Title: Method and apparatus for recovering pure water from an aqueous salt solution
IPC: C02F1/06
Filed: 1972-05-15
Abstract: 1377577 Distilling water in multiple effect apparatus SASAKURA ENG CO Ltd 15 May 1972 [14 May 1971] 22777/72 Heading BIB Pure water is obtained from salt solution in a multi-effect apparatus in a process in which the solution is introduced into upper units of at least two horizontally adjacent columns of superposed evaporating units each containing heat exchanging means, vapour produced by evaporation of solution in a unit of any column being passed into the heat exchanging means of a substantially adjacent unit in another column and which operates at a lower pressure and temperature, whilst solution not evaporated in a unit is allowed to flow onto the heat exchanging means of a lower unit of the same column, which unit is at a lower temperature and pressure whereby in each unit at least some vapour is condensed in the heat exchanging means and at least part of the solution is evaporated by contact with the heat exchanging means. In Fig. 1, the solution is divided into two streams which are passed through lines 23 and 24 down evaporator series A. and B respectively, where evaporator 4-2 operates at a temperature and pressure lower than evaporator 4-1, and evaporator 4-3 operates at a temperature and pressure lower than 4-2, &c., the water vapour formed in evaporator 4-1 being passed via demister 9-1, Fig. 3, through the heating tubes 5-2, Fig. 2, of evaporator 4-2, the vapour formed in evaportor 4-2 being passed via demister 9-2, Fig. 4, to the heating tubes of evaporator 4-3 &c Steam is passed through tubes 5-1, Fig. 3, and condensed water collects in distilled water well 14-1, Fig. 2 of evaporator 4-1, and flashes through small holes 15 into the distilled water well 14-3 of evaporator 4-3 immediately below where it combines with the vapour produced in unit 4-2 to enter heating tubes 5-3 and on condensation accumulates in distilled water well 14-3, Fig. 2, of evaporator 4-3, and so on. The distilled water condensed in heating tubes 5-2 of evaporator 4-2 similarly flashes into the distilled water well of evaporator 4-4 and thence passes with water vapour from evaporator 5-3 through the heating tubes of evaporator 4-4. Distilled water is' collected at 25. Before being divided. into two streams, the brine is intially introduced through 16 where it passes through condensing coil 11, after which it is cycled to brine well 20 where it mixes with brine already treated. A stream of this mixture is drawn off via pump 13 and pases up through coils 10 to be divided into the two streams.

Abstract: 1282395 Two-way transmission INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [31 March 1970] 22790/71 Heading H4R In a system for conveying video signals in one direction over a line and digital data signals in the opposite direction over the same line hybrid circuits are located at the ends of the lines to prevent interaction between the two signals at the respective receivers. As described the video signal is transmitted from a data processing system at 11 to a display device 19 while a digital data source 17 located with the display device provides signal, controlled by a keyboard 84, to be transmitted to the data processor 46, preferably during the horizontal synch pulse interval in the video signal. The video signal is fed to the cable 15 via buffer amplifier 23 of unity gain, with the data signal output derived between the input and the output of the amplifier via a differential amplifier 29 so that the video signal is cancelled in the differential amplifier and only the data signal is applied to the processor. At the other end of the cable the display device is fed via an inverting amplifier 49 of gain 2 with the digital data signal applied to both the input and output of the amplifier 49 via respective resistors 76, 78, so that the data signal is cancelled at the amplifier output and therefore does not appear at the display device. The data signal originates at a keyboard 84 the state of which is set into the shift register 86 via gates A1 to AP, AP being a parity bit, and the shift register being read out to line during the horizontal synchronizing pulse of the video signal to minimize interference on the display device.

Filed: 1938-08-05
Abstract: 517,491. Photographic cameras. KODAK, Ltd. Aug. 5, 1938, No. 23167. Convention date, Aug. 18, 1937. [Class 98 (i)] A camera using perforated film has a ratchet wheel 17 secured to the shaft for the take-up spool 12, which is latched against movement by a spring- controlled pawl 18 brought into the latching position by a pin, 26 which turns with a film-engaging sprocket 6. The pawl 18 is pivotally mounted on a shaft 19 which is axially movable, thus enabling it to be released from the latching engagement. The shaft 19, Fig. 6, carries one or more flat portions 20 and one or more shoulders 21, a pin 22 holding the pawl in place. The hooked end 23 of the pawl 18 engages the teeth of the ratchet wheel 17. The sprocket 6 and a gear wheel. 25 carrying a pin 26, are carried on a shaft 24, and when the take-up spool is rotated, the pin is moved to strike the slanting edge 27 of the pawl arm 28, and cause the hook 23 to lock the ratchet wheel 17 and the take-up spool. The shaft 19 is urged outwardly by a spring 29 and is provided with a pushbutton 28. When the latter is depressed, the pawl is moved out of the path of the -pin 26 and is turned by a spring 31 to release the hooklike member 23 from the ratchet wheel 17. The film can. then be wound on. In winding the film back into the cassette, the pin 26 passes under an upwardly bevelled edge 33 of the pawl 18 which depresses the spring 29 and allows the pawl 18 to rock idly over the end of the pin so that the hook 23 does not engage the ratchet. A counting dial and pointer are driven from the gear wheel 25 through a second gear wheel- 36.

Filed: 1976-06-04
Abstract: 1530665 Acoustic wave devices WESTERN ELECTRIC CO Inc 4 June 1976 [9 June 1975] 23197/76 Heading H3U An acoustic wave device comprises a body of lithium niobate or lithium tantalate with at least one region of diffused metal to increase the wave velocity therein. The metal is preferably a transition metal, e.g. titanium, nickel or chromium. A filter 14, Fig. 1, comprises a pattern 22 of parallel diffused stripes oriented at 45 degrees to the direction of wave propagation between input and output transducers 18, 29. Waves at a frequency f 1  are reflected towards a second output transducer 23, waves at other frequencies being unaffected so that the device acts as a channeldropping filter. The magnitude and bandwidth of the dropped channel may be determined by varying the amount of diffused metal in each stripe and the spacing of the stripes. In other embodiments, the diffused stripes are perpendicular to the direction of wave propagation and the device acts as a rejection filter at the frequency corresponding to the stripe separation. Fig. 3, not shown, depicts such a device in the I.F. circuitry of a T.V. receiver. Other uses envisaged are: a notch filter (Fig. 2, not shown), a resonator, and a pulse compression device. A waveguide 62, Fig. 4, comprises diffused regions 64 on either side of a desired channel 71. As shown, surface waves are employed but bulk waves may alternatively be used, in which case a further diffused region may be provided beneath channel 71. In another embodiment metal is diffused into a drawn fibre 82, Fig. 5, by a method which is described.

Abstract: 1,010,046. Pipe couplings. CARLSBERG BRYGGERIERNE. June 4, 1964 [June 8, 1963], No. 23279/64. Heading F2G. An extractor for beer kegs comprises a cover 1 with a downwardly extending flange socket 2 to which an extractor cup 4 is secured by means of a bayonet joint 3 the extractor cup being of larger diameter than the socket to provide a channel 5 communicating with the inside of the keg, a spigot 14 and a spring-loaded valve 9. The valve 9 has a substantially quarter-circular seat 8 co-operating with a sealing ring 7 of circular cross-section and a quarter circular seat 6 in the flange 2 to seal the extractor. The spigot 14 has projections 15 to form a bayonet lock with recesses 16 in the cover and has a dispensing tube 17 provided with several slots 18 at one end and a quarter circular valve seat 20 above the slots. In operation the spigot is inserted in the socket to contact and lower the valve 9. The valve seat 8 extending slightly more than a quarter circle, carries the sealing ring with it until the ring contacts a seat 13 in the extractor cup 4. In the looked position of the spigot the seat 20 on the dispensing tube 17 contacts the ring 7, thus separating channel 5 from the interior of cup 4. Hence carbon dioxide passing through a channel 22, 23 in the spigot passes through the channel 5 and into the top of the keg to force beer up through the cup 4, through the slots 18 and up through the spigot 14.
