Title: Process for burning coal in the manufacture of coal electrodes, and device for carrying out the process
Inventor: SCHOEN CHRISTIAN O
IPC: C04B41/45
Filed: 1981-09-09
Abstract: In a device for burning coal in the manufacture of coal electrodes for electric melting of metal, the coal treated with an impregnating agent is, during heating in a tightly sealed container, enveloped after a very short time, preferably immediately, by an oxygen-free heat carrier. For this purpose, an inert gas can be used which is heated up indirectly, for example by means of the flue gases of a burner, or electrically. However, the heat carrier can also be a molten, oxygen-free metal flowing through the container or even sand which is heated either indirectly in the container or passed through the container in a fluidised state by means of an inert gas.

Title: Screw connection for cores of telecommunications signal and control lines
Inventor: QUANTE HERMANN
IPC: H01R4/24
Filed: 1981-12-03
Abstract: In a screw connection for cores of telecommunications signal and control lines, a family of contact elements, located in a connection base, are provided with a threaded hole for the threaded shank of a cap screw. The ends of the cores are in each case clamped firmly, such that they conduct current, between the shank-side ledge surface of the screw cap on the one hand and an opposing bearing of the contact element, surrounding the associated threaded hole, on the other hand. For a screw connection which is easy to handle and is nevertheless reliably effective as a contact, it is proposed that the opposing bearing be constructed on the contact element from two uneven zones, which are constructed to be different from one another, specifically, on the one hand, in the region which always remains free of cores, a supporting zone with stop points for the screw cap for limiting the lower terminal end position of its ledge surface and, on the other hand, in the region holding the core end which is enveloped in insulation, a penetration zone with prong tips, which are recessed with respect to the abovementioned stop points, for penetrating the insulation sleeve to the conductor of the core. In this case, provided between the prong tips are troughs which have sufficient space to hold the existing insulating material masses of the sleeve, which on the one hand are forced from the penetrating prong tips as far as the remaining lateral material bridges in the sleeve and, on the other hand, are suspended firmly, without becoming detached, between the penetration points by means of the sleeve sections which have been left undestroyed.

Title: Method and apparatus for removing the bitter principles from bitter lupins
Inventor: HUSSMANN PETER DR
IPC: A23L11/00
Filed: 1982-01-19
Abstract: A method and apparatus for removing the bitter principles from bitter lupins for food purposes with simultaneous concentration of the bitter principles essentially consists in very finely milling the bitter lupins, preferably in a bead mill, and subsequently subjecting the milled lupins to stepwise washing and extraction on the countercurrent principle, initially with solutions of water and extractives from previously washed lupins and lastly only with water. The washed filter cake is dried and comminuted in order to be usable as human or animal food. The extract solutions are likewise dried in order to obtain the alkaloids with their concomitant substances in dried form. The apparatus for carrying out the process has an extractor and a plurality of containers which are connected together and to the extractor, where the extractor has a fine-mesh filter fabric on which the extraction mass is separated from the extract solutions. The introduction of heat is not necessary for washing out the bitter principles.

Patent DE-3224385-A1 (DE)
Title: Lossless oil return for flooded evaporator
Inventor: LETTNER JUERGEN PROF
IPC: F25B31/00
Filed: 1982-06-30
Abstract: The invention makes it possible to operate the evaporator in a flooded condition in combination with a level controller in any refrigeration system with oil-lubricated compressor and oil-soluble refrigerant, and periodically to perform the indispensable oil return without loss. For the purpose of oil return, the evaporator is taken out of operation by shutting off the refrigerant feed. The compressor continues to run and sucks refrigerant vapour from the evaporator until the refrigerant filling of the evaporator has been evaporated. At the end of the process of sucking empty, the compressor is switched off by a pressure regulator. The refrigerator oil displaced during normal operation into the evaporator collects during the process of sucking dry in the lowest place of the evaporator as pure oil or as an oil-refrigerant mixture and after the end of the process of sucking dry is fed back from there via a valve with a natural gradient to the oil sump of the compressor or to the oil collector. Since the evaporation of the refrigerant filling during the process of sucking dry occurs with entirely normal cold production in the evaporator, this kind of oil return takes place losslessly.

Title: Ignition switch with a steering lock with double locking for motor vehicles
Inventor: JUETTNER ANDREAS DIPL ING
IPC: B60R25/021
Filed: 1982-10-25
Abstract: The invention relates to an ignition switch with steering lock with double locking which can be considered as a further developed form of the solution described in the Patent Application 913/80 from the same applicant. As part of the characteristics which characterise the novelty and progressiveness of the invention, a notch in which the locking frame is arranged is made in the stator of the steering lock. By inserting the key, the locking frame can be rotated opposite to the force effect of a spring in its own plane, as a result of which the lug-like end piece of the locking frame jumps in under the locking face of the closing bolt and thus the locking is brought about/the closing bolt is locked. Compared with earlier solutions, the device according to the invention has few structural elements, it is more economical to manufacture, actuation takes place with a symmetrical key and a relatively high degree of operational reliability can be achieved.

Inventor: DOMBROWE ECKEHARD
IPC: A23N7/02
Filed: 1983-02-17
Abstract: A process and apparatus for peeling fruit and vegetable fruits by means of a heat shock treatment are described. The material to be peeled is continuously and suddenly exposed for a period of approximately one to one and a half minutes to a temperature in an order of magnitude of 500 DEG C. In a subsequent unheated, but externally insulated, region the material then has sufficient time for the peel to separate as a result of the thermal expansion occurring on heating. A brush peeling device is connected on the outlet side of the tunnel oven, by means of which brush peeling device remnants of peel still adhering are removed. A continuous peeling device is thus made possible and a significant increase in efficiency in mechanical treatment of fruit or vegetable fruits.
