Abstract: A sigma-delta analog to digital converter 1 is disclosed .         The digital filter comprises a digital integrator (8, 10) for reception of  the negative  feedback  signal  of  the analog modulator.  The digital integrators (8, 10) are connected to replicate processing of the feedback signal by the analog integrators (3, 5).

Title: Spinel-carbon refractory
Inventor: KNAUSS RICHARD J
IPC: C04B35/66
Filed: 1991-10-16
Abstract: SPINEL-CARBON REFRACTORY            ABSTRACT OF THE INVENTION      The problems associated with the low thermal shock resistance of conventional refractories utilized in continuous casting operations are overcome by a spinel-carbon refractory which provides improved thermal shock resistance.  The spinel-carbon refractory of the present invention includes either a sintered spinel, a fused spinel, or a mixture of sintered and fused spinel in combination with a source of carbon, such as flake graphite.  Spinel (magnesium aluminate, MgO.Al2O4) imparts into the resultant refractory a lower overall thermal expansion which improves the thermal shock resistance of the shape.  Minor additions of alumina, magnesite, zirconia or combinations of these materials can be added to the spinel based mix of the present invention without significantly compromising the overall decrease in thermal expansion of the base mix.  Additionally, metallic additions, such as aluminum, silicon, magnesium, or various alloy mixtures can be added to the base mix to enhance oxidation resistance and hot strength.  It is believed that magnesia-enriched spinel, stoichiometric spinel (72 wt. % alumina and 28 wt. % magnesia), and alumina rich spinel can be used with equal or near equal results. The spinel grain used in the spinel-carbon refractory of the present invention should be free of impurities, that is, it should contain less than 1 wt. % lime and less than 2 wt. % silica.

Abstract: Treatment and diagnosis of P. aeruginosa infection or colonization is achieved in accordance with this invention by the discovery of a polypeptide which is smaller than the naturally occurring P.  aeruginosa pilin protein. The pure polpeptide com-prises at teast one amino acid residue sequence containing about twelve amino acid residues and up to about twenty amino acid residues that define a sequence capable of immunologically mimicking an antigenic determinant site of P. aeruginosa pilin. This amino acid residue sequence can repeat as a unit one or more times in the same polypeptide motecute. More than one of such re-peating units and more than one repeating unit of the same type can be present in a single polypeptide molecule: The polyep-fides act as antigens or immunogens and antibodies may be raised to the immunogens and a vaccine prepared suitable for the prevention of P. deruginosa infection:

Abstract: RD-20,352 QUALITY ASSURANCE OF SURFACE TREATMENTS    BY ANALYSIS OF SUBSTRATE SURFACE         LINE TRACES                 Abstract of the Invention A quality assurance of surface treatments, typically with shot peening, by analysis of substrate surface line traces is disclosed. In particular, line traces are created over the surface treated substrate. These line traces are filtered with a low pass filter to create relative maximums. The coordinates of the relative maximums are determined and the spatial distance between these coordinates are measured and recorded. The actual plastic upset depth of the surface treatment substrate is determined. The surface treatment is then adjusted, if necessary, based upon the values of these spatial distances and actual plastic upset depths..
