The invention discloses a coating material for preventing an engine crankshaft from being locked, and a preparation method and an application method of the coating material. The coating material comprises the following raw materials in parts by weight: PAG (Polyalkylene Glycol ethers) polyether base oil, modified plant-based synthetic ester oxide sunflower oil, epoxy resin, organic molybdenum, tungsten disulfide powder, tungsten diselenide powder, carbon monofluoride powder, polyphenyl, a fire retardant, an antiwear agent and an antioxidant. The coating material is coated on a crankshaft neck surface and/or bearing bush surface between a crankshaft neck and a bearing bush (tile), so that a protective coating which is lubricant enough, and not easy to wash off or damage, and can bearing extremely high temperature is provided under the condition that the engine oil cannot provide effective lubricating due to poor quality, or cannot provide an enough lubricating effect between the crankshaft and a connecting rod due to reduction of the engine oil, the coating material has excellent waterproof properties, anti-rust characteristics, anti-corrosion property, and micro-grinding resistance on metal parts, can form solid dry film lubrication under the environment above 200 DEG C, and can play the roles in lubricating and preventing metal from being locked by sintering at the temperature which can be up to 1400 DEG C, and the locking phenomenon between the crankshaft and the connecting rod caused by dry friction between the tile and the crankshaft is effectively avoided.

A dual-inline neck truss system in a stringed musical instrument is disposed uniformly along the instrument neck, generally toward the rear side, opposite the front side that forms or supports a fingerboard or fret-board. The truss system may be a two-portion single member or two separate in-line members, and is enclosed close to the rear surface of the neck or else with a surface exposed along its full length and made flush with the rear neck surface, smooth to the touch. The truss system is secured to the neck at a designated intermediate location so as to form two substantially co-linear truss portions, either of which can be adjusted for tension independently via manual adjustment hardware for applying pressure against opposite end regions of the neck, thus enabling special desired instrument setup for optimal string-to-fretboard/fingerboard spacing, e.g. providing optimal low “action” with “relief” in the form of special concave curvature contour in a low pitched portion of the neck, particularly advantageous for instruments such as The Stick®, which is designed to be played with two-handed string-tapping technique.

A container having a body portion (10) and a dispensing opening, a neck (14) surrounding said dispensing opening, the neck having a rim (20), an inner neck surface (18) and an outer neck surface (16), and a drip minimizing member (32, 68) extending inwardly over a portion of the dispensing outlet, the member being located proximate the rim (20), the member terminating in a sharp edge (34, 70) to minimize dripping when pouring from the container.

A self-concentric brush seal structure with a rotor provided with discs comprises a brush seal part composed of a fusion welding area, a front baffle, a rear baffle and a brush wire bundle, a stator box, C-shaped seal rings, W-shaped seal rings, wear-resistant coatings, a bearing plate, the front disc, the rear disc and the rotor. The C-shaped seal rings are embedded into the neck surfaces of the front baffle and the rear baffle and are matched with the stator box. The W-shaped seal rings are clamped in the axial direction and the radial direction through the brush seal part and the stator box. The front disc is located at the lower end of the front baffle and is vertically fixed to the surface of the rotor, and the rear disc is located at the lower end of the rear baffle and is vertically fixed to the surface of the rotor. The self-concentric brush seal structure is simple; compared with traditional fixed brush seals, the self-concentric brush seal structure has the advantages that the brush seal part can move freely in the radial direction by being clamped in the stator box through the C-shaped seal rings and the W-shaped seal rings and can move along with the rotor for keeping self-concentric when the rotor moves in the radial direction, and continuous damage caused by direct rubbing between the rotor and the brush seal part can be avoided.

The invention discloses a flat tube necking machine. The flat tube necking machine comprises a machine table and necking puncher pins arranged on the machine table. The machine table is further provided with a steel supporting needle. One end, provided with supporting needles, of the steel supporting needle is arranged between the necking puncher pins. The structure is simple, a flat tube which is cut in the fixed length is placed on the necking machine, the supporting needles of the steel supporting needle are inserted into micro holes of the flat tube, and width necking is carried out. In this way, in the punching necking process, due to the limitation on the pipe wall of the supporting needles, inward collapse cannot be carried out, the outer side is a cold punching forming mold, and only heading can be carried out. The flat necking surface is obtained, and the flatness requirement for brazing can be met.

A tool for breaking a shaft has a first and a second tubular element, both provided with inner through bores adapted to receive a first and second portion of a shaft in a first position of the tool. A first handle is fixedly connected with the first tubular element and the second tubular element is connected to a second handle. A bottom surface of the second tubular element is in contact with a neck surface of the first tubular element forming a shearing plane perpendicular to the main axis of the tool. A rotation between the two tubular elements around this axis creates a twisting movement of the two shaft portions received within the two tubular elements, and shears the shaft portions at the shearing plane. The second handle turns the first tubular element around an axis and has a gear engaging the second tubular element for transmitting the rotation of the second handle into a rotation of the second tubular element for producing the twisting movement.
