Abstract: A brush device for an electric machine having at least one brush and at least one element such as a helical, scroll, or plunger spring for pressing each brush against a rotating contact element, for example a commutator. In at least one further element for example a spring tab, counteracts a lifting of each brush away from the contact element. To this end, the spring tab is inclined at an angle, as a result of which it exerts a weaker action when the brush moves in the direction toward the contact element than it does counter to this direction. As a result, the brush can be repositioned, but is prevented from lifting away from the contact element. This also reduces the danger of vibrations.

Abstract: A contact element holder, in particular a brush holder for commutator or wiper ring machines, has a carrier that can be secured to the machine housing and at least one quiver, held on the carrier and pointing toward the rotor, for displaceably receiving a contact element, and also has decoupling elements which are disposed between the carrier and the quiver. To achieve good noise decoupling of the contact element from the machine housing and, in use in a commutator machine, for assuring good commutation quality, the decoupling elements are embodied and disposed such that the at least one quiver is capable of executing only a limited rotational pivoting distance about the rotor.

Abstract: A kit for prescreening protein concentration for crystallization includes a multiplicity of vials, a multiplicity of pre-selected reagents, and a multiplicity of sample plates. The reagents and a corresponding multiplicity of samples of the protein in solutions of varying concentrations are placed on sample plates. The sample plates containing the reagents and samples are incubated. After incubation the sample plates are examined to determine which of the sample concentrations are too low and which the sample concentrations are too high. The sample concentrations that are optimal for protein crystallization are selected and used.

Abstract: The invention relates to the decoupling device for an actuator, which has a number of decoupling elements. A securing element is disposed between these decoupling elements. The actuator is fastened to the securing element. The decoupling elements rest against radial support shoulders and axial support shoulders of the securing element and a housing. These are embodied so that radial, axial, and tangential oscillations of the actuator are decoupled from the housing.

Abstract: An automated macromolecular crystallization screening system wherein a multiplicity of reagent mixes are produced. A multiplicity of analysis plates is produced utilizing the reagent mixes combined with a sample. The analysis plates are incubated to promote growth of crystals. Images of the crystals are made. The images are analyzed with regard to suitability of the crystals for analysis by x-ray crystallography. A design of reagent mixes is produced based upon the expected suitability of the crystals for analysis by x-ray crystallography. A second multiplicity of mixes of the reagent components is produced utilizing the design and a second multiplicity of reagent mixes is used for a second round of automated macromolecular crystallization screening. In one embodiment the multiplicity of reagent mixes are produced by a random selection of reagent components.
