Abstract: In a gas-bubble brick of refractory ceramic material, the visual detectability of a worn state is improved. The detectability should be independent of the material of the gas-bubble brick. For this purpose, a gas-permeable distance space 3, which has a different geometrical shape in the direction of wear, extends in the gas-bubble brick. As a result, a different pattern corresponding to the state of wear is visible on the surface of the gas-bubble brick when gas flows through the distance space 3.

Abstract: 1472166 Two stage SO 3  contact process SUD-CHEMIE AG 12 Jan 1976 [12 Feb 1975] 01020/76 Heading ClA Concentrated sulphuric acid or oleum is obtained by the catalytic oxidation in two stages of SO 2  to SO 3  starting from a gas stream containing water vapour in addition to oxygen, SO 2  and inert gases, the SO 2  is partially oxidized in a primary catalyst stage after which the gas stream is cooled, substantially all of the water vapour and the SO 3  formed are absorbed in sulphuric acid; the unreacted SO 2  is then oxidized over a secondary catalyst substantially in the absence of water vapour and the SO 3  formed in this second stage is finally absorbed in sulphuric acid. The cooling, water vapour absorption and SO 3  absorption after the first stage are preferably carried out in separate units. In the figure the reaction gas is fed into a multi-stage primary catalyst system 10 through line 1, between the individual stages of this primary catalyst system the gas stream is cooled in heat exchangers 2 and 3 which are used to generate steam, the gas rich in SO 3  passes out via heat exchangers 5 and 7 into the cooling unit 20 where 96-99% H 2 SO 4  is fed through line 21; in the water vapour absorption unit the water is absorbed by contact with cold H 2 SO 4  from line 31, the gas stream then passes through the SO 3  absorber 40, via line 33, and the SO 3  removed by washing with 99% H 2 SO 4  from line 41. The gas stream now containing SO 2  and O 2  passes via line 42 to a secondary multi-stage catalyst system 50 and from here the SO 3  passes through line 51 to the final absorber_60 fed with sulphuric acid through line 61.

Title: Reduction of sulphur dyes
IPC: D06P1/30
Filed: 1964-01-09
Abstract: The invention comprises a process for the reduction of sulphur dyes in which an alkali metal borohydride is used in conjunction with sodium sulphide or hydrosulphide in alkaline solution.  The reduction may be effected using dyes which are soluble or insoluble in water to produce a dye composition in the liquid form.  Alternatively the dyestuff may be reduced to the substantive form in the presence of a cellulosic material to be dyed.  The preferred borohydrides are those of sodium and potassium and are used as 0.01% to 1% preferably 0.1 to 0.6% based on the weight of sulphur dye to be reduced.  The temperature of reduction is from room temperature to 230 DEG F. at pH usually above 9.5.

Title: Improvements in the treatment of cellulose derivative filaments, yarns and the like
IPC: D01F2/28
Filed: 1937-01-13
Abstract: Artificial filaments, yarns, and the like made of organic derivatives of cellulose are passed through a body of water under super-atmospheric pressure in an end pressure chamber and in substantially non-slipping contact with a driven feed device contained in the chamber and then through saturated or wet steam at a temperature above 100 DEG  C. in a steam chamber, and stretching the materials during their passage through the steam chamber. Preferably, the temperature of the steam is at least 130 DEG  C. and that of the water not greater than 30 DEG  C.  The properties of the materials, particularly their tenacity and extensibility, may be varied by varying the temperature of the steam, the relation between the pressure of the steam and the pressure of the water, the degree of stretch, the size and number of the steam inlets, and the length of the steam chamber.  Specification 443,707 is referred to.

Abstract: 900,329. Determining relative quantities of fluid mixture constituents. LEEDS & NORTHUP CO. Jan. 10, 1961 [Jan. 15, 1960], No. 1051/61. Class 37. In an arrangement for measuring the conductivity of liquid in a cell 12 which is connected in series with a resistance 20 and energized by the output from a voltage regulated transformer 13 connected to an A.C. source 9, the potential across resistance 20 is applied over a transformer 25 to a transistor demodulator 27 energized also from the source 9. Temperature compensation is provided by a resistance 22 having a large negative temperature coefficient and immersed in the solution, or by a potentiometer which may be set manually according to the solution temperature. The supply from the power source to the demodulator is converted to flat-topped switching pulses by diodes 33a, 33b, and the output from terminals 38a, 38b is a direct current which is a function of the conductance. Meter 41 may include manually adjustable contacts 44 for controlling an alarm circuit, and its zero may be adjusted by a resistor 60. A recorder 58 may be connected across a series resistor 57. A meter construction, described with reference to Fig. 3 (not shown), may have provision for receiving the alarm circuit as a plug-in unit. Values of components are given and include the values of resistor 20 for measuring a number of ranges.

Abstract: 157,209. Hammond, J. H., (Assignee of Chaffee, E. L.). April 25, 1918, [Convention date]. Undesired signals, limiting; thermionic valves, arrangements of.-The detector of a receiving system is shunted by a " by-pass " device comprising a number of thermionic valves, adapted to protect it from interfering high potential effects of either polarity or of a given polarity. In the arrangement shown in Fig. 1, the device 49 is connected across the tuning condenser 33 oi a valve detector circuit, and comprises two pairs of valves 50, 51 and 52, 53, similarly arranged with respect to one another but conductive in opposite directions with respect to the terminals 68, 69. The valves 50, 52 are adjusted to produce a saturation current and, acting alone, have a characteristic as shown in Fig. 2. The valves 51, 53 have the characteristic 95, Fig. 3. The combined curve for the two valves 50, 51 is represented by the curve 105, Fig. 5, and that for the valves 52, 53 by the line 106. The slopes may be made steeper by adjustment of the resistances 77 and batteries 75. If both pairs of valves are operated simultaneously the resultant characteristic is represented by the dotted line 115, Fig. 7, and if a resistance 70, having a characteristic 116, be inserted as shown in Fig. 1, the resultant will have the form 120. From the resultant curve 120 it is evident that for potential fluctuations of about one-tenth of a volt on either side of zero, no current will flow through the device 49, but for potential variations greater than this a relatively large current will flow and the effective resistance of the device is reduced. By steepening the curve 115 a resultant curve 125, Fig. 8, may be produced, indicating a negative resistance characteristic for small voltage fluctuations. Such a curve implies an amplification of weak signals by the device 49. In a modification, a potentiometer is inserted between the terminal 68 and resistance 70. The resultant curve 142 is shown in Fig. 10, the characteristics of the valves, and the resistance plus the potentiometer, being represented by the dotted curves 140, 141 respectively. According to another modification; Fig. 11, the resistance 70, Fig. 1, is omitted and two oppositely arranged valves 150, 151 are substituted. Batteries 155, 156 impress a positive potential on the grids of the valves 150, 151, and also serve as plate batteries for the valves 50, 52. The characteristic of the valves 150, 151, according to the adjustment of the potentiometers, may take the form 175, 176, or 177, Fig. 13, one of which substituted in place of the resistance curve 116, Fig. 7, will produce a resultant similar to the curve 120, Fig. 7, or to the curve 125, Fig. 8.
