  • Patent number: 4923305
    Abstract: A water bath shaker apparatus including a drive mechanism for producing a shaking motion and equipped with a tube for accommodating water, and a shelf having secured thereto a container of liquid to be shaken such as, for example, Erlenmeyer flasks. The tub has a filling zone for the water bath in the form of a closed ring with a central passage for the drive shaft of the drive mechanism, with the shelf being essentially constructed as a circular ring and being mounted at the upper end of the drive shaft so as to be driven by the drive shaft.

  • Patent number: 4668220
    Abstract: An infusion pump for controllable long-term injection of solutions from a syringe which can be emptied in a controlled manner for use with medical drugs in large doses. The infusion pump has a holding device for at least one syringe and an actuating device for the piston of the syringe which is connected to an electrical control drive, and an electrical battery for the drive. The actuating device is provided with a storage device for mechanical work acting through a detent member in the sense of the drive. The electrical control drive is adapted to release a retarding device when switched on, and to actuate the retarding device when switched off.

  • Patent number: 4047704
    Abstract: The shaking machine comprises a frame in the form of a base in which there is mounted a driving motor which rotates two vertically oriented shafts on which at least two supports are mounted in vertically spaced relation. Each support has two bearing bodies, each having a central bore receiving an eccentric member rotatable with a respective shaft so that, as the shafts are rotated, all points of each support execute horizontal circular movements at mutually equal velocities along paths having mutually equal radii. In one embodiment of the invention, a respective sector shape balance body is mounted for rotation, about a vertical axis at the center of gravity of the support. The eccentric secured to one shaft is in the form of a gear which is connected by a gear belt to a gear secured to rotate with the balance body. In another embodiment of the invention, each shaft has secured thereto, with respect to each support, a respective sector shape balance body.
