Title: Closure-assisted cartridge- type flow control valve
Inventor: BOTNICK IRLIN HOWARD
IPC: E03C1/04
Filed: 1985-05-20
Abstract: A closure-assisted valve includes a cartridge insertable into, and removable from, the remainder of the valve structure. The cartridge includes a displaceable piston 104, 204 having a sealing member 120, 344, at one end engageable with a valve seat 249, 341. At the other end, the piston includes a drive surface against which a rotatable drive member is engaged. In a preferred embodiment, certain relatively movable portions of the cartridge include a cam surface and a cam follower. The cam surface is contoured such that the piston is advanced toward a valve closed position upon rotation of the drive member, but the last portion of piston travel prior to valve closure is only under the influence of gravity and fluid forces. In order to bias the piston toward a valve closed piston, entering fluid may be directed around the piston so as to aspirate the piston toward a closed position. Upwardly extending channels divert a portion of the incoming fluid upwardly around the piston and thereafter downwardly against a face of the piston spaced from the valve seat. The pressure of the fluid against the face assists in constantly urging the piston toward a valve closed position. <IMAGE>

Title: Hydrofoil steering mechanism
Inventor: HANDLEY MILES
IPC: B63H25/38
Filed: 1985-07-11
Abstract: Hydrofoils 1 have stub axes 3 which rotate in hubs 4 fixed to the stern of a boat 2, in an inverted V arrangement with the axes of rotation at an angle which preferably lies between 101 DEG  and 79 DEG . Each stub axle 3 is fitted with a crank arm 6 connected by a steering push rod 5 to a steering arm 7 pivoted at 9. The rods 5 are connected to the arm 7 by pivot joints 8 which are slightly offset to the rear of the pivot 9. Steering forces are applied to the arm 7 by cables or rods 10 controlled by a steering wheel, and movement of the steering arm 7 rotates the hydrofoils 1 in the same direction, so as to modify their angles of attack and creating an angle of attack differential between the two, thus inducing a steering force. The offset between the pivot points 8 and the pivot 9 renders the differential of the angle of attack non-linear so that each hydrofoil 1 describes the correct circle about a common centre of turn. <IMAGE>

Title: Unit for wet purification of gases
Inventor: KWASNIAK JAN
IPC: B01D50/00
Filed: 1986-01-22
Abstract: A unit for removing soluble contaminants, droplets and dust particles comprises at least one drum (3) rotatably mounted in a housing (1) such that the cylindrical wall of the drum (3) may be immersed in a liquid (10). The cylindrical wall of the drum (3) is porous and comprises layers of strips (4, 5) of involute shape and of equal scale. The curvature of the strips (4) and (5) belonging to adjacent layers is reversed. The drum (3) is rotated in use so that the strip surfaces thereof are continually wetted and washed by immersion in the liquid (10). Gas introduced to the unit for purification passes through the porous wall of the drum (3) in the form of a multiplicity of narrow streams crossing one another spatially. As a result of the receprocal transfer of momentum, said streams are caused to spin whilst moving along the flow passages, so that the centrifugal force acting on the particles separates them from the gas streams causing them to settle on the wetted surface of the strips (4, 5). <IMAGE>

Title: Improvements in video signals processing systems
Inventor: CAWLEY ROBIN ALEXANDER
IPC: G06T3/00
Filed: 1986-08-22
Abstract: A system for manipulating video images includes parallel transfer disc stores 7 which allow video signals to be stored and recalled at the usual video rate. Once the signals have been stored on the disc stores they are then transferred in real time to a framestore 4. When read out of the framestore for processing the signals are clocked at a slower rate. This allows the processing to be achieved in non-real time and so image processing costs may be reduced. The system described may produce images of different size, shape or orientation. <IMAGE>
