Abstract: An optoelectronic sensor for detecting objects in a detection zone is provided that comprises a light reception element for generating a received signal from light that is incident on the light reception element from the detection zone, a display device for highlighting the location of the detection zone for the human eye by a light pattern projected into the detection zone, and a control and evaluation unit for evaluating the received signal, In this respect, the light pattern has at least two partial patterns that are projected from different sources and that together mark a center of the detection zone independently of a distance into which the light pattern is projected into the detection zone.

Abstract: The invention relates to a new method for combating tumor illnesses through the use of molecular biological associations during formation of the tumor. The aim of the invention is to develop a method for controlling the regulation of ?-catenine in body cells. The object of the invention is a new protein which bonds to ?-catenine and the subsequent cytoplasmic decomposition of said protein. This protein has the amino-acid sequence according to FIG. 1 and is designated as conductine. Agents for diagnosing and treating tumor illnesses are developed from the occurrence and the action of conductine in body cells.

Abstract: A safety lock out switch system for the prevention of an unexpected restart of an electrically powered machine in whose main power circuit it is installed. Therein the power-free status of the power supply output of the system is confirmed visually. The system is configured so it is flexible, thus being able to be used in the most various types or sizes of machines. Technical aspects and safety aspects were taken into account therein so that the installation can be carried out in practically every country in the world.
