Abstract: A system for sealing an air duct by coating the interior of the duct with a material similar to the coating used for spray-on truck bed liners. A spray device applies the liner material to the interior surface of the ducts and the spray device is held in the center of the duct by retractable sets of wheels. The spray device is removably attached to a supply hose that provides liner material to the spray device from a storage tank via a supply pump. The supply hose is first fed through the duct, the spray head is attached to the supply hose and the liner material is sprayed onto the duct as the spray head is retracted through the duct. The system can be either computer or manually controlled and can optionally employ an electrostatic unit to put opposite electrical charges on the duct and the liner material.

Abstract: An automatically adjusting jet mixer used in mixing fracturing fluid gel for gas and oil wells. The mixer has an inner nozzle and an attached piston that move axially within the mixer's housing to change the size of the nozzle opening thorough which mix water enters the mixer. One side of the piston has a pressure regulated area and an opposite side has an upstream area. The upstream area is connected to the mix water supply pump and the pressure regulated area is connected to the outlet of a pressure regulator that maintains a constant pressure in the pressure regulated area. The piston and the nozzle move via hydraulic pressure exerted on the piston in proportion to the change in pressure in the upstream area to a position that will maintain a constant mixing jet pressure, thus providing constant specific mixing energy, i.e. constant energy per unit mass of fluid.

Abstract: A device for automatically collecting loose pet hair, debris and allergens from a pet as the pet enters or leaves the device where the pet is fed, thus keeping the pet owner's house cleaner. The device is a container consisting of three interconnected compartments. Loose particles are removed from the pet by air suction as the pet passes through collector plate assemblies in the first compartment to reach its food in the second compartment. A fan that induces the air suction in the first compartment and the filter that removes the hair from the air stream are both located in the third compartment. A sensor in the second compartment signals a receiver associated with the fan to turn the fan on and off based on the presence of an animal within the device. An optional second exit with a one way door can be provided in the second compartment.

Abstract: A metering valve for metering dry powder material such as cement. The interior of the valve housing is expanded outward beginning at the sealing surface or lip located adjacent to the inlet opening, thereby forming an enlarged gap between the valve sleeve and housing to discourage powder accumulation in the gap and interference of large bulk particles and foreign materials with the sleeve and housing. An eccentric intermediate sleeve aligns the valve sleeve relative to the housing prior to rotation of the valve sleeve by either moving the valve sleeve away from or toward the valve inlet. The valve sleeve has a rubberized layer to seal with the housing's sealing surface or lip. A sleeve shield blocks entry of powder into the mouths of the vacuum breakers to prevent plugging of the vacuum breakers. Ball bearings are employed to suspend the valve sleeve within the housing, making the valve sleeve easier to rotate.

Abstract: An electrically operated, self contained device that eliminates mosquitos by attracting the mosquitos to lay their eggs in trays of water provided in the device and periodically filtering the eggs from the water. The eggs that have been filtered out of the water are then mechanically destroyed by crushing them. The filtered water is recycled to a water supply tank for reuse in refilling the trays of water in the device.

Abstract: A computer controlled positioning table for use in automatically rotating a large diameter article into which an evenly spaced circle of bolt holes are to be drilled. The article to be drilled is centered and clamped onto a table top of the table and then the computer rotates the table top incrementally to precisely position the article relative to an associated stationary drill stand that is used to drill the desired holes in the article. Rotation of the table top is computer controlled, allowing the operator to select the number of bolt holes for each article. Once the table top has rotated to the proper position, locking mechanisms and support roller provided under the table top hold the table top stationary in the proper position while a hole is drilled in the article.

Abstract: A vehicle ramp system for elevating a vehicle off the ground. Tires on one end of a vehicle are driven onto a first set of modified ramps. Each of the modified ramps has an extended elevated horizontal platform and the vehicle's tires are rolled to the terminal end of the elevated platform of the first set of ramps. A second set of ramps is then placed on the opposite side of a second set of tires that are provided on the opposite end of the same vehicle. The vehicle is then reversed in direction so that the second set of tires rolls up onto the second set of ramps until the second set of tires rest on elevated platforms provided on the second set of ramps and the first set of tires are retained on the platform of the first set of ramps.

Abstract: A cable guide for creating an organized cable bundle. A plurality of channels for receiving cable are provided in a rotating column ring at one end of the cable guide and a cylindrical portion terminates at a flexible boot on the opposite end. A slot in the cable guide extends between the two ends of the guide and can be aligned with the individual channels by rotating the column ring to provide access to the channels to add or remove cable therefrom. Each channel is labeled so that the installer can identify its associated cable. Cable ties that are pre-tied around the cylindrical portion can be slid off the cable guide and around the cable bundle. An alternate embodiment of the invention is provided with a second rotatable ring that effectively separates each channel in two separate compartments for receiving twice as many cables.
