Title: Reactor and process for the evaporation of liquids
IPC: B01J8/16
Filed: 1972-01-24
Abstract: 1368022 Evaporators; recovery of iron oxide from acid pickle liquors; gas filter ENVIRONMENTAL TECHNOLOGY Inc 24 Jan 1972 [25 Jan 1971 29 July 1971] 3216/72 Heading C1A [Also in Division B1] Iron oxide is obtained from an acid solution of iron sulphate or iron chloride, e.g. acid pickle liquor, by distributing through nozzle 108 and/or duet 112 on to a compact bed of inert solid particles (e.g. an iron oxide mill scale) moving down the inclined floor 20 of refractory-lined chamber 12 while hot gases from burner 14 pass upwards over the bed, evaporating water and free acid and oxidizing the iron salt to iron oxide. The solids leave the lower end of the chamber through duct 78, and may be submitted to delumping (Fig. 4, not shown) before being recirculated to hopper 98. The floor 20 of the chamber is layered; and I-beams 34 support a honeycombed layer 42 of stainless steel on which is mounted platform 44 having spaced ribs (Fig. 3, not shown). The floor may be vibrated by vibrator 116. The inclination of the chamber can be adjusted by screw jack 28. The depth of the compact bed on platform 44 is preferably 1 to 4 inches. By adjusting the position of nozzle 108, the feed liquor may have sufficient contact with the hot gases to undergo concentration by evaporation before it contacts the compact bed. The gases leave the upper end of the chamber through outlet 16 containing steel-mesh filter basket 86 which is shaken by vibrator 84. The hot effluent gases may be contacted with fresh feed liquor to preheat it, and may then be contacted with water for acid recovery. Basket 86 may include a catalyst, e.g. V2O5 for the conversion of SO2 to SO3. The specification also refers to the treatment of municipal sewage and waste liquors from the paper and cellulose industries. In these applications, sand or carbon may be used for the compact bed.

Abstract: 597,940. Magnetic and electric tests. STANDARD TELEPHONES & CABLES, Ltd. Feb. 9, 1945, No. 3288. Convention date, Feb. 26, 1944. [Class 37] Electrical properties of materials are investigated by insertion of specimens of the material in the tank circuit of an oscillator the output of which is connected to a cathode-ray indicating device. In Fig. 1, valves 1 and 2 are connected to form an oscillator which is energized by pulses applied to the grid of valve 1 through lead 15. The output of the oscillator is connected to the vertical and horizontal plates of an oscillograph 0 through a phase-splitting circuit, resistance 22 and capacitor 23, and a signal S is applied to the grid through lead 26 to provide blanking of the beam. Metal specimens are inserted in coil 17, dielectric specimens in capacitor 16 and patterns such as those shown in Fig. 4 appear on the oscillograph screen 30. Measurement of the electrical characteristics of the materials is given by observing the adjustments required to return the patterns to their original shape by means of calibrated capacitor 16a and resistor 18. Alternatively, the tank circuit containing the specimen is disconnected from lead 15, the standard circuit 16<1>-17<1>-18<1> connected in its place, the circuit variables adjusted to give the same pattern as the test circuit and the characteristics of the material under test read from the dial calibrations.

Abstract: 447,304. Vehicle hoods. OVERTON, W., 10, Marsh Street, Walsall. Feb. 4, 1935, Nos. 3502 and 28182. [Class 108 (i)] In vehicle hoods of the kind in which the hood sticks of the flexible cover are carried by links pivoted to longitudinally guided carriage members, the links are provided with means which cause them to fold and unfold in succession. The hood sticks 3 are attached to plates 4 by screws and the plates 4 are pivoted to members 5 by pin-and-slot means the members 5 being pivoted by rods 9 in the hinge members 8 of adjacent links 10, 11. The other ends of the links 10, 11 are pivoted at 20 to slidable carriages 12 and have secured to them tail pieces 17, 18. The interaction of the tail pieces 17, 18 is shown in Figs. 5 to 8. Inunfolding or extending rotation into horizontal position of the leading link 10 of a pair causes its tail piece 17 to ride along the tail piece 18 of the trailing link 11 and ultimately clear it so that the latter link is free to turn. In reverse or folding order the link 11 becomes the leading link and rotates into vertical position its tail piece 18 ultimately freeing the tail piece 17 of the link 10 and a projection 29 on the link 11 when the latter reaches its folded position tripping a projection 28 on the link 10 to cause the hinge 8 of that link with the next adjacent link 11 to be broken to permit folding. The carriages 12 are moved by a chain 14, and sprocket gear 16 from a handle or motor.

Abstract: 660,380. Softening water. CZECHOSLOVAK METAL & ENGINEERING WORKS, NATIONAL CORPORATION. Feb. 9, 1949 [Feb. 9, 1948], No. 3549/49. Class 46 In regenerating the mass of baseexchange material in a water softening apparatus by introducing a regenerative solution into the mass, the layer of the material which has been fully exhausted during a water - softening operation is regenerated separately from the layer of the material which has been only partially exhausted during the softening operation. The regenerative solution is introduced into the material in the same direction of water flow as during the water softening operation and is taken out of the mass of the material at a point between the inlet and outlet of the water until the layer of material above this point has been regenerated whereupon the regenerative solution is taken out at the said outlet so that it flows through the lower only partially exhausted layer of the material. To this end, as shown, at least one permeable partition 13 is mounted so as to intersect the path of flow of the water between the inlet 10 and outlet 11 of the tank 9 containing the base-exchange material 5<SP>1</SP> and 7' and the partition 13 contains perforated heads 15 associated with conduits for collecting and conducting the regenerative liquid away through a valve 16 and conduit 17. When the upper laver 7<SP>1</SP> of the material has been regenerated, the valve 16 is closed and the regenerative liquid flowed through the lower laver 5<SP>1</SP> to regenerate this layer, the liquid being conducted away through the outlet valve 18. The position of the partition above the water collecting space 12 is equal to the depth of the partly exhausted material layer 5<SP>1</SP> under the operational conditions of the apparatus and measured in the direction of flow of the softened water.
