Title: Arrangement for reducing memory errors of a solid-state memory, in particular an EEPROM
Inventor: HENNIG HUBERT DIPL ING
IPC: H04M1/2745
Filed: 1985-11-21
Abstract: An arrangement for reducing memory errors, in particular of an EEPROM in a telephone set, which serves for the storage of call numbers, is specified, the call numbers being written into individual submemories and read out from there. The EEPROM has a plurality of submemories per call number and an assigned flag memory location for each submemory. Upon each operation of writing in or reading out a call number, a control device cyclically reads out the flag memory locations and compares the content of the current flag memory location with the content of the preceding flag memory locations and, if they are identical, reads out the next flag memory location. If they are not identical, the call number is written into that submemory or read out from that submemory which corresponds to the current flag memory location or the preceding flag memory location, respectively. If all the flag memory locations are identical, the call number is written into the first addressed submemory or read out from the last submemory. When reading in a call number from a submemory, the control device in each case changes the content of the assigned flag memory location.

Title: Process and device for the continuous production of profiles filled with plastic foam
Inventor: BUSSMANN RUDOLF
IPC: B29C48/12
Filed: 1985-12-11
Abstract: In a process for the continuous production of profiles filled with plastic foam, first of all a closed profile sleeve is extruded in one piece. Subsequently the horizontally guided profile sleeve is cut open in the region of its upper longitudinal edge. A foam-forming plastic material is filled into the gap formed and the profile sleeve is subsequently closed. The filling of the foam-forming plastic material takes place before the complete hardening or cooling of the extruded profile sections.
Patent DE-3600422-A1 (DE)
Title: Bracelet as an item of jewellery
Inventor: POLLINGER MAX
IPC: A44C5/00
Filed: 1986-01-09
Abstract: The present invention relates to a bracelet as an item of jewellery, having two interconnected annular segments. At least one of the annular segments is designed to be hollow in the interior and is provided with a spring. In a closed position of the bracelet, in each case one end of the hollow annular segment faces one end of the other annular segment. In an open position, the two ends are shifted away from one another counter to the action of the spring to form a fitting opening. In order to make unintentional opening of such a bracelet more difficult and, at the same time, to maintain the simple putting-on and taking-off of the bracelet, provision is made for the two annular segments each to have a connecting section with the same radii of curvature and to be connected axially to one another at the connecting sections via a sliding guide in such a way that the annular segments can be rotated relative to one another about their common centre-point. The sliding guide surrounds an axial slot in the hollow annular segment, through which a slide, which is connected to the spring and is guided displaceably in the hollow annular segment, partially projects and is fastened to the other annular segment.

Title: Locking device for printed circuit boards which are to be populated automatically
Inventor: PROKASKY NORBERT
IPC: H05K13/00
Filed: 1986-03-26
Abstract: In the case of the locking device according to the invention for printed circuit boards which are to be populated automatically, the locking pins are in each case fastened to a lever which can move linearly upwards and downwards at right angles to the plane of the printed circuit board. The lever, with the locking pin, is connected to a body which can move in a housing and has a cavity in which a bent plunger can be moved in a reciprocating manner. The inclined planes which are provided within the cavity of the movable body result in the reciprocating movement, which takes place horizontally, of the bent plunger being converted into a linear movement, which runs vertically with respect to the printed circuit board, of the movable body and hence also of the locking pin.

Patent DE-3735900-A1 (DE)
Title: Method for measuring a resistance value
Inventor: BADER HEINZ DIPL ING
IPC: G01R27/14
Filed: 1987-10-23
Abstract: A method is proposed for the measurement of a resistance value, in which the voltage drop across the resistance is referred to a first zero potential, while the measuring device is referred to another zero potential. The two zero potentials are at different levels. The resistance value may be calculated by making two successive measurements, once with a supply voltage, and then by means of the voltage drop across the resistance at a voltage difference which corresponds to the difference between the two zero potentials. This method saves an additional cable connection which carries the first zero potential to the measuring device, which is referred to the second zero potential.
