A coupling device for engaging an exchangeable tool support ( ) for corotation with a shaft ( ) of a motor ( ), with the shaft ( ) mounting at is driven end a hollow shaft projection ( ) for receiving the tool support ( ). Alternatively, the tool support ( ) can mount the hollow shaft projection for receiving the driven end of the shaft. The shaft ( ) and/or the tool support mounts a locking device for securing the tool support ( ), and which is actuated by centrifugal force. The coupling device is designed and constructed so as to permit a simple mounting of even heavy tools to the output shaft of the motor, and a reliable connection of the tool and drive.

Coupling device

An apparatus for inserting twist into a moving strand, including a first body including an orifice extending therethrough for permitting passage of a moving yarn. An air channel extends therethrough and communicates with the orifice. The air channel communicates with the orifice at a tangentially-offset angle to the path of the yarn through the orifice to create a cyclonic air circulation pattern in the orifice to insert a predetermined direction of twist into the yarn as the yarn passes through the orifice. The first body is adapted for being inverted relative to, and placed in overlying registration with, a second like body whereby the air channel of the first body inserts one predetermined direction of twist into the yarn and the air channel of the second body inserts another predetermined direction of twist into the yarn.

Fluid-jet twist-inserting apparatus and method

The surface inspection system has a scanning head for scanning the laser beam along a predetermined scan line across the surface of an article. A collector receives the light reflected from the article surface along the scan line. The collector has a first mirror position for receiving light reflected from the article surface, a second mirror oriented with respect to the first mirror to receive light reflected from the first mirror, and the first and second mirrors being configured and oriented so as to concentrate the reflected light from a line into a spot. A photodetector is positioned for receiving the thus formed spot of light. The method of inspecting the surface of an article includes the steps of scanning a laser beam along a predetermined scan line across the surface of the article, collectively receiving the light reflected from the article surface along the scan line with a plurality of mirrors so as to concentrate the reflected light from a line into a spot.

Particle detection system with reflective line-to-spot collector

The invention relates to an inspection system for inspecting the surfaces of wafers, LCD's and film substrates for flaws. The system includes a scanning laser inspection system for quickly inspecting the surface and identifying and locating the flaws. The system generates and displays a flaw map graphically illustrating the article surface and the respective locations of the flaws for subsequent optical inspection. The operator selects a flaw and an optical inspection system is positioned over the selected flaw to provide a magnified image of the flaw. The operator may optically inspect all or any number of the flaws. The invention also includes means for spectrometrically analyzing the reflected light to further identify the flaw.

Method and apparatus for low angle, high resolution surface inspection

A laser light inspection device for inspecting opposite surfaces of a workpiece with a low angle laser light beam. The laser light beam is directed in successive scans of a first and second sides in a repetitive manner using a pair of dividing mirrors and a pair of low angle mirrors. Light reflected by any debris back toward the direction of origin of the light beam is collected and analyzed.

Method and apparatus for inspecting reticles

The present invention provides a laser scanning system of compact size and relatively long focal length which may be used in laser surface inspection system for silicon wafers and the like. The scanning system employs a folded optical cell having a pair of reflective surfaces so oriented that the scanning laser beam is folded, and reflects from each of the reflective surfaces several times to significantly increase the focal length. The folded optical cell is also effective to produce a collimated, substantially parallel scan pattern such that the beam remains perpendicular to the inspection surface as it is scanned. The folded optical cell can also be set for divergent or convergent scan.

Compact laser scanning system

A generator load curve is precisely matched to a wind-driven motor characteristic by means of a rotor speed-responsive tachometer effecting stepwise control of field current in the generator. Several variations of the tachometer circuit are described. Field current is controlled by an amplifier, and voltage regulation is effected by an override circuit disabling the amplifier.

Load control for wind-driven electric generators

In the rotor of a windmill electric generator, blades are secured to a hub by means of individual tab-receiving slots and a common 'knock-off' hubcap, this mounting means providing for rapid assembly and disassembly. The mounting structure itself establishes a predetermined pitch at the blade root, thus permitting the advantages of an optimum twisted blade to be obtained without the need for an excessively complex blade configuration. The result is a compact generator unit that can be used easily in remote areas and stowed with camping equipment.
