Title: Improvements in and relating to the formation of holes in printed circuit board assemblies
IPC: H05K3/00
Filed: 1965-11-08
Abstract: 1,119,860. Punching. INTERNATIONAL BUSINESS MACHINES CORP. 8 Nov., 1965 [23 Nov., 1964], No. 47226/65. Heading B3W. [Also in Divisions H1 and H2] A hole is formed in a single or multilayer printed circuit board assembly by projecting a free-flying pin therethrough at high velocity by pneumatic, hydraulic, or explosive means, or by magnetic impulse or an expanding fluid medium. Fig. 1 depicts a multilayer printed circuit board 20 located in a slot 23 between two plates 24, 25 having coaxial apertures 29, 30 on opposite sides of the board to enable a pin 31 to be projected therethrough by a ram 38 disposed in a hollow barrel 27; alternatively, the pin may form an extension of a free-flying ram. The pin may have a planar, convex, or concave leading face, and may be projected through and out of the board assembly to provide a hole therethrough for subsequent metallization. Alternatively, the pin may be arrested within the hole, as by a stop or by friction, with one or both ends protruding from the board to form a terminal; in this case the pin may be of square or rectangular section, to assist wire-wrapped connection thereto, or tubular to provide a socket for a mating plug, or cylindrical with one or more central longitudinal layers of insulation dividing it into two or more conductive partcylinders. The pin may be solder-coated, in which case it may be made of hard plastics material, glass, or ceramic. The speed of projection is preferably at least 300 in./sec., and may reach 4000 in./sec.

In a modification, for use in a muffle furnace, Fig. 4, heating elements 3 are mounted within the front frame 1, which has a closure plate 9 at its inner side, and apertures 12 in the front frame communicate with adjacent panels. The peripheral insulation 5 and the spaced foils 4 are mounted on the outer frame 1. The inner foil 4 is protected by gauze sheets 8 from the over pressure produced by a fan circulating air over the elements 3, and the apertures in the outer cover-plate 2 are closed by a foil.
Patent GB-970450-A (GB)
Title: Preparation of cyclic alcohols
IPC: C07C29/52
Filed: 1962-12-18
Abstract: Cyclic alcohols are prepared by mixing an aqueous solution of boric acid with a saturated cyclic hydrocarbon, evaporating water from this mixture so that boric acid separates out in a finely divided state in the hydrocarbon, oxidizing cyclic hydrocarbon in the presence of the boric acid by means of molecular or free oxygen so that an ester of the corresponding cyclic alcohol forms, and subsequently obtaining this alcohol from the ester by hydrolysis.  The boric acid may be obtained by hydrolysis of the ester formed in the oxidation of a previous quantity of saturated cyclic hydrocarbon in the presence of boric acid.  Before the boric acid solution is mixed with the hydrocarbon to be oxidized, acid by-products e.g. dicarboxylic acids are removed by basic anion exchanger and recovered. Examples are given of the formation of cyclohexanol and cyclohexanone from the oxidation of cyclohexane.  Other saturated cyclic hydrocarbons e.g. cyclo pentane, cyclo heptane, cyclo octane and cyclo dodecane may be similarly oxidized and the corresponding cyclic alcohols obtained.

Title: Process of making resilient elastometric floor coverings
Inventor: WISOTZKY REUBEN
IPC: D06N7/00
Filed: 1965-11-12
Abstract: A continuous process of making an elastomeric floor covering comprises the steps of coating with a viscous plastisol the surface of a continuously advancing solid sheet of elastomeric material said elastomeric material having a blowing agent distributed therein and being of firm consistency, heating the coated sheet as it advances until the plastisol coating is converted to a jell formation, molding ridges and valleys in the jelled plastisol while supported by the solid continuously advancing elastomeric sheet, and heating the resulting product to blow the elastomeric sheet uniting it to the fused plastisol and conforming it to the ridges and valleys thereof. The upper layer may be of wear-resistant material.  In the figures an elastomeric sheet material 10 having a blowing agent distributed therein, is coated with a plastisol by doctor blade 11 or by rolling or spraying.  The sheet passes through oven 13 to gell the plastisol. The coated material is fed to an embossing roller and then to blowing oven 20 to fuse the layer 12/mm and blow the under layer 10\sv.  At the same time a textile finish may be imparted to the exposed surface of the elastomeric sheet, by the material of the belt 16 which may be of textile.  The covering may be produced in solid colours and otherwise decorated before applying a translucent or transparent wear-resistant ply.  The covering may be of rubber or synthetic resin such as plasticized polyvinyl chloride or other vinyl resin or of polyethylene.
