Abstract: A pendulum support is particularly suited for supporting an engine unit. The support has two mutually spaced-apart fixing elements for connecting two bodies that can be displaced in relation to one another. The fixing elements are elastically interconnected. The object is to provide a pendulum support with a high degree of deflection that is cost-effective to produce. The base body has two base body elements, which are interconnected by at least one elastic shear element. At least one of the base body elements is formed with a cavity, wherein one area of the other base body element is contained with a degree of deflection.

Abstract: Photoresist compositions are described, which are sufficiently transparent in the solvent-free state for radiation of a wavelength of approximately 193 nm, and which contain nonaromatic chemical groups, which can be converted into groups with aromatic structural elements (latent aromatic groups) under process conditions, for which an image structure comprised of the resist material is not disrupted.

Abstract: The present invention relates to a process for the stereolithographic preparation of a three-dimensional object, wherein the object is built in a container which contains a radiation-curable liquid formulation with fillers by a repeated alternating succession of process steps (a) and (b). In step (a), a layer of the radiation-curable liquid formulation, one limitation of which is the surface of the formulation, is cured using suitable radiation within an surface area which corresponds to the desired cross-section of the three-dimensional object to be formed at the level of this layer. In step (b), said cured layer is coated with a new layer of the radiation-curable liquid formulation. The process comprises homogenizing the radiation-curable liquid formulation continuously or discontinuously to such an extent that there is no noticeable change in the filler content of the radiation-curable liquid formulation in the area of that layer with which the cured layer is coated in step (b).

Abstract: The invention relates to a process for stabilizing a liquid radiation-curable composition comprising a cationically polymerizable compound and a photoinitiator for cationic polymerization against premature commencement of the polymerization, in which a basic ion exchanger is brought into contact with the composition, at least for a certain time. The ion exchanger is preferably removed before commencement of the radiation curing, at least from the part of the radiation-sensitive composition which comes into contact with the radiation. The process is particularly suitable for stabilizing stereolithography baths in extended use against an undesired increase in viscosity.

Abstract: A radial bearing, particularly for a torque support in motor vehicle engines, includes an outer sleeve and an inner sleeve which is coaxial with the outer sleeve and is constructed as a bush core. The inner sleeve is provided on its outer periphery with at least one radially orientated elastomeric body and at least one rubber end stop. The rubber end stop is active only after a predeterminable spring deflection of the elastomeric body. The inner sleeve also has two mutually opposite elastic carrying bodies, through which the inner sleeve is elastically mounted on the outer sleeve. If there is a radial introduction of force, three linear characteristic curve ranges with different rigidity are present one after the other.

Abstract: An engine mount includes upper and lower bearing plates and a hollow-cylindrical support spring being formed of an elastomer and being fastened between the bearing plates. A cup-shaped housing adjoins the lower bearing plate. An inner hollow chamber is defined by inner wall surfaces of the hollow-cylindrical support spring and of the cup-shaped housing. A transversely extending elastic wall divides the inner hollow chamber into an upper chamber and a lower chamber and has a periphery being clamped. A bolt extending centrally within the inner hollow chamber is joined to the upper bearing plate and to the transversely extending wall. The upper and lower chambers are filled with liquid for additional hydraulic damping, and the elastic wall has an overflow opening formed therein through which the upper and lower chambers communicate. A transversely-extending stop plate has an opening formed therein and is disposed in the cup-shaped housing.

The ratio between the concentrations of the individual photoinitiators is so adjusted that the composition has virtually the same optical density for the radiation of the different emission lines at which the photoinitiators are effective.

Abstract: An elastic bearing bush includes an outer, cylindrical bearing sleeve having an interior, an inner part, and a horizontally extending elastomer body holding the inner part in the interior. The elastomer body defines free regions in the form of circular segments acting as upper and lower fluid-filled spring deflection chambers above and below the inner part. Elastic, substantially cup-shaped stops are fixed on the bearing sleeve, are disposed inside the spring deflection chambers, protrude to the vicinity of the inner part and enclose the spring deflection chambers between the stops and the bearing sleeve. The spring deflection chambers communicate with one another through conduits.

Abstract: An electric control circuit of an electromagnetic clutch includes a relay-controlled, two-position switch which operates, in response to a power source being disconnected from the switch relay and the clutch, to establish a path to ground through which the induced voltage of the clutch may be dissipated to thereby speed up the disengagement of the clutch once power thereto is discontinued. The control circuit may be that employed in a self-propelled forage harvester equipped with a metal detector, the latter including a normally closed relay switch which opens in response to metal being sensed to thereby de-energize the clutch and two-position switch relay.
