    Abstract: Monochlorinated hydrocarbons of high isomeric purity are prepared by a process, which comprises: reacting a monoalcohol having an alkyl radical having from 3 to 20 carbon atoms with cyanuric chloride; and purifying the resulting monochlorinated hydrocarbon by distillation after separation of salts and washing the monochlorinated hydrocarbon with alkali. The invention relates to a process for preparing monochlorinated hydrocarbons which contain an alkyl radical having from 3 to 20 carbon atoms and have a high isomeric purity by reacting a monoalcohol having a hydrocarbon radical containing an alkyl radical having from 3 to 20 carbon atoms to which additional cycloaliphatic radicals, aryl radicals, aralkyl radicals and alkylaryl radicals may be bound with cyanuric chloride, separating off salts, washing the reaction mixture with alkali and purifying the resulting monochlorinated hydrocarbons by distillation.

    Abstract: Certain non-optical characteristics and, in particular, mechanical characteristics are not measurable in situ in the industrial production of layers using plasma-assisted reactive electron beam vaporization, particularly if high demands are made on the hardness, wear resistance and barrier action, so as to be able to reproducibly apply the layers. The values of the optical layer characteristics are to be used as a control signal. In this method, immediately after the substrate has passed through the vaporizing zone, the reflection and/or transmission and absorption capacity are measured in the wavelength range .DELTA..sub.k =150 to 800 nm and from this are determined the refractive index and optical absorption coefficient. These determined values are compared with an experimentally determined desired value. A control signal obtained therefrom, in the case of a constant reactive gas partial pressure, controls the plasma and maintains constant the optical characteristics of the layer. The method is used in the vapor-deposition of wear-resistance, hard layers or barrier layers, e.g. of metal oxide on glass, plastic and other materials, e.g. in the building industry for facade glass and in the packaging industry.

    Abstract: A device for filling prefabricated cigarette tubes, having a housing (1), a tobacco chamber (17), a trough-shaped tobacco holder (7), a compression bar (23), a stop (31) for one end of the plug of tobacco, a finger or bushing (14) on which one end of a cigarette tube can be placed and a sliding cover (11). The length of the plug of tobacco formed can be adjusted to fit cigarette tubes of different lengths by adjusting the length of the tobacco chamber (17) and the length of the compression bar (23). The invention does this by virtue of the fact that the stop (31) defining one end of the tobacco chamber is adjustable in a direction parallel to the longitudinal axis of the tobacco holder (7) and that at least two movable sections (41, 42, 43) of the compression bar, each of different length and each capable of acting as an extension to a stationary part (30) of the bar, are mounted on a rotatable component (40) whose axis of rotation (45) is parallel to the surface (44) of the compression bar.

    Abstract: A pressure filtration apparatus including an upper portion with an inflow channel and a discharge channel for the concentrate and a lower portion with a filter support and a discharge channel for the filtrate, the upper and lower portions being releaseably connectable with one another while forming a pressure space. The apparatus contains a distributor plate whose underside is disposed parallel to the upper side of the filter and snugly above the latter while forming an intervening space, and in the center of which is an opening for the concentrate discharge channel. The outer edge of the distributor plate forms a small annular opening which extends all around closely against a basically vertically interior of the pressure space. The top side of the distributor plate has a peripherally raised outer edge which while forming a narrow annular clearance extends to close up against a downwardly pointing horizontal interior wall of the upper portion. The distributor plate has an annular distributor ring surface which grows steadily deeper from the outer edge toward the center of the distributor plate and in the center has a short connecting bushing by way of which the distributor plate is secured to the upper portion and through which the discharge channel for the concentrate runs. The apparatus also includes an inflow channel which opens up in the upper portion in the region of the deepest point of the distributor ring surface above the latter, and at least along a length disposed in front of the opening determining the direction of flow of the emerging inflow current, slopes toward the horizontal at an angle of about 35.degree. to about 55.degree., preferably about 45.degree., and relative to the vertical projection of its axis runs basicaly tangentially to the vertical projection of the distributor ring surface.In preferred embodiments of the invention, the upper portion, lower portion, the distributor plate, the inflow channel, the inflow channel bushing, the filter support, the filtrate discharge channel, and the filtrate discharge bushing may be made of polytetrafluoroethylene (PTFE). If all are made of PTFE, the inflow, the concentrate and the filtrate will be in contact only with PTFE.
