Title: Improvements in and relating to protective arrangements for systems of electric distribution
IPC: H02H3/00
Filed: 1930-04-11
Abstract: 351,136. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. -(Assignees of McLachlan, W. J. ; 15¢, Elm Street, Schenectady, New York, U.S.A.) April 11, 1930, No. 11573. Convention date, April 13, 1929. [Class 38 (v).] A protective arrangement for a feeder connecting an A.C. supply with a network is arranged to disconnect the feeder with a high value of reverse power flow under normal voltage conditions and with values of reverse power flow which vary with the feeder voltage, and comprises a power directional relay having an operating winding energized from the feeder and from a potential transformer which impresses on the operating winding a voltage which varies with the network voltage. Each feeder 3 is connected to the network 1 through a transformer 4 and circuit-breaker 5, the trip coil 12 of which is in series with contacts 22 of a power directional relay 15 having a coil 16 energized by the network voltage and a current coil 17 energized by a current transformer 19 in the feeder 3. The coil 17 is also energized through a transformer 25 by the feeder voltage so that a restraint against reverse-power operation is provided by the transformer 25 and the coil 16, such restraint diminishing with the drop in feeder voltage so that a smaller amount of reverse power is necessary to operate the relay 15 in such conditions. When a fault occurs in the feeder, the breaker 6 at the supply end opens due to the overload coil 9, and the reverse current reverses the torque of the relay 15, thus closing the contacts 22 and energizing the trip coil 12 to open the breaker 5. The contacts 22 are still maintained closed because the restraint is removed at the now open contacts 28 and the coil 17 is energized through a resister 24 across the breaker 5. When the breaker 6 is reclosed and the transformer 4 is re-energized, however, the relay torque reverses and closes contacts 21 so that the closing coil 11 is energized and recloses the breaker 5. In a modification (Fig. 2, not shown), protection is afforded to a 2-pole feeder by means of a relay 15 having a pair of current coils each energized from one pole, and a pair of transformers 25 being provided therefor, each also energized from one pole.

Title: Improvements in and relating to a method of and mechanism for mechanically extracting the inter-connecting threads between stitched books
IPC: B42B2/02
Filed: 1930-11-14
Abstract: 362,820. Book - stitching machines. POLLAK, J. E., 20, Holborn, London.-(Brehmer, Geb. ; Plagwitz, Leipsic, Germany.) Nov. 14, 1930, No. 11830/31. Divided on 362,132. [Class 112.] The interconnecting threads between two stitched books are mechanically extracted by a member which forces the foremost book away from the remainder of the book pad after manual or mechanical severance of the thread of the idle stitch made between the complete books according to the method described in Specification 362,863. The book pad a, Fig. 1, is shown stitched in the usual manner with a row of looped stitches, the thread e, forming part of the idle stitch between the completely stitched book c and the remainder of the book pad a. When the thread e is severed, either manually or by the method described in Specification 362,863, it will remain looped with the loop hand will hang in the loop g of the adjoining stitch. The thread e must therefore be extracted from the loop h before the book can be separated. To this end, a separator member 23, Fig. 8, is passed between the completely stitched book c and bookpad a. The book signatures are fed to the stitching device by the carrier 11, Fig. 5, and an idle stitch formed after the completion of each book. The threads e of the idle stitch are engaged by selector members 18 down which they travel to encounter arms 14 which the threads rock to trip the parts 14a out of engagement with stops 22. This enables a spring to urge a bar carrying the separator members 23 to the right during which movement the bar is guided by cam-slots to a lower position to enable the members 23 to enter between the finished books the rest of the book pad 15 force the book awav and withdraw the threads e cut by the knives 23a, Fig. 8, forming part of the members 23. The withdrawal of the threads e tighten the last loop g of the stitching. The thread extracting mechanism is restored to initial position by the cam 28, roller 27 and arm 26. In the case of books stitched by a staggered stitch, Fig. 11, and having a backing strip, the cutter is in advance of the separator member and the book first separated slightly from the pad for cutting, and then completely separated for extracting the thread. Specification 362,828 also is referred to.

Title: Process for the disproportionation of chlorohydrogenosilanes
Inventor: DUNOGUES JACQUES PAUL
IPC: C01B33/107
Filed: 1966-03-18
Abstract: Chlorohydrogenosilanes are disproportionated by heating them to a temperature below 150 DEG  C. in the presence of a tris-(tertiary amino) phosphine oxide.  The reaction is represented by the equation <FORM:1106721/C3/1> In the above formulae m and n are each 1, 2 or 3 and their sum is 4 or less, and R represents an alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl or aralkyl radical optionally substituted by groups which do not interfere with the disproportionation. The tris-(tertiary amine) phosphine oxide is a compound of the formula OP(NR1R2)3 in which R1 and R2 represent monovalent hydrocarbon radicals which may be substituted by one or more atoms or groups which do not interfere with, or take part in, the disproportionation. R1 and R2 may be the same or different and the individual groupings NR1R2 may be the same or different.  R1 and R2 may be joined to form a divalent radical.  The triaminophosphine oxide is used in an amount from 0.1 to 30% by weight based on the weight of the chlorohydrogenosilane. The mixture of the triaminophosphine oxide and the chlorohydrogenosilane is heated and the more volatile disproportionation product is distilled off.  When the operation is carried out continuously, the less volatile disproportionation product may be separated from the liquid remaining and the uncoverted chlorohydrogenosilane is recycled.  The reaction mixture may contain a diluent, e.g. an aromatic hydrocarbon. Examples are given of the disproportionation of methyldichlorosilane in the presence of tris-(dimethylamino) phosphine oxide or tris-(diethylamino) phosphine oxide and of butyl and phenyl dichlorosilanes in the presence of tris-(dimethylamino) phosphine oxide.ALSO:Chlorohydrogenosilanes are disproportionated to yield silicon tetrachloride or dichlorosilanes by heating them to a temperature below 150 DEG  C. in the presence of a tris-(tertiaryamino) phosphine oxide.  The tris-(tertiary amino) phosphine oxide is a compound of the formula OP(NR1R2)3 in which R1 and R2 represent monovalent hydrocarbon radicals which may be substituted by one or more atoms or groups which do not interfere with, or take part in, the disproportionation. R1 and R2 may be the same or different and the individual groupings NR1R2 may be the same or different.  R1 and R2 may be joined to form a divalent radical. The tris-(tertiary amino) phosphine oxide is used in an amount from 0.1 to 30% by weight based on the weight of the chlorohydrogenosilane.  The mixture of the tris-(tertiaryamino) phosphine oxide and the chlorohydrogenosilane is heated and the more volatile disproportionation product is distilled off.  The reaction mixture may contain a diluent, e.g. an aromatic hydrocarbon.  In Example 3, trichlorosilane and tris-(dimethylamino) phosphine oxide are heated together and the dichlorosilane produced is distilled off. In Example 6, trichlorosilane and trimorpholine phosphine oxide are heated together to give dichlorosilane and silicon tetrachloride.

Title: Improvements relating to the stripping of basic dyeings from polyacrylonitrile fibres, and the stripped fibres
IPC: D06P1/642
Filed: 1961-04-05
Abstract: Dyeing produced on polymeric and copolymeric acrylonitrile fibres, threads, wound spun yarn and textiles produced therefrom with basic dyestuffs, e.g. monoazo dyestuffs which contain one amino group in the molecule, methine and azomethine dyestuffs and basic di-and tri-phenyl methane, xanthene, azine, oxazine and thiazine dyestuffs, are stripped by treating them at a temperature of 85 DEG -105 DEG C. in an aqueous bath having an alkaline pH and containing basic nitrogen compounds which have a pKa value which is at least 6. Boiling, aqueous liquors containing 1-10 g/litre of the basic nitrogen compound and 1-10 g/litre of an electrolyte, e.g. sodium nitrate, sodium chloride, sodium sulphate, disodium hydrogen phosphate, trisodium phosphate, sodium acetate and sodium carbonate and the corresponding potassium salts, are preferably used for 30 minutes-2 hours.  The basic nitrogen compound may be ammonia or derivatives thereof in which the hydrogen is replaced by substituents which neither fundamentally alter the basic properties nor weaken them too much, e.g. hydroxyl, amino and organically substituted amino, alkyl and substituted alkyl such as hydroxyalkyl, aminoalkyl and polyalkylene-iminoalkyl groups (in these substituents two alkyl groups together or including an oxygen atom or an amino group can also form non-aromatic rings), aralkyl, cycloalkyl and amidyl groups, numerous examples of which are given.  The amino nitrogen atom of the basic nitrogen compound should not be directly substituted by acyl radicals derived from aliphatic or aromatic carboxylic or sulphonic acids or from carbonic acid or contain as sole direct substituents unsaturated ring systems of an aromatic character of the isocyclic and heterocyclic series although acylaminoalkyl substituents of basic amines and phenylhydrazine may be used.  The basic nitrogen compounds should not contain acid salt forming substituents e.g. carboxyl, sulphonic and phosphoric acid groups.  The fibres may subsequently be bleached with sodium hypochlorite, chlorite or dithranite or sodium or zinc formaldehyde sulphoxylate.
