Abstract: An actuation mechanism used in, for example, a missile assembly is disclosed, as are methods of its use. The actuation mechanism is locked in a first orientation and is unlocked in a second orientation. Locking and unlocking of the actuation mechanism is achieved by way of a locking mechanism that responds to a certain stimulus. In some embodiments, the actuation mechanism is incorporated into a sub-assembly of a missile to assist in controlling the missile's flight.

Abstract: A pressure-regulating valve particularly useful in a diesel internal combustion engine with a closed crankcase is provided. The valve includes a body coupled to a bonnet with an internal movable piston. The movable piston maintains a substantially constant pressure in the crankcase by adjusting a fluid flow in response to changes in pressure. The movable piston also includes an integral relief valve to prevent overpressure in the event of a crankcase pressure in excess of the designed limits of the pressure-regulating valve.

Abstract: A Drill Bit detector for use with numerically controlled drilling machine capable of sensing missing or broken Drill Bits in the range of 1 mil to 30 mils in diameter, or larger, is described. An infrared emitting diode is driven at a predetermined frequency with the pulsed light being directed through fiber optic cable directed at a portion of the Drill Bit to be detected. A change of light intensity occurring when a Drill Bit is missing is detected and the pulsed light detected converted to a pulsating electrical signal at the input frequency of the pulse light source. A frequency responsive circuit converts the pulsating electrical circuit to a digital signal indicative of the absence of the sensed Drill Bit. A timer determines whether or not the sensed digital signal occurs for a predetermined threshold time period, and causes it to be ignored as spurious if less than the predetermined time interval, or causes the drilling machine operation to be halted if occurring longer than the threshold time period.
