Title: Method for the treatment of cerebral ischaemia and use of erythropoietin or erythropoietin derivatives for the treatment of cerebral ischaemia
Inventor: EHRENREICH HANNELORE
IPC: A61K38/18
Filed: 1999-12-13
Granted: 2004-11-11
Abstract: The present invention relates to a method for the treatment of cerebral ischaemia and a drug for the treatment of cerebral ischaemia in particular in humans, as occurs for example in the case of stroke patients. It was found surprisingly that peripheral administering of erythropoietin to the cerebral tissue affected by the ischaemia has a distinctly protective effect. Erythropoietin has the effect thereby that the region of the cerebral tissue which is damaged permanently, in particular in the penumbra, is dramatically reduced relative to conventional measures in the case of cerebral ischaemia without erythropoietin administration.

Granted: 1993-10-05
Abstract: DATA COMMUNICATIONS WITH ALTERNATION               OF SIGNALING CONSTELLATIONS          Abstract Primary and secondary data are communicated from a transmitter to a receiver in a communication system. The value of an individual primary data word is communicated by transmitting an individual one of first plurality of channel symbols associated with that value while the value of a combined data word comprising an individual primary data word and an individual secondary data word is communicated by transmitting an individual one of second plurality of channel symbols associated with that value. In the receiver, both the primary and secondary data word values are recovered from the channel symbols thus transmitted. The approach of alternating two sets of channel symbols for transmission depending on the data word size can further apply to data communications at various fallback speeds.

Title: Hypsometer having controlled heating, particularly for use in metrological radio-sondes
Inventor: RUPPERT PAUL W
IPC: G01L11/00
Filed: 1990-06-05
Granted: 1996-10-29
Abstract: The hypsometer comprises an open boiling vessel consisting of a vessel flask containing the measuring fluid and of a ves-sel neck attached to said vessel. An electrical heating re-sistor plunges into said measuring fluid. A temperature sensor measures the boiling temperature of said measuring fluid. The hypsometer comprises an adaptive control system for stabilizing the position of condensation zone in the vessel neck which ad-justs the heating capacity to a command value corresponding to the specific boiling temperature involved. In the simplest case, such control is realized by using, as heating resistor, a thermistor having a negative temperature coefficient. In this way, the heating capacity is adjusted, over the whole pressure range, to the specific needs. Thus, on the average, less heat-ing capacity is needed, resulting in a considerable reduction of the battery weight.

Abstract: Cylinders, whose front ends are opened and inner mid section has a retaining section, are fitted in a multiple holes bored on an outer circumferential face of a tire.  In each cylinder, a stud is inserted through a through-hole of the retaining section, the stud has an enlarged section, whose maximum diameter section contacts the inner face of the cylin-der, at the rear end section and an enlarged neck section at the front end.  The stud is biased toward the front end of the cylinder by a spring, which is provided between a lid closing the rear end of the cylinder and the enlarged section.  On a icy or snowy road, when the stud inclines by tire slip, the enlarged neck section at the front end of the stud catches the opening edge so as to keep projecting status, and the enlarged section bites icy or snowy road to prevent from slipping. While, on a dyr road the stud is pushed in the cylinder against the elasticity of the spring by weight of a car.

The latching tabs are resiliently coupled to the first tubular member for providing a snap fit along the plane of rotation.      In the first embodiment, the latching tabs of the first tubular member engage an inwardly extending flange on the second tubular member via a snap fit. Abutment members are provided on the inwardly extending flange for engaging the gaps between the latching tabs to selectively retain the first and second tubular members in a straight, or angled position. In the second embodiment, the first tubular member includes an annular wall having a plurality of latching tabs that engage an outwardly extending flange of the second tubular member via a snap pit. An abutment member on the first tubular member engages notches formed on the peripheral surface of the outwardly extending flange for selectively retaining the first and second tubular members in a straight or angled position. The fitting also includes a ferrule and nut for receiving and coupling an electrical conduit to the second tubular member. The nut has a tapered internal wall that compresses resilient tines of the ferrule about an electrical conduit, when the nut is tightened onto the second tubular member.
