Patent DE-3338319-A1 (DE)
Title: Control method for an invertor-supplied asynchronous machine, and a device for this purpose
Inventor: KAMPSCHULTE BURKHARD DR ING
IPC: H02P23/07
Filed: 1983-10-21
Abstract: A method and a device for controlling the magnetic flux of asynchronous machine (11) are proposed. The asynchronous machine (11) is used for driving a diesel-electric prime mover and is supplied with a variable voltage and frequency via a rectifier (1), a DC-voltage intermediate circuit (2) and an invertor (10). The magnetic flux is controlled by specifying suitable values for the stator frequency (f1) and the stator voltage (U1), and hence for the slip frequency (f2v) and the stator current (I1*) by means of two-dimensional characteristic transmitters (21, 22), as a function of a reference variable (W) which determines the power or the torque, and as a function of the rotation frequency (fn). When the diesel-electric prime mover is braking, braking resistors (4, 5, 6) are connected in the DC voltage intermediate circuit (2), which results in a change in the intermediate-circuit voltage (Ud). In order to keep the torque (braking torque) constant despite a falling intermediate-circuit voltage (Ud), the slip frequency is varied in inverse proportion to the square of the intermediate-circuit voltage (f2v x k1/Ud2), but limited at a maximum to the value of the pull-out slip frequency (f2k). The stator frequency (f1) is formed by adding the slip frequency to the rotation frequency (fn). The method is universally suitable for driving and braking operation. <IMAGE>

Title: Process for joining shaped parts of aluminium or aluminium alloys to shaped lead parts fitting them
Inventor: EISFELDER WALTER DIPL CHEM DR
IPC: B23K35/00
Filed: 1983-12-07
Abstract: The process for joining shaped parts of aluminium or aluminium alloys to shaped lead parts fitting them provides for first applying to the shaped aluminium part a layer, which can be wetted by soft solders, and subsequently a layer of tin or of a tin alloy and applying to the latter a coating of a soft solder flux. The shaped lead part is, with a substantially oxide-free surface, likewise coated with a soft solder flux and laminated to a solder foil of a soft solder alloy, the flux acting at the same time as an adhesive. The two shaped parts thus prepared, with their coatings are pressed together under pressure during heating to a soldering temperature of 15 to 100 DEG C above the solidus temperature of the soft solder and cooled down under pressure.

Title: Pumping and conveying device for liquids which threaten to contaminate the ground water and for cryogenic liquids
Inventor: HUESTER BERNHARD DIPL ING
IPC: B67D7/68
Filed: 1984-07-13
Abstract: In order to obtain a low and constant suction height in upright storage tanks for liquids and a reliable flowing of the liquid back into the storage tank in the event of pipeline leaks, an intermediate container (2) is arranged underneath the lid (13) of the storage tank, from which container a partial stream of liquid is sucked by means of a feed pump, the said partial stream of liquid acting as a propellent liquid to drive a liquid jet pump (6) which is arranged in the vicinity of the floor of the storage tank, sucks liquid from the storage tank (1) and feeds it together with the propellent liquid via a pressure pipe (8) into the intermediate container (2), in which the suction pipe (9, 10) and an overflow pipe (12) open. The delivery performance of the liquid jet pump (6) is significantly superior to that of the feed pump (3) which sucks up the propellent liquid. The said feed pump (3) can be connected via the suction pipe when liquid is removed, e.g. during fuelling. A pipe nozzle (11) which is connected to a suction pipe is used to fill and refill the storage tank (1). <IMAGE>

Title: Method of producing retainers for dental crowns
Inventor: KOERBER KARLHEINZ PROF DR
IPC: A61C5/77
Filed: 1984-08-25
Abstract: The invention has the object of using different re-shaping methods in order to avoid the process deficiencies and inaccuracies encountered in the customary production of dental crown retainers, and at the same time to reduce the production costs. According to the invention it is proposed to bring (preferably plane) metal foils or sheets into a mould for dental crown retainers directly on an individual model of a dental stump, for example by the deep-drawing method, in which the inner shape of the retainer corresponds to the outer shape of the dental stump. In another embodiment, re-shaping is to take place by means of a cavity which corresponds to the dental stump but is larger by the thickness of the retainer. In order to be able to provide the subsequent crown retainer with additional functional features as early as during re-shaping it is proposed that sheets and foils be used as pre-fabricated semi-finished products with thickenings, stiffenings, profiled sections and coatings for the re-shaping operation. In a further embodiment it is provided that pre-fabricated sleeve-shaped or funnel-shaped foil caps be re-shaped as the semi-finished products on the individual dental stump model or in the cavity thereof. <IMAGE>

Title: Process and device for the cleaning and surface treatment of containers
Inventor: FA DIETER KLANN VLOTHO
IPC: B08B9/08
Filed: 1984-10-29
Abstract: The invention relates to a process and a device for the all-over cleaning of containers, for example bottle crates - particularly in the foodstuffs sector and beverage industry - made of plastic or other materials. Known processes operate by passing the containers through a washing tunnel or bath in which cleaning liquid is sprayed through nozzles against the outer and inner surfaces, a spacing between the containers being used in an attempt to reach the surfaces disposed transversely to the conveying axis. The invention is based on the object of improving this cleaning, which is inadequate in substantial surface regions, to a very significant extent. The invention achieves this object according to the drawing in Fig. 1 in that, during the course of cleaning, the containers undergo one or more horizontal rotations on the conveying plane, container surfaces which were previously disposed transversely to the conveying axis being positioned parallel to the conveying axis. The process proposed according to the invention permits selective all-over cleaning and, by the elimination of the distances otherwise required between the containers, permits slower passage rates and thus more effective cleaning in washing zones of the same length. <IMAGE>
