Title: Supply container with a feed and distribution device
Inventor: SCHMIDT ROLF
IPC: D01G23/02
Filed: 1982-12-16
Abstract: The invention is suitable for an intermediate storage of flake-like material, such as raw wool and washed wool. A uniform utilisation of space, at the same time with a compacting of the material, is to be achieved and consequently economical stockkeeping made possible. This is achieved, according to the invention, in that in the upper region of the supply container are arranged two oppositely directed variable-speed endless conveyor bands which have drivers and are of adjustable spacing and variable inclination and/or pitch of the lower strands and which are connected functionally to a discharge cyclone. The drivers are arranged variably on the conveyor bands. The supporting rollers on the lower strand of the conveyor bands are arranged adjustably in terms of position independently of one another. Filling-level indicators monitor the feed operation and block a further supply of material when the supply container is full. Guide devices guarantee the straight run of the conveyor bands, and strippers remove adhering material. <IMAGE>

Title: Method for determining the vertical deviation with respect to a reference point of a body (missile, projectile) moving virtually linearly
Inventor: FIBICH WOLFGANG DR ING
IPC: G01P3/68
Filed: 1982-12-22
Abstract: Method for determining the vertical deviation with respect to a reference point of a body moving virtually linearly by making use of a sensor which is aligned with the reference point, detects the moving body and has an associated optical system, in particular an IR sensor, and an evaluation device downstream of the sensor. Use is made of a sensor having a detector row arranged in the Y-direction of the X-Y plane above the reference point, or of a sensor having two parallel detector rows situated in the Y-direction of the X-Y plane. The detector rows employ measurement technology to detect the passage, entry or exit of the observed flight path (trajectory) of the body through the image of the scene which surrounds the detector rows and is projected onto the detector plane. The vertical deviation of the flight path of the body relative to the reference point, and if necessary the speed of the body, is determined as a function of the arrangement of the detectors of the detector rows, of their prescribed dimensions, of the geometry of the sensor relative to the moving body, and of the focal length of the optical system of the sensor. <IMAGE>

Title: External cylindrical grinding machine
Inventor: ROSSEL HORST DIPL ING
IPC: B24B41/06
Filed: 1983-04-19
Abstract: Such a grinding machine consists of two spindle carriers, each having both a clamping device for clamping the workpiece to be machined and a shaft. Both shafts are each connected by means of a control line and a measurement line to one control unit. This control unit maintains the synchronously driven shafts at the predetermined number of revolutions. The synchronous movement of the two shafts can take place without a mechanical driving element, with the result that below the clamping device a considerable amount of free space for accommodating machine parts is available and the clamping devices can be adjusted independently of one another to accommodate different workpieces.

Title: Device for measuring pH, in particular at elevated temperatures, and method of operating said device
Inventor: LENZ EBERHARD DR
IPC: G01N27/416
Filed: 1983-04-29
Abstract: The device for measuring the pH in a liquid medium which is at a temperature, in particular, of over 100 DEG C comprises a sensor which acts as a pH electrode and is made of a material having high corrosion resistance, and a system for evaluating the measurement signal obtained using the sensor. In order to be able to measure the pH in situ regardless of the conductivity conditions in the medium even at the elevated temperatures, the invention envisages that the sensor (2) is composed at least partly of a material which is described as metallic glass, whose crystallisation temperature is substantially higher than the temperature of the liquid medium (M) and whose water absorption is to be determined as a measure of the pH by the evaluation system. The sensor (2) may be composed, in particular, of a wire or strip (3) and be surrounded by a grid-type counterelectrode (5). <IMAGE>
Patent DE-3315923-A1 (DE)
Title: Charging apparatus for batteries and the like
Inventor: GAUS HARRY DR
IPC: H02J7/00
Filed: 1983-05-02
Abstract: A charging apparatus is described for batteries and the like, which is distinguished in that it is smaller and lighter than apparatuses according to the prior art which are comparable in terms of power. This is achieved in that the charging takes place using a current which is regulated by thyristor/diode modules in accordance with the combination of a constant current/constant voltage/constant current characteristic with a power characteristic. In consequence, the use of a smaller transformer is possible than in the case of pure constant current/constant voltage/constant current charging. At the same time, it is proposed to arrange the transformer or the transformers internally on the housing walls of the charging apparatus in such a manner that these walls are used as heat sinks. In consequence, the transformers can be still further reduced in size because a certain amount of heating of these transformers can be accepted.

Title: Gripper for taking hold of containers closed with a lid and in particular having highly radioactive contents
Inventor: SCHOPPE KARL-HEINZ DIPL ING
IPC: B66C1/66
Filed: 1983-11-11
Abstract: The gripper for taking hold of a closed container having highly radioactive contents interacts with a supporting mushroom 3, arranged on the container lid, and a conical base part 4 below the supporting mushroom. Gripper claws 6 are pivotably held in radial slots in a gripper block 1. Springs 12 press them into the gripping position. When the claws slide onto the base part of the container lid, they are shifted into the expanded position, in which they are held by pivotable locking levers 13. Allocated to each locking lever is a pivotable catch lever 14 which is connected via a linkage 20 to the associated claw in such a way that the linkage, during an expanding movement of the claw, passes along an idle path 14d into an engagement position with the catch lever and, during movement of the claw into the gripping position, swings into a disengagement position with the locking lever and also releases the catch lever when the claw reaches its gripping position. To shift the claw from the gripping position into the locked expanded position it is necessary to lower the gripper twice onto the container lid. <IMAGE>

Title: Method, apparatus and circuitry for the contact-free determination of the direction and/or for the determination of the relative difference in the intensity of the occurrence of two extreme fibre orientations in paper, in particular in moving webs of paper
Inventor: HARTIG WOLFGANG DIPL PHYS DR
IPC: G01N33/34
Filed: 1984-04-11
Abstract: In a method for the contact-free determination of the direction of extreme fibre orientations in paper, in particular in moving webs of paper, and/or for the determination of the relative difference in the intensity of the occurrence of two such extreme fibre orientations, electromagnetic radiation, in particular laser radiation, roughly in the range of the visible spectrum (light) is radiated into the paper in the form of a beam which is sharply delineated at least over an angle of 180 DEG  of its cross-section. The intensity of the radiation emerging from the paper in the region of the point of irradiation on the irradiation side or the side of the paper situated opposite the irradiated side is then measured at a plurality of measurement points preset in a distributed manner over the angle mentioned and situated at a predetermined distance from the irradiation point or from the boundary line between the irradiated and unirradiated paper. The electrical measurements are then compared with one another. An apparatus for carrying out the method has a radiation source, optical means for generating a sharply focused beam and guiding the beam onto the paper to be investigated, optical means for producing an enlarged image of the irradiation point, detectors for investigating the radiation conditions in the region of the irradiation point and electrical evaluation means connected to the detectors.

IPC: B60B33/00
Filed: 1984-04-19
Abstract: Rolling device enabling rolling movements in one plane in all directions, without slippage and without resistance or irregularities, of simple design and low height, and which can be driven. This rolling device comprises at least two bodies with a spherical area (9A, 9B) in one or several parts, placed so that they can rotate on supports (12) and in which the spherical areas when placed together complement one another entirely or approximately to form the surface of a complete sphere. The spherical-zone bodies (9A, 9B) can turn around a mid-axis (y) perpendicular to their end surfaces and around a transverse axis (x) which runs through the equatorial plane of the spheres and cutting their mid-axis (y). The spherical-zone bodies (9A, 9B) may thus be driven so as to rotate around their transverse axis (x). Said rolling device can be used for moving vehicles or equipment with or without a drive. Furthermore, the device can serve as a rolling support and guide for machine parts. In addition, it can be used for the purpose of transmitting force, for example as a component in infinitely-variable drives with reversal of movement.
