Abstract: ABSTRACT     A pressure diffuser for paper pulp includes a vertical pressurizable liquid-tight vessel having a pulp inlet at the bottom and a pulp outlet at the top.  One or more ring shaped screen elements, providing first and second concentric screen surfaces, are vertically mounted within the vessel.          A number of radially extending header arms mount the screen elements for movement in the vessel and in fluid communication with it.  A first linear actuator effects reciprocation of the arms.  A cylinder, open at both ends, is affixed to the arms and extends both above and below them, and a piston is disposed within the cylinder, below the arms.  A second linear actuator is operatively connected to the piston to effect reciprocation of the piston in the cylinder.          A guiding conduit surrounds the open end of the cylinder above the arms and guides reciprocation of the cylinder and transports liquid from the arms to an effluent outlet.  A perforated jacket surrounding the guiding conduit, nozzles at the vessel wall, and the like introduce liquid into the vessel for treatment of the pulp.  The ring shaped screen element is connected to the arms in a manner to allow the best liquid communication between them.  In this way pulp can be effectively treated in a pressurized vessel while the screens for treating the pulp are periodically backflushed without causing a surge within the vessel.

Title: Intelligent control of motor vehicle gas equipment
Inventor: VAN DER WEIDE JOUKE
IPC: F02M21/02
Filed: 1989-06-14
Granted: 1994-11-22
Abstract: Device  for  the  intelligent  control of a venturi-type car-burettor unit for a gaseous fuel, including a pressure regulator, a main  throttle valve  in  the  airsuction  pipe for control of the engine output and a regulating valve in the  gassupply pipe between the pressure regulator and the venturi, said valve being coupled to the main throttle valve.      By adjusting this mechanical system for providing a  too rich air-fuel-mixture  under  all  conditions, only minor adjustments of the mixture are necessary  to provide  the engine  with the correct mixture required  for each  load/speed condition. Said requirements are stored in a  processor, and  the latter  controls the necessary corrections  of  the  mixture  by  diluting the gasflow to the main venturi with some air. To this end a small venturi is placed in the gaspipe, the  gasflow sucking the diluting air through a mixing air regulating valve, which valve is controlled  by the  processor in a continuous,  analogues  intelligent  way.  Optionally  an O2-sensor placed in the exhaust gases may  send feed-backsignals  to the pro-cessor for last corrections.

Abstract: ABSTRACT A stone lifter serves for the extraction of large stones from a ground surface or just below the ground surface. The lifter has two arms that are mounted on a transverse tube. The lifter is mounted on a 3-point hitch of an agricultural tractor, with the hitch attachment points being connected to the ends of the tube and the upper ends of the arms. When connected, the arms slope downwardly and away from the tractor. In use, the arms are pushed into the ground beside and below the stone to be removed. The tractor is driven in reverse and simultaneously the 3-point hitch is used to lift the arms, so that the stone is simultaneously pushed and lifted out of the ground by the arms of the lifter.

Title: Folding door with several pairs of leaves
Inventor: BEHRING REINHARD
IPC: E06B3/48
Filed: 1989-07-25
Granted: 1993-03-23
Abstract: ABSTRACT         A folding door has plural pairs of panels and the panels of each pair are pivotally connected to one another via hinges defining vertical pivot axes.  For any two neighboring pairs, a first panel of one pair and an adjacent second panel of the other pair are articulated to a carrier movable along a horizontal guide rail.  At least each first panel supports an elongated actuating element having a projecting portion which overlies the adjacent second panel in the closed position of the door.  Every carrier supports a two-armed lever which is rotatable on an axis paralleling the pivot  axes defined by the hinges.  In the closed position of the door, a first arm of each lever, is located in the path which the projecting portion of the respective actuating element follows during opening of the door while the second arm abuts the respective second panel.  When one pair of panels is folded in order to open the door, the projecting portion of the corresponding actuating element pushes against the first arm of the associated two-armed lever.  This causes the second arm of the lever to push against the second panel of the pair of panels adjoining the folded pair thereby facilitating folding the adjoining pair.

Abstract: A customized album recording system under the control of a central microprocessor or mini-computer. A mater library or storage medium is filled with a repertoire of recorded information items (such as musical selections) which may originate with any suitable source, such as phonograph records, tapes, sound tracks, compact discs, or the like. Each information item is stored in the library under its own address. On read out, an operator keys in the addresses identifying the selected items which are read out of the library medium and stored in a large capacity memory, usually to provide about forty-five minutes of total listening time. Then, all of the music is read out of that large capacity memory and recorded at a high speed onto a suitable album size medium, such as a tape cassette, for example. The source music and the customized album music are usually recorded in an analog form. The music which is processed within the system is in a digital form. Thus, the various transfers of music from the master storage to the recorded album, may be accomplished at a high speed of digital transmission.      In an alternative embodiment, instead of reading out an entire album amount of recorded information items, the central computer successively reads out limited amounts of data on a demand and fetch basis. A computer provides both the analog-to-digital and the digital-to-analog conversions in order to improve fidelity.
