Abstract: The present invention relates to a system of tensioning for strung sports equipment like tennis racquets with adjustable string tension in which some of the strings are connected to the tensioning mechanism as "primary string sections" while the rest, as "secondary string sections", are only indirectly connected to the tensioning mechanism via the primary string sections. The arrangement of the primary and secondary string sections means that a ball striking any part of the surface contacts the same number of primary and secondary string sections.

Title: Heat and power machine - uses temp. differences to convert thermic energy into mechanical energy
Inventor: BODEWIGS PETER
IPC: H02N10/00
Filed: 1992-09-22
Abstract: The heat power machine comprises a rotor (2) made of a Curie metal alloy, which rotates in a magnetic field (1). The rotor is exposed to a temp. difference, which causes it to exceed the Curie temp. in the area of heat absorption and so to lose the ferro-magnetism, and in that area a static magnetic field is arranged, which permanently attracts the part of the rotor which is still ferromagnetic.This causes the rotor to execute a continuous rotary movement, and as a result of a circulation with renewed approach to the magnetic field the rotor recovers its ferromagnetism by cooling to below the Curie temp. USE/ADVANTAGE - To convert heat energy into mechanical energy.
Patent DE-4304187-A1 (DE)
Title: Method for speeding up access contention for stations connected to a bus system in communications switching systems
Inventor: SCHMIDT WERNER
IPC: H04L12/413
Filed: 1993-02-12
Abstract: To deal with access contention for stations connected to a bus system in communications switching systems, a method is intended to be indicated with which access contention can be completed in the shortest possible time. It is also intended to be possible to select the number of lines and the number of access stages as required without the need to modify the arrangement. A coded contention number is in each case switched fully or partially in parallel onto a plurality of access lines. In each station, a comparator is provided which is connected to the access lines and which establishes whether a transmitted contention number has a lower value than a coding present on the access lines. If so, a station is immediately excluded from further access contention. The coding of a contention number is selected in such a way that the sum formed on the access lines immediately corresponds to the transmitted contention number with the highest value. In the case of a small number of stations, the access contention can be restricted to a single access stage only and is thus completed in a very short time. Even in the case of a plurality of access stages, the time required for access contention is shorter than in known methods.
