Title: Filtering apparatus
Inventor: SCHLAGINHAUFEN ARTHUR
IPC: B01D29/64
Filed: 1989-12-27
Granted: 1994-09-13
Abstract: The filtering apparatus of the invention comprises a filter housing having a water inlet and a water outlet as well as a filter bell dome connected to the housing. A main filter member and thereabove a reversing flow filter member are co-axially arranged on a filter support member located in the in-terior of the filter bell dome. The filter support member is spirally movable within the filter bell dome.  Further, revers-ing flow filter member cleaning brushes and main filter member cleaning brushes are fixedly mounted in said filter bell dome. In the operating position, the passage through the reversing flow filter is obstructed such that the water to be filtered flows through the main filter member from the exterior to the interior thereof. In the backwashing position, the filter sup-port member is spirally displaced and simultaneously obstructs the direct access to the exterior of the main filter member. During the spiral motion of the filter support member, the main filter member and the reversing flow filter member are cleaned by said cleaning brushes. Thus, the main filter member and the reversing flow filter member are thouroughly cleaned in the same operation step while the supply of filtered waters is maintained during the cleaning and backwashing operation.

Title: Two catalyst stage hydrocarbon cracking process
Inventor: SAYLES SCOTT M
IPC: C10G11/18
Filed: 1990-03-06
Granted: 2000-10-03
Abstract: In a two stage catalytic cracking process a heavy cycle gas oil fraction (HCGO) nominal boiling range 600°F to 1050°F, API gravity of -10° to +10° and 65 to 95 vol% aromatics is recycled to extinction between an ebullated bed hydrocracking zone and a fluidized catalytic cracking zone to yield a liquid fuel and lighter boiling range fraction as the light fraction from each zone.      The catalyst in the fluidized catalytic cracking zone is maintained at a micro activity 68 to 72 while cracking a virgin gas oil to HCGO. HCGO is then mixed with vacuum residuum and hydrocracked in an ebullated bed reactor. The mid range fraction is recycled to the fluidized catalytic cracking zone.      The 1000°F+ fraction is blended with a fuel oil.

Title: Method and device for the saving of electrical energy for the drive of an hydraulic lift
Inventor: NAGEL HEINZ-DIETER
IPC: B66B9/04
Filed: 1993-02-05
Granted: 2003-11-25
Abstract: With this method and this device for the saving of electrical energy for the drive of an hydraulic lift, it is possible to drive the lift cage in the upward direction with practically constant power for any loading. The maximum nominal speed in upward direction is chosen for a loading which according to experience occurs most frequently. The required size of the drive is designed in accordance with this choice. The hoist speed is reduced correspondingly for higher loads and increased correspondingly for lower loads. The variable hoist speed is achieved either through an adjustable pump (8) of variable displacement volume and controlled by a pressure-regulating valve (14) or through a positive-displacement pump (28) of constant displacement volume, which pump is driven by a frequency-regulated electrical motor (31) with stepless adaptation of the rotational speed of the electrical motor (31) in dependence on the effectively present loading.
