Title: Improvements in or in connection with the supply and distribution of gas, water and other fluids
IPC: G05D16/20
Filed: 1925-06-02
Abstract: 256,001. Pillinger, G. C., and Sunderland, L. June 2, 1925. Controlling.-In a supply and distribution system for gas, water or other fluid, a pressure-augmenting means such as a centrifugal or other pump placed at some point in the system is arranged so that when normal conditions exist fluid can flow directly through the pressure-augmenting means into a reservoir while when the demand for the fluid exceeds the supply the pressure-augmenting means are brought into action electrically until normal conditions are restored. In the apparatus shown, water from the main 11 flows through the centrifugal or other pump 12 into the reservoir 14 from which it is drawn off as required through the service pipe 15. The pump 12 is driven by an electric motor 16 which is started and stopped by the needle 48 of the pressure gauge 17 engaging with contacts 46, 47. The electric circuit comprises a main switch 24, 25, fusible cut-outs 28, 29, a circuit breaker A, a motor starter B, and a relay C. The circuit breaker A includes a series coil 31, a shunt coil 32, a drag coil 33 and a switch 34, an ammeter 35 being connected between the coils 31, 33. The motor starter B comprises a solenoid 43 operating an arm 37 which is movable in relation to the studs 38 of a resistance which is cut out of the armature circuit and inserted in the field circuit. The relay C comprises a switch blade 52 carried by a member 53 which is rocked by energizing windings 44, 45 so as either to break or to complete at terminals 50, 51 a circuit in shunt with the solenoid 43. When needle 48 is in contact with the contact 47 a circuit is completed from the supply mains through the relay winding 45, thereby operating the switch blade 52 to shortcircuit the solenoid 43 of the motor starten B. As the pressure falls the electric circuits remain unaffected until the needle 48 reaches the contact 46 when a circuit including the relay winding 44 is closed and the switch blade 52 is opened to remove the short-circuit on the solenoid 43. The solenoid 43 then raises the arm 37 into contact with the resistance studs 38 and starts the motor 16 which runs until normal pressures conditions are restored, when the circuit including the relay winding 45 is completed by the needle 48 engaging with the contact 47. As a modification the electric motor 16 may be arranged to start up an internal-combustion engine driving the pump 12 and the motor may act as a generator for charging a secondary battery supplying current to the system when required. As a further modification the diminution of pressure in the supply system may be arranged to actuate an electric relay operating a valve controlling a supply of compressed air for starting up the internal-combustion engine driving the pump.

Abstract: 239,936. Porter, H. G. June 19, 1924. Pressure-regulating valves.-A pressure-regulating valve of the kind comprising a lift main valve actuated by fluid pressure acting on a piston under the control of an auxiliary valve consisting of a pair of pistons on a common rod arranged so that the actuating fluid always passes between the pistons is adapted to be actuated solely by the outlet pressure acting against an adjustable spring load. In the form shown in the Figure the main valve 5 co-operates with a seat 4 and is directly connected to the actuating piston 6. The control valve pistons 8 work in a cylindrical casing provided with a port 9 connecting the space between the pistons with the space above the main piston, with a port 10 leading to the inlet and with ports 11, 12 leading to the outlet side of the main valve. In the event of the outlet pressure rising above the desired value, the pressure admitted through the port 12 raises the pistons against the action of the spring 13 and admits inlet pressure above the main piston at the same time closing the passage to the outlet side. In a modification inlet pressure is admitted to open the valve. A pipe 16 connects the space above the pistons to atmosphere. According to the Provisional Specification this pipe may communicate with the exhaust pressure.

Abstract: 544,355. Electro-static precipitating apparatus. LODGE-COTTRELL, Ltd. (International Precipitation Co., Inc.). Oct. 7, 1940, No. 14947. [Class 39 (i)] In apparatus for the electro-static precipitation of particles suspended in gases, of the type in which the gas is passed in succession through an ionizing field and then through a field which causes the charged particles to deposit on a collecting electrode, as described in Specifications 512,313, 536,753 and 540,508, the collecting electrode is constructed so that the main collection of the deposited particles takes place in a space shielded from the main gas stream. As shown in Fig. 1, the gas treating .chamber comprises two co-axial cylinders 10, 14 connected to earth and to the inlet and outlet gas conduits 17, 12. The high tension electrode consists of a part 20 of extended area so as to prevent corona discharge, and a fine wire electrode 27 connected thereto mechanically and electrically by an intermediate member 26. The wire electrode 27 provides the corona discharge for ionizing the gas and charging the particles and the intermediate part 26 is long enough to remove it from the effective influence of the non-discharging electrode 20. The part 14 of the collecting electrode opposite the part 20 of the high tension electrode is of a permeable structure such as mesh, expanded metal &c. The part 16 opposite the ionizing electrode may be solid, as shown, or permeable, and aligns with the part 14. A modification is described for horizontal, flow apparatus. In another modification, Fig. 6, the ionizing field is provided by fine high tension wires 61 alternating with large earthed tubes 60 disposed in line transversely across the gas stream, in the inlet end of the apparatus. The wires 61 are stretched between pairs of arms 63 on a frame 62 which is hung by hooks 65 on a bus-bar 64. The precipitating field is provided by high tension plate electrodes 72 suspended on transverse rods 73 one of which is connected to a lead 76, and earthed collecting electrodes consisting of spaced strips 71, of flat, curved or angular shape, disposed transversely of the direction of the gas stream and one behind the other. The strips are carried by rods 80 supported at their ends in longitudinal bars 82 which rest at their ends on transverse rods 83.

Abstract: 17 - Hydroxy corticosterone - 21 - b  - cyclopentyl propionate is prepared by reacting 17-hydroxy corticosterone with b -cyclopentyl propionyl chloride or bromide in the presence of a tertiary amine, e.g. pyridine or dimethyl-aniline.  Other methods for the esterification may be employed, e.g. the ester interchange of a lower alkyl ester of b -cyclopentyl propionic acid with 17 - a  - hydroxy corticosterone, or azeotropic esterification using b -cyclopentylpropionic acid in the presence of benzene or toluene and p-toluene sulphonic acid or boron trifluoride.  In examples: (1) 17-hydroxy corticosterone in pyridine is treated with b -cyclopentyl propionyl chloride, the desired 17-hydroxy corticosterone-21 - b  - cyclopentyl propionate is isolated by solvent extraction.  Other examples relate to various therapeutic compositions incorporating the ester, which exhibit a prolonged adrenal cortical hormone-like activity (see Group VI).ALSO:Therapeutic compositions having a prolonged adrenal cortical hormone-like activity comprise 17-hydroxy corticosterone-21-b -cyclopentyl propionate, (see Group IV(b)), in a non-toxic fluid vehicle, e.g. vegetable oils, glycols, thixotropic gels or water.
