Title: Process of calcining finely divided solids
IPC: C22B1/10
Filed: 1953-05-26
Abstract: <PICT:0745552/III/1> In the calcination of finely - divided solids of the type that evolve gas or vapour at a treament temperature lower than that of the final treatment, two successive beds of finely-divided solids are formed and maintained in a fluidized condition by upwardly passing gas streams successively through the beds and by maintaining the first of such beds at a temperature sufficient to evolve gas or vapour by insufficient to complete the treatment while maintaining the second bed at a higher temperature necessary for complete treatment but below the fusion point of the bed solids, transferring the partially treated solids from the first bed to which the solids for treatment are fed, to the second bed for completion of the treatment and maintaining the desired temperatures in the first and second beds by supplying regulated quantities of fuel directly into both the beds and combusting it there to liberate heat.  The process is particularly applicable to calcination of hydrated aluminium oxide which gives up its water vapour at about 600 DEG C. but which requires a final calcination temperature of about 1100 DEG C. to yield anhydrous alumina.  Another example is copperas, which gives up its water at low temperatures, but requires a higher temperature to decompose it into iron oxide and sulphur dioxide.  As shown in the Figure, a reactor 35 is made up of four superposed fluidized beds 58, 55, 53 and 50 fluidized by gas entering through pipes 22; the upper bed 50 acts as a preheating bed and the lower bed 58 acts as a cooling zone. Solids are fed either to the preheating bed through a pipe 45 or by pipe 46 to the low temperature calcining bed 53 from which they flow through a downcomer to the lower fluidized bed where the final treatment is effected.  Fuel is supplied to the low temperature and high temperature treatment beds through pipes 60, 61, and 62, 63 respectively and in addition a further fuel injection pipe 24 is provided for initial start up after which fuel pipe 24 is closed.  A discharge 70 is provided from the lowermost cooling bed, for the final product and clean-out ports 71 to 74 are provided for each bed.

Patent GB-1494369-A (GB)
Title: Current amplifier
IPC: H03F3/343
Filed: 1975-04-10
Abstract: 1494369 Current amplifiers RCA CORPORATION 10 April 1975 [15 April 1974] 14747/75 Heading H3T In a current amplifier 10, Fig. 1, the voltage drops across a first resistance element 115 caused by input current at 106 is compared with that across a second resistance element 116 caused by the output current to terminal 107 by a differential amplifier, the output of which controls a transistor 114 to keep the current constant. If elements 115 and 116 are identical the amplifier has unity gain. Other gains may be achieved by proportioning the junction areas of the diodes in resistance elements 115 and 116 and transistors 118, 119. The transistors may be composite transistors, e.g. the Darling- ton pair 114, 120 or may be field effect transistors. As shown the amplifier is used to convert a pushpull input 103, 104 to a single ended output at 105. The resistance of 123 is chosen so that the current through it equals the sum of the collector currents of 118 and 119, but the amplification of 118 and 119 may be increased by choosing 123 to provide a substantially greater current, the surplus being taken up by a current mirror connected between the collectors of transistors 118 and 119, Fig. 2 (not shown). Some or all the diodes 110-113 may be diode connected transistors and resistor 123 is replaced by a diode or diode connected transistor. Resistor 123 may alternatively be replaced by one or two transistors biased from the junctions of diodes 110, 111 and 112, 113, to provide a current that depends upon the input and output current of the amplifier. The transistors may be biased by a constant current source if a current independent of the input and output currents is required. Emitter resistors may be provided for the transistors replacing resistor 123 to make component matching less critical, Fig. 5 (not shown). The amplifier output impedance may be lowered by a further transistor connected in cascade between the collector 102 and the output 105, Fig. 4 (not shown). Diodes 111, 113 may be combined as a single diode connected transistor, Fig. 6 (not shown). The diodes 110, 111 and 112, 113 may be augmented or replaced by the collector-emitter paths of transistors, Figs. 7, 8 (not shown). In another embodiment, Fig. 10, the differential amplifier comprises NPN transistors 118<SP>1</SP>, 119<SP>1</SP> the quiescent conditions of which are established by transistors 202<SP>1</SP>and 32 by mirroring of the current in the series chain 11-17. The voltage drops across elements 115 and 116 are coupled to the bases of transistors 118<SP>1</SP>, 119<SP>1</SP> through networks 40, 50 which ensure that the collector-base junction of transistor 118' is not forward biased.

Title: Manufacture of trisazo-dyestuffs
IPC: C09B31/16
Filed: 1951-06-21
Abstract: The invention comprises trisazo dyestuffs of the formula R1-N=N-R2-N=N-R3-N=N-R4 where R1 is a heterocyclic residue containing a 5-membered hetero-ring which contains at least two hetero atoms of which at least one is nitrogen bound exclusively in the ring, R2 is a benzene or naphthalene residue, R3 is a 5-naphthol-7-sulphonic acid residue bound to -R2-N=N- in the 6-position and to -N=N-R4 in position 1 or 2 directly or via a bridge member, and R4 is the residue of a coupling component which is itself capable of forming metal complexes.  In preferred compounds R1 is a benzene residue in which two carbon atoms also form part of a 5-membered ring containing 2 or 3 nitrogen atoms, R2 contains a metallizable group oto -N=N-R3-and R4 is an 8-oxyquinoline residue.  The trisazo dyestuffs are made by coupling a diazotized amine R1NH2 with a middle component H-R2-NH2, diazotizing the product, coupling in alkaline medium with H-R3-NH2, again diazotizing and coupling with HR4.  Preferably R1 is free from hydroxyl groups.  The middle component H-R2-NH2 may be coupled in the form of its sulphomethyl derivative and subsequently hydrolysed.  The final coupling may take place in the presence of an alkaline earth hydroxide and/or pyridine.  The trisazo dyestuffs are suitable for dyeing and printing wool, silk, leather, cotton, linen and regenerated cellulose.  They may be metallized (e.g. coppered) on the fibre or in the dyebath, e.g. by the process of Specification 455,274 or 619,969.  In the examples, the following dyestuffs are prepared: (1) 6-aminoindazole --> cresidine --> N - (41 - amino - 31 - sulphophenyl) - J acid --> 8 - oxyquinoline; (2) 2 - methyl - 6 - amino - benzimidazole --> cresidine and other components as in (1); (3) 6-aminobenztriazole --> cresidine &c. as in (1); (4) 6-aminobenzthiazole --> cresidine &c. as in (1).  A further example shows the dyeing of cotton navy blue with the dyestuff of (1) coppered in the dyebath.  A list of further dyestuffs and components therefor is given, including the following additional types: R1 a triazole, thiazole, naphthimidazole or phenylbenzimidazole nucleus, R3 a naphthalene, phenyl-naphthyl-urea, phenyl-naphthimidazole or phenylnaphthothiazole nucleus, and R4 a salicylic acid residue.  When R2 contains a hydroxy group, diazotized R1NH2 is coupled with o-acetylaminophenol in alkaline medium and the product hydrolysed.

Title: Arrangement in centrifugal separators for maintaining a uniform flow of liquid in the supply and/or discharge pipes
IPC: B04B11/02
Filed: 1937-05-31
Abstract: 474,017. Centrifugal separators. AKTIEBOLAGET SEPARATOR. May 31, 1937, Nos. 15066 and 15067. Convention dates, June 10, 1936 and Aug. 27, 1936. [Class 23] The flow of liquid through one or more of the supply or discharge pipes of a centrifugal separator is kept constant by a regulating valve in the pipe, the operation of the valve being dependent on the drop of pressure between two points in the pipe. The pipe 1, Fig. 1, may be the cream pipe of a separator and has a throttle 2 through which the fluid passes from right to left. The spaces 3, 4 on each side of the throttle are connected by pipes 5, 8 to a cylinder 6 containing a piston 7 which supports a valve body 10 by which the pipe 1 can be partly shut off. The weight of the piston and valve is counterbalanced by the difference of pressure in the spaces 3, 4, so that when the pressure varies the valve 10 is moved to keep the difference of pressure constant and the flow in the pipe 1 therefore remains uniform. Loose weights 13 may be carried on a holder 12 supported from the piston 7 for purposes of adjustment. In a modification, the throttle 2 and pipes 5, 8 are connected to one of the discharge pipes from a centrifuge and the valve body 10 is situated in the other. A construction of regulator suitable for insertion in a pipe from a centrifuge which discharges two liquids by paring members is shown in Fig. 3. A piston 16 works in the chamber 15 and is controlled by a spring 18 arranged between its spindle 17 and the adjustable screw 19. The valve body 21 on the piston is shaped so that the available cross-section of the opening 22 is reduced as the spring is compressed. The chamber 23 is connected to the chamber 15 by a channel 24 containing an adjustable throttle 25. The liquid flows from the chamber 23 through the channel 24 to the chambers 15 and 26. Owing to difference of pressure between the chambers 23, 15 the piston is moved to compress the spring and the diminution of the space 22 by the valve body 21 causes the pressure in chamber 15 to rise to keep a constant difference dependent on the strength of the spring. A loaded lever may be. used as a substitute for the spring.

Abstract: 713,953. Delivering measured quantities of liquids, THACKRAY, Ltd., C. F. June 19, 1952 [June 27, 1951]. No. 15243/51. Class 106(5) [Also in Group VI] Apparatus for delivering measured quantities or a constant flow of warm sterile water for surgical operations comprises a measuring chamber 11, a control valve 15 and a discharge valve 25, the chamber being connected by a pipe 7 to a hot and cold water circulating system through a thermostatically-controlled mixing valve 3. Both valves 15 and 25 are opened when a continuous flow is required and the water passes through a port 17 in a disc 13 on the valve spindle 12 and through an outlet tube 20 into a discharge pipe 23. If the discharge valve is closed, the water fills the chamber and then passes out through a tube 26, a port 29 in another disc 14 on the valve spindle and a pipe 8 back to the circulation system, the constant circulation into and out of the system preventing the water from cooling off in the chamber. By rotating the spindle 12 to close the ports 17 and 29, the circulation is cut off and the contents of the chamber, down to the level of the discharge pipe 23, can be drained off by opening the discharge valve. An air inlet and outlet passage 36 is controlled by the valve disc 14 or by a float valve 37 to which an air filter 38 is fitted. The discharge pipe 23 may be slidably adjustable and be protected against contamination by a bellows 39 of stainless steel or other material. A float-type non-return valve 40 is fitted on the lower end of the discharge pipe and the head of the pipe carries an indicator 35 which shows the adjusted capacity of the chamber against graduations on the glass sleeve 21. The apparatus may be suspended from a ball joint 41.
