Patent CA-2046371-A1 (CA)
Title: Polymeric/polyimide compositions having enhanced electrostatic dissipation
Inventor: MERTZEL ELAINE A
IPC: C08L101/00
Filed: 1991-07-05
Abstract: ABSTRACT   The subject invention relates to an electrostatic dissipative polymeric composition. It has been found that the incorporation of a polyimide into a basepolymer will enhance the electrostatic dissipative properties (ESD) of the composition comprising a base polymer and an ESD additive. This enhancement of the ESD properties is illustrated by the decrease in both the surface resistivity and volume resistivity. In compositions employing the same ESD additive this enhancement provided by the incorporation of the polyimide could allow a reduction of electrostatic dissipative additive required to achieve acceptable results. Further, the improved properties could allow the material tobe adopted for specific applications that cannot be normally achieved without the enhanced properties.

Title: Fully floating inlet flow guide for double-flow low pressure steam turbines
Inventor: GROENENDAAL JOHN C JR
IPC: F01D9/02
Filed: 1991-07-17
Abstract: A fully-floating inlet flow guide for a double-flow steam turbine includes a pair of partially overlapping, generally cylindrical sealing rings circumscribing a turbine rotor adjacent a steam inlet with each of the bands being coupled to a respective one of a pair of first stage nozzle rings positioned on opposite, sides of the inlet for directing steam into an axial flow path. The rings are provided with an annular seal at their overlapping portions such that axial expansion and contraction is accommodating without steam leakage through the seal. Radial expansion and contraction of the sealing rings is accommodated by attachment of each ring to a respective nozzle using a circumferential groove in a radially inner surface of each nozzle ring diaphragm and a tongue on each of the rings which fits into a respective groove. Each tongue has a plurality of circumferentially spaced slots and a block slidingly positioned in each of the slots. A pin extends through the blade diaphragm at each slot and extends through the corresponding block so that the blocks are fixed with respect to the diaphragm. The blocks prevent rotation of the bands about the turbine rotor while permitting radial displacement of the bands since the blocks are only slidingly held in the slots.

Filed: 1990-03-13
Abstract: Disclosed is a cardiac biopotential analysis system and method for detecting and quantifying in a noninvasive manner nonlinear dynamic patterns of depolarization and repolarization on a beat to beat basis in real time using bispectral analysis. A suitable body surface electrode acquires the signal from a region of interest. The signal is then amplified, digitized, and transmitted to a host microcomputer where an arrhythmia-free QRST complex is chosen interactively. Using standard cross-correlation methods a suitable number of complexes are extracted from the record. The extracted complexes are used to compute bispectral parameters using a frequency domain or a parametric based approach. A reference clinical database is used to identify frequency pairs most sensitive to particular interventions or diagnostic states of interest. The values at these frequency pairs are then extracted from the patient's bispectral arrays. The ensemble of values for the particular diagnostic determination under consideration is used to compute a single value index which serves as the diagnostic criterion by which the patient's state is judged. In this way the quantification of nonlinear dynamic properties of the frequency structure of the QRST yields information about the presence and extent of coronary artery disease (CAD), myocardial ischemia, cardiac electrical stability, risk of malignant ventricular arrhydthmia, site(s) of origin of malignant arrhythmias, extent of malignancy of arrhythmias, degree of antiarrhythmic drug efficacy, neural and humoral inputs to the heart, pump function/ejection fraction, and ongoing organ rejection in cardiac transplant patients.
