Abstract: 879,856. Storing and transporting liquefied gases. CARTER, G. O. Aug. 6, 1957, No. 24769/57. Class 8(2). Liquefied natural gas is charged into heat insulated storage tanks of a transport vessel 10 and at its destination the tanks are discharged into shore tanks 12 from which it passes in heat exchange with air to be rectified in a unit 17 from which liquid nitrogen is fed through a duct 19 into tanks 20 and into the transport vessel tanks to replace the liquefied natural gas and thereby serves to maintain the temperature thereof at a low value. At the end of the return journey the liquid nitrogen serves to provide cold for the liquefaction of the natural gas.

Filed: 1923-10-05
Abstract: 228,592. Wade, H., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Oct. 5, 1923. R÷ntgen-ray tubes.-An incandescent-cathode R÷ntgen-ray tube has a gaseous filling of hydrogen or helium, or a mixture of these gases, under a pressure above 0.0006 millimetres of mercury but below that at which objectionable gas ionization occurs, and the construction and geometric dimensions of the tube are such that the field adjacent to the focal spot is much intensified on supplying the high voltage. The tube shown in Fig. 1 has an anticathode 3, and a glow cathode 2 which is surrounded by a focusing device 5 consisting of a metal cylinder to which a metal hemispherical element is fixed. The anticathode may be of tungsten fixed in copper and is so arranged that the cathode rays can strike it over part of its surface only. The tube may have a hydrogen filling at a pressure between 0.01 mm. and 0.03 mm. of mercury, or higher, and the distance from cathode to anticathode may be only 0.8 centimetres, so that when connected to 100,000 volts a very intensive field is obtained before the anticathode. A tube with a metal envelope is shown in Fig. 2. In this construction, the glow cathode is arranged within a metal vessel 7, and a metal diaphragm 8 provided with an aperture is positioned in front of part of the surface of the anticathode 10. The vessel 7 is provided with a window for the passage of the R÷ntgen-rays. The window consists of a glass cap 11 sealed to the vessel, an annular plate 12 of iron being fitted inside the tube to protect the joint 19 from being struck by the cathode rays. Another plate 16 protects the joint 15 between the metal body 7 and the upper part of the tube. The tube is filled with hydrogen or helium at a pressure of 0.01 to 0.03 mm. of mercury.

Title: Method for the purification of n,n-dimethylacetamide
IPC: C07C233/00
Filed: 1957-08-09
Abstract: N : N-dimethylacetamide is separated from a mixture containing it and acetic acid by adding chlorobenzene, toluene, ethylbenzene, or xylene to the mixture, heating the resultant mixture to a temperature sufficient to vaporize and thereby remove the azeotrope of acetic acid and substituted benzene and recovering the N : N-dimethylacetamide from the residue.  Preferably enough of the substituted benzene is added to enable all of the acetic acid to be distilled off, alternatively less of the substituted benzene may be used and as a result the N : N-dimethylacetamide contains on distillation a proportion of acetic acid which may be removed if required by the addition of further substituted benzene and azeotropic distillation.  In a typical example (No. 1) 500 grams of a mixture of N : N-dimethylacetamide and acetic acid containing 29.6 per cent of the latter was mixed with 400 grams of ethylbenzene and a distillate removed until a head temperature of 128 DEG  C. was obtained.  An additional 466 grams of ethylbenzene was then added continuously.  By distilling the residue at 85-86 DEG  C. and under 50 mms. mercury pressure, N : N-dimethylacetamide containing 0.013 per cent of acetic acid is obtained.

Abstract: 419,113. Regulating. DODSON, E., 66, Lewin Road, Streatham, London. Sept. 16, 1933, No. 25687. [Classes 7 (iii) and 7 (vi).] In supercharged or other high-compression aircraft engines having a boost control connected with the throttle control for automatically preventing the pilot from opening the throttle more than is safe for a given altitude, the pilot's throttle lever is also connected with means for changing the datum of the boost control in such a manner as to increase the induction-pipe pressure as the throttle lever moves towards the full-open position. In this way, the pilot is prevented from obtaining the full pressure permitted by the boost control until the throttle is at or near the full-open position. Fig. 1 shows the pilot's throttle lever a<1> connected by a link a<5>, bellcrank a<6>, and toggle links a<7> to the mixture throttle a<9>, the toggle links being also connected by a rod a<10> to the automatic boost control d. This comprises an aneroid d<3>, Fig. 3, in a casing d<1> connected at d<2> to the induction pipe, so as to control a servomotor piston d<11> connected to the rod a<10>. The alteration of the datum of the boost control may be effected by cams d<16>, d<17> acting on a cap d<14> connected to the aneroid, the cams being adjusted by linkage b, b<1>, b2 in connection with the pilot's throttle control. Instead of moving the aneroid mechanically in this way, means may be provided for controlling a leak from the casing d<1>. The pilot's throttle lever a<1> may be connected to the mixture control lever a<2> in a manner similar to that described in Specification 419,472, so that the throttle lever cannot be moved to full-open position without the mixture control lever being also moved to the rich mixture position. The throttle lever may also be connected with the ignition timing member so that the ignition is retarded for idling, advanced for cruising, and again somewhat retarded for full power. A supplementary fuel jet on the carburetter may also be linked up to the pilot's throttle lever. An automatic mixture control, such as that described in Specification 376,341, may be provided between the lever a<2> and the mixturecontrol valve c<2>. Specification 358,289 also is referred to.
