[Class 99 (ii)] [See also Groups XVII and XXIX] Pipes &c., which are proof against chemical corrosion, are formed by applying a mixture comprising rubber, mortar-forming constituents such as aluminous or Portland cement or gypsum, and vulcanizing agents to a metal foundation, such as perforated sheet metal, wire netting, or expanded metal, which is coated with rubber on one or both sides, in such a manner that a layer of hard or soft rubber is afforded at those parts which are exposed to chemical action or to mechanical wear. The rubber in the mixture for the constructional material is preferably in the form of a dispersion such as latex, and if desired quartz, kaolin or fibrous substances such as asbestos and shredded leather may be added to the mixture. A flanged pipe may for instance, be made from a tubular skeleton of wire netting to the ends of which supporting flanges of sheet-metal are attached, a flexible tube of unvulcanized rubber being drawn into the skeleton and caused to adhere thereto by pressure, with or without the aid of a cementing agent, rubber annuli being in a similar manner applied to the outer faces of the flanges. The foundation so formed is vulcanized to hard rubber. After vulcanizing, the exposed surfaces of the skeleton body and the flanges are coated with a mass of the mixture of constructional material, which is allowed to dry and harden, and vulcanized. Examples of suitable mixtures for the rubber coating and for the constructional material are given. Specification 369,561 is referred to.

Title: Reaction products of polymers with polyisocyanates or polyisothiocyanates
Inventor: JONES FREDERICK ARTHUR
IPC: C08G18/08
Filed: 1954-03-09
Abstract: Polyurethane rubber intermediates are stabilized by incorporation of an organic acid halide.  Prior to moulding the acid chloride is neutralized by milling in an organic or inorganic base so that curing may take place.  The polyurethane may be the reaction product of a polyisocyanate with a polyether, polyester or polyesteramide. Additional polyisocyanate may be incorporated, prior to neutralizing the acid chloride, to bring the proportion of polyisocyanate up to 1.4 to 1.6 mols. per mol. polyester if the initial quantity of polyisocyanate is less than this.  The intermediate product may be reacted with polyfunctional compounds such as water, polyhydric alcohols, polyamines and aminoalcohols.  The acid chloride may be the chloride of an aliphatic aromatic mono- or dibasic acid.  The chloride may be a carbonyl or sulphonyl chloride.  In Example (1) one hundred parts of polyglycol adipate of molecular weight 1650 and acid number 1-4 were reacted with 18 parts of 1.5 naphthalene diisocyanate and the product with two parts 1,4 butane diol.  To separate portions were then added 0.1, 0.25, 0.4 and 0.5 per cent by weight phthaloyl chloride and milled to test sheeting and tackiness qualities.  The various products were then divided into two portions into one of which was milled 1 per cent diphenylamine, this portion then being moulded directly.  The other portion was stored for 24 hours, milled with 1 per cent diphenylamine and moulded.  The processing properties of the various portions are compared.  In Example (2) the physical properties of test specimens are compared after storing for from 2-6 days before incorporation of diphenylamine and 2.21 dipyridylamine as neutralizer for the p-nitrobenzoyl chloride used as stabilizer- Six other examples are given.

Abstract: 867,093. Sheet-delivery apparatus. GOLDING, W. F. Feb. 19, 1958 [Feb. 28, 1957], No. 6792/57. Class 100(1) Sheet delivery apparatus for printing or like machines comprises conveyer means for conveying a sheet from the machine and release means for releasing the sheet selectively at one or other of two release positions spaced apart along the line of travel of the conveying means and defining an upstream and a downstream release position respectively. As shown the machine comprises a frame 1 to which is journalled a sprocket shaft 2 carrying a sprocket 3 for endless conveyer chains 4. The chains 4 have gripper bars 6 carrying gripper jaws 7 which are opened by means of a lever 8. The grippers are provided at intervals along the chains corresponding to the diameter of the sprocket 3 and the chains are intermittently driven. The gripper mechanism may be as described in Specifications 791,559 and 819,000. The lever 8 is operated by levers 11 secured to an off-set shaft 12 mounted to revolve with the sprocket 3 and carrying an exterior lever 14 having a roller 15 which cooperates with a stationary track cam 16. The arrangement is such that the levers 11 are positioned for operating the levers 8 every time a gripper bar 6 carried by the chains 4 arrives adjacent the sprocket 3. The cam 16 includes an inner surface 17 having depressions 21, 22, an outer surface 18, and a movable outer cam member 19 having lobes 23, 24 corresponding to the depressions 21, 22. The cam 19 is pivoted on a pin 20 secured to the frame 1. Pivoting of the member 19 causes either the lobe 23 or the lobe 24 to project into the path of the roller 15 to open the grippers at either a downstream position 46 or an upstream position 47. The lever 19 is connected by a link 25 to a lever 26 pivoted to a rod 27 and connected through a connecting rod 28 to a manually operable eccentric 29. Also pivoted on the rod 27 is a bracket 32 which carries rollers 35 which define an arcuate path adjacent the sprocket 3 and prevent radial movement of the gripper bars 6. Normally the lever 19 is set so that sheets are deposited on a pile 48. When it is desired to inspect a sheet the lever 19 is set so that the grippers open in position 46 and the sheet is deposited on a table 45. To assist in delivering sheets to the table 45 a roller 37 is provided which is connected by gears to the sprocket 3 and which co-operates with a sheet engaging segment 38 on the shaft 2. In an alternative embodiment instead of the cam 19 and two depressions in the surface 17 of cam 16 a cam with a single lobe and depression may be used which can be rotated to bring the lobe and depressions into the two release positions.
