Title: Organosilicon compounds
IPC: C08G77/00
Filed: 1957-05-22
Abstract: The invention comprises dioxolane-substituted organosilicon compounds which are (1) compounds of the general formula <FORM:0814788/IV (a)/1> where R and R1 are monovalent hydrocarbon radicals free from aliphatic unsaturation, R11 is methyl, ethyl or propyl, n is 0, 1, 2 or 3 and m is from 1 to 16; or (2) siloxanes of the unit formula <FORM:0814788/IV (a)/2> with or without units of the formula <FORM:0814788/IV (a)/3> where R3 is a monovalent hydrocarbon or halogenated hydrocarbon radical and y is 0, 1, 2 or 3.  The monomeric compounds are prepared by reacting a hydrogenosilane R13-nSi(OR)nH with a dioxolane <FORM:0814788/IV (a)/4> where z is 0 to 15, in the presence of platinum on finely divided charcoal or chloroplatinic acid as catalyst.  The siloxanes are prepared by (a) hydrolysis of the silanes which contain at least one (OR) group or cohydrolysis with other silanes; or (b) reacting a siloxane containing silicon-bonded hydrogen with the vinyl-substituted dioxolane referred to above in the presence of chloroplatinic acid.  The examples describe the preparation of (1) <FORM:0814788/IV (a)/5> (2), (3) and (4), compounds as in (1) where the Me(EtO)2 is replaced by PhEt(PrO), (EtO)3 and Me2Ph respectively; (5) <FORM:0814788/IV (a)/6> and the siloxane derived therefrom; (6) the disiloxane <FORM:0814788/IV (a)/7> (7) a siloxane derived from the compound (1); (8) a copolymer containing the units of the siloxane (7) with PhMeSiO, PhSiO1.5 and MeSiO1.5; (9) a siloxane derived from the silane (2) alone and with Cl2C6H3(Me)Si(OEt)2; (10 a trimethyl silyl end-blocked polysiloxane obtained from the silane (1) together with Me3SiOEt; (11) a copolymer obtained from the silane (3) together with Si(OEt)4, PhSi(OEt)3, MeSi(OEt)3 and PhMeSi(OEt)3; (12) the silane <FORM:0814788/IV (a)/8> The silanes are mostly liquids and are useful as lubricants, hydraulic fluids and impregnants for rendering materials water-repellent.  The polymers may be used as moulding compounds, impregnants and electrical insulation.  All the compounds may be converted to aldehydes by rupturing the dioxalane radical with acids to give products of the type ­SiCH2(CH2)mCHO.

Title: Improvements in the arrangement for the operation from a distance of an overload switch provided with a main current winding and a tension winding
IPC: H01H71/46
Filed: 1921-06-14
Abstract: 168,040. Krupp Akt.-Ges., r. Aug. 20, 1920, [Convention date]. Protective arrangements; electromagnetic and magnetic switches; indicators.-Relates to an overload switch with an overload and a tension winding, in an arrangement by which the switch is automatically re-closed when current ceases to flow in the tension winding, means being provided for operating the switch from a distance, for example, from the supply end of a motor feeder. A continuous-cuuent generator A supplies current to motors B with starters C through long-distance feeders B, B<1>. In the main circuit is a switch having contact e<1>, e<2> and an overload coil E, a spring normally holding the contacts together. A tension winding E<3> acts against the closing-spring, this winding being connected in series with a resistance F across the main switch. A further circuit through the coil E<3> passes through auxiliary contacts e<4>, e<5>, an auxiliary long-distance feeder G, and switches g<1>, g<2> to the opposite pole at the supply end. The contacts e<1>, e<4> are fixed, and the contacts e<2>, e<5> are secured together and movable by the electromagnetic action of the coils E. E<3> against the action of the closing-spring. Lamps J, Hare connected across the contacts e<4>, e<5> and the contacts of the normally open switch g<2> respectively. When in series the lamp J is fully lit and the lamp H dim, the full supply voltage being necessary to light the lamp H completely. Fig. 1 shows the normal switch positions with the starter C off, the lamp J being out and the lamp H fully lit. If the starter C is moved over, the circuit through the tension winding E<3> and resistance F is not sufficient to open the switch; but if excessive current flows, the overload winding E opens the switch, Fig. 2, and the circuit through the tension winding can now maintain it open until all the motor starters have been restored to the off position. When all the starters have been opened, a circuit through the windings E<3> and lamps J, H still maintains the switch open; and if this circuit be broken at g<1>, the switch automatically recloses, the lamp J dying out and the lamp H increasing in brightness. Any attempt to reclose the switch from the supply end before the motor starters were open, would be ineffective, owing to the maintaining-cirouit through the tension winding which was completed by these starters. The. switch may be opened from the supply end by momentarily depressing the switch g<2>, placing the full supply voltage across the winding E', the switch being maintained open by one or both circuits through the resistance F or the lamps H, J, and cannot re-close before both these circuits are interrupted.

Abstract: 903,749. Iron manufacture. KOPPERS CO. Inc. May 13, 1960 [Oct.28, 1959], No. 16980/60. Class 72. A method of heating and humidifying the blast for a blast furnace comprises blowing cold blast air through a preheater, heating the preheated blast by burning therein a gas containing a high proportion of hydrogen which forms water vapour in the blast, the remainder of the water vapour being supplied as steam after the blower and before the preheater, and delivering the heated and humidified blast to a blast furnace. As shown, cold air from a blower 42 is supplied to a stove 67 for preheating, steam in the required amount being supplied from a source 53. The preheated air then passes to a heating and humidifying chamber 55 where coke oven gas from a supply 58 is burned to heat the blast to the required temperature and to supply the remainder of the water vapour. Since the oxygen in the blast will be reduced by the combustion of the gas additional oxygen may be supplied from a source 62. Just more or just less than half the water vapour required may be supplied by combustion and control of the quantity supplied may be achieved by varying the temperature of the blast issuing from the preheater, a cooler blast requiring more gas to be burned and thereby adding more water vapour in the chamber 55. A recuperative type of preheater may be used.
