Title: Device for the manufacture of electric batteries comprising a plurality of cells in end to end relation
IPC: H01M6/44
Filed: 1934-10-24
Abstract: 443,609. Rotary and endless-belt conveyers. BRANDT, R., 17, Foscote Road, Hendon, London.-(Dansk - Engelsk Special- Maskin Kompagni Danebar; 38, Frederiksberggade, Copenhagen) Oct. 24, 1934, No. 30518. [Class 78 (i)] [See also Group XXXVI] A machine for making dry batteries of the kind comprising cells arranged end-to-end in a casing comprises means for introducing the cases into a conveyer and for placing the cells end-to-end in the cases and removing the filled cases. The filled cases may be transferred to a second conveyer which moves them into a vertical position. The cases a, Fig. 1, are arranged in a container 2 from which they are transferred by a ram to recesses in a revolving conveyer head 1. The cells bare introduced end-to-end into the cases by a ram 11 which pushes the cells through a mouth-piece 12 made in two parts urged together by springs. As the head 1 revolves it brings the filled case before a flanging device 13 after which the case is transferred to a conveyer 10 by means of a claw 16, Fig. 5. The claw forms a part of a lever 14 which is pivoted to a reciprocating slide 15. As the lever 14 moves forward it is guided by a pin 17 which slides on a rail 18. When the pin arrives at the end of the rail 18 the lever drops and the claw 16 engages the rear end of the case a. The slide 15 now moves backwards and the claw 16 pulls the case a out of its recess in the head 1 and transfers it to the conveyer 10. At the end of the movement the pin 17 rides up a sloping member 18<a> and is ready to remove the next case. The cases with their contained cells are now moved to a vertical position by the conveyer 10 and are taken below a spring plate 23, Fig. 11, which ensures that the tops of all the batteries lie in one plane to facilitate subsequent operations. The finished batteries are released from the conveyer at the end of its travel and fall into a collecting box.

Title: Process for isolating terminally carbofunctional organopolysiloxanes of a specified degree of polymerisation
IPC: C08G77/32
Filed: 1964-08-04
Abstract: In making siloxanes having terminal carbofunctional radicals by known processes, the siloxane mixtures so obtained are separated into individual polymers by adding to the mixture water and a water-miscible polar solvent which is capable of dissolving at least the lower polymers, separating the two phases and recovering the siloxane from at least one of the phases.  Solvents specified are ethanol, tetrahydrofuran and dioxan, and the functional radicals specified are halohydrocarbon, hydroxy ether or thioether, cyanoalkyl and carboxyalkyl. In one embodiment, the siloxane mixture is first dissolved in the solvent and a little water is then added; two phases are obtained and separated, the heavier phase containing water, a little solvent and the siloxane component of the greatest molecular wt.; this process can be repeated until the mixture has been separated into fractions of siloxanes of different molecular wts.  In another embodiment a mixture of solvent and water is added to the siloxane mixture and, beginning with the siloxane having the smallest molecular wt., individual siloxanes are extracted successively. If desired, coarser fractions or only one fraction may be extracted.  In a typical Example (1) 2 mls. of water were added to 150 g. of a chloromethyl-terminated dimethylpolysiloxane mixture dissolved in 300 g. of ethanol, and the resulting mixture was shaken and allowed to settle into two layers, the lower of which was separated and freed of volatiles to yield an oil; this process was repeated with the remaining solution to yield various fractions of decreasing molecular wts.

Abstract: Alkali metal borohydrides are produced by reacting an alkali metal hydride with a boron trihalide or an addition compound thereof in the presence of an amino borane catalyst of the formula RnB(NR1R11)3-n where R is hydrogen or an alkyl or an aryl radical, R1 is hydrogen or an aliphatic or aryl radical, R11 is an aliphatic or aryl radical, n is an integer from 0 to 2, and the catalyst is present in amounts of from 0,5 to 50% by weight of the alkali metal hydride.  The process is carried out in a high boiling (above 180 DEG  C.) inert suspension agent such as aliphatic and aromatic hydrocarbons, or inert oils such as tetra alkyl silanes, ethers, and polyethers, and at a temperature between 30 DEG  C. and the decomposition temperature of the alkali metal borohydride formed. The boron trihalide addition compounds may be those with di lower alkyl ethers, cyclic alkyl ethers, tri-lower alkyl amines, tertiary mixed lower alkyl aryl amines and pyridine, or it may be Na2O.4BF3.  The catalyst may be produced in situ by reacting an amine (R1R11NH) with an N-alkyl borazane selected from pyridine borane, N-tri-lower alkyl borazanes and N-di-lower alkyl borazanes; or R1R11NH with an alkali metal borohydride and a boron halide compound; or R1R11NH with a hydrocarbon substituted diborane of the formula (RnBH3-n)2 where n = 1 or 2.  A co-catalyst may be added to the reaction mixture, which is a tertiary alkyl or aryl amine or an alkyl ether capable of forming addition compounds with boron trihalides.  The co-catalyst may be present in amounts of 0,5 to 50% by weight of the alkali metal hydride.  Examples are given in which boron trifluoride-tetrahydrofuranate is reacted with sodium hydride in the presence of (C3H7)2BN(C4H9)2, <FORM:0905960/III/1> acid trisanilide, boric acid trisanilide with a cocatalyst triethylamine, N-triethylborazane with a co-catalyst dibutylamine. Numerous examples of R, R1 and R11 and also of the boron trihalide addition compounds are given.ALSO:Amino boranes of formula RnB(NR1R11)3,n where R represents hydrogen, alkyl or aryl group, R1 represents hydrogen, aliphatic or aryl group, R11 represents an aliphatic or aryl radical, n is 0, 1 or 2 are produced by reacting an amine R1R11NH with an N-alkyl borazane selected from pyridine borane, N-tri C1-C4 alkyl borazanes, N-di-C1-C4 alkyl borazanes. Alternatively the amine R1R11NH may be reacted with a mixture of alkali metal borohydride and boron trihalide or addition compound thereof, or it may be reacted with a hydrocarbon substituted diborane (RnBH3-n)2 where n=1 or 2.
