Patent DE-3707722-A1 (DE)
Title: Rotor pump, especially for pumping liquids containing solids
Inventor: BOERGER ALOIS
IPC: F04C2/12
Filed: 1987-03-11
Abstract: In known rotor pumps, sealing strips of plastic or rubber located at the outer ends of the displacing lobes are subject to high mechanical stresses and wear. Thus such pumps require much work to maintain and often need repairing. The novel rotor pump is intended to be more reliable and easier to maintain. The novel rotor pump is characterised by connecting means acting in a radial direction that connect the plastic or rubber strips detachably to the outer end of the displacing lobes. What is achieved in particular by this is that when the rotors rotate, no gaps can open between the strip and the outer end of the lobe on the forward side of the lobes. Thus penetration by solid particles is prevented and the service life of the rotors extended. The pump is particularly suitable for pumping liquid manure, sewage sludge, mortar and similar solids-laden liquids. <IMAGE>

Title: Extrusion die for extruding a web of foamed thermoplastic
Inventor: REIFENHAEUSER HANS
IPC: B29C48/08
Filed: 1987-03-21
Abstract: Extrusion die connectable to an extruder for extruding a web of foamed thermoplastic in the course of the production of foam mats and foam slabs with a die block and a torpedo arranged therein. The die block is provided with an inlet channel, two feed channels connected thereto and transverse-spreading gap-chambers connected to said feed channels and an outlet channel. The torpedo has a fastening region and a guide region. It is arranged in the mould block in the flow direction of the thermoplasticated plastic, downstream of the inlet channel. With its guide region, it separates the two feed channels and the two transverse-spreading gap-chambers and projects with a sword-part into the outlet channel, forming an outlet gap, where it terminates upstream of the orifice, leaving free an internal expansion chamber. The torpedo is designed without spider legs and is held in the fastening region clamped from above and below. The thermoplasticated plastic can also flow around the sword-part of the torpedo, at its end faces running in the flow direction. At least the sword-part has a temperature-control bore system which is distributed across its length and width and is connected, upstream of the sword-part in the flow direction, to lateral connection bores for the feed and removal of the temperature-control medium. <IMAGE>

Title: Bracket for suspending panel radiators, in particular those having two radiator panels
Inventor: HEUEL WILHELM
IPC: F24D19/02
Filed: 1987-03-28
Abstract: Suspension brackets which are fixedly welded to the panel radiator are troublesome as regards stacking and transportation and can damage neighbouring, ready-painted radiators in these cases. To provide a suspension bracket (7) which is fixed to the panel radiator only at the building site, there is provided a component which locks into place in at least one opening, e.g. bore (6) in at least one of the regions (5) of the radiator panel (1) welded flat one on top of the other or in at least one convection rib, in such a way that it no longer comes off by itself. The novel suspension bracket (7) also saves costs in terms of wall-fastening means, since it can be dimensioned in accordance with the desired wall spacing, so that the fastening means (screws, plugs) do not need to protrude so far out of the wall. <IMAGE>

Title: Method for determining the fundamental mode reactive power of an R-L load
Inventor: HOFFMANN REINHARD DIPL ING
IPC: G01R21/00
Filed: 1987-08-08
Abstract: In a method for the determination of the fundamental load reactive power of an R-L load controlled by means of an AC current controller (control angle  alpha ), e.g. a resistance welding machine, the intention is for the reactive power measurement to be made without integration time (delay-free). This is achieved in that the peak current value îL is measured, that the following two families of characteristic curves are already previously calculated and stored:   (1) load angle  phi L as a function of the control angle  alpha  and the phase position  alpha S of the peak current value îL (Fig. 1) (2) relative fundamental mode reactive power Q1/Smax as a function of the control angle  alpha  and the load angle  phi L (Fig. 2) and that the control angle  alpha  at the start of current flow is measured and then the relative fundamental mode reactive power Q1/Smax for this control angle  alpha  and for a previously known load angle  phi L, which is yielded by the family of characteristic curves (1) for this control angle is obtained from the family of characteristic curves (2), the multiplication of the relative reactive power with a predetermined reference power Smax yielding the fundamental mode reactive power Q1. <IMAGE>

Title: Hand-held electric tool with drive spindle driven via a two- or multi-step reduction gearing
Inventor: PREIS ERICH
IPC: B25F5/00
Filed: 1987-10-28
Abstract: In the use of electric tools, the problem frequently occurs that the torque required in a specific operating state at the tool spindle is no longer available. An example which may be mentioned is the tightening of a screw or the loosening of a tight-fitting screw. The new measure makes it possible to increase in a simple way the torque of the tool spindle, if necessary. To adjust the speed and the tool-spindle torque corresponding thereto, the tool spindle (23) can be adjusted against the force of a restoring spring (26) axially by the amount corresponding to a distance which eliminates at least one gearing step. <IMAGE>
