Patent EP-0155600-B1 (EP)
IPC: B65D77/30
Filed: 1985-03-07
Granted: 1988-09-21
Abstract: Opening arrangements on packing containers are often of the type which comprises a prefabricated pouring opening. The cut edges appearing around the pouring opening must be protected, e.g. for reasons of hygiene, from the liquid contents present in the packing container, and this is generally done by a liquid-tight strip applied to the inside. A simpler manner of achieving this protection consists in ensuring that the thermplastic layers (3, 4), which in general are present on both sides of packing laminate, extend past the cut edge (12) and are sealed in a liquid-tight manner to each other. This can be achieved simplest if the hole- punching of the carrier layer of the material is done prior to the application of the thermoplastic layers.

Abstract: A process and an apparatus for performing analyses in liquid chromatography, by means of a pump capable of drawing a fluid and injecting it at high pressure, through at least a control valve, into a separation column. To obtain maximum precision as required by the analysis, before each analysis or each group of analyses, or with respect to each fluid used, a pump stroke is performed with the pump delivery side shut off in order to record and memorize the characteristics of compressibility of the fluid. These characteristics are kept into consideration in the subsequent operative stages to obtain an exactly constant delivery of the feed pump to the separation column.

Abstract: Manufacture of arsenic acid by oxidation of arsenic trioxide with hydrogen peroxide is potentially hazardous, especially when making concentrated solutions of arsenic acid as sought by the users. The process also can suffer from substantial wasteful decomposition of hydrogen peroxide. The problems arise from or are exacerbated by the nature of the reactants, the exothermic character of the principal and decomposition reactions and the formation of localised hot spots.   The problems can be ameliorated by introducing the reagents with agitation into a body of reaction product and maintaining the reaction mixture at a temperature of not more than 70 DEG C and preferably 45 to 55 DEG C. By carrying out the process in such a manner, it can accomodate even low grade arsenic trioxide as reagent.

Abstract: A system for mixing supplemental fuel with the intake air in compression ignition engine includes a variable area venturi (16) in an engine intake air duct (26, 14) to draw controlled amounts of a pre-mixed supplemental fuel/air mixture into the main air stream in proportion to the amount of suction created downstream of the variable area venturi (16) by the engine air flow. The variable area venturi (16) creates a pressure depression proportional to the engine air flow motivating the supplemental fuel/air mixture to flow into the engine along with the main air stream at a rate related to the engine load and speed. The variable area venturi (16) includes a housing (50) having a downstream branch (32) connected to a conventional demand-type mixer (24) which is supplied with the supplemental fuel via a demand-type regulator (22), and air through a filter (53) from the atmosphere. The variable area venturi (16) is formed by a spring-loaded, normally closed flapper valve (62, 64) which variably opens in response to air drawn through the housing by the engine (12). The variable area venturi (16) thus created provides a proportional control the supplemental fuel introduced into the main air stream over a wide range or engine operating conditions with relatively small pressure drops.
