Air and gas compressing and exhausting apparatus, applications of; direct air pressure apparatus, automatic.-In a system of raising liquids employing the static pressure between two liquid levels 1, 2, and having a number of closed containers or open and closed containers at successive heights above the level of the liquid to be raised, the closed containers communicating by air conduits with an operating chamber arranged at or near the surface of the low level liquid, or in a position between the two liquid levers,-two operating chambers A, A<1> at about the same level, and a single series or column of closed containers C - - C<4> or of open and closed containers are used, the closed containers being connected to the air conduits B, B<1> of the operating chambers A, A<1> in alternate manner, and means, such as a valve A<4>, being provided, operated by the working of the system for controlling the inlet and outlet of water to and from the chambers A, A<1> and causing them to operate alternately. The chambers C - - C<4> are superposed in the form of a column and are interconnected by pipes c<1> - - c<4> provided with valves or liquid seals and dipping into the liquid in the vessel. When the chamber A is filling and A<1> is discharging, pressure is produced in the pipe B and its connected chambers C<1>, C<3>, and suction is produced in the pipe B<1> and its connected chambers C, C<2>, so that water is forced from the chambers C<1>, C<3> through the pipes c<2>, c<4>, and is drawn into the chambers C, C<2> through the pipes c, c<2>. When the chamber A' is filling and A is discharging, the process in the pipes B, B<1> and chambers C - - C<4> is reversed. If the chambers A, A<1> are arranged at or near the surface of the low level water 2, the system works by pressure only. The valve A<4> may be operated in the manner described in Specification 217,654. According to the Provisional Specification, the system may be connected to atmosphere at the end of each pressure operation in the manner described in Specification 207,838.

Patent GB-340240-A (GB)
Title: Improvements in or relating to soot blowers
IPC: F28G3/16
Filed: 1929-09-18
Abstract: 340,240. Cleaning boilers. SMITH, W. A., Broadway Buildings, Westminster, and BABCOCK & WILCOX, Ltd., Babcock House, Farringdon Street, London. Sept. 18, 1929, No. 28323. [Class 99 (ii).] In a boiler cleaner of the kind in which air or steam is supplied in puffs at considerable intervals, the puffs are given a percussive effect by means of superimposed pulsations. Air is supplied from a compresser 1 and reservoir 2 to the rotating blower units 5 through a pressure-actuated valve 3 and a pulsating valve 10. The valve 3 opens at intervals according to the fluctuation of pressure in the reservoir, and the blowers are rotated by a compressed - air motor 4 supplied through a valve 6 which functions in synchronism with the valve 3. In non- effective positions of the blower units the valve 3 is closed by a cam 8 on the blower shaft. The valve 3 comprises a hollow piston 13, Fig. 2, which is raised by the air pressure against a spring 22 until ports 21 coincide with the passage 15 to the blower. A smaller piston valve 16 is connected to the valve 13, and the space above it communicates, when the valve 13 is closed, with the air supply through the pipe 17. As the valve is raised, the port 24 registers with the port 18, the pressure above the piston 16 is released, and the valve 13 moves quickly to full open position. A quickclosing movement is obtained when the supply pressure falls. The pulsating valve 10 comprises a double-skirted piston 26 having ports 38, 39 in the skirt 29. Compressed air supplied through the inlet 35 raises the piston against the action of the spring 34 and air is admitted to the blower head through the passage 28. When the port 38 registers with the port 30, air passes through the transfer passage 36 to the space above the piston until the pressure is equalized. The piston is then returned by the spring, closing the port 28, and pressure above the piston is released through port 39 and passage 31 so that the piston is again raised. The rate of pulsation is adjusted by a screw-valve 37. Specification 336,995, [Class 99 (ii), Pipes, tubes,&c.], is referred to.

Title: A valve for the automatic control of the supply of a fluid to a system
IPC: B03B5/24
Filed: 1950-11-21
Abstract: 722,993. Fluid-pressure servomotor-control systems ; fluid-actuated valves. AUTOMATIC COAL CLEANING CO., Ltd., and MENZIES, J. D. Nov. 21, 1950, No. 28474/50. Class 135. A valve for the automatic control of fluid supply to a system comprises two chambers a, d, one having a fluid inlet b and the other a fluid escape port, separated by a flexible diaphragm g, the position of which is determined by the pressure difference between the chambers and which diaphragm provides a seat h for a valve member j whose position is controlled by some condition in the system, one of the chambers having a delivery port to the system. The valve may control the supply of air to a coal washing installation for agitating water or to apparatus controlling the mixing of two liquids or solids. In the first case, the valve member has its spindle k connected to a float responsive to the amplitude of pulsation of the water, while in the second case the member is moved in response to variation in the supply of one of the constituents to be mixed. The inlet may have a manually-operated throttle, in which case the ports e, f are open to the atmosphere, so that as the valve j opens, the pressure at the delivery port c decreases and the diaphragm and seat follow up to a new position of equilibrium. The port c may be closed and the port e controlled by a manually-operated throttle so that as the valve j opens the pressure at the delivery port f now increases and again the diaphragm follows up to a new equilibrium position. When the valve j is stationary, the diaphragm flexes to maintain a constant air pressure at the port c.

Title: Differential pressure sensing device

Filed: 1972-06-19
Abstract: 1373597 Dual brake-line warning devices WEATHERHEAD CO 19 June 1972 [26 July 1971] 28510/72 Heading F2E In the pressure-sensitive switch device of Fig. 1 for providing an indication of loss of pressure in one or other of two chambers 12, 13, each connected to one line of a dual-circuit brake system, if pressure is lost in chamber 12 piston 16 moves leftwards and entrains sleeve 17. On repair of the fault giving rise to the pressure loss, and resumption of use, the pressure being restored in chamber 12 acts upon the crosssectional area of sleeve 17 and of the smallerdiameter part 51 of piston 16, while the pressure subsisting in chamber 13 acts upon the crosssectional area of part 46 of piston 16, which is slightly greater than that of part 51 but slightly less than the total cross-sectional area in chamber 12. Because of the frictional resistance of sealing members 58 and 48 and of pin 76, there needs to be restoration of almost the whole of the former pressure in chamber 12 before the net force is sufficient to re-set piston 16. However, re-setting is eventually accomplished, and, furthermore, extinguishing of the signal associated with the device, on such re-setting, provides evidence of the adequacy of the repair. When pressure is lost in chamber 13, resulting in movement of piston 16 to the right, sleeve 17 is prevented from moving by housing shoulder 66; the cross-sectional area of part 46 is again operative in chamber 13, but the cross-sectional area operative in chamber 12 is now that of part 51-less than that of part 46, so on restoration of lost pressure the device functions approximately as before, in a reciprocal manner. The sealing members now involved are 48 and 53. In Fig. 2 (not shown), the sleeve and shoulder arrangement shown at the left of Fig. 1 is adopted for both chambers, so the cross-sectional. area differences referred to above are now each equal to the cross-sectional area of the thinner end of a sleeve, whichever chamber loses pressure. In each case, the sleeve may be so shaped (as shown) that the cross-sectional area of either sealing member 58 or 53 is independent of the cross-sectional area difference referred to above. Reference has been directed by the Comptroller to Specifications 1,226,300 and 1,253,696.
