摘要： A controllable capillary pump utilizing groupings of capillary tubes. Since individual capillary tubes produce different flow rates depending on their diameter, length and cross-sectional shape, it is possible to control the flow rate by providing different groups of capillary tubes. These groups may be included on a rotating cylinder so that a selection may be made merely by rotating the cylinder.

摘要翻译： 利用毛细管分组的可控毛细泵。 由于单独的毛细管根据其直径，长度和横截面形状产生不同的流速，因此可以通过提供不同组的毛细管来控制流速。 这些组可以包括在旋转圆筒上，使得可以仅通过旋转圆筒来进行选择。

摘要： A handle has a box end with an internal wall that confines a through-bore to receive movably a pair of identical rollers. The rollers has an eccentric shaft fixed between them and a central rectangular opening that extends through the eccentric shaft. An annular space formed around the eccentric shaft and confined by the internal wall of the box end includes a widest portion with a first length on one side of the eccentric shaft and a narrowest portion with a second length formed on the other side of the eccentric shaft. A plate is fixed perpendicularly between the rollers. A compression spring has one end secured to the plate. A cylindrical member with a diameter that is smaller than the first length but larger than the second length is disposed between the rollers. A second end of the compression spring connects securely the cylindrical member and biases the same such that the cylindrical member is located between the widest and narrowest portions wherein the cylindrical member frictionally abuts the internal wall of the box end and the eccentric shaft. The rollers are retained in the through-bore by a pair of retaining plates.

摘要： A buckle assembly includes a first buckle member having an insertion member, a second buckle member, a first buckle latch, a second buckle latch, a plurality of resilient elements, and a locking arrangement. The locking arrangement includes at least two locking protrusions and at least one guiding member. The locking protrusions are extended from one of the insertion member and the second buckle body, and are arranged to form a locking channel between the two locking protrusions. The guiding member is extended from the remaining one of the insertion member and the second buckle body, and is arranged to be inserted in the locking channel formed by the locking protrusions so as to retain the first buckle member to be locked with the second buckle member when the first buckle latch and the second buckle latch are in the locked position.

摘要： A leg stretching device includes a base unit, a connecting frame, a control mechanism, and a pair of leg support rods. The control mechanism includes a slide rod having a frame connecting portion mounted non-rotatably on the connecting frame, and a rack portion extending slidably into a stationary tube of the base unit. A ratchet wheel is mounted rotatably on the stationary tube and meshes with the rack portion. A control lever is mounted pivotally on the stationary tube, and a pawl unit is mounted on the control lever. The pawl unit engages the ratchet wheel to transmit a forward turning force applied on the control lever to the ratchet wheel, thereby enabling the ratchet wheel to rotate in a direction for retracting the slide rod into the stationary tube, and disengages the ratchet wheel when a rearward turning force is applied on the control lever. Each of the leg support rods is mounted pivotally on the connecting frame at one end, and is provided with an ankle support at the other end.

摘要： A torsion wrench includes a tubular casing, a drive unit pivoted to the casing and adapted to engage a workpiece, a knocker for generating an alarm sound when torsion force that is applied by the drive unit on the workpiece reaches a predetermined torsion force limit, a biasing unit for biasing the knocker toward the drive unit, and an adjusting unit for adjusting initial biasing force of the biasing unit. The biasing unit includes a push piece and a spring disposed between the push piece and the knocker. The adjusting unit includes a tubular handle member which has a connecting end sleeved rotatably on one end of the casing, and a push rod unit having a first end portion extending into the handle member and a second end portion extending into the casing and connected to the push piece. Rotation of the handle member results in axial movement of the push rod unit in the casing. A torsion force detecting unit includes a sensor unit for generating an electrical signal corresponding to position of the push piece in the casing, a converter circuit for converting the electrical signal into a digital reading of the predetermined torsion force limit, and a display unit for displaying the digital reading thereon.
