A rotary platform device is for supporting and rotating an assembly. The rotary platform device includes a rotary platform and a casing. The rotary platform extends up from the casing. The casing accommodates a driving device, a coupling member, and a linkage bar. The driving device provides linear motion, which is translated by the linkage bar to rotary motion applied to the rotary platform.

A vernier adjustor for a conveyor system is provided. The vernier adjustor includes first and second longitudinal members moveable in slidable relation and a pin, the first and second longitudinal members each including a plurality of slots separated by respective first and second spacings. The pin is adapted for placement within an aligned slot pairing to fix movement of the first longitudinal member relative to the second longitudinal member. The first and second longitudinal members are positionable in increments less than the first and second spacings. In particular, the first and second longitudinal members are positionable in increments substantially equal to the difference between the first spacing and the second spacing. Movement of the first longitudinal member relative to the second longitudinal member provides an incremental tensioning of an endless belt associated with the conveyor system.

A metering pump includes an actuating mechanism, and a plurality of piston cylinders coupled to the actuating mechanism. A first of the cylinders has a working volume that differs from a second of the cylinders. The actuating member is centrally located and the cylinders are arranged radially about the actuating mechanism. The working volume of the cylinders can be varied by adjusting the spacing of the cylinders from the actuating mechanism, thus varying the stroke of pistons housed within the cylinders, and/or by providing the cylinders with different inner diameters. A method of metering fluids includes independently adjusting stroke of a plurality of pistons to adjust the volume of metered fluid, and selecting different cylinder diameters to adjust the volume of metered fluid.

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.

An apparatus for mutual conversion between circular motion and reciprocal motion includes a lever member which is rotatably mounted on a line connecting a rotational center and a circumference of a rotary disk, the lever member having a fulcrum, an action point and a force point, and being provided with a first regulator serving as an action point regulator and a second regulator serving as a movable fulcrum regulator. The first regulator is coupled to a reciprocating body. The movable fulcrum regulator has support members for supporting the fulcrum point and the first regulator has support members for supporting the action point in a longitudinal direction of the lever member.

An engine for generating rotational torque through the oscillating movement of lever arms. The inventive device includes an elongated cylinder having first and second opposed cylinder heads. A pair of pistons are oppositely disposed within the cylinder and coupled together by a connecting rod. At least one lever arm is pivotally mounted at a first end thereof to the connecting rod between the pistons. The lever arm is also pivotally mounted at a medial portion thereof exterior of the cylinder to a mounting plate. A flywheel is rotatable mounted to the mounting plate and engages a second end of the lever arm, whereby oscillation of the lever arm in response to piston movement is translated into rotational movement of the flywheel.

An improved technique for balancing inertia forces and rocking couples of a Ross-type Stirling machine (U.S. Pat. Nos. 4,138,897; 4,532,819 and 4,738,105). Two counter-rotating balance masses are used, one on the crankshaft and one on a separate balance shaft. These balance masses lead the throw of the crankshaft by more than 180 degrees of rotation. The axis of the balance shaft is positioned so that a line connecting it and the axis of the crankshaft is inclined with respect to the cylinder axes toward the heavier piston of the machine. The new technique is also applicable to other machines having separate parallel cylinders in which pistons of unequal mass reciprocate out of phase.

A transmission mechanism for a scroll sawing machine is disclosed. An upper counter weight and a horizontal counter weight are secured to the lower end of a rocker arm, which has its top end secured to the scroll saw blade upper driving arm, and carried to move by the transmission shaft of a motor. The rotation of the transmission shaft of the motor drives the upper counter weight to rotate so as to eliminate any possible vertical shock waves, and simultaneously drives the rocker arm to move up and down so as to eliminate any possible horizontal shock waves.
