Abstract: A rotary valve rotated by an arm connected to a piston being driven by the pressurized fluid, either water or air. The orientation of the valve body in the valve housing will direct the fluid in one of two directions to move the piston. The arm of the rotary valve is connected to a cam that rotates a shaft connected to the valve body. Two cam rollers are biased towards the outer surface of the rotating cam member. The cam rollers provide a force to the cam to aid in the changing of the orientation of the valve body. There are two bump outs on the cam that correlate to the end of the piston movement so that the rotary valve does not stop at an end point of the piston stroke. The rotary valve may be is utilized in a chemical dosing or chemical application device that is driven by pressurized fluid.

Abstract: An improved fluid proportioner. For improved fluid flow, a body is configured to direct a first fluid wherein at least one fluid gate housing is removably fixed to the body. A bearing pressurably is fitted within the at least one fluid gate housing to seal the first fluid within the body. A fluid gate is disposed within the body configured to gate the first fluid to alternating sides of a motor cylinder having a motor piston sealably disposed within. The motor piston has a cap attached at an end wherein the cap has a concave annular groove. A seal is surroundably disposed around the concave annular groove which radially extends beyond the cap to pressurably engage against the motor cylinder to reduce friction. A slave pump has a inlet valve and a outlet valve with an inlet raised base formed around an inlet orifice and an outlet raised base formed around an outlet orifice.

Abstract: Telescopic stands for articles such as microphones used by entertainers, hospital intravenous packets and cameras are widely used. Some telescoping microphone and hospital intravenous stands require many turns of a ring in order to hold the microphone, for instance, in place. An entertainer needs to be able to almost instantly adjust the height of his microphone. The stand herein includes a height adjusting means which operates more quickly. It includes telescopically related outer and inner members, and also means for readily locking the upper inner member within the lower outer member.

Abstract: The present invention provides a self-powered proportioner which can automatically, proportionally mix two fluids in a low ratio. A fluid gating means is disposed intermediate a fluid supply and a motor piston to cause reciprocating movement of the motor piston within a motor cylinder. A connecting rod secured to the motor piston is disposed within a cavity in the housing extending between the motor cylinder and a slave pump cylinder. A slave pump piston is secured to the connecting rod for providing responsive reciprocatory movement of the slave pump piston within slave pump cylinder for pumping a second fluid. A connecting rod seal is interposed between the cavity wall and the connecting rod intermediate the motor cylinder and the slave pump cylinder preventing fluid communication through the cavity between the motor cylinder and the slave pump cylinder.

Abstract: An improved variable proportioner is provided which includes a spring biased lost motion connection between the motor piston and the slave pump piston thus providing for accurate adjustability of the metering proportion as well as prevention of stalling of the slave piston against the front cylinder wall. A pivotable connection of the toggle lever spring is also provided to reduce bending of the spring and to enhance its life span.
