Abstract: A dispenser cap comprising an axially moveable collar that surrounds an inner unit, the inner unit comprising a mounting ring at its bottom that is suitable for placement on a container, a cylindrical wall having a section that defines a radial outlet hole, said radial outlet hole being located towards the upper end of the inner unit, and a release trigger at the upper end of the inner unit, said collar being moveable between a raised position in which it covers the radial outlet hole and a lowered position in which it does not cover the radial outlet hole, the axially moveable collar comprising an internal structure that blocks the depression of the release trigger when the collar is in its raised position.

Abstract: A wind driven sailing craft is disclosed with a hydrofoil element which provides variable lift to the stern of the craft to maintain a level trim when the craft is operated under power propulsion. The hydrofoil element includes a hydrofoil wing which rotates on a transverse axis to provide the desired lift.

Abstract: A wind driven sailing craft with a hull of the displacement type with a keel or keels, is provided with hydrofoil means adapted to lift the stern of the craft when the craft is propelled forwards in use by power propulsion means acting at the stern of the hull.

Abstract: In the present invention, an actuating mechanism for a hand held canister is provided in which a slider is moveable by finger pressure from a valve-disengaged position into a valve-engagable position and a concealed spring returns the slider to a valve-disengaged position when finger pressure is removed. The spring is preferably molded with the slider, projects through a slit in the over-cap of the canister and acts in a vertical plane against a stop depending from the over-cap. It is energised when the slider is moved into the valve engagable position. The slider is preferably releasably locked in the valve disengaged position.

Abstract: Hand held aerosol canisters can be accidentally discharged if the valve remains open after hand pressure is removed.
