Title: Improvements in or relating to the Automatic Control of Piston-type Hydraulic Actuators
Inventor: MATHEWS ROBERT BARRY
IPC: G05D16/18
Filed: 1965-12-03
Abstract: 1,160,958. Jet propulsion nozzles. PLESSEY CO. Ltd. Nov. 28, 1966 [Dec. 3, 1965], No.51405/65. Heading F1J. [Also in Division G3] A hydraulic actuator for use with a fixed displacement pump 15 comprises a differential piston 18 with its smaller area side 23 permanently connected to the delivery side of the pump, a sensoractuated ram control valve 25 selectively to connect the larger area side 27 of the piston 18 to the pump delivery line 21 or to a spill outlet 17, a further spill outlet 37 from the pump delivery line provided with a pump load control valve 34 urged by a spring 36 to a closed position, and fluidpressure means 26, 29, 35 communicating with the side 27 of the piston to urge the valve 34 to an open position. In the preferred embodiment, the piston 18 operates the nozzle flaps of a gas turbine jet engine while the valve 25 is connected to a sensor 12 responding to the ratio of outlet to inlet pressures of the turbine. When the ratio increases and the flaps have to be closed, the valve 25 is moved to the left to connect the side 27 to a return line 17 and to permit the piston 18 to be moved by pump delivery pressure acting on the side 23. During operation of the ram, a relief valve 22 determines the delivery pressure while the valve 34 permits the pump to operate at a lower pressure when the ram is stationary and holds the flap in its set position. The aerodynamic reaction of the flap to the flow in the jet produces a force on the piston 18 and a fluid pressure in the duct 35 to move the valve 34 to a position in which flow into the spill passage 37 maintains the system in equilibrium. This spill passage is closed by a land 40 on the spool 25 when both sides of the piston are connected to the delivery line 21. A delayed ram response is thus avoided when the system has been in equilibrium at a low delivery pressure. When the after burners are out of action, the piston 18 opens and valve 41 to keep the pump delivery pressure at its minimum value.

A motor car 11 moving to the right on a conveyer, Fig. 1, and Fig. 2 (not shown), has its wheels cleaned by electrically rotated brush assemblies 27 comprising upper and lower relatively inclined brushes connected by universal joints or other connections (Figs. 4, 5, not shown). The brush assemblies which may be moved towards or away from the car by a piston and cylinder are mounted on air motordriven carriages 24 movable along rails 25, Fig. 4 (not shown), the electric power and fluid service lines 28-32 being flexibly connected to the carriages by lines 33, Figs. 2, 3 (not shown). In operation the wheels 12 move against and energize pusher arms 34 to initiate the washing operation and the brushes 27 are moved to contact the wheels. The carriages 24 are then moved along the rails 25 until cams 36 are operated to stop the washing and withdraw the brush assemblies. The carriages 24 are then returned at relatively high speed until cams 37 reduce their return speed and stopping cams 38 are reached. The cams 37 return the arms 34 to a position where they may be engaged by the car's rear wheels for a further operation.

Abstract: 1294446 Distributing fibres, lap forming MOTALA VERKSTAD AB 22 Oct 1969 [22 Oct 1968] 51686/69 Heading DIN [Also in Division B8] A main stream of particles, e.g. lead shot wood chips or fibres, is subdivided by being formed into a tubular stream on passing axially through a chamber 15 which contains a rotating fluid, e.g. air or liquid, and then being divided into a plurality of secondary streams in outlets 20. These outlets are separated from each other by a plurality of walls 17. The chamber 15 is cylindrical or has a plurality of coaxial cylindrical portions of different radii. As shown, the particles pass through the chamber 15 under the influence of a gravitational or magnetic field. The particles may be carried in the fluid medium to the chamber. The fluid is rotated by vanes 40, 41 or by introducing the fluid into the chamber tangentially. The lower portion of the chamber 15 can have studs on its walls, or can contain a contrarotating central portion 29 to cause turbulence and stop the rotational flow of the particles and allow them to settle uniformly through outlets 20. The particles can be introduced into the chamber at one point, or from a number of points. The fluid may flow through the chamber 15 in a direction opposite to that of the particles. The outlets 20 can feed the fibres through chutes onto spiked rolls which feed them onto a conveyor so as to form a fibre layer thereon. This fibre layer can be hot pressed to form a board.
