Title: Thermocurable precondensates from polyepoxy compounds and aromatic amines and process for their manufacture
IPC: C08G59/50
Filed: 1964-11-09
Abstract: Phosphoric or phosphonic acid esters containing at least one aminoaryloxy group linked with phosphorus and at least one-NH2 group linked with an aryl radical are prepared by the process of Specification 1,027,059.  Compounds specified are: tris-(4-aminophenyl) phosphate; 4,41-diaminotriphenyl phosphate; 4-t-butyl-41-411-diaminotriphenyl phosphate; 3,31-diamino-311-N,N - dimethylaminotriphenyl phosphate; bis-(4-aminophenyl) biphenylyl phosphate; 3-ethylamino - 4 - methyl - 41,411 - diaminotriphenyl phosphate; bis-(4-aminophenyl) 2-naphthyl phosphate and bis-(4-aminophenyl) benzylphosphonate.  Bis - (4 - aminophenyl) 4 - hexahydrophthalimidophenyl phosphate is prepared by the reaction of a slight excess of tris-(4-aminophenyl) phosphate with hexahydrophthalic anhydride under nitrogen, water being removed by distillation.  Bis - {4 - (N - 2 - hydroxypropylamino) phenyl} 4-aminophenyl phosphate is prepared by reacting tris-(4-aminophyl) phosphate (1 mole) with propylene oxide (about 2 moles) under nitrogen.ALSO:Thermocurable, fusible solids are preconated densates of an epoxy compound having an epoxide equivalence greater than 1 and a phosphoric or phosphonic acid ester containing at least one aminoaryloxy or aminoaryl group linked to phosphorus, at least one primary amino group being linke to an aryl radical. The preferred aminoaryl phosphates and phosphonates have the formulae <FORM:1055358/C3/1> where R represents identical or different aryl radicals, R1 is H or an alkyl radical, Z is a divalent, aromatic, mononuclear or polynuclear radical, R2 is an aryl or aralkyl radical, n is 1, 2 or 3 and m is 1 or 2.  In those compounds containing more than 1 primary amino group per molecule up to all but 1 of those groups may be connected to amide, imide or N-hydroxyalkyl groups. The precondensates may be prepared in the presence of a filler. They may be dissolved in organic solvents or powdered for use in powder coating techniques.  The one-stage curing of polyepoxide by the phosphorus containing amines is also disclosed.  Precondensates from polyepoxides and phosphorus free aromatic diamines are disclosed in the comparative examples.ALSO:Iron sheets are coated by sprinkling with or dipping the heated sheet into a fluidized bed of a pulverulent precondensate of an epoxy resin and a phosphoric or phosphoric acid ester containing at least one ominoaryloxy or aminoaryl group linked with phosphorus, at least one -NM2 group being linked with an aryl radical.  The coatings are cured by heating.  The pulverulent precondensate may also be applied to a substrate by spraying, and an electrostatic field may be used.  In comparative examples a precondensate of an epoxy resin and 4,4'-diaminodiphenylmethane is used.  Fillers such as asbestos, glass fibres, mica, ground chalk, kaolin, quartz meal, metal powders and metal oxides may be present.

Title: Method and apparatus for receiving sound intended for stereophonic reproduction
IPC: H04R5/027
Filed: 1975-11-05
Abstract: Two artificial head stereo microphone pairs (1, 2) are set up separately from one another either in approximately the same plane at a distance from one another or virtually adjacent to one another or above one another. The recorded signals of the left-hand microphones (3, 5) of both pairs (1, 2) and the recorded signals of the right-hand microphones (4, 6) of both pairs (1, 2) are in each case fed to a mixing circuit (7 or 8) for the left-hand or right-hand channel. Through the use of two artificial head stereo microphone pairs (1 and 2), the creation of a gap is avoided in the reproduction of the recorded signals during the transmission, i.e. the sound does not suddenly jump from one loudspeaker to the other if, for example, a sound source moves from left to right or vice versa in front of the microphones (3, 4, 5, 6). <IMAGE>

Abstract: 1,185,100. Stencil duplicator. GESTETNER Ltd. 30 Aug., 1968 [13 Oct., 1967], No. 46850/67. Heading B6C. When a new stencil is applied to duplicator cylinder 11 it is secured at its leading edge by studs 2 and flap 4 and fed on to the cylinder 11 over rotatable bar 5, as the cylinder 11 is turned either under power or by hand. If the stencil has a backing sheet cover 6 may be closed during application, so that rib 8 contacts the backing sheet and, by forming the stencil and backing sheet combination 1 to follow a tortuous path, brakes it, and so smooths the stencil on to the cylinder 11. Preferably bar 5 is a cylindrical rod rotatably mounted in bearings in the frame of the duplicator. After the combination 1 of stencil and backing sheet has been applied to the cylinder 11 the backing sheet may be removed by tearing along a line of perforations. If desired, a proof copy may be made on the backing sheet prior to its removal.

Abstract: 1389315 Knitting machines; cams WIRKMASCHINENBAU KARL - MARXSTADT VEB 12 Oct 1972 47112/72 Heading D1C A cam system for a circular rib machine comprises a pin 3, rotatable in the cam block 1, and having in an axial slot 4 a cam-bearing element 5 slidable transversely to the pin axis. The orientation of the pin is determined by a peg 17 engaging a notched collar 15. The position of cam 6 is determined by locking element 7 which can be inserted in the slot either side of element 5 and locked against it by a screw 14. In one orientation of the pin, cam 6 acts as a raise cam. It can be slid across the pin into a recess 24 as shown in Figure 6 to act as a tuck cam. In its other transverse position it becomes a clearing cam. In a second orientation of the pin, cam 6 is horizontal and acts as a guard cam for inactive needles. In this position the collar engages a pin 18 so that the cam 6 is withdrawn slightly. A rotatable bolt (19 Figure 3 not shown) prevents axial displacement of one or more pins.

Abstract: 986,512. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 2, 1963 [Dec. 31, 1962], No. 47404/63. Heading H1K. In a method of doping a semi-conductor body by vapour diffusion, a semi-conductor compound substrate is heated in an atmosphere consisting essentially of the decomposition products or a compound whose cation is an element which acts as an acceptor, and whose anion is an element from the same periodic group as the anionic element of the substrate. The method of the invention is illustrated in the accompanying flow sheet, the polished semi-conductor crystal and the acceptor source material being placed in a quartz tube which is then evacuated and sealed. The acceptor source material decomposes, and since the anion of the compound is of the same group as the anion of the semiconductor compound it forms an atmosphere which prevents decomposition of the semiconductor compound. The semi-conductor material may be a III-V compound such as gallium arsenide, gallium antimonide, gallium phosphide, indium arsenide, or indium antimonide, a II-VI compound such as cadmium sulphide, cadmium selenide, or zinc selenide, or a III-V mixed crystal such as gallium arsenide phosphide, Ga(As x P( 1-x )). Zinc arsenide and cadmium arsenide are suitable acceptor materials for gallium arsenide, and copper selenide is a suitable acceptor material for zinc selenide. Zinc arsenide is also a suitable acceptor material for gallium phosphide.

Abstract: 1,247,164. Open chamber firearm. TRW Inc. 7 Oct., 1968 [6 Oct., 1967], No. 47509/68. Heading F3C. An open chamber breech mechanism for a firearm comprises a breech frame in which a cylinder 26 having at least one open chamber 40 is rotatably mounted. The cylinder 26 is rotated through an infeed position in which cased cartridges 56 are fed laterally into the chamber to a firing position and then to a cartridge ejector position. The cylinder 26 and frame define therebetween gas leakage interfaces about the open side of the firing chamber which interfaces are sealed by expansion of a fired cartridge case under the action of the propellent gases produced thereby. The curvature of the cylinder 26 and adjacent wall of the breech frame are of substantially the same curvature but the wall of the breech frame recedes from the cylinder at a small angle e.g. 0À025 radians in the direction of the cylinder rotation adjacent the firing position to relieve frictional forces acting between the expended cartridge case and the breech frame wall. With this scarfing the propellent gases through the cartridge case also produce a rotational force in the direction of rotation of the cylinder. Although the breech mechanism may be applied to fixed barrel weapons, propellent gas powered tools, such as slaughter guns, cable splicers, stud drivers and oil well perforators the particularly described embodiment comprises a four chamber cylinderfour barrel rotatable assembly firearm (Fig. 1, not shown).
