Title: Monitoring equipment for a drive control for lifts
Inventor: GERSTENKORN BERNHARD
IPC: G05B9/02
Filed: 1998-09-22
Granted: 2008-06-17
Abstract: This monitoring equipment (1) for a drive control for lifts consists substantially of two modules, a safety circuit sensor system (2) and a motor-switching and/or brake- switching circuit (3), wherein the monitoring of a safety circuit (4) and the consequential actions resulting therefrom takes place exclusively by means of electronic components whilst avoiding electrically conductive separating locations. By the use of electronic components, electromechanical switching elements, which have electrically conductive separating locations, can be dispensed with. In addition, an appreciable reduction in the noise level is achieved, since switching noises no longer arise. This has an advantageous effect particularly in the case of lift installations without machine room. Furthermore, the manufacturing costs can be significantly reduced and a high security and reliability of the monitoring equipment (1) can be ensured by the use of usual electronic components.

Abstract: The present invention is a thermally reversible gel or geling copolymer that is a linear random copolymer of a [meth-]acrylamide derivative and a hydrophilic comonomer, wherein the linear random copolymer is in the form of a plurality of linear chains having a plurality of molecular weights greater than or equal to a minimum geling molecular weight cutoff. Addition of a biodegradable backbone and/or a therapeutic agent imparts further utility. The method of the present invention for making a thermally reversible geling copolymer has the steps of: (a) mixing a [meth-]acrylamide derivative with a hydrophilic comonomer in a solvent with an initiator forming a reaction mixture; (b) copolymerizing the reaction mixture and forming a first linear random copolymer having a plurality of linear chains having a plurality of molecular weights; and (c) purifying the synthesized first random copolymer and obtaining a second linear random copolymer having a plurality of molecular weights greater than or equal to a minimum geling molecular weight cutoff. The gel is enhanced by either combining it with a biodegradable backbone and/or a therapeutic agent in a geling solution made by mixing the copolymer with an aqueuos solvent.  Advantages of the present invention include (1) the thermally reversible gel of the present invention exhibits a thermodynamic stability, and when geled, will not reverse to the liquid state upon dilution but may reverse to the liquid state only in response to a temperature change and (2) the gelation occurs without substantial syneresis. Moreover, the thermally reversible gel of the present invention has lower initial viscosity more suitable for tissue perfusion.

Granted: 2009-12-22
Abstract: Faults on power lines are detected by measuring the voltage and current at one end of a power line and uses these measurements, together with values of series and shunt parameters of the line, to calculate values of voltage and current at an intermediate point on the line - the so-called "reach point". At least the calculated voltage is used to determine whether a fault lies within a particular zone on the line. The calculation utilizes a value of a derivative of said measured current with respect to time and is able to take into account the sectioning of a line into discrete lengths corresponding to, for example, overhead and cable sections. To increase accuracy, the line or each discrete section of the line is conceptually divided into subsections each having their own parameter values. In a second aspect of the invention, detection of whether a fault lies within a particular zone involves the measurement of first-end voltage and current both before and after the fault, the calculation of the complex impedance between an intermediate point of the line and a reference point, normally earth, using these measured values and values relating to line parameters and to a source impedance of the second end of the line, and the determination of the sign of the complex impedance.
