Abstract: A parking space is reserved by raising a chain about three feet above a parking space. The chain is attached to a post, and a weight is attached to the chain to lower the chain along the post and to drag the lowering chain along the parking space toward the post for full access. A motor with a speed reducer turns a shaft with a chain drive gear and an encoder. A signal receiver and control start the motor to raise or lower the chain when one of two buttons is pressed on a key fob by the authorized space user. The encoder is connected to the control to stop the chain when fully up or down. A stop trigger on the chain activates a stop switch when the chain is fully raised.

Abstract: Portable RF radio transceivers, commonly known as walkie talkies, are powered by common replaceable batteries. Mobile devices, including cell phones, are chargeable from the walkie talkies having power output ports. USB or mini USB ports on the walkie talkies are used for the power outputs to charge mobile devices while moving through locations without interrupting both types of the communication devices.

Abstract: A treadmill having a belt assembly allows a user to walk or run in any arbitrary direction. A flattened flexible toroid bladder injected with a lubricant, and stretched over a frame with rotating members. Separate power-driven mechanisms concurrently rotate the toroid belt around the major and minor axis to allow omni-directional user movement.

Abstract: The present invention is a fan with adjustable vanes for controlling the width of the wind generated by the fan. The vanes are adjustable to any angle. Preferably, the vanes are set at 10° with the generated wind for a narrow, focused beam, and to 45° with the generated wind for a diffuse, flood beam. The vanes are adjustable from a dial located on the outside of the fan housing. A motor drives the fan. The motor is controlled by a rotating dial on the outside of the fan housing. The rotating dial allows for adjusting the motor speed from 0 to 100%. Pressing a “burst” button located on the outside of the fan housing instantly provides 100% motor speed. The fan motor runs at full speed for as long as the “burst” button is depressed. A mounting yoke is pivotally connected to opposite sides of the fan housing, allowing the fan to be set at various angles.

Abstract: A fan advertising device has a portable barrel with a fan, a pivotable or tiltable stand and a modified exterior fan housing. Metal fittings on the inside of the barrel, near the output end of the fan, allow for connection of metal inserts for accessories. The sock is held in place by a shock cord that fits into a groove on the exterior of the fan housing near the output end. A circular opening is located below the groove but above the fan to allow various objects, such as ping pong balls, to be placed into the airstream inside the sock. Those objects act as noise makers, attracting attention to and adding to the visual effectiveness of the sock. A light may be attached to the grate on the inside of the fan allowing for illumination of the entire sock. Illuminating the sock is useful for increasing visibility during darker hours.

Abstract: A compact special effects fogger has a small case with a handle on top for ease in transportation. A compressor box is positioned in the case against the base, and against one side and one end of the case. A fogger head box extends across the case on top of the compressor box. The two boxes form within the case a fan chamber at one end, a compressor cooling duct along one side, and an air entrainment duct along the top. A motor drives a compressor within the compressor box. A shaft from the motor extends into the fan chamber. A squirrel cage fan driven by the shaft draws air in through a round opening in the first end of the case and increases pressure in the fan chamber, causing air to flow through the ducts. The fogger head box has an oil sump and an oil intake is mounted in the sump. Oil tubes lead to a nozzle assembly within the fogger head. Compressed air flows through an air cooler in the compressor box and through a water trap in the fan chamber and into the nozzle assembly.

Abstract: An aerosol diffusion fogger apparatus has an aerosol can containing about 10% by weight light white mineral oil and about 90% by weight of an isobutane and propane propellant mixture and having an aerosol valve with a vapor tap and having a fine aerosol nozzle for producing a fine, evenly dispersed and stable fog having particle sizes less than one micron for use in special effects cinematography and still photography.

Abstract: A diffusion fogger is packed on a road case. Fans draw air through a baffle chamber and through fan openings into a fan chamber, an air compressor above the fan chamber provides compressed air to a fog head assembly. The fog head assembly releases an oil mist fog into a fog duct. Air from the fan chamber is blown through the duct and out through a front opening, entraining and delivering the fog. Air from the fan chamber is circulated over a path that serves to cool the compressor, compressed air, and exhausts from the outlet ducts. The fog head is a removable vertical assembly of an oil sump chamber and a nozzle array chamber. The nozzles, with inlets to an air manifold draw up filtered oil from an oil manifold and spray a fine mist of oil and decompressed air into the nozzle chamber. The mist continues through the next above baffle box filled with marbles, removing large oil droplets.
