Abstract: NON-A, NON-B HEPATITIS ASSAY AND VACCINE                 ABSTRACT OF THE INVENTION    A newly discovered particle in the urine and serum of non-A, non-B hepatitis patients has been associated with non-A, non-B hepatitis.  The particle resembles a togavirus and is 50-60 nm in diameter with a discrete core of about 40 nm in diameter.  The virus loses its infectivity for tissue culture upon heating at 25° C in aqueous suspension or by exposure to ether.  The particle may be cultured in vitro or recovered from body fluids or tissues to make immunoassays and vaccines.  The immunoassays may be em-ployed to detect the particle antigens or antibodies thereto in test samples.

Abstract: Abstract of the Disclosure A method and apparatus  for determining  a representative average weight reading is disclosed, based on a series of weight readings from a scale subject  to  vibrations.   Signals  are  generated  at regular  intervals,  representative  of  the  weight readings from said scale.  Each new weight signal is compared with the previous weight signal, and one of two  alternative  labels  is  assigned  to  each  new weight signal according to whether it is greater or less than the previous weight signal, and the oppo-site of the previous label is assigned if the signals are equal.  The weight signals occurring in a weight averaging interval, which extends from a label change in one direction to the next label change  in the same direction, are then averaged.

Granted: 1985-03-12
Abstract: Abstract of the Disclosure A fluid shear coupling apparatus is disclosed herein which includes a driving member received within a working chamber defined by a driven member.  The driven member is mounted with needle bearings to a shaft portion of the driving member to have the members rotatable about a common axis.  The driving and driven members include complementary shaped and positioned fluid shear and thrust surfaces defining fluid shear and thrust chambers, respectively, therebetween and cooperable with shear fluid within the chamber to transmit torque and axial thrust loads between the members.  The fluid shear surfaces are defined by interdigitated ridges and grooves.  A shear fluid reservoir is located in the central portion of the driven member and passageways lead from an annular groove and cylindrical cavity adjacent the driving member back to the reservoir.  A recycle passageway also leads from the annular groove and connects with the working chamber at a radially-inward location to provide recirculation of shear fluid through the working chamber.  Several projections and dams are received within the cylindrical cavity and annular groove to provide shear surfaces for transmitting torque between the driving and driven members, and also to facilitate the pumping of the shear fluid from the working chamber back to the reservoir or through the recycle flow path.  A weighted valve and associated temperature-responsive valve provide for modulated coupling between the driving and driven members.

Abstract: ABSTRACT     A microwave frequency divider operable in 2-16 GHZ range over octave bandwidths. A circuit resonant at a subharmonic frequency is formed by a pair of input microstrip transmission lines coupled to a pair of output microstrip transmission lines.  Each input line is terminated by a varactor diode.  The input signal is supplied to the resonant circuit by a pair of microstrip lines functioning as a two stage quarter wave transformer.  A pair of slots are formed in the ground plane underneath the resonant circuit. The electric field distortion thereby produced serves to bias the varactors into forward conduction for efficient subharmonic generation.     mb/

Abstract: APSTRACT OF THE DISCLOSURE A method of treating the unset surface of Portland cement concrete to form thereon a hardened surface, that is an integral coating, skin, treatment or mass of high early compressive strength, without sub-stantial shrinkage during setting while exhibiting re-duced wet and dry volume changes in the hardened state and possessing a high degree of impermeability to fluids, abrasion, erosion and chemical resistance and similar characteristics desired in a surface treatment having commercial usefulness in a construction industry. The hardened surface is obtained by dry shaking, that is, sprinkling a dry cementitious composition of alumina cement and gypsum on the unset Portland cement concrete. Additional components, such as viscosity controllers, surface active agents, retarders, accelerators, wet expansion inhibitors, gas generating or gas releasing agents, fly ash, plasticizers, pigments, water retentiv-ity aids, fillers, and aggregates may be utilized to adjust the properties of the composition and impart selective improvement of specific properties.

Abstract: ABSTRACT OF THE DISCLOSURE           This specification discloses a method for generating an engine energy output signal for use by an adaptive strategy in controlling the per-formance of a spark ignited automobile combustion engine.  An estimated future energy output combines the weighted sum of a short term energy output average, a medium term energy output average and a long term energy output average.  The adaptive strategy adjusts spark timing and distance  of EGR as a function of engine energy usage per distance traveled while maintaining feedgas emissions at a constant level over a wide variety of driving patterns including urban, suburban and highway.  This adaptive strategy has advantageous fuel consumption charac-teristics which are greatest at the most constrained feedgas levels.  Drivability can be enhanced because of the greater calibration flexibility inherent to the adaptive technique.

Abstract: ABSTRACT OF THE DISCLOSURE    Adsorptive, protein-binding aluminum oxyhydroxides are prepared by mixing carbonate-free, highly hydrated, aluminum oxyhydroxides containing aqueous suspensions with water soluble additives that furnish coordinating moieties with the aluminum compound and drying the resultant mixture.  The protein-binding aluminum oxyhydroxides can be made resuspendable by acidifying to a pH valve of between about 4 and about 6.5.  Such acidification can occur either before or after drying.  The novel adsorptive protein-binding agents have particular utility in the manufacture of topical skin compositions.

Abstract: Abstract An extension cord of flat cable, particularly for undercarpet use, comprising a strip of insulated conductors located in a stiffly flexible sleeve-form shield strip mounted at opposite ends in rigid outlet supporting housings with the conductors terminated to leads of the outlets. At one end of the cable, both the shield strip and the conductor strip are fixed to the housing preventing relative longitudinal movement, whilst, at the other end, only one of the strips is fixed to the housing, the other strip being free to move relatively longitudinally during a change in the extension cord from reeled to flat condition, thereby avoiding straining the terminations or buckling the cable. In one example, the shield strip is fixed to the housing and the individual conductors of the conductor strip are connected to leads of the associated outlet by flexible metal bands bowed perpendicularly to the plane of the strip.

Granted: 1986-06-24
Abstract: ABSTRACT An optical disk system having direct read after write capabilities in which the write beam and the read beam are generated by a pair of integrated injection diode lasers. The integration can be achieved by mounting two separate injection diode lasers side by side in a common package or providing two side by side injection diode lasers formed on a common semiconductor substrate. The two lasers would be located in the same focal plane relative to a recording material, with one of the lasers pulse modulated to provide a data modulated write beam and the other laser driven in the continuous wave (CW) regime to provide a read beam of constant intensity. The plane containing the focused beams would be oriented relative to the recording material so that the focused beams impinge upon adjacent portions of one data track of the recording material. Since the pair of lasers are closely spaced (1-1000 microns) a common optical path or train is used for both the write beam and the read beam.
