An electronic flow meter having sensors to determine the temperature and flow rate of a fluid flowing through the flow meter and into a downstream circuit, such as a cooling water circuit, of known diameter is flowing under turbulent or laminar conditions based upon a calculation of a corresponding Reynolds number and comparison of the calculated Reynolds number to Reynolds numbers indicative of the desired flow characteristic. A display is provided to indicate the flow characteristic of the fluid flowing through the flow meter as determined by the processor.

A flow meter having a scale with temperature set points corresponding to a flow rate that a known fluid flowing therethrough at the set point temperature must reach to ensure turbulent flow of the fluid through a cooling system of a specified diameter. The flow meter preferably includes a plurality of scales, each having temperature set points corresponding to a different sized passageway in the mold cooling system. The scales are printed on a sleeve, rotatably mounted on a cylindrical body of the flow meter. The scales are selectively rotated into view by an operator to permit the operator to use the appropriate scale corresponding to the diameter of the passageways of the cooling system with which the flow meter is to be used.

A rotary disc valve is disclosed which generally includes a housing having an inlet side and an outlet side, and a disc rotatably mounted within the housing between the inlet side and the outlet side thereof. The disc includes an outlet bore which is generally aligned with the axis of rotation of the disc and extends from the outlet face of the disc partially through the disc. One or more inlet bores spaced radially outwardly from the axis of rotation of the disc extend from the inlet face of the disc partially through the disc and communicate with the outlet bore. The inlet bore or bores are located such that a bore may be selectively brought into communication with a single one of inlet side passages by rotating the disc until the bore is aligned with the desired passage. Since the outlet bore and an outlet passage are aligned along the center of rotation of the disc, the outlet bore stays in constant communication with the outlet passage in the outlet side of the housing as the disc is rotated. Therefore, by rotating the disc until an inlet passage is aligned with a respective disc inlet bore, that inlet passage is brought into communication with the outlet passage, making it possible for a fluid to flow through the valve between the inlet and outlet sides.

A quick connect coupler for connection to a stud includes a female coupler body having a plurality of balls in ball receiving bores which are advanceable into a stud bore in the female coupler for engaging a stud upon advancement of the stud into the stud bore. The balls are held in engagement with the stud by a locking collar having an annular groove. The female coupler is disengaged from the stud by pressurized air acting against a plunger mounted within the stud bore and connected to the locking collar to drive the locking collar forward such that the annular groove is advanced into alignment with the ball receiving bores in the female coupler body. A blocking sleeve is mounted on a plunger shaft and biased forward to slide across the ball receiving bores as the stud is withdrawn to hold the balls out of the stud bore.

A length adjustable extension bar for connecting a mold ejector plate to a press ejector plate comprises a rotatable member threadingly secured on one end of a threaded stud. An opposite end of the threaded stud is connected to the press ejector plate and a distal end or head of the rotatable member is connected to the mold ejector plate. Rotation of the rotatable member relative to the threaded stud increases or decreases the overall length of the extension bar. A locking assembly comprising a locking sleeve biased by a spring into engagement with a locking nut is mounted on the extension bar to prevent adjustments in the length of the extension bar without first advancing the locking sleeve out of engagement with the locking nut. The locking sleeve is slidably mounted on the rotatable member shaft but is prevented from rotating relative to the shaft by a pin extending through the rotatable member shaft and aligned slots formed on opposite sides of the locking sleeve. The spring is positioned on the rotatable member shaft between the rotatable member head and the sleeve to bias the sleeve toward and into engagement with the locking nut.
