摘要： The head, rolling diaphragm, intake and discharge ports form a single module, separate and easily removable from the principle cylinder of a rolling diaphragm filling unit. The rolling diaphragm may be fixed or removably attached to the head. Intake and discharge valves of various types may be mounted directly in the head, or may be mounted remote to the head module and fluidly connected directly to the head by tubing. Flanges of the rolling diaphragm provide an air and liquid tight seal between the head and base and removably attached to the head so as to facilitate visual inspection of the product contact surfaces of the head cavity prior to clamping the head module to the base.

摘要： A gear pump for dispersing a gas into a liquid is provided with mixing means for improving the uniformity of the dispersion. In preferred form, the mixing means comprises a series of fixed, shallow, blind cavities that open to the pumping cavity between the liquid inlet and the outlet, and which are positioned to be "wiped" by the gear teeth as the gears rotate. The alternate connection and disconnection of the intertooth spaces to these cavities as the gears rotate establishes motion or turbulence of the gas/liquid mixture within the intertooth spaces, and surprisingly improves uniformity of the dispersion.

摘要： A metering pump wherein the head is provided with internal threads terminating adjacent to internal shoulders at each of the pump cylinder, inlet valve and outlet valve ports. The cylinder, inlet valve and outlet valve each include a flange secured to the shoulder by a collar threadably received in each of the ports. O-rings are provided in a circumferential groove in the body or cylinder of the pump inlet valves and outlet valves downstream of the flange. A piston pump structure includes a bushing mounted to the piston rod between the piston head and a second breakaway stop connected to the piston rod. The piston head includes a plurality of circumferential grooves for receiving respectively a cup seal or an O-ring seal. A suck-back mechanism is provided in a bore in the head and includes a stem having an eccentric cam which interacts with the valve structure to adjust the degree of closure by rotation of the stem.

摘要： Devices, especially orthotic, prosthetic and manipulative devices, articles of wear, and apparatus utilizing a coil spring are provided for self-adjustable support, flexion, and/or extension of limb members of a body joint. The devices have first and second support arms each having a planar face at one end joinable in co-axial face-to-face relation at a pivot point, in combination with a coplanar co-axial coil spring allowing for flexion and extension. The respective faces in one preferred embodiment have a range-of-motion guide channel and a channel-following stop member and at least one groove pair located on opposite sides of the channel for holding a stop bar across the channel to limit the range of motion of the stop member in the channel. In another preferred embodiment, one planar face has angularly spaced locking slots and the other has a pivotable locking blade that can be inserted into a selected locking slot and the edge of one of the planar faces has beveled guides enabling the coil spring under compression to be guided centrally to a position aligned with the planar faces.
