Abstract: An assembly includes at least one piston, a rotating member, a transition arm, and a mechanism. The transition arm is configured to translate between rotational movement of the rotating member and a first linear motion of the piston. The mechanism is configured to superimpose a second linear motion of the piston onto the first linear motion of the piston. The assembly can be a hydraulic (or air) pump or hydraulic (or air) motor, with the second linear motion resulting in reduced output ripple or smooth torque vs. angular rotation, respectively. Also, the assembly can be an alternator or electric motor, with the additional linear motion resulting in an ac waveform that conforms substantially to a sinewave or a back emf that conforms to the input voltage or electric waveform. In addition, the assembly can be an internal combustion engine in which the second linear motion results in the pistons lingering about top dead center during the combustion process.

Abstract: A joint for positioning between first and second elements includes an outer member and an inner member. The first and second elements are arranged for linear motion along a common axis. The outer member is configured for movement relative to the first and second elements along a first axis perpendicular to the common axis, and the inner member is mounted within the outer member for rotation relative to the outer member about a second axis perpendicular to the first axis and the common axis and for movement relative to the outer member along the second axis. The outer member is restrained from movement along the second axis. The outer member defines first and second parallel flat sides. Each flat side defines a plane perpendicular to the common axis. The outer and inner members each defining an opening for receiving a drive arm.

Abstract: In general, an assembly includes at least one piston housed in a cylinder and a transition arm coupled to the piston. The transition arm is coupled to a member that is housed in a channel defined by a rotating member. Movement of the transition arm adjusts a clearance distance between an end face of the piston and an end wall of the cylinder, and causes the member to slide in the channel such that a stroke of the piston is changed. The member is configured to allow the rotating member to rotate relative to the transition arm and/or configured to allow a change in orientation of the transition arm with respect to the rotating member. In other implementations, the transition arm includes a nose pin and the rotating member is coupled to the nose pin such that axial movement of the transition arm changes an axial position of the piston in the cylinder and causes the nose pin to move relative to the rotating member along an axis other than a central axis of the nose pin.

Abstract: A hydraulic pump includes a housing, at least two pistons mounted to the housing to rotate relative to the housing, and a transition arm coupled to each of the pistons to rotate therewith. The transition arm is set at a predetermined angle relative to a longitudinal axis of the pump. An adjustment mechanism sets the transition arm at the predetermined angle. A cylinder is mounted within the housing to rotate relative to the housing and defines pump cavities for receiving the pistons. A face valve defines inlet and outlet channels in fluid communication with the pump cavities. An apparatus for varying the output volume of a piston assembly includes at least two pistons, a transition arm coupled to each of the at least two pistons, and a rotatable member. The transition arm includes a nose pin, and the rotatable member is coupled to the transition arm nose pin.

Abstract: An assembly includes a piston and a transition arm coupled to the piston. The position of the transition arm is adjustable to vary a stroke of the piston. A balance member is adjustable relative to the transition arm to counterbalance the transition arm in varying positions. A control rod is coupled to the transition arm and the balance member. Linear movement of the control rod moves the transition arm in a first direction to change the stroke of the piston and moves the balance member in a second direction substantially opposite the first direction to counterbalance the transition arm. A method of counterbalancing a variable stroke assembly includes moving a transition arm coupled to a piston to vary a stroke of the piston, and moving a balance member in a direction substantially opposite to the direction of movement of the transition arm to counterbalance the transition arm.

Abstract: An information retrieval application is disclosed which supports digital library functionality, including information retrieval, information manipulation and processing, in distributed data environments (e.g. Grid computing). The application is based on an object model in which data objects (for example, PDF documents) are represented as records in canonical XML form using a schema. These records are stored, distributed around a network, and may be queried using the Common Query Language. Processing objects (for example, preparsers and parsers) may be used to transform data objects into XML records or other data objects, or XML records into one or more data objects. This application defines workflows as objects which can call other workflow objects, allowing for the creation of powerful and flexible parallel configurations.

Abstract: According to the invention, an assembly includes at least one piston assembly (4105), a rotating member (4130), and a transition arm (4110). The transition arm couples the piston assembly (4105) to the rotating member (4130). The assembly includes an overload protection mechanism (4135) coupled to the transition arm (4110) and configured to reduce piston stroke of the piston assembly (4105) upon application of an overload to the assembly while enabling the rotating member (4130), e.g., an input drive and/or a flywheel, to continue rotating. The overload protection mechanism (4135) is configured to reduce piston stroke of the piston assembly to zero stroke while enabling the rotating member (4130) to continue rotating at a substantially pre-overload speed. A method of protecting an assembly from an overload includes reducing piston stroke upon application of an overload to the assembly while enabling the rotating member (4130) to continue rotating at a substantially pre-overload speed.
