Title: Transport facility for transporting disabled persons in a wheelchair
Inventor: DREIER JUERGEN DIPL-ING
IPC: B66B9/08
Filed: 1986-10-25
Granted: 1987-10-15
Abstract: A lifting harness (12) is provided for lifting the wheelchair, having rigid rods (13) that pivot relative to a carriage (3), and to whose ends a carrying rod is fastened. Traction elements (49, 52) from which a wheelchair can be hung extend from the carrying rod (17). There are brakes on the carrying rod (17), which brake any pendulum motion of the wheelchair more or less strongly, depending on the loading of the suspended wheelchair. The invention has the advantage that the necessary pendulum suspension of the wheelchair does not result in any unacceptable oscillations. Yet it is possible to swing the carrying harness to the side a little when attaching the wheelchair. <IMAGE>

Title: Vertically adjustable podium, in particular scissors-type podium
IPC: E04H3/26
Filed: 1989-01-18
Granted: 1990-01-18
Abstract: A vertically adjustable podium, in particular a scissors-type podium, for stages or the like exhibits a platform. The mutually opposite platform sides are provided, on the platform underside, with latching holes for engageable and disengageable locking pins which interact with said latching holes and serve to fix the height. The locking pins can be actuated, by means of an actuating device arranged on the platform underside, in particular on diametrically opposite second platform sides. A simple construction method has been achieved in that the actuating device exhibits a drive shaft which extends between the two platform sides and is designed as a multiple-groove shaft. Arranged in a rotationally fixed manner on this drive shaft is at least one axially slideable multiple-groove hub which exhibits at least one drive lever which juts out at the periphery and is intended for actuating the locking pins.
Patent DE-3911495-C1 (DE)
Title: Hydraulic valve actuation unit for piston engines
IPC: F01L9/10
Filed: 1989-04-08
Granted: 1990-08-30
Abstract: In a hydraulic valve actuation unit, not only is the valve opening movement initiated by hydraulic medium acting on a piston, but in addition the valve closing movement. A separate preloaded helical compression spring is nevertheless provided both in the valve opening direction and in the valve closing direction. The complete system thereby forms a spring-mass oscillator. In this the hydraulic medium, with the input of energy, is transferred to and fro between a hydraulic chamber assigned to the piston triggering the valve opening movement and a hydraulic chamber assigned to the piston triggering the valve closing movement. The said measures increase the efficiency of a hydraulic valve actuation unit considerably.

Patent DE-4215339-C1 (DE)
IPC: C12M1/00
Filed: 1992-05-09
Granted: 1993-04-15
Abstract: A continuous preparation process of a sterile culture medium is universally applicable and allows a gentle treatment of the culture media in a continuous operation. The components of the culture medium are mixed before being sterilized and the thus obtained flow of medium is supplied to a transverse flow filtration module in which the medium flow is subdivided into a permeate and a retentate. The retentate is freed from germs in a centrifuge, then returned in the medium flow to the transverse flow filtration module, whereas the permeate is supplied to a bioreactor. Microorganisms are continuously ejected by the centrifuge from the retentate circuit, considerably reducing the danger of overgrowths or ingrowths on or in the filtration membrane.
