Abstract: A control device of a vehicle suspension has a suspension device mounted between a supporting vehicle structure and a vehicle part that is movably mounted. The control device includes a blocking device for blocking a compression or rebound motion occurring at the suspension device in correspondence with a blocking command transmitted to a control unit. The control unit determines a characteristic weight value for a current loading of the suspension device when the blocking command is set and stores it as a pertinent value in a memory unit. The control unit determines a value for the weight when the blocking command is reset in order to cancel a blocking of the suspension device according to the result of a comparison with the value stored in the memory unit.

Abstract: A device for edge- and surface inspection of flat objects, particularly patterned, sawn, broken, or partial wafers, and wafers of any kind on film frames, dies, displays, glass-ceramic or metal samples or batches of such materials, Die waffle packs, and multichip modules, comprises an inspection head, with an object lens and a bright field illumination unit having a light source and an optical assembly, wherein light generated by said light source is directed by said optical assembly towards said object with an angle of incidence for illuminating said object and wherein said light is reflected from said object in the direction of said object lens; and a support for supporting said object at said edge, said support having several support arms along said edge, wherein at least one of said support arms is removable from said edge while the edge is inspected in the range of said removable support arm.

Abstract: A digital method for detecting pulses of short duration. During this process, a threshold value is formed using FIR filters with the assistance of a detection method similar to one in radar technology, by means of which threshold value short pulses to be detected can be distinguished from, in contrast, long pulses. The cut-off length of the pulses to be detected can be set in further ranges by way of simple parameter changes in the circuit. An arrangement for implementing the method is also disclosed.

Abstract: The invention relates to a granulation apparatus for strand material having pull-in apparatus for gripping the strand material and transporting it to a counter knife, a knife roll cooperating with the counter knife for cutting the strand material into granulate, and a housing accomodating the pull-in apparatus, the counter knife and the knife roll, wherein a motor driving the knife roll and the pull-in apparatus is arranged beside the housing and is connected by means of a drive axle to the rotating components contained in the housing, and wherein the motor and the housing are mounted on a common support.

Abstract: A dipping process for the production of cadmium stannate layers on a substrate, preferably glass, which comprises:(a) dipping said substrate into an alcoholic solution of a reaction product containing cadmium and tin, said solution consisting essentially of compounds having hydrolyzable and pyrolyzable residues;(b) withdrawing the substrate from said solution in a humid atmosphere; and(c) gradually heating the coated substrate to 650.degree. C., whereby hydrolysis and pyrolysis removes said residues from the coated substrate to form a coated substrate in which the molar ratio Cd:Sn corresponds to that of said alcoholic dipping solution.
