Abstract: 898,442. Cooling. EATON MANUFACTURING CO. Feb. 2, 1960 [May 11, 1959], No. 3745/60. Class 7(2). [Also in Group XXIX] A torque-transmitting device comprises a temperature-responsive valve 130 which controls the flow of fluid between a storage chamber 82 and an operating chamber between two relatively-rotatable members 42, 62, fluid within the operating chamber transmitting energy from one member to the other. The valve consists of an arm 130 which is movable to control an aperture 142 in a plate 80 between the operating chamber and the storage chamber by a spiral bi-metallic element 118 having one end engaged in a slot in a shaft 100, to which the arm 130 is secured, and its other end selectively engaged between projections 112 on a plate 110. The plate is located in any of a number of positions defined by notches 114 engaging projections 128 on a cover-plate 76. The engagement of the notches 114 with the projections 128, and the end of the element between adjacent pairs of projections 112 provides a coarse and fine adjustment for the element. The member 42 is provided with a groove 56 which is adjacent the aperture 142 in the plate 80 and connected by axial and radial passages 58 to a space between annular lands 48, 74 formed on the members 42, 62, respectively. The member 42 is driven by a pulley 14 from the crank-shaft of an engine and torque is transmitted by the shearing action of the fluid, such as silicone oil, between the lands to the member 62 connected to a cooling fan 68 for the engine. The amount of fluid between the lands is controlled by the position of the arm as determined by the temperature around the bi-metallic element. A tab 140 is formed on the leading side of the aperture 142 and extends into the channel 56 and, during rotation, forms a low pressure region at its rear side to assist in drawing fluid into the operating chamber; the tab also acts as a pump to force fluid in the channel through an outlet 144 which may be arranged to be closed by the valve arm. The member 62 is supported on the shaft 28 driving the member 42 by a simple bearing 32 and the fluid between the lands 48, 74 and in a space 75 between the members.

Title: Method of working up cellulose waste liquors containing sodium and sulphur
IPC: D21C11/12
Filed: 1962-02-02
Abstract: Cellulose waste liquors are worked up to recover sodium compounds as Na2CO3 and sulphur compounds as H2S by thermal decomposition of the liquor by bringing it together in a reactor with a concurrent stream of heated gas and separating the gaseous products from the other products, one portion of the gaseous products <PICT:0998467/C1/1> being subsequently heated indirectly by hot combustion gas whilst another portion is utilized as a component of the combustion gas. H2S in the gaseous products may be converted by combustion thereof to form SO2 either before or after removal from the gaseous products. In the specific embodiment, as shown, waste liquor is introduced into reactor 7 at 6 whilst hot gas previously heated in chamber 34 enters at 4. The reaction products leave reactor 7 at 8 and the solids are separated by cyclone 9, and passed to dissolving tank 29.  A portion of the heated gas leaving cyclone 9 is fed to the reactor 7 through pipe 35 whilst the remainder is used to preheat air passing along pipe 2 to combustion chamber 34.  H2S is removed from the gases at 18 by washing and the treated gas passed along line 19.  One portion 19a is used as combustion gas together with air 2 and if required, fuel oil 1, in combustion chamber 34 whilst the other portion 19b is heated by the hot gases.  H2S separated at 18 is passed to combustion chamber 24 where it is burnt with air 22 and if required, additional sulphur 23.  SO2 so formed is passed to vessel 26 where it is contacted with sodium carbonate solution coming from tank 29 after filtration at 32, thus forming sodium sulphite cooking liquor.  The use of an inclined reactor in the place of the vertical reactor is also mentioned. The reactor should preferably be run at below the ash fusion temperature e.g. less than 800 DEG  F.  The heated gas may be steam, CO2, CO, H2, N2 or mixtures thereof.
