Filed: 1930-01-20
Abstract: 335,865. Associated Electrical Industries, Ltd., (Assignees of Field, R. M.). Jan. 18, 1929, [Convention date]. Polyphase transformers.-A transformer system for interconnecting two power lines and controlling the voltage ratio and phase angle between them comprises two groups of main windings and a group of smaller auxiliary windings serially connected out of phase with one of the groups of main windings. Tappings on one of the main windings principally effect changes of ratio and tappings on the auxiliary windings principally effect changes in phase angle. An end of each winding of one of the main groups is preferably connected to the mid-point of the auxiliary winding to enable positive and negative phase changes to be obtained. Fig. 1 shows main windings 13, connected in star to a power system 6, and tapped main windings 11, connected to the mid-point of tapped auxiliary windings 18 in star. The windings 18 are smaller than the windings 11 and inductively related to a different phase so that a variable voltage component + 60‹ or -120‹ out of phase may be compounded with the variable voltage of windings 11. Specification 300,588 is referred to.

Patent GB-951489-A (GB)
Title: Improvements in or relating to silylated compounds
IPC: C08G59/32
Filed: 1962-01-19
Abstract: The invention comprises silylated polyepoxides characterized in that there are at least 3 epoxy radicals <FORM:0951489/C3/1> per molecule and that the Si atoms are attached to the epoxide moiety through Si-C bonds.  The organosilyl radicals can be <FORM:0951489/C3/2> in which R is any alkyl or alkenyl radical of less than 4 C atoms or any monocarboxy acyl radical of less than 4 C atoms, e.g. methyl, ethyl, propyl, allyl, formyl, acetyl or propionyl. The compounds can be made either (1) by reacting silanes of the formula (RO)3-n <FORM:0951489/C3/3> (n=0, 1 or 2) with polyepoxides containing C=C unsaturation, e.g. by heating at 50 DEG  to 150 DEG C. in the presence of colloidal Pt or an organic peroxide, or (2) by reacting silanes of the above formula except that H is replaced by an alkenyl radical, with unsaturated polyepoxides, e.g. in the presence of an organic peroxide.  The silane can graft to the epoxide as a monomer, or the alkenylsilane can first form a polymer (via alkenyl polymerization) which grafts to the epoxide. The polyepoxides used for the silylation have at least one C=C linkage and at least 3 epoxy radicals per molecule, and are best prepared by polymerizing conjugated olefins, such as butadiene or isoprene, and heating the resulting polymers with peracids, such as peracetic acid. In a typical example (1), trimethoxy silane and a dimethylphthalate solution of chloroplatinic acid were added to a toluene solution of an epoxidized polybutadiene, and the mixture was refluxed for 5 hours with subsequent removal of solvent and unreacted silane to yield a clear, viscous, oily product containing an average of 1 trimethoxy per 7 epoxy groups and per 5 unreacted C=C groups.  Uses: for sizing (as by dipping, spraying or brushing) siliceous materials, such as glass asbestos, silica, aluminium silicate and magnesium aluminium silicate, in the form of solid sheets, fibres or woven fabrics or in particulated form, the sized material being subsequently dried and heated for 1-10 minutes at 65 DEG  to 95 DEG C., prior to mixing with an organic moulding resin. Alternatively the silylated compounds can be mixed with the organic resins and thereafter add the siliceous material.  Organic resins specific are styrene, vinyl chloride, methylacrylate, methylmethacrylate, copolymers of epichlorohydrin and bis-(parahydroxyphenyl)-dimethylmethane, copolymers of maleic anhydride with propylene glycol and mixtures of polyester resins with vinylic resins. They can also be used to modify conventional epoxy resins for use as protective coatings and electrical varnishes, and can be used per se as laminating resins.

Abstract: Triarylmethane dyes are prepared by condensing in the known manner in non-alkaline media secondary or tertiary aromatic amines with aromatic aldehydes or with aromatic compounds containing two methyl groups at least two hydrogen atoms of each methyl group being substituted by halogen atoms, and converting the resulting leuco bases into the corresponding triarylmethane dyes by oxidation in the presence of acids.  Suitable amines are monalkylanilines, monohydroxyalkylanilines, dimethylaniline, diethylaniline, di-(oxyethyl)-aniline, N-oxyethyltetrahydroquinoline, N-dialkyl-m-aminophenols and their substitution products, and suitable aldehydes are iso- or terephthalaldehyde, diphenyl-p-p<1>-dialdehyde, o-chloroisophthalaldehyde.  Oxidation of the leuco bases may be effected by means of lead peroxide or pyrolusite in acid solution; if desired sulphonic acid groups may be introduced into the dyes. In examples terephthalaldehyde is condensed with dimethylaniline, diethylaniline and N-oxyethyltetrahydroquinoline in presence of zinc chloride, sulphuric and hydrochloric acids respectively and the resulting leuco bases oxidized by lead peroxide to dyes which give blue-black shades on cotton mordanted with tannic acid.

Cellulose, carboxylates. - Cellulosic materials, such as paper, cotton wool, or paper pulp, are acetylated in the presence of pyridine sulphuric anhydride. According to the conditions employed products can be obtained containing up to 56 per cent of acetyl group and soluble in different solvents. Some of the products, particularly the lower and middle members, are soluble in the usual solvents, such as acetone and chloroform, and yield viscous solutions, which can be made into threads, films, &c.

Abstract: 1,217,123. Friction Clutches. TWIN DISC Inc. 16 Jan., 1969 [19 Jan., 1968], No. 2606/69. Heading F2C. In an hydraulically operated multi-plate friction clutch wherein initial rapid clutch engagement is produced by pressure liquid supplied to a radially inner chamber 30 and thereafter full clutch engagement is produced by pressure build-up in a radially outer chamber 31 fed from the inner chamber 30 through an orifice 32, the engaging piston 10 carries an exhaust valve 40 which is closed when the pressure in the inner chamber 30 reaches a predetermined value. During initial clutch engagement the valve 40 permits air to flow into the outer chamber 31 through ducts 42, 47 and the air trapped in the outer chamber 31 when the valve 40 closes cushions clutch engagement. When the pressure supply to the inner chamber 30 is cut off for clutch disengagement the valve 40 opens to rapidly exhaust the outer chamber 31. The friction discs 8, 9 are separated by springs 48 during clutch disengagement. As shown in a double clutch a valve 24 transfers the exhaust fluid from the clutch being disengaged to the plates of the other clutch for cooling purposes.
