Title: Improvements in or relating to engine cowl supports
IPC: B64D27/04
Filed: 1941-11-24
Abstract: 556,238. Resilient mountings. UNITED AIRCRAFT CORPORATION. Nov. 24, 1941, No. 15143. Convention date, Jan. 18. [Class 108 (iii)] [Also in Group XXXIII] The cowling of an aircraft engine is supported entirely from the engine by frictionally damped resilient means which allow a certain amount of radial and circumferential movement while strongly resisting axial movement. A radial cylinder engine with two banks of cylinders is shown from which a cowling 18 is supported by resilient fittings, 26, 36, 38, 40 secured to two rows of projections on the cylinder heads. Each resilient element consists of an open cup-shaped member 42, Fig. 2 secured by metal fins 44 and bolts 46, 48 to the engine. A rubber block 50 is bonded to the member 42 and to a disc 52 having a stem 54 to which is secured a collar 64 connected in the case of a front fitting, by a link 70 to a bracket 74 on the inside of the cowling. A disc 56, a sliding fit in the cup, is sandwiched between the disc 52 and a disc 58 slidable on the stem 54. A spring 60 presses the discs together so as frictionally to damp any movements transverse to the stem, which movements are resiliently resisted by the rubber block in shear. Movements parallel to the stem are resisted by the rubber in compression. The rear fittings have direct connection between the stems 54 and extended brackets on the cowling. Where an engine with a single bank of cylinders is used the cowling is supported by a single row of fittings of the form shown in Fig. 4. In this case a cup 78 is closed by a screwed cap 104 and blocks of rubber 88, 90 are placed on opposite sides of the disc 92 on a stem 100 secured directly to a bracket 98 on the cowling. The resilient elements may be calculated to maintain the periodicity of the cowling and its supports different from or substantially equal to that of the engine.

Title: Improvements in or relating to moulding and thermoplastic compositions and a processfor the manufacture of products therefrom
IPC: C08K5/105
Filed: 1942-04-29
Abstract: A moulding or thermoplastic composition suitable for the manufacture of artificial hands, fingers, noses, ears, lips, &c. for use in plastic surgery, for washers and abrasives and as resilient linings for polyvinyl or polymethylmethacrylate dentures &c., comprises a polymeric and/or monomeric methyl methacrylate and between 5-12 per cent, preferably 50-100 per cent, of phenyl salicylate.  Part of the phenyl salicylate may be replaced by other phenolic substances; solvents, pigments, dyes and other plasticizers may be included and several additions-up to 10 per cent-of other acrylate or vinyl resins, e.g. styrene resins, may be added.  To increase softness, up to one-half of the phenyl salicylate may be replaced by a plasticizer such as dibutyl phthalate or tricresyl phosphate.  An anti-catalyst, e.g. hydroquinone, may be added, particularly when the composition includes monomeric methyl methacrylate or a liquid polymer thereof. The composition may be introduced into a mould and heated to produce rubber-like articles; or may be fused, by heating, to produce material suitable for injection moulding; heating is preferably between 60-100 DEG  C.  Powdered or comminuted composition may be sprayed through a heated nozzle to an acrylate or vinyl resin article, e.g. a dental plate, or to form a flexible hinge between hard sections, e.g. of polymethyl methacrylate. Sheets resembling dental rubber are obtained by passing the composition between heated rollers.  For moulding, tin moulds or plaster moulds lined, e.g. with sodium silicate, may be employed. Composite hard and soft articles are obtained by suitably distributing harder and softer compositions in the mould. Examples detail preparation of various compositions and the production therefrom of moulded articles, rubbery and spongy masses, sheets for washers and gaskets and plastic surgery parts, i.e. thumb joints, noses, articulated fingers and finger bones. Specifications 358,534 and 550,252 are referred to.
