Title: Apparatus for reversing the flow of liquids or gases in the delivery pipes from a single or multistage centrifugal pump or fan
IPC: F04D29/50
Filed: 1928-09-18
Abstract: 323,015. Marshall, R. Sept. 18, 1928. Liquid-piston pumps.-In a pressure-fluid system in which a fluid is caused to flow alternately in opposite directions to act upon some form of mechanism, or upon another fluid, the reversal of flow is effected by an endwise movable valve which is moved at timed intervals by hydraulic or electromagnetic means under the control of a device rotated at reduced speed by a power drive, for instance, by the shaft of a centrifugal pump constituting the source of pressure of the system. Fig. 1 shows a centrifugal pump 1 with a pistonvalve device 5 connected to the pump delivery and return pipes 3, 4, and to external conduits 15, 16. The piston valves 9, 10 are periodically moved by a servomotor 20, the actuating fluid for which is taken from the pump 1 and admitted under the control of a valve 28 driven by worm gearing from the pump shaft 2, so as to give a reciprocating flow in the conduits 15, 16. The piston valves may be replaced by a D slide-valve and may be actuated electromagnetically. The reciprocating flow of a suitable liquid such as water or oil may be utilized for the pumping of inflammable or corrosive liquids. An arrangement for pumping petrol is shown in Fig. 3. The reciprocating flow of water from the conduits 15, 16 passes to two tanks 50, 51 and by its action draws in petrol from a tank 55 through pipes 56, 57 fitted with non-return valves 60 and discharges it through delivery pipes 61, 62 also fitted with non- return valves 65. Perforated diaphragms 63 are fitted in each tank 50, 51 and the levels of the water are arranged not to pass therebeyond but preferably to oscillate between the levels a-b; a cock 54 in a, connecting pipe 53 permits adjustment before starting. A remote reciprocating pump may be driven by the reciprocating flow. The device, driven by any suitable power, may be applied to a fluid pressure system to provide an alternating flow of fluid which may be utilized to actuate a pump. The device may be used to give a reciprocating flow of liquid through keirs or the like.

Title: Improvements in means for venting tanks and other vessels
IPC: B64D37/00
Filed: 1935-09-27
Abstract: 462,750. Fluid-actuated valves. DODSON, E. Sept. 27, 1935, No. 26741. [Class 135] [Also in Group XVII] A vent for admitting or supplying air to tanks or other vessels to replace fluid drawn therefrom, for use, e.g. in connection with aircraft, comprises a compressed air supply orifice e and an aperture b<2> communicating with the atmosphere, these apertures being controlled by means of a diaphragm c clamped between opposed cup members a, b, member a communicating through a passage a<1> with an opening d in the tank d<1>, and member b communicating with a valve chamber b<3> and, through a passage b<1>, with an opening d<2> in the tank. A valve e<1> closes the inlet e and a valve c<1> on an extension c<2> of the diaphragm c controls the passage between cup member b and valve chamber b<3>, a spring c<3> tending to keep valve c<1> on its seat. An extension c<4> on valve c engages a ball valve e<1> when diaphragm c moves to the left. If the tank pressure falls below a predetermined amount valve e<1> opens to admit compressed air. If the tank pressure exceeds a predetermined amount, this pressure moves diaphragm c to the left against the pressure of spring c<3> and of the atmosphere and closes valve e<1>. Emergency relief valves are constituted by a chamber f containing a diaphragm g forming spaces f<2>, f<3>, of which the former communicates by a passage f<4> with the interior of the tank. The diaphragm g carries a yoke g<1> connected at one end to a positive pressure valve g<2> and at the other end to a negative pressure valve g<3> controlling outlet and inlet ports f<5> f<6> respectively, communicating with space f<3> which communicates with the atmosphere through a passage f<7>. Undue fall of pressure in the tank causes diaphragm g to rise and open valve g<3> to allow air to enter the tank, whereas undue rise of tank pressure causes the diaphragm to open valve g<2> to allow air to flow out. The valves c<1>, e<1> may be united into a unitary structure. When pressure air is not used, the channel e leads to the atmosphere ; suitable adjustment of the springs permits the same valve system to be used.

IPC: F16J15/32
Filed: 1965-06-25
Abstract: 1,117,392. Water softening. L. W. FLECKENSTEIN and A. J. FLECKENSTEIN 25 June. 1965, No. 27075/65. Heading B1J. [Also in Division F2] A piston valve, for water softening apparatus, in which six spaced sealing rings alternate with the spacing rings. A cycle of the apparatus is controlled by a timer motor 13 which positions the valve. In the position shown, hard water entering at 14 goes through connection 17 to the softener 67, Figure 6 (not shown). The softened water returns through a connection 16 and passes through the valve to a service outlet 15. At the same time, a separate brine control valve (55) Figures 5, 7, and 8 (not shown) which is also controlled by the timer motor, is closed, so that no brine can enter a chamber between two injector nozzles 43, 44. In a second or backwash position of the valve to the extreme right, hard water from inlet 14 passes through the hollow interior of the valve to service outlet 15. Some of this water goes out through connection 16 to backwash the softener and is discharged, via connection 17 through the valve to a drain port (50), Fig. 5, connected with an intermediate one of the annular passages 32. The brine valve 55 remains closed. In a third or brine and rinse position. Fig. 3 (not shown) hard water again goes straight through to outlet 15 and also flows through a filter 38 and thence through the injector nozzles 43, 44 so that, the brine valve 55 now being open, brine is delivered to the softener through connection 17 and discharged through connection 16 and drain 46a. On a predetermined fall in level of a brine tank (72), an air check (71) closes brine line 64 and rinsing begins. A fourth or brine tank filling position allows both normal service operation and filling of the brine tank with makeup water. Brine valve 55 is open and hard make up water can pass through pipe (64) to the brine tank. A known flow regulator (70) in line (64) allows full flow when the softener calls for brine, and restricted flow in the reverse direction when make-up water is supplied.

[Class 78 (ii).] Electric plant.-A lift system with pushbutton control is so designed that by pressing one of a series of buttons at a floor, the cage is brought to the floor, and after the caller has entered it, travels to the desired destination without further action on the part of the caller. Although no buttons are provided on the cage, it may have a switch for initiating movement in the up and down directions in case of emergency. A number of floor magnets is provided at each floor corresponding to the number of the floors to be served which register the calls for the various floors, but transmit them to the corresponding magnets of the destination floors only after the call to the station of a waiting passenger has been executed. If the cage is at a floor and a button is pressed there, this call is registered at once, but the cage begins its travel only after the well door has been opened and shut. If the cage is stationary at a floor and a call is made at another floor, it commences its travel immediately.
