Abstract: A method for enabling an increase in the vertical definition of a transmitted television signal while preserving its bandwidth including the steps of decimating alternate lines of the television signal and reinterpolating untransmitted alternate lines upon reception. The decimation is accomplished by diagonally filtering the television signal in two dimensions to form a figure of five sample structure. Every other line is then added to the line adja-cent to it so that half the lines are available for transmission, each line comprising folded-in high frequency information about missing line samples. Prior to transmission, bandwidth is conserved by fil-tering the signal to be transmitted at a skew-symmetric low pass filter. Apparatus for encoding and decoding the television signal each includes a two dimensional diagonal filter and line switching and control circuitry. The storage of a full field of sample data is not required for processing in accordance with the present method. Consequently the present apparatus comprises only line store means associated with the line switching and control circuitry of encoding apparatus.

Abstract: LIQUID ISOCYANURATE-MODIFIED POLYMETHYLENE BIS(PHENYLISOCYANATE) COMP0SITIONS CONTAINING A HIGH TWO-RING METHYLENE BIS(PHENYLISOCYANATE) CONTENT                    Abstract of the Disclosure A method for producing liquid isocyanurate modified Polymeric MDI composition containing a high two-ring MDI content, and foams made therefrom is described.  The method comprises trimerizing a polymeric MDI in the presence of catalytically effective amount of a trimerization catalyst to form an isocyanurate containing polyisocyanate having a viscosity of about 100,000 mPas.  The trimerization catalyst is thereafter deactivated and the isocyanurate-modified polyisocy-anate is blended with a methylene bis(phenylisocyanate (MDI) to form a final product having a two-ring content of about 60 percent of the total ring content and a viscosity comparable to polymeric MDI.  Foams produced using this liquid isocyanurate modified polymeric MDI are of a substantially lighter color than those produced from standard polymeric MDI.

Abstract: Abstract Devices and analytical techniques are disclosed for measuring the spatial profile of permittivity of a material by multiple wavenumber interrogations.  Electrode structures are disclosed which define a number of different fundamental wavelengths (or wavenumbers).  Spatially periodic interrogation signals (of temporary frequency ".omega.") from the electrode structures are attenuated to varying degrees by the material undergoing analysis, depending upon the wavenumber ("k"), thereby permitting the derivation of a composite dielectric profile.

Abstract: IMPROVED THRUST VECTOR CONTROL SYSTEM       FOR AEROSPACE VEHICLES               ABSTRACT OF THE DISCLOSURE        An improved thrust vector control system for steering and controlling an aerospace vehicle pro-pelled by a reaction type motor. The improved thrust vector control system simultaneously rotates and laterally translates the reaction motor with respect to the longitudinal axis of the vehicle. This complex motion of the reaction motor generates sufficiently large control moments that allows the reaction motor to be moved very close to the center of gravity of the vehicle. As a result, the vehicle can be short-ened and the structure that is typically required to position the reaction motor at a swivel point farther aft eliminated.

Abstract: Alcoholism and alcoholism susceptibility in a patient are determined by measuring a cellular indicator which is characteristic of intracellular cAMP concentration.  In particular, intracellular cAMP concentration may be measured in freshly isolated lymphocytes, where a reduction in the concentration compared to the expected normal value is diagnostic of alcoholism.  Alternatively, stimulated intracellular cAMP concentration may be measured in cultured cells not exposed to ethanol where an increase in the concentration compared to the expected normal value is indicative of a predisposition toward alcoholism. Also, decreased cAMP levels may be measured in cultured cells from alcoholics exposed to chronic ethanol where no decrease in the concentration of cAMP occurs when normal cultured cells are exposed to chronic ethanol.

Title: Method and circuitry for carrier recovery for time division multiple access radio systems
Inventor: CHUANG JUSTIN C
IPC: H04L27/227
Filed: 1989-04-12
Granted: 1993-01-05
Abstract: ABSTRACT OF THE DISCLOSURE Coherent phase recovery in a time division multiple access (TDMA) system can be attained in a novel manner. After symbol-timing and frequency-offset are estimated, the stored received phase at the desired sampling instant is gated from memory and fed to the input of the carrier phase recovery circuitry. During a first half portion of a burst, the first half portion of the burst is stored, while the loops acquire lock. The first half portion is then fed to one of the loops in a reverse order of its reception. Demodulation is initiated as a common state of both loops in a mid-portion of the signal burst. The previously stored first half portion is backwardly demodulated by one of the loops, while the other loop demodulates the second half portion of the burst. The whole burst is recovered by storing the demodulated first and second half portions in random access memory, and then reordering the stored demodulated burst by reading the memory backwards for the first portion.

Abstract: Title SELF-RETRACTING MODULAR COLLET ASSEMBLY                    Abstract of the Invention A collet assembly  includes  a self-retraction system for convenience of use and quick adjustment.   In a preferred form, the collet assembly is releasably retained against a top pressure ring normally biased apart from a base ring.  The pressure ring includes a plurality of elongated detents which extend axially from the pressure ring, each adapted for insertion into a detent-receiving socket of one die segment contained in an elastomeric cage.   Each detent is radially moveable with respect to the pressure ring,  such that as the die segments are contracted radially inwardly, the detents hold the segments to the pressure ring but permit movement of the segments radially with respect to the ring.  After each crimping operation, the detents, which are normally spring biased to their radially outermost position, will return the die segments to a fully opened position.  In addition, the pressure ring is retracted upwardly away from the base ring by means of an axial spring biasing system to provide clearance for  removing  the  finished  crimped  product  from  the  collet assembly.
