a metal oxide or carbonate may be used.  Typical starting acids are acids containing one or two carboxyl groups disposed on an aromatic ring system such as benzene, naphthalene, anthracene, diphenyl, terphenyl, diphenyl methane or benzophenone, the rings may also optionally bear halogen or alkyl substituents. The reaction may be carried out in the presence of catalysts, particularly the oxides and organic and inorganic acid salts of zinc, cadmium, mercury, lead and iron.  The catalyst may be present up to the extent of 15 per cent, preferably 0.5-5 per cent, by weight.  In order to minimize local overheating the reaction may be carried out in the presence of inert liquid or solid diluents and mechanical stirring and shaking or rotating autoclaves may be used with advantage.  As the presence of oxygen in the reaction vessel restricts yields the reaction is usually carried out in an inert atmosphere such as carbon dioxide, nitrogen or methane.  The yields are also improved if the reaction is carried out at an elevated pressure.  It is found that, unlike the reaction product obtained by heating alkali metal salts of aromatic carboxylic acids, this reaction produces a product where the predominant isomer contains carboxyl groups in the ortho relationship to one another.  In the examples 1-15 the magnesium, calcium, strontium or barium salts of benzoic, orthophthalic or isophthalic acids are heated under carbon dioxide pressure (except in Example 10 which is carried out at atmospheric pressure) in the presence of a cadmium fluoride or chloride, mercuric chloride, zinc benzoate or K2CdF2Cl2 double salt catalyst to give a reaction product containing predominantly orthophthalic acid together with smaller amounts of uncharged starting acid, terephthalic acid, isophthalic acid, hemimellitic acid and, in Example 12, benzene, obtained by a decarboxylation reaction.

Title: Improvements relating to the opacification of vitreous glazing compositions for application to aluminium and alloys thereof
IPC: C03C1/04
Filed: 1948-06-01
Abstract: 666,637. Opacification of vitreous glazes for application to aluminium. FRASER, R. P., and CIANCHI, A. L. May 23, 1949 [June 1, 1948], No. 14774/48. Class 56. The compositions described and claimed in Specifications 642,104 and 665,903 for the vitreous glazing of aluminium and its alloys are opacified by incorporating therein a molybdenum compound. The molybdenum compound is preferably embodied in the glazing composition not merely by mechanical dispersion but by precipitation. Thus the glazes may have added thereto 5 per cent by weight (NH 4 ) 2 MoO 4  and 1 per cent As 2 O 3 , the ingredients being well mixed, fused at 700-800‹ C., fritted, mixed with say 1 per cent enamellers' clay or bentonite or colloidal SiO 2  together with 5 per cent CaMoO 4 , or a mixture of 3 per cent CaMoO 4  and 2 per cent Na 2 MoO 4 , and if desired 1-3 per cent of ZrSiO 4  and the mixture ground to form a slip with water &c. The storing temperature is 450-600‹ C., and the percentage of opacifier is adjusted to ensure full precipitation of the molybdenum. A molybdenum oxide, or the molybdate of Pb, Ba, Ca, Na, K, or NH 4  may be used as the source of molybdenum, and a little Zr, Sn, or Ti compound may be added to enhance the opacifying action. Thus 1-15 per cent of the molybdenum compound with or without 0.5-3.0 per cent Zr (e.g. as silicate and/or oxide) may be added to the glazing composition. A yellowish colour may be obtained by adding say 0.25-2.0 per cent of an arsenic compound or 0.25-5.0 per cent of an antimony compound. The addition of molybdenum may be made before firing, or as a mill addition, or partly at each.

Title: Internal combustion engines
IPC: F02B1/04
Filed: 1974-04-03
Abstract: 1469295 Rotary positive-displacement fluid-machines R D LAMPARD 3 April 1974 [3 April 1973] 14820/74 Heading F1F In an I.C. engine a fixed member 14 with two diametral sliding vanes 52, 54 co-operates with a rotary inner housing 16, which is supported by bearings 20. Air is inducted through a gallery 62 and slots 64 in the vane 54 into a chamber 36 for said vane wherein said air is compressed before being transferred to a chamber 26 associated with the vane 52 through a port 71 and further ports 106, 108, 110 in a portion 28 of the housing 16. Periodically, the port 110 communicates with cavities 70, 72 and the ports 106, 108 communicate with cavities 68, 74, fuel being fed to each cavity through an injector element 104. The shape of each of the cavities 70, 72 and the arrangement of  grooves 180, 182 extending over the peripheral  surface of the member 14 from these cavities are such that the fuel and air in said cavities is rendered turbulent, the fuel therein being ignited by sparkplugs 94. As a radial seal 120, or 122, crosses a "cut-out" 96 combustion products in the adjacent cavity 70, or 72, flow through passages 184, 186, over the seal, and through another passage 196 into the cavity 68, or 74, the fuel in the latter being  thus ignited. After expansion the spent combustion products escape by way of a port 98, which may be controlled by a valve element (512), Fig. 19 (not shown). The air issuing from the port 108 scavenges the cavities 68, 74 and that issuing from the port 106 charges these cavities for combustion purposes. A fan assembly 140 is driven by the housing 16 through gears 126, 128, 130, 132 and serves to cool said housing and also to expel the exhaust gases through an outlet 160 and duct 176. The housing 16 may be fixed and the member 14 rotate, instead. In another embodiment, Fig. 17, an orbital piston member 402 co-operates with sliding vanes 407 in a casing 406 and defines therewith spaces 429, which communicate with corresponding cavities 421, 440 furnished with valves 422, 442 for air and exhaust gases, respectively. Fuel is injected into both of the cavities at 423, ignition in the cavity 421 being effected by a spark-plug 428 and in the other cavity by combustion products in the cavity 421 passing a seal 414 when the latter is in register with a portion 440a of said other cavity.
