Abstract: An apparatus for purifying air which may act as a downstream supplement to a catalytic converter of an internal combustion engine for further reducing the hydrocarbon and carbon monoxide gases which the catalytic converter failed to remove. The apparatus comprises a housing filled with volcanic ash over which is directed a turbulent stream of exhaust gases for chemical reaction with the volcanic ash.
Abstract: A wheel mounted cane secured to extend laterally from a four-wheeled carriage for use in supporting and balancing a user while walking and including an adjustable braking means for the carriage.
Abstract: An improved emulsification base and a method for manufacturing same for non-aqueous chemical additives comprisesa mixture of water from 68 to 92 percent, of 2-amino-2 methyl-1 propanol from 0.1 to 0.2 percent, of an emulsifying surfactant blend from about 2.2 to 3.2 percent, of methyl esters of soybean oil from about 15-20 percent and of a 30% solution of polymer thickener from about 0.25 to 0.50 percent.
Abstract: A mechanism for steering a beam guided vehicle having four steerable wheels linked to a centrally located steering trolley guided by an electrified T-shape beam mounted on a structural roadbed. A trolley flexibly propelled by the vehicle follows the guide beam to actuate the steering of the wheels. The trolley is quickly detachable by drop-pit access for rapid change-out to periodic off vehicle servicing. Two steering arm sensor posts engaging two sockets in the repositioned trolley guarantee interchangeability of standardized repaired units.
Abstract: This invention is directed to a toy football formed in the shape of a prolate spheroid having a tail extending out of one end thereof and having a plurality of fins extending laterally out of said tail for controlling the momentum of the football during flight.
Abstract: A non-reciprocating Stirling-cycle machine which overcomes problems associated with high drive mechanism forces and vibration that seriously hamper reciprocating Stirling-cycle machines. The design employs Wankel rotors instead of the reciprocating pistons used in prior Stirling machines for effecting the compression and expansion cycles. Key innovations are the use of thermodynamic symmetry to allow coupling of the rotating compression and expansion spaces through simple stationary regenerators, and the coordination of thermodynamic and inertial phasing to allow complete balancing with one simple passive counterweight, which is not possible in reciprocating machines. The design can be scaled over a wide range of temperatures and capacities for use as a cryogenic or utilitarian refrigerator or to function as an external heat powered engine.

Abstract: Silencer for gas discharge device employing easily replaceable cartridge utilizing juxtapositioned layers of wire mesh and porous resilient material which dissipate the energy stored in an exhaust system and deflect under pressure of the exhaust gases to provide a self cleaning function and a cylindrical liner mounted within the cartridge comprising the same or larger wire mesh and wire diameter size than used in the cartridge for capturing the large particles of the exhaust gases before they pass through the layers of wire mesh forming the cartridge.
Abstract: A low-cost atomizing nozzle suitable for use with viscous fuels and other liquids in high and low temperature environments. The nozzle structure comprises a cylindrical hollow tube forming a venturi having inlet and outlet ends, a cylindrical hollow barrel and a fuel catheter. The nozzle provides maximum surface contact between the liquid fuel and atomizing air streams.

Abstract: A quick disconnect buckle made of a strong and flexible plastic such as poly carbonate, the buckle intended for personal or industrial use, with a high degree of strength relative to buckle dimensions achieved through the incorporation of a latch that employs a single large latching plate and mating opening that cover approximately half the face of the buckle.
Abstract: A termiticide distribution system for treating an underlying area of a slab wherein a plurality of apertured distribution lines are arranged to offset a plurality of negative pressure and flow gradients of others of said distribution lines to uniformly enhance the coverage of the area treated.
Abstract: A caddy for storage and transportation of a heavy-duty electrical extension cord, the caddy comprising a reel mounted inside a protective container. A cord is wound on the reel for storage and subsequently unwound for use, the tendency for tangling and twisting characteristic of hand-coiled cords is avoided. Storage inside the container protects the cord against damage during transportation.
Abstract: Lugs for detachably mounting on the chain of a conventional tire mounted wheel of a vehicle. The lug being detachably mounted to a portion of the chain which extends laterally over the tread of the tire mounted wheel of a vehicle. The lugs being means for extracting a vehicle from a snow filled ditch or from ice, mud or sand.
Abstract: A ladder support system for use in securely mooring the top of a ladder to a roof while simultaneously eliminating any destructive contact between the ladder and the roof materials. The ladder support system includes a pair of frame portions which are secured to the roof and which are structured to support opposite ends of a bar. To prevent the ladder from rotating away from the roof when being used, a strap is provided for securing the ladder to the bar. Each frame portion is provided with a blocking means to prevent lateral movement of the ladder when the ladder is supported by the bar. A means is also provided to prevent accidental loss of bar support at each frame portion.
