A self-adjusting pushrod length checking tool for use in an internal combustion engine between the camshaft lifter and valve rocker arm, that determines the optimum pushrod length using a telescoping spring-loaded body upper rod and a lower rod assembly. The spring-loaded telescoping assembly self-adjusts and determines the optimum pushrod length when compressed and inserted between the camshaft and valve rocker arm, when the rocker arm pivot bolt is fully tightened down to the cylinder head. The telescoping assembly sections are then locked by a captive set screw, the assembly is removed from the engine, and accurate measurements of the assembly length are taken.

A system configured to inspect a processing apparatus includes a temperature adjusting device configured to adjust a temperature of a component within a processing chamber of the processing apparatus; a light source configured to emit measurement light; multiple optical elements configured to output the measurement light emitted from the light source to the component within the processing chamber of the processing apparatus as output light and configured to receive reflected light from the component during a temperature adjustment of the component by the temperature adjusting device; and a controller configured to measure temperatures of the component at measurement points respectively corresponding to the multiple optical elements based on the reflected light, and make a determination upon abnormality of the processing apparatus based on comparisons of the temperatures of the component at the respective measurement points.

A measuring equipment, applied to carry a workpiece to be measured, includes a main base and a positioning device. The main base includes a measuring center axis. The positioning device includes at least two positioning elements. Each of the at least two positioning elements is disposed movably on the main base, and each of the at least two positioning elements is moved with respect to the measuring center axis. An identical distance is there from each of the at least two positioning elements to the measuring center axis. Each of the at least two positioning elements is used for the workpiece to contact and to be positioned to the measuring center axis.

Provided is a rail head abrader including a base, a blade, a vertical measurement section and a horizontal measurement section; an upper end surface of the base is arranged horizontally and a base bevel edge intersects a base vertical edge; the blade is disposed on the base and perpendicular to the upper end surface of the base, an upper portion of the blade is provided with vertical wear rail type selection lines; the vertical measurement section includes a vertical scale frame, a vertical digital display device, and a vertical scale cursor; the horizontal measurement section includes a horizontal scale frame, a horizontal measuring rod, measuring rod rail type selection lines, a horizontal digital display device, and a horizontal scale frame cursor, and a horizontal scale frame cursor locating line corresponding to the side wear rail type selection lines; the horizontal measuring rod is slidably mounted on the horizontal scale frame.

A calibrated three-dimensional optical measuring apparatus for three-dimensional measurement of geometric parameters of a rope has a frame defining and arranged around a rope receiving cavity. Image acquisition devices acquiring digital images of regions of an outer surface of the rope are fixed to the frame and arranged around the rope when the calibrated three-dimensional optical measuring apparatus receives the rope in the rope receiving cavity. An electronic digital image processing device processes a multiplicity of digital images and obtains a three-dimensional photogrammetric reconstruction of points of the digital images of the rope. Having defined a circumferential direction running around a main extension axis of the rope and lying on a plane incident or perpendicular to the main extension axis of the rope, the image acquisition devices are arranged on the frame circumferentially spaced apart from one another along the circumferential direction. A lighting device is arranged along the circumferential direction between a pair of adjacent image acquisition devices.

A device and method for identifying a center of a striking face of a golf club head are disclosed. The center determining device includes a device body having a central opening defined through a first surface of said device body and a second surface opposite said first surface. A first dimension indicator including a pair of first indicator jaws and a second dimension indicator including a pair of second indicator jaws may be disposed on said device body. A first adjuster and a second adjuster are operable to adjust said first separation distance said pair of first indicator jaws and a second separation distance between said second indicator jaws. When the pair of first indicator jaws and the pair of second indicator jaws are equally spaced around the heel, toe, topline, and sole edges of the striking face, the central opening is aligned with the center of the striking face.

A brake wear gauge assembly includes a plurality of wires that is each comprised of a bendable material such that each of the wires is retained in a desired shape for guiding between a brake rotor of a vehicle and a brake pad of a vehicle. A ring is provided that has each of the wires movably disposed thereon thereby facilitating the plurality of wires to be portable.
