Abstract: A partial flush apparatus, for use in conjunction with a conventional flush toilet, utilizes a pneumatic time delay mechanism for partially flushing the contents of the water tank into the toilet bowl. An extension member is secured to the conventional flush handle lever arm and a cable extends between the extension member and a plunger of the pneumatic time delay mechanism. When depressed, the plunger lifts the extension member and thereby partially opens a flapper valve at the bottom of the water tank for a predetermined time. The pneumatic time delay mechanism includes a spring for biasing the plunger to a released position after the plunger has been depressed. The plunger incoporates a one-way valve for facilitating movement of the plunger to the depressed position. The plunger also includes a longitudinal bore forming part of a fluid conducting path that controls the return of the plunger to the released position.

Abstract: Apparatus for treating bean sprouts to remove hulls, cut-off roots from the sprouts, and to wash them. The apparatus comprises essentially an open-top tank having a chute at one end for receiving sprouts to be cleaned, and a plurality of jets adjacent to the chute which delivers water thereto to agitate the sprouts. A source of water under pressure includes spray nozzles for filling the tank and further agitation. A conduit extends to a low pressure screen drum. From the latter, another conduit extends to a pump. A discharge chute communicates with the screen drum. Between the screen drum and the feed chute is a cylindrical screen which rotates in unison with the screen drum. A motor-driven drive belt rotates the screen drum and the cylindrical screen in unison. The cylindrical screen enhances the agitation and partially removes foreign material from the cylindrical member. The screen drum also has a plurality of radially extending blades which not only further the agitation, but also pick up foreign matter.

Abstract: A ball mill including the usual drum and a trommel screen rotatable therewith together with mechanism for returning damaged balls and large pieces of aggregate directly from the trommel screen to the drum. This mechanism comprises a plurality of blades mounted on the inner surface of the cylindrical screen which pick up material in the trommel screen as an incident to rotation thereof and dump it onto a trough which extends from the screen to the drum. A jet of water is introduced into the trough at its outer end and passes the materials back into the drum.

Abstract: A turquoise scrubber comprising a base and a casing upstanding from the base and having closed and open ends. A motor driven shaft extends through the casing centrally thereof and is journalled in supports upstanding from the base. A cylindrical screen is driveably mounted on the shaft and is spaced from the casing. A motor driven brush is swingably mounted on the base and extends into the screen. A discharge scoop is carried by a frame that is pivoted on the shaft and is located within the screen where it is adapted to be either spaced from the screen or have its leading edge in engagement therewith. Mechanism is provided to impart a limited arcuate movement to the scoop in reverse directions. A loading chute is positioned at the open face of the casing and includes a tube which extends into the screen. An exhaust conduit communicates with the closed end of the casing to withdraw fumes therefrom.
