Abstract: ABSTRACT OF THE DISCLOSURE This invention relates generally to an electrical contact for use in electrical connector assemblies  and more particularly to a contact assembly having a crimp barrel wherein an inspection aperture in an outer shell is open to the interior of the crimp barrel in order to determine if the conductor has been seated within the barrel to the proper depth.  Where the contact assembly comprises two separate pieces, such as a tubular outer shell and a coaxial inner liner, an inspection aperture must be provided in the liner as well as in the shell  and the apertures must align.  Accordingly, indicia are commonly provided for rotationally orienting the liner with respect to the shell. Providing such indica and then aligning the increases the cost of the contact and complicates its assembly.  The present invention provides a contact assembly having an inner liner which is not indixed with respect to the outer shell but which provides an unobstructed inspection aperture to a closed crimp barrel.  A pair ofinspection holes extend through the shell and a transverse slot is positioned in the liner wall in longitudinal alignment with the two inspection apertures in the shell.  The transverse dimension of the slot along the circumference of the cylindrical liner wall is such that the slot is always aligned with at least one of the inspection apertures in the shell regardless of the rotational orientation of the liner with respect to the shell.

Abstract: ABSTRACT           A process for the isolation and purification of immunologically active polyribosyl ribitol phosphate (PRP), the capsular polysaccharide of Haemophilus influenzae type b. The PRP has been purified with ethanol, Cetavlon (hexadecyl-trimethyl ammonium bromide) and a phosphate containing adsor-bent, hydroxylapatite.  The contaminants (nucleic acid, pro-teins and endotoxins) are removed to the minimum level by a treatment with hydroxylapatite.  Also described is a process for the preparation of a combined vaccine containing the PRP (prepared as forementioned) and B. pertussis antigens. The vaccine elicits anti-PRP antibody and anatipertussis anti-body (as measured by microagglutination) formations in young animals.  This sera with anti-PRP antibody exhibits a strong bactericidal activity.

Abstract: ABSTRACT A nuclear magnetism logging system and method is disclosed in which a surface unit provides power to, control of, and signal reception from a downhole sonde.  The surface unit comprises a source of alternating current power and a switching circuit for applying a sequence of alternating current waveforms from the alternating current power source to a surface transformer, each waveform in the sequence starting and stopping with substantially zero amplitude.  The switching circuit memorizes the starting and stopping polar-ity of the one waveform in the sequence, and starts and stops the next wave-form in the sequence of waveforms with polarities opposite that of the mem-orized starting and stopping polarities of the one waveform in the sequence. The downhole sonde of the system has a transformer, the primary coil of which is electrically connected to the secondary coil of the surface transformer. A rectifier circuit is connected to a polarizing-receiving coil during the polarizing time of the polarizing-receive cycle.  A receiving amplifier is connected to the polarizing-receiving  coil during the receiving time of the polarizing-receive cycle.  Receiver and recording circuits in the surface unit receive and record the downhole signals from the receiving amplifier. Timing circuitry controls a downhole switching circuit for alternating the connection of the polarizing-receive coil to the rectifier and the receiving amplifier.

Filed: 1979-04-27
Granted: 1982-07-27
Abstract: Abstract Disclosed is a method of preparing a resin-containing asbestos diaphragm.  The diaphragm is prepared by depositing asbestos fibers and resin from an aqueous slurry onto a liquid permeable cathode and subse-quently heating the deposited asbestos fibers and resin to cause the resin to bound the asbestos fibers together.  As disclosed, air flow is maintained through the diaphragm until the diaphragm is substantially free of entrained water.  The heated air is maintained at a temperature below the boiling tem-perature of entrained water so as to avoid boiling the entrained water. Thereafter, the temperature of the deposited diaphragm is heated to cause the resin to bind the asbestos fibers together.

SLATER and WADE R. BOWDEN, JR.                    ABSTRACT OF THE DISCLOSURE          An electrical outlet box has electrical power cable entry ports in which one or more closure panels are each mounted adjacent the rim of the aperture along one edge portion only of the panel, the remaining portion of each panel being free and extending substantially across the aperture in a direction angular-ly inwardly from the plane of the aperture.  The closure panels are each either hingedly mounted ox sufficiently flexible and resilient so as to be self-opening, such that each free end portion is deflected away from the opening Upon passage of the cable into the aperture by manual force, and thereafter resist-ingly bears against the installed cable.  Each panel may be tapered so as to have increased thickness at the base, in which case the panels are self-clamping against removal of the cable from the aperture, and may include supplementary cable gripping projections of their outwardly facing surfaces.  The closure panel or panels may also be self-locating and self-adjusting for different cable sizes up to a maximum size equal to the size of the aperture.  Access to the box through the cable entry port may be substantially prevented by a frangible closure member, either as a thin web joining the free end of a single closure panel to the wall structure of the box or joining the free ends of two or more panels together, or as a separate conventional knockout panel frangibly interconnected to the rim of the cable entry aperture.  The closure panel or panels and outlet box also may be formed as an integral structure.
