Title: Process and apparatus for the preparation of thermoplastic polymeric composite sheets and films and thin thermoplastic polymeric film
IPC: B29C48/10
Filed: 1965-01-01
Abstract: 1,062,781. Producing composite laminated films. DOW CHEMICAL CO. Jan. 1, 1965 [Feb. 14, 1964; Sept. 29, 1964], No. 42/65. Heading B5B. Composite laminated or laminated films in tubular or in sheet form, which films each consist of three or more layers of organic thermoplastic polymeric materials, the composition of the materials in any two adjacent layers differing from one another, are produced by heating at least two such different materials to a temperature sufficiently high to render them plastic, forming them into tubular or sheetshaped streams, bringing the streams into contact with one another by superposition under laminar non-turbulent flat conditions so that the individual streams substantially retain their identity and extruding the resulting composite stream to form a tube or sheet of laminated film which is subsequently cooled to solidify it. At least one of the streams may be polyethylene and at least one of the streams may be polypropylene. The materials employed may have a relatively low adhesion for each other so that after extrusion and cooling the layers of the laminated film may be separated. The laminated films may be produced by means of an apparatus comprising a slot extrusion die having a body provided with a first internal passage adapted to receive a heat plasticized thermoplastic material, a first elongated extrusion slot communicating with the internal passage, a second passage terminating in a second extrusion slot, the first and second extrusion slots being parallel to each other and the second slot being disposed within the first internal passage of the die body and being in communication with the first slot. The apparatus may consist of two slot extrusion dies generally coaxially arranged to provide an inner die and an outer die so that the material forms a layer on both surfaces of the film or sheet extruded by the inner die. The position of the inner die may be adjustable with respect to the outer die and its outer surface may be provided with means so arranged that the flow of material to the slot of the outer die may be restricted to an extent depending on the position of the inner die.

Title: Improvements in the lining of iron and steel pipes, tubes and other hollow bodies
IPC: B05C7/04
Filed: 1927-01-01
Abstract: 282,981. Stewarts & Lloyds, Ltd., and Dewey, N. S. Jan. 1, 1927. Centrifugal machines.-In a machine for lining iron and steel pipes and other hollow bodies with a bituminous substance, the pipes are translated bodily by a conveyer after having been charged with the lining substance in liquid form and are at the same time spun about their axes to distribute and harden the substance. The conveyer comprises a number of parallel endless bands 7 with upstanding stoppers 21 which pass over two sets of sprocket-wheels 6, 3, the latter set being on a shaft 2 driven by a motor. The effective distance between the stoppers may be varied for treating different diameters of pipes by giving each alternate band 7 a lead over its neighbour. Spinning of the pipes is effected by means of a number of parallel chains 17 carrying friction belting which are disposed between the bands 7 and pass over two sets of sprocket-wheels 16, 15, the latter set being on a shaft 14 driven rapidly by a motor. Channel-shaped skids are provided for the bands 7 and chains 17. Between the feed end of the apparatus and the spinning bands are located a series of ramps 25 up which the pipes are forced for facility in charging, and a manually operated shaft 26 with arms 27 is provided for controlling the pipes when they are clear of the stoppers 21. A ramp at one end only may be employed if desired so that the pipes are tilted to facilitate charging, or alternatively the pipes may be raised hydraulically. The lining substance may be supplied by means of counterweighted ladles, The pipes are heated before reaching the ramps and are sprayed with water from apparatus 28 while passing over the spinning bands 17. The composition described in Specification 224,365, [Class 99 (ii), Pipes, tubes, &c.], may be employed as the lining substance.
