Title: Starch or protein prods. extrusion - with radio pressure build=up for homogeneous mixing
Inventor: SOLENTHALER KARL
IPC: A23L7/10
Filed: 1980-06-20
Abstract: Extrusion process for a prod. consisting of expanded starch prods. (maize, barley, tapioca, rice, potatoes) or of structured protein prods. (groundnuts, sunflowers, wheat gluton, leguminous plant) applies on the charge in the screw extruder a pressure, friction and heat. In a first part of the extruder, the pressure in the material is built up quickly. In a second part, most of the pressure is used up before the extrusion nozzle for mixing and homogenisation. This results in a stable flow by avoiding pressure pulsations, a narrow residence spectrum, and a high throughput for a small capital expenditure, yielding a product of better quality and constant characteristics.

Title: Ores and minerals recovered from sea-bed are conc. - by underwater flotation before delivery to ship
Inventor: ROTTENBACHER KLAUS
IPC: B03D1/14
Filed: 1980-09-24
Abstract: Ores and mineral raw materials are obtd. from seabed sediments by the flotation principle. Flotation is carried out at the site, below the water surface, the enriched material being then conveyed to the surface, while the waste residue is dumped back on the seabed. In one embodiment, the flotation is carried out in one or more flotation cells located above the sediment. In another embodiment, the flotation is carried out in an open-bottomed flotation device lowered onto the seabed. With the latter method, partly enriched material may pass to flotation cells for further enrichment. Used for the selective recovery from seabed material of metal concns. in finely layered, loose sediments. By concg. the material using the flotation principle while still below the surface, the need for flotation plant within the ship itself is eliminated and consequently the space of the ship is better utilised for concn. and transportation purposes.

Title: Precision weighing apparatus for long bar-like loads
Inventor: HONECKER SIEGFRIED DIPL ING
IPC: G01G7/04
Filed: 1981-03-14
Abstract: The invention relates to a precision weighing apparatus for long bar-like loads, especially for fuel rods of nuclear-reactor fuel elements. The aim of the invention is to reduce considerably the high production outlay necessary hitherto in known solutions, whilst at the same time maintaining a maximum measuring range. The object of the invention is, therefore, to design a precision weighing apparatus in such a way that, by an appropriate arrangement of the force-introduction means and force transducers or force-compensating systems, there is no restriction of the possible weighing range by the tare load and sources of error regarding functioning and measuring accuracy are to be minimised. The essence of the invention is to be seen in that a precision weighing apparatus is assigned only one force transducer or force-compensating system and this is coupled to a deflecting lever with a four-bar mechanism via a lever by means of a pull wire. The four-bar mechanism and the deflecting lever are in engagement with support bearings and are assigned to a weighbridge. The deadweight of the weighbridge (tare load) is constantly compensated by existing compensating weights which are arranged in the force-compensating system. <IMAGE>

Title: Hydraulic rotating piston air engine for pneumatic hydraulic energy transducers
Inventor: WILLIG KURT
IPC: F03G7/10
Filed: 1981-05-27
Abstract: This hydraulic motor is intended principally for installation in the energy transducer in the Patent Application File No. P 2940191.0, but can also be used in other areas as a hydraulic motor since it uses a very small amount of through-flowing oil. As a further development according to the invention with respect to motors previously disclosed by me, it is to be noted that the oil circulation takes place within the motor so that only sump oil has to pumped back into the pressure container. In addition, the laminas are pressed into the displacement space by a flywheel placed on top, which benefits the torque of the motor. The repositioning of the bearing disc of the rotor into the centre, with milled-out or simultaneously cast lamina shafts on both sides, is also advantageous and brings about an optimum suspension and quiet running of the rotor and the cylinder-like coating on the rotor, so that the laminas rotate without friction - wall contact - until they are taken up by the flywheel and pressed into the displacement space is also advantageous.

Title: Method and arrangement for regulating the arc length during vacuum arc melting, and for regulating the immersion depth during electroslag remelting of melting electrodes in electrometallurgical furnaces
Inventor: THOMAS FRIEDRICH-WERNER DR ING
IPC: H05B7/152
Filed: 1981-08-28
Abstract: The invention relates to a method for regulating arc length during vacuum arc melting, and for regulating the immersion depth during electroslag remelting of melting electrodes. The melting process is in this case carried out with the melting rate and the electrical melting data between the melting electrode and its opposing pole being determined continuously. The measurements are in this case compared with corresponding required values for the melting rate and for the electrical melting data. Depending on the deviations, the electrical power is regulated and the feed rate of the melting electrode is regulated. In order to achieve the object of preventing the instabilities which occur unavoidably during the remelting process and in the case of the electrical melting data being passed through to their full extent to the regulation of the electrode feed rate, it is proposed according to the invention to supply to the speed regulator a signal (which is proportional to the melt rate) as a higher-level required value, and additionally to supply the speed regulator a signal (which is proportional to the difference between the electrical melt data and its required value) as a relatively lower-level correction signal.
