Abstract: A modular rotating carousel assembly for storage and unspooling of pipe or cable is provided that comprises a plurality of triangular subassemblies; each triangular subassembly comprises a base member and at least one pair of connecting members; the connecting members are connected together at one end to form an apex and are connected at the other end to the base member; the base members of the plurality of triangular subassemblies are rotatably connected together to form a first circle; wherein the apexes of the connecting members extend outwardly from said first circle; and a plurality of rotating caster members is positioned beneath the rotatable connection of a plurality of said base members. Additional sets of triangular subassemblies are built up on concentric circles until the desired size of carousel is formed. A drive mechanism is provided that includes a motor that rotates a perimeter drive chain that engages sprocket pads spaced about the circumference of the carousel.

Abstract: A modular filter system using replaceable filter cartridges includes a locking arrangement that prevents rotation of the flow control valve spindle in the filter head, but includes an unlocking arrangement on the cartridge that unlocks the locking arrangement if the proper replacement cartridge is used. The locking arrangement may include spring biased locking pins carried on the filter head and matching unlocking pins on the filter cartridge to operate through an intermediate adaptor ring that is set on assembly to match the positions of the locking and unlocking pins.

Abstract: A utility cart is presented having improved assembleability, economy, rigidity and stability. In one feature, the cart includes a wheeled frame having a shelf supported by the frame. The shelf includes a movable surface and the frame includes a retention surface. The movable surface moves between a position of out of engagement with the retention surface and a position in engagement with the retention surface. This structure allows the shelf to snap into place without the need for separate mechanical fasteners. According to another feature, the cart includes a top shelf configured to deflect U-shaped leg members inward to apply a binding force upon the bottom shelf. According to a third feature, the cart includes a cross member connecting two leg members, the cross member having L-shaped slots to receive protuberances on the leg members.

Abstract: A covered food serving pan is provided having a food pan from which a flange with tab retainers extends, and a cover with tabs extending from an edge. These tabs engage tab retainers on a flange of the food pan and allow the cover to rotate with respect to the food pan. A method is provided for attaching a cover to a food serving pan by sliding the tabs toward the tabs retainers and engaging them with the tab retainers, rotating the cover about the tab retainers along a first axis of rotation, translating the cover in a direction parallel to the axis of rotation, and again rotating the cover about the axis of rotation until the open end of the pan is covered.

Abstract: A sunken receptacle unit for insertion in an opening of a counter having a top surface and a bottom surface includes a receptacle having a bottom and a plurality of walls defining an interior cavity, a receptacle support surface extending outwardly from the walls for supporting the receptacle within the opening and a receptacle retaining surface coupled to one of the walls. The receptacle retaining surface moves between a first position beyond the opening for engaging the bottom surface of the counter and a second position within the opening for insertion of the unit through the opening. The receptacle retaining surface is resiliently biased in the first position.

Abstract: A method and associated tool joins all types of parted wire fencing material. The method and tool allow one person to quickly create a permanent splice that unites the parted wire while restoring tension to the parted wire lengths. Following the method, the tension remains when the tool is released from the splice. The result is a taut splice, with no sag or slack.

Abstract: A handle assembly includes an open-ended sleeve connectable to a valve stem by a screw inserted and removed through the open end. A removable cap has four cross openings which align with four cross openings in the sleeve. Two cross members are placed in the cross openings and interfitted inside the sleeve. In one embodiment, the internal connection is provided in part by a hole in one of the cross members. In a preferred embodiment, the cross members have contacting surfaces for engaging the sleeve and the cap. The handle assembly is adjustable for use with a variety of sleeves.
