Abstract: 556,300. Propelling aircraft. UNITED AIRCRAFT CORPORATION. Dec. 10, 1941, No. 15927. Convention date, Dec. 14, 1940. [Class 4] [Also in Group XXIV] Consists in a reduction gear mechanism between an engine crankshaft and a propeller shaft in which the propeller shaft is supported independently of the crankshaft so as to have only torsional connection therewith and to be isolated from all beinding and eccentric movements thereof. The crankshaft 16 is mounted in a bearing 18 in a partition 20 of the crankcase 10 the bearing being clamped by an annular valve-cam support 22. An extension 24 of the crankshaft carries a collar 26 splined therto and secured by a nut 30. This collar has splines 32 engaging internal splines at one end of an annualur driving member 34 the opposite end of which is similarly splined to a second annular drive member 38 supported in a bearing 40 carried by a partition 14 between the casing 10 and a nosing 12. The splines at the ends of member 34 are a loose fit in the corresponding splines on the members 26, 39 so that member 34 has freedom of angular movement. Within the member 38 is a bearing 42 supporting the rear end of the propeller shaft 44, the bearing being secured thereon by abutments 46 and 48. The front end of the propeller shaft is supported by a bearing 49 secured by plates 50, 51 and abutments 54, 55. The drive member 38 is splined to a gear 58 supported on shaft 44 by a bearing 60, and meshes with bevel planet gears 64 carried by a cage 62 integral with shaft 44. The planets mesh also with a fixed reaction gear ring 66 supported on shaft 44 by a bearing 68 and splined to the fixed flange 74 on plate 51. Lubricating oil may be transferred from crankshaft to propeller shaft by a flexible connection 76, 78.

[Class 2 (iii)] Compositions of improved stability to degradation by ultra-violet light, heat, oxygen or moisture, are prepared by incorporating in a synthetic linear polyamide an N : N<SP>1</SP>-polymethylene -bis-ortho-hydroxybenzamide having the formula  where R and R<SP>11</SP> are hydrogen atoms or monovalent aliphatic radicals connected to nitrogen through carbon; R and R<SP>11</SP>may be different or identical; R<SP>1</SP> is an aliphatic radical containing at least two, and preferably from two to twelve carbon atoms, and which is attached to the nitrogens through carbon ; and RX and RY are hydrogen atoms or alkyl substituents, and may be different or identical. These N : N<SP>1</SP>- polymethylene - bis - ortho - hydroxybenzamides are readily prepared by treating salicylic acid, a salicylic acid ester or salicyl chloride, with an aliphatic diamine, and many such compounds are specified. Superpolyamides, mixtures of superpolyamides, modified superpolyamides, and interpolyamides may be treated, and the stabiliser may be incorporated therein by immersing the polyamide, in the form of a shaped solid, in a dilute solution of the former in a non-solvent for the polyamide, or by mixing the materials at an elevated temperature, or by dissolving both materials in a mutual solvent, such as formic acid, a phenol, or a mixture of chloroform and methanol. The amount of stabilizer used is generally from 0.1 per cent: to 25 per cent. by weight of the polyamide. The stabilised compositions may also contain plasticizers such as sulphonamides, phenols, esters, ether esters, lustre-modifying agents, pigments, dyes,. antioxidants, oils, antiseptics, cellulose derivatives, resins and fillers, and they may be used in the preparation of yarns, fabrics, bristles, fishing leaders, fishlines, rods, tubes, films, ribbons, sheets, safety glass interlayers, moulded articles and coating compositions. According to examples : (1) a superpolyamide prepared from hexamethylene diammonium adipate and epilson-caprolactam; and (2) a polyester-polyamide interpolymer prepared from ethylene glycol, adipic acid and hexamethylene diammonium adipate; are stabilized by the incorporation of N:N<SP>1</SP>- hexamethylene - bis - ortho hydroxybenzamide.
