Abstract: A backspin retarder for a progressive cavity pump deploys on the drive string uphole from a pump unit. The backspin retarder has a shaft that connects to portions of the drive string. An impeller disposes on the shaft and can move axially and radially. In an unengaged condition, the impeller and shaft can rotate relative to one another so the drive string can rotate in a drive direction without impediment from the impeller. In an engaged condition, the impeller rotates with the shaft in a backspin direction. In this way, vanes on the impeller can retard the backspin of the shaft and drive string by attempting to force the lifted fluid column flowing downhole past the impeller back uphole. The retarder can use a pin and slot arrangement or an arrangement of engageable teeth to engage the impeller to the rotation of the shaft.

Abstract: Weather-resistant charcoal bags are formed from a woven thermoplastic layer and optionally having a barrier film layer. The charcoal bags can also have a flat bottom for improved advertising.

Abstract: This invention generally relates to compositions and method of producing diluted hypohalous acid and hypohalous acid vapor. These compositions can be used to treat allergen containing surfaces, hard surfaces, food contact surfaces, hospital surfaces, food surfaces, kitchen surfaces, bathroom surfaces, human surfaces, animal surfaces, children's items, outdoor surfaces, soft surfaces, and medical instruments. These compositions can be converted to solid particulate or granular compositions. These compositions can be put into a variety of containers which preserve the stability. These compositions can be used to treat allergens and molds and as part of a mold detection system. These compositions can be dispersed into the air to enable microbiological control.

Abstract: The present invention provides a thermoformed litter scoop comprising a generally concave scoop portion, and a handle portion attached to the scoop portion. The scoop portion has a bottom, sides and a rear and a plurality of openings therein. The openings are defined to allow the passage of litter granules therethrough. The handle portion has reinforcing ribs and the scoop portion has reinforcing ribs. The invention also describes a method of making a thermoformed scoop.

Abstract: This invention relates to methods and apparatus for achieving microbiological control, especially using active sources that generate hypochlorous acid vapor. These methods are effective in confined spaces and sealed containers. The active sources may be contained within permeable containers and may be actively dispersed. The active sources may be in the form of solids, liquids or gels.

Abstract: This invention relates to methods and apparatus for achieving microbiological control, especially using active sources that generate hypochlorous acid vapor with reduced levels of chlorine vapor. These methods are effective in confined spaces and sealed containers. The active sources may be contained within permeable containers and may be actively dispersed. The active sources may be in the form of solids, liquids or gels.

Abstract: The invention provides a container for containing pourable materials, said container including a container body having at least one wall, the wall extending from an end panel; the container body having an at least partially engirdling portion, and the engirdling portion forms at least one grip.

Abstract: The invention provides a process, and an article of manufacture, in which a blown, hollow plastic article which has a paper label applied by in-mold labelling, must have the label positioned such that the longitudinal fibers thereof are oriented substantially with respect to the longest axis of the blown, hollow plastic article.
