摘要： A system and method for controlling the temperature of the compresed fluid flowing through a compressor aftercooler. The system includes a compression module flow connected to an aftercooler and at least one repositionable fluid flow regulating member upstream from the aftercooler for modifying the volume of ambient fluid supplied across the aftercooler. The system further includes a temperature sensor for sensing the ambient temperature, and an actuator connected to the at least one fluid flow regulating member. A controller is in signal receiving relation with the temperature sensor and is in signal transmitting relation with the actuator. If the sensed ambient temperature is outside a predetermined range, a repositioning signal is sent by the controller to the actuator, extending or retracting the actuator the amount required to achieve the required fluid flow rate across the aftercooler and thereby maintain the desired aftercooler fluid discharge temperature for the ambient operating temperatures.

摘要： A method for measuring the machinability of a material includes piercing a hole through a material to be tested while simultaneously measuring a pierce time duration, T, of the piercing step, and calculating a machinability number from the pierce time duration. Also provided are methods for determining the machining speed of a material and for machining a material which calculate a machining speed for a material based upon the machinability number of the material. The methods used to measure the machinability number and calculate a machining speed for a particular material can include any combination of machining operations, including abrasive water jet cutting processes. Also provided is an apparatus which detects the time duration a piercing force takes to create a pierce-through condition through a material. The apparatus includes any of a pressure sensor, an acoustic sensor, an optical sensor, a load cell, a mechanical switch, or any combination thereof, to measure the pierce-time duration.

摘要： A rotational energy storage device (10) or spring which includes a roller-cam assembly having a shaft (14), a ring (12) rotatably disposed about the shaft, and at least one roller (16) disposed between shaft and ring. The roller (16) is configured such that, upon rotating the ring relative to the shaft, the roller interferes with the ring and the shaft to convert and effect storage of mechanical energy created by the relative rotation of the ring and the shaft. Preferably a plurality of spaced rollers are positioned between ring and shaft. A cam geometry (20) which is symmetrical or asymmetrical is provided on the shaft, the ring, the roller, and combinations thereof. A rotational energy storage device having a back-up ring with alternating thin and thick cross-sectional areas is further provided which is indexed to provide regions of low and high stiffness regions against each roller.

The valve member (22) is movable between a first position where a discrete toroidal mass of material to be dispensed is formed at the dispensing end (24) and a second position where a discrete toroidal mass of material to be dispensed is not formed at the dispensing end (24). The dispensing apparatus (10) also includes a material dispensing assembly comprising having a fluid knife for moving the discrete toroidal mass to be dispensed from the dispensing end (24) away from the dispensing end (24) when the valve member (22) is in the first position.
