Filed: 1972-08-31
Abstract: 1394130 Threaded fasteners ILLINOIS TOOL WORKS Inc 31 Aug 1972 [1 Sept 1971] 40467/72 Heading F2H To prevent electrolytic corrosion between the head of a metal fastener, e.g. a steel selftapping screw 11, and a metal sheet 23 engaged by the fastener, the head, which has a non- circular portion 13 and a flange 14, is encapsulated by a complementary shaped cap member 17 which prevents direct contact between the fastener and the sheet, and which is made of metal, e.g. aluminium or an alloy of aluminium or magnesium, having a different contact potential from that of the head 13, 14. The member 7 is preferably of the same material as the sheet 23 to minimize corrosion between it and the sheet, and the head 13, 14 may be plated with a metal such as zinc or cadmium.

Title: Improvements in the dispersion of solids in liquid media
Inventor: RAVAULT FRANK ERNEST GEORGE
IPC: C09K23/00
Filed: 1960-11-25
Abstract: A dispersion of a particulate solid material of greater than colloidal size in a liquid medium which contains within it a flocculent material in quantity sufficient to constitute a loose network of flocks within the medium.  The inclusion of the flocculent material does not increase the viscosity of the medium, that the network of flocks tend to retard the settling of the solid particulate material and that when, in due course, such settling may occur, redispersion of the sediment is very readily effected since the flocks prevent close packing of the solid material and the medium is of a low viscosity.  The flocks produced should have an almost negligible apparent density, i.e. a small weight of the material occupying a very large volume in the liquid carrier.  Flocculants specified are silica montmorillonite or wax. Silica for moulds and aluminium flakes may be dispersed.ALSO:An alkyl ammonium montmorillonite gel is dispersed in toluene and flocculated with white spirit containing a polyphenyl resin binder by mixing. Aluminium flake is added and forms a stable suspension.

Title: Improvements in the production of sulfanilamidodiazines
IPC: C07D237/20
Filed: 1958-12-17
Abstract: Amino benzene sulphonamido - substituted - pyridazines, -halopyridazines, -pyrimidines and -halopyrimidines are prepared by mixing the corresponding halo diazine having at least one halogen atom on a ring carbon alpha to a nitrogen atom, and sulphanilamide with an alkali metal carbonate and heating the mixture at a fusion temperature above 100 DEG C. with agitation until reaction substantially ceases, the reaction being effected in the presence of an amount of fluidizing agent, as hereinafter defined, which has been added before or during the fusion.  The said agent has a boiling point above the fusion temperature and is an aliphatic amide containing 2 or 3 carbon atoms in the acyl radical, e.g. acetamide, dipropylene glycol a 1 : 3- or other butylene glycol, benzamide, a polyalkylene glycol containing at least 4 monomeric groups, e.g. polyglycol 1200, or a C1-6 alkyl ether of diethylene glycol, e.g. the mono- or di-ethyl ether; the agent is used in an amount equal to at least one-eighth the weight of the halodiazine reactant, and sufficient to make the fused mass stirable.  The fusion temperature normally does not exceed 160 DEG C.  In examples, 3 : 6-dichlor pyridazine is reacted with sulphanilamine in the presence of K2CO3 and various of the above fluidising agents at 133 DEG C.-145 DEG C. yielding 3-sulphanilamido-6-chloro pyridazine whose recovery and purification is described.  In comparative experiments the fluidizing agent is replaced by formamide, dimethyl formamide or triethylene glycol, the yields of product thereby being lowered. The method may also be used to prepare 2-sulphonailamido pyrimidine.  Reference has been directed by the Comptroller to Specification 730,949.

Abstract: 1,253,662. Laminates. H. H. ROBERTSON CO. 2 Sept., 1969 [7 Sept., 1968], No. 42700/68. Heading B5N. [Also in Division B2] An insulating layer of rigid closed cell polymeric foam is applied to a substrate by heat activating an initial coating of rapidly reacting polymeric foam producing components on the substrate and applying at least one further coating of the same or other rapidly reacting polymeric foam producing components over the foamed initial coating so that the further coating is activated autogenously by the heat of the initially applied foamed coating. The polymeric foam may be produced by the reaction of rapidly reacting polyisocyanate and polyol components in the presence of an inert volatizable blowing agent, e.g. trichlorofluoromethane. The foam producing components may be applied by spraying. The heat required for activation of the initial coating may be provided by pre-heating the substrate or by the subsequent application of heat to the initial coating e.g. by means of radiant heat electric lamps. Cooling may be effected between each application of the coatings to prevent overheating and ensure controlled uniform expansion of the foam. Machining of the top surface of the foamed polymeric mass may be effected by means of a planing machine and of the side edges by means of rotary cutters of desired profile. The substrate may be flat, e.g. plasterboard, or profiled, e.g. corrugated metal sheets. Building panels may be produced by coating the surface of the foam with a polyurethane elastomer and then bonding thereto asbestos felt coated with polyvinyl chloride, before curing of the elastomer is complete.
