Title: The preparation of compounds containing a substituted decahydrodecaborate anion
IPC: C07F5/02
Filed: 1963-08-23
Abstract: The invention comprises linear polymers containing structural units of the formulae: <FORM:1016378/C3/1> wherein M is a cation, Z and Z1 are hydrogen or monovalent radicals, such as -CN, -COOH, -OH, halogen or hydrocarbon, a and b are integers determined by the valence of M, W is a divalent organic radical, e.g. a hydrocarbon radical, a polyalkylene ether or a fluorosubstituted alkylene radical.  Polymers may be obtained by reacting H2B10H10nH2O with a polymer containing an epoxy group or with an epoxide containing a polymer-forming group, followed by polymerization.  The polymer may be an addition polymer or a condensation polymer, such as a polyamide, polyester or polyurea.  Example describes the reaction of H2B10H10nH2O with (1) a glycidyl ether of hydroxymethyl-substituted polyethylene polymer, (ii) dicyclopentadiene dioxide to form a condensation polymer.ALSO:Compounds containing organo-substituted decahydrodecaborate anions are made by reacting H2B10H10.nH2O with an epoxide, preferably by adding liquid epoxide to a solution in 1,2-dimethoxyethane of a mixture of H2B10H10.nH2O and water in equal amounts by weight at a temperature of from 10 DEG  to 30 DEG  C.  By using appropriate quantities, compounds of the formula Ma[B10H10- y(OR)y]b ar obtained, where M is a cation, a and b are integers of 1-3, y is an integer, generally 1 to 4, and OR is the radical formed by ring opening of the epoxide. The product is recovered by precipitation as an insoluble salt, for example the cesium salt.  The groups joined to the epoxide ring may be hydrogen, aromatic, aliphatic, alicyclic, or heterocyclic groups or functional groups. Many suitable epoxides are specified.  M may be hydrogen, hydronium (H3O+), a metal, ammonium, hydrazonium, N-substituted ammonium, N-substituted hydrazonium, aryldiazonium, pyridinium, quinolinium, sulphonium, phosphonium, and metal ammines.  The N-substituted ammonium may be derived from pyridine, quinoline, morpholine or hexamethyleneimine, and [Co(NH2C2H4NH2)3]+2 is an example of a complex metal cation.  Examples describe the preparation of decaboryl bis-(dimethyl sulphide) from decaborane and dimethyl sulphide, and also compounds made from H2B10H10.nH2O and epichlorhydrin, styrene oxide, dicyclopentadiene dioxide, a glycidyl ester, 3,4-epoxy 2,5 - dihydrothiophene - 1,1 - dioxide, 3,4 - epoxy - 4 - methyl - 2 - pentanone, propylene oxide, dicyclopentadiene oxide carboxylic ester, dodecene oxide, 3,4-epoxycyclohexane carbonitrile, 1,2 - epoxy - 3 - phenoxypropane, dipentine monoxide, 1,2-epoxy-3(4-chlorophenoxy(propane, 1,2 - epoxy - 3 - methoxypropane, and phenylmethylglycidic ester.

Title: Production of paper pulp from wood chips and the like
IPC: D01G15/46
Filed: 1958-10-20
Abstract: 898,703. Preparing paper pulp. BAUER BROS. CO. Oct. 20, 1958 [Nov. 18, 1957], No. 33481/58. Class 96. In preparing paper pulp from wood chips or like vegetable material, the material is sheared into fibres and compressed to expel gases, e.g. air, and liquids. Pressure is then released, under conditions substantially excluding air, and the material is impregnated with a liquid. The material is fed, by a screw 44, into a hopper 45, which may have feed screws 46, directing the material, through an opening 14, into the barrel 13 of a screw press comprising a rotatable shaft 12, which carries helical flights or teeth 32, 33, 34, 35, 36 and conical enlargements 49, 53, 55, 59, and passes through the barrel. The end 17 of the barrel is closed and the other end 15 is connected to a duct 16 through which the pulped material is discharged. Collars 18, 19, 21, 22, 23 and 24 are located within the barrel. Between the end 17 and the collar 18, the collars 18 and 19, 21 and 22, 23 and 24 are cylindrical screens consisting, respectively, of bars 25, 26, 28, 31. Between the collars 19 and 21, 22 and 23 are tubes 27 and 29, constituting chambers 51 and 57, into which an impregnating liquid is fed through pipes 54 and 58. The shaft 12 may be driven by a motor 43 through the transmission illustrated. Material near the conical enlargements on the shaft is subjected to high pressures so that compacted plugs of material are formed to seal the chambers 51 and 57 from the air. Pressure on the material is released in these chambers. Liquids and gases expelled from the material escape through the cylindical screens, the bars of which may be provided with undulations and projections 47 to help in shearing the material and breaking up compacted plugs. In a modification of the process, no impregnating liquid is fed into the screw press and the pulped material is fed from it, without making appreciable contact with air, into the lower part of a bath of impregnating liquid, through and out of which the material is carried, to a discharge shoot, by a vertical screw conveyer. Excess liquid drains from the pulped material between the surface of the liquid and the discharge shoot.

Abstract: 653,524. Automatic exchange systems. STANDARD TELEPHONES AND CABLES, Ltd. Dec. 23, 1947, No. 33969. Convention date, Aug. 27, 1946. [Class 40 (iv)] In a two-stage group selector, first stage switches such as S11, S12 give access to numerical groups of second stage switches such as S21, S22, each of which has access to numerical groups of outlets, and different potentials are applied to the test wires of idle second stage switches to indicate which outlet groups contain idle outlets. As shown in Fig. 2, each first stage switch S1 has 3 groups of outlets denoted by the digits 1-4, 5-8 and 9-12 respectively, and each second stage switch S2 has 4 groups of outlets. Group relays 01 ... 04 are operated when there is an idle outlet in the corresponding group, with the result that test contacts t2 in the banks of the first stage switches are marked with negative, positive or alternating potential according to the condition of groups 1, 2, while test contacts t1 are similarly marked according to the condition of groups 3, 4. Upon seizure of the first stage switch S1, a common marker M1 is associated and a switch S therein is set by the incoming digit. The appropriate outlet group is marked over bank Sd relay 4 is connected over rec Rd2 and bank Sc to test wiper T2 or T1 so that the switch S1 hunts for an idle second stage switch S2 having an idle outlet in the wanted group. Relay 4 when operated grounds wipers T1, T2 to busy the seized switch S2 and connects up 5, which completes a circuit over the a wire for line relay 7 of the switch S2. A common marker M2 is taken into use and relays 9, 10, 11 therein are selectively operated over the b wire which at bank Sa of the switch S is either disconnected or connected to ground through resistances R3, R4 or R4 or directly. The appropriate outlet is thus marked and the switch S2 moves to an idle one. Test relay 12 connects up switching relay 8 and relay 6 energizes over the a wire and connects up switching relay 2 of the switch S1, both markers being released. In a modification, Fig. 3 (not shown), the conditions of the outlet groups of S2 are indicated by alternating potentials of different frequencies on the test wire and the switch S selects corresponding filters. The marker controlling S2 may be set directly from a register earlier in the connection.
