Title: Installation for reuse of concrete residue - incorporates water filled through with bucket wheel rotor
Inventor: BRENNER MICHAEL
IPC: B03B5/48
Filed: 1990-07-04
Abstract: The installation is for reusing residues from concrete.  It consists of a trough which is relatively long compared with its width.  This trough has a water inlet and a water overflow outlet. A rotor (20) is mounted at one end of the trough with its axis (22) aligned with the length of the trough.  This rotor has pivoted buckets (26) attached to its rim.  The axes of rotation of these buckets (26) are parallel to the rotor axis (22).  As the rotor rotates these buckets scoop up sand and gravel from the floor of the trough and then transfer the sand and gravel to a conveyor.  The walls of the buckets (26) have narrow slits and all these slits in all the buckets (26) have the same width. USE - Reuse of concrete residue.

Patent DE-4024716-A1 (DE)
Inventor: PODLESAK HEINZ
IPC: F15B15/08
Filed: 1990-08-03
Abstract: In a fluid actuator with a slotted cylinder (1), a piston (3) is coupled to a power-output member (18) merely in such a way as to transmit axial forces. The power-output member (18) has a guide on the cylinder (1). The guide is designed in mirror image relative to a centre plane (14) through the cylinder axis (9) and the slot of the cylinder (1). On either side of the centre plane (14), the guide in each case has two guideways (11, 35 and 29, 31 and resp. 11, 36 and 30, 32). One guideway (29, 31 or 30, 32) runs at an angle to the centre plane (14) inside a sloping guide groove (27 or 28) in the cylinder (1) and is non-adjustable, while the other guideway (11, 35 or 11, 36) runs in or parallel to the outer surface (11) having the slot and at right angles to the centre plane (14) and is adjustable perpendicularly to this outer surface (11). To adjust this other guideway (11, 35 or 11, 36), a guide strip (35 or 36) adjustable by means of regulating screws (37 or 38) perpendicularly to the outer surface (11) is provided in the power-output member (18). In the guide designed in this way, faulty adjustments can easily be recognized and they cannot lead to any overloading of the connecting means (16). Expansion of the cylinder (1) caused by pressurising does not lead to jamming of the power-output member (18). Normal force loads of the power-output member (18) are transmitted free of wedge action to the cylinder (1). <IMAGE>

Title: Cleaning of waste material from building industry -  by separating fine sand before adding flocculating medium
Inventor: POS JACOBUS
IPC: B09C1/02
Filed: 1990-09-03
Abstract: Waste material produced by the building industry is cleaned in a special plant (1-15) by first adding water to it.  The mixt. of waste material and water is then passed through a separator (7) which separates the fine sand from the rest of the mixt.. A flocculating medium is then added to the mixt. and the flakes which are subsequently formed and float on the surace, are removed.  The separation of fine sand from the waste material reduces the amt. of material which has to be dumped on a refuse dump. USE/ADVANTAGE - Cleaning of waste building material enables the fine sand to be re-used.

Patent DE-4104285-A1 (DE)
Inventor: HENNINGER-GEIER WALTRAUD
IPC: B01D47/02
Filed: 1991-02-13
Abstract: The invention concerns a process and a device for cleaning gases laden with noxious substances. The gases are passed through at least one aqueous foam bath (22') mixed with a foaming agent. As the gases pass through the surface of the bath, they are entrapped, at least partly, in foam bubbles (76) and entrained by the bubbles from the surface of the bath. During transport of the bubbles, at least some of the noxious substances are adsorptively bound to the skin of the bubbles. The foam bubbles can therefore be liquefied, taking with them the bound noxious substances and releasing the at least partially purified gases. Water-insoluble noxious substances such as organic solvents, benzine or benzol can be removed almost quantitatively. To this end, the invention proposes that the foam bubbles emerging from the surface of the foam bath (22') be pressed from above against the surface of a foam-liquefying bath (36') arranged below the surface in the direction of flow, where they are liquefied. The gases released during liquefaction of the foam bubbles in the foam-liquefying bath (36') are introduced below the surface of a second foam bath downstream of the foam-liquefying bath (36'), and foam is reformed. The bath liquid from the foam-liquefying baths (36') is continuously circulated through a cleaning circuit in which the noxious substances are removed, and is returned, at least partially, in a purified state to the foam baths (22').
