摘要:
Disclosed is an apparatus and method for verifying the treatment of molten metal wherein a sensing device detects an in situ response resulting from the treatment of the molten metal. The in situ response is compared to a pre-set limit or condition in order to determine whether or not proper treatment of the molten metal has occurred. In particular, the sensing device detects an in situ response resulting from the mixture of a molten metal addition to a molten metal. An electronic transformation device can be used to transform the in situ response into a response data set. The response data set can be transmitted to and received by a microprocessor. The microprocessor can manipulate the response data set. The in situ response to the treatment of the molten metal can be in the form of heat, light intensity, light wavelength, density of smoke particles, composition of smoke particles, mechanical vibration and combinations thereof.

A golf ball is provided that has a hard sphere core or layer that exhibits a controlled vibrational response. The vibrational response may be controlled by tailoring the stiffness or damping of the sphere with at least one element, such as a groove(s) or any other type of indentation in the hard sphere core. The groove (or grooves) serves to locally reduce the wall thickness of the hollow metal sphere core, thereby reducing the stiffness of the core by allowing larger deformations under a load without significantly reducing the total mass of the core. This results in a golf ball that is legal for play and capable of drive distances essentially equivalent to those of currently available high performance golf balls, but that also maintains a high moment of inertia, allowing less hooks and slices during play.

A miter saw assembly comprises a cutting tool configured to perform a cut along a cutting axis. A fence of the miter saw assembly extends longitudinally in a direction transverse to the cutting axis. A stop mechanism is linearly translatable in the longitudinal direction of the fence. A rotary motor includes a selectively rotatable rotor and a motion conversion mechanism is configured to transform rotary motion of the rotor to linear motion of the stop mechanism in the longitudinal direction of the fence. A controller is configured to selectively rotate the rotor to cause linear translation of the stop mechanism in the longitudinal direction of the fence toward or away from the cutting axis.

A method for calibrating a CNC machine including providing instructions for machining a surface of a distortion-free object, selecting a true axis of movement of a toolhead of the machine using the instructions, instructing the toolhead to travel on an object to be machined along the true axis of movement, but where the toolhead actually travels along an actual axis that is deviated from the true axis as a result of the surface distortions on the object to be machined, selecting multiple points along the actual axis traveled by the toolhead on the object to be machined, comparing the distance of the multiple points along the actual axis from the true axis to determine offset amounts from the true axis corresponding to a lack of straightness of the object to be machined, and modifying the instructions to compensate for the offset amounts before uploading the instructions to a CNC controller.

A computer system and method is disclosed for mining current and archived address data in order to identify a preferred address for each service point in a territory. The data mining system may start in response to the presentation of a candidate address for matching. The set of mined data may be prioritized by clustering like characteristics, building similarity matrices, and by constructing dendrograms with nodes joined according to common characteristics. A computer system and method for maintaining a central database of preferred addresses is also disclosed. Selected address data gathered in a queue may be scored by characteristic, grouped by consignee location, and staged for processing. The scored queue of data may be prioritized by clustering like characteristics, building similarity matrices, and by constructing dendrograms.
