Abstract: The present invention is for an automatically actuated hidden compartment apparatus and method for creating the illusion that an object placed inside a chamber has disappeared. An automatically actuated hidden compartment apparatus comprises a housing, an outer compartment slidably coupled to the housing, an inner chamber slidably coupled to the inside of the outer compartment, and actuating means within the housing. When the inner chamber and outer compartment are slidably opened, an object is placed in the inner chamber. When the inner chamber and the outer compartment is closed, the actuating means is triggered, thereby preventing the inner chamber from sliding out of the housing. Then, when the outer compartment is opened an illusion is created that the object has disappeared. When the outer compartment is closed, the actuating means is triggered, thereby allowing the inner chamber to slide open. Then when the inner chamber and outer compartment is opened, the object reappears completing the illusion.

Abstract: A system for metering and dispensing single and plural component liquids and solids as described herein. The dispensing system has a microprocessor-based control system and progressive cavity pumps which provide a very accurate control of component ratios, shot sizes, flow rates and dispense durations. The system has numerous feedback components for accurately controlling the pressure, flow rates, fluid levels and amounts of fluids dispensed. Where a valved nozzle is used, the pressure in the flow system is used to control the pumps rather than the valve. Such a system may be used as a sprayer with compressed air added. Drum rams are associated with the supply drums and the progressive cavity pumps may be placed on the drum ram. Maintenance of a steady state in the system is accomplished with back and forth movement of the pump, with compensation for pressure changes. Absolute rotational position of the pump can be monitored when a set pressure is maintained, to diagnose system conditions.

Abstract: The present invention is an aerodynamic wind riding antenna ornament comprising a main body adapted to be rotatably and slidably attached to an antenna mast. The main body has an aerodynamic lifting surface to harness airflow from the movement of a vehicle to move the ornament up and down the antenna mast. The main body also has an aperture of sufficient size to allow for the device to freely slide up and down an antenna mast. Retaining means is removably coupled to the aerodynamic lifting surface near the aperture to prevent the aerodynamic wind riding antenna ornament from sliding off the top of the antenna. The retaining means can comprise a snap-on clip, spring-like clip, or a portion of an ornamental figure removably coupled to the main body. Optional stopper clamps can be removably coupled to the antenna to restrict where the device travels on the antenna. The device can have optically perceived indicia to increase the appearance.
