The hardfacing alloy has a low coefficient of friction resulting from excellent metal to metal resistance and significant reduction in industrial wear on industrial products, such as casing wear. Other embodiments of the invention include tool joints having the hardbanding alloy welded to the outer cylindrical surface to its box and pin members and to stabilizer ribs on the stabilizer used in earth boring, such as boring for oil and gas, other industrial products, and methods of applying the hardfacing alloy to their surfaces. The hardfacing alloy does not require any post weld treatment, has primary bondes in its microstructure, the carbons in the alloy are tied up in the formation of secondary carbides which add to the abrasion resistance, and have a quadratic crystallographic structure and a hardness of about 1725 Hv comparable to the prior art hardness of the chromium carbide primary carbide alloys of the prior art but is substantially less brittle than C-Cr-Fe hardfacing alloys.

Two-part, remotely-controlled, three-dimensional toy

ABSTRACT OF THE INVENTION A two-part, remotely-controlled, three-dimensional toy is disclosed which comprises a base and a play-unit interchangeably connected to the base. A receiving unit on the base receives control signals from a control means which is remote from the toy. The control signals control the movement of the toy and they also control the activity of various play-elements on the play-unit. Because the play-units are interchangeable, many different qames may be played with the same base and control unit. The invention provides an alternative form of toy.

Liquid crystal display device

In a liquid crystal display comprising a plurality of pixels each of which has an switching element, a plurality of drain drivers and gate drivers for operating the switching elements and the pixels, and a plurality of drain lines and gate lines supplying signals from the drain drivers and the gate drivers to the switching elements being formed on one of a pair of substrates sandwiching a liquid crystal layer, the present invention provides wiring lines formed on the one of a pair of substrates for transferring display data signals and a clock signal between each pair of the plurality of drain drivers adjacent to one another, and provides at least one gate circuit for at least one of the plurality of drain drivers which is controlled by the clock signal and switches the display data signals and the clock signal either (1) to be acquired by the at least one of the plurality of drain drivers or (2) to be transferred to another of the plurality of drain drivers arranged adjacent to the at least one of the plurality of drain drivers. This liquid crystal display device has an advantage, for instance, or of suppressing electromagnetic interference (EMI) to another equipment surrounding the liquid crystal display device, of preventing the display data signals or the clock signal from being distorted in the wiring lines.

Multi-blow pneumatic hand tool for inserting t-nuts

A portable device (10) for inserting fixing elements (100) into predefined seats (210) in a work piece, the portable device including a drive head (12); a drive rod (20) extending downward from the drive head; a hollow nose piece (50) slidably fit around a lower end of the drive rod, the nose piece being attached to the head and being movable vertically by a predetermined distance with respect to the head and the drive rod; a magazine (60) mounted on the nose piece at a predetermined angle with respect to a lower face of the nose piece for feeding a first t-nut fixing element into a horizontal slot (52) on the lower face the nose piece; and a drive mechanism providing a pulsating force produced by a pressurized fluid to an upper end of the drive rod when downward pressure is applied by a user on the drive head. The pulsating force on the drive rod drives the first t-nut fixing element into the predefined seat in the work piece.
