Abstract: A fuel supply system for internal combustion engines whereby a liquid hydrocarbon fuel is supplied to an enclosed pressure chamber, and wherein the chamber the liquid fuel is heated to within temperature limit of 95% plus or minus 5% of that said fuel's refined distillation end point. At that temperature high vapor pressure exists within the enclosed compression chamber. The resulting vapor is conveyed to the carburetor venturi system and combustion chamber in true vaporous state by means through a cooperating system of primary and secondary pressure reducing regulators. Attached onto the interior wall of the compression chamber is a liquid fuel dispensing pump, which maintains a constant fuel level within that chamber. Energy to operate the pump is derived from surrounding pressure within the compression chamber.

Abstract: The anode of an arc lamp is supported on an arm. When the arc lamp fails, motion of the arm detects the failure and turns the current off of the arc lamp. In addition, after failure of the lamp, the arm limits motion of the anode so that it does not strike adjacent structure.

Abstract: The invention relates to an oil separator for blowby gas having a baffle with a side wall and a bottom wall. A cut piece is bent from the bottom wall. A shut-off member is attached to the side wall and has a first wall located at a spaced distance from and opposed to the bottom end of the cut piece. The bottom end of the first wall is located between a first line extending from the bottom end of the cut piece and perpendicular to the first wall, and an intersection point defined at the intersection of an extension of the cut piece and an extension of the first wall. According to the inventive structure, the oil drops splashed by the rotating cam and reflected from a side wall of a cylinder head cover toward the baffle are effectively prevented from entering the baffle.

Abstract: An improved diesel fuel heater wherein a predetermined quantity of fuel is captured within the heater in a reservoir defined therein. This quantity is heated by the heater's positive temperature coefficient (PTC) thermistors (and heat conductive mounting plate) to assure a heated quantity of fuel will be pumped into the fuel system's filter element to enhance de-waxing thereof.

Abstract: A heat exchanger system for internal combustion engines, both spark (gas) and or self-ignition (diesel) and liquid or air-cooled engines in which a duct or enclosure, fabricated entirely of non-heat conducting materials, which completely surrounds the rear of existing heat exchanger, cooling coil, or cooling fins, removes excessive heat by ducted air being routed through disposable air-filter, then into the velocity accelerator section, from there into the plenum or accumulater section to be consumed by the engine. The improvement being that no excessive heat is allowed to accumulate or be discharged into the engine compartment, fan and pulley arrangement are eliminated, reducing noise and excessive power loss, filtered air is accelerated to super-sonic velocities to better atomize fuel, allowing for greater volumetric efficiency of cylinders, all work being performed by the pressure differentials produced within the engines cylinders during its intake cycles or strokes.

Abstract: A fuel mixture injection apparatus associated with the carburetor of an internal combustion engine designed to improve engine efficiency by delivering a mixture of vaporized gasoline, steam and air directly to the carburetor. A portion of the fuel supplied by the fuel pump is diverted through a metering valve into a closed chamber where it is sprayed over a perforated vaporizer grid heated by a double loop of copper tubing through which hot engine coolant is ducted. The gasoline vapor is then ducted either into the carburetor or directly into the intake manifold. Simultaneously, water from a reservoir flows through a line in response to engine load and temperature conditions. The line passes through the closed chamber where the water is preheated. The line then leads to a heat exchanger connected to the engine's exhaust manifold where the water is converted to steam. From the heat exchanger, the steam is ducted either into the carburetor or directly into the intake manifold.

The coolant distributor passage and collector passages both extend along the cylinder row, one on one side of the cylinder row and the other on the opposite side. The distributor passage is formed in an upper portion of the cylinder block near the cylinder head. The collector passage is formed in the cylinder head. One longitudinal end of the collector passage is connected to the pump.

Abstract: A conveyor system in which loads supported by forwardly driven carriers of an overhead power and free conveyor are automatically transferred to a second conveyor arranged below the overhead conveyor at a transfer zone and driven at the same forward speed. The vertical spacing between the overhead and second conveyors is decreased from a greater spacing at which a load is engaged and supported by downwardly extending structure of a carrier to a lesser spacing at which the load is disengaged from the carrier structure and is supported by the second conveyor. As the disengaged carrier and load move forwardly in unison on their respective overhead and second conveyors, the carrier is engaged and moved by a transfer conveyor obliquely to the second conveyor at an increased speed such that the carrier continues to move forwardly in unison with the load while simultaneously moving laterally out of alignment therewith.

Abstract: The invention comprises a carburetion apparatus for use with an internal combustion engine having a generally conventional carburetor, an intake manifold and an exhaust manifold. The carburetion apparatus has a central chamber that receives the fuel-air mixture from the carburetor and delivers the fuel-air mixture to the intake manifold. The central chamber is provided with baffles to divert the fluid flow and cause intimate mixing of fuel and air. The baffles are such that the manifold vacuum is raised (or, the pressure is lowered), so the vacuum assists in evaporating liquid fuel. The baffles may be heated by passing exhaust gases through them, the exit of the exhaust gas being slowed by a constricted outlet.

Abstract: A fuel preheater and emission control device for heating fuel being supplied through a fuel conduit from a fuel supply to the engine, and thereby improving its combustion. Fuel heating is accomplished as a result of heat exchange between the fuel and engine coolant flowing in a coolant conduit. The preheater comprises a coolant tube adapted to have heated coolant flow therethrough and a fuel tube adapted to have fuel flow therethrough enroute to the engine. The fuel tube includes a coil having a plurality of convolutions extending around the exterior of the coolant tube and a downstream section extending for a substantial distance within the coolant tube. The region of the downstream section between the most downstream convolution and the location at which the downstream section enters the coolant tube is spaced from the coolant tube in a way to minimize the likelihood of vapor lock, while the downstream section assures adequate fast heating for improved cold-weather performance and emission control.
