Abstract: A method and apparatus for collecting and storing urine comprises a collecting funnel and collection tank. The funnel has a valve that opens flow of urine begins and closes once the flow stops based on a flow sensor. The flow time of urine is recorded and used to regulate the evacuation and inert gas filling of a head space in the collection container once the urine is collected. The inert gas protects the urine from oxidation so that degradation is minimized while in the collection container. A similar control can be exercised when a bottle is filled with urine from the collection container, wherein head space in the bottle is filled with inert gas for oxidation protection to form a finished package. The head space of finished package can be evacuated to minimize degradation of the urine once the urine is accessed an initial time in the finished package.

Abstract: The present disclosure relates to systems and methods for creating and maintaining modified and controlled atmospheres (MA/CA) in a rigid sealable container having at least one refrigeration unit with an integrated oxygen reduction structure. The refrigeration unit provides the necessary ambient atmosphere movement for the oxygen reduction structure, such as a hydrogen fuel cell. The systems and methods are useful in the, storage, transport, distribution, processing and packaging of fresh perishables with a focus on altering the natural gaseous environment around the perishables such that fresh shelf-life is extended. The systems may operate in a power generation/power production mode, such that the fuel cells maintain the MA/CA environment while providing both primary and back-up power.

Abstract: Methods for disinfesting insect pests such as the Mexican fruit fly in citrus fruit such as grapefruit with minimal adverse effect on fruit quality include placing and maintaining such fruit for a time period of about 15 to about 21 days at a temperature of about 14° to 18° C. and in a gaseous mixture that includes not more than about 0.05% oxygen by volume, a balance nitrogen or up to 20% carbon dioxide in combination with nitrogen.

Abstract: A saw chain for cutting aggregate material has sealing members to seal the pivotal connection between the center drive links and the rivets to prevent entry of contaminates into the bearing surfaces. In one arrangement, O-rings are mounted in grooves of the tie straps with the O-ring being compressively forced against the center drive link. The O-ring prevents entry of contaminants into the bearing surface between the bore of the center drive link and the rivet. In another arrangement spring type cup washers fit in a groove of the tie straps and the cup washers are biased against the center drive link.

Abstract: An articulated saw chain for cutting aggregate material and the like. The saw chain has cutting blocks affixed to pairs of side links and guards formed or attached to side link pairs positioned between successive cutting blocks. A guard portion is thus adjacent each end of the cutting block. The guard portions extend to substantially the same height as the cutting block to protect the edge of the cutting block from impacting against an object. The guards wear at a rate that does not significantly impede or interface with the cutting action of the cutting block.

Abstract: A chain saw bar nose has a rotatable sprocket. The sprocket assembly is adapted to conform in shape to the drive tang portions of the saw chain whereby the nose sprocket may receive operational forces imposed by the saw chain substantially as compressive forces as opposed to tensile forces. As a result, the nose sprocket assembly better withstands the harsh operating conditions imposed by cutting applications.

Abstract: A chain saw feed mechanism includes an arm pivotally mounted to the chain saw and carrying a dog for pivotally engaging the workpiece at the kerf. Thrusting the chain saw along the longitudinal axis of the guide bar moves the guide bar along an arc concentric to the point of workpiece engagement and thereby cuts laterally through the workpiece. Longitudinal thrusting force applied by the operator transfers via the lever arm into lateral feed force needed for cutting the workpiece. The feed mechanism is particularly useful in aggregate cutting applications, where the chain saw is heavy and large cutting forces are needed to pass the saw through the aggregate.

Abstract: A sprocket nose guide bar for guiding an endless saw chain. A configured sprocket is rotatably mounted in the nose of the bar and functions to elevate and transport the saw chain around the nose end. The teeth of the sprocket engage the drive links of the chain to lift the chain off the nose edge as the chain traverses the nose. The tooth tips project above the side link bearing surfaces and into configured notches whereby the teeth effectively provide the lifting action without entering the saw chain chassis.
