Abstract: The invention pertains to a method for producing ethylene homopolymerizates and ethylene copolymerizates exhibiting a lower mass density of up to 0.930 g/cm3 and a melt index ranging from 0.15 to 25 g/10 min (2.16 kg; 463 K).  Said polymerizates exhibit an improved processing stability and improved availability in the installation at pressures greater than 1000 bar and at temperatures of up to 603 K.  The polymerizates are produced in tubular reactors in the presence of radical-forming initiators, oxygen thereunder and chain transfer agents, of which at least one comprises an aldehydic structure. According to the inventive method, chemokinetic characteristics of the reactive feed materials (thermal half-life periods, concentrations, dosing quantities) are coupled with fluidically relevant characteristics of the tubular reactor (flow rate) while taking the target product quality (melt index, flow figure) into consideration. This coupling is carried out such that the interfering secondary reactions, especially polar-inductive substitution effects, which can lead to the formation and the enrichment of organic hydroperoxides are reduced to a minimum and, as a result, extraordinarily stable processing conditions can be obtained.

Title: Apparatus for evaluation of skin impedance variations
Inventor: SZOPINKSI JAN ZBIGNIEW
IPC: A61B/
Filed: 1999-07-06
Granted: 2004-09-07
Abstract: The invention provides an apparatus and method for automatic evaluation of skin resistance or impedance variations in order to diagnose the state of health of at least a portion of a human or animal body , The difference between an AC impedance measured at a specific frequency and at a specific skin area with a calibration electrode and a reference electrode and the impedance measured at a similar frequency and in the same area with a measurement electrode and a reference electrode, is used to determine the state of health of the internal organ corresponding to the examined skin area. Alternatively, the skin between the electrodes is exposed to a DC potential of a magnitude selected to give a break-through effect. The resistance of the skin is measured between a measurement electrode polarised negatively with respect to a reference electrode, and the DC resistance of t he same skin area is again measured but with the measurement electrode polarised positively with respect to the reference electrode. The ratio of these two values is used to determine the state of health of the internal organ corresponding with the examined skin area.

Abstract: A spine-stabilization implant (30) comprises a one-piece bullet shaped shell with bone tapping screw threads (32) on its outside surface. the screw threads are longitudinally interrupted by several end to end flutes (34) distributed in parallel around the circumference. Bone growth access windows are (36) provided at several locations through the flutes. Such construction gives the spine stabilization implant a hexagonal cross section with a hollow central core (38). A drive tool can be slipped into the back end. After spreading two adjacent vertebrae as much as the interconnecting tissues will allow, a bore is made by a surgeon during an operation into the intervertebral space of a patient's spine, e.g., deep into, the disc. The drive tool is then used to push the spine stabilization implant down the bore, and into the intervertebral space. The tool is then twisted such that the bone tapping screw threads cut into, and lock onto the opposite surfaces of the adjacent vertebrae. The tool is then withdrawn. Morsel bone is packed into the spine stabilization implant to promote new bone growth that will fuse together the opposite surfaces of the adjacent vertebrae.
