Abstract: A table apparatus has a base, a table affixed to the base, a fan positioned in the base so as to deliver a flow of air outwardly of the base, a motor drivingly connected to the fan, and air plenum formed adjacent to the table, and a plurality of airflow lines extending through the table or along and underside of the table. Each of the plurality of lines has an outlet adjacent a periphery of the table. The outlet of the airflow line is formed at an outer edge surface of the table. A plurality of louvers are adjustably positioned at the outlet so as to direct a flow of air from the outlet.

Abstract: A table umbrella apparatus has a base, a table affixed to the base, a canopy support by the base a distance above the table, and an air treating means positioned in the base for delivering a flow of air outwardly of the base. The air treating system includes a fan, a motor drivingly connected to the fan, a reservoir positioned in the base, and a pump cooperative with the water in the reservoir for passing a flow of water across air urged by the fan. An aspen wood intake filter is positioned in the base so that the air is urged by the fan across this intake filter.

Abstract: A table umbrella apparatus having a base, an umbrella with an inner surface extending therealong, a tubular support affixed to and extending from the base and supporting the umbrella a desired distance above the base, and a fan connected to the tubular support. The fan has a fan blade mounted so as to rotate about a vertical axis. The fan directs air flow at least upwardly toward the umbrella. A motor is connected to the fan so as to rotate the fan blade in a desired direction. A baffle is affixed to umbrella so as to direct air from the fan along the inner surface of the umbrella. The umbrella has at least one adjustable slat extending outwardly from the inner surface so as to direct air flow from the fan to a desired location below the umbrella. A table is positioned around the tubular support and over the base.

Abstract: A table umbrella apparatus including a tubular support member, a hub rotatably mounted at an end of the tubular support member, a fan extending radially outwardly of the hub so as to be in the form of a table umbrella, and a motor connected to the hub for rotating the fan about a longitudinal axis of the tubular support member. A shaft is connected to the motor and is connected to the hub. The shaft extends longitudinally along an interior of the tubular support member. The shaft is supported by bearings interior of the tubular support member. A base is connected to the bottom of the tubular support member so as to support the tubular support member in a vertical orientation. A table is supported around the tubular support member in a horizontal plane. The fan has a plurality of fan blades. Each fan blade has a wire frame having one end connected to the hub and extending outwardly therefrom and a covering extending over the wire frame.

Abstract: A syringe having a cylinder and a piston longitudinally and rotationably movable in the cylinder. First and second sets of one-way ratchet shoulders and ratchet keys are provided between the cylinder and the piston in which the first set of shoulders and key, when engaged, allow movement of the piston in one longitudinal direction but prevent movement in the opposite second direction. The second set of shoulders and key, when engaged, allow movement of the piston in the second direction but prevent movement in the first direction. A rotational control between the piston and the cylinder provides for sequentially disengaging and engaging the first and second sets of ratchet shoulders and keys upon rotation of the piston relative to the cylinder for operating the syringe for a single cycle.
