Abstract: Beta-, gamma- or higher substituted cyanoalkyl silanes are prepared by reacting a silane of the formula H Si Rn X3-n, where R is hydrogen or an alkyl, cycloalkyl, aryl or alkaryl radical, X is halogen or an alkoxy or aroxy radical and n is 0, 1 or 2, with a mono-olefinic nitrile having 3 to 10 carbon atoms in the molecule, at a temperature between 40 DEG  and 350 DEG  C, in the presence of a catalyst which is an organo-phosphorus halide, a heterocyclic amine, a diaryl amine, an organo phosphonate, a dialkyl cyanamide or a hindered phenol.  The cyanoalkyl silanes are formed by the addition of the silyl radical to the olefinic carbon atom further removed from the cyano radical and the addition of the hydrogen atom to the olefinic carbon atom closer to the cyano radical.  Specified nitriles are acrylonitrile, methacrylonitrile, crotononitrile, allyl cyanide, 1-cyano-3-butene, 1-cyano-4-pentene and 1-cyano-1-hexene. Catalysts : (1) The organophosphorus halides include tri- and pentavalent phosphorus compounds, e.g., phenyl phosphorus dichloride, diphenyl phosphorus chloride, phenyl phosphorus tetrachloride and diphenyl phosphorus trichloride.  (2) The heterocyclic amines are six-membered ring compounds, the rings containing only carbon and nitrogen or only carbon, nitrogen and sulphur atoms which may have hydrogen, alkyl or aryl substituents ; and include also the compound 1-thiodiphenyl-5-amine.  Examples are 4-ethyl pyridine, gammapicoline and polyalkyl pyridines.  (3) The diaryl amines may include phenyl, tolyl, naphthyl, anthryl and phenanthryl radicals.  (4) The organo phosphonates have the formula :  <FORM:0847805/IV(a)/1> where R1, R11 and R111 are alkyl, cycloalkyl or aryl radicals ; specified compounds are diethyl ethane-, dibutyl butane- and diphenyl benzene phosphonates.  (5) The dialkyl cyanamides include dimethyl, diethyl, dipropyl and dibutyl cyanamides.

Title: Method for the continuous reflux reflux refining of metal
IPC: C22B19/32
Filed: 1975-09-24
Abstract: 1519999 Purifying metals COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION 24 Sept 1975 [30 Sept 1974] 39164/75 Heading C7D Metal is purified by introducing a massive ingot of impure metal into the relatively cool upper zone of a column consisting of a slurry of the metal crystals in liquid metal so that the chilling effect initially causes crystals to segregate and adhere to the ingot. Heat transfer soon causes incipient melting of the adherent crystals so that they fall through a continuous temperature gradient to a relatively hot zone at the lower end of the column. Pure metal is withdrawn from the lower end of the column and impure liquid, displaced by the downward movement of the crystals, is withdrawn from the upper end. Intrusive cooling elements may be used instead of the massive ingots.

Title: Improvements in or relating to butadiene polymers
IPC: C08F136/06
Filed: 1961-11-03
Abstract: Butadiene is polymerized using a catalyst comprising (A) an organometallic compound having the formula RnM where M is aluminium, gallium, indium, beryllium, mercury, zinc or cadmium and R is an alkyl, cycloalkyl, aryl, aralkyl or an alkaryl radical containing from 1 to 20 carbon atoms per molecule and n is equal to the valence of M, and (B) a member selected from the group consisting of (1) titanium tetraiodide, and when M is aluminium, (2) mixtures of titanium tetraiodide and titanium tetrachloride and (3) iodine and a titanium halide TiX4 where X is chlorine or bromine.  The butadiene is contacted with (A) to form an admixture therewith and then the admixture is contacted with incremental amounts of the (B) component. The term "incremental" covers either stepwise or continuous addition. Long lists of suitable catalyst components are given.  The polymerization is usually carried out in a diluent, lists of which are given.  In a batch process, the reaction mixture is inactivated by treating with an alcohol or water and the polymer is then separated and may be further purified.  In a continuous process the total effluent is pumped to a catalyst-in-activating zone where an alcohol, for example, is added.  If necessary a precipitating agent may then be added and the polymer separated from the diluent and alcohol which may be re-used after being fractionally distilled.  A polybutadiene having a cis-content of 85 to 98% or higher may be produced.  In the example the catalyst is triisobutyl aluminium, titanium tetraiodide and titanium tetrachloride and the solvent is toluene.

An air-cushion vehicle comprises a flexible skirting assembly through which air passes to form the cushion, said assembly being capable of conversion into a sealed buoyancy chamber, enabling the vehicle to operate as a catamaran displacement craft. A downward extension on each side of the rigid body 5 is formed with a duct 8, the walls of the extension carrying a flexible outer membrane 2, formed with curtainforming nozzles 9, and inner membranes 3, 4 secured respectively at their lower ends 12, 13 to the outer wall 2. The spaces between members 2, 3 and 4 communicate by way of ducts 15 and non-return valve 16 with a source of high pressure fluid and also by way of ducts 17 with a pressure regulating valve and deflation means 18. In operation, as an air-cushion vehicle the membrane 2 is inflated by air from duct 8, the membranes 3, 4 lying against the inner wall of membrane 2 so that air curtains may be discharged through nozzles 9 as shown in Fig. 4. To convert the vehicle into a catamaran displacement craft end walls (not shown) of the cushion area are collapsed and high-pressure fluid is admitted through ducts 15 to inflate membranes 3, 4 so that duct 8 and nozzles 9 are sealed-off and two buoyancy chambers 14 are formed as shown in Fig. 5.
