Title: Deaerating apparatus for liquids
Inventor: BAKER CHARLES IVAN
IPC: B01D19/00
Filed: 1962-05-11
Abstract: 984,307. Deaerating liquids; hot water systems. A. M. CASTLE & CO. May 11, 1962, No. 18202/62. Heading B1M. A deaerator for removing dissolved gases from liquids, e.g. the water of a circulating hot water system, comprises an upper tank 13 and a lower tank 14 which are alternately put under vacuum while the liquid flows from one to the other, whereby the dissolved gases are released from the liquid. The deaerator shown is connected to line 2 which returns water to the heater of the hot water system. Water is diverted from line 2 through pipe 3 and check valve 5, and is admixed with make-up water supplied via line 7 and valve 8. The stream of water passes through reducing-valve 6 and enters tank 13 via a throttling tube 9 and inlet 10. The bottom of tank 13 is connected to tank 14 via drain conduit 16 and diaphragm valve 18. Deaeration of the water takes place in tank 13 because the tank is under vacuum, and the gases evolved are forced out of the tank via inverted check valve 25, line 22, and check valve 23, by the rising water level in the tank. The water level continues to rise in tank 13 until the water covers electrode 47 when an electrical circuit is energized, causing pump 32 to start up and to commence drawing deaerated water from tank 14. The increased pressure of the water at the pump outlet 23 is communicated to the diaphragm of valve 18 via line 19, and causes this valve to close, thereby closing conduit 16. The deaerated water from tank 14 is pumped via line 35 and a three-way diaphragm-valve 37, back into tank 13 and fills this tank completely, thus displacing all the evolved gases from this tank, until the water closes valve 25. The pressure of water then builds up in tank 13 and on the diaphragm of valve 37 until the pressure is sufficient to cause valve 37 to reverse its direction, thus diverting the flow of deaerated water from pump 32 through check valve 40 and conduit 39 back into the heating water line 1 of the hot water system. The withdrawal of water from tank 14 by pump 32 creates a vacuum in this tank, causing any dissolved gases still present in the water to be evolved. Pump 32 continues pumping the water from tank 14 until the level of water in conduit 45 falls below a lower electrode 48, whereupon the pump stops and valve 18 opens. Water is now transferred from tank 13 to tank 14 via conduit 16, and a vacuum is created in tank 13 by the removal of the water. During this period of transfer of water, any gases evolved in tank 14 are displaced into tank 13 via conduit 45 and valve 46. When tank 14 is filled with water, tank 13 will contain a level of water several inches below electrode 47, and a vacuum will exist in the upper section of tank 13. The cycle of operation of the apparatus now repeats itself with a fresh supply of water entering from line 2.

Filed: 1960-05-24
Abstract: 898,258. Transistor pulse circuits. ERICSSON TELEPHONES Ltd. March 24, 1961 [May 24, 1960], No. 18205/60. Class 40(6). A pulse delaying circuit comprises a constant current source, such as transistor Q1, normally feeding transistor Q2 except when Q2 is cut off by an input pulse Vin when the constant current is diverted to charge capacitor C until voltage -Vb 3  is reached when the charge is limited by conduction of transistor Q3. At the end of the pulse Vin, capacitor C discharges via Q2, transistor Q3 being cut off, terminating the output pulse. In Fig. 3 (not shown) pulse Vin is derived from the transformer of a blocking oscillator and an inverting transformer is included in the output circuit. A diode is included in the base circuit of Q2 to limit the discharge current. Hole storage effects are limited by preventing bottoming of Q1, Q2. The pulse delay period is adjustable by variation of C or R1.

Abstract: 1,149,652. Equalizing system. WESTERN ELECTRIC CO. Inc. 27 April, 1966 [7 May, 1965], No. 18369/66. Heading H4R. An equalizer at an intermediate station in a transmission system is controlled from a main station by command signals fed over the system and used to set a memory device at the intermediate station to one of a number of states, the memory device being connected to the equalizer to adjust the equalizer to a frequency response condition corresponding to the memory condition. Fig. 2 shows equalizing equipment at an intermediate station in which 5 equalizer sections are provided each independently adjusted and each compensating a respective portion of the pass band of the receiver. Command signals received at terminal 39 are tapped off at point A and fed via line 79 to the command receiver 80. The command signal comprises a two out of eight voice frequency code on a carrier just outside the conventional service band of the system, and the various code combinations are used to provide increase or decrease of the count of any of the binary counters 64 to 68, or to operate either of the switches 81 or 82, to connect the outputs of the test frequency generators respectively to the input or the output of the equalizer section. In operation an attendant at the main station would command the test oscillators to be connected to the line, the frequencies of these oscillators corresponding to the centre frequencies of the effective bands of the five equalizers, and, by analysis of the signal levels at the main station, determine the adjustment required to the five equalizers. By sending pulses of the appropriate frequencies the count in the appropriate binary counters 65 to 68 can be increased or decreased to cause via the decoders 75 the appropriate modification of the heater currents of thermistors 58 to 62 to provide the required equalization. A command receiver comprising a bank of band pass filters and peak detectors connected via a matrix to a bank of " and " gates is described with respect to Fig. 4 (not shown). The command signals are fed ,Fig. 1 (not shown) from a first main station (17) over, e.g. the westbound channel (22) to a second main station (16) where it is fed via a command signal band pass filter (26) to the other, e.g. eastbound channel (12) for transmission to the intermediate repeater (14). Test signals generated at the intermediate repeater (14) are fed on to the, e.g. eastbound channel (12) to the first main station (17) to be analysed there to derive information required for the subsequent adjustment of the equalizers by further command signals.

Abstract: 835,308. Steam superheaters. SULZER FRERES S.A. June 11, 1957 [July 11, 1956], No. 18417/57. Class 123(3) In a steam generator operating at high, for example supercritical, pressure, overheating of radiantly-heated reheater tube platens disposed in the generator furnace is prevented by enclosing the more intensely heated marginal areas of the platens by tubes through which flows high pressure steam or water. As shown in Fig. 1, in the generator 1 which is heated by burners 17, the working fluid enters at 2 and passes through a feedwater preheater 3 and vaporizing section 4 to a convection superheater 6. From here the steam flows to a second superheating section 7 forming a wall lining for the upper part of the combustion chamber and thence through tubes 8 enclosing the marginal areas of a reheater platen 12. The steam then flows through a final superheater 9 to a high pressure turbine 10..From the high pressure turbine the expanded steam flows through the reheater platen 12 and a second reheater section 13 to the low pressure turbine 14. In modifications the marginal protective tubes for the reheater platen forms part of the vaporization section or of the feedwater preheater. Thus the stream of heating gases from the furnace cannot impinge directly on the reheater tubes which, particularly when operating at low load or when starting up, do not carry steam at sufficient pressure to ensure adequate cooling. As shown in Fig. 5, the marginal tubes 8 may be bent to form several passes under the reheater tubes 12. Where it is only necessary to protect the bottom and one side of the reheater the arrangement shown in Fig. 6 is adopted.

Title: A process for the production of thioether glycols
Filed: 1957-06-13
Abstract: Thioether glycols containing a plurality of thioether groups in the molecule are prepared either by reacting an alkylene oxide with hydrogen sulphide in the presence of a sulphur analogue of carbon dioxide or a substitution product of carbon dioxide, or by reacting an alkylene oxide with excess hydrogen sulphide above 140 DEG  C. Alkylene oxides mentioned are ethylene oxide, propylene oxide, glycide alcohol, epichlorhydrin, phenoxy-propene oxide, cyclohexene oxide and styryl oxide.  Sulphur analogues mentioned are carbon disulphide, carbon oxysulphide, mono-, di- and tri-thiocarbonic acids and their salts and esters, thiourea, thiocarbamic acid and its salts and esters and thiocyanic acid and its salts and esters.  The reaction is advantageously carried out in the presence of a thioether glycol.  The presence of large-surface bodies such as active carbon or silica gel is also advantageous.  For carrying out the first embodiment it is advantageous to use a mixture of about 2 mols. of alkylene oxide with about 1 mol. of H2S and about 0.1 to 1 mol. of the sulphur analogue, and elevated temperatures up to about 100 DEG C. The reaction is preferably effected in a packed column.  The sulphur analogue may be added dropwise during the reaction, or may be added to the alkylene oxide or H2S beforehand.  In examples: (1) to (4) products containing thiodiglycol, triethylene dithioglycol, tetraethylene trithioglycol and higher homologues are prepared by reacting ethylene oxide with H2S in the presence of thiodiglycol and (1) and (2) CS2, (3) COS, and (4) excess H2S at 150 DEG  C.; (5) propylene oxide is reacted with H2S in the presence of dioxydipropyl sulphide and CS2; (6) propylene oxide is reacted with excess H2S at 160 DEG  C. in the presence of dioxydipropyl sulphide.
