Abstract: The two-stroke engine has a plurality of intake passages extending from the external air inlet port through the crankcase, separating the intake air charge from the air and oil vapor within the crankcase. The piston has one or more corresponding inlet tubes depending therefrom that telescope within the crankcase intake passages as the piston reciprocates. All intake air travels through these passages and is separated from the remainder of the crankcase volume. The incoming air charge passes through a concentric poppet valve in the piston crown to enter the combustion chamber. Fuel is provided by conventional direct or port injection and ignition is provided by one or more conventional spark plugs. Diesel operation is achievable when the engine is configured appropriately. Exhaust exits the combustion chamber through a poppet valve in the cylinder head, the poppet valve being actuated by a rocker arm and pushrod from a crankshaft driven cam.

Abstract: A variable mechanical valve train for actuating a valve in an internal combustion engine includes a two-part follower operatively coupled between a cam shaft and a valve, so that the follower: in a fully-activated mode, causes a maximum lift of the valve in response to a rotation of the cam shaft; in a partial load mode, collapses partially so as to cause a partial valve lift during the rotation of the cam shaft; and in a deactivated mode, collapses in response to the rotation of the cam resulting in no valve lift.

Abstract: A two-stroke internal combustion engine having a seal assembly disposed between a piston and a running surface. The seal both lubricates and prevents exhaust of combustion gases. A first element, which ensures gas tightness, is received in a countersunk portion of the running surface. A second element, which ensures oil tightness, is partially embedded into the first element. A biasing element presses the second element against the first element so that the second and third elements are at least partially held within the first element.

Abstract: Embodiments of the present invention include methods and apparatus for the detection of objects using acoustic imaging. Vibrational resonance characteristics of man-made objects may be significantly different from those of the surrounding natural materials, allowing an acoustic image to highlight the position of the object, even if the object is concealed from visual imaging.

Abstract: A rotary gasoline engine has two sets of pistons, which move reciprocally. The reciprocal output of said pistons is coupled to an undulating ramp, which converts the reciprocal motion to rotary motion. The engine casing has a hollow center though which no shaft runs. Dual rotary outputs are provided, one through a rotatable output block at the top end of the casing, the other through a rotatable block at the bottom end of the casing in response to the reciprocal motion of the pistons.

Abstract: There is provided a method for generating power from a working fluid wherein the working fluid is a saturated vapor or is superheated to a vapor and then passed to a high pressure zone where the working fluid is used to impart work to a working shaft by means of directly linked high and low pressure cylinder piston assemblies located in the high pressure zone and a low pressure zone, respectively.

Abstract: The present invention pertains to an emergency propulsion system for both motor powered and sailing vessels which have a single propeller shaft. This emergency system may be used with inboard engines or with a sailing vessel that has a small engine used for moving said vessel and/or docking. While and when under way engine failure may be experienced. Such failure is usually very inconvenient to the user of the boat. Many times such failure can and does become a serious matter. The present hydraulic propulsion system of this invention is intended to provide a "get home" drive for trawlers or sailing vessels using a single engine. A small diesel engine that is used to provide electrical generation is also selectively employed to turn a hydrostatic pump and then through a fluid connected means drives a hydrostatic motor which drives a V-belt to the propeller shaft.
