Patent GB-642288-A (GB)
Title: System for dispensing measured quantities of liquefied gas
IPC: F17C13/02
Filed: 1948-07-16
Abstract: 642,288. Rotary meters. LINDE AIR PRODUCTS CO. July 16, 1948, No. 19210. [Class 110(ii)] [Also in Group XXIX] In a metering apparatus for low-temperature liquids such as oxygen or nitrogen, the meter 18 and the register mechanism 33 are not coupled together until a quantity of liquid has been passed through the meter to cool it to a temperature which is below the vaporization temperature of the liquefied gas. Fig. 1 shows a pressure-actuated device 44 which rocks over a lever 39 to close the coupling 36 when pressure rises in a pipe 28. A pump 19 circulates liquid from a container 10 through the meter and pipes 28, 29, valves 25, 30<SP>1</SP> and 26 being closed. When the meter is cooled and the pump 19 is fully primed, valve 28<SP>1</SP> is shut and valve 26 opened to commence delivery of the liquid, the closing of the coupling starting up the register 33. At the end of delivery, valve 28 is opened and 26 closed. Pressure in the pipe 28 falls and the coupling 35 is disengaged. If delivery of gas to high-pressure receivers through an outlet 22 is desired, valves 24 and 28<SP>1</SP> will remain closed and valves 25 and 30<SP>1</SP> opened. a pump 20 being used instead of the pump 19. When the meter is cooled, the valve 30<SP>1</SP> is closed and valve 27 opened and delivery commences through an outlet 22. Pressure in the pipe 30 acts on a device 50 to move a plunger 52 and rock over the lever 39. A heated vaporizer 23 may be used. Since the meter is on the suction side of either pump, the liquid pressure in the meter is unaffected by changes in delivery pressure on the discharge side of the pump. In Fig. 2 the pump 19 is before the meter 18 and magnetic means are used to close the coupling comprising an iron bar 61 and an electro-magnet 62, the ends of which are provided with windings 65 connected to slip-rings 66 on an insulating bushing 67. Contact brushes 68 are connected with a source 69 of electrical energy or to a pressure switch 70 or 71. The switches are actuated by pressure either from a pipe 128, when pump 19 is used alone, or 130 when the pump 20 is used with the pump 19 in series. A further arrangement includes a friction cone clutch for driving the register 33, the clutch being actuated by one of two pressure switches which cause the energization of a magnet to operate the bell-crank lever. In another device, manual operation of the clutch is effected by movement of one of two levers which engage a common bar 96 (Fig. 4, not shown), and at the same time the lever movement opens a valve in the pipe 30 or the pipe 28. Specification 584,460 is referred to

Title: Improvements in or relating to automatic electric substations
Filed: 1923-08-03
Abstract: 202,626. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Wensley, R. J., and Leonard, S. G.). Aug. 15, 1922, [Convention date]. Systeans for conversion employing rotary converters.-In an automatic substation system, a number of rotary converters are switched on to the direct current mains in succession according to the demand for current. The order in which the machines are called upon can be varied at will. If any machine fails to take up load within a predetermined time, it may be automatically disconnected so as to allow the next machine to come into use. The Figure shows an arrangement employing three rotary converters A, B, C, the connections of the machine A being shown in full, and those of the machines B and C only in part. A demand for current in the direct current circuit 4 acts through relays 8 and 39 to close a switch 5 between alternating current mains, 1 and a transformer 2, and also to close in succession switches 6 and 7 between the transformer and the converter machine 3. If the machine runs up correctly and feeds direct current to the line 4, other relays 1.2, 20 come into action and short circuit resistances 13, 14. Polarized relay apparatus is provided to ensure that the machine acquires correct polarity. It the demand continues to increase, a thermal relay 23 brings about the switching in of the next machine in order. The order in which the machines are called upon depends upon the setting of double pole switches 33, one associated with each converter. If, after starting, a machine fails to take up its load within the allotted time, retarded relays 27, 29 cut it out and bring in the next machine. Provision is further made through relays 30, 28 to cut out a working machine when its output sinks materially. Isolating switches 32 are also associated with each machine.
