IPC: G01N29/024
Filed: 1991-04-25
Abstract: PCT No. PCT/SE89/00615 Sec. 371 Date Apr. 29, 1991 Sec. 102(e) Date Apr. 29, 1991 PCT Filed Oct. 31, 1991 PCT Pub. No. WO90/05283 PCT Pub. Date May 17, 1990.In a method for measuring the mass flow M of a fluid flowing through a pipe having a cross-sectional area A, the sound velocity c2 in the fluid is determined as well as the flow velocity v of the fluid by sing-around technique. Further, reflection technique is used which comprises measuring the amplitude both of an ultrasonic pulse which has been reflected in a boundary between a first and a second material having different acoustic impedances, and of an ultrasonic pulse which has been reflected in the boundary between the second material and the fluid, it being possible to determine the density of the fluid on the basis of the measured amplitudes, the sound velocity c2 in the fluid and the acoustic impedances of the first and the second material. The mass flow M is then obtainable as M=vxAx rho 2. A mass flowmeter especially has a transducer with a piezoelectric crystal (5), a first block (6) of a first material disposed adjacent said crystal, and a second block (7) of a second material disposed between the first block and the fluid, and calculating and amplitude metering means (10 and 12).

Title: Improvements in or relating to the purification of chlorine
Inventor: SUTTER ROBERT CARL
IPC: C01B7/07
Filed: 1955-01-04
Abstract: <PICT:0767792/III/1> To remove organic impurities, gaseous chlorine is passed through a bath of liquid chlorine, and then countercurrently to a flow of liquid chlorine in a column.  Chlorine gas, after concentrated sulphuric acid treatment to remove water, say at 35 psig. and 120 DEG F., passes through pipe 6 and inlets 4 or 5, dipping below the liquid chlorine surface, into sludge tanks 1 or 2, which are provided with hot or cold water temperature regulating systems. Chlorine at say 28 DEG F., free from most impurities, passes through outlets 20 or 19, and pipe 21 to scrubbing column 22, having packing 30 on grid 31.  The chlorine rises through column 22 countercurrent to liquid chlorine and passes out through 32 to condenser 40, where part of the chlorine is liquefied by circulating brine, while the remainder is withdrawn as purified gas at 45. Liquid chlorine is returned from condenser 40 through 46 to the top of the scrubbing tower 22 and collects in the well 23, whence it may be passed to sludge tanks 1 or 2, through pipes 25, 26, to maintain a constant level of liquid chlorine in the sludge tank, and make up for chlorine evaporated by the gaseous chlorine passing trough the tank. Sludge tanks 1, 2 are used alternately and, when one is saturated with impurities, the gaseous chlorine is diverted to the other, while the first is cleaned by applying vacuum to pipe 10 or 11 to withdraw vaporizable material, or by allowing evaporation through pipe 21 while heating the tank, and by discharging sludge through drains 8, 9.  The tanks may be refilled with liquid chlorine through pipes 48 from condensers 40, although it is possible to operate the process without first filling the sludge tank with liquid chlorine.  In Fig. 2 (not shown) an alternative apparatus is shown, where the bath of liquid chlorine is situated in the well of the scrubbing column and the condenser is replaced by a brine refrigerating coil in the top of the column.

Title: Heart and lung resuscitator
Inventor: HEWSON CARL E
IPC: A61M16/00
Filed: 1966-01-04
Abstract: 1,140,581. Heart and lung resuscitators. C. E. HEWSON. 4 Jan., 1966, No. 365/66. Headings A5R and A5T [Also in Division G3] A lung ventilator comprises a duct 69, 70 and a fitting 14 for introducing lung-ventilating gas to a patient, a fixed volume tank 58 for metering the amount of lung-ventilating gas and connected to the duct, means for introducing a controlled amount of lung-ventilating gas into the tank and valve means 60 in the duct for connecting and disconnecting the tank and the fitting, the said introducing means and said valve means being so arranged that gas is introduced to the tank only when the tank is not connected to the fitting. The lung ventilator is combined with a heart resuscitator comprising a pneumatically operated compressor 12 for exerting pressure on the heart and includes a pneumatic circuit for cyclically operating the lung ventilator and the compressor in timed relation to each other. The control means is disposed in a case 22 which is shaped to form a shoulder lift and which includes a combined handle and head support 38. Straps 16 retain the compressor 12 on the patients chest. The device includes a respiratory mask 14. Oxygen from a supply 18 at 90 p.s.i. flows through an 'on-off' valve 48 and a pressure regulator 52, which reduces the pressure to 48-50 p.s.i. to a pneumatically controlled valve 54 which normally connects the supply to a line 70. A pneumatic pulse generating circuit 56 (see Division G3) is then energised and emits gas pulses at its outlet 78 at 60 per min., and the metering tank 58 is filled under the control of an adjustable regulator 82. A pneumatically controlled valve 60 between the tank and the mask is normally closed. The gas pulses are supplied through a pilot line 68 to a valve 62, which opens in response to each pulse, to direct oxygen in a line 50 through a regulator 82' to the cardiac compressor 12. The gas pulses also operate a counter 64 in a pilot circuit 66 to permit the valve 54 to change over so that oxygen is supplied to a pilot line 72 and disconnected from line 70 only once in every five pulses. When oxygen is supplied to the pilot line 72, the valve 60 is opened to connect the tank 58 with the mask. The valve 60 (see Division F2) includes a spool (118, Figure 5) which, as it moves to open the valve, provides a flow path of increasing dimensions so that the gas volume passing to the mask increases gradually at a predetermined rate. As the tank empties or reaches a preselected minimum pressure, pressure in a pilot line 113 closes a normally open valve 111 to change over the valve 54 to connect the oxygen supply to the line 70 and disconnect the line 72.
