Title: A method of welding together articles made of plastic material
Inventor: HAUG PETER
IPC: B29C65/20
Filed: 1998-07-14
Abstract: The invention provides a method of welding together articles made of a thermoplastic plastic material by means of a butt welding process, whereby the two articles to be welded together are held in place in coaxial relationship by means of clamping devices. Then, the two articles are heated up by means of a heating device that can be placed between the two articles to create a molten up welding zone in the region of each of the free ends of the two articles. As soon as the welding zone has reached the proper temperature, the two articles to be welded together are pressed together to create a bulge. Finally, the temperature of that bulge is continuously monitored and the temperature of the material in the interior of the afore mentioned welding zone is calculated according to the formula T M(t) = 0~ t(T BT,t)dt until such a temperature is reached at which the articles can be removed from the clamping devices.

Title: Methods of modulating radical formation by mutant cuznsod enzymes
Inventor: GOTO JOY J
IPC: A61K31/4015
Filed: 1997-01-24
Abstract: Familial amyotrophic lateral sclerosis (FALS)-associated mutant CuZnSODs, A4V and G93A, have been discovered to catalyze the generation of hydroxyl radical from hydrogen peroxide at higher rates than that of wild type CuZnSOD. The copper chelator diethyldithiocarbamate (DDC) has been found to inhibit both radical generation and SOD activity of mutant CuZnSODs A4V and G93A at DDC concentrations significantly lower than those required to inhibit wild type CuZnSOD enzyme. In a neural cell culture model of FALS, DDC reverses the effect of four FALS-associated mutants, but does not alter the survival of cells expressing only wild type CuZnSOD. Thus, radical formation may be modulated and ALS treated in subjects with a mutant CuZnSOD enzyme by the administration of copper chelating agents. Treatment can also be affected by the administration of radical scavenging agents, or the administration of expression inhibitors specific for the mutant genes.

Abstract: A surgical instrument assembly for excising a targeted tissue mass to be biopsied from adjacent bodily tissue of a surgical patient is disclosed.  The assembly has a tissue biopsy device and an expandable sleeve for receiving the tissue biopsy device. The biopsy device has a penetrating member affixed to a distal end of an elongated tube to facilitate insertion of the tube adjacent the targeted tissue mass. It also has a tissue receiving chamber at the distal end of the tube for receiving the mass and a tissue cutter movable relative to the penetrating member from first to second positions for excising the targeted tissue mass. The expandable sleeve provides an access portal to the targeted tissue mass. It is expandable from a first original diameter to a second expanded diameter in response to insertion of the tissue biopsy device where at least a portion of the device has a device diameter corresponding to the second expanded diameter. When the tissue biopsy device is inserted through the sleeve, and the sleeve expands, the surrounding tissue is dilated. The dilation of tissue is less traumatic to the patient than incisional length which matches the diameter of the penetrating member of the biopsy device.

Abstract: The invention relates to a method of and a device for the manufacture of dimensionally stable, liquid-impermeable, flexible, elastic pressbands, particularly for use with broadnip shoepresses of paper making machines.  The method comprising pouring a flowable mixture of a prepolymer onto a substrate moved by a distance maintaining device over a cylindrical mandrel and maintained during this movement in an adjustable distance from the surface of said mandrel, and being coated during this movement by a coating device with a flowable prepolymer, wherein during this coating of the substrate threads or wires are laid down onto the substrate in the direction of rotation of the mandrel and are coated with the polymer substance.  In order to provide a method of the initially specified kind in such a way that the manufactured pressbands have the required high strength and tensile stability and that they are able to maintain both over long times of operation, the invention proposes that a net, texture, knitted fabric or a similar structure is used as substrate tensioned over the surface of the mandrel and consisting of non-woven threads located transverse to the longitudinal direction of the pressband and forming meshes the width thereof is chosen dependent especially on the viscosity of the prepolymer mass such that the meshes are completely impregnated by the prepolymer mass poured onto the meshes and that the threads of the net, texture, knitted fabric or similar structure are completely coated by the meshes forming on the side opposite to the surface of the mandrel a closed, smooth surface of prepolymer material, the thickness of which corresponds to the distance of the substrate from the surface of the mandrel, which polymer material can be separated from that mandrel surface.

Abstract: The present invention is a method for linearizing amplifiers by measuring the intermodulation products at the output of the linearized amplifier using minimum additional hardware without the performance problems associated with pilot tones. In one embodiment, the amplifiers are adaptively linearized using performance monitoring radios. Specifically, the performance monitoring radios are used to measure the signal levels of the intermodulation products in unused communication channels. Such measurements are then used to adaptively linearize the amplifiers and reduce the levels of intermodulation products.

Abstract: A yarn feeder device for feeding elastic (soft) yarns to a yarn consuming station whose yarn demand fluctuations over time has a control unit which ascertains the current yarn demand or to which the current yarn demand is reported. In accordance with this demand, a yarn feed wheel is driven at a rotary speed suitable for the yarn demand. The yarn travels via a tensioning device to the yarn feed wheel. The tensioning device is arranged such that the yarn is stretched in a defined way. As a result, a fixed association between a desired yarn feed quantity and the rotary speed of the yarn feed wheel is possible.
