Abstract: An improved refrigeration system that has an air cooled condenser exposed to outdoor ambient conditions and which automatically maintains sufficient head pressure during cooler weather for adequate liquid flow to the expansion valve of the evaporator by backflooding the condenser. Sub-cooling of the liquid in the condenser results from the backflooding and this sub-cooled liquid flows into the liquid line to the expansion valve. The liquid line out of the receiver joins the liquid line below the receiver so that the pressure in the receiver can be used to maintain the liquid level and the presence of liquid at the condenser. Means is provided to control the refrigerant pressure in the receiver in response to liquid level in the outlet line from the condenser.

Abstract: The present invention is a furnace for burning pelletized or particulate fuel. The furnace has a split auger located within a serpentine fuel conduit which controllably feeds pelletized fuel into a contained burner, wherein the fuel is exposed to fire and a forced air plenum. The fuel is contained within the burner and exposed to high temperatures until the fuel is sufficiently burnt to pass through apertures in a perforated baffle. Further combustion is achieved by passing the heated combustible gases through multiple combustion chambers. A heat exchanger passes air by the multiple combustion chambers, thereby collecting the produced heat, and distributes the heated air into residential or commercial air circulation systems.

Abstract: The present invention is a test valve plug assembly designed to be installed within a drain tee which connects a tub drainage and overflow system to the drainage system of a building. In its closed position, the test valve plug provides a means for closing the drain tee, thereby permitting the drainage system below the drain tee to be filled with water for testing purposes.

Abstract: A multi-channel pipe for monitoring groundwater in aquifers at multiple levels below a single site. Pipe sections each comprise an outer wall, an interior element dividing the pipe into multiple channels, a monitoring port opening into one of the channels, coupling means for joining pipe sections lengthwise to each other, and a plug for plugging the channel immediately below the monitoring ports. The interior element is preferably star-shaped, having a hollow cylindrical central core and eight radial segments affixed between the core and the outer wall. Each channel is defined in part by the outer wall and in part by two adjacent segments of the interior element. Corresponding channels of adjacent pipe sections are joined by couplings each channel receiving one end of a coupling. A capped plug is inserted into the upper end of the coupling below immediately above the monitoring ports of a channel. An inflatable packer encircling the pipe seals the drill hole between groups of monitoring ports.

Abstract: The double deadrise with multiple reflex chine boat hull structure and engine mounting system relate to designs for power boat hull structures and engine mounting systems. The hull structure combines the use of two pairs of bottom surfaces, reflex chines and side panels to form a double deadrise hull structure. This design imparts a highly efficient means for dynamic tracking, thereby, preventing "slide-out". The design also enables the hull structure to quickly and easily achieve a plane. The engine mounting device provides an improved means for securing and supporting an engine to a hull structure. The engine mounting device permits the hull structure to have a high transom, reduces the space in the working compartment that would otherwise be occupied by the engine, engine housing, or engine well, permits the proper positioning of the propeller within the water reservoir to achieve optimum thrust performance, provides static flotation and incorporates all of the benefits achieved in the new hull design.

Abstract: An improved refrigeration system that has an air cooled condenser exposed to outdoor ambient conditions and which automatically maintains sufficient head pressure during cooler weather for adequate liquid flow to the expansion valve of the evaporator by backflooding the condenser. Sub-cooling of the liquid in the condenser results from the backflooding and this sub-cooled liquid is diverted through a bypass line around the receiver to a sub-receiver and thereby to the liquid line to the expansion valve. In warmer weather, the liquid or a liquid and gaseous mixture from the condenser can enter the receiver or the bypass line. The liquid line out of the receiver forms a drop leg and joins the bypass line at the sub-receiver at a sufficient elevation below the receiver so that the pressure due to the static head at the sub-receiver is greater than the pressure at the receiver, said pressure difference causing any gaseous and liquid mixture from the condenser to flow to the receiver.

Abstract: A self-governing, vertically oriented wind driven assembly is provided by a pair of open, semicylindrically shaped wind scoops with elongated edges which face each other in a nearly closed position at times of high or maximum wind speeds, and partically face each other and partially exposed into the wind at lower wind speeds. The scoops are pivotally attached to posts oppositely located at the edges of a rotating frame. The amount of exposure of the scoops into the wind is dynamically balanced by springs which tend to open the scoops and by weights which tend to close the scoops proportional to the rotational speed of the assembly. The ends of the scoops are modified to permit the scoops to cooperatively slide from an open to close position. The assembly is connected to an electrical generating means and can be used for producing electrical power on sailboats.

Abstract: A utility garment for load portage in the shape of a vest containing load carrying compartments on the back and front flaps of the vest. The vest closes at the front, and a waist belt attached to back and front flaps through tie down loops holds the loaded vest to the wearer to prevent shifting of loads and upward creeping of the front flaps and to distribute a portion of the read load directly to the wearer's hip region. A stowable water repellent seat protector hangs from the bottom of the back of the pack for the packer to sit upon.
