Abstract: A powder sprayer having a housing for containing a quantity of powder, a rotatable roller for metering the discharge of powder from the housing, a powder supply hopper remote from the housing, first and second conduits connecting the powder supply and housing, and a selectively operable regenerative type blower disposed in one of the conduits. The first and second conduits, blower, housing, and supply hopper define a closed loop through which air and powder may be circulated with relatively low-pressure, high air-flow operation for reliably transferring powder from the supply hopper to the housing without the tendency for clogging. In one embodiment, the supply hopper has an associated mixing chamber within which powder is pneumatically agitated for creating a relatively rich, substantially constant air-powder mixture for direction to the sprayer housing.

Abstract: This invention provides a modification kit by means of which a conventional toilet of the flush tank type may be converted into a dual flush system. The mechanism is mounted and secured inside a flush tank on the front wall of the tank and is operationally connected to the flushing lever and the water outlet valve. The invention incorporates a float which may be selectively controlled by the flushing handle on the outside of the tank to permit a vertical float type outlet valve or a flapper type outlet valve to close at a reduced or full flush of the toilet at the discretion of the user. In part this disclosure is an improvement on a previous invention described in full in my patent application Ser. No. 261,303 (Series of 1970).
