摘要:
The present invention provides methods and systems for applying a coating to a non-ferrous or ferrous material that includes providing a material, a heat source, an immersion tank, and a drying environment. The material is placed within the heat source and heated to a temperature between the range of between about 204.44° C. to about 537.78° C. (400° F. to about 1000° F.). The material is immersed within an immersion containing a ratio of molybdenum disulfide solution to water of between about 2:1 to about 4:1 at a temperature between about 26.67° C. to about 48.89° C. (about 80° F. to 120° F.), and the material is dried at a temperature between about 51.67° C. to about 98.89° C. (125° F. and 210° F.).

A computerized method of monitoring and modifying student performance may include collecting student information from a plurality of sources, storing the information electronically in a retrievable form, and reviewing the student information for student issues, which may have a negative impact on performance of a student. If such student issues exist, communicating with a student regarding the same, creating an action plan to improve or terminate the student issues, and implementing the action plan. Time factors, the specific student issues, the student information, including prior history and collaboration of appropriate student advisors, are combined to establish and implement the action plan. This is followed by monitoring of the student of interest in respect of certain student issues, updating student information, and applying time factors related to individual issues in the monitoring of such subsequent student performance.

A method of producing panels from boards wherein a subassembly of boards is prepared on a conveyor and crowded against indexing pins. The trailing board in this subassembly is then cut lengthwise by a saw, to produce a panel assembly of predetermined width. Adhesive is then applied between contiguous edges of the boards in the panel assembly, and the boards then consolidated into an integral panel.

Saw mechanism including a power-rotated saw arbor. A shifter is mounted on the arbor at one location, and a saw collar is mounted on the arbor at another, spaced location. A shifter bar extends between the shifter and collar. A tapered element extending from the shifter seats within a corresponding tapered seat on one end of the shifter bar, and another tapered element extended from the collar seats within a correspondingly tapered seat on the opposite end of the shifter bar.

Some embodiments pertain to a projectile that includes a casing and a sensor that is wrapped around the casing. As an example, the sensor may be wrapped around a longitudinal axis of the casing. The sensor obtains environmental data that the projectile is exposed to when the projectile is inside a cannon tube. As an example, the sensor may obtain pressure data that the projectile is exposed to during launch of the projectile when the projectile is inside the cannon tube. The sensor may include a plurality of segments that at least partially surround the casing. In some embodiments, the segments may be separated from the casing due to pressure that the projectile is exposed to during launch.

摘要:
A rip saw with multiple saws adjustably positionable along a power-driven arbor. A clamp or hold-down assembly is provided on its upstream side, and on the downstream side, of the arbor and its saws. Each assembly is passable along an inclined path that converges on the path of travel of work through the machine. The assemblies inhibit fluttering in and otherwise stabilize boards as they are being cut by the saws.
摘要:
Arc discharge lamps driven at frequencies in excess of 20 kHz may exhibit the phenomenon of `acoustic resonance` in which longitudinal and lateral acoustic waves are supported in the arc tube. This is a problem because the acoustic wave may give rise to an instability in the discharge arc, causing it to stretch or gyrate and invariably to extinguish. In some cases damage may be caused to the arc tube. A power supply suitable for an arc discharge lamp comprises a drive circuit arranged to supply voltage to the lamp and control means for causing a characteristic of the voltage to vary, with time, in accordance with a pseudo random sequence in order to reduce, or eliminate, acoustic resonance in the lamp.
