Title: Wall feedthrough
Inventor: NOLF JEAN M E
IPC: F16L5/02
Filed: 1987-04-14
Granted: 1991-09-17
Abstract: ABSTRACT WALL FEEDTHROUGH      A duct seal for sealing a duct (4) to a substrate (20) such as a feedthrough comprises a sealing member (6), d biasing member (8), such as a wrapped spring sheet and an insert (12) positioned between the substrate (20) and the sealing member (6). The biasing member (8) can be operated, through the insert  (12) from the outside of the duct.   When the substrate is a feedthrough (20), for example, it is advantageous that the biasing member (8) is operated through the insert rather than through the feedthrough (20) itself, since it allows the feedthrough to be temporarily sealed against contaminants.

Title: System for sensing abnormal heart activity by means of heart rate acceleration and deceleration detection
Inventor: IMRAN MIR
IPC: A61B5/0245
Filed: 1987-05-13
Granted: 1992-06-23
Abstract: ABSTRACT OF THE DISCLOSURE            A heart rate acceleration/deceleration detecting systems particularly for use with an automatic defibrillator/cardioverter. The detection system detects a series of heart beats and determines, for a group of beats, such as on a beat-by-beat basis, whether the heart rate has accelerated above a first predetermined value. If such acceleration is determined, the system checks to see if the acceleration of the heart beats was followed by an immediate deceleration that exceeds a predetermined value. If a large acceleration followed by an absence of a large deceleration is detected, a signal is provided to an arrhythmia detecting logic circuit as an indication of an arrhythmia that may be appropriate for treatment by the defibrillator/cardioverter. The acceleration detection system is also capable of determining if a large deceleration preceded the detection of the large acceleration. If a large deceleration preceding a large acceleration had been detected, the system assumes that an AGC dropout in a rate detector circuit had occurred and will not provide an output signal to the arrhythmia detecting logic circuit. The system is also capable of detecting premature ventricular contractions by the existence of a large acceleration followed immediately by a large deceleration.

Title: Liquid mixing employing expanding, thinning liquid sheets
Inventor: DEMYANOVICH ROBERT J
IPC: B05B1/26
Filed: 1988-03-22
Granted: 1992-02-25
Abstract: LIQUID MIXING EMPLOYING EXPANDING, THINNING LIQUID SHEETS                          Abstract Two or more liquids are mixed continuously in very short times and in a highly uniform manner. Thin sheets of the liquids to be mixed are formed and contacted to produce a new mixed sheet. The newly formed mixed sheet is highly turbulent which substantially enhances mixing. Since the contacting of the liquids occurs on a scale of microns of thickness, mixing is not only rapid but complete and extremely uniform as well. Turbulence within the mixed sheet that further enhances mixing allows for mixing times as low as 0.1 millisecond, depending on flowrate and pressure drop, for low viscosity fluids.
