Title: Aerodynamic drag reduction fairing
Inventor: FLEMMING GEORGE M
IPC: B62D35/00
Filed: 1993-07-06
Abstract: AN AERODYNAMIC DRAG REDUCTION FAIRING          ABSTRACT OF THE DISCLOSURE            An aerodynamic drag reduction fairing is mounted on a substantially vertical rear surface of a vehicle. The fairing body comprises a generally inverted U-shaped member with a transverse top portion and a pair of depending legs upon the top and sides respectively of the rear surface. The body has a surface which is contiguous with the outside surface of the vehicle at the top and sides and then converges in a curve shape inwardly and rearwardly to a trailing edge spaced rearwardly of the rear surface. The spacing of the trailing edge from the rear surface is greater at the top than at the bottom of the sides legs. From the trailing edge the body extends back-to the rear surface to form a hollow interior inside the top portion and the legs. This can be inflated so that the body can be formed from a flexible fabric.

Title: Process for Finding the Overall Monitoring Threshold During a Bit-Rate-Reducing Source Coding
Inventor: SEDLMEYER ROBERT
IPC: H04B1/66
Filed: 1992-07-21
Abstract: In order to find the overall monitoring threshold during a bit-rate-reducing source coding of digitized audio signals, a requantization and coding regulation for the time or spectral scanning values of the audio signal is found from the masking effect of all relevant maskers and noise maskers and from the steady audio threshold.  To this end the masking sides of the selected maskers are segmented and approximated in the individual segments by low-order polynomials, whereby the coefficients of the low-order polynomials are found.  The intensities of the maskers converted into a logarithmic level are used to find the coefficients of the low-order polynomials. The overall monitoring threshold is found at individual or eventually selected support points in steps, masker by masker, from the polynomials describing the masking sides of the eventually selected maskers.

Patent CA-2114010-A1 (CA)
Inventor: SIRHAN MOTASIUM M
IPC: A61M25/00
Filed: 1992-07-23
Abstract: 2114010 9301856 PCTABS00019 A balloon dilatation catheter which has a coiled supporting element (17) disposed within a guidewire receiving inner lumen (11) extending within the interior of the balloon (16). Substantially, lower profiles can be obtained with catheters of this type, particularly with perfusion-type dilatation catheters with little chance that the inner member will collapse when the balloon is inflated to high pressures. Additionally, the coiled supporting element (17) provides much smoother transitions at the ends of the balloon and thereby improves the trackability of the catheter over the guidewire.

Title: Process for preparing a poly-1-olefin
Inventor: BREUERS WERNER
IPC: C08F10/00
Filed: 1994-03-01
Abstract: Abstract Process for preparing a poly-1-olefin By means of a highly active spherical Ziegler catalyst based on a dialkylmagnesium, spherical polymers can be obtained  in  the  polymerization  of  alpha-olefins.  A further advantage of the catalyst of the invention lies in the high catalyst activity, so that only vary small amounts of the catalyst are required for the polymeriza-tion. The residual titanium and/or zirconium content in the polymers prepared according to the invention is less than 10 ppm. Owing to its good responsiveness to hydro-gen,  the catalyst is particularly suited to two-stage processes for preparing polymers having a broad bimodal molecular weight distribution. The replacement of sulfur-containing electron donors such as diethyl sulfite by alcohols such as ethanol leads to less odor problems and broadened opportunities for use of the polymer.  Owing to the spherical shape of the particles and the associated very good flow behavior of the polymers and copolymers, considerable simplification and advantages in handling, drying and processing are achieved.

Patent CA-2120823-A1 (CA)
Title: Metabolic analyzer
Inventor: HOWARD CHARLES P
IPC: A61B5/0205
Filed: 1994-04-07
Abstract: A metabolic rate analyzer is provided comprising a CO2 detector, an O2 detector, a flow resistance, a differential pressure transducer, a solenoid-actuated metering valve for producing a volumetrically-proportional sample of respired gas, a vacuum regulator for receiving the sample, a pump for drawing the sample from the vacuum regulator and a processor for periodically sampling the differential pressure signal to provide a flow signal, to modulate power applied to the solenoid-actuated flow proportioning valve and to provide a measure of the total volume of respired gas. The processor correlates the total volume of respired gas, O2 content and CO2 content to provide a measure of metabolic rate. Flow is recycled between the pump and the regulator valve to provide a source of mixed respired gas for analysis and digital integration of the flow signal provides a measure of the total volume of respired gas. A pulse generator driven by the microprocessor varies the frequency of pulses applied to the metering valve and the pulse width to provide volumetrically-proportional sampling and to control the effective sample volume of the analyzer, respectively. The processor determines the slope of the flow signal and increases the periodic sample rate of the pressure signal when slope is increasing and decreases the periodic sample rate when slope is decreasing to provide derivative augmentation of the sample period.

Title: Strain relief for an electrical appliance
Inventor: MARCHETTI MICHAEL J
IPC: H01R13/585
Filed: 1994-06-21
Abstract: STRAIN RELIEF FOR AN ELECTRICAL APPLIANCE        ABSTRACT OF THE DISCLOSURE    A strain relief for an electrical supply cord of an electrical appliance includes a first member pivotally connected to the housing of the appliance.  The member includes a generally planar surface.  A second member is connected to the housing and has a generally planar surface facing and parallel to the planar surface of the first member.  The planar surfaces are spaced from each other to define an electrical supply cord receiving slot.  An electrical supply cord is movably disposed in the slot in a direction parallel to the longitudinal axis of the cord.          Movement of the cord in either longitudinal direction causes the first member to rotate relative to the second member so that as the planar surface of the first member moves relative to the planar surface of the second member the width of the cord receiving slot is reduced.
