Patent GB-631057-A (GB)
Title: Manufacture of thymoxy-acetamidines
Filed: 1947-09-09
Abstract: N-Dimethyl- and N-diethyl-thymoxyacetamidine and their salts (e.g. hydrochlorides and hydrobromides), which possess therapeutic (anticholinergic and atropine-like) activity, are manufactured by reacting dimethylamine or diethylamine or a salt thereof with a nitrogen-containing functional derivative of thymoxyacetic acid unsubstituted at the nitrogen (e.g. its N-unsubstituted iminoethers, iminothioethers, imide halides, thioamide, amide or amidine or its nitrile), or compounds yielding such derivatives under the reaction conditions.  The reaction may be effected in the presence or absence of diluents or condensing agents, at low or elevated temperatures and at various pressures.  Examples describe several methods of carrying out the process. Specification 476,611 is referred to.  Iminoethers of thymoxyacetic acid are prepared in the form of hydrochlorides by treating thymoxyacetonitrile with a solution of hydrochloric acid in ethyl, methyl or benzyl alcohol or cyclohexanol.  Thymoxyacetonitrile is obtainable by condensing thymol with chloroacetonitrile.  The ethyl iminothioether of thymoxyacetic acid is prepared by passing dry hydrogen chloride into a solution of thymoxyacetonitrile and ethyl mercaptan in dry ether.  Thymoxacetothioamide is obtained by heating thymoxyacetonitrile with ethanolic ammonia and hydrogen sulphide under pressure, or by treating thymoxyacetamide with phosphorus pentasulphide and sodium sulphide in xylene.

Title: Temperature responsive elements
Inventor: DAVIDSON DONALD WEST
IPC: B65D79/02
Filed: 1960-07-15
Abstract: 910,520. Temperature indicators. NATIONAL RESEARCH COUNCIL. July 15, 1960, No. 24805/60. Drawings to Specification. Class 97 (3). A temperature-responsive element for indicating spoilage of a product such as frozen food, pharmaceuticals or photographic material, due to overheating comprises an inert oil or wax or mixture thereof having a melting range, i.e. not a sharply defined melting point, in the neighbourhood of the spoilage temperature and in contact therewith a permeable member which provides a diffusion path for the oil or wax when melted. By " inert " oil or wax is meant one which is not chemically reactive and undergoes little or no oxidation when exposed to air for long periods. In an example a greasy blob of a hydrocarbon oil, which is naturally coloured or contains colouring matter, is applied to the inner wrapper of a food product and the outer wrapper is then applied and the product frozen so that the blob is solidified. If the food product is exposed to temperatures above the spoilage temperature, the oil blob melts and diffuses through the outer wrapper, the speed of diffusion depending on the excess of temperature above the spoilage temperature.
