Abstract: A method  for  the  formation  of  double  stranded nucleic  acid molecules  from  separate  single  stranded nucleic  acid molecules  in  a  single phase  reaction solution is disclosed wherein the rate of reaction is greatly increased over the rate of reaction at standard reference conditions.   The greatly accelerated reaction rate is accomplished through the use of known concen-trations of nucleic acid precipitating agents which are added to the reaction solution.  Nucleic acid denaturing agents may also be added.   The solution so formed is incubated and then assayed for the presence of double stranded nucleic acid molecules.

Title: Transfer printing method
Inventor: HANSTEIN FRIEDRICH
IPC: B41M5/035
Filed: 1986-10-08
Granted: 1991-03-19
Abstract: ABSTRACT OF THE DISCLOSURE    Solid plastic objects, or objects having a plastic or lacquer surface layer are imprinted in a transfer printing process by placing a flat dye vehicle against the surface of the solid object to be printed and heating the dye vehicle to the sublimation temperature of the dye.  During the dye transfer, a layer of a material which does not adhere or adheres only weakly to the solid object and is to a large extent permeable to the transfer of the dye is placed between the surface to be printed and the dye vehicle, thus avoiding dye vehicle impressions on the surface.          Preferably, a plastic plate coated with a polyolefin film is printed upon, whereby the film is left on the surface as a protective coating after the printing.

Granted: 1991-12-31
Abstract: ABSTRACT OF THE DISCLOSURE         In order to eliminate background noise infiltrating into an input audio signal, a noise-canceling apparatus includes: first and second acoustic pickups for primarily picking up the audio signal and noise, respectively; a filter receiving the output of the second acoustic pickup; a subtracter for subtracting the output of the filter, when the audio signal is silent, from the output of the first acoustic pickup; and a coefficient determination for determining coefficients of the filter so as to make the filter generate a noise signal corresponding to a signal generated by passing the noise through a transmission path having a transmission frequency characteristic from the noise source to the first acoustic pickup.  The coefficients of the filter are determined on the basis of mutual-correlation coefficients between the outputs of the first and second pickups and self-correlation coefficients of the output of the second pickup, thereby improving the processing efficiency.

Title: Valve for use in well bores
Inventor: HASSANZADEH HEDAYAT H
IPC: E21B21/10
Filed: 1986-11-03
Granted: 1990-02-20
Abstract: ABSTRACT VALVE FOR USE IN WELL BORES A dual purpose valve for use in well bore casings has a body (12) supporting a valve seat (18), a movable valve element (24) axially movable to a guide (22) and having a closure means (28) adapted in one position to sealingly contact the seat (18) to act as a back flow preventer. The valve defines a passage for fluid flow of sufficient cross section that it can serve as an automatic fill valve for permitting well bore fluid to flow into a casing string. A releasable locking means (32) is inserted in or adapted for insertion in the valve body in a locking position, in which the locking means contacts the valve element (24) to prevent movement of the valve element towards the valve seat to convert the valve, on site, from a back flow preventer operation to an auto fill valve operation. The locking means formed so that, when released, it falls away from or retracts to release the valve element. Preferably it comprises a plurality of segments (34).

Abstract: LOW-STRESS SHIELDED EXHAUST PASSAGE ASSEMBLIES Abstract An exhaust manifold, cylinder head, or the like, is provided with one or more insulating shield members formed within associated housing members having ball or cylindrical end portions.  The end portions are seated on bearing rings preferably cast or inserted into the housing ends to provide for relative expansion of the internal shields with respect to the outer housing members, both linear and bending expansion motions being accommodated.  The resulting passage assemblies may be formed by casting the housing members around their respective shields.  Sand core material may be preapplied to create the desired insulating clearance between the associated members and, if desired, to secure the bearing rings in position.

The slider  member   (28)   slideably   disposed   in  a passageway (24) extending longitudinally through the support  member  (16).    The  slider  member  (28) includes a plurality of locking teeth (64) spaced an equal distance apart longitudinally along the slider member  (28).   The support member  (16)  includes a guideway  (38) which supports a  latch member  (42) with a  single  tooth  (66)  for engagement with the locking teeth (64) of the slider member (28).   The assembly is characterized by a cap member (48) which connects the latch member (42) to the biasing means (56) and pivots about one end (50)  for moving the latch member  into and out of engagement with the slider member  (28).   The cap member  (48)  allows transmission of a resultant force from the biasing means (56) only in a direction which is aligned with the transverse movement of the latch member (42) to prevent torsional forces from being transmitted to the latch member (42) from the biasing means (56).

Granted: 1991-05-14
Abstract: ABSTRACT        A folding table construction embodying a planar top, foldable legs and a novel apron assembly connected to the under-side of the top.  The apron unit comprises elongated discrete, relatively short straight lengths of formed metal side and end strips, or stringers, which are securely interconnected together by spaced apart, one-piece, blow molded corner moldings adapted to be affixed to the underside of the table top.   Due to the novel design of the corner moldings and the stringers, the con-struction of the supporting apron requires no metal bending or welding.  Further, the corner moldings can be colored during the molding step and the stringers can be painted to match in small painting units prior to apron assembly.

Abstract: RADIOMETRIC IMAGER HAVING A FREQUENCY-DISPERSIVE               LINEAR ARRAY ANTENNA                 ABSTRACT OF THE DISCLOSURE A radiometric imager for providing a series of registered images of a scene, each image corresponding to the radiation pattern for a unique, narrow frequency band.  One embodiment includes a single frequency-dispersive linear antenna providing an output signal based on a series of conical fanbeams, with the antenna being controllably rocked about one axis and rotated about a perpendicular axis such that each fanbeam intersects each segment of the scene a plurality of times.  In alternative embodiments, the imager includes a second frequency-dispersive linear antenna arranged in parallel with the first antenna to produce a fanbeam interferometer.  Rocking movement of the two antennas coupled with either translation of the two antennas, rotation of the two antennas about an axis parallel with the antenna axes, or movement of the two antennas toward and away from each other, provides sufficient data to permit creation of the registered images.

Title: Antenna orientation adjusting device for earth station
Inventor: YOSHIHARA MASASHI
IPC: H01Q1/12
Filed: 1987-09-15
Granted: 1991-08-06
Abstract: ABSTRACT OF THE DISCLOSURE A device for adjusting the orientation of an antenna for an earth station. A received signal coming in through the antenna is delivered from an outdoor unit to a demodulator of an indoor unit to be demodulated thereby. In the indoor unit, a converter receives an automatic gain controlled voltage signal from the demodulator and converts it into a digital signal, and a controller converts the digital signal into a predetermined control signal to feed it to the outdoor unit over the cable. In the outdoor unit, a display responsive to the control signal indicates a particular level which corresponds to the automatic gain controlled voltage. A person, therefore, can adjust the antenna to an optimum orientation unassisted, i. e., while observing the display.
