Title: A racket for ball games
Inventor: KEILHAU KARL FRIEDRICH
IPC: A63B49/08
Filed: 1984-11-28
Abstract: A racket for ball games and more specifically, a tennis racket, has a frame forming a racket head, a shank and a grip secured to the shank with a force fit so that the grip may be turned in relation to the racket head into different settings. The force fit connecting elements are simple to manufacture, yet permit an exact stepless setting and a satisfactory transmission of the forces produced while still avoiding a slip clutch effect. The grip and the racket shank are joined with each other by a surface area of substantial size which assures the required frictional engagement for the force fit in the angular direction while providing a form locking connection in the axial direction. The shank is part of an integral, one-piece handle bar which also has a cylindrical section and a conical section integrally interconnecting the shank to the cylindrical section.

Title: Food-grade oxygen scavenger for water containing products
Inventor: EDENS LUPPO
IPC: A23L2/42
Filed: 1988-08-25
Abstract: The oxidative deterioration of water-containing products for human consumption, e.g. beverages and oil and/or fat based products is minimised by introduction of immobilised yeast. Yeast is immobilised in and/or on a solid material which allows only very slow penetration by water. Thin layers material of such a yeast-bearing solid, e.g. paraffin, wax, can be applied to the lining of crown corks. The yeast will retain sufficient viability, even after pasteurization of the contents of a container closed with the crown cork. The yeast will minimise the oxygen concentration in the contents between the time of pasteurization and eventual consumption of the contents.

Title: Vernier control system for subsynchronous resonance mititgation
Inventor: BOWLER COLIN E J
IPC: G05F1/20
Filed: 1993-05-14
Abstract: A subsynchronous resonance mitigation system, including a method and apparatus, for damping undesirable subsynchronous resonance oscillations in a generator, which, if left unchecked, may damage the shafts of a turbine-generator set. A remote coupling apparatus, such as a thyristor controlled series capacitor (TCSC) system, a sourced inverter device, or a static phase shifter, is coupled to the generator by a transmission line. In response to a firing command, the coupling apparatus introduces subsynchronous resonance mitigating currents into the transmission line. Sensors monitor power line parameters and/or the generator speed, and in response thereto, a higher-level controller generates a voltage command. A vernier controller responds to the monitored power line parameters and the voltage command to provide the firing command to the coupling apparatus.
