Title: Method and device for producing baked goods from a mass of dough with low viscosity
Inventor: RINDERLE KARL
IPC: A21B5/02
Filed: 1985-08-20
Abstract: A description is given of a method and a device for producing baked goods from a mass of dough with low viscosity, especially for the production of waffles or wafers, in which method the mass of dough is brought in a filling station to a position between two mould halves, which are pressed against one another and form the baking moulds, and is fully baked in a baking station arranged downstream. The fully baked product is removed from the mould halves, which are situated two-dimensionally one behind the other in approximately a single plane, at least at the filling station, and are conveyed back to the filling station. The baking moulds are taken in a section of their conveying movement out of the position in which they are aligned with one another and into a position in which they are arranged with their outsides parallel to one another and perpendicular to the conveying direction. In this section, they are pushed together so that they are as close to one another as possible, but still at a distance from one another. Suitable devices are designed as circular conveyors, e.g. with a rotary drive. The smaller amount of space taken up by such devices is advantageous.

Title: PC control unit with program memory and image memory
Inventor: SCHROETER KLAUS DIPL ING
IPC: G06F9/34
Filed: 1986-06-11
Abstract: A PC control unit with a program memory and an image memory, which are connected upstream of a processing unit, for memory-optimised and time-optimised processing of 16-bit instructions, which contain the addresses for the image memory and the operation code, particularly for programmable small control units. The aim is to make better use of the required memory circuits for the program memory in relation to the memory capacity. The object, using the advantageous 16-bit word format for a PC command, without reading it in parallel from the program memory, is to retain the processing speed nevertheless. For this purpose, a first byte, which contains the address for the image memory, and a second byte, which contains the operation code, are stored in successive memory cells of a single memory circuit. Eight outputs of this program memory are connected via a first gate to the address input of the image memory, and in parallel via a second gate with seven outputs to the input of the processing unit, and one output to the control input of a selector. On the output side, the image memory is connected with a data width of 2 bits to the processing unit via the selector.

Patent DE-3627680-A1 (DE)
Title: Method for obtaining terrestrial heat
Inventor: STELLET FRANZ JOHANN
IPC: F03G4/00
Filed: 1986-08-14
Abstract: The invention relates to a method for obtaining terrestrial heat. Known methods require two boreholes which are connected in the interior of the earth by a common cavity. Water is forced in through one pipe, while hot water or steam is extracted by means of the other pipe. In this case, wash-outs occur inside the earth, and there are corresponding instances of contamination of the outflowing hot water or steam. The invention avoids these disadvantages by forming a closed circulating system for water and steam in which the steam is fed for the purpose of obtaining energy and later condensed in order to be brought by means of a pump to the pressure required for forcing it in. A heating-up container, which is connected to the interior of the earth by thermal conduction, is located in the interior of the earth inside the pipework system.

Title: Process and equipment for controlling the corrosion protection and/or the mechanical cleaning of heat exchanger pipes
Inventor: CZOLKOSS WOLFGANG DIPL ING
IPC: F28B11/00
Filed: 1987-02-19
Abstract: The invention relates to a process as well as equipment for controlling the corrosion protection and the mechanical cleaning of heat exchanger pipes produced by cleaning elements. The frequently nonuniform flow of the coolant through the condenser pipes and the resulting nonuniform contamination are measured in randomly selected pipes by determining the heat transfer coefficient in the measured pipe from the steam in the coolant. After this measurement the cleaning takes place with the cleaning elements. If the cover layers which protect against corrosion are attacked or damaged, chemical corrosion protection or electrical corrosion protection can be produced specifically or generally. The duration and intensity of this corrosion protection in turn depends upon the measurement of the potential resistance in the measured pipe.

Title: Process for producing extruded plastic products, in particular plastic pipes
Inventor: HUNDHAUSEN FRITZ-WALTER
IPC: B29C48/08
Filed: 1987-03-28
Abstract: In plastics processing, in particular in film production, large amounts of nonreclaimable plastic residues or film residues occur. It has hitherto not been possible to reprocess these in an efficient way. The invention now proposes a process which makes possible a reprocessing of such (film) plastic residues. In the process according to the invention, a mixture of extremely finely ground plastics material (regrind) is fed to an extruder. By virtue of the extremely fine grinding and the subsequent mixing of the regrind from different batches, a free-flowing regrind with a specific bulk density is obtained, which can be processed virtually as (virgin) granules. The process according to the invention is suitable in particular for reprocessing rigid polyvinylchloride residues, such as occur in film production. Plastic pipes can be especially readily produced from the regrind produced therefrom.
