Title: Improvements in or relating to methods of making wax models for lost-wax casting
IPC: B29C67/24
Filed: 1959-12-01
Abstract: 934,099. Making wax models for lost-wax casting. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 1, 1959 [Dec. 4, 1958], No. 40794/59. Class 87(2). Molten wax is passed through a liquid cooling system, the temperature of which is kept constant with the aid of a heat source, and forced into a mould in the plastic state. The wax is stored in a heated pressure container 1 having an outlet 4 connected with a heatexchanger comprising a helical tube 8 leading to a nozzle 10 and mounted in a liquid bath 15 for cooling, which bath contains a helical heating element 14 the temperature of which can be controlled for controlling the cooling. The outer wall of the bath 15 contains a helical tube 16 through which water flows so that the liquid, e.g. oil, inside the bath is cooled continuously. Forcing the wax in a plastic state is claimed to yield more accurate wax models than the use of molten wax, but the temperature of the plastic wax is critical since small temperature fluctuations involve considerable viscosity variations, hence the provision of the adjustable heat source.

Title: New aryloxy-aliphatic hydrazines
Filed: 1959-12-01
Abstract: The invention comprises monoaliphatically substituted hydrazines the aliphatic radical of which is substituted by an aryloxy radical and acyl derivatives of these hydrazines with the exception of 2-phenoxyethylhydrazine and physiologically tolerable acid addition salts of these compounds.  The aryl residue may be substituted by a halogen atom, a hydroxyl group substituted by a C1-6 aliphatic or cycloaliphatic hydrocarbon radical or by a C1-6 alkyl radical.  The aliphatic radical may be substituted by free hydroxyl groups.  The compounds are prepared by treating an aryloxyaliphatic compound whose aliphatic residue contains a radical replaceable by or convertable into a hydrazine group which may be acylated so as to replace or convert the said radical into a hydrazine group.  A radical replaceable by a hydrazino group is especially an epoxy group or a reactive esterified hydroxyl group and a radical convertable into a hydrazino group is a hydrazone group.  The hydrazines may be acylated or acyl desivatives hydrolysed.  1-Phenoxypropyl-(2)-chloride is prepared by reducing phenoxyacetone to 1-phenoxypropanol-(2) with sodium borohydride and reacting the alkanol with thionyl chloride.  N - [1 - Phenoxypropylidene - (2)] - N1 - acetylhydrazine is prepared from phenoxyacetone and acetylhydrazine.ALSO:Pharmaceutical compositions comprise monoaliphatically substituted hydrazines, the aliphatic radical of which is substituted by an aryloxy radical, and acyl derivatives of these hydrazines with the exception of 2-phenoxyethyl hydrazine and physiologically tolerable acid.
