Abstract: 1436889 Crosslinking fluorocarbon polymers using radiation INTERNATIONAL STANDARD ELECTRIC CORP 24 July 1973 [28 July 1972] 35167/73 Heading C3P [Also in Division B2] A polymeric material comprising (a) a polymer of one or more ethylenically unsaturated fluorocarbon monomers and (b) a triallyl ester of an aromatic polycarboxylic acid (the acid being at least a tricarboxylic acid) is crosslinked by the application of ionizing radiation. Examples of polymer (a) are ethylene-tetrafluoroethylene, ethylene-chlorotrifluoroethylene, tetrafluoroethylene - vinylidene fluoride, tetrafluoroethylene - hexafluoroproplylene, vinylidene fluoride - hexafluoropropylene and vinylidene fluoride - hexafluoropropylenetetrafluoropropylene copolymers, and polyvinylidene fluoride. Suitable as component (b) are the trialkyl esters of trimellitic and trimesic acid. In examples a small proportion of magnesium oxide is incorporated in the polymeric material as a stabilizer, and the ionizing radiation used is an accelerated electron beam. A useful application of the invention is the production of extruded, crosslinked, insulating coatings on wires.

Title: Improvements in or connected with telescope observation instruments
IPC: G02B7/28
Filed: 1935-12-20
Abstract: 466,823. Telescopes. BARR & STROUD, Ltd., and STRANG, J. M. Dec. 20, 1935, No. 35315. [Class 97 (i)] A telescope is provided with compensating means to keep the magnification constant as the focus is varied. In Fig. 5 the eyepiece A is moved for focusing and the projector lens C is simultaneously moved to produce the compensation. Both movements are effected by the knob 3 working lead screws 2, 6 carrying nuts 4, 7 to which the lenses are attached. The pitch of the screw 2 is uniform but that of 6 is non-uniform and so shaped to produce the movement of the lens C required for the magnification correction. Provision may also be made for moving C alone to obtain variable magnification per se. In Fig. 3 the eyepiece A is moved as a whole for focusing and its parts A<1>, A<2> are moved relatively to one another for magnification correction. In Fig. 4 the focusing is carried out by the prism D and the magnification correction by the lens C. Alternatively focusing may be effected by introducing a lens between the eyepiece lenses, in such a position that its nodal point coincides with that of the eyepiece combination so that its introduction does not alter the magnification. The optical system of Fig. 5 can be so arranged that focusing may be effected without change of magnification by moving the projector lens C alone.

Abstract: 781,492. Casting and moulding processes; cores. CHRYSLER CORPORATION. Dec. 10, 1954, No. 35830/54. Class 83 (1). [Also in Group XXVI] A turbine-blade is formed with a narrow airpassage or passages extending therethrough from the root to the tip for the flow of cooling- air. The blade is formed by placing an insert 44, 48 which corresponds to the shape of the airpassage to be formed in the blade, in a die 60, Fig. 3, the two parts 62, 64 of the die abutting along the surface 66. The die has a cavity 68 corresponding to the aerofoil section of the blade. Filling-material 70, as used in precision investment-casting, e.g. wax or a low-melting- point alloy of aluminium, cadmium or lead, is poured into the die to fill the cavity 68, Fig. 4. The die is then replaced by a frangible investment-mould 56, Fig. 5, of ceramic, plaster, &c., and the filling-material is then removed to leave the insert suspended in the cavity as in Fig. 6. The blade-material, which may be a highmelting-point alloy, is then poured into the mould 56 as in Fig. 2, and the mould is subsequently removed by breaking away. The insert, which may be formed of material which may be readily etched out of the blade, such as nickel, aluminium, cadmium or copper, is finally removed. The insert may alternatively be removed by melting or leaching.
