Abstract: A tool for repair and maintenance of a rail extending about the perimeter of a bed, the rail separated from the bed by a predetermined distance. The tool comprises a shaft with first and second sides. The first side has a curved surface, and the shaft has a cross-section normal to the curved surface with a maximum width that is less than the predetermined distance. A flange extends from the second side, the combined shaft and flange having a cross-section normal to the curved surface with a maximum width that is at least the predetermined distance.

Abstract: Systems, methods, and computer-readable media are disclosed for passive throttling of bulk material on conveyor systems. In one embodiment, an example system may include a first conveyor having a first width, a second conveyor having a second width, the second conveyor disposed adjacent to the first conveyor, a third conveyor disposed adjacent to the second conveyor, a chute, and a fourth conveyor. Items falling from the second conveyor may be guided to the fourth conveyor via the chute. The first conveyor, the second conveyor, and the third conveyor may move in a first direction, and the fourth conveyor may move in a second direction.

Abstract: A singulation device can singulate items. The items can be received onto a singulation conveyor. A portion of the items can be retained on the singulation conveyor by a retaining ledge. The portion of the items not retained on the singulation conveyor can fall onto a return conveyor. The singulation conveyor can transport the retained items along the length of the ledge. During conveyance, some of the items can fall off of the singulation conveyor onto the return conveyor.

Abstract: An inventory-handling system can receive inventory containers filled with inventory items. The inventory containers can be received between guides and advanced through the inventory-handling system. The guides can be curved to rotate the inventory containers being advanced through the inventory-handling system. The inventory containers can be rotated from an upright orientation to an inverted orientation for emptying the inventory items.

Abstract: Methods to prevent ketosis or minimize the effects of ketosis in ruminant animals are provided. This methods include feeding to the animal biotin in combination with a mixture of at least two essential oil compounds selected from the group consisting of thymol, eugenol, meta-cresol, vaniline and guajacol. The methods usefully prevent and/or inhibit ketosis of calving ruminant animals and the subsequent need for veterinary treatment. In a preferred embodiment of a feeding concept for dairy cattle, especially calving dairy cattle, biotin is used in an amount sufficient to provide a daily dosage of 10 mg to 20 mg per head to which it is to be administered. It is at present contemplated that the essential oils are administered in amounts (total dosage ranges of essential oils) of 1 to 1.5 g per head per day.

Abstract: The present invention is made for the prevention of ketosis or minimizing the effects of ketosis in ruminant animals. This purpose is achieved by feeding to the animal biotin in combination with a mixture of at least two essential oil compounds selected from the group consisting of thymol, eugenol, meta-cresol, vaniline and guajacol. The present invention is useful because it is capable of preventing and/or inhibiting ketosis of calving ruminant animals and the subsequent need for veterinary treatment. In a preferred embodiment of a feeding concept for dairy cattle, especially calving dairy cattle, biotin being used in an amount sufficient to provide a daily dosage of 10 mg to 20 mg per head to which it is to be administered. It is at present contemplated that the essential oils are administered in amounts (total dosage ranges of essential oils) of 1 to 1.5 g per head per day.

Abstract: Color shifting retroreflective articles can provide features such as decorative effects, evidence of tampering, security authentication or positional information. In some embodiments, the color shifting retroreflective article includes a layer of microspheres, and a reflective coating that is disposed in optical association with the layer of microspheres. The reflective coating includes a spacer layer disposed between a semitransparent first reflective layer and a second reflective layer. The first reflective layer includes a reflective layer disposed adjacent the layer of microspheres. At least one layer of the reflective coating includes a non-uniform thickness associated with each of a plurality of microspheres such that light incident on the article from a first direction is retroreflected at a first color and light incident on the article from a second direction is retroreflected at a second color visibly different from the first color.

Abstract: A method of making a polymer coating on a microstructured substrate. The method may be performed by vaporizing a liquid monomer or other pre-polymer composition and condensing the vaporized material onto a microstructured substrate, followed by curing. The resulting article may possess a coating that preserves the underlying microstructural feature profile. Such a profile-preserving polymer coating can be used to change or enhance the surface properties of the microstructured substrate while maintaining the function of the structure.

Abstract: An adjustable, sturdy upper body support assembly for keyboard operators includes a pair of adjustable armrests mounted on a rigid frame which can be incorporated into a standalone system or into a workstation system. In one embodiment, the support assembly is positioned adjacent and partially underneath a piece of furniture. The support assembly in this embodiment includes a counter-balance member which is adjustable and can be positioned adjacent an underside surface of the piece of furniture. The piece of furniture interacts with the counter-balance member to prevent the assembly from tipping when the user rests part of their upper body, including their arms, on the armrests. In another embodiment, the assembly includes a support frame and an upper body support apparatus. The upper body support apparatus is movably engaged with the support frame to permit the apparatus to be moved underneath a piece of furniture when not in use.

Abstract: An adjustable, sturdy upper body support system for keyboard operators includes a pair of adjustable arm rests mounted on a rigid frame which can be incorporated into a standalone system or into a desk workstation system. In either embodiment, the frame includes a portion extending forward under the arm rests to prevent the device from tipping. The arm rests can be pivoted about two axes relative to a U-shaped frame slidable within a primary frame underneath a keyboard platform. The standalone version includes outwardly diverging feet for added maneuverability and can be positioned underneath an existing desk. In one version, the upper body support is mounted to a height adjustable desk workstation. Another combined upper body support and desk system includes a height adjustable desk positionable with respect to the arm rests.
