Abstract: A water treatment system for a poultry chiller including a chiller tank is described herein. The system includes a float holding tank at a downstream section of the chiller tank; a fan at the downstream section of the chiller tank that is configured to blow float formed on a surface of the water in the chiller tank into the float holding tank; and a float removal mechanism at the float holding tank that is configured to remove the float from the float holding tank. Related methods are also described.

Abstract: An improved string trimmer head is described. The trimmer head comprises a housing with a spool and spring assembly enclosed within the housing. The trimmer head further comprises a lid connected to the housing and a bump knob with a base and an intermediate member. The base of the bump knob is located inside the housing. The intermediate member extends outside the housing through the lid. The lid comprises an annulus which surrounds the base. The height of the annulus is greater than a maximum compressing distance of the spool when compressed by the bump knob. A segment of the intermediate member remains outside the lid when the spool is compressed. The bump knob further comprises a finger slot with an outer edge and a recessed portion. A bottom side of the outer edge is positioned farther away from the spool than the recessed portion.

Abstract: A carburetor with a housing defining an air intake and fluidly connected to a throttle system is provided. A rotatable choke is connected to the carburetor and includes a plate with an inlet aperture in fluid communication with the air intake. A dial is rotatably mounted to the housing and surrounds a portion of the plate. The dial substantially blocks the inlet aperture when in a first position with respect to the plate, and the dial exposes the inlet aperture when in a second position with respect to the plate.

Abstract: A table leg supporting a table top vertically above the floor is adjustable between minimum and maximum heights and adapted to receive a castor at the lower end thereof. The castor alters the minimum height of the table leg to be greater than the maximum height of the table leg without the castor. A spacer is removably mounted on the lower end of the table leg without a castor for increasing its height to be at least equal to and preferably greater than the minimum height of the table leg with a castor. Thus, tables supported by legs with castors can be positioned adjacent tables supported by legs without castors, and the adjacent tables can be adjusted to the same height by adding spacers to the non-castored legs.

Abstract: A top cap arrangement for an interior space-dividing wall panel arrangement which mounts on and projects upwardly from a floor for dividing a floor area into a plurality of smaller working areas. The panel arrangement is defined by a plurality of individual panel members which are less than ceiling height, and have an interior frame construction which includes an elongate top frame element which extends along and defines the upper surface of the panel member. A top cap member mounts on and extends horizontally along the top frame element, and is constructed of a material which permits at least limited transverse flexibility. The top cap member has a channel-like configuration which includes outer side flanges which slidably overlap and embrace exterior sides of the panel member to permit at least limited vertical positional adjustability of the top cap member relative to the panel member.

Abstract: Stackable and connectable foam building blocks include pairs of parallel side walls and opposite end walls extending between ends of side walls and multiple transverse members extending between the side walls at regular intervals. Each end wall has a U-shaped cutout section at its top to allow concrete flow between cavities of adjacent blocks and for supporting rebars. The upper edge of the end wall defining the lower part of the U-shaped section gradually increases from the outer surface to the inner surface of the end wall to form a downward and inward sloping surface for the lower part of the U-shaped section. Each transverse member includes a pair of structures substantially identical to the end walls. The two structures are positioned back-to-back, such that each cutout surface slopes inward and downward from the middle of the transverse member towards the adjacent cavity and a ridge is formed where the two sloping surfaces meet.

Abstract: A foldable valance having plastic hinges attaching the return panels to the front panel of the valance, to allow folding of the return panels alongside the front panel for compact packaging. A tab is formed integrally with one of the plate portions of the plastic hinge and is movable to a position extending at an angle to the associated plate portion of the hinge, for retaining the return panel in erected condition when the valance is installed.

Abstract: Conventional drag bits for diamond insert studs generally require a two-step operation which includes a first drilled hole to accept the grip length of the diamond stud. A second counterboring operation relieves the upper portion of the bored hole to clear the bottom edge of the diamond cutting face of the insert. Counterboring also facilitates insertion of the studs within the hole. Conventional insertion methods for the studs unfortunately leave a portion of the insert vulnerable to breakage because the back side of the insert opposite the cutting face is unsupported. This invention corrects this problem by drilling the counterbore hole eccentrically with respect to the insert hole so that the counterbore surface is, for example, tangent with the insert hole at a point opposite the cutting face of the insert stud, thus providing support for the upper portion of the stud during operation of the drag bit.
