Patent DE-3302974-A1 (DE)
Title: Screw centrifuge
Inventor: JAKOBS WILLY
IPC: B04B9/00
Filed: 1983-01-29
Abstract: In most cases, the centrifuge drum and the conveyor screw in screw centrifuges are equipped with their own drive motors, and they are driven by these at different speeds via a gearbox. This drive system however requires special switchgear and is hence relatively costly in constructional design and is associated with high capital and operating costs. According to the invention, the object is therefore to improve the drive of the screw centrifuge both in constructional design and also in manner of operation. This is achieved according to the invention by a drive motor (6) with a through drive shaft (7) which is connected on one side via a reduction gear (4) to the conveyor screw (2), and which is connected on the other, opposite, side to a pump, constructed as a hydraulic control unit (8), with power controller and constant pressure controller, the said pump being connected via pressure ducts (9,10) to a hydraulic motor constructed as a hydraulic constant-displacement unit (11) and acting on the drum casing (1) via drive media (12,13). <IMAGE>

Title: Fully automatic method of rapidly, specifically and selectively determining quantitatively low-concentration substances in extremely heterogeneous substance mixtures
Inventor: KAGE ANDREAS
IPC: G01N30/88
Filed: 1983-02-18
Abstract: The system on which the method is based comprises a modular solvent purification and degassing system, a highly effective prepurification and a derivatisation system followed by a high-resolution chromotography system, and a final quantifying detector system. The entire system is synchronised by a process control system comprising two independent timing programmes, one of which controls the prepurification system and the start of the second programme, while the other controls the high-resolution chromatography system, including the detector devices. The solvent purification and degassing system is based on two liquid reservoirs which are connected via various filters and which are sealed from the atmosphere. The degassing takes place in the primary reservoir, while the secondary reservoirs contain the solvents in degassed and purified form. In the prepurification and derivatisation system, the substance mixture containing the analyte is applied to a column. Interfering substances are eliminated by "forward elution". The analyte fraction is then transferred largely selectively to a mixing section in which the medium of the analyte fraction or the analyte itself is altered in such a way that the analyte is retained on a subsequent column. After, if necessary, forward eluting interfering substances from this column, the analyte fraction is back-eluted and fed to a downstream high-resolution chromatography system. The analyte is quantified by a downstream detector system.

Abstract: The subject-matter of the application relates to a machine for machining, in particular drilling, furniture parts and for inserting fittings therein. It has at least one machining station over which at least one tool carrier can be traversed in a reciprocating manner. Several machining units or groups of machining units are arranged one behind the other on the tool carrier in the traverse direction, and the tool carrier and these machining units or groups of machining units are program-controlled in such a way that at least one furniture part is machined at the machining station during the forward motion and/or return motion of the tool carrier. In such a machine the traverse movements of the individual machining units or groups of machining units are to be separated from one another so that the units or groups of units approach the positions intended for them along the furniture part independently of one another and are each controlled independently with regard to the operation to be performed by them, whereby the machining time per furniture part can be minimised. To this end, the tool carrier is subdivided into at least two individual slide rests which can be traversed and controlled independently of one another over the machining station. A machining unit or a group of machining units is arranged on each slide rest.

Title: Device for regulating the flow rate in an air line
Inventor: SIEGWART EMIL
IPC: G05D7/01
Filed: 1983-08-20
Abstract: A device for regulating the flow rate in an air line (1) has a butterfly valve (3) which is arranged in the flow cross-section and is held by a helical spring (4) against the force exerted on it by the flow in a position more or less closing the flow cross-section. The helical spring (4) is fastened to a longitudinally displaceable and rotatable rod (7) reaching with a transverse pin (6) into the spring coils. As a mounting and adjusting means for the rod (7), a cylinder (11) is screwed to the wall (1) of the air line. The cylinder (11) is provided with a rotatable cap (12). From the cap (12), a piston (19) arranged in the cylinder (11) can be axially displaced via a screw (18) and can be rotated via the screw (18) and a pin (15). The rod (7) sits on the piston (19). The preloading of the helical spring can thus be changed by axial displacement of the piston (19), and the spring characteristic can be changed by rotating the piston (19), since, upon rotation, the rod (7) with the transverse pin (6) screws deeper into the helical spring or unscrews further from it and thus changes the number of effective spring coils. <IMAGE>
