Title: Manufacture of 2:3-aminonaphthoic acid
Filed: 1928-02-07
Abstract: 284,998. I. G. Farbenindustrie Akt.- Ges. Feb. 7, 1927, [Convention date]. 2 : 3-Aminonaphthoic acid is obtained by introducing 2 : 3-oxynaphthoic acid into melted zinc chloride-ammonia, or by introducing the latter in the molten condition into molten 2 : 3-oxynaphthoic acid. In this way the reaction mass remains molten when heat is applied and may be stirred. Zinc chlorideammonia having the formula. ZnCl2.NH3 is preferably used. In one example, the 2 : 3- oxynaphthoic acid is gradually introduced into the fused zinc chloride-ammonia, while in another the latter in the molten condition is fed into the molten 2 : 3-oxynaphthoic acid. Ammonia may be passed over the mass during the reactions The product is worked up by extracting it with hot hydrochloric acid after washing out the zinc chloride with more dilute cold hydrochloric acid. Caustic alkali or alkali carbonate is added in slight excess to the resulting hydrochloric acid solution, which is then boiled, cooled, and filtered. The 2 : 3-aminonaphthoic acid is precipitated on acidifying. The product of the fusion does not appear to be the hydrochloride of 2 : 3-aminonaphthoic acid; possibly it may be an internal salt or an amide.

Abstract: 1439896 Removing mercury from gases PATRONATO DE INVESTIGACION CIENTIFICA Y TECNICA JUAN DE LA CIERVA DEL CONSETO SUPERIOR DE INVESTIGACIONES CIENTIFICAS 29 Jan 1974 [29 Jan 1973] 04173/74 Heading C1A The vapour of mercury and its compounds is removed from metallurgical off-gases which also contain SO 2 , by passing through acidified aqueous solutions of thiocyanates, the SO 2  oxidizing the mercury to a form in which it can be complexed by the thiocyanate. If necessary, sufficient additional SO 2  can be added to the effluent gases to effect the oxidation. The lower limits for the acid and thiocyanate concentrations are both 2 g./l., while the upper limit is established merely by the stability of the resulting solution. The temperature range of the process is that of liquid water at ambient pressures. The mercury concentration in the gas may range from 5 mg./m.<SP>3</SP> to 20 g./m.<SP>3</SP>. In one example, gases containing 6% of SO 2  and 8-1000 mg./m.<SP>3</SP> of mercury were washed in a 3-metre column containing Raschig rings with a solution containing 60 g./l. of H 2 SO 4  and 150 g./l. of potassium thiocyanate ; the washed gases contained less than 5 mg./m.<SP>3</SP> of mercury.

Title: Improvements in or relating to control means for variable jet-nozzles of jet propulsion and gas-turbine systems
IPC: F02K1/15
Filed: 1945-02-20
Abstract: 588,502. Gas turbines. PEREGRINE, E. P. Feb. 20, 1945, No. 4316. [Class 110 (iii)] [Also in Groups XXXV and XXXVII] A system for varying the area of a jet nozzle in a jet-propulsion or gas-turbine system comprises a reversible electric motor coupled through a detachable connection to the moving parts of the nozzle and a control switch arranged to energize the motor in either direction and to control electrical release means for the detachable connection. Fig. 1 shows a reversible motor 11 which drives gear 9 through a detachable connection, cable 10 and chain 8 to vary the position of jaws 6. When the switch 29 engages contact 30a, motor 11 drives in a direction to close the jaws, either until the movement is stopped by returning switch 29 to blank position 30b or until the jaws reach a limiting position and limit switch 26 opens. The motor drives in the opposite direction when contact 30d is engaged, limit switch 27 being operated to stop the motor. To adjust the nozzle automatically in accordance with changes of temperature, the switch is set on contact 30c. Two-way switch 28 is operated by thermostat 29 due to changes of temperature, thus closing either of solenoid-controlled switches 32, 33 to drive the motor.in one clirection or the other. When the temperature returns to its original value due to opening or closure of the jaws, switch 28 opens and the motor stops. The detachable connection comprises a piston 24 having a notch or shoulder which is normally latched by spring-pressed latch 17, so that the piston 24 and cylinder 16 move together. When the switch engages contact 30e, solenoid 20 is energized to release the latch so that the cylinder moves forward rapidly under the internal gas pressure to open the jaws completely, the rate of movement only being limited by the dashpot action of piston 24 in cylinder 16 so as to minimize shocks. A circuit is also completed through contact 30d to energize the motor and drive piston 24 to follow up the latch plate so that it is in a position to be re-latched when solenoid 20 is de-energized. Specification 588,501 is referred to.

In a motor vehicle a hot air supply conduit comprises two branching passages leading respectively to the carburetter and to the interior of the vehicle, a tube open to atmosphere joining the branching passage connected to the carburetter and means is provided for controlling the respective flow rates of fresh air and of hot air to the carburetter at the junction of the tube and of the branching passage so that the temperature of the air flowing into the carburetter can be controlled independently of the temperature of the air flowing into the interior of the vehicle. Air from an intake 7 is heated by a coil 9 through which flows a stream of hot fluid such as the exhaust gases or as shown water from the cooling system a fan 6 placing the air under pressure. The fan and heater belong to the vehicle heating system pipe 10 leading to the inside of the vehicle. The fan is driven by an electric motor fed from the battery of the vehicle. In hot weather the circulation of hot fluid through the heater is stopped or the operation of the fan 6 is stopped. A valve 12 controlling the flow of air may be manually operated but is preferably actuated by a thermosensitive device 14 responsive to the surrounding temperature. All fresh air may be cut off as soon as the temperature drops below - 5‹C. Suction acts against resilient means which may be the strip 14 itself to open the passage 4 if the fan is not working. In a modification the outlet of pipe 5 is controlled by a sliding valve actuated by a thermosensitive device subjected to the temperature of the mixture fed to the engine. The air filter is indicated at 3.

In Fig. 1, the section apertures 16 are formed in a thin plate 12 let into the working surface of the board 10 and reciprocated by an oscillating lever 14 on a hollow shaft 15 connected by a tube 18 to an aperture 17 in the board 10 over which the apertures 16 in the plate 12 passes. Preferably, two plates 12 are used and the suction is continued until the apertures 16 pass the stops 11 when the suction is cut off gradually. The plate 12 may be arranged on top of the board 10 and be reciprocated by a rack and pinion. In a modification, Fig. 4, the suction apertures 42 are arranged in a roller 40 and act in succession as these pass the suction port 45 arranged inside the roller 40.
