Granted: 1956-01-05
Abstract: A process for the continuous production of a propyl nitrate comprises keeping an aqueous reaction solution containing per 100 parts thereof between 30 and 45 parts nitric acid, at least 3 parts urea, and between 10 and 31.5 parts ammonium nitrate, all by weight, at a temperature between 105 DEG  and 112 DEG  C. (preferably 107-110 DEG C.) at atmospheric pressure, while maintaining this composition and the bulk by continuously introducing under the surface of the reaction solution nitric acid, the appropriate propyl alcohol, water and urea, at least the continuously added nitric acid and said propyl alcohol being introduced in separate streams, if desired already diluted with at least part of the continuously added water, at rates such that the molar ratio of added nitric acid to said propyl alcohol exceeds unity, and the continuously added urea being introduced in solution in at least one of the liquids streaming into the solution, continuously distilling away and condensing the resulting vapour mixture containing the propyl nitrate formed, continuously bleeding off a portion of the aqueous reaction solution of said composition, and separating the propyl nitrate rich layer of the condensate from the water rich layer.

Title: Waste water treatment settling tank
IPC: C02F3/12
Filed: 1968-05-20
Granted: 1971-03-22
Abstract: The settling tank consists of a large square tank with inclined walls. The tank, made of any suitable material, is divided into different compartments. Two thickening compartments, on the inlet side, act as a grease box and the effluent then passes through a grinding grid, fitted with a motor-driven rake, on its way to the oxidation compartment. Two faces of the tank are connected by a foot-bridge on which a device is mounted for introducing the necessary air into the mass of water undergoing treatment in this chamber. The latter acts both as an activating tank and as a primary settlement tankf a hydrostatic suction device allows the sludge to be evacuated from the thickening compartment for pumping to a drying bed. The resulting water has properties superior to Public Health authority requirements.

Patent GB-1044109-A (GB)
Abstract: 1,044,109. Ignition and control of burners. WHIRLPOOL CORPORATION. July 29, 1965 [Oct. 26, 1964], No. 32526/65. Headings F4F and F4T. A safety control system for the gas burner 11 of a clothes dryer comprises a silicon controlled rectifier 52 controlling a solenoid gas valve 30 and arc electrodes 40, 41 for igniting the burner. The S.C.R. 52 is triggered by a voltage divider network including a resistance 56 which heats a bi-metal switch 26 adapted to de-energize the complete system. In operation when the A.C. power 13, 14 is closed by a switch 16 actuated by a timing motor 15, a capacitor 47 is charged and the voltage at point 59 of the divider network increases during a positive half-cycle until it triggers the S.C.R. 52. The capacitor therefore discharges through the S.C.R. and energizes an ignition transformer 43 connected to the arc electrodes 40, 41. The S.C.R. also energizes the solenoid valve which therefore opens. During the negative half-cycles current through a by-pass resistance 65 is sufficient to hold the valve in open position. If the burner ignites on thermistors 60 having a negative coefficient of resistance or a bi-metallic thermostat or a light-sensitive cell responds to the flame and alters the distributer of voltage on the divider network so that the point 59 is no longer able to trigger the S.C.R. If ignition is unsuccessful the heater 56 eventually opens the bi-metal switch 26. A second solenoid valve 31 in parallel with valve 30 acts as a safety device. Motor 24 drives a rotatable drum used in the clothes dryer. In a modification, Fig. 2 (not shown), the solenoid gas valve 30a is operated by D.C. pulses and consequently a diode 81 is inserted in series with the by-pass resistance 65. The flame is detected by a thermistor 80 having a positive coefficient of resistance connected in series with the resistances in the divider network. In a further modification, Fig. 3 (not shown), the heating resistance 56 for the bi-metallic switch 26 is in series with a second S.C.R. 86 which is triggered by a diode 88 and capacitor 89, and which triggers the S.C.R. 52 for energizing the gas valve 30 and the arc igniters 40, 41. If ignition is unsuccessful the second S.C.R. 86 continues to be triggered and eventually the resistor 56 heats up sufficiently to open switch 26. The valve 30 may comprise two individually wound coils 32a and 32b, Fig. 7 (not shown). Upon closure of switch 16 holding coil 32a is energized through resistance 65 and pull-in coil 32b energized through the S.C.R. 52 as described above. Upon ignition of the fuel when the S.C.R. is rendered non-conductive the current flow through coil 32b is terminated and the valve maintained open by the holding coil 32a.

Abstract: 1,051,216. Ethylene glycol terephthalate. METALLGESELLSCHAFT A.G. March 4, 1964 [March 6, 1963], No. 9228/64. Heading C2C. In a process for the preparation of an ethylene glycol terephthalate from o-phthalic acid, the latter is converted into di-potassium-o-phthalate (K 2 P) which is thermally transposed to dipotassium-terephthalate (K 2 T) and mono-potassium terephthalate (KHT) is precipitated from the aqueous solution of K 2 T, and wherein the KHT is reacted, if desired in the presence of phthalic acid (H 2 T), in aqueous suspension with ethylene oxide to form the K-salt of monoethylene glycol terephthalate, from which the free ester is formed by a further reaction with free o-phthalic acid or its anhydride (and water) and/or terephthalic acid, and the potassium salt forming in these conditions is returned to the KHT production stage of the process. The KHT may be precipitated by reacting the K 2 T with carbon dioxide and after reacting it with ethylene oxide to form the potassium salt of monoethylene glycol terephthalate from which the monoester is precipitated by o-phthalic acid or its anhydride, the mixture of KHP and free o-phthalic acid forming in these conditions is then reacted with the KHCO 3  obtained from the precipitation of the KHT, to give a mixture of K 2 P. KHP and free carbon dioxide, the latter being returned to the KHT precipitation stage and the mixture of K 2 P and KHP being converted, with evaporation, to a mixture of K 2 P and free o-phthalic acid, which latter after distillation is returned to the monoglycol terephthalate K-salt reaction, and the K 2 P being thermally transposed in manner known per se to form K 2 T. The reaction of K 2 T with carbon dioxide may be such as to give a mixture of KHT and H 2 T in addition to KHCO 3 , the latter is reacted with free o-phthalic acid or its anhydride to form K 2 P and carbon dioxide, the K 2 P is thermally transposed to form K 2 T and the carbon dioxide is returned to the KHT precipitation, and the mixture of KHT and H 2 T is reacted with ethylene oxide to give a mixture of glycol esters of terephthalic acid and K 2 T, which latter is returned to the KHT precipitation. A mixture of mono- and diethyleneglycol terephthalates may be produced and the ratio of these two esters in the mixture is so adjusted by controlling the precipitation conditions of the KHT with carbon dioxide, that KHT and free H 2 T are precipitated during this precipitation in the ratio required for the desired relative proportions of the mono- and diethyleneglycol terephthalate in the mixture. Examples are described of a preparation of the pure mono- and the diesters and of a mixture of the two with the help of flow sheet diagrams.
