Abstract: There is disclosed herein an impeller for a centrifugal pump such as water pumps for automotive internal combustion engines or a centrifugal pump for liquids other than water. The impeller has a circular base and a series of similar vanes extending vertically from the base. Each vane extends rearwardly from its inner end to its outer end with respect to the direction of rotation of the rotor and is wider at its midpoint than its ends. The leading edge of each vane is concave at least at its inner end while the trailing edge of each vane is convex.

Abstract: A glass lined container such as a vessel or conduit for liquid or gaseous material is disclosed consisting of a strong outer shell and an inner glass liner.

Abstract: The present invention provides improved multiple stage reed valve construction for internal combustion engines. The reed valves comprise first stage reed valves with multiple ports in the first stage reed valve. Beams having a smoothly shaped curve from the base of the first stage reed valve to the apex thereof and narrowing toward the apex separate adjacent ports. The reed valves of the present invention provide significant improvements in engine operation.

Abstract: The present invention provides improved multiple stage reed valve construction for internal combustion engines. The reed valves comprise first stage reed valves with enlarged ports, enlarged second stage reed valves corresponding with the ports, and one or more webs positioned in the ports to help support the second stage reed member when it is in a closed position. The reed valves of the present invention provide significant improvements in engine operation and tremendous increase in reed valve operational life.

Abstract: A rotary exhaust control valve for two-stroke cycle engines is disclosed. This valve is oriented at least partially within the exhaust passage and, for each revolution of the engine, delays flow from the combustion chamber through the exhaust passage during the expansion stroke of the piston while permitting full opening of the exhaust passage and blow down to initiate the scavenging cycle of the engine. The valve of the present invention permits complete opening and closing of the exhaust passage during the appropriate portions of the engine cycle. Also disclosed is a mechanical linkage mechanism between the rotary valve and the crankshaft to provide precise control of the exhaust valve throughout the engine cycle.

Abstract: A sliding exhaust control valve for two-stroke cycle engines is disclosed. This valve actuates at least partially through the exhaust passage and delays flow from the combustion chamber through the exhaust passage during the expansion stroke of the piston while permitting full opening of the exhaust passage and giving complete blow down before the scavenging cycle of the engine. Also disclosed is a mechanical linkage mechanism between the slide valve and the crankshaft and cam controlled actuation means to provide precise control of the exhaust valve throughout the engine cycle.

Abstract: An exhaust control valve for two-stroke cycle engines used in conjunction with a fuel injection system is disclosed. This valve is within the exhaust passage and, for each revolution of the engine, delays opening of the exhaust passage to the combustion chamber during the expansion stroke of the piston for a preselected number of degrees of rotation of the crankshaft while permitting the necessary opening of the exhaust port to give complete blow down before the scavenging cycle. The valve also permits advanced closing of the exhaust port to eliminate short circuiting of the fresh charge out the exhaust port. A fuel injection system, providing fuel either upstream or downstream from valves in the engine's air intake passage, is provided to operate in timed relation to the piston strokes and the exhaust valve. Also disclosed are means for modifying opening of the exhaust valve at high engine speeds to improve scavenging.

Abstract: Reed valve mechanism for use in the fuel/air supply system of an internal combustion engine, the mechanism including passages, ports and reed valves, all of which are arranged to minimize unnecessary fluctuations of the flow velocity of the fuel/air being delivered to and into the cylinder of an engine and also minimize localized turbulence in the flow path and thereby increase the power output of the engine.

Abstract: A chair, particularly adapted for use by infants, is disclosed, including a chair body having a generally upright part with a forwardly inclined supporting surface and an interconnected rearwardly extending lower part adapted to form a seat for the infant when the infant is positioned on the chair with the front of the torso presented toward the upright end forwardly inclined chair body, the chair further including adjustable infant supporting means mounted on the chair body and having upper and lower portions presented at an upwardly and rearwardly inclined angle, thereby providing for gravitational support of upper and lower portions of an infant occupant in a forwardly inclined position.

Abstract: An exhaust control valve for two-stroke cycle engines is disclosed. This valve is within the exhaust passage, seals against the piston, and delays opening of the exhaust passage to the combustion chamber during the expansion stroke of the piston for a preselected number of degrees of rotation of the crankshaft while permitting full opening of the exhaust port during the scavenging cycle. Also disclosed are means for modifying opening of the exhaust valve at high engine speeds to improve scavenging.

Abstract: Reed valves for internal combustion engines are disclosed, the reed valves having protective coating of synthetic rubber.

Abstract: A suspension system for the drive wheel of a motorcycle driven by a chain cooperating with sprockets on the engine and wheel shafts. The suspension system comprises a linkage arrangement associated with the swing arm, with the linkage parts positioned in the region between the wheel and the motor, with the swing arm substantially in a plane containing the axes of the engine and wheel sprockets, and with linkage components defining or approximating a parallelogram configuration.
