Abstract: 1473807 Perfluorocarboxylic acids ASAHI GLASS CO Ltd 17 Dec 1975 51704/75 Heading C2C Perfluorocarboxylic acids are prepared by reacting at least one perfluoroalkyl olefin with ozone to produce a petfluoroalkyl ozonide and a perfluoroalkyl aldehyde and converting these intermediates to perfluorocarboxylic acid with an oxidizing agent. The production and the conversion of the ozonide are preferably performed in distinct steps. The reactant olefin preferably has the formula RfCH = CR<SP>1</SP>R<SP>2</SP> ,where Rf is a C 4-18  perfluoroalkyl group and R<SP>1</SP> and R<SP>2</SP>, same or different, are H or alkyl. The first oxidation stage is preferably conducted with O 3  containing O 2  or air, in the presence of an inert organicsolvent at 0-120‹ C. with an O 3  : olefin molar ratio of 1 : 1 to 3 : 1. In the second stage H 2 O 2  or a peracid may be employed as oxidizing agent with a molar ratio of agent to ozonide plus aldehyde of 1-10 at 0-150‹ C.

Title: Circuit assembly
IPC: H05K3/40
Filed: 1968-11-04
Abstract: 1,216,215. Welding by pressure. INTERNATIONAL BUSINESS MACHINES CORP. 4 Nov., 1968 [11 Dec., 1967], No. 52178/68. Heading B3R. [Also in Divisions H1 and H2] In a multilayer printed circuit assembly (see Division H1) electrical connections from one of the circuit layers 28 to 42 to one surface 44 of the assembly is accomplished by resistance welding a wire 54 to 62, passing through an aperture leading to the layer, to the layer. A plurality of conductive planes 28 to 42 interleaved with insulating layers 12 to 26 are arranged in a stack 10, the layers and planes being provided with aligned apertures in accordance with the connections to be made. An insertion-welding apparatus 200 is moved along X, Y co-ordinates by lead screws, Fig. 5 (not shown), until wire 210 from a spool 22 is positioned over a desired aperture and then a signal from programmer, 244 is sent on line 246 to energize motor 218 which drives associated cam 220 into engagement ment with cam follower 221 on lever 222. As cam 220 rotates towards its low point spring 227 pivots lever 222 about shaft 226 so that its head 224 moves downwards towards assembly 10 and the wire 210 is inserted into the desired aperture as the spool 212 rotates. At this time the welder 256 with short test circuitry 246 is continuously monitoring the resistance between wire 210 and the conductive planes to which no connection is desired. If a short is indicated the apparatus is stopped. When the wire 210 reaches the desired conductive plane and contact is made a stop feed signal is generated by circuitry 250 and passed to the programmer 244 to stop motor 218. A signal is then sent to welder circuitry 256 which generates a current pulse on line 258 leading to leaf springs 260 which contact wire 210. This current pulse completes a circuit through the wire 210 and the plane contacted by that wire so as to effect a weld between the wire 210 and the particular conductive plane. Motor 218 is re-energized and cam 220 continues to rotate to its high point moving head 224 upwards the wire 210 slipping therethrough. Cam 220 contacts a switch 262 and motor 218 is stopped after which a signal is sent on line 264 to energize motor 232 and rotate cam to move blade 230 laterally in a direction opposite to spring 236. Cutting edges 228, 230 are brought into contact with each other to sever the wire 210. When cam 234 reaches switch 266 at its high point motor 232 is deenergized. The apparatus 200 is then moved to a second aperture and the process repeated. The conductive planes may be made of copper and the wire gold-plated copper. If the wire is insulated the shearing operation removes a certain amount of insulation from the wire to bare the lower surface of the next segment of wire.

Title: Decorative sheet material
IPC: B32B27/00
Filed: 1966-11-22
Abstract: 1,133,888. Decorative laminate. ISERENORD. 22 Nov., 1966 [22 Nov., 1965], No. 52198/66. Heading B5N. Decorative sheet material has the appearance of tapestry and comprises a backing sheet having a coating of a thermoplastic polymer, and a fabric mesh bonded by adhesive to the coating on the backing sheet in such a way that the mesh remains visible. The material is made by coating the mesh and/or coated backing sheet with heat-activatable adhesive and bonding by heating the adhesive. The mesh may be woven, e.g. scrim, or obtained by combining warp and weft threads without weaving, and includes natural or artificial threads, e.g. of glass or metal. The threads may be simple or twisted, and may be flake, bouclÚ, or spot yarns. The threads may be dyed, the warp and weft threads may be of different materials, and the threads of the warp and/or weft may be irregularly spaced. The backing sheet may be polyvinyl chloride or a copolymer of vinyl chloride, and may be opaque, translucent, or transparent, e.g. transparent P.V.C. In the latter case a printed paper which may be resin-impregnated may be used as a further backing for the backing sheet. Other possible backing sheets are hardboard, leather, woven fabric, non-woven fabric, e.g. felt, or a transparent, translucent, or opaque film. Similar or different meshes may be bonded to both sides of the backing sheet, or similar or different backing sheets bonded to both sides of the mesh. In one particular example a flake yarn woven mesh is coated with P.V.C. plastisol and heated to gel the plastisol. The coated mesh is hot laminated, by calendering, to a P.V.C. coated paper. The sheet material may be used in lampshades or wall decorations.

The products have insecticidal and acaricidal properties and may be used in admixture with solid or liquid carriers or diluents, and optionally surface-active agents, e.g. in the form of powders, wettable powders, granules, suspensions, emulsions, or solutions. The potassium salt of O,O-dimethyl dithiophosphate is prepared by reacting O,O-dimethyl dithiophosphate in methanol with KOH. O,O - dimethyl - S - carboxymethyldithiophosphate is prepared by adding an aqueous solution of O,O-dimethyl dithiophosphate and an aqueous solution of KOH to a refluxing solution of monochloroacetic acid in chloroform and water. The product, after isolation, is converted to its acid chloride by reacting with oxalyl chloride at 60 C. in an anhydrous toluene medium. The acid chlorides may be obtained generally by reacting the acid with thionyl chloride or oxalyl chloride. Mixed anhydrides of the general formula (R<SP>1</SP>O) 2 P(S)SCH 2 CO.O.COR<SP>4</SP>, wherein R<SP>4</SP> is the acyl residue of a carboxylic acid, may be obtained by reacting R<SP>4</SP>COCl with an alkali metal salt of the acid (R<SP>1</SP>O) 2 P(S)SCH 2 COOH which may be prepared by reacting an alkali metal carbonate or hydroxide with the free acid. The mixed anhydrides may also be obtained by reacting the acid chloride R<SP>4</SP>COCl with the acid (R<SP>1</SP>O) 2 P(S)SCH 2 COOH in the presence of a tertiary base or by reacting the said acid with ketene to give the anhydride in which R<SP>4</SP> is CH 3 .
