Abstract: A handheld clamping tool includes a sliding bar, a bracket selectively and detachably coupled to one of two opposite ends of the sliding bar and providing a first jaw, a handle holder affixed to the sliding bar and providing a second jaw, a driving handle operable to move the bracket relative to the handle holder, and a control knob including a male knob member and a female knob member coupled together in a horizontal bottom hole of the bracket, a pin affixed to the female knob member and movable with the female knob member in and out of a lock hole at one end of the sliding bar to lock/unlock the bracket and the sliding bar, and a compression spring mounted between the male knob member and the bracket to support the male knob member in the locking position where the pin is inserted through the lock hole.

Abstract: A handheld clamping tool includes a sliding bar, a fixed handle having installed therein actuation plates, a stop plate, spring members and a release bar, a driving handle, a coupling rod coupling the actuation plates and the stop plate, and a first jaw holder. The driving handle has an integrated cam portion for driving the actuation plates and the stop plate. By means of the release bar, the handheld clamping tool can be quickly released.

Abstract: A finger pinch preventing hand-held quick-clamping device includes a shifting lever, a fixed handle, a drive handle, a jaw holder, a first jaw affixed to the jaw holder, a second jaw affixed to the fixed handle, a movable stop block set in the fixed handle and a release lever having a triggering tip adapted for moving the movable stop block into stoppage against the drive handle to keep a predetermined gap between the drive handle and the fixed handle and to prevent finger pinch when the release lever is biased to release the workpiece.

Abstract: The viscosity or relative viscosity of samples can be measured in parallel by dispensing or aspirating the samples at a set condition and then measuring a property of the sample such as mass dispensed or aspirated.

Abstract: A turbidity measurement system includes a sample assembly that contains a plurality of samples, a light source that illuminates the sample assembly, and a light detection system that includes a two-dimensional light-sensitive array. The light-sensitive array is simultaneously exposed to light transmitted through each of the samples in the sample assembly. The exposure is analyzed to determine a mean transmitted light intensity for each sample and to calculate a turbidity value for each sample based on its mean transmitted light intensity. Multiple exposures may be taken during a measurement period so as to obtain time-resolved turbidity measurements of the samples. The temperature of the samples may be varied during the measurement period so as to measure turbidity as a function of temperature.

Abstract: A hand held quick-clamping device includes an adjusting rod, a retaining handle, a driving handle, a first clamping block, and a second clamping block. The adjusting rod intersects the retaining handle, a set of adjusting sheets, and the stop sheets. A first clamping block is locked in a predetermined end of an adjusting rod, and a second clamping block is formed on a top end of the retaining handle. A driving handle is pivoted to the retaining handle. A traveling top shaft is installed in the retaining handle, and an axial shaft is opposite to it. While the driving handle is pressed, a top end of the driving handle pushes the top shaft. Through the top shaft, the axial shaft pushes the adjusting sheets and the stop sheets. And the movement of the sheets will drive an adjusting rod to move in one direction, thus producing a clamping or extending function.

Abstract: A hex wrench includes a wrench body, which has a handle, a head, a bent portion connected between the handle and the head, a handle work tip at the free end of the handle, and a head work tip at the free end of the head, a long hexagonal plastic sleeve tightly wrapped about the handle, and a short hexagonal plastic sleeve tightly wrapped about the head.

Abstract: A fluid circuit includes a membrane having a first side, a second side opposite the first side, and a pore extending from the first side to the second side. The circuit also includes a first channel containing fluid extending along the first side of the membrane and a second channel containing fluid extending along the second side of the membrane and crossing the first channel. The circuit also includes an electrical source in electrical communication with at least one of the first fluid and second fluid for selectively developing an electrical potential between fluid in the first channel and fluid in the second channel. This causes at least one component of fluid to pass through the pore in the membrane from one of the first channel and the second channel to the other of the first channel and the second channel.

Abstract: A storage kit for hex keys includes a barrel having one end provided with multiple blind holes each adapted with a channel to hold a hex key to help apply torque as a handle; and a cap holding hex keys together in the barrel to be pulled out of or inserted into the barrel at the same time; channel by; and another end of barrel having multiple insertion holes to store tips of other hand tools such as a screwdriver for the kit to function as the handle of the screwdriver.
