Abstract: A harness assembly for a backpack includes a pair of straps, a pair of right angle cinch rings, and a buckle. The right angle cinch rings allow the straps to be tightened on the chest of the wearer by pulling on the strap ends which are around the wearer's waist and fastening the buckle. The right angle cinch rings maintain the tightness of the straps on the wearer's chest when the buckle is loosened, preventing the pack from sliding down the wearer's back.

Abstract: A hybridoma cell line produces an antibody with reactivity directed specifically to immunodominant antigens from the catfish pathogen Edwardsiella ictaluri, the antigens having molecular weights of about 14,000, 39,000, 48,000, 60,000, 66,000, 83,000, and 93,000 daltons. This antibody is specific for proteins of E. ictaluri but not for other catfish pathogens. It is therefore useful for the positive identification of E. ictaluri from body fluids and tissue of catfish and for identification and purification of the reactive immunodominant antigens.

Abstract: A point mutation in the CD18 gene responsible for causing bovine leukocyte adhesion deficiency (BLAD) and a silent mutation linked thereto have been identified. Nucleic acid sequences encompassing these mutations serve as bases for testing and identifying cattle alleles attributable to BLAD using any of a variety of diagnostic assays. Suitable nucleic acid probes and primers have also been designed for use in such assays.

Abstract: Amylodextrin compositions are produced from starch hydrolysates having a dextrose equivalent (DE) less than 10 or from milled substrates such as cereals, oilseeds, and vegetable fibers. The compositions give aqueous gels with unexpectedly increased strengths and improved fat-sparing characteristics, including more desirable flavor and texture qualities. The amylodextrin compositions are segregated from hydrolyzed aqueous cereal flour or starch hydrolysate solutions, for example, by precipitation with the proper amount of a water-miscible organic solvent, such as ethanol, acetone, or 2-propanol.

Abstract: Regions in the pseudorabies virus genome in the unique long region and the internal repeat sequence contain nucleotide sequences which are unique to latent infection of the virus. These regions are the basis for constructing nucleic acid probes and antigens useful in distinguishing latent pseudorabies infection from productive infection.

Abstract: Single-stranded DNA probes complementary to a hypervariable region of Campylobacter 16S rRNA are useful in distinguishing species of this pathogen from one another. The probes find practical application in diagnosing human and animal diseases caused by this organism from clinical samples, such as fecal material. They are also useful in differentiating Campylobacter species based on RFLP analyses.

Abstract: A finger is provided on the backshell extension of a heavy duty multi-pin connector to provide an attachment point for a strain relief band. The strain relief band prevents strain on a conductor bundle in response to flexure of a protective hose which is mounted on the backshell extension. The strain relief band may be similar in construction to the hose band which is used to secure the protective hose on the backshell extension.

Abstract: Diagnostic reagents comprising the 20 kd Brucella abortus CuZn superoxide dismutase (B. abortus lCuZnSOD) protein and peptide segments thereof, which are effective as antigenic determinants, have been identified. These reagents are useful for detecting an antibody response to the B. abortus CuZnSOD protein in bovine serum or other body fluid samples and can also be used for distinguishing between animals which have serum antibody of a natural B. abortus infection and those which have an antibody response to a B. abortus Strain 19 vaccine or a B. abortus Strain which does not express the 20 kd protein.

Abstract: Biologically active agents to be encapsulated are continuously blended with a starchy material and water, subjected to high-shear mechanical action at a temperature above the gelatinization temperature of starch, and continuously recovered as an insolubilized matrix of starch that entraps discontinuous domains of the agent. Alternatively, the core material to be encapsulated is added and blended with the aqueous dispersion of starch after the starch and water have been subjected to an elevated temperature sufficient to gelatinize the starch. Rate of release of agents to the environment can be controlled by preselecting a set of conditions related to various processing parameters. Encapsulation of biologically active compositons provides protection against degradative environmental conditions, improves safety in handling, and slows the release of such compounds to the surrounding medium.

Abstract: A high altitude G-valve produces a pressure signal in response to altitude and G-load without a connection to an external altitude sensing device. Bleed path pressure regulation by an aneroid valve and a G-sensing valve control a pilot valve which in turn controls a main valve. The main valve provides regulated air to the G-valve outlet in response to the pilot valve. A manually actuated button simulates a high-G load on the G-sensing valve to test the operation of the device.

Abstract: A printed circuit board connector includes a daughterboard connector and a pin header. The daughterboard and pin header contacts are secured in their respective housings by interference nibs which are mounted on resilient portions of the contacts. Various constructions are disclosed for separating contact from a carry strip by means of a weakened break-line which will secure the contact to the carry strip during post-manufacturing operations and will form a sharp V-shaped tip when the contact is intentionally removed from the carry strip.

Abstract: Intact X and Y chromosome-bearing sperm populations of rabbits and swine were separated according to DNA content using a flow cytometer/cell sorter. Sperm viability was maintained by special staining techniques and by sorting and collecting the sperm in nutrient media. The sorted sperm were surgically inseminated into the uteri of rabbits or swine. Of the offspring born from does inseminated with the sorted population of X-bearing sperm, 94% were females. Of offspring born from does inseminated with sorted Y-bearing sperm from the same ejaculate, 81% were males.

Abstract: The combination of monoclonal antibodies 11A25 and 11E32, which recognize two distinct antigenic sites on the 62-kd glycoprotein of reticuloendotheliosis virus (REV) in ELISA, enables an increase in the sensitivity of an ELISA assay for subtype 2 REV over what was heretofore possible. The combination of MAbs is useful for diagnosing REV antigen and antibody in poultry flocks and for detecting new strains and variants of the viral subtype.

Abstract: An LCD has both active and passive display areas. The active areas are presented by selective energization of dichroic liquid crystal, and the passive areas are created by a mask. The LCD cell includes a sealed cavity containing the dichroic liquid crystal which has an area substantially less than the total display area. The remaining portion of the LCD cell is free of liquid crystal and is transparent to the passage of light from a rear light source.

Abstract: Moisture is removed from the compressed feed air to a separator and collected in liquid form in a reservoir. The humidity in a controlled atmosphere container is monitored and moisture is taken from the reservoir and added to the container in order to provide an ideal environment for the preservation of foodstuffs.

Abstract: Printing inks, which do not require any petroleum-derived component, are prepared from vegetable oils by heat bodying the oils to within a specified viscosity range. The process is easily tailored to give products having viscosity, tackiness, ruboff resistance, and color density properties which meet or exceed industry standards. The inherent light coloration of the vehicles permits formulation into colored inks having substantially reduced pigment levels.

Abstract: Disclosed are DnA sequences which code for antigenic proteins, methods for identifying such DNA sequences, and antigens coded for by such DNA sequences.The first step of the method is to provide a multiplicity of DNA sequences. These sequences are then inserted into DNA expression vectors to form recombinant expression vectors. The expression vectors are inserted into suitable hosts to form transformants which express the DNA sequences. The transformants are then contacted with antibodies directed against Eimeria antigens to identify transformants containing DNA sequences which code for Eimeria antigens. These antigens are then produced from the DNA sequences identified as coding for the antigens. The antigens so produced are contacted with white blood cells which effect a cell-mediated immune response, which white blood cells are sensitized to an antigenic Eimeria protein, to thereby identify DNA sequences which code for antigens that induce a cell-mediated immune response to avian coccidiosis.

Abstract: The levels of essential metals in the mammalian system can be precisely controlled by administering these metals in the form of exogenously synthesized coordination complexes of picolinic acid. The complexes are characterized by the following structural formula: ##STR1## wherein M represents the metallic cation and n is equal to the cation's valence.
