Title: Air cooler for aircraft fuel and lubricant - uses auxiliary gas turbine to provide cooling air supply before takeoff
IPC: B64D37/34
Filed: 1970-11-24
Abstract: The air system is for aircraft fuel/lubricant, and uses the auxiliary gas turbine (5) to ensure the same airflow through the heat exchanger (8) before takeoff as provided by wind when in flight. Ducting containing a remotely-operated shutter (16, 17, 18) and a deflector plate (12) allows air to be drawn through the fuel/lubricant heat exchanger, either by the forward motion of the aircraft (ducts (11, 7, 19)), or by the auxiliary gas turbine (ducts (11, 7, 6)). The inlet (4) leads into a plenum chamber (13). Toe ensure the gas turbine air supply is adequate under all ambient conditions, the chamber has a supplementary direct inlet (20). In flight, a shutter (15) coupled with the one controlling the cooling air flow is opened so that the auxiliary turbine receives its full air supply at the same time as the cooling air flow is diverted.

Abstract: PURPOSE:To make feeding of a toner to an aperture smooth and to make recording characteristics such as resolution good by using a recording electrode the surface of which facing to the charged particle feeding side in the neighborhood of the aperture is made rough and performing recording by direct controlling. CONSTITUTION:A toner is rotatably moved by being pinched between a base material 31 of an aperture electrode and a carrying roller 23. In this case, as the surface of the base material 31 is formed into a rough face and in addition, the surface roughness is smaller than the particle diameter of the toner, the toner 27 is well bited on the surface and the behavior is extremely smoothed. As the result, the amt. and characteristics of the toner fed to the aperture is homogenized. In a recording electrode 30, a signal from a data circuit is transmitted to a driving circuit through a conductive part and in practical, 0 volt and 60 volt are selectively applied on an aperture electrode 33. In this instance, an electric field is generated between the earthed carrying roller 23 and the aperture electrode 33 and the toner 27 pinched between the recording electrode 30 and the carrying roller 23 is energized by an electrostatic force and control of recording can be performed.

IPC: C07C253/26

Granted: 1998-04-02
Abstract: An alkane, e.g. propane, is converted to an alkene in a catalytic dehydrogenator. The resulting stream is introduced into an ammoxidation or oxidation reactor. The product formed therein is recovered in a conventional quench tower. The pressure of the gaseous effluent from the quench tower is raised and it is introduced into an absorber/stripper unit employing a liquid hydrocarbon to form a recycle stream containing unreacted alkane and alkene as well as a minor amount of oxygen, typically 1% percent by volume, and a waste stream comprising the remainder of the quench tower gaseous phase. The recycle stream is introduced into a selective oxidation unit to remover the oxygen therefrom and then recycled to the dehydrogenator. Flammability of the waste stream from the absorber/stripper is minimised by appropriately selecting the operating parameters of the process, and if necessary, by the addition thereto of a gaseous flame suppressor. The gaseous flame suppressor is removed with the absorber/stripper unit waste stream which may advantageously be combusted to provide energy for the process. A PSA unit may be utilised to remove excess hydrogen from the dehydrogenator effluent. The dehydrogenator may be a multistage dehydrogenator making it possible to do without the selective oxidation unit.

Abstract: Upstream of the reactor a balance fluid is introduced, which, at 40 degrees C and atmospheric pressure, is a gas and has a density less than or equal to that of pentane under the same conditions. The paraffins have 5 or 6 atoms and more than 2 wt.% benzene, in which the load is passed through a reactor (5) containing an isomerization catalyst in the presence of hydrogen, at a total pressure greater than 10 x 10<5> Pa (10 bars) and a mean temperature of 100-200 degrees C. The balance fluid is injected immediately upstream of the first isomerization reactor, at a level in the introduction zone where the fluids are mixed, at mid- height of the catalyst bed (6), and after preheating of the reaction mixture and before injecting the mixture into the reactor. The balance fluid contains a substantial quantity of hydrogen and/or hydrocarbons with 1-5 (or 1-4) C. The fluid also contains a small quantity of hydrocarbons with 6 or 7 C and/or inert gases such as nitrogen or other appropriate light fluid. The fluid contains a substantial quantity of the light components from a fractionating column (20) for the effluents from the isomerization unit. The composition and/or flow rate of the balance fluid is optimized as a function of the characteristics of the load to be treated, in particular its benzene content. The balance fluid is injected at a rate of 5-150 Nm<3>/m<3> of load, preferably 5-60 Nm<3>/m<3> of load, and at a temperature less than or equal to that of the reactants, preferably 20-180 degrees C. The isomerization unit contains several reactors in series (5, 8) and a section rich in non-isomerized paraffins with 5 or 6 C containing naphthenes, is separated from the effluent of the isomerization unit and is recycled immediately downstream of the first reactor. Independent claims are included for: (i) the apparatus for the above process; and (ii) the use of the unit to isomerize light petrols from catalytic cracking, on their own or part of a mixture.
