Abstract: A fountain (50) comprises a supply of water under pressure, a primary fluidic diverter (10) having an input (12) for said supply, and first and second outputs (16a, b) diverging from said input. Two control ports (20a, b) are provided with control flow to direct input flow to one or other of the two outputs that lead to the two inputs of a vortex amplifier (40). This comprises a vortex chamber (54), a radial port (50), a vortex inducing port (60) and an axial output port (58). One (16a) of the diverter outputs is connected to the vortex inducing port, the other (16b) to the radial port, so that supply to said axial output port is modulated by formation of a vortex in the chamber when flow is to the vortex inducing port. The axial port leads to a nozzle whereby a vortex spray or axial jet is produced, depending on which diverter output (16a, b) is active. A wind detector (100) has a vertical jet (102) and a catcher (104) which fails to catch water from the jet in high wind conditions.

Abstract: A tap (1) is disclosed for dispensing liquids from a vessel, composed of: a body (3) made in a single piece comprising: a supporting member (5) from which a liquid dispensing mouth (7) and air entering mouths (9) project; a resilient thrusting member (11) that allows/prevents the dispensing of liquids; and winged abutting means (12); and a valve member (14) contained inside the body (3) and adapted to engage at one end the outlet mouth of the vessel in order to open/close it, and adapted to further engage the resilient member (11) to open and close the liquid dispensing opening.

Abstract: A holder for a disk having a central opening includes a base, a forwardly projecting ring for supporting the disk, a diaphragm supported within the ring member, and a button structure projecting forwardly from the diaphragm for engaging the central opening. Retainer members project radially outwardly from the central opening proximate the front face surface for releasably holding the disk when the diaphragm member is in a relaxed position. Downward pressure on the button structure deflects the diaphragm to move the retainer members inwardly for releasing the disk. The retainer members are on hook stem members that are rigidly joined to an inner extremity of the diaphragm in radial alignment with circumferentially spaced ring attachment locations of the diaphragm. Button stem members rigidly connect a button member to the diaphragm in alternating circumferentially spaced relation to the hook stem members to provide greatly enhanced lateral support of the disk.

Abstract: A holder for a disk having a central opening and front and back surfaces includes a base having a planar panel and a forwardly projecting pedestal including a ring for supporting the disk, an inwardly extending disk member, a plurality of stem members for engaging the disk opening, and a corresponding plurality of U-shaped connector segments supporting the stem members in cantilevered relation to the disk member. Alternating ones of the stem members have outwardly projecting retainer members and inwardly projecting tab members, collectively forming a button surface for receiving downward pressure whereby the disk is releasable. Deformation of the pedestal in response to the downward pressure is concentrated in the connector segments and, to a limited extent, an innermost portion of the disk member, providing improved structural integrity for a given downward force required to release the disk.
