Patent DE-4211467-A1 (DE)
Title: Determining spatial anisotropy state of low oriented two=axis polymeric object - using circularly-polarised light and measuring refractive index,thickness, size and spatial position of indicatrix from interference image and isochromate
Inventor: BERGNER JOACHIM
IPC: G01M11/02
Filed: 1992-04-06
Abstract: The object is illuminated with circularly polarised light using conoscopic beam guidance.  The angle between a defined direction and the axis intercept (14) connecting line (16) is determined from an interference image and the direction of a main axis of the indicatrix derived from the angle. The axis intercept distance is measured. The distance (A1,A2) is measured between at least one isochromate (15) from the axis intercept connecting line to the central normal to the connecting line.  The size and spatial position of the indicatrix are derived from the material's refractive index and thickness. USE/ADVANTAGE - E.g. for monitoring and controlling polymer processing machines with minimal equipment and minimal failure rate.

Title: Fibre optical arrangement for motor vehicle - uses reflex signals to identify stations and carry state parameter values
Inventor: JOST MICHAEL
IPC: B60R16/03
Filed: 1992-05-08
Abstract: The fibre optic arrangement includes a mechanism for generating a reflex signal with a property characteristic of subsystems connected to the arrangement at different locations in the vehicle. Optical stations located at the connected subsystems are controlled form a central point. The stations send a first reflex signal to the central controller whose starting time is a characteristic of a station. A state of the subsystem connected to the station is represented by the time interval between the first reflex signal and a subsequent second one. USE/ADVANTAGE - For detecting physical state parameters or states in subsystems of vehicle. Simple arrangement enables accurate detection of reflex signals from various locations within vehicle with low light path and analyser costs.

IPC: H01B13/00
Filed: 1992-05-09
Abstract: To produce tube-shaped mouldings out of high-temperature superconductor material based on oxides of bismuth, calcium, strontium, copper and, possibly, lead, a homogeneous melt of the oxide mixture having a predetermined stoichiometry and at temperatures of 900 to 1,300 DEG C is allowed to run into a casting zone. The casting zone rotates at 200 to 1,500 rev/min, depending on its inside diameter, around its axis, which is inclined at at least 15 DEG  to the horizontal. The solidified mouldings are removed from the casting zone and heat-treated from 4 to 150 hours at 700 to 900 DEG C in an oxygen-containing atmosphere. <IMAGE>
Patent DE-4215530-A1 (DE)
Title: Sludge drying
IPC: C02F11/13
Filed: 1992-05-12
Abstract: To dry sludge matter, it is carried by at least one continuous conveyor through a radiant heat zone which initially raises its temp. to a point where it starts to become tacky. In a second zone, the radiant heat is structured to convert the tacky condition and change the material into a loose structure which can be ejected from the conveyor.     Also claimed is an assembly with an open conveyor channel with a screw conveyor and a radiant heat assembly with at least one heat radiator, followed by a conveyor. The conveyor channel has two heating zones, with the zone change at the point where the sludge starts to become tacky. The speed of material travel, material vol. and the screw conveyor speed are structured so that the sludge remains in a suitable state to be carried by the screw conveyor. The following conveyor carries the material through a final drying stage.
Patent DE-4217292-A1 (DE)
Title: Capacitive distance measurement between workpiece and machining head e.g. of laser cutter or welding machine - comparing distance sensor signal with value derived from earlier sensor signal, e.g. formed by periodic sampling
Inventor: JAGIELLA MANFRED DIPL ING
IPC: B23K26/04
Filed: 1992-05-25
Abstract: A sensor electrode mounted on a machining head produces a sensor signal corresp. to the distance between a workpiece and the machining head. A later sensor signal value is compared with a comparison value derived from an earlier sensor signal value. A distance value corresp. to the comparison value is at least approximately maintained if the later signal is smaller than the comparison value by more than a defined amount. In other cases the later value is used to determine the distance value. ADVANTAGE - Accurate machining head to workpiece distance measurement and control are achieved even when sensor signals are subject to transient interruptions.

Title: Method and device for determining the degree of filling by means of the level or, respectively, of the level of liquid in a container
Inventor: SCHWARTING GEORG
IPC: B64D37/02
Filed: 1993-03-27
Abstract: The invention relates to a method and device for determining the degree of filling by means of the level or, respectively, of the level of liquid in a container, in particular the degree of filling of the tank. The method according to the invention is characterised in that an optical waveguide is inserted into a container, in that a defined quantity of light in the form of a light signal is transmitted through the optical waveguide, in that the transmitted light signal is received after passing through a defined optical waveguide path and in that, by means of the comparison of transmitted and received light signal, the light loss dependent on the ratio of the part of the optical waveguide path passed through wetted by the liquid and that of the unwetted part is determined, and hence the said path ratio, which allows the determination of the location of the liquid level as a boundary location between the wetted and the unwetted part of the optical waveguide.

Title: Counterflow (countercurrent)/direct heat exchanger as a preheating and/or cooling system
Inventor: DORST HELMUT DIPL ING
IPC: F28C3/14
Filed: 1993-07-23
Abstract: The static direct heat exchanger, chiefly the cyclone preheater used in larger modern systems, is contrasted with a novel heat exchanger system having more favourable specific energy consumption and a smaller overall volume. For specific cases of need, e.g. limitation of overall height, a heat exchanger which is to be operated (rotated) horizontally and has the same advantages as before is the object in question. The various grate coolers (grate-type coolers) for cooling clinker to a low final temperature of the clinker are contrasted with a tube cooler having a duotherm circuit in the case of a lower requirement for electrical work. The concept of the internal dedusting (dust collection, dust removal, dust extraction) (6) of the main application with a variety of variants of a material precipitator (separator) is used as an intermediate heat exchanger in conjunction with substantial heat recovery. This design permits multistage systems with intermediate precipitation and resupply of the material from stage to stage, as well as multistage preheating systems. The heat exchanger as preheating or/and cooling system for fine-grained or granular material is particularly suitable for cement raw meal and cement clinker.

Title: Process for producing a cover unit for vehicle roofs and cover unit for vehicle roofs
Inventor: GLATT HANSPETER
IPC: B60J10/82
Filed: 1993-08-03
Abstract: Known processes for producing cover units and cover units produced by the said process have in common that they need complex precautions for carrying out the process, producing the cover unit in one operation. These precautions are required in order to avoid deformations of the edge-gap sealing profile due to polymer flowing in. The novel process is intended to make these precautions superfluous and permit the production of a novel cover unit with a tolerance-compensating, exchangeable edge-gap sealing profile. In order to carry out the novel process for producing the novel cover unit, precautions for positioning and arresting the edge-gap sealing profile with a form fit are provided on the mould and on the edge-gap sealing profile. These precautions are provided on the edge-gap sealing profile in such a way that they are plastically deformable and consequently tolerances between cover unit and vehicle roof opening can be compensated. Production of a cover unit for vehicle roofs with a tolerance-compensating exchangeable edge-gap sealing profile in one operation.
