摘要:
An apparatus (20, 30) operative from a first liquid pressure only and configured to generate and selectively direct a stream of first liquid or a third liquid is disclosed. Since no electrical power is used, the apparatus can be safely operated in any moist environments (e.g. a shower). In preferred embodiments, the apparatus is configured to operate in series with a showerhead (22) and a sink tap (32) for dental irrigation. Either water or dental solution which is comprised of water mixed with dental concentrate, can be independently selected. A mixer valve (48) controls the concentration of the irrigating solution. A handheld syringe (40) contains all other controls necessary for operation.
摘要:
A media holder (20) is disclosed particularly suited for search and display of a selected media. The holder has a plurality of frames (22) each configured to hold media (e.g. business cards, compact discs, computer diskettes) and pivotally mounted over a slidable striking member (44). The striking member contacts an abutment member (50) defined by each frame to flip the frame for viewing.
摘要:
An apparatus (20, 60) capable of dispensing a liquid 1 (e.g. water) or a liquid 1/liquid 2 mixture through a hand held syringe (26) and configured, in embodiments thereof, to be attached to a showerhead (24) or sink faucet (68) is provided. Liquid 2 (e.g. a dental concentrate) is held in a container (140) and dispensed by liquid 1 pressure on a piston (142) therein. A spool valve (84) responsive to a liquid 1 pressure bleed line (110a, 110b) diverts liquid 1 from the showerhead or sink faucet to drive the piston. The apparatus is controlled by a mode control disc (30) mounted in the syringe. Provisions for adjusting the flow rate of the dispensed liquid (34) and the proportional mix of the liquid 1/liquid 2 mixture (160) are provided.
摘要:
An oral irrigating liquid dispenser (20) is disclosed which operates from a liquid pressure source (22) to dispense two liquids (54, 72) from an orifice (26). A valve member (24) moves to different positions to couple the source respectively to a piston face (64A), a conduit (60) and an outlet port (71). Flow control valves (80, 89) are provided to control flow from the orifice. Since no electrical power is involved the dispenser may safely be used in the presence of liquids and electrical grounds.
