A display is provided to indicate the flow characteristic of the fluid flowing through the flow meter as determined by the processor.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A fail-safe lighting system which includes provision for setting priorities or sequences of operation for different lights or sets of lights. When normal power is interrupted, all or a selected number of lights remain lit and/or are dimmed, thus providing a first level of illumination during a predetermined period of time. However, when a selected interval of time has elapsed and the level of charge remaining on the battery or batteries which supply power during the interruption decreases, preselected one or ones of the lights are progressively dimmed or disconnected from the battery acccording to a predetermined schedule. Thus, the time during which one or more extremely critical lights remain lit can be substantially extended without depleting the charge on the battery.

Abstract: An improved method and apparatus for making solder connections from input/output connecting pins to the circuitry on a pinned metallized ceramic substrate. A solder preform in the shape of a sphere provides the correct volume of solder. These spheres are held in position at each desired joint by a templet. The substrate, solder sphere and templet assembly is passed through a furnace in a reducing atmosphere and at a temperature to facilitate solder reflow and wetting, thus creating a sound mechanical and electrical connection between the pin and its portion of the circuitry. The method and apparatus of the invention provides joints have a high degree of reliability such that all connections are made to acceptable soldering standards, none lacking integrity. Only harmless by-products are produced in the practice of the invention, and no residue is produced which requires cleaning by means of chemical solvents and therefore is environmentally superior.

Abstract: Air blast peening equipment includes a flow density transducer and a pressure or velocity transducer for measuring flow velocity. Measured values are compared during peening with predetermined desired values. Operation of the apparatus is automatically adjusted, if necessary, by adjustment of flow density and/or flow velocity to maintain these parameters at desired values.

Abstract: A wellhead assembly especially suited for oil wells has a wide working pressure range and employs three components which fit together to seal the well casing, hold the tubing against high wellhead pressures, and provide a connection to the tubing through which the sucker rods are operated. The primary casing seal is formed by the mating contact of metal surfaces that are not subject to deterioration. The actuator for the subsurface pump is a vertically disposed hydraulic cylinder unit aligned with the sucker rods and forming the uppermost section of an elongated cylindrical housing, which also has a lowermost section on the wellhead that provides the outlets for the fluid pumped from the well, and an intermediate, control section that contains a spool valve for controlling the hydraulic actuator. The spool is shifted by the piston and rod of the hydraulic actuator at the upper and lower limits of their stroke to thereby reciprocate the sucker rods and operate the subsurface pump.
