Abstract: A calcium hydroxide unit-dose multi-package and method of forming the package that includes sealed chambers or compartments each containing a capsule having a connected needle forming a nozzle which is open at the discharge end. The capsule is pre-filled with a predetermined amount of calcium hydroxide formulation that is confined within the capsule by an end plug that functions as a piston to extrude the calcium hydroxide formulation from the capsule and directly to the tooth when used. Disposed within the sealed chamber or compartment containing the capsule, is a quantity of preservative liquid or distilled water saturated with calcium hydroxide to prevent dehydration or decomposition of the calcium hydroxide formulation in the capsule during shipping or storage. The multi-package with the capsule and liquid sealed therein can be sterilized by gamma radiation to ensure sterility of the calcium hydroxide and to prevent growth in the sealed container. The multi-packaged is formed as a tray having multiple chambers, each of which contains pre-loaded capsules and a quantity of preservative liquid whereby the respective chambers are sealed by an overlying cover sheet.

Abstract: A high pressure check valve assembly includes a ceramic cage loosely fitted into the bore of a body so as to leave at least a partial clearance between the cage and the body. A passage through the cage includes a retaining section adjacent a fluid inlet end for loosely containing a ball and an irregular cross-section adjacent the retaining section so as to obstruct the ball without hindering fluid flow forwardly through the passage. The cage further has a lateral bleed hole between the passage and the clearance to equalize fluid pressure. An outlet-end sealing member is press fitted into the bore against the outlet end of the cage. An oversized resilient washer-shaped inlet-end sealing member is press fitted into the bore against the inlet end of the cage to seal and retain the assembly. This member has a central aperture with a washer shaped seat member fitted therein, the seat member functioning with the ball as the check valve.

Abstract: A transducer for measuring extremely small rates of flow of a liquid under high pressure. A transparent tube has a small channel within which is contained a ball having a diameter substantially that of the channel. The tube is housed in a pressure vessel in such a manner that the high pressure liquid to be measured surrounds the tube over most of its length. The liquid flows externally of the tube toward the inlet end of the channel, thereby equalizing the pressure differential within and without the tube. As the fluid passes through the channel from the inlet to the outlet, it propels the ball past a sensor, such as a photoelectric device. The velocity of the ball past the sensor indicates the volumetric flow rate of the fluid. The device is periodically reset by momentarily reversing the direction of flow through the tube to return the ball to its starting position.
Abstract translation: 用于在高压下测量液体的极小流量的换能器。 透明管具有小通道，在该通道内容纳有直径基本上为通道直径的球。 将管以这样的方式容纳在压力容器中，使得待测量的高压液体在其大部分长度上围绕管。 液体从管的外部流向通道的入口端，从而使管内和外管之间的压力差平衡。 当流体从入口通过通道到出口时，其将推动球通过诸如光电装置的传感器。 通过传感器的球的速度表示流体的体积流量。 通过瞬间反转通过管的流动方向来定期复位装置，以将球返回到其起始位置。

Abstract: A liquid pump motor control for a liquid chromatograph. The control detects when the pump needs to be refilled. Then, the pump motor is accelerated at a first rate for a given number of pulses. Then the motor is accelerated at substantially its maximum rate until a selected maximum speed is reached. Thereafter the speed is maintained at its maximum until the time calculated to begin deceleration. The motor is then decelerated substantially at its maximum deceleration rate until the speed is close to the final desired speed. Then deceleration occurs at a slower rate for a fixed number of pulses. The number of pulses applied to the stepping motor from the beginning of acceleration until the end of deceleration is constant regardless of the beginning or ending pulse rates.
