  • Patent number: 8492137
    Abstract: The present invention relates to a cover for covering one or more sample(s) that are suitable to avoid or minimize evaporation and/or condensation of any vaporizable substance that may be present in the sample(s) or reaction mixture(s), in particular evaporation of substance at the fringes of a vessel or an array of vessels or condensation of a substance on the lid of a reaction vessel or a plate/block containing the sample(s) and/or a cover. This is achieved by providing a device comprising, among others, a force distribution unit that comprises at least one medium or material that is unable to withstand a static shear stress and deforms continuously under the action of a shear force.

  • Patent number: 4629142
    Abstract: A safety belt winding device has a housing with a housing bracket in which the housing can be fitted in different angular positions centrically symmetrical to the housing axis. A transmission member, which passes out of the end face of the housing centrically symmetrically to the housing axis and with centrically symmetrical mobility is intended to receive a switching movement from an actuating member in order to actuate the locking device of the safety belt winding device. The actuating member is provided in an actuating bracket which is in turn connectable to the housing of the safety belt winding device by means of centrically symmetrical connecting means. By this means the directions of belt extension and the directions in which the actuating bracket is attached become independent mutually and of the direction of the surface to which the safety belt winding device is fastened.
