Title: Improvements in or relating to forced-flow vapour generators
IPC: F22B35/14
Filed: 1965-10-21
Abstract: 1,102,168. Steam turbine plant. BABCOCK & WILCOX CO. Oct. 21, 1965 [Oct. 22, 1964], No.44700/65. Heading F1T. [Also in Divisions F3-F4] A power plant comprises a condenser 31, pump 33, low-pressure heater 36, deaerator 37, feedpump 10, high-pressure feedwater heater 12, force flow once through vapour generator 14 including an economizer section 16, a vapour generating section 17 and a vapour superheater 18, and turbine 22 arranged in series in a closed circuit around which the working medium normally flows. On start up, a quarter full load waterflow is established through the circuitry to the vapour generating section 17, and then passes, since the turbine valves 44, 24, 25 are closed to flash tank 42. Valve 41 maintains full load pressure at the outlet of vapour generating section 17 throughout the start-up. Flash steam as it becomes available is passed to the turbine seal through conduit 59. Valve 44 in turbine by-pass 43 is then opened so that part of the fluid-flow from vapour generating section 17 passes through vapour superheating section 18 to the by-pass line 43, till predetermined conditions are reached when steam from the superheater under control of stop valve by-pass 25, together with saturated steam from flash tank 42 under control of valve 50 in conduit 55, is passed through valve 26 to roll turbine 22, at a pressure of about 50 psia. The turbine is then loaded to 5-10% full load by closing turbine by-pass valve 44, and to 20% full load by increasing the firing rate. Turbine control is then transferred from valve 25 to valve 26 causing check valve 60 in conduit 55 to close, whereupon valve 24 is opened wide and valves 25 and 41 close so all flows to and from flash tank 42 cease and the flash tank system pressure decays, normal turbine extraction flows being used for deaeration and feedwater heating. During the start-up any excess flash tank steam is discharged directly to the condenser 31. In modifications the turbine by-pass line from the superheater outlet may be routed through the flash tank, Fig. 2 (not shown) and a control valve may be incorporated between the superheater inlet and the conduit leading from the vapour generating section outlet to the flash tank.

Abstract: 1526444 Data transmission HONEYWELL INFORMATION SYSTEM Inc 31 Oct 1975 [20 Dec 1974] 45282/75 Heading H4P In a system for asynchronously transmitting binary data blocks, four data states are used (say 0, 1, 2 and 3) a binary 0 being represented by a change between states 0 and 1 or 2 and 3, a binary 1 as a change between states 0 and 2 or 1 and 3 and a block interval signal as a change between 0 and 3 or 1 and 2. As described the four conditions are 00,01, 10 and 11, the two digits being passed over different channels, a data 1 bit being signalled by a change in the first digit, a binary 0 by a change of the second and a block interval by a change of both digits. A further channel may be used to indicate readiness to operate. In Fig. 2 data from a source is accepted in register 203 together with a number in a 2 Î 4 stage counter 201 representing the number of bits in a block, both signals being translated into changes of state of flip-flops X, Y. A I bit reverses X and a 0 reverses Y. When the transmission of data has reduced the count to 0 X, Y are reversed and completion is signalled to the source. With flip-flop S giving 0, gate G also gives 0 and a new block data is received parallelly into 203 and a count is passed into 201 which changes S to 1 so that 201 is counted down as 203 is shifted. The circuit changes are clocked by T whose rate is unknown to a receiver. At the receiver Fig. 4 signals A, B on separate channels are received into flip-flops 407, 408 and passed into shift register 401 according to the following rules:- Register A B input Counter 0-1 No change 1 +1 or 1-1-0 No change 0-1 0 + 1 or 1-0 If A, B change simultaneously, data from register 401 and counter 403 are delivered to a utilizing device which is advised of the transfer by setting a flip-flop S to 0 and the device acknowledges this by resetting S to 1 which resets counter 403.

C. signal from an A.C. source 20 and being biased so that it is rendered conductive only when the transistor 6 is cut-off. In the arrangement shown, excessive load current causes sufficient voltage across a resistor 13 to render the thyristor 12 conducting and so reduce the potential at the base of the transistor 6 that it ceases to conduct. A biasing potential is no longer supplied from the load side of the transistor 6 through a resistor 23 to the transistor 17 so that the A.C. signal from the source 20 renders the transistor 17 conducting to short circuit the thyristor 12 to render it non- conducting so restoring the supply through the transistor 6. The A.C. source may be an oscillator 20, or may be provided by tappings on the secondary winding of the supply transformer 1, Fig.3 (not shown), or the A.C. signal may be derived from the audio frequency input to an amplifier forming the load supplied by the arrangement, Fig. 4 (not shown).
