Abstract: A cart for filling intermodal shipping containers with a bulk particulate material, such as grain, includes a hopper to receive the bulk material and a belt conveyor to deliver the material to the container. The conveyor is positioned external of the container and throws the material along an arcuate path to the opposite end of the container whereby the container is substantially filled without the need to extend the conveyor into the container. The cart is supported on wheels to be moved where needed. The cart can straddle a standard truck trailer carrying a container so that the container need not be removed from the trailer for filling. The conveyor height is variable to reach a container on a truck trailer or on the ground. The cart width can also be reduced for road transport.

Abstract: An apparatus for transporting and filling a freight container, such as an ISO standard intermodal container, with grain or other crop at the point of harvest. The apparatus includes a chassis adapted to support the freight container and a hopper for receiving grain from a harvesting machine. A conveyor moves the grain from the hopper and into the container. The apparatus is pulled by a tractor or can be a self propelled vehicle to move the container through a field to the harvester to receive grain and fill the container while the harvester continues to move through the field harvesting grain.

Abstract: This invention relates generally to an assay for Lyme disease which detects the antibody to Borrelia burgdorferi, the causative agent of Lyme disease. More specifically, the assay employs antigens derived from amino acid regions in the flagellum of Borrelia burgdorferi. These antigens are immunoreactive with antibodies to Borrelia burgdorferi but are not substantially immunoreactive with antibodies to Treponema pallidum, the syphilis causing agent. DNA sequences of the antigens, clones and vectors containing the DNA sequences are also disclosed. Polypeptides derived therefrom can be used as reagents for the detection of antibody to Borrelia burgdorferi in the body fluids from individuals with Lyme disease.

Abstract: A method for treating biological samples, e.g., human sera or plasma, suspected of containing rheumatoid factors to eliminate cross-reactivity and false positive assay results in IgM immunoassays that are caused by the presence of rheumatoid factors in these biological samples. In one aspect, the method comprises diluting a biological sample with a sufficient amount of rheumatoid factor neutralization buffer to cause the pH of resulting reaction mixtures containing this sample and a solid phase material to be sufficiently low to cause rheumatoid factors in those mixtures to reduce their affinity to IgG antibodies to such an extent that they will not form a complex with IgG antibodies bound to the solid phase material, thereby facilitating the removal of these rheumatoid factors from the mixtures prior to the detection phase of a diagnostic assay.

Abstract: Preparation of bromofluoromethane may be effected in good yield by reductive debromination of dibromofluoromethane using an organotin hydride, for example tri-n-butyltin hydride.

Abstract: An audio power amplifier for general audio and sound reinforcement use, or musical amplification, stringed or otherwise, which combines the sonic properties of vacuum tube amplification with the modern technology of solid state electronics, with its attendant advantages.

Abstract: A pre-amplifier for musical instrument audio signals which utilizes a solid state programmable logic device to control a plurality of solid state switches for routing the audio signals in preselected manner through successive stages of vacuum tube amplification.

Abstract: A liquid .beta.-streptococcus selective medium for the growth and detection of .beta.-hemolytic streptococci without allowing the growth of enterococci and other non-.beta.-hemolytic streptococci, consisting essentially of 0.2-0.4 gm. pullulan as carbohydrate source based on 93-72 ml water, a protein source such as a combination of Proteose Peptone #3, (a dried meat digest) and Biosate (pancreatic digest of casein combined with yeast autolysate), an inhibitor of the growth of Pseudomonas, such as thallous acetate, an inhibitor of the growth of gram negative organisms other than Pseudomonas, such as nalidixic acid, an inhibitor of the growth of staphylococci such as Gentamycin, and reduced aniline blue indicator.

Abstract: In a receiver arrangement for a quadrature phase-shift digital data transmission system including an adaptive equalizing regenerator, a phase control signal for the local oscillator is derived from an output of the regenerator and decision feedback signals within the regenerator are applied by way of balanced current switching circuits.

Abstract: (6R,7R)-7-amino-3-(1-pyridiniummethyl)ceph-3-em-4-carboxylic acid monoperchlorate is a useful intermediate in the preparation of (6R,7R)-7-amino-3-(1-pyridiniummethyl)ceph-3-em-4-carboxylate dihydrochloride by enzymatic deacylation of 7-amino-3-(1-pyridiniummethyl) cephalosporin compounds and may be isolated in a substantially pure crystalline form. The said dihydrochloride and its solvates may be used as intermediates in the preparation of a wide range cephalosporin compounds.

Abstract: An apparatus for testing enclosed electromagnetic relays includes a probe displaceable into the relay enclosure to engage the movable contact thereof. The probe is associated with a force transducer and a displacement transducer which provide inputs to a circuit including microprocessor unit which operates to detect the probe force required to break contact between the movable contact and the normally closed contact and to detect the position of the probe when such break occurs and when the normally open contact is made and to calculate the contact travel from the position signals it receives. Contact over travel is also measured by applying current to the relay winding and measuring probe displacement required to re-engage the contact.
