摘要:
A tube-bending plier is described having opposing arcuately grooved registering jaws defining a cylindrical engagement segment sized to accept tubing of a particular outside diameter, expanding to oppositely curving arcuately grooved side-jaw mandrel surfaces where, (i) in a first embodiment, the plier handles extending from the plier couple are configured for significantly increasing the distance between the handles for applying torque (τ) relative to a twisting axis aligned in the plane of and extending between the plier handles pivotally closing plier jaws for bending a tube held perpendicularly extending from the plier jaws, and (ii) in a second embodiment, the closed plier jaws and oppositely curving side-jaw mandrel surfaces define a tube bending plane oriented at an acute angle relative to the plane of the pivoting plier handles for applying torque (τ) for bending a tube held within the plier jaws.

A pair of linkage bushing installation pliers includes two pivotally coupled, elongated handles with opposing clamping jaws, one presenting an annular clamping anvil for engagement around a receiving aperture on one side of a lever, the other presenting a seating anvil having a perpendicularly extending stool for coaxially forcing a linkage bushing, coaxially placed around the stool, into and through the receiving aperture from the opposite side of the lever.

A dual drive bit is formed as an integral body which includes a drive end which is shaped and configured for engagement with a fastener and an opposite driven end. The driven end includes an internal socket and an external, shaped surface enabling the drive bit to be driven by engaging the internal socket by a socket drive or externally by a wrench. Intermediate the drive end and the driven end is an intermediate or medial section of the body which includes a flange that extends at least in part radially beyond the circumference of the driven end to enable a user to positively engage the driven end and force it axially into engagement with a fastener.

A magnetic pick-up tool is described having a first, small diameter, high field strength permanent magnet pellet, permanently secured within a holder presenting a pole face at a distal tip of a probe extending from a handle, and at least a second, removable, small diameter, high field strength permanent magnet pellet stored, seated adhering in a receptacle located in the proximal end of the handle having a bottom composed of a high magnetically susceptible material.

A two component, curable hot melt adhesive system includes a first hot melt adhesive formulation which has a softening temperature greater than room temperature and which includes a first component of a curable adhesive therein. The system includes a second hot melt adhesive formulation which has a softening temperature which is greater than room temperature and which includes a second component of a curable adhesive therein. The second component is reactive with the first component to provide a cured adhesive bond. In use, the two formulations are heated to a temperature above their softening temperature and are contacted so as to cause mixing. The mixture cools to provide a thermoplastic bond which subsequently cures to provide a permanent adhesive bond. While the first and the second component individually perform as hot melt adhesives, combining the first and the second gives enhanced adhesive performance in extended temperature ranges.

A light emitting control device for a light emitting diode print head includes a control unit, a pulse-mask unit, a strobe unit and a data output unit. The pulse-mask unit outputs n clock signals in sequence to a light emitting diode print head. The strobe unit outputs a strobe signal to the light emitting diode print head, so as to switch on the light emitting diode print head. The data output unit outputs a print data signal to the light emitting diode print head. When the pulse-mask unit outputs a k-th clock signal of the n clock signals, the pulse-mask unit delays the k-th clock signal for a predetermined time, and the data output unit pauses outputting the print data signal. After the predetermined time, the pulse-mask unit and the data output unit continue to output the rest of the clock signals and the print data signal.
