Title: Improvements relating to Gas-Cushion Vehicles.
Inventor: CLARKE PETER JOHN
IPC: B60V1/16
Filed: 1966-03-30
Abstract: 1,179,121. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. 15 March, 1967 [30 March, 1966], No.14131/66. Heading B7K. In an air cushion vehicle formed at its forward end with a flexible skirt 16, a flexible inflatable chamber 23 is positioned between hard structure 24 and skirt 16. The chamber is supplied with pressure air from a duct 9 and manifold 10, the air being discharged through apertures 29 to form and maintain the cushion 3. Upon deflection of skirt 16 by waves, which would cause a loss of cushion air with consequent forward pitching, the skirt seals apertures 29 whereby chamber 23 experiences a rise in pressure and thereby reacts on the skirt to restore it to its original position. In an alternative arrangement (Fig. 5, not shown) the chamber is sealed and permanently inflated and secured to the inner wall of the skirt and in another embodiment (Fig. 6, not shown) a chamber secured to the hard structure is sealed and inflated separately from the supply of cushion air. The skirt may comprise a plurality of elements such as described in Specification 1,043,351 each provided with an inflatable chamber. ,

Patent GB-718374-A (GB)
Title: Manufacture of aqueous pigment pastes
Inventor: AMBLER ARNOLD EDWIN
IPC: C09C3/00
Filed: 1951-06-15
Abstract: A process for the manufacture of aqueous pigment pastes of high viscosity comprises adding a non-acidic substance which in the presence of water gives rise to an acid, to a fluid aqueous pigment paste which has been peptized by the addition of a soap. An aqueous pigment paste is peptized with 1 per cent. or more of a soap such as sodium stearate or sodium oleate, to form a fluid pigment paste which is standardized to the required strength and shade.  A non-acidic substance which forms an acid with water such as phthalic or maleic anhydride, is dispersed in water and added immediately to the pigment paste.  The acid formed decomposes the soap and causes the paste to flocculate to give a thick viscous paste, suitable for use in flushing processes.  The pigments may be inorganic or organic, e.g. azo or phthalocyanine pigments. Specification 13422/13, [Class 95], is referred to.

Abstract: 641,604. Helicopters. UNITED HELICOPTERS, Inc. June 5, 1947, No. 14906. Convention date, Aug. 12, 1946. [Class 4] A helicopter with coaxial contra-rotating blade systems is provided with a linkage for moving the pitch control members simultaneously in either direction to impart equal and opposite pitch variations to the rotors for yaw control, and a further linkage for superimposing on one of the rotors a pitch change of twice the magnitude and opposite sign to that imparted by the movement of the pitch control member, to vary the total lift exerted. General construction.-The invention is shown applied to a helicopter with coaxial contradriven rotors 26, 27 with blades of the non- articulated variable-pitch type. Pitch variation is effected by gimbal mechanisms 91, 101 connected by a sleeve 57 and operating the respective pitch control arms 72 through links 113, 114 and 116, 122. The rotor shafts 52, 53 are driven from the engine shaft 14 through a universal coupling 31, a drive shaft 32 and sleeve 33 engaged by a clutch 21, spur pinions 36, 37 and bevel pinions 41, 42, 43. Cyclic pitch control.-The pairs of gimbal rings are tilted for directional control purposes' by links 133 pivoted to depending arms 131 and actuated by threaded members 136, each moved axially by a cable 141 connected to the pilot's control column and passing around a sleeve 137 carrying the member 136. Differential collective pitch control.-The aircraft is controlled in yaw by rudder pedals connected by a cable 151 to a pulley 152, Fig. 2, actuating the gimbal rings through an arm 154 and links 156, 82. The rings are moved in the same axial direction to impart equal and opposite pitch changes to the respective rotors. Simultaneous collective pitch control.-Vertical movement of the aircraft is controlled by a hand lever connected by a cable to a pulley 161, Fig. 2, the latter operating the gimbal rings to impose equal and opposite pitch changes to the rotors. The pulley 161 is also connected, through links 164, 166 to an axial rod 121 extending through the rotor drive shafts and attached at its upper end to a spider 118 connected to the pitch control arms of the upper rotor blades, the linkage being so arranged that the rod 121 superimposes on the upper rotor blades a pitch change of twice the magnitude and of opposite sign to that imparted by the axial displacement of the gimbal rings, thus resulting in pitch variations of equal magnitude and of the same sign being applied to the respective rotors. Specification 623,470 is referred to.
