A homogenous charge compression ignition barrel engine includes an engine housing with a first and second end. An elongated power shaft is longitudinally disposed in the engine housing and defines a longitudinal axis of the engine. A plurality of cylinders surround the longitudinal axis with each cylinder having a closed end and an open end. Each cylinder has a central axis. The open ends of the cylinders are each generally directed toward the first end of the housing. An intake system is operable to introduce a combustible mixture of air and fuel into each of the cylinders. A track is disposed between the first end of the housing and the open ends of the cylinders such that a portion of the track is disposed generally in alignment with the central axis of each of the cylinders. The track has a cam surface that longitudinally undulates with respect to the open ends of the cylinders. A portion of the cam surface is disposed generally in alignment with the central axis of each of the cylinders. The track and the cylinders are rotatable with respect to each other such that the undulating cam surface moves with respect to the open ends of the cylinders. A piston is moveably disposed in each of the cylinders such that a combustion chamber is defined between the piston and the closed end of the cylinder. Each piston is in mechanical communication with the cam surface of the track such that as the cylinders and the track move with respect to each other, the pistons reciprocate within the cylinders. Each cylinder is operable to compress a combustible mixture until the mixture auto ignites, without the introduction of a spark.

This present invention relates to a ratchet wrench and a torque indicator combined concentrically in a single housing. The ratchet wrench is useful for driving a fastener used in dentistry, such as an abutment screw that holds an abutment on a dental implant. In operation, the handle of the wrench can be rotated in one direction (e.g. clockwise) to impart torque on the fastener. When the handle is rotated in the opposite direction (e.g. counterclockwise), no torque is applied to the fastener as the handle is returned to a position where it is easy for the clinician to again rotate the handle to apply additional torque to the fastener. The return motion of the handle (e.g. counterclockwise rotation) may be stepless in operation which is brought about through a coiled clutch spring located in an annular space within a housing between the housing and a concentric driver member. To provide an indication of torque, a rotor body is supported coaxially within the driver member. Torque indicator marks on the rotor body and the driver member indicate angular displacement of the driver member around the common axis relative to the rotor body when a tool held in the rotor body is restrained from turning under load. The housing and with it the drive member may be turned by hand around their common axis when the housing is turned in the latched direction, or a handle fixed to the housing may be used. A lubricating washer is supplied to reduce friction within the ratchet wrench.

In accordance with the present invention, there is provided an aerodynamic control device for integrated use with an aircraft having an inboard lifting member. The inboard lifting member having a leading edge, a pair of opposing distal edges and a trailing edge. The control device is provided with a movable outboard member which extends substantially about the leading, distal and trailing edges of the inboard lifting member and is spaced apart therefrom. The outboard member is provided with a leading edge portion, a pair of opposing distal edge portions, and a trailing edge portion. The leading, distal, and trailing edge portions are movable in relation to the inboard lifting member to form an airfoil surface extending about the inboard lifting member and the outboard member for achieving aerodynamic control of the aircraft. The trailing edge portion has at least one deflectable segment which is vertically movable in relation to the leading and distal edge portions for achieving further aerodynamic control of the aircraft.

A rotary wing aircraft is provided with longitudinally oriented counter-rotating rotors with circumferentially spaced variable pitch elongated rotor blades connected at their opposite ends to rotatable support rings mounted on the aircraft fuselage. Rotor downwash may be guided laterally and longitudinally by respective sets of moveable guide vanes. Propulsion may be obtained by an engine providing thrust and power take-off for driving the rotors. An auxiliary or second engine may be drivingly connected to the rotors.

An internal combustion four cycle engine is provided with a plurality of stationarily mounted cylinders radially arranged in equal spaced apart relationship within the inner circumference of a rotatably mounted drive drum and in parallel relationship with the axis of rotation thereof, a movable track anchorably supported by a pair of oppositely disposed raised lobes fixed to the interior webbed surface of the drum and comprised of two pairs of declining slope track quadrants serving to receive the driving thrust of each piston during its power stroke and to activate each piston during its intake, compression and exhaust strokes, and a cam ring fixed to the inner circumference of the drive drum serving to activate an intake-exhaust slide of each cylinder commensurate with the requirements of its intake, compression, power and exhaust strokes. Means resiliently coupled to a hollow exterior hub of the drum and extending internally thereof into rotatable relationship with the webbed surface serves as output means for the engine and to variably elevate the declining slope track quadrants according to the torque load that is applied to the output means, whereby the pistons of the cylinders are provided with a constant power stroke and a variable intake stroke and whereby the intake stroke attains a predetermined maximum length in the presence of a torque load applied to the output means and a predetermined minimum length in the absence of a torque load.

In a machine such as a motorcycle wherein a two cycle gasoline engine is drivably coupled to a rotatable output member by a pair of chain connected sprockets, and wherein the drive chain connecting the sprockets requires regular and periodic lubrication to assure optimized efficiency in operation and prolonged life of the chain, an emissions collector is provided in association with the exhaust pipe of the engine to collect a portion of the combustion emissions generated thereby, such collected emissions being directed by a diverter to the drive chain such that the residual of oil forming a part of the emissions is applied continuously to the chain during operation of the machine to thereby maintain a protective, wear-preventing coating of lubricant thereon.

A torque measuring device designed for convenient use intermediate a ratchet wrench and socket is provided with a pair of oppositely disposed compression springs that are so housed within the first of a pair of complementary plates as to yield to a rotational force applied in either direction, the compressible yield of one of the springs as the ratchet wrench is turned in a given direction producing a lag in the rotation of the second of the plates which is measured in terms of torque by means of a pointer and a calibrated scale, the convenient substitution of the springs with selected springs of varying tension permitting the wide range of torque measurement including measurement in foot pounds, inch pounds, and metric.

An aircraft comprised of a pair of spaced apart interconnected air-frame members and a cargo compartment supported therewithin is provided with a plurality of expansible airfoils mounted for peripheral movement around the air-frame members as driven by a motor and associated drive, movement of the airfoils along the frontmost perimeters of the air-frame members providing the aircraft with forward thrust, and movement thereof along the uppermost perimeters of the air-frame members accentuating the lift provided by the airfoils. Structure associated with the motor and drive and with the mounting of the airfoils for peripheral movement around the air-frame members serves to controllably and elevationally alter the plano-convex profiles of the airfoils as they are driven along the uppermost and frontmost perimeters and to thus vary the lift and forward thrust provided respectively thereby, optimum elevational expansion of the airfoils as they are driven along the uppermost perimeters of the air-frame members serving to maximize the lift of the aircraft, and optimum elevational expansion thereof as they are driven along the frontmost perimeters serving to maximize the forward thrust of the aircraft.
