A leak-stopping device for an hydraulic braking system includes spring - loaded pistons 3, 3a opera-. ting in slidably opposed relationship in a cylinder 1, an hydraulic inlet connection 6 leading from a master cylinder situated between the pistons 3, 3a, an hydraulic outlet 11 leading to different sets of brakes in the opposite side of each piston, and means 20, 22 being provided for by-passing the pistons for bleeding the system. In operation, when the hydraulic pressure is applied through the connection 6 the two pistons 3, 3a move away from each other and from inner stops 5 formed in the cylinder to transmit pressure to the connections 11 leading to the brake-applying cylinders. If one of these latter cylinders fails (e.g. that associated with piston 3, Fig. 6) the piston moves to the related end of the cylinder 1 against the pressure of it sreturn spring 4 but the system remains sealed by the piston blocking off the end port 9 leading to the faulty brake cylinder. Pressure is thus available at the other wheel-brake cylinders. When the system is required to be bled, the valve 22 is opened and one of the brake cylinder bleed nipples (not shown) is opened. Fluid can now enter from the main inlet 6 into the by-pass lines 20, 21 which also provides a path for fluid between the ports 9 by by-passing the pistons. One alternative embodiment is disclosed in the Specification wherein the respective pistons control bleed ports each leading to the outlet sides of the opposite piston. Another alternative embodiment (not shown) contemplates three or more brake cylinders adapted to be operated from a single safety cylinder which has one or more radiating arms each with its own control pistons.

Filed: 1973-09-05
Abstract: 1475074 Hydrofoil sailing craft J H PLESS 4 Sept 1974 [5 Sept 1973] 41789/73 Heading B7A A sailing vessel having one or more hulls 1, 2 and one or more masts 4 for carrying sails has at least one pair of opposing hydrofoils 7 mounted one at each side of the vessel. The hydrofoils are oppositely inclined as viewed along the length of the vessel and each is free to rotate about an axis between two limiting positions to alter its angle of attack. This axis of rotation is so located relative to the centre of pressure of the water which acts on the hydrofoil when the vessel is sailing and making leeway that both the hydrofoils are rotated automatically by the water pressure in such a way that the angles of attack of the hydrofoils are adjusted relative to each other to make the lift of the leeward hydrofoil greater than that of the windward one thus producing a force which acts against heeling of the vessel.
