Patent DE-3636405-A1 (DE)
Title: Magnetic rotor of a magnetic centrifugal pump (rotary pump)
Inventor: MERSCH ALFRED
IPC: H02K5/128
Filed: 1986-10-25
Abstract: Magnetic centrifugal pumps as a rule have plastic cladding, the inner rotor also being sheathed with plastic. In order to fix the magnets during the sheathing, said magnets are held by means of a metal jacket or by means of retaining brackets, or in dovetail grooves on the rotor. The relatively low transferable powers and higher production costs resulting from these measures are intended to be avoided by the novel magnetic rotor. The permanent magnets (2) of the rotor (1) are mounted on the contact surface (6) with the metal of the inner rotor (7) by means of an adhesive which is resistive to high temperatures and absorbs the load during spraying of the sheathing (4) and the centrifugal forces in operation of the pump at speeds of revolution of 3000 rpm. Such rotors are used in magnetic centrifugal pumps wherever absolute sealing to the exterior is required. <IMAGE>

Patent DE-3710188-A1 (DE)
Title: Clamped superstructure
Inventor: WIRTH ACHIM
IPC: E01B2/00
Filed: 1987-03-27
Abstract: The construction of the known "permanent way" superstructure forms is possible up to now only with the aid of elaborate construction methods. The dynamic loads on rails and vehicles as well as the environmental impact owing to structure-borne noise and airborne noise are very high in the case of these superstructure forms. The clamped superstructure for "permanent ways" is to make it possible to be able to mount superstructure constructions precisely by machine, without problems and in a very short time, and also to be able to correct, in a very short time and likewise mechanically and without problems, the track-position errors occurring in the event of ground subsidence. In the clamped superstructure, the sleeper (1) is resiliently bedded at the top and bottom, outside the supporting region of the rails (2), by shock-absorbing composite elements (3, 4) and is clamped or pre-clamped by means of a clamping-steel element (7) to the travel-way slab (6) via an anchor plate (5) located at the top, in such a way that the transverse-and longitudinal-displacement resistance owing to the thus actuated friction pressure is at least doubly ensured with respect to the maximum-occurring horizontal forces. This clamped superstructure is to a large extent environmentally friendly and permits higher traffic loads and high-speed travelling in mixed operation, while substantially reducing the dynamic loads for superstructure, substructure and vehicle. <IMAGE>

Title: Multi-step bending machine e.g. press brake
Inventor: OHASHI YOSHIHIKO
IPC: G05B19/406
Filed: 1987-06-19
Abstract: A hydraulic pump is driven by a hydraulic motor with a main cylinder hydraulically moving an apron toward a fixed apron, and a limit valve (ULV) releasing hydraulic pressure supplied from the pump to the cylinder. A feed screw is rotated by a D-axis motor, and a movable element is moved to and fro by the screw. A lever pivotally supported by a link (13) has a free end (14A) contractable with the movable apron and a second free end (14B) contactable with the limit valve. When the moable element is driven in a first direction (+) by the D-axis motor via the feed screw, the second end of the lever actuates the limit valve open to move the apron away from thefixed apron. When the movable element is driven in a second direction (-), the second end of the lever deactuating the valve is closed to move the apron toward the fixed apron. When the apron is moved close to the fixed apron for bending, the first end of the lever is brought into contact with the movable apron so that the second end of the lever is to actuate the limit valve open to move the apron away from the fixed aprong for achieving multistep bending.

Patent DE-3805272-A1 (DE)
Title: Device for determining the gross mass of rail vehicles
Inventor: RANKY PETER
IPC: G01G19/04
Filed: 1988-02-19
Abstract: The invention is based on the phenomenon that, in the web of a girder with an I-profile or similar structure, which is subjected to bending and supported on one or two supports, considerable shear forces arise, which have a constant value between the support points. The construction serving to absorb the shear forces can be the standard rail, or this purpose can be served by a girder (4) with an I-profile which is correspondingly designed from the point of view of rail safety and arranged next to the railway rail and on which the railway wheel is supported with the wheel flange. In this case, the standard railway guide rail guides the wheel pair of the railway carriage and at the same time prevents derailment. Arranged between the support points on the girders is a system of strain gauges (9), which is suitable for measuring the shear forces, from which elements a Wheatstone bridge is constructed; the bridge is fed at the input points with DC or AC voltage while an electric voltage proportional to the tension force or the wheel loading is produced at its output points. <IMAGE>
Patent DE-3808518-A1 (DE)
Title: Multiple transverse conveyor
Inventor: WALLICH ERICH
IPC: B65G47/82
Filed: 1988-03-15
Abstract: In a multiple transverse conveyor, a clearly rectangular working cycle is achieved in that the rake which bears the tubes is assigned to a transversely movable carriage and is supported by means of eccentrics which in each case are constructed and connected so as to be drivable when the end stops are reached, while the carriage is then kept stationary. At the end stops, the rake is thus brought into the raising or lowering position via the eccentrics, so that during lowering, for example, the tubes can be lowered exactly vertically into the further-processing machines, for example the embossing machine. As a result, the said further-processing machines require in each case only to be slightly opened and at the same time stopped, so that the working cycles can in total be substantially shortened. <IMAGE>

Inventor: MASSEN ROBERT PROF DR ING
IPC: G06T7/00
Filed: 1989-02-28
Abstract: Automatic optical classification of plants in which an image of each plant is produced by a colour video camera. The colour video signals emitted by the colour video camera are digitalized and classified, picture element by picture element, into predetermined colour classes associated with the image of the plant and with the image of the background. A digitized image of the plant characterized by the colour classes is stored in an image memory and evaluated by an image computer in order to classify the plant. The image of the plant is segmented from the image of the background on the basis of the membership of the picture element in the predetermined colour classes, and geometric shape features and colour features are determined from the segmented image of the plant. In addition, the height of the plant is measured, if necessary using two video cameras and a light pattern projector. The colour classifier used for the colour classification is designed so that it can learn the predetermined colour classes through being shown image sections.
