Title: Improvements in or relating to apparatus for producing liquid pulsations through screens
IPC: D21D5/04
Filed: 1936-08-20
Abstract: 485,553. Strainers. OESCH, E. G. Aug. 20, 1936, Nos. 22930/36 and 11386/37. [Class 46] In apparatus of the kind used in the paper industry for the screening of pulp and comprising a set of screen plates mounted in series in a slightly inclined plate over which the pulp flows to separate the fine particles or fibres from the coarse, a chamber is provided beneath each screen plate and, to assist the separation and prevent clogging of the slots, the liquid in the chambers is caused to pulsate by means of fluid pressure acting either on flexible diaphragms forming the bottoms of the chambers, on auxiliary diaphragms connected to the said diaphragms, or, in the case of hydraulic pressure, directly on the liquid in the chambers. The fluid pressure is delivered in the desired sequence to the screen sections by a distributing device connected to the source of fluid pressure and rotating in a casing having ports leading to the individual sections of groups of sections. Fig. 1 shows a screen made up of a series of screen plates e<1> ... e<7> mounted over chambers b<1> ... b<7> in which pulsations are produced by fluid pressure, the pressure being distributed in sequence to the group b<1>, b<4>, b<7>, to the group b<2>, b<5>, and the group b<3>, b<6>. The distribution is effected by a member 5 which is connected to an external source of fluid pressure or may, as shown in Fig. 2, be mounted in a body comprising a pump 1, the member 5 being connected to the outlet 4 of the pump. The member 5 rotates in a casing 7 having ports a, a<2>, a<1>, leading to the groups of screen sections. In the chamber b<7> the pressure acts directly on the liquid in the chamber, the distributing pipe terminating in a diffuser h<7>. In the chambers b<4>, b<5> and b<6> it acts on diaphragms forming the bottoms of the chambers, and in the chambers b<1>, b<2> and b<3> it acts on auxiliary diaphragms c<1>, c<2>, c<3> mounted in chambers d<1>, d<2>, d<3> and connected by stems f<1>, f<2>, f<3>, to the diaphragms forming the bottoms of the chambers b<1>, b<2>, b<3>. Each of the diaphragms on which the fluid acts is maintained in equilibrium by opposing springs, for example g<1> and h<1>, which may be tuned so that the frequency of oscillation of the diaphragms corresponds to the frequency of the pulsations. After the pressure pulse, the fluid flows back into the casing 7 and through the passage 8 either to discharge or to the inlet of the pump 1. If desired separate pipes may be used for conveying the pressure fluid to the chambers and discharging it therefrom.

Abstract: 951,691. Fluid-pressure apparatus. SPERRY RAND CORPORATION. June 26, 1961 [June 27, 1960], No. 22949/61. Heading F1P. [Also in Divisions F2 and G3] A bank of manually-operable spool-valves is made up of an inlet section 10, an intermediate section 12, and an outlet section 14, each section housing a manually-operable spool-closure 23, 35, 37, respectively. Any number of intermediate sections 12 may be used or the bank may comprise only inlet and outlet sections. Each closure controls a pair of working ports leading to a motor but one of the two ports in the outlet section 14 is blanked off. A supply port is provided in the inlet sections 12, which port opens into a passage 54 in series with passages 56, 58 in the other two sections, respectively, each of which passages is intersected by a check-valve bore 60, 61 or 62 that is connected by the associated valve, not shown, to a corresponding pressure port 64, 66 or 68 for the related spool-closure bore. Each of the latter also incorporates pairs of motor ports 70, 72, and pairs of return ports 74, 76. The return ports lead through series passages 78, 80 in the upper and lower parts of each section to a common port 82 in the outlet section. Each spool bore has a spool controlled by-pass passage 84, 86, the passages in the various section being arranged in series between the supply port and port 82. The spools are each urged to the neutral position shown by a spring 99 between retainers 101, 103 in which position the motor ports are closed and the supply is by-passed to the port 82 or to a separate external port 128. A main relief-valve is provided to ensure a regulated flow rate through the by-pass passages 84, 86 only when all the spools are in the neutral position, which valve is disposed in the inlet section 10, Fig. 2, and consists of a main spring- loaded valve 102 in which is seated a pilot valve 104, the upper and lower faces of the main valve being subjected to supply pressure upstream and downstream, respectively, of a throttle 110, the latter path also including a restriction 114. The main valve 102 controls the connection of the supply passage 54 to an isolated exhaust passage 124 which meets similar passages in the intermediate and outlet sections. - When the supply pressure attains a given level it unseats the pilot valve 104 to open the space beneath the main valve to the passage 124, whereupon the main valve opens. An hydraulic piston-and-cylinder device may be connected across ports 82 and 128 through a four way valve, the speed of the piston of which device is determined by the flow through the by-pass passages which is regulated by adjustment of the quantity of fluid exhausted through the main relief valve, which in turn depends upon the setting of the throttle 110 and the relief-valve spring. Specification 517,877 and U.S.A. Specification 2,289,567 are referred to.
