Abstract: 1441934 Roller lock for web treatment chamber HOECHST AG 2 Oct 1973 [7 Oct 1972] 45984/73 Heading D1L A pressure lock for sealing the inlet to and/or the outlet from a pressurised web treatment chamber comprises first and second pairs of spaced apart nip rollers, the space between the pairs of rollers being maintained at a pressure intermediate the pressures upstream and downstream of the roller pairs. One or more additional pairs of nip rollers may be provided between the first and second pairs and the pressures in the additional spaces so formed maintained at pressures intermediate the pressures in adjacent spaces. In the preferred embodiment the roller lock is constructed to be used simultaneously for the inlet to and outlet from the pressure chamber 2, the web 1 to be treated being passed into the chamber in the direction indicated between the nips formed between a first set of rollers 3 and centrally located rollers 4 and out of the chamber 2 between the nips formed between a second set of rollers 3 and the central rollers 4. The chambers 6 formed between successive nips are maintained at pressures which are regulated by valves (not shown) so that the pressure exerted on the web gradually increases towards the pressure chamber 2 and correspondingly decreases as the web travels from the chamber 2. The central rollers 4 are preferably provided with a resilient elastic covering 9 and the rollers 3 made of metal. The rollers 3 are urged towards the rollers 4 by fluid filled plastics cups or tubes 5, the pressure in which is regulated by applying pressure (pneumatic or hydraulic) via feed pipes 7. Frictional resistance between the rollers 3 and the tubes 5 is reduced by providing the tubes with a sliding covering 8 of e.g. polytetrafluoroethylene.

Title: Treating surfaces with perfluorocarbon polymers
IPC: B29C41/00
Filed: 1965-11-08
Abstract: 1,126,748. Coatings. C. W. FORESTEK. 8 Nov., 1965 [27 Nov., 1964: 22 July, 1965], No. 47195/65. Heading B2K. Perfluorocarbon polymer particles having an average particle size of less than 30 microns are incorporated into a surface which has a multiplicity of minute pores or fissures by disposing the particles in the pores or fissures in the surface at at least 50‹F below the temperature of the surface, fusion of the particles being avoided. The surface may be a metallic surface treated by say liquid-honing with grit or sand-blasting, depositing zinc phosphate, or plating with nickel, chromium and forming fissures in the plating by acid etching. or by anodic or cathodic electrolysis. Aluminium surfaces may be anodized or hard anodized. The metallic surface may inherently have the desired structure e.g. sintered or powdered metal materials or certain sprayed metal surfaces. The treated surface may be heated above at least 150‹F preferably 50 to 100‹F above the temperatures subjected to in use, and the perfluorocarbon resin deposited and forced into the fissures by say brushing on an aqueous dispersion, dusting with dry powder or air blasting with the dry powder. The particles can be at ambient temperature or below ambient e.g. -100‹F to -400‹F when applied. While still hot, the coated surface may be rubbed, burnished, scrubbed and then cooled, followed by scouring, polishing or glazing. The polymer may be polytetrafluoroethylene, polymonochlorotrifluoroethylene, or mixtures thereof, copolymers of tetrafluoroethylene with hexafluoropropylene, mixtures of polytetrafluoroethylene and oolytetrafluoropropylene. The surfaces may be re-treated if particles have become dislodged from the fissures. The treatment imparts low friction and low-adhesion to the surfaces. The surface of a metal mould may be treated e.g. tyre vulcanizing moulds. In Example 1 a multi-cavity matched die mould consisting of two steel plates for moulding rubber articles is cleaned, phosphatized and treated with polytetrafluoroethylene particles; in Example II steel core members for use in moulds for neoprene. articles are plated with electroless nickel, liquid-honed with grit and treated with polytetrafluoroethylene, in Example III steel plates are cleaned, hard chrome plated, treated by reversing current in a chromic acid electrolyte, and then treated with polytetrafluoroethylene.

Abstract: 1,126,790. Rolling threads. NATIONAL ACME CO. 21 Oct., 1966 [22 Oct., 1965], No. 47441/66. Heading B3M. A screw-threading implement includes threading members 21, each freely mounted on a shaft 23 having an eccentric portion 22, the shaft being rotated during threading to shift the member radially so that a tapered thread is produced on a workpiece. The shafts are provided with pinions 25 which mesh with a common gear 26 splined to a sleeve 30. Relative rotation between the sleeve and the shank 12 of the head thus produces rotation of the shafts. A transverse pin 42 extends through an elongated slot in the sleeve and includes, a cam follower section 49 which slides on a cam surface 45 (Fig. 3) positioned in the shank 12. The cam surface is in the form of an insert in the shank and can be substituted by a replacement insert with any suitable cam profile. During rolling, by means of rolls 21, a workpiece 53 together with the sleeve 30, move axially relative to the head causing the follower section 49 to slide over the cam surface, a spiral spring 34 urging the parts into contact. When the follower section reaches the end 47 of the cam surface the spring is free to rotate the pin 42 (so that a roller 69 on the end of the pin occupies the position 69a) in order to release the rolls from the workpiece. The roller 69, which cooperates with an aperture 65 in an annulus 60, permits the rolls to be reset to their initial position by means of a longitudinally movable yoke 63. A workpiece support 52 is screwed into a main mandrel 51, the relatives adjustment of these parts determining the point at which the rolls are released from the workpiece. The rolls may have annular threads and be skewed, or they may have helical threads. The head may be rotated relative to a workpiece or held stationary, and either the head or the workpiece can be fed longitudinally.

Abstract: 1,088,773. Detecting liquid interfaces electrically. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N. V. Nov. 25, 1964 [Nov. 27, 1963], No.47980/64. Heading G1N. To identify a particular point in a flowing liquid stream, e. g. an interface between two different hydrocarbon products flowing in a pipeline, a small quantity of liquid marker is injected into the stream to raise its electrical conductivity and the passage of the marker is detected by a conductivity cell downstream of the injector. The liquid marker may be a light hydrocarbon solution of a Ti, V, Cr, Mn, Fe, Co, or Ni salt of a carboxylic or sulphonic acid, preferably an alkylated salicylic acid, and may also contain a copolymer of a vinyl pyridine and alkyl esters of methacrylic acid to improve its stability. The liquid marker should have a specific gravity  substantially equal to that of the products flowing in the pipeline so that when it is injected at an interface between two different products it will diffuse into the products at the same rate as the products themselves interdiffuse at the interface thus affording the possibility of detecting the whole of the intermixed interface volume. The detector may be mounted in the main pipeline or in a small branch pipeline and may be connected to an input and balancing circuit, amplifier and recorder. The invention may be used for testing flow meters, Fig. 2 (not shown), or for automatically operating valves to separate the products and intermixed interface volume into separate storage tanks, Fig. 6 (not shown).

Abstract: 1,085,987. Ball and socket joints. TRW Inc. Dec. 4, 1964, No. 49465/64. Heading B2F. The bearing seat for a ball joint comprises a tubular body of elastomeric plastics material of low coefficient of friction and high elasticity (e.g. polyurethane or synthetic rubber with graphite or other solid lubricant in the pores thereof) having a part-spherical -inner surface 26 to engage a ball head, and an annular bottom surface 28 formed with an integral axially extending ridge 29 which is deformed by the closure cap of the joint housing when the joint is assembled, thus applying an axial force to locate the ball head securely.
