    摘要： For the sealing of valves or flanges, particularly used in vacuum technology, two opposed sealing surfaces are arranged at a main flange, on which a sealing element can be brought to rest, which is in the form of a cup spring and which is adjustable in the axial direction. In order to perform this operation with a smaller closing force, the cup spring is arranged in the space between the axially movable ring of a smaller diameter and a washer of greater diameter. The washer is radially outwardly and inwardly deformable, in an elastic manner, and the radial length of the cup spring is selected, so that when the seal is open, the cup spring is wedged within the space and when the seal is closed, it rests on the main flange in a nearly parallel position on a radius line with the seat of the seal.

    摘要： The present invention teaches a valve mechanism with constraint guide means. Both opening and closing of any valve working according to the principle of the invention is achieved by moving a central plate with respect to one or two plates for blocking flow through the valve. The constraint guide means according to preferred embodiments of the invention consist of grooves in the plates which cooperate with middle plate. As the grooves are inclined with respect to the direction of movement of the middle plate, a movement between these plates and the middle plate will cause opening or closing of the valve.

    摘要： 3-(2,4-Dichlorophenyl)-5-t-butyl-1,3,4-oxadiazol-2-ones of the formula: IN WHICH R represents a hydrogen atom or an alkoxy group containing one to four carbon atoms, which possess herbicidal properties, are prepared by a new process involving reaction of a halogenonitrobenzene of the formula: IN WHICH Y represents a halogen atom and R is as defined, with an alkali metal salt of 5-t-butyl-1,3,4-oxadiazol-2-one, reduction of the nitro group in the resulting 3-(2-chloro-4nitrophenyl)-5-t-butyl-1,3,4-oxadiazol-2-one, which may carry an alkoxy substituent R in the 5-position of the benzene ring, to a primary amino group, and replacement of the amino group in the resulting 3-(2-chloro-4-aminophenyl)-5-t-butyl-1,3,4-oxadiazol-2one by a chlorine atom by reaction of cuprous chloride with a diazonium salt derived from the amino compound. The process avoids the use of phosgene - an awkward reagent hitherto employed in the production of the 3-(2,4-dichlorophenyl)-5-t-butyl-1,3,4oxadiazol-2-ones.
