Abstract: Shading device with a shading structure windably held on a winding shaft arranged in a vehicle-mounted receiving region with a passage through which the shading structure is pulled into a shading position or wound up into an inoperative position. The passage is closed or opened by a pivotably mounted closing part. The shading structure is provided with a profile movable along the window with the aid of a drive system to shift the shading structure between the inoperative and shading positions. The closing part is controlled by a control mechanism between closed and opening positions depending on a shifting movement of the pull-out profile. The control mechanism has a rotatable eccentric disk operatively connected to the closing part, the outer circumference of which has different control contours for reproducing the closed position and the opening position of the closing part depending on a rotational position of the disk.

Abstract: Besides the individual modules (1', 1'"), a compressed air maintenance device consisting of individual easily interchangeable modules (1), e.g. pressure regulators, oil atomisers (1'"), condensate separators (1'), in which the individual modules (1) may have emitters (8) for the actual operating status and/or predetermined limit values, also has an indicating and monitoring module (1") having optical and/or acoustic signalling devices (10) for the operational and/or fault status determined for the individual modules (1). Said signalling devices (10) can be easily coupled to the relevant emitters (8) of the modules (1). Any necessary maintenance work or operational breakdowns are thus easily recognizable.

Abstract: The invention relates to a method for preserving raw hides, skins and furskins comprising treating the hides, skins and furskins with an aqueous solution containing at least 0.1% by mass of cyanamide and, if desired, one or more members of the group consisting of polyalcohols, fungicides, sodium chloride, buffer systems possessing buffer capacity in acidic media, salts capable of acidic hydrolysis, weak acids and surface active agents.The raw hides, skins and furskins can be stored without of appearance of any sign of deterioration for at least two weeks in humid ambient conditions.

Abstract: The invention relates to a process for the production of propagating material of plants by micropropagation in sterile tissue culture which comprises(a) planting sterile shoot cuttings of plants in solid nutrient medium in a suitable flask, filling up the flask with a suitable liquid nutrient medium optionally containing a growth regulator and growing the shoots in the submersed system; thereafter(b) cutting up into pieces the ramified culture thus obtained which contains a number of lateral buds and shoots, rooting the top-end shoots and planting the same after adaptation, and subjecting the cuttings prepared from the lower and middle parts of the shoot cultures to further cultivations according to step (a);and repeating steps (a) and (b) until the desired number of top-end shoots is reached.
