Title: Improvements relating to securing tubes of thermo-plastic material to metal ferrulesand the like
IPC: B29C65/04
Filed: 1942-07-02
Abstract: 560,088. Electric heating. JARRARD, L. H. P., and JARRARD, A. H., (representatives of Jarrard, W. J.), PAYNE, A. S. W., and BARDEN, J. H. July 2, 1942, Nos. 9171 and 10511. [Class 39 (iii)] [Also in Groups XXVIII and XXXVI] A tube or electric cable sheath of thermoplastic material is secured to a metallic ferrule which is a snug fit in or on the tube by applying pressure to the tube on the side remote from the ferrule by means of a metal gripper applying heat to soften the plastic in contact with the ferrule and removing the gripper after cooling. A split metal band may be provided between the gripping tool and the tube, the band being removed after the jointing operation or the band may be retained as part of the joint. The ferrule or the band may have slots or perforations into which the plastic material is forced by the pressure of the gripping tool. The heating may be effected by inserting into the ferrule the heating element of an electric soldering tool, the element being of stainless steel or copper coated with nickel or chromium. Heat may be applied by using the ferrule and band as electrodes and applying a high-frequency electric current so that the plastic is softened by heat due to its dielectric loss factor.

Title: Process for dimensionally stabilizing oriented films of crystalline vinylidene chloride-vinyl chloride copolymers
IPC: B05D7/04
Filed: 1950-04-14
Abstract: Oriented films of crystalline vinylidene chloride-vinyl chloride copolymers, in which the crystallites are oriented with their major axes parallel with the surfaces of the films, are dimensionally stabilized by heating them to a temperature between 125 DEG  and 10 DEG  C. below the softening point of the copolymer for 10-150 seconds while so securing the film as to permit 10-70 and preferably 30-50 per cent of the linear shrinkage in the direction of longitudinal and /or transverse restraint which the film would exhibit without restraint, cooling the film to at least 100 DEG  C. under sufficient tension to prevent further shrinkage, and finally releasing the film. The invention is particularly applicable to plasticized films containing (apart from plasticizer) about 88-93 per cent of vinylidene chloride and 7-12 per cent of vinyl chloride.  In an example a cut sheet of a film composed of a vinylidene chloride vinyl chloride copolymer plasticized with 7 per cent of its weight of di-(alpha-phenyl-ethyl) ether and having a softening point of 168 DEG C. is heated for 20 seconds in an oven at 140 DEG  C. while fastened in a frame permitting 50 per cent of the normal linear and transverse shrinkage to occur and is removed from the oven and cooled to room temperature while still in the frame.  The treated film shrinks less than 2 per cent when hung in an oven at 100 DEG  C. for 30 minutes. Specification 692,430 is referred to.

The strip may be formed from one solid strip or may be laminated from two strips 12, 16 as shown, Adhesive may be applied to the layer 16 or a band with adhesive on both sides may be used to attach the strip to the scale 10; such a band of sufficient thickness replacing the layer 16. The elements 18 may be secured in position by injecting an adhesive into a hole 22. For use with circular or square scales the strip may be formed as a plate made up of "concentric" rings or squares made readily detachable to allow the appropriate size to be selected.

Title: Improvements in and relating to the manufacture of concentrated acetic acid
IPC: C07C51/46
Filed: 1929-03-22
Abstract: 312,046. Distilleries des Deux-SÞvres. May 19, 1928, [Convention date]. Acetic acid is extracted from its aqueous solutions by solvents sparingly soluble in water and having a boiling point which may be close to or identical with that of acetic acid, the resultant extract being distilled in a continuous manner with an entraining liquid capable of forming a binary azeotropic mixture both with acetic acid and with water, the boiling point of the latter mixture being the lower. For example, 30 per cent acetic acid is extracted with butyl acetate. forming a solution containing 16 per cent acetic acid and 5.5 per cent water. This is introduced by a pipe 2 into a column 1 containing the requisite quantity of a petroleum fraction boiling between 99 and 101‹ C. A binary mixture of water and petroleum boiling at 80‹ C. passes up into a condenser 4 and thence to a separator 5 from which the petroleum layer is returned by a pipe 7. A binary mixture of acetic acid and petroleum boiling at 94‹ C. passes out at 8 through a condenser 9 to a separator 10, from which the petroleum layer is returned by a pipe 11. The lower layer of 90-99 per cent acetic acid is passed to a column 13 containing petroleum; the final traces of water are distilled off as petroleum-water mixture to a condenser 15 and a separator 16. Part of the water is returned by a pipe 18 to prevent the rise. of acetic acid in the column 13, and the remainder by a pipe 17 to a column 1. The petroleum is returned by pipes 19, 20 to columns 13, 1 respectively. Anhydrous acetic acid is withdrawn from pipe 14, and butyl acetate from the bottom of the column 1.

Abstract: 252,132. Dubilier Condenser Co. (1925), Ltd., (Assignees of Dubilier, W.). May 12, 1925, [Convention date]. Condensers.-In the form shown in Fig. 2 the stator 1 and rotor 2 comprise co-operating cylindrical ribs or projections 3, 5 respectively and the stator has radial ribs 7 secured to an insulating body 8. A metal punching 10 serves as a bearing for a shaft 11 on which is secured the hub 13 of the rotor the hub being connected to the plates by radial spokes 14. A projection 15 on the body 8 acts as a stop and carries the adjustable other bearing 17 of the shaft, and the plates 3, 5 may be moulded or cast into the arcshaped heads of the stator 1 and rotor 2. In Fig. 5 is shown a condenser wherein the heads are semi-circular end discs 1<1>, 2<1>, the former providing a bearing 10<1> for the shaft 11<1> which has a peripheral groove 21 to receive a locking- ring 22 adapted to engage a radially slitted concave spring disc 23. The rotor 2<1> has a flange 28 from which extend projections 29 engaging holes in insulating discs 30, 31 separated by a distance washer 34. The discs fit over a hub 32 on the shaft 11<1> and the ends of the shaft, hub 32 and projections 29 are riveted over to secure the whole together. A fine adjustment may be provided by a fibre wheel 45 engaging the milled edge 37 of the rotor when the stem 41 is depressed. The stator carries a piece of insulation 38 serving as a stop and carrying a contact strip 39 which is connected by a lead 40 with the rotor, the lead being secured under one of the rivets 29. In the form shown in Fig. 9, the radial arms 7<1> of the stator 1<a> are secured to an insulating head 8<1> and slotted to receive semi-cylindrical armatures 3<1> which may be made fast by being cast with the arms 7<1> or otherwise. The rotor 2<a> is cast in one with, or secured to, a shaft 49 which has a conical shoulder to receive a bushing 51 having in turn a conical shoulder to receive a washer 52. A spring disc 53 and lock nuts 54 are provided. In a modification, the stator and rotor heads and plates may be of the shape shown in Fig. 2. In Fig. 12, the rotor head has a bearing 27<b> filled with insulation 30<a> which carries a hub 32<1>, which form of bearing is also used for the rotor shown in Fig. 13, in which the plates 5 extend on both sides of the head and the stator is in two parts secured together by a cylindrical housing 56. An alternative form is shown in Fig. 14, in which the ribs of the two stators are staggered. Figs. 15 and 16 show the sets of plates each arranged in three parts and also the use of wedges 63 in two places for regulating the capacity range by varying the distance between the plates. These wedges may be used in the condenser shown in Fig. 1 between the bushing 10 and hub 13 and in similar places in the other modifications.
