Abstract: METHOD OF GROWING OXIDE LAYER ON INDIUM GALLIUM ARSENIDE            Abstract A method of growing a water insoluble native plasma oxide on an In0.53Ga0.47As layer of the type that is useful in the fabrication of MOS type devices is disclosed. Oxygen is bubbled through a water chamber in order to introduce water vapor into the growth chamber during the growing process.  The InGaAs layer is first sputter etched in the oxygen plasma while a negative potential is applied to the semiconductor structure.  The pressure is then increased and the oxides are grown while a positive potential is applied to the semiconductor structure.

Abstract: ABSTRACT OF THE DISCLOSURE   A method and an apparatus are disclosed for identifying an individual through a combination of both speech and face recognition.  The voice signature of an interrogated person uttering a key word into a microphone is compared in a pat-tern matcher with the previously stored voice signature of a known person utter-ing the same key word to obtain a first similarity score.  At the same time, when a key event in the utterance of the key word by the interrogated person occurs, a momentary image of that person's mouth region onto which a grid pat-tern has been projected is optically recorded and compared with the previously stored corresponding momentary image of the same known person to obtain a second similarity score.  The two similarity scores are analyzed to verify that the identity of the interrogated person is that of the known person.

Abstract: DELINEATED CEILING GRID IN SUSPENDED CEILING          ABSTRACT OF THE DISCLOSURE          A ceiling runner is disclosed for use in a ceiling grid system of a suspended ceiling.  Each of the main and lateral runners of this ceiling grid system has a similar shape in the flange at the lower end of a generally T-shaped structure.  Such flange has first and second flange portions on each side of the web portion, and these flange portions are joined to the web portion by first and second connector portions which are recessed toward the web portion.  This establishes a longitudinal recess in the exposed surface of the flange so that a distinctive appearance of the ceiling runner is provided which has definite longitudinal delinea-tion between the ceiling panels.  Preferably, the connector portions are shaped to maintain a panel in its proper cen-tered position or to cam such panel to such centered posi-tion.

A guide track member is pivotally connected at its upper end to the horizontal leg of the frame and is engaged with a roller on the lift arm to guide the movement of the lift arm.  A power lift cylinder is pivotally connected at its upper end to the horizontal leg of the frame and is pivotally connected at its lower end to the end of the lift arm opposite from that upon which the gripping means is mounted.  The power cylinder when energized will move the lift arm between a position for gripping a container when in a standing position and a position wherein the container is inverted for dumping its contents into a refuse vehicle.  A power track cylinder is pivotally connected at one end to the vertical leg of the support frame and pivotally connected at its other end to the guide track member.  The power track cylinder when energized will move the lift arm so that the end thereof on which the gripping means is mounted will move laterally in a direction substantially horizontal to the surface upon which the container is standing.

Abstract: ABSTRACT OF THE DISCLOSURE:         Apparatus for local expansion shaping in a pre-cisely located region of the running part of a cylindrical tubular wall of substantial length which comprises a dis-mantable tubular die which includes an expansion chamber and, on respective sides of said chamber, two cylindrical bearing surfaces whose inside diameter is substantially equal to the outside diameter of the tube to be expanded, taking into account the clearance required to permit the tube to be introduced into the die, the bearing surfaces having different coefficients of friction with respect to the surface of the tube to be expanded.  A mandrel which is slightly smaller in diameter than the tube which is to be expansion-shaped is housed within the tube and penetrates into the part thereof which is disposed within the die; it comprises an internal conduit which is substantially parallel to the axis and which may be connected to an ex-ternal pressure fluid source.  By virtue of a radial aper-ture, the conduit communicates with the annular space between the mandrel and the tube.  That space is defined by two regions in which a seal is made as between the mandrel and the tube, on respective sides of the expansion chamber, at the location of the cylindrical bearing surfaces of the die.  The sealing effect is in most cases attained by means of sealing joints such as metal or elastomer seals.  And a process for expansion shaping of at least one localized region in a running portion of the wall of a tube of sub-stantial length.

Abstract: ABSTRACT SIGNAL DETECTION CIRCUIT A ring-trip detector circuit is disclosed which detects a subscriber off-hook condition in the presence of a ringing signal.  The ring-trip detector employs substantially all low-voltage components which enables it to be fabricated using integrated circuit techniques with the resultant cost  and space-saving advantages inherent therein.  The ringing signal is disabled upon detection of a DC component which is present in the telephone loop only when the subscriber goes off-hook.  This circuit detects the DC voltage component across a resistor (20) in series with the ringing source (19) and the telephone loop (12,13).  The voltage across this resistor (20) is converted by resistance networks (23,24) into two relatively small currents that are fed to low impedance points (25,26).  A difference current is formed therebetween, which is filtered (31,45) to remove AC components, and compared with a threshold current (29, 46).  Ring-trip occurs when the filtered difference current exceeds the threshold.

Abstract: NUCLEAR MAGNETIC RESONANCE APPARATUS HAVING SEMITOROIDAL RF COIL FOR USE IN TOPICAL NMR                AND NMR IMAGING     ABSTRACT OF THE DISCLOSURE An improved nuclear magnetic resonance (NMR) apparatus for use in topical magnetic resonance (TMR) spectroscopy and other remote sensing NMR applications includes a semi-toroidal radio frequency (rf) coil.  The semitoroidal rf coil produces an effective alternating magnetic field at a distance from the poles of the coil, so as to enable NMR measurements to be taken from selected regions inside an object, particularly including human and other living sub-jects.  The semitoroidal rf coil is relatively insensitive to magnetic interference from metallic objects located behind the coil, thereby rendering the coil particularly suited for use in both conventional and superconducting NMR magnets. The semitoroidal NMR coil can be constructed so that it emits little or no excess rf electric field associated with the rf magnetic field, thus avoiding adverse effects due to dielectric heating of the sample or to any other interaction of the electric field with the sample.

Abstract: ABSTRACT          This invention relates to a wear means, which is arranged within a rotary drum barker as a wear protection of the drum mantle and is connected with this by means of a bolt joint.  In rotary drum barkers the regions where discharge openings for the bark are arranged are subjected to a heavy wear.  Therefore the wear means of the invention are preferably arranged in these areas.  What characterizes the wear means of the invention is that it comprises a wear body of wear-resistant rubber and a prestressing means which is connected to the wear body so that it absorbs forces.  Moreover, the wear means has  a sleeve-shaped central portion in connection with the prestressing means, the central portion extending into a hole in the drum mantle of a bolt included in the bolt joint and surrounding this.
