Title: A method of preparing a dispersion of fluoro-carbon resin for painting and the said dispersion obtained thereby
IPC: C08J3/12
Filed: 1956-08-08
Abstract: Dispersions for painting of fluorocarbon resins, e.g. polymers of tetrafluoroethylene or monochlorotrifluoroethylene or their copolymers with vinylidene chloride, ethylene, styrene or acrylic acid esters, are made by heating the resin in powdered form at a temperature near the "no-strength temperature" of said resin, i.e. within the range of the melting-point and up to the decomposition temperature of the resin, for a period of time sufficient to reduce the distance between molecules of said resin, crushing said resin into fine particles and dispersing it in a medium such as methanol or other alcohols, ketones, hydrocarbons, halogenated hydrocarbons or esters.  The heating may be carried out by passing the resin through a heated apparatus or by heating the resin when dispersed in a liquid with a boiling-point above the no-strength temperature of the resin, e.g. dibutyl maleate. By this heat-treatment the value of the specific gravity is varied and a thicker coating may be applied in a single painting operation.

Abstract: 382,699. Moulding glass flowerholding blocks. DAVIDSON, T., Teams Glass Works, Gateshead-on-Tyne. Aug. 29, 1931, No. 24358. [Class 56.] Relates to the manufacture of flower-holding blocks by the method described in Specification 7830/10, [Class 56, Glass], in which the glass is pressed by a plunger having fingers that form holes which do not extend completely through the block. The bottom of the block is subsequently pierced in line with the holes in order to complete the passages through the blocks. According to the present invention, projections 11, Fig. 1, are formed on the interior of the mould 10 in line with the fingers 16 of the plunger 14, so that the sections of glass left at the bottoms of the holes are relatively thin and are easily pierced. The projections 11, and the ends 15 of the fingers 16, may be flattened, as shown, or they may be provided with raised portions 11<1>, 151, Fig. 1g, which almost completely puncture the glass. The raised portions 11<1>, 15<1> may be of various shapes. The mould 10 is provided with a cover 12 having apertures through which the pressing- fingers pass, and in order to accommodate varying quantities of glass put into the mould, the cover may be formed with a cylindrical projection 13 which is a sliding. fit into a cylindrical portion 12<1> at the top of the mould. The cover 12 can rise, if there is an excess of glass, when the plunger is fully depressed. In another construction, shown in Fig. 1a, a recess 101 is formed between the cover 12 and the top of the mould to receive any excess glass. Both these arrangements may be combined so that the recess 10<1> is uncovered only when the cover 12 rises. A raised rim 13<1> may be provided on the rim of the cover to form a groove on the top of the glass block for use as a support when the block is inverted.

Abstract: 398,342. Door-operating appliances. POTTER RAX GATE CO., Ltd., Wilton Works, Shepperton Road, Islington, and COLEMAN, F. G., 104, Croydon Road, Anerley, both in London. Sept. 2, 1932, No. 24495. [Class 65 (i).] A sliding or collapsable gate or door is arranged to be automatically closed after being partially closed by hand, the movement of the gate towards the closed position tripping a catch to bring into action a spring which is stressed during the opening movement. The device, shown applied to a lazy-tongs gate, comprises a cylinder D, slidably mounted on a rod A fixed above the gate, and a spring inside the cylinder between the righthand end of the latter and a stop fixed on the rod A, so that the spring is compressed by movement of the cylinder towards the left. The right-hand end of the cylinder has a lateral lug C which is engaged by a projecting member F mounted on a member J of the gate. As the gate is opened, the cylinder is pushed back by the member F until the lug C is engaged by a spring-pressed catch E pivotally mounted above the gateway. Immediately after this the member F, which is slidably mounted in a housing P, Fig. 3, on the gate, is drawn down against a spring N in the housing by a roller Q on the member F engaging a projection G on the gate track bar H, so that the member F passes under and releases the lug C on the cylinder and the gate is free of the cylinder for further opening. During the closing movement, immediately after the member F passes under and comes to the right of the lug C on the cylinder a bracket M on the housing P engages a depending part K of the catch E and moves the catch to free the cylinder, which is then moved to the right by the spring within it, carrying the gate to the closed position by engagement of the parts C, F. The part K of the catch E is pivoted so that it can swing upwards to the left when the bracket M engages it during the opening of the gate.
