Abstract: A system for coating objects, comprising a coating booth and an electrostatically operating separation unit. A feeding device, by which deposition liquid can be fed to the upper region of each deposition surface, is assigned to each deposition electrode of the deposition unit. The feeding device has a feed channel which can be filled with deposition liquid and which in the lower region thereof is formed by two spring plates. Two slide plates are also seated against the opposite deposition surfaces of the deposition electrode and can be moved back and forth between a position in which the lower edges of said slide plates are located above the lower edges of the spring plates and a position in which the lower edges of said slide plates are located below the lower edges of the spring plates.

Abstract: The invention relates to a device for hardening a coating of an object, more particularly a car body (12), said coating consisting of UV paint, a thermally hardening paint or the like. The device comprises at least one radiator (58, 60a, 60b, 62a, 62b) producing electromagnetic radiation. A conveyor system (14, 16, 46) that moves the object (12) to the proximity of the radiator (58, 60a, 60b, 62a, 62b) and moves it away from said radiator is also provided. The conveyor system (14, 16) comprises a lifting car (46; 461) with a running gear (50) having a lift platform (54) for receiving the object (12), whose height relative to the running gear (50) can be adjusted by means of a motor. The at least one radiator (58, 60a, 60b, 62a, 62b) is arranged in such a manner that the lifting car (46; 461) and the object (12) located thereon can be guided through under the at least one radiator (58, 60a, 60b, 62a, 62b), wherein the vertical position of the object (12) can be changed.

Abstract: The measuring arrangement consists of successive workstations which comprise a stock of paper samples, a balance, a mechanized moistening means for the sample and a blotting means, likewise mechanized, for the moistened sample. An industrial robot controllable by a program and equipped with a gripping apparatus is provided for carrying out the measurement. This arrangement determines the liquid absorbed by paper using the Cobb method and permits the measuring method to be carried out in a fully mechanized manner.

Abstract: To be able to handle minute quantities of liquid mercury or liquid mercury lloy, for example to introduce said minute quantities into the discharge vessel of a discharge lamp, a retention body in form of a pill or pellet is formed which is a porous of a metal or mixture of metals or metal alloys which have a melting point above 250.degree. C., are not wetted by mercury, and do not form an alloy with mercury. To make such a body which, for example, is made of iron, iron and copper--to reduce oxidation, nickel and copper or iron, chromium and possibly also nickel, a metal salt of the respective metal is electrolytically enriched with mercury to form a mercury--metal suspension; in case of several metals, the suspensions are mixed, coated with aqueous-free glycerine, tempered, washed, dried, non-absorbed mercury is filtered off, and the resulting filter cake is pressed out at high pressure, of 5 to 60.multidot.10.sup.7 Pascal; the brittle pressed body is pulverized and pellets of dimensions of about 1.

Abstract: A granular bleaching activator for use in a detergent or bleach, which has particles which have a size of from 0.5 to 3 mm and are composed of(a) from 70 to 99.5% by weight of one or more bleaching activators for per-compounds and(b) from 0.5 to 30% by weight of one or more water-swellable assistantsand which have been prepared, without use of water, by compacting the components (a) and (b).
