Title: Progressive scan television system with sum and difference components
Inventor: STROLLE CHRISTOPHER H
IPC: H04N9/80
Filed: 1987-01-16
Granted: 1992-07-28
Abstract: RCA 83, 054 ABSTRACT PROGRESSIVE SCAN TELEVISION SYSTEM WITH SUM AND            DIFFERENCE COMPONENTS A progressively scanned video signal is encoded into temporal sum (Y) and difference (M) components for transmission.  The sum signal is temporally filtered, decimated and time expanded to be compatible with interlaced receivers.  The difference signal, also temporally filtered, decimated and time expanded, is conveyed via single or separate channels with the sum signal to a progressive scan receiver (14) for reconstitution of the original progressive scan signal. Modified quadrature amplitude modulation is used to convey the sum and difference signals in a common channel.

Title: Non-contact web turning and drying device
Inventor: HAGEN KENNETH G
IPC: D21F5/18
Filed: 1987-02-27
Granted: 1992-04-28
Abstract: ABSTRACT         Disclosed is an apparatus for transporting a web about a nonlinear path without allowing the apparatus to contact the web.  The apparatus includes a series of positive pressure nozzles which emit A primary jet flow of fluid in a single direction, and a secondary jet flow of fluid in a direction perpendicular to the primary flow.  The two flows merge and transport the web on a cushion of air along the nonlinear path.  The magnitude of the cushioned pad is controlled by a series of slide dampers which are positioned between adjacent nozzles, and the opening of these slide dampers controls the amount of exhaust from the merged flow so as to control the cushioned path.  The last nozzle in the series will direct its primary flow in a direction opposite to that of the other nozzles in the series in order to maintain the overall pressure pad under the web.  In an alternate embodiment, a second set of nozzles which provide a negative pressure are arranged around the convex side of the web to provide additional stability and to enable the drying of the web on both sides of the web.

Title: Digital signal demodulation system
Inventor: OHTSUKA HIROYUKI
IPC: H04B7/00
Filed: 1987-05-19
Granted: 1991-03-26
Abstract: ABSTRACT     In a digital signal demodulation system in a dual polarization radio system, having a first demodulator and a first A/D converter for a main signal, a second demodulator and a second A/D converter for an interference signal (cross polarization signal), a transversal filter for providing a compensation signal for cancelling an interference component in the main signal depending upon the demodulated interference component.  The second A/D converter for providing the interference component in digital form is operated with a clock signal regenerated in the main signal branch so that the system operates correctly even when the main signal and cross polarization signal are in an asynchronous condition.  The A/D converter is provided with an attenuator for compressing the amplitude of an input signal to avoid saturation of the circuit in case of fading and/or distortion, and a ROM table for correcting digitalized output after equalization and/or cancellation.  Tap coefficients of the transversal filter are obtained by a control through a ZF (zero-forcing) method when inter-symbol interference is small, and a MLE (maximum level error) method when inter-symbol interference is large.  Further, an integration constant for the tap coefficients is adaptive depending upon inter-symbol interference.

Title: Stator assembly for dynamoelectric machine

IPC: H02K19/06
Filed: 1988-07-04
Granted: 1990-12-18
Abstract: Abstract of the Disclosure An adjustable speed inductor type rotating dynamoelectric machine, capable of high speed operation, employs a stator assembly incorporating a spool-like support structure.  A central, generally cylindrical portion of the support structure supports field windings while radially oriented end portions of the spool-like structure mount and accurately position a circumferentially distributed plurality of C-shaped armature core elements.  Radially directed, angularly spaced grooves in the outer surfaces of the end portions receive legs of the C-shaped armature elements and serve to precisely position these elements in three orthogonal directions.  The central portion of the armature-field winding support structure may be made of electrically conductive material to provide a flux shield and dissipate heat.  For additional ventilation, cooling ports may be provided in the central portion of the spool-like support which cooperate with extended recesses in a coaxial rotor.  The rotating rotor centrifugally propels cooling fluid through said ports into the spaces occupied by the field windings and armature windings.

Abstract: Polyanhydrides with uniform distribution of alkyl and aromatic residues are prepared by melt polycondensation or solution polymerization of p-carboxyphenoxyalkanoic acids or p-carboxypheny-lalkanoic acids. These polymers are soluble in common organic solvents and have low metling points, generally in the range of 40-100°C. The polyanhydrides are especially well suited for forming bioerodible matrices in controlled bioactive compound delivery devices. A polymeric matrix formed according to the method described here degrades uniformly during drug release, preventing the wholescale channeling of the bio-active compound into the environment, and eliminating the problem of the presence of the polymer matrix at the site long after drug release. The polymer displays zero-order kinetic degradation profiles over various periods of time (days to months), at a rate useful for controlled drug delivery. Furthermore, a desired degradation rate may be obtained by choosing the appropriate length of the aliphatic moiety.
