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： 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 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.
摘要翻译：设备，特别是矫正器，假肢和操纵装置，磨损制品和使用螺旋弹簧的装置被提供用于身体关节的肢体构件的自我调节的支撑，弯曲和/或延伸。这些装置具有第一和第二支撑臂，每个支撑臂在一个端部处具有平面，该平面在枢轴点处以同轴面对面关系连接，并与允许屈曲和伸展的共面同轴螺旋弹簧组合。一个优选实施例中的各个面具有一个运动范围的引导通道和通道跟随止动构件以及位于通道的相对侧上的至少一个凹槽对，用于在通道上保持止动杆以限制运动范围的通道中的停止成员。在另一个优选实施例中，一个平面具有角度间隔开的锁定槽，另一个具有可枢转的锁定刀片，其可以插入到选定的锁定槽中，并且其中一个平面的边缘具有使压缩的螺旋弹簧成为中心地引导到与平面对准的位置。
