    Abstract: A hydraulic damper for a high speed actuator is provided to bring the actuator to rest with minimum oscillation around a target position. The hydraulic damper comprises a hydraulic circuit to communicate with the actuator over its entire positional range for the purpose of dampening a sudden stop of the actuator about a target position. The actuator is connected by a cable to a reel, the reel being connected to a shaft movement of the actuator produces rotation of the shaft. The shaft is also connected to a hydraulic motor which pumps hydraulic fluid through a hydraulic damper too, in effect, dampen the movement of the actuator.

    Abstract: An apparatus (10) for providing rotary and linear motions, either simultaneously or separately. The apparatus (10) includes a rotary table assembly (14) that interconnects a rotary actuator assembly (12) and a power cylinder (18) or a comparable device. The rotary table assembly (14) includes a rotatable hub (16) to which the power cylinder (18) is mounted. Rotation of the hub (16) causes rotary motion of the entire power cylinder (18). Because of the interconnection between the rotary actuator assembly (12) and the power cylinder (18) using a rotary table assembly (14), a modular construction is provided whereby the power cylinder (18) can be positioned both vertically and laterally, depending upon the application or intended use of the apparatus (10). In one preferred embodiment, the rotary actuator assembly (12) converts linear movement to rotary motion using hydraulic oil to provide a smooth, adjustable control of the rotary shaft (32) of the rotary actuator assembly (12). Hydraulic oil is located in a reservoir unit that is connected contiguously adjacent to the tandem cylinders (82 and 84) of the rotary actuator assembly (12).

    Abstract: An improved double-acting fluid cylinder with primary and secondary chambers of tandem construction, wherein the primary chamber is utilized to provide ram motion in a first direction and wherein the tandemly arranged secondary chamber is provided with a single biasing spring means to resiliently bias the secondary piston and to buffer and control the rate of motion induced in the ram, and also to drive the ram in a direction opposite the stroke of the first direction and at a time subsequent to the stroke so as to temper the ultimate amplitude or extent of motion induced in the ram in response to forces applied within the primary chamber.
