Filed: 1963-12-20
Abstract: 981,858. Coating wires by extrusion. HERCULES POWDER CO. Dec. 20,1963 [Dec. 24, 1962], No. 50483/63. Heading B5A. In a method of applying an orientated thermoplastic polymer coating to a wire, a wire 1 is drawn through a wire coating die 2 by take-up equipment 9 and thermoplastic polymer 3 is extruded around the wire 1 at a rate less than the linear velocity of the wire, the coated wire then being passed through a series of ball races 5 of gradually diminishing internal diameter to effect orientation of the polymer. Temperature conditioning of the polymer coating 3 may be accomplished by passing gas or liquid through chambers such as 4 and 7. A series of ball races 6 having the same internal diameter may be provided to " polish " the surface of the polymer coating. It is suggested that the ball races 5, 6 may be rotated about the axis of the wire as the coated wire is drawn through, to effect biaxial orientation of the polymer. Examples are given in which coatings of stereoregular polypropylene and poly-(3,3-bischloromethyl oxe. tane) are applied to single strands of copper and steel wire, respectively. The use of aluminium or tinned copper wire in single or multiple strands and of the polymers, polyethylene, polyethylene terephthalate, polyamides, polychlorotrifluoroethylene, polyvinyl chloride, and polyvinylidene chloride is suggested.

Title: Pneumatic transport system
IPC: B65G51/03
Filed: 1969-10-16
Abstract: 1,268,913. Pneumatic conveyers. INTERNATIONAL BUSINESS MACHINES CORP. 16 Oct., 1969 [13 Nov., 1968], No. 50864/69. Heading B8A. A system for advancing articles 11 through an enclosed duct 10, sequentially from one to another of a plurality of stations 18 to 22, comprises establishing an air pressure differential between adjacent stations, whereby an air flow is generated within the duct to convey the articles therealong on a cushion of air supplied through a permeable base 12 of the duct. The latter can be divided into segments by air-tight gates 32 to 35 and the end plates of the duct, each segment being associated with a valve controlled opening 18 to 21 and a pressure air inlet 40 to 43, apart from the downstream end segment which is associated with an opening 22 only. The pneumatic valves 24 to 27 for the openings 18 to 21, the pneumatic valves controlling the gates 32 to 35, and the supply of air to inlets 40 to 43 are automatically operated in sequence through a photo-electric device sensing the movement of the articles 11. In operation, in the condition shown in Fig. 1, segments are formed by the alternate gates 33, 35 and an article is positioned at the upstream end of each segment, the article adjacent opening 18 having been just inserted therethrough into the system and the article adjacent opening 22 being ready for removal from the system. With supply of pressure air at 40 and 42, the articles move along the duct from closed openings 18, 20 to open openings 19, 21, any overshoot of the articles being minimized by the increasing air pressure in the duct between the openings 19, 21 and the gates 33, 34, as generated by the air passing through the duct base 12. The other alternate gates 32, 34 are then used to form segments, and with similar use of the associated valved openings and air pressure supplies, the articles are further advanced along the duct. A photo-electric controlled vacuum pump may be associated with each opening to positively brake the article thereat. In an alternative arrangement the air pressure supply is dispensed with and the pressure differential along the duct created only by the air permeating through the duct base.
