Title: Method of checking the rate of removal of pyrogenic substances, in particular viruses, from organic material
Inventor: BECKER GERHARD
IPC: A61L2/00
Filed: 1992-08-05
Abstract: In order to check the rate of removal of pyrogenic substances, in particular viruses, from organic material, the material to be purified is passed through an ultra-filter or an ultra-filtration unit whose virus-removal rate has already been determined by passing viruses of the $i(Leviviridae) family or other, comparable, small bacteriophages through the filter or filtration unit, the virus titre determined before and after the filtration operation and the virus-removal rate thus calculated. Before or after determining the virus-removal rate, a given pressure is applied to the filter or filtration unit in a gas pressure-hold test, and the decrease in pressure over a given period measured. After filtration of the biological material, the rate of virus removal by the filter is checked by repeating the pressure-hold test.

Abstract: A B S T R A C T   The filter disks (12, 13) of the filter device are provided on both sides on a filter chamber (34), which surrounds an inflow-side, closed outflow chamber (5) in circular or helical manner. For periodic cleaning purposes on each filter disk (12, 13) is provided a suction nozzle (14, 15) for filtered off solid particles, which extends over the radial width of the filter disk (12, 13). During cleaning, a drive (20, 21) rotates the outflow chamber (5) with the filter chamber (34) fixed thereto, so that the filter disks move along the suction nozzles (14, 15). In the case of a helical filter chamber (34) only one pair of suction nozzles (14, 15) is required, in that they are moved on a rod guide as a result of the rotary movement of the filter chamber (34). The rotary movement of the filter chamber (34) in one direction makes one of the filter disks (12, 13) engage with one of the suction nozzles (14, 15). In the meantime the other is closed by a check valve (45). An outwardly tapering cross-sectional shape of thefilter chamber (34) permits the engagement of the suction nozzles (14, 15) with a slight pitch of the thread shape of the filter chamber (34) or in the case of a confined arrangement of several axially juxtaposed filter chambers. Thus, no separate drive is required for moving a suction nozzle over the filter surface and, compared with its size, the filter device has a large filter surface.            (Fig. 5)

Filed: 1994-09-28
Abstract: A stabilizing system for use with a vehicle suspension which employs a first and second strap or other flexible tension member associated with and extending between opposite control arm assemblies of the suspension.  A first end of each strap is anchored to a corresponding control arm assembly.  A second end, distal the first end, of each strap is anchored to the control arm assembly distal the first end.  Each strap, alternately, weaves over and under at least two guides associated with and positioned between the path of the straps.  The guides and/or bushings associated with the anchor points may be formed of a yieldable material to provide a yieldable biasing action on the straps.  An adjustment assembly is associated with each strap to preload the associated strap to a desired tension.  The stabilizing system occupies space between the control arm assemblies and is very lightweight due to the thin belt-like characteristics of the straps.  The stabilizing system of the present invention functions to transfer forces imposed on one control assembly to the opposite control arm assembly by alternately placing an associated strap in tension or allowing the other strap to go slack.  The flexible tension members or straps are preferrably connected to the control arms at locations tending to minimize the effect of single wheel impact loads.
