Title: Butene poly carboxylic acid esters
IPC: C07C51/09
Filed: 1968-08-29
Abstract: Butene poly-carboxylic acid esters. .N1-. Esters of formula (I):- are prepared by reaction of acrylic compounds with ethylene dicarboxylic esters in the presence of a tertiary phosphine of phosphoramide catalyst, at 30 degrees - 120 degrees C, using an inert solvent. (X is - CN, -COOR1, -COR2 or CONR3R4; R1,R', R" are alkyl, alkenyl, aryl, alkylaryl, or cycloalkyl; R2 is H, alkyl or aryl; R3, R4 are alkyl, phenyl or together form an alkylene or oxyalkylene group with 4-5 degrees C). The esters are used for the preparation of polymers, particularly as co-polymers with styrene, acrylonitrile, vinyl acetate etc. Also used, in form of the acid anhydride, as hardeners for epoxy resins. Because of their ready tendency to decarboxylation, also used expanding mediums.

Patent NL-7016746-A (NL)
Title: Linear polyamides of high melt viscosity
IPC: C08G69/06
Filed: 1970-11-16
Abstract: Polymers are produced by ingesting a polyamide of low melt viscosity, which may contain a compound (I) which catalyses the formation of amide groups, with an organic compound (II) which is liquid at room temperature, does not dissolve the polyamide, and does not react with the terminal COOH or NH2 groups of the polyamide, followed by separating the low-viscosity polyamide. If the catalyst I is absent, the compound II is a halogenated, saturated aliphatic or aromatic hydrocarbon. Catalysts I include H3PO4, ZnCl2, DMF and NaOH. The high-viscosity polyamides show further increase in melt viscosity on standing in the molten state for short periods. The method is cheap and quick; risk of thermal degradation is reduced. Moulded or extruded articles, and tough fibres, suitable for type cords and drive belts, can be produced from the polyamides.

Title: Actuator for butterfly valve with pressurised seal - has delay means de-pressurising seal before opening and pressurising seal after closing
IPC: F16K31/12
Filed: 1975-08-12
Abstract: The actuator is intended for a valve giving gas-tight shut-off of the type having a resilient sealing element which can be inflated by means which are independent from the line medium, whereby a common control operates the valve closing and opening means as well as the mechanism to inflate the sealing element.

Abstract: The invention provides a detector for detecting air components, e.g. contaminations, and in particular noxious or poisonous contaminations, which device comprises a housing in which an air pervious carrier containing a first reagent is arranged, this detector being adapted to draw air to be tested through said carrier so as to expose this reagent to the air, this reagent being influenced by the components to be detected, which carrier is to be contacted with a second reagent which, together with the first one, can bring about a colour reaction depending on the fact whether the first reagent has been influenced or not. The housing forms, in the operative condition, an integral unit, an air- and liquid-tight container with a rupturable wall and containing a not contaminated liquid contributing to said colour reaction being arranged within said housing, the latter being, furthermore, provided with a yieldable wall portion and a plurality of piercing pins arranged in such a mutual spatial relationship that the container can be pierced by pressing inwards said wall portion, so as to moisten said reagent carrier with the liquid from said container. In particular the second reagent can be contained in a similar second carrier which is normally separated from the first one but is contacted therewith when pressing inwards said wall portion.

Abstract: The invention relates to a method for the performance within a system by a second component, at the instigation of a first component, of a computing and/or logical operation on at least one data item. Herein, the first component can perform operations on the data represented by numbers, of which the absolute value is less than a first modulus v, while results from the operations performed by this component also have an absolute value which is less than the first modulus v. The second component can perform operations on data represented by numbers, of which the absolute value is less than the second modulus w, while results from the operations performed by the second component also have an absolute value which is less than the second modulus w; herein, the first modulus v is equal to or less than the second modulus w. To verify the result of the operation performed by the second component, the first component carries out a transformation on the data affected by the operation and then performs the aforementioned operation hereon. The result thereof is compared with the operation result from the second component similarly transformed in the first component. If the results are identical, the first component adjudges the result of the operation performed by the second component to be correct.
