An orifice assembly for use in sealed fluid connection between a gas inlet and gas outlet in a gas flow meter includes a rotor positioned for rotatable movement in fluid connection with both the gas inlet and gas outlet. The rotor includes a plurality of bores in a first circular plate and a matching number of gas passageways in a second circular plate, the passageways being aligned with the bores. The rotor also includes an annular groove separating the first and second circular plates and in fluid communication with the gas inlet for introducing gas into the gas passageways. A plug is adjustably positioned in each bore and axially movable toward the corresponding gas passageway to partially block gas flow from the inlet toward the outlet.

Orifice assembly for gas metering device

An improvement in the orifice assembly of a high pressure gas flow meter configures the orifice assembly with a plurality of brass disks arranged in a circular array with orifices of different diameters through the brass disks to provide a variety of gas flow rates through the orifice assembly. Each disk is held in position by an O-ring disposed between the disks and a retaining plate fixed to the rotor.

Described briefly, according to a typical embodiment of the invention, a roller has a core comprising plurality of relatively hard and rigid segments fastened together in a stack and rotatably mounted to a shaft. The roller core has internal baffled passageways established by grooves in abutting faces of segments, so that, when paint is supplied to a cavity in the center of the stack, it will depart through these passageways in the roller in a controlled manner. A replaceable sock-like cover is received on the roller stack and secured by end retainers. The roller can be easily and completely disassembled for cleaning.

Painting roller assembly

A paint roller is provided with a removable sleeve receiving a cover having a pile on a stretchable flexible backing. A reversible, speed controllable pump on a hand cart provides paint to the roller from a supply under control of a switch at the roller handle. The roller handle contains a radio transmitter for transmission of pump control signals to a receiver in a pump housing mounted to the hand cart. A peristaltic pump is used for the pumping, and is reversible to facilitate draining of the system back to the paint source. Opening of a door on the pump housing releases pump roller pressure from pump tubing, provides access to pump rollers and pump tubing, and thereby facilitates installation and removal of the pump tubing. Conventional water hose fittings are provided to facilitate cleaning by connection to a hose bib of a domestic water system, if desired. The entire unit is conveniently transportable on a three-wheel cart and provided with a lamp for illuminating the work, and electric power supply for the pump. A spear type intake tube is available for puncturing a paint can and removing paint directly through a punctured lid thereof, without opening the can. The cart includes a well to receive a conventional five gallon paint can, and a well to receive the roller, which well may also be used to facilitate cleaning. There is a swivel coupling on the paint supply line to the roller feed line.
