Abstract: A trash bag caddy is disclosed herein having a rigid hoop and rod base therefore for supporting and holding the entrance of a trash bag open to receive leaves, trash, debris or the like. The bag is composed of pliable, resilient material adapted to be folded over the hoop. The rod base includes a pair of U-shaped leg members arranged normal to each other having their free ends detachably secured to the hoop by snap-lock fasteners. A circular snap-lock fastener detachably secures overlapping portions of the leg members together to maintain the leg members substantially at right angles to each other.

Abstract: A pulsating device is disclosed herein for interrupting the flow of water being discharged via a nozzle carried on a dental syringe. The device includes a body coupled between the syringe and the nozzle having a central cavity partially occupied by a flutter valve. The valve includes a broad, flat member pivotally carried at its mid-section in the cavity so as to interfere with a flow of water passing through the cavity from the syringe to the nozzle. One end of the member is weighted so that the member flutters across the ports of the syringe and the nozzle to interrupt the water flow in response to the incoming water pressure from the syringe.
