Title: Method for dispersing liquids, suspensions and heterogeneous fluids, and stirring and gas admixture system for implementing the method
Inventor: HABELSKI NORBERT DR ING
IPC: B01F7/00
Filed: 1993-02-17
Abstract: The invention relates to a method for dispersing liquids, suspensions and heterogeneous fluids which is distinguished, in particular, by more efficient dispersion of the gas to be introduced into the medium and by better distribution of the gas phase in the reaction vessel, more effective flow prevailing through problem zones. The dispersion process essentially takes place in two stages. The invention further relates to a stirring and gas admixture system by means of which the method is implemented and is intended, in particular, to be used in aeration tanks for aerating waste water and sewage sludges, with the purpose of improving the efficiency of such plants. A stirring body, open at the bottom, is preferably arranged centrally in a reaction tank below the liquid level on a drive shaft and rotates. Below the stirring body there is a gas cushion which is supplied via the drive shaft, fashioned as a tubular shaft, or is supplied separately. The stirring body is of perforated construction, the design of the perforation being capable of being varied in terms of type, size and density, and carries transport blades (paddles) on its rim. Dispersion takes place at the perforation and at the stirring-body rim. <IMAGE>

Abstract: The invention relates to a controllable drive unit for a drive device, comprising an internal combustion engine (VM) and a prime mover (AM) which is driven thereby, the drive power being controlled in relation to a prescribed desired value for a control variable in the working method by means of an actual value measurement sensor (M1) for the control variable. For this purpose, the respective power requirement is determined in each case from a difference in the measured actual value (IW) and from the parameters (PW) which influence the control variable and are continuously measured with corresponding parameter value measurement sensors (M2), and from power-requirement coefficients assigned to these measured values. By means of a control device (ST), an optimum desired engine speed is then determined, the said optimum desired engine speed then being fed to an engine speed final control element (DRS) of the internal combustion engine (VM). An electric three-phase generator (G) which feeds electrical consumers (V1, V2) via at least one converter circuit (UF1, UF2) is coupled to the internal combustion engine (VM).   <IMAGE>

Title: Bipolar coagulation tongs with automatic current switch
Inventor: ROOS EBERHARD
IPC: A61B18/14
Filed: 1994-05-10
Abstract: The tongs comprise contact springs (12,15) which do not touch the contacts (1a,2a) in a non-operating position caused by the spiral spring (19,21) pressure acting in a proximal direction. As a result, the operating parts (1,2) coming into contact with the tissue are currentless and no sensor current can flow for a starter mechanism. Extra pressure on the back handle (11) causes the unit consisting of a back slide tube (10), back handle (18), an insulator (13) with the contact springs, and the insulating sleeve (14) to move longitudinally. Each long and short contact spring touches its contact and causes current to flow from one operating part to the other through the intermediate tissue being coagulated.

Patent DE-4424760-A1 (DE)
Title: Method of treating surfaces or boundary layers by resistance heating
Inventor: SITTE GERNOT
IPC: B23K11/00
Filed: 1994-07-04
Abstract: Known methods of treating surfaces or boundary layers or of reinforcing boundary layers of cylindrical or flat components made of low-melting-point materials, e.g. aluminium, have the disadvantage that, on account of non-continuous heating of the members to be joined, the formation of the joint is adversely affected, and the usable grain size of the metal powder, the possible reinforcement layer thickness and the working speed are limited. The solution according to the invention is intended to provide a method which, in the reinforcing of boundary layers of low-melting-point materials, permits a continuous input of heat, a lower total quantity of heat, the use of larger grain sizes and thus greater layer thicknesses. This is achieved by a pulse-shaped direct current being used, preferably with a current rise. An electrode force FE (4) is superimposed with a certain program on this welding current IS (3) in a synchronized manner. An advantageous combination of welding current IS (3) and electrode force FE (4) leads to boundary-layer reinforcements of greater reliability and with greater layer thickness on components being possible on low-melting-point and other critical metals (Fig. 2). <IMAGE>

Title: Method of controlling the force on a resistance welding terminal or the like; and resistance welding machine making use of this method
Inventor: BOYER JEAN-NOEL
IPC: B23K11/25
Filed: 1994-09-13
Abstract: Method of controlling the force of a resistance welding terminal or machine which is equipped with a numerically controlled electric motor or the like. This method is characterised in that an inherent elasticity characteristic of the frame of the machine is established by allowing the motor M to exert two different forces F1, F2 on the workpieces and plotting its corresponding angles of rotation  THETA 1,  THETA 2, by means of which a clear relationship is established between each desired force F during a certain phase of the relevant process and the corresponding angle of rotation  THETA  which is to be performed by the motor M, as a result of which it is possible to vary the force during the phases "welding" and "holding after the welding". An elastic intermediate piece 14 can be inserted into the frame of the machine. Used on resistance welding machines with electrodes driven by electric motor. <IMAGE>
