Title: Improvements in or relating to electric protective systems
Inventor: NORTON DAVID JOHN
IPC: H02H7/045
Filed: 1953-12-09
Abstract: 767,189. Protective cut-out systems. GENERAL ELECTRIC CO., Ltd. Dec. 9, 1953, No. 3206755. Divided out of 767,188. Class 38(5) In a circulating-current protective system for power transformer in which a relay 27 is supplied with operating current over a rectifier 36, operation of the relay due to through-faults or magnetizing currents is prevented by a further rectifier or rectifiers connected in parallel with the relay and arranged to provide a low impedance shunt path to the relay when supplied with alternating current. The Figure shows the arrangement for one of the phases of a delta-star transformer, the primary winding 14 of a load bias transformer 21 being connected in one of the circulating-current lines and the primary winding 17 of a differential current transformer 25 being connected between the winding 14 and the star point of the line current transformers on the delta side of the transformer. One secondary winding 34 of the transformer 25 is connected to the rectifier 36 through a tuned circuit 37...39, and the other secondary winding 35 is connected to a rectifier 41 which in combination with a rectifier 22 and a resistor 40 is connected in shunt with the relay, the rectifier 22 being connected to the secondary winding 20 of the load bias transformer 21. The turns ratio of the transformer 25 and the tuning of the impedances 37...39 is such that the operating current supplied to the rectifier 36 is dependent on the fundamental frequency whilst that supplied to the rectifier 41 is dependent on the second harmonic. In the event of an internal fault in the transformer, the winding 34 supplies current through the rectifier 36 to operate the re, lay 27, but in the event of through-fault tne energizing of the rectifier 22 causes the operating current from the rectifier 36 to flow through the shunt circuit rather than through the relay and in the event of magnetizing currents the rectifier 41 has a similar effect, the relay being prevented from operating.

Abstract: 265,553. Newport Co., (Assignees of Oesch, J. B.). Feb. 6, 1926, [Convention date]. Tetrakisazo dyes are made by coupling a diazotized aminoazo body of the benzene series, containing one or two sulphonic groups and two to four methyl groups, with m-toluidine, rediazotizing and again coupling with m-toluidine, and rediazot.izing the trisazo dye thus formed and coupling with 1-phenyl-3-methyl-5-pyrazolone or a substitution product, particularly a sulphonic acid thereof. The products dye unmordanted cotton orange to brown shades of great fastness to light. In an example, sodium aminoazotoluene disulphonate used as the first component, and 1- p-sulphophenyl-3-methyl-5-pyrazolone (sodium salt) as end component. Strong reducing agents split up the dyestuff at the azo groups, yielding sodium 2-toluidine-5-sulphonate, sodium 2 : 5- diaminotoluene-3-sulphonate, methyl-p-phenylenediamine, and 1-p-sulphophenyl-3-methyl-4- amino-5-pyrazolone.

Title: Diorganopolysiloxane polymerisation
IPC: C08G77/00
Filed: 1960-09-23
Abstract: Siloxane polymers having from 1,95 to 2,7 organic radicals per Si atom are made by reacting, in the substantial absence of moisture and in a molecular ratio of from 2:1 to 1:2, (1) an organosilicon material containing at least one and an average of 1 to 2,05 Si-bonded OH groups with (2) an organosilicon material containing per molecule at least 2 and an average of 2 to 2,05 saturated aliphatic monoacyl radicals of 1 to 3 C atoms, the materials (1) and (2) being composed essentially of Si atoms having bonded thereto at least 2 radicals selected from monovalent hydrocarbon, halo-hydrocarbon and cyanoalkyl radicals, any remaining Si valencies in the compounds being satisfied with oxygen atoms.  Reactant (1) includes triorganosilanols and diorganosiloxanols having one or two terminal OH groups, and reactant (2) includes acyloxy silanes and diorganosiloxanes having two terminal acyloxy radicals.  The Si-bonded radicals may be alkyl, alkenyl, cycloaliphatic, aryl or any halogenated derivative thereof, or cyanoalkyl.  The reaction is effected merely by mixing the reactants, in the presence or absence of a solvent, e.g. toluene, xylene or methylisobutylketone, and with or without heat.  The reaction can be catalyzed by any non-ionic nitrogen base having a disssociation constant of at least 10-10, many examples of which are given.  The final polymers may be free from or contain terminal hydroxyl or acyloxy radicals depending upon the molar ratio of the reactants used.  In typical examples (Me=methyl); (1) equimolar amounts of <FORM:0899938/IV (a)/1> and a hydroxy-terminated dimethylpolysiloxane of 129 cs. viscosity (at 25 DEG C.) were mixed and heated at 110 DEG C. for 24 hours to yield a copolymer of 4,400 cs. viscosity; (9) ammonia gas was bubbled for several minutes through a mixture of a 9,740 cs. hydroxy-terminated dimethylpolysiloxane and dimethyldiacetoxysilane; the system was then closed and kept at 25 DEG C. for 90 hours to yield a copolymer of 48,400 cs. viscosity; and (15) vinylmethyldiacetoxysilane was added over a period of one-half hour to a mixture of a 5,000 cs. OH-terminated dimethylpolysiloxane and tetramethylguanidine to yield a copolymer of 500,000 cs. viscosity, the white insoluble tetramethylguanidinium acetate being removed by heating the product at 150 DEG C.  The copolymer of Example (13) was compounded with diatomaceous earth, a liquid (CH3)3SiO-terminated MeHSiO and dibutyltindilaurate and cured to a rubber at room temperature.

The valve is reversed by compression on the piston back stroke and by release on the forward stroke. The fluid supply 25 communicates with both sides of the valve by passages 19, 20 in the chest 3 which is held on the end of the cylinder by the screwed-on head 1. The valve-chest communicates with the cylinder ends by passages 18, 15. The auxiliary exhaust chamber 5, 5<1> communicate by ports 6, 6<1> with an annular recess 7 open through a passage 8 to the atmosphere. The hub ends 21, 21<1> controls grooves 11, 11<1> which communicate with the cylinder ends by conduits 9, 12 and with the atmosphere through the ends 5, 5<1>. The valve may have a central through passage, and one of the passages 6, 6<1> may be dispensed with. In a modification, the valve is of mushroom shape with the flat face forward ; the auxiliary exhaust is provided at the forward end only.
