Abstract: An apparatus for washing body waste bags that have an opening. The apparatus includes a diverter valve having an internally threaded spout to attach to a faucet. The diverter valve has a plunger and a reduced size nipple adapted to be received in a small opening in a body waste bag. When the faucet is turned on and the plunger is in an diverter open position, the water from the faucet flows normally through the diverter valve for regular use into the bag to wash the bag. When the plunger is in a closed position the water flows through reduced size openings to wash the bag. The diverter valve will remain on the faucet for convenient later use for cleaning body waste bags.

Each said second end of each said headwalk float being attached to a finger float by means of a vertically extending pin means.
Abstract: An apparatus and method of burning trash containing aluminum in a furnace having a moving grate and inclined trays. The grate has an upper and lower part. The inclined trays are provided with one or more inclined plates. The inclined plates are supported on the trays below the upper part of the grate and above the lower part of the grate. Ash and molten aluminum falls through the upper part of the grate, onto the inclined plates, the ash slides off the plates and the aluminum remains on the plates. The plates have holes therethrough to allow air flow for combustion. Some blockage of the holes by aluminum will result over time, but not enough to significantly restrict the flow of combustion air to the combustion area. The trays are removed through the side walls of the furnace for removal of the aluminum when necessary.
Abstract: A combination ornament in the form of a flower and a sprinkler head is provided. The flower is made up of petals and is swingably supported on the sprinkler head. A piston in the sprinkler head is actuated by a water supply which moves the piston upward to move the petals downward out of line with the sprinkler head. A spring is provided in the sprinkler head for forcing the piston downward when the water supply is shut off, for moving the piston and the petals to a closed position.
Abstract: A magnetic trap made up of a hollow, generally cylindrical body, having an open top, an inlet and an outlet for connecting to a flow line for liquid containing entrained removable magnetic material. There is a removable cover for the hollow body, a plate is supported on the cover, and elongated, spaced non-magnetic tubes are fixed to the cover. Elongated stacks of permanent magnets are attached to the plate and extend through the cover into the tubes. When magnetic material held to the tubes by the magnets is to be removed, the cover can be removed from the body, the magnetic stacks can be pulled out of the non-magnetic tubes with the plate, thereby removing the magnetic fields from the tubes so that the magnetic material held to the tubes falls off of the tubes, thereby cleaning the tubes.
Abstract: A delivery signal system and device and method of delivery indication to indicate the location for a delivery to be made. The delivery signal device includes a polymeric transparent film having indicia thereon. Adhesive holds the delivery signal device to a delivery container. In a preferred embodiment of the invention the delivery signal device includes a paper backing and a polymeric transparent film having an electrostatic charge and indicia thereon formed by a luminescent coating. The electrostatic charge is effective to hold the polymeric transparent film and paper backing together. Adhesive holds the paper backing of the delivery signal device to a delivery container. A release coating on the paper backing on the side facing the adhesive allows the delivery signal device to be readily separable from the delivery container. In use the delivery signal device is removed from the delivery container, and the delivery container is discarded.
Abstract: A photo development apparatus made up of a development tank and a heater tank having an immersion heater in the heater tank. A flow means connects the development tank to the heater tank and a manifold connecting the heater tank to the development tank by means of a direction control means including a fitting directed at about 5 to 15 degrees to a radial line from opposite sides of the development tank so that an interference laminar flow is created in the development tank thereby providing agitation.
Abstract: A simple form of woodwind instrument of the clarinet-type and flute-type is shown. Each instrument utilizes the same body made of PCV pipe and different sound generators of clarinet-type mouth pieces or flute-type head joints designed to fit the body. The instrument is intended for beginners in a general music classroom setting grades 1 through 6, possibly complementing the "Orff instrumentarium" of percussion instruments. The simplified instrument may be used along to provide "hands-on" introduction to the legitimate woodwind instruments (clarinets and flutes) in a step-by-step preparation for playing these instruments.
Abstract: Needlepoint sheet having channel perforations with octagonal upper and lower openings. Thread drawn through a channel in a diagonal direction is pulled over a flat surface which widens the area covered by the thread. The needlepoint sheet is made of a polymeric material. The perforations are preferably formed into a plurality of aligned rows for receiving the thread. Each channel is enclosed by eight sides which form octagonal upper and lower openings. The width of each of the sides is substantially equal. In a preferred embodiment of the invention each of the sides form a plane, and the height of each of the side planes is substantially equal. In a preferred embodiment of the invention each of the side planes merge along a curved portion of the wall. This distributes the stress during bending of the needlepoint sheet, and reduces cracking and breakage thereof. In use thread is extended through the channels.
Abstract: An articulator having an upper frame having an upper arm and a lower frame having a lower arm. A pivot is provided on the upper arm swingably supporting the upper frame on the lower frame. Adjusting mechanism is provided for adjusting the upper arm relative to the lower arm so that a casting supported on the upper arm can be rotated relative to the lower arm or tilted up and down, forward and laterally, as well as swinging the upper casting relative to the lower casting. The dental articulator simulates the operation of human jaws for use in the manufacture of false teeth. An upper frame representing the upper jaw is mounted to a lower frame by a pair of ball and socket joints which may be adjusted to approximate a specific patient's jaw hinge. The adjusting mechanism can include a computer controlled motor for adjusting the upper arm relative to the lower arm in accordance with X-ray data of a patient's jaw structure.

Pairs of swingable arms swingably supported on the false bottom to project marbles toward another entrance and to guard marbles from entering the spaces between the barriers, whereby marbles passing said arms into said pockets are lost to certain players.
Abstract: A screen printing system and method is provided in accordance with the invention by using a circular base, a screen, an article to be printed and ink. The circular base has a planar top face. The circular base supports the article to be printed, such as an item of clothing made from cloth. The screen is held in a planar position by a rigid frame. The plane of the screen is positioned above and parallel to the plane of the top face of the circular base. The circular base has a side face with a groove therein which is adapted to hold a resilient flexible annular member. The resilient flexible annular member evenly holds the article to be printed to the circular base so that no wrinkles are allowed to remain in the article to be printed. If wrinkles were allowed to remain in the article to be printed then the pattern of the design to be printed would be distorted on the printed article. The screen includes a fine mesh cloth of fibrous material, such as, silk or nylon or similar filament.
