Title: Improvements in or relating to the degassing of molten metal
IPC: B22D1/00
Filed: 1960-10-12
Abstract: In a process of degassing molten metal, particularly steel, the metal is partially degassed by streaming it into a ladle while subjecting the stream to a vacuum, and the partially degassed metal which collects in the ladle in the form of a pool is completely degassed by a vacuum and a purging gas which is bubbled upwards through the pool. The apparatus comprises a vacuum chamber 1 containing a receiving ladle 3, an inlet 50 for the supply of molten metal in the form of a stream from a supply ladle 2 which is seated on a movable cover section 20, and a purging gas inlet 141 which delivers the gas to the base of the ladle, Fig. 8. The cover section 20 is moved into position <PICT:0963012/C6-C7/1> by a lifting device 30 and is hermetically sealed to the ladle 2 by flange 24 and sealing ring 26 and is sealed to the ladle 3 by flange 22 and an O-ring seal 23.  A stream of molten metal from ladle 2 is directed into the vacuum chamber through a sleeve assembly 50 and the ladle 3 is provided with a nozzle 75 and a stopper rod 77 which includes a hollow refractory tube 84, Fig. 8, surrounding a gas purge inlet pipe 86.  A ceramic disc 87 of SiC is located between the bottom of tube 84 and the nozzle 75 and the gas pipe 86 is welded to a sleeve 90 fastened to a stud 92 with a bore 95 communicating with radial apertures 96 so that purging gas from inlet 141 is distributed into the melt. A radiation shield 110 is positioned above the ladle 3 in cover section 20 to prevent excessive heat loss.  To carry out the process the cover section 20 is positioned over the ladle 3, supply ladle 2 is located in position on the cover and the ladle 3 is then evacuated through conduit 14.  Molten metal from ladle 2 is streamed into ladle 3 and when a shallow depth of partially degassed metal has accumulated the purging gas is supplied to the pool.  A centrifugal dust separator is positioned between the vacuum chamber and the pumps and a dust shield 15 prevents molten metal carry over.

Title: Display apparatus
IPC: G09G3/00
Filed: 1974-08-09
Abstract: 1479921 Matrix displays INTERNATIONAL BUSINESS MACHINES CORP 9 Aug 1974 [17 Aug 1973 25 Jan 1974] 35122/74 Heading G5C Display apparatus comprises a display panel with discrete light emitting elements and a keyboard so positioned as to be operable by a viewer of the display and whereby the speed of a running display is regulated. The panel 8 may have 4 character positions each comprising a 7 x 5 matrix of elements. Data is moved across the panel by shifting the display one vertical column every two cycles. Data is stored in a message buffer and a five position character shift register. During each cycle the data in the register is shifted 5 steps thus returning to its original position; and is fed to the panel where it is displayed during each cycle. After 11 cycles one character disappears from the display and is replaced in the register by a new character from the message buffer. In a system including a gas discharge panel 8 with crossed conductor arrays, the row conductors are driven by a character generator 6 controlled by the register output and the column conductors, arranged in 4 groups of six, are energized by six position ring circuits via gating circuits which select the particular group. Each cycle comprises 24 pulses, during each cycle the 4 Î 6 counter 10 generates 24 pulses. During each pulse one column of elements is scanned and after 6 pulses i.e. when one character has been formed a pulse is provided to shift a new character into the first position of the register 13 and into the generator 6. The cycle is repeated until after N cycles the 1 to N counter 11 provides a signal which adds one to the counter 5 causing all the characters to be displaced to the left by one column. N is controlled by the keyboard 20 which also controls the frequency divider 2 thus varying the speed of running. Additional circuitry may allow a message to run back by providing a negative input to counter 5. When counters 5, 10, 11 synchronize a character is moved from the buffer 19 to the register 13. In another embodiment the panel comprises a matrix of LED's each column being controlled by a shift register. Alternatively the LED's are connected in rows and columns, the latter being earthed via a transistor (90) Fig. 9 (not shown) controlled by an element of a shift register. The panel may comprise an array of neon lamps.

Abstract: 885,268. Blow-down apparatus for forced flow steam boilers. SULZER FRERES S. A. Oct. 13, 1960 [Oct. 30, 1959], No. 35155/60. Class 123(2) In a method of removing salts from a forcedflow, once-through, steam generator of a steam power plant individual pipelines 11 exposed to salt deposition are connected cyclically through valves 16 with a washing conduit 17 the opening of each valve 16 causing a pressure drop of the working medium which, as wet steam, washes the salts from the respective pipeline. The working medium diverted during the washing process is fed successively through high and low pressure pre-heaters 6a, 3a respectively to an evaporator 20 with an outlet 21, a proportion being passed through a pipe 23 with a restrictor 22 to a feed-water tank 4. The pipelines 11 are provided with non-return valves 12 which are followed by a heater 13 connected through a pipe 14 with further pipes 15 situated beyond the salt deposition zone. In a modification, Fig. 3, not shown, the pipe 17 leads to a separator the vapour from which passes to the first turbine stage and the liquid to the low pressure preheater and the tank 4. In an alternative arrangement the vapour taken from the separator is fed through the high pressure pre-heater 6a to the tank 4. In a further modification, Fig. 2, which is suitable where the washing process is discontinuous the simultaneous closing of all of the valves 16 causes in a line 31 a pressure drop which is sensed by an impulse transmitter 34 which opens valves 30, 33 so that partially expanded steam flows from the first turbine stage 9 through the high pressure pre-heater 6a to the tank 4. The valve 32 is closed so that the pressure drop in the pipeline 18 leading to the low pressure pre-heater 3a is sensed by an impulse transmitter 41 which opens valves 36, 40 and closes a valve 38 so that the low pressure pre-heater 3a is fed by working medium tapped from a second turbine stage 10 the working medium flowing through pipes 35, 39 and a pre-heater 3 to return to the working medium cycle upstream of a low pressure pump 2.
