The present invention relates to mechanical-electrical power conversion systems. The systems comprise one or more electroactive polymers that convert between electrical and mechanical energy. When a voltage is applied to electrodes contacting an electroactive polymer, the polymer deflects. This deflection may be converted into rotation of a power shaft included in a motor. Repeated deflection of the polymer may then produce continuous rotation of the power shaft.

A multi-axial rod connector for connecting spinal rods is provided. The rod connector includes a poly-axial rod assembly configured to include a lateral translation mechanism and a fixed hook configured to be rigidly coupled to one end of the poly-axial rod assembly. The fixed hook includes a fixed hook cavity configured to secure a spinal rod. The rod connector also includes a variable hook configured to be rotatably coupled another end of the poly-axial rod. The variable hook includes a variable hook cavity configured to secure another spinal rod. The lateral translation mechanism is configured to change distance between the fixed hook and the variable hook.

A tightening device adapted to equip an article of footwear, which makes it possible to hold the foot laterally, while distributing on the foot the pressure generated by the tightening device. The tightening device includes an upper flap that partially covers a lower flap. The flaps hold the foot by the tightening device which includes at least one anchor positioned on each of the flaps. The upper flap is more flexible than the lower flap.

A control valve for a device for changing the control times of an internal combustion engine, having a substantially hollow-cylindrical valve housing, a control piston which is arranged within the valve housing and can be displaced axially, a pressure medium connection, two operating connections, and at least one tank connection. The operating connections, the pressure medium connection and the tank connection are formed as radial connections. It is possible for the operating connections to be connected to the pressure medium connection and the tank connection by axial displacement of the control piston within the valve housing. The operating connections are arranged adjacently.

A door assembly has a first door integrated with a second door. The first door has a first door cowl. The second door is pivotably mounted to the first door and has a second door cowl forming at least a portion of the first door cowl. The door assembly includes at least one actuator coupled to the first and second doors. Each one of the first and second doors is pivotable between open and closed positions and defines an opening when moved to the open position. The openings of the first and second doors face in opposite directions. The actuator is operative to pivotably move at least one of the first and second doors between the open and closed positions.

A method of manufacturing a composite laminate and a composite laminate manufactured according to the method are provided. The laminate comprises a series of fabric plies (1 to 15) of fibrous reinforcing material set in plastics matrix material. The method includes the steps of providing a relatively small number of fabric styles from which to choose; selecting at least one of those fabric styles according to design requirements for a particular portion of the laminate; laying up that portion with the said selection, and repeating the selection and layup steps as required to complete the layup of the laminate.

The present invention relates to a rubber crawler including: a joint formed by joining together opposite ends of a crawler body comprising an elastic member shaped like a belt having the opposite ends; and lugs projected at predetermined space intervals along a longitudinal direction of the belt and arranged on an outer circumferential surface of the crawler body. The joint is disposed on the outer circumferential surface of the crawler body, as located in a ground non-engaging portion and at different positions with respect to the longitudinal direction of the belt, the ground non-engaging portion defining an area excluding the lugs. In this way, stress acting on the joint is distributed or reduced.

The invention provides an automobile and a reinforcing device for an inner plate of a rear wheel casing of the automobile, and relates to white bodies of automobiles. The reinforcing device for the inner plate of the rear wheel casing of the automobile is characterized in that an inner plate of a C column is connected to the upper portion of the reinforcing device, a crossbeam of a rear seat and a rear crossbeam of a rear floor are connected to the lower portion of the reinforcing device, the reinforcing device is supported on the inner plate of the rear wheel casing, the reinforcing device for the inner plate of the rear wheel casing of the automobile comprises a support plate for the inner plate of the rear wheel casing and a double-arm reinforcing plate for the inner plate of the rear wheel casing, and the support plate for the inner plate of the rear wheel casing is connected with the inner plate of the C column and is supported on the inner plate of the rear wheel casing; the double-arm reinforcing plate for the inner plate of the rear wheel casing is connected with the support plate for the inner plate of the rear wheel casing and is provided with a front reinforcing arm and a rear reinforcing arm, the front reinforcing arm and the rear reinforcing arm are supported on the inner plate of the rear wheel casing, the front reinforcing arm is further connected onto the crossbeam of the rear seat, and the rear reinforcing arm is further connected onto the rear crossbeam of the rear floor. The automobile and the reinforcing device have the advantages that the Y-direction dynamic and static stiffness of the automobile and the stiffness of a C ring of a body of the automobile can be improved, and the reinforcing device is applicable to manufacturing the white body of the automobile.

A vacuum valve comprises a valve body with a valve opening, a valve plate which is adjustable from an open position, in which it releases the valve opening, to an intermediate position, in which it covers the valve opening but is lifted from the valve seat, into a closed position in which it contacts the valve seat, and from the closed position to the intermediate position into the open position, a valve rod carrying the valve plate, a transverse drive unit by which the valve plate can be displaced in a transverse adjusting direction extending transverse to the longitudinal axis of the valve opening, a longitudinal drive unit by which the valve plate can be displaced in a longitudinal adjusting direction extending parallel to the longitudinal axis of the valve opening and opposite the longitudinal adjusting direction, and a guide device by which the transverse drive unit is guided so as to be displaceable relative to the valve body parallel to the longitudinal adjusting direction. The transverse drive unit is displaced relative to the valve body parallel to the longitudinal adjusting direction when the valve plate is adjusted from its intermediate position to its closed position and from its closed position to its intermediate position.

A series of gear motors, a gear motor, and a planetary-gear stage includes planet wheels that mesh with a sun wheel and inner gear teeth provided for the gear housing. The planet wheels are supported in a rotatable planet carrier, which forms the power take-off, and to which a sealing element is assigned on the output side. The planetary-gear stage is assigned a further sealing element on the input side. The gear housing is shaped on the input side such that an interface is formed for connection to further components, which include at least one shaft connected to the sun wheel.

A level difference portion is formed on a food outer panel of a hood along a longitudinal direction of a vehicle body. A flange that connects a bone portion and a bone portion of a food inner panel is formed at a portion below the level difference portion of the hood outer panel. The flange of the hood inner panel extends so as to be curved along the level difference portion of the hood outer panel. The flange of the hood inner panel is connected to the level difference portion of the hood outer panel using an adhesive agent.
