Title: Improvements in or relating to fluid pressure systems
IPC: F15B17/00
Filed: 1945-05-29
Abstract: 615,313. Fluid-pressure servomotor-control systems. GROVES, M. V. May 29, 1945, No. 13452. Convention date, June 17, 1943. [Class 135] . [Also in Group XXXIV] Hydraulic power means for moving a member in " follow-up " response to the movement of a control lever is arranged to give " feel to the operator. Figs. 4, 5 show a two-way actuator for operating, for example, an aircraft rudder or elevator 176. The control lever 172 is connected by a link 170 to a cross-head 159 joined by screwed rods 157, 158 to a cross-head 153, so that on operation of the lever 172 the cross-heads 153, 159 and the interposed piston and valve assembly move relatively to a cylinder 115 which is secured to stationary lugs 118, 119..If the lever 172 is moved to move the piston 138<1> to the left, the pressure generated in the space 140<1> passes through ports 1491 to the booster cylinder 128 and closes the ring valve 145<1> to shut off the exhaust passages 146<1>, 147, 114, 136, 134. The valve 151<1> during the first stage of movement of the lever 172 is closed to isolate the pump pressure which is admitted through the port 162 to the space 163. The movement of the piston 138<1> relatively to the piston 122 brings a valve 152<1>, acting in this connection as a stop, into action to open the valve 151<1>, thus admitting the pump fluid to the chambers 1401, 128 and giving " feel " to the operator. The piston 122 then follows up " the piston 1381 until the valve 151<1> again closes, the booster pressure on the piston 122 being transmitted to a cap 130 for the hollow pistonrod 136, bifurcations 131, 132 on the cap being pivoted at 133 to the link 174. The valve 152<1> closes if the booster pressure fails, to permit the apparatus to be operated manually by the differential hydraulic action of the pistons 1381, 122, or ultimately by the direct mechanical contact between the pistons. When the handle 172 is moved to move the piston 138<1> to the right, the valve 151 closes and a shoulder on the piston opens the valve 1451 to connect the space 128 with the exhaust system leading to the reservoir 179. The piston 138, being secured to the cross-head 153, also moves to the right, and produces a compound hydraulic manual operation of the piston 122, followed by a booster-operated movement of the piston 122, in the same manner, but in the opposite direction, as that produced by the leftward movement of the piston 1381. In a modification, the stop or valve 152<1> is modified so that the initial movement of the piston 122, produced by manual effort alone, is in two stages, viz. a stage in which the piston 1381 and 122 move as one because of fluid trapped between them, and a stage in which, due to increase in fluid pressure, a valve is opened to permit the trapped fluid to pass to the booster chamber, after which the power pressure comes into action as before.

Abstract: 750,666. Cleaning heat-exchangers. AKTIEBOLAGET A. EKSTROMS MASKINAFFAR. May 7, 1954 [May 15, 1953], No. 13461/54. Class 99(2). In a heat-exchanger wherein the gas-swept heating surfaces thereof are cleaned by elements of relatively high specific weight, e.g. steel shot, which are allowed to fall onto the surfaces, a part part of the flue gases is injected into the bottom of the exchanger to set an upward stream which separates particles of dust and ashes from the shot and carries those particles to the flue gas outlet to be carried off by the gas flow out of the exchanger.' As shown, the lower part 10 of the heat-exchanger terminates in a funnel-shaped pocket in which the shot previously passed through the exchanger is collected, the lower end of the pocket being connected by a duct 12 to a separator 13 serving to separate greater accumulations of dust from the shot, and the outlet of which opens into a conveyor duct 14 by which the shot is returned to the top of the exchanger, separated from the air or other gas which transports the shot, and again distributed over the heating surfaces. A gas outlet 15 is connected to a conduit 16 provided with filters 17. Downstream of the filters 17 a duct 18 branches from the conduit 16 so that flue gas is delivered via a choke and shut-off valve 21, by a fan 19 to a duct 20 connected to the pocket 11 and by branch conduits 22 to corresponding ducts in other heat-exchangers served by the same fan and gas conduit 16 ; alternatively, the duct 20 is in communication with the pressure side of the flue gas fan of a boiler so that the fan 19 may be dispensed with. At one side of the pocket 11 is provided a screen 23 and a screen 24 forms a narrow slit 25, which may be adjusted in width, with the wall of the pocket, Flue gas from the duct 20 passes through the slit 25 to meet the falling shot and carry the dust accompanying the shot into the gas stream deflected by a screen 26 into the conduit 16 wherein the particles are trapped by the filters 17, the shot passing through the slit 25 and into the duct 12.
