Abstract: The disclosed fiberglass cutting device with yoke-supported adjustable roller is a device, or “gun,” with on-the-fly—during operation adjustment of the spacing between the anvil roller and cutter. This adjustability is accomplished using only a single tension-adjusting knob located to one side of the anvil roller. This is superior to the prior art that required, at a minimum, two tension-adjusting knobs—one for each side of the anvil roller. To solve this problem, the fiberglass cutting device with yoke-supported adjustable roller supports the supports the anvil roller on both ends using a yoke. The position of the yoke is controlled by a single tension-adjustment knob that moves both arms of the yoke, thus maintaining the anvil roller in a position parallel to the cutting roller. The use of the yoke also avoids only supporting the anvil roller at a single end, which creates an unstable cantilevered-roller.

Abstract: The frame-supported pump is assembled without the use of tools. In place of bolts or threaded connections, an external frame provides the support necessary to resist the internal pressure of the pump. Upper and lower pump housings include grooves that slide into a slotted support or frame—a slip-in mount. In alternative embodiments the grooves are replaced with holes that slide over rods, or other means of external support prevent the pump housings from moving away from each other during pumping. A pin is optionally used to prevent the housings from sliding out of the frame, or friction is sufficient. When the pumps are in service, the internal pressure attempts to push the housings away from each other, but this force is passed to the frame, which responds with a matching force, keeping the housings in place.

Abstract: A flow alarm includes a magnetic switch that is maintained open so long as catalyst flow is maintained and an air flow switch that is closed responsive to flow of air through an associated conduit. The associated conduit supplies air via a solenoid valve to a pneumatic whistle. When flow of catalyst falls below a pre-set threshhold, the magnetic switch closes completing the circuit with the solenoid valve causing the solenoid valve to open and allowing air flow to the pneumatic whistle to signal the reduction of catalyst flow.
