Abstract: 1,274,732. Strengthening glass. GLAVERBEL. 25 June, 1969 [12 Sept., 1968], No. 32150/69. Heading C1M. Compressive surface stresses are set up or increased in at least part of a body of glass, glass-ceramic or ceramic by a chemical tempering treatment using a liquid medium, in which the liquid medium is continuously supplied to and streams along the body. The liquid medium may be supplied from jets, and body and jets may be in reciprocating relative motion. The liquid may be, e.g. molten KNO 3  or a mixture of LiNO 3  (2 mol. per cent) and NaNO 3  (98 mol. per cent), and may be regenerated and recycled after use. Differential tempering may be carried out by varying the flow rates of the jets or by varying the liquid used. The liquid may be streamed along the body in the presence of a gas which influences ion diffusion into the body, e.g. H 2 O, CO 2 , SO 2 , SO 3  or halogen. The ion diffusion may be assisted by an electric field, which may be alternating. Suitable apparatus is disclosed. Specification 1,274,733 is referred to.

Filed: 1938-11-05
Abstract: 523,595. Magnetic compasses. KOLLSMAN, P. Nov. 5, 1938, No. 32151. [Class 97 (ii)] [Also in Group XXXVIII] The magnet 15 of an aircraft compass controls the transmitter 45 ... 47 of an electric signalling system through magnets 55, 56 carried by the transmitter shaft. The Z-shaped rotors 41, 41<SP>1</SP> of the transmitter and receiver are excited by coils 45, 45<SP>1</SP> from the same source of A.C., preferably of the order of 400 cycles per second, and the interconnected stators consist of two sets of windings 46, 47 and 46<SP>1</SP>,47<SP>1</SP> at right angles. The system is substantially'dead-beat and this quality is made use of to minimize the effects of disturbing movements and accelerations of the aircraft by arranging the transmitter with its axis vertical and the receiver with its axis horizontal. Preferably the natural frequency of oscillation of the signalling system is higher than that of the directional magnet. The compass magnet 15 is carried in a float provided with clamping vanes and pivoted for rotation and tilting about a vertical axis at a point 25 cooperating with a resiliently mounted jewel 19. The compass bowl is filled with fluid to a definite level through a tube 40 and is divided into two compartments which are in communication by means of a hole 36 to allow for expansion and contraction of fluid and a vent conduit 35 for the escape of bubbles. The transmitter shaft carries a pointer 57. Adjustable compensating magnets are provided at 63, in known manner. Electrical connections are made by a plug and socket 61. Specification 524,801 is referred to in the Provisional Specification.

Abstract: 329,313. Imperial Chemical Industries, Ltd., Morgan, H. H., and Drummond, A. A. Nov. 9, 1928. Ester condensation products.-Synthetic resins are prepared bv removal of the solvent from varnishes obtained by incorporating phenolic compounds and formaldehyde with fatty acid esters in the presence of a volatile organic sol. vent. Suitable phenolic compounds are phenol and its homologues and mixtures of phenols including coal tar fractions such as cresylic acids and creosote oils. Suitable fatty acid esters are wood oil, linseed, perilla, soya bean, fish, olive, rape-seed, cotton-seed or castor oils. Phenolic compounds and formaldehyde may be heated with fatty acid esters in the presence of organic solvents such as cyclohexanol and homologues, benzyl alcohol, monoalkyl ethers of ethylene, glycol, ketones, esters or turpentine and preferably with a catalyst such as caustic soda or boric acid in methylated spirit. Alternatively, phenolic compounds and formaldehyde are boiled with excess of an organic solvent such as cyclo-hexanol or homologues, aliphatic alcohols or ketones, benzyl alcohol or turpentine in the presence of an alkaline catalyst, after which the product is acidified with a weak acid such as boric acid and distilled in the presence of a high boiling solvent such as benzyl alcohol or cyclohexanol until all water is removed. A fatty acid ester is added and distillation continued until a drop of the mixture heated on a metal plate dries clear and glossy. Driers and colours or pigments may be incorporated in the varnish or resin.
