Title: Normalisation of energy states of biological systems, organs or glands - using two-phase treatment with application of controlled dose of bio-effective radiation to negate measured deviation from normal activity
Inventor: CHERDRON EGON DR
IPC: A61N1/16
Filed: 1992-02-17
Abstract: The method involves measuring quantitative deviations of organic energy states from their normal healthy values, expressed in 'bio-energetic units', in the direction of either hyperactivity or hypoactivity in an error-free manner, by a 'Copen Radionic Analytical Computer MK 5' (RTM) or comparable appts., supported if necessary by measurement of reaction to circularly polarised microwaves of geophysical origin. In a second phase, the measured deviations are corrected by application of precisely defined, metered and time-limited doses of bio-energetic radiation directed at specific parts of the body. The treatment is repeated as often as necessary until zero deviation is measurable for at least 25 minutes afterwards.

IPC: D01H7/86
Filed: 1992-05-16
Abstract: A yarn folding and twisting spindle has a rotor with a hollow spindle, and a bottom plate passage in which are fitted yarn directing sections. The passage through the sections is parallel to the spindle axis, an eccentric. Pref. two or more yarns are fed from the package into the top of the hollow spindle, along the bottom plate passage and vertically into the pot, to the creel above. The folding and twisting to a cord is created by the spindle drive in one direction, while the pot is driven in the opposite direction. The yarn is angled by the sections from axial to radial, and reverse. The sections are made in two pieces. The top piece has an angular top face with an enlarged or conical bore, and a curved half section at the bottom, which aligns to the other half section of a curved bore, directed to the bottom passage. An identical two part section then reverses the direction of the yarn to the interior of the balloon restriction pot. The re-direction sections are made from sintered ceramic, to prevent nicking. ADVANTAGE - The re-direction of the yarn from the hollow spindle to the bottom plate passage, and then vertically to the pot, is through large dia. sections.

Abstract: A process is disclosed for producing a ski edge made of quenched and subsequently tempered steel having a head (2) that comprises the running surface and a flank (4) that projects into the body of the ski. The profiled edge (1) is at first rolled, then quenched and subsequently tempered over its whole cross-section.
