Patent GB-108511-A (GB)
Title: Improved Cut-out for Electric Circuits.
IPC: H01H71/14
Filed: 1916-08-04
Abstract: 108,511. Marks, E. C. R., (Kuntziger, J., Chauvin, H., and Fontaine, F.). Aug. 4, 1916. Fusible cut-outs.-A replaceable fuse is formed of material having a high tensile strength, a limit of elasticity in the neighbourhood of the breaking load and slight elongation on rupture. In the construction of cut-out shown in Fig. 1 a length of such wire carries conical end pieces 10 and is held in tension in an insulating-tube 2, between the end-plate 4 slotted to receive it and a movable internal plate 7 similarly slotted, by a spring 8. The tube is held detachably within an insulating- block 3, the end-plate 4 constituting one terminal and the end-plate 5 to which the plate 7 is electrically connected, constituting the other terminal. When the current passing through the wire reaches a predetermined value the tensile strength of the wire is diminished to such a degree that the spring 8 mechanically fractures it at a temperature much below its melting point. In the construction shown in Fig. 2 the wire 12 is stretched between a spring-urged arm 13 and a contact-arm 15, the circuit comprising the fixed contact 17, the arm 15, the wire 12, the arm 13 back to the other terminal. The contact-arm 15 is maintained in the position shown, against the action of the spring 14, by the latch 18 which may be tripped to reiease the contact-member and open the switch by pulling on the rod 19. When the wire is broken, thereby breaking the circuit, the contact member remains in the position shown and, to re-set the fuse, the contact-member is released by hand and swung round into proximity to the arm 13 so that a new fuse can be introduced. In the construction shown in Fig. 3, when the arm 21 is released by the breaking of the wire, an extension 27 thereof engages the rod 28 and trips the contact-arm 22 which is acted on by the spring 24. In this case the main circuit is through the contact 29, the contact-arm 22, the resistance 30, which increases with increase of current, and the other main terminal. The fuse wire 20 is in a shunt circuit across the resistance 30 which is so proportioned that although a predetermined over load will not immediately cause the breakage of the wire, this overload if it persists for a certain time will increase the resistance 30 and consequently the current in the shunt circuit to a point whereat the wire breaks. In a modification of this construction, the contact-arm is latched in the closed position and remains latched when the wire is broken but can be unlatched by pressing a trigger on the handle of the contact-member.

Patent GB-404922-A (GB)
Title: Method of making moulded articles
Filed: 1932-04-20
Abstract: Moulded articles are formed by two or more layers of different composition, adjacent layers being connected by welding together the ingredients which are common to these layers.  The change in the composition of the article may be abrupt at the junction of the layers or a series of layers may be arranged with a gradual increase or decrease of a particular constituent so that the change is progressive.  In the application to moulded packings or bearings, a main portion of graphite, rubber, grease and asbestos is surrounded in part by layers without graphite or with much less than in the main or rubbing portion.  In one construction the main portion is triangular in cross-section and the outer layer surrounds two sides of the triangle only.  To produce a receptacle with a rigid bottom and flexible rims or edges, the base may be formed of artificial resin, the main walls of artificial resin, rubber, and sulphur and the edges of pure rubber.  In this latter case, the resin forms the common welding material between the base and the resin walls, and the rubber between the main walls and the edges.  The welding may be effected by heat or pressure or both. Metallic powder may be introduced into the surface layer for decorative purposes.

Title: A process for the production of silicon-containing trioxane copolymers
Inventor: EMDEN WOLFGANG VON DER
IPC: C08G2/00
Filed: 1966-03-15
Abstract: 1,142,646. Silicon-containing copolymers of trioxane; sila formals and esters. FARBENFABRIKEN BAYER A.G. 15 March, 1966 [15 April, 1965], No. 11337/66. Headings C3P and C3S. Silicone-containing copolymers are prepared by copolymerizing a formal or a carbonic acid ester of a bis-(hydroxyalkyl) silicon cornpound with trioxane at from 50‹ C. to 120‹ C. in the presence of a cationic initiator. Prefered copolymers are those of trioxane and a compound of the formula where X represents two hydrogen atoms or an oxygen atom, n = 1, 3 or 4, m = 0, 1, 2, 3 or 4 and o = 0 or 1, R<SP>1</SP> is -CH 3 , -O-Si(CH 3 ) 3  Particularly preferred copolymers contain 99À5 to 95À0 mol per cent of trioxane and 0À5 to 5 mol per cent of the formal or carbonic acid ester. A preferred copolymer is with 2,2,8,8-tetramethyl-2,8-disila-1,4,6-trioxa-cyclooctane. In Example 9 the condensation product of bis- (hydroxymethyl)-tetramethyl-disiloxane and pformaldehyde is used. Cationic initiators include strong acids e.g. sulphuric, perchloric, alkane-sulphonic and p-toluene sulphonic acids and Lewis acids e.g. boron trifluoride and its adducts and 2-methyl-1,3-dioxolenium fluoborate. The process may be carried out as an emulsion or solution polymerization in an inert organic liquid. It may be carried out as a bulk copolymerization, the catalyst being melted with the trioxane and the comonomer added simultaneously, or the trioxane being melted initially with the comonomer and then the catalyst added, possibly in an inert solvent. Further comonomers may be employed e.g. ethylene oxide, 1,3-dioxolane, 1,3-oxthiolane, bismethane - sulphonyl - imidazoline or hexamethyl - cyclotrisiloxane. The sila-formals employed in the invention may be obtained by treating bis-(hydroxy alkyl) - silicon compounds with formaldehyde or formaldehyde-yielding substances (e.g. paraformaldehyde or fomals of low-boiling alcohols) in the presence of catalyst e.g. small quantities of strong acid (e.g. p-toluenesulphonic acid or sulphuric acid) with moderate heating, the water which forms being removed by azeotropic distillation with an inert water-immiscible solvent or, in the case of re-acetalization, the volatile alcohol formed being distilled off. The corresponding carbonic acid esters are obtained in a similar manner by reaction with phosgene.
