Title: Process for removing paint layers
Inventor: BURKE THOMAS WILLARD
IPC: B05D5/00
Filed: 1984-10-02
Abstract: The removal of paint layers from a holding device for a product after application of the product paint is improved by using the sort of holding device which has a critical surface tension, so that a paint adhering to this surface easily breaks and is detached when treated with a low-temperature coolant. After treatment with the low-temperature coolant, the paint is removed from the holding device by means of non-metallic solids not based on silica or by means of gas or a liquid, which exert a sufficient force for effective removal of the paint.

Patent DE-3441252-A1 (DE)
Title: Certificate printer, especially a ticket printer
Inventor: HASELOFF FRITZ
IPC: G07B1/00
Filed: 1984-11-12
Abstract: In order to print the tickets, railways use mechanical apparatuses at the interface between the printing and calculating machines. Recently, VDU systems have been introduced as ticket printers, but these have not speeded up the process of selling tickets. The systems are fitted together in bits and pieces and the writing on the monitor, which tires the eyes, is hazardous. The problem is data acquisition. In this context, everything is difficult, firstly the reference books for the reference number of the station and then keying in the same (address). This time which is lost, in conjunction with errors, results in queues in front of the kiosks. The present invention remedies the defects. The ticket printer receives a clear display panel for the destination stations, which panel consists of rows and columns. Associated with each station location is a plug socket which, via a printed circuit, has access to a data-processing system. Once a plug-in pin has been inserted into a plug socket, the reference number is localised directly without any manual selection. Once the class and type have been entered, the start key is pushed. The ticket printer consists of the display board, a magnetic-disk system or a floppy-disk drive, a price file and a dot-matrix printer, or of an additional multiplexer. <IMAGE>

Title: Device for controlling the hydraulic pressure for a hydraulically actuatable manual shift transmission
Inventor: MAEDA FUJI
IPC: F16H61/06
Filed: 1984-11-15
Abstract: Device for controlling the hydraulic pressure for a hydraulically actuated manual shift transmission, which has a group of main clutches, a group of shifting clutches and a clutch for reverse running. The clutches are connected to a hydraulic pressure source by way of a number of selector slide valves and a pressure rise delay slide valve, so that for forwards or reverse travel of a vehicle or for shifting the gears, a main clutch together with one of the shift clutches or the clutch for reverse running can be respectively actuated. According to the invention a pressure relief slide valve is arranged in a hydraulic pressure circuit between the pressure source and the pressure rise delay slide valve, and a selector slide valve, arranged initially next to the delay slide valve in a hydraulic pressure circuit connecting the pressure rise delay slide valve to the clutches, has, at a point corresponding to its unactuated position, a passage for the feeding of a servo-circuit for the actuation of the pressure relief slide valve by means of pressure medium fed in by way of the delay slide valve, and at a point corresponding to its actuating position, a return passage for pressure relief of the servo-circuit.

Title: Process and apparatus for the dry fractionation of fats and oils
Inventor: STOEVER HANS-MARTIN DIPL ING
IPC: C11B7/00
Filed: 1984-12-06
Abstract: In the process for the dry fractionation of natural purified fats and oils, the molten fat or the liquid oil is cooled, whereupon the stearin crystallises out, and subsequently the liquid olein is filtered off from the stearin crystals, the filtration process being assisted by applying a pressure and connecting to a vacuum. In this process, the crystal suspension is placed on a vacuum belt filter (7), and a crystal filter cake (17a) which is 5 to 50 mm high is generated. Subsequently, the filter cake (17b) on the filter cloth (19) is sucked dry for 1 to 10 minutes by the vacuum which is applied, and a pressure of 0.5 to 10 bar is continuously applied in 1 to 10 minutes to the filter cake (17c) which has been sucked dry. An apparatus for carrying out the process is also described. <IMAGE>

Title: Device for mixing ink and surface-coating agent suspensions in printing systems
Inventor: MELNITZKI ARTHUR
IPC: B41J2/195
Filed: 1985-03-08
Abstract: Previously, there was no method available for preventing ink and surface-coating agent suspensions in printers from settling. According to the invention, this problem is solved in that one or more oscillating quartz crystals are attached to the ink reservoir container and/or to the capillaries and to the printing channels. As a result, it is ensured that the pigments remain in suspension and inks which do not always dissolve entirely are gradually completely dissolved by the oscillations.

Title: Absorber rod drive system for nuclear reactors
IPC: G21C7/16
Filed: 1985-04-16
Abstract: The invention relates to an absorber rod drive system for nuclear reactors, in particular for boiling water reactors, in which for the purpose of accommodating all the elongated parts of the drive use is made of a housing tube which can be mounted both from above and from below and is, if required, fastened via connecting elements to an adaptor member, which is connected to the drive housing, or to the drive housing itself, and to which the absorber rod guide tube located in the reactor pressure vessel can be coupled, it being the case that in conjunction with the relatively large annular gap there are located between the housing tube and the drive housing both a position display device for the hollow piston and, additionally in the special case, a coupling device for the absorber rod guide tube, and that the individual tanks, which are associated with the absorber rod drive, are filled with water and gas and are connected to one another, are connected via a pipeline, which can contain a sliding pressure control, to an additional pressure system, which is similar at least for two absorber rod drives. The invention permits absorber rod drives which are known to be functioning discontinuously to be exchanged optimally with a continuously functioning type of drive, and can also be recommended for absorber rod drive systems that are to be designed anew.
