Abstract: A pre-loaded cleaning substrate, and related systems and methods for picking up particles with an aspect ratio (L/D) greater than 300 (e.g., hair), or greater than 1200 (e.g., particularly long hairs). The substrate (e.g., a nonwoven) may include only a single layer of material. The pre-loaded substrate is loaded (e.g., during manufacture) with a cleaning composition. The fibers of the substrate may have an average diameter less than 15 ?m, the substrate may have an air permeability of 35 ft3/min to 75 ft3/min, and the liquid cleaning composition may have a surface tension of less than about 50 dynes/cm. Together, the combination of the particular substrate and cleaning composition may facilitate markedly improved ability to pick up high L/D aspect ratio particle debris (e.g., such as hair), while retaining such particles (e.g., providing hair retention index values of at least 20).

Abstract: A screw-tightening tool includes a housing, a spindle, a motor, and a power-transmitting mechanism including a sun member, a ring member, a carrier member and a planetary roller. The power-transmitting mechanism is configured such that, when the ring member moves rearward to be closer to the sun member in response to rearward movement of the spindle, the planetary roller transmits power of the motor to the spindle owing to frictional force between the planetary roller and each of a first tapered surface of the sun member and a second tapered surface of the ring member. The sun member is configured to move from a first position to a second position, which is forward of the first position, when the frictional force reaches a threshold, and to move from the second position to the first position when the frictional force falls below the threshold.

Abstract: A screwdriver includes a main body and a switch. The main body is coupled to a handle and includes a pair of parallel, spaced apart slots, and a pawl positioned in each slot. Each pawl is biased outwardly by a spring. The switch is pivotable relative to the main body, and the switch includes a groove extending along an arcuate portion of an inner surface. Pivoting the switch in a first direction moves the switch toward a first position in which the groove is positioned in-line with the first pawl. When the switch is in the first position, the first pawl extends outwardly from the slot and engages the internal tooth surface such that application of a torque in a first direction drives a shank in the first direction and application of a torque in the second direction causes the shank to ratchet relative to the main body.

Abstract: A pipe wrench is provided with an extendable handle that fits within a cavity of the head. A lever locks the extended length of the extendable handle along a continuous spectrum between a maximum and a minimum extension of the handle. The lever includes cam surfaces. In an unlocked position, the thickness of the lever between the pivot and a friction plate is less than the thickness between the pivot and the friction plate in the locked position. The friction plate is a composite comprising a top lever plate, a midsection, and a concave surface. The lever plate and concave surface include hard, durable materials, and the midsection is a soft elastic material that redistributes frictional forces across the frictional block. The channel-lock prevents inadvertent overextension and/or accidental removal of the extendable handle.
