Title: New organic dyestuffs and process for their manufacture
IPC: C09B43/145
Filed: 1962-06-21
Abstract: In an example, (5), stabilized polyvinyl chloride, dioctyl phthalate and a dyestuff obtained by condensing thiophene-2:5-dicarboxylic acid chloride with two moles of 1-aminoanthraquinone are mixed and rolled to give a yellow foil.ALSO:The invention comprises azo dyes free from sulphonic acid groups and anthraquinonoid vat or pigment dyestuffs free from sulphonic acid groups in which both carbonyl groups of a thiophene dicarboxylic acid residue are joined to the amino groups of aromatic amines of the anthraquinone or azo series, the nitrogen atoms of the amino groups in said amines being directly attached to an aromatic nucleus.  The thiophene nucleus may or may not be further substituted. The dyes are made by heating a reactive derivative of a thiophene dicarboxylic acid or a tetrahydrodichlorothiophene dicarboxylic acid in a molar ratio of about 1 : 2 with an aromatic amine of the anthraquinone or azo series.  When the latter acid derivative is used, dehydrohalogenation to form a thiophene nucleus occurs.  Thiophene dicarboxylic acid derivatives specified are the anhydrides and chlorides of the 2 : 3-, 2 : 4-, 3 : 4- and 2 : 5-isomers, which may be substituted by methyl, phenyl, tolyl, naphthyl, hydroxy or methoxy groups or chlorine atoms, and cis- or trans-or a mixture of cis- and trans-tetrahydro-3 : 4-dichlorothiophene - 2 : 5 - dicarboxylic acid chloride.  Amines specified include, for example, a -(2-methyl, methoxy- or chloro-5-aminophenylazo) - a  - aceto - acet - (2 : 4 - dimethyl) - anilide, 1 - amino - 5 - benzoylamino-anthraquinone, 4 - amino - anthrapyrimidine, aminodibenzanthrone and 4 - aminoanthraquinone - 1 : 2 : 21 : 11 - benzacridone.  The dyes may be vat-dyes for cellulose fibres or pigments for plastic materials, lacquers or paints.

Title: Silarylene-silanes, silanols and cyclotrisiloxanes and the preparation of high-molecular weight polysiloxanes therefrom
IPC: C07F7/08
Filed: 1961-07-03
Abstract: The invention comprises silarylene silanes of the formula HR2SiR1SiR2H where R is a monovalent hydrocarbon radical free from aliphatic unsaturation and R1 is a p-phenylene, 4,41-diphenylene, 4,41-diphenylene ether, 4,41-dimethylene benzene or 4,410dimethylene-diphenyl ether radical, and cyclotrisiloxanes of the formula (R2SiR1SiR2O-)3, and also comprises the use of these compounds for obtaining the corresponding silane diols and higher polysiloxanes.  The silanes are prepared by reacting a dihalide XR1X, X being Cl or Br, with magnesium and a silane R2HSiX.  A conventional Grignard solvent is preferably used, and the system may be activated by a trace of iodine or a reactive halide.  The cyclic trisiloxanes are prepared by hydrolysing the silanes, preferably with aqueous ethanol and an alkali metal hydroxide catalyst, producing a siloxane of intermediate molecular weight which is thermally cracked in the presence of lithium hydroxide, and distilling off the cyclic compound.  The in its turn can be polymerized using the usual alkaline catalysts to obtain high molecular weight linear polymers. The silanes can also be converted to the corresponding alkoxy silanes by reaction with alcohol using metallic sodium as catalyst.  These alkoxy silanes can be hydrolysed with water, preferably in the presence of a hydroxide or pyridine, to produce the silane diols. These diols can also be prepared directly from the hydrogenosilanes by hydrolysing with strong alkali metal hydroxide solutions in aqueous alcohol followed by neutralization with an acid or acid salt. The silanols can be polymerized to high molecular weight, linear, orientable polymers by heating with alkali metal hydroxides or the amine salts of carboxylic acids as described in Specification 895,091.  Copolymers with the usual siloxanes may also be prepared leading to rubbers.  Uses: fibres, films, moulded articles.

Title: Flame monitoring apparatus and method
IPC: F23M11/04
Filed: 1972-05-22
Abstract: 1396384 Flame monitors CENTRAL ELECTRICITY GENERATING BOARD 18 May 1973 [22 May 1972] 24037/72 Heading F4T A selected flame in a multi-burner furnace is monitored photo-electrically along two lines of sight which intersect in the flame to produce two electrical signal outputs x, y, and the flame condition is established by determining the degree of correlation of the alternating components of x and y. Each photo-detector may comprise a tube 13 mounting a photo-sensor 12 and an optical image forming system such as a Newtonian or Cassegrain telescope or a collimating tube 15 and lens 14, the two tubes 13 being mounted in a single furnace wall aperture at an angle to each other greater than the acceptance angles of the optical systems which are kept clear by air bleeds through tubes 13. For pulverized coal or oil fuel silicon photo-voltaic sensors may be used, and for natural gas fuel infra-red responsive sensors, e.g. lead sulphide or indium antimonide photo-conductive elements, may be used. The outputs x and y are electronically processed in a correlator 16 in one of several exemplified ways. For example, outputs x, y pass through respective 20-1000 Hz band-pass filters (22), (23), Fig. 2 (not shown), to amplifiers (24), (25) giving outputs (x-x) and (y-y), where x, y are mean values of x, y, which outputs pass to a multiplier (26) and sealing amplifier (27) giving an output (x-x). (y-y), two rectifiers (29), (30) a multiplier (33) and sealing amplifier (34) giving an output |(x-x)|.|(y-y)|, and a divider (28) yielding the quotient (x-x).(y-y)/|(x-x)|.|(y-y)|. This quotient is smoothed by a low pass filter (35), having a 0À5 sec. time constant, to give an output which is fed to an indicator and/or recorder (37) and to a control (38) to shut-off fuel supply if no flame is detected. The final correlator output may have a first level indicative of no flame, a second level indicative of normal flame, and an intermediate level indicative of abnormal flame and arranged to operate an alarm or control device.
