Title: Sucking liq. through conical bag filter wall - permits downward displacement of deposited solids towards sump by descending liq. streams
Inventor: KONZ DIETER
IPC: B01D29/11
Filed: 1989-10-31
Abstract: In the purificn. of liq. charged with solids, esp. of varying particle sizes, an inlet pipe delivers the liq. into an apertured distribution pipe round the head of a downwardly tapering bag filter terminating above the floor of an enclosed housing. A suction pump coupled to the housing floor produces an adjustable suction outside the bag, which draws liq. through the bag wall, leaving collected solids. The solids are swilled downwards by descending streams of incoming liq. largely cleaning the internal bag wall, with solids collecting near the filter tip. Filtered liq. collects above the housing floor. USE/ADVANTAGE - Suitable for removing photo-foil laminate particles with sizes 5 microns or more, using a nylon-fabric bag. Constant floating off of collected particles prolongs service life before clogging.

Inventor: ERIKSSON AAKE
IPC: D03D49/54
Filed: 1989-11-09
Abstract: The shuttle is braked in the shuttle-checking device which is provided with a damping mechanism with which the shuttle engages and is thus braked.

Title: Method and module for controlling the height of a vehicle
Inventor: MINE ATSUSHI
IPC: B60G17/0165
Filed: 1990-02-03
Abstract: In a motor vehicle with a vehicle height adjusting device (A, B, C, D, E, F, G; 2a, 2b, 2c, 2d; 3), which controls the height of each suspension so that a set vehicle reference height is maintained, the reaction forces of the respective suspensions (1a, 1b, 1c, 1d) are in each case determined (at 16) and a difference between the detected reaction forces is calculated according to an equation, for a vehicle condition in which the vehicle is stationary or running straight. Should the calculated difference exceed a predetermined value, this is interpreted as signifying that contact stressing of the wheels occurs in the event of imbalances of the road surfaces. Once imbalances have been detected, the vehicle reference height is increased for some suspensions and reduced for other suspensions in such a way that the imbalances are eliminated. In a special case the imbalances are detected when a value, obtained by a formula, including the integrated values for the suspensions, exceeds a predetermined value. <IMAGE>
