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.

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.

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.

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&deg; with the generated wind for a narrow, focused beam, and to 45&deg; 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 &ldquo;burst&rdquo; 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 &ldquo;burst&rdquo; 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.

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.

A system and method for generating tornadoes and other vortex phenomen in an open air, free space enviroment is disclosed. The system includes a flat surface or deck suspended above the ground, a circular hole in the center of the deck, a means for creating an updraft through the hole in the deck and fans or other air moving means for creating a swirling air flow. Preferably, the fans for swirling the air are angled approximately 45 degrees relative to the vertical axis of the updraft flow through the center hole. For swirling the air at higher elevations, as well as at ground level, a multi level fan arrangement having the layers of fans spaced relative to the deck is used. Alternatively, a single level of fans are used in conjunction with louvers or vanes for deflecting the blown air into a fan shape. In another embodiment of the present invention, tangential flow is established by using a multiplicity of tubes for returning air flow from a plenum above an updraft fan. Higher elevation air swirling is accomplished by providing vents in the return columns along the entire length. The vents can be holes in the columns or arrangements of adjustable or fixed vanes. Controls, including valves and shutters, are positioned in the return tubes for adjusting air flow patterns. The present system and method does not require containing chambers to remove external perturbations and to constrain air flow, actively, as opposed to passively, creates the swirling tangential flow, can be operated or performed indoors or outdoors and works with an asymmetric air flow.

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. The nozzle assembly releases an air-oil mist which flows through openings in an end of a U-shaped marble chamber to remove large oil droplets from the mist. The air and oil mist flows outward through a curved outlet, and then flows upward through an opening in the top of the fogger head box. Air flowing from the fan chamber through the air entrainment duct mixes with an entrains the mist and carries it outward through a full rectangular opening at the top of the second end of the case.

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.

Aerosol diffusion fogger

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. Oil collected by the marbles drains through the nozzle chamber into the sump, and the mist continues upward and horizontally through the top filter chamber, which has a foam filter. The mist is exhausted into the mist duct, where it is entrained in the air delivered by the fans which carries the fog to the desired location. The fog head and mist duct are located in a vertically hinged door on the road case.
