Title: Improvements in or relating to the production of organometallic compounds
IPC: C07F7/12
Filed: 1966-03-10
Abstract: 1,132,037. Organometal, boron and phosphorus compounds. TH. GOLDSCHMIDT A.G. 10 March, 1966 [12 March, 1965], No. 10644/66. Headings C2C and C2J. [Also in Division C3] Methyl, aryl or aralkyl compounds of elements from Groups II B , III B , IV B  and V B  of the Periodic Table especially boron, aluminium, tin, phosphorus, zinc or mercury are prepared by reacting a halide or a methyl, aryl or aralkyl halide of that element, and the required methyl, aryl or aralkyl halide in the presence of a metal (e.g. Al, Mg, Zn, Sn, Li or mercury alloys of these) which serves as a halogen acceptor, the reaction being carried out in the melt of a non- oxidizing salt or salt mixture. The melt is usually a eutectic mixture of two metal halides, the halogen being the same as that of the reactants. The acceptor metal is either in solution in the melt or in a finely divided state. The acceptor metal is recovered from its halide, which is formed in the reaction, by electrolysis of the salt in which the acceptor metal is dissolved. The process may be run in batches or continuously. The basic apparatus for the continuous process consists of a cathode chamber equipped with a stirrer to circulate vapours through the melt and an inlet pipe for the organic halide and the inorganic halide (which may both be vaporized) and an anode chamber which contains an outlet for the liberated halogen and is separated from the cathode chamber by a porous diaphragm. The product is removed in the vapour phase from the cathode chamber. The examples relate to the preparation of (CH 3 ) 3 B, (CH 3 ) 2 PCl.AlCl 3 , or (CH 3 ) 2 PCl.2AlCl 3 . CH 3 AlCl 2 , (CH 3 ) 2 Zn, (CH 3 ) 2 - Hg and (CH 3 ) 3 SnCl.

Filed: 1973-03-07
Abstract: 1406737 Silicate foam BAYER AG 7 March 1973 [7 March 1972] 10963/73 Heading C1A [Also in Division C3] A process for the production of a foam comprises mixing an aqueous silicate solution with an expanding agent, converting the resulting mixture into a gel containing the expanding agent, and foaming the resultant gel by heating to a temperature of 90-220 C. Suitable aqueous inorganic silicate solutions are ammonium or alkali metal silicate solutions (e.g. water glass) and silica sols. containing alkali metal hydroxides or carbonates. The gelation may be achieved by concentrating the silicate solution by evaporating water or adding more silicate so that it solidifies to form a solid gel at low temperatures. Preferably the gelation is induced by adding a gelling agent. Numerous examples of gelling agents are provided, e.g. in specific examples: ethyl dimethyl phosphate, diethyl carbonate, isophthalic acid-dicarbonic acid ethylic ester anhydride, sodium silicofluoride, phosphorous thiochloride, dimethyl sulphate, chloroformic acid ethyl ester, benzoyl chloride, dimethyl maleate, sym. phthaloyl chloride, methyl hexahydrophthalic acid anhydride, ethyl chloroacetate, glycol diacetate, dimethyl carbamide chloride, tosyl chloride, dimethyl sulphoxide, vinyl acetate, glycerine triacetate, and ethyleneglycol dichloroformate. The composition may also contain fillers and diluents of which many examples are specified. The diluent may also serve as the expanding agent if sufficiently volatile. Other suitable expanding agents which decompose to liberate gases are disclosed. Heating may be carried out by applying high frequency microwaves, by infrared radiation, in a heating bath, by heating with steam or by hot air. Heating may be accompanied or followed by treatment with gases such as CO 2 , HCl, SO 2  or polymerizable monomers such as styrene, acrylic esters and acrylic acid. Foaming can be carried after pouring the gelling mixture into moulds, and webs, and woven fabrics may be foamed simultaneously with the silicate gels. The specific examples disclose foamable compositions comprising: (a) sodium silicate and 2À5-19% by weight asbestos fibres, based on the sodium silicate and asbestos; (b) sodium silicate, 5À2% by weight glass fibres and 15À8% by weight chalk; (c) sodium silicate, 1À2% by weight asbestos, 16À5% by weight chalk and 16À5% by weight polystyrene; (d) sodium silicate and 3À6% by weight polyester fibres; and (e) potassium silicate and 19À4% by weight asbestos fibres.

Title: Improvements in and relating to circular saw machines
IPC: B23D47/04
Filed: 1952-05-05
Abstract: 722,125. Sawing. CUNDEY, J. E., and CUNDEY, W. B. Aug. 5, 1953 [May 5, 1952; Sept. 16, 1952]. Nos. 11267/52 and 23185/52. Class 145. A circular saw machine has a circular saw blade 15a, Fig. 1, which is raised and lowered in synchronism with a gripper device 30 to hold the timber in place before the cutting action begins and an end stop 40 to locate the timber at the beginning of the cutting operation, the end stop being automatically withdrawn to allow the timber to drop at the end of the cutting operation. The saw is moved about a pivot 16 by a hydraulic ram 25 and is belt-driven from a shaft 11 which also drives a pump for the hydraulic apparatus through a belt 21. The shaft 11 is mounted on a frame 10, which may be on wheels for towing, and is driven by an internal combustion engine or other motor, the gripper 30 is operated by a spring-loaded hydraulic ram 31 and holds the timber in a rest formed by an inclined pair of rollers (not shown) while the stop 40 is adjustably secured to a sub-frame 53 pivotally connected by links 54 to the frame 10 and operated by a spring-loaded hydraulic ram 41. With the saw in its raised position, the pressure in the ram 25 is communicated through pipes 86, Fig. 2, and a pilot valve 87 to a cylinder 75 to hold a valve 85 against a pawl 88 held by a catch 91. Oil or other fluid under pressure from a pump 77 is thus able to traverse a closed circuit including pipes 76, 81, 83 and a tank 82. When the timber is brought into contact with the stop 40 the sub-frame 53 is displaced slightly in relation to the ram 41 to displace the catch 91 and allow the valve 85 to push the pawl into contact with a cam 93 the setting of which controls the speed of descent of the saw. The catch 91 may alternatively be released manually by a push rod 92, Fig. 1, and a lever 90. The valve in its new position allows fluid to exhaust from the ram 25 through a pipe 80, a port 85b and the pipe 81 while simultaneously pressure fluid flows from the pump 77 through lines 76, 95 to the rams 31 and 41. The ram 31 is loaded by a weaker spring than the ram 41 so that the gripper 30 engages the timber before the stop 40. When the saw has completed its descent under gravity it operates the pilot valve 87 to connect the pipe 86 to the pipe 81 so that a spring 99 displaces the valve 85 to the left in which position it connects the pipes 76 and 80 to liftthe saw and the pipes 95 and 81 to return the gripper and end stop to their original positions. A relief valve 98 prevents excessive pressure in the line 95 if the operation of the pilot valve 87 is delayed, and a valve 96, which allows oil to flow freely into the ram 41 but only slowly out of it again, ensures that the stop 40 is not restored to its original position until the cut timber has fallen from the saw. A number of end stops spaced at different distances from the saw may be provided, the required stop being released for displacement by a spring 63 to an operative position either by a hydraulic control mechanism or by a cable 61 and lever 60.
