Title: Improvements in catalytic conversion processes
IPC: C08F10/00
Filed: 1957-01-07
Abstract: In a catalytic conversion process a feed material in liquid phase is converted in the presence of a solvent and a finely divided solid granular catalyst to provide an effluent containing solvent and dissolved converted product, which is passed through a fixed bed of catalytic material to deposit the granular catalyst on the fixed bed, and catalyst-free solvent containing dissolved product is recovered after its passage through the bed.  Further feed material, dissolved in <PICT:0814775/III/1> solvent, is then converted by passage through the fixed bed. Ethylene and iso-octane together with a catalyst consisting of chromium oxide on silica-alumina, are fed to a reactor 10 where the ethylene is polymerized.  The effluent is passed to a vacuum flask unit 18 where unreacted feed is removed overhead, and the dissolved polyethylene and catalyst are passed through a heater 27 and through one of a plurality of fixed bed catalytic reactors 31, 32 and 33, where the suspended catalyst is deposited on a fixed catalyst bed of chromium oxide on silica-alumina.  The polyethylene in iso-octane is withdrawn, the fixed bed is washed with iso-octane, and further ethylene and iso-octane are passed through the fixed bed to obtain more polyethylene.  The fixed bed is washed with isooctane and regenerated with heated dry air, the finest catalyst particles being removed in the gas stream. Propylene and a mixture of ethylene and propylene may also be polymerized.ALSO:<PICT:0814775/IV (a)/1> In a catalytic conversion process a feed material in liquid phase is converted in the presence of a solvent and a finely divided solid granular catalyst to provide an effluent containing solvent and dissolved converted product, which is passed through a fixed bed of catalytic material to deposit the granular catalyst on the fixed bed, and catalyst-free solvent containing dissolved product is recovered after its passage through the bed.

Title: Process for the production of anhydrides of aliphatic acids
Inventor: GUINOT HENRI MARTIN
Filed: 1948-01-09
Abstract: Anhydrides of aliphatic acids are made by a continuous process which comprises treating the corresponding aldehyde with a gas containing free oxygen in the presence of oxidizing catalysts and of a liquid which forms an azeotrope with water, characterized in that said azeotrope is evaporated at a temperature below its boiling point by causing the oxidizing gas to circulate in a closed system comprising the reaction vessel and a condensing cooler for the vapour of said azeotrope, the reaction vessel being continuously fed with aldehyde, while the reaction mixture is also continuously withdrawn and distilled to separate the acid and anhydride formed from the other constituents of the mixture which other constituents are returned to the reaction vessel. Advantageously the reaction vessel initially contains some of the p  acid corresponding to the aldehyde to be treated.  Catalyst precipitation is eliminated by the addition of a heavy liquid, insoluble in water but a solvent for the aldehyde, acid and anhydride, and which acts as a vehicle for the catalyst after distillation of the mixtures.  In an example, acetaldehyde and oxygen as air, superoxygenated air or pure oxygen are continuously supplied to a reaction tank cooled to 30-50 DEG  C., containing acetic acid, n-propylacetate, butyleneglycol diacetin and cobalt and copper acetates, excess oxidizing gas is condensed and vapours collected and inert gases, e.g. nitrogen, optionally removed from the system, the aldehyde is converted to acetic anhydride and acid, and the water is distilled off with the propyl acetate, entrained acid or anhydride being recovered therefrom, products continuously removed from the tank for isolation and excess reactants or solvents recycled.

Title: Method and device for controlling songle or multiphase a.c. breakers
Inventor: RUNGGALDIER DIETHARD
IPC: H02P27/02
Filed: 1990-02-06
Abstract: When using phase control of semiconductor valves (4) for controlling AC voltage converters, in order to regulate the power factor it is necessary to determine the phase angle between the current I and the voltage U by measuring the time difference between the points at which the current and voltage pass through zero. However, disturbances superimposed on the mains voltage cause considerable random fluctuations, particularly in the measurement of the times of the voltage zero-passages, which are transferred to the phase angle and can result in an unstable regulation characteristic. It is therefore proposed according to the invention to make use of a reference time for the voltage zero-passage when determining the time difference, which reference time is derived from the measured values for the true times of the preceding voltage zero-passages.

Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To restrain a fan noise at idle stopping time by setting the upper limit guard rotating speed according to a demand blowoff port temperature, and setting output fan rotating speed to the upper limit guard rotating speed at idle stopping time and when reference fan rotating speed is larger than the upper limit guard rotating speed. SOLUTION: Refrigerant pressure reference fan rotating speed NP is decided from present refrigerant pressure PA/ C by using a map (S101), and for example, whether or not it is idle stopping is judged from a signal of a shift position sensor and a signal from an engine rotation sensor (S102 and S103). In case of idle stopping, the upper limit guard rotating speed NG is decided from a demand blowoff port temperature by using a map (S104). Next, whether or not it is larger than the refrigerant pressure refernce fan rotating speed NP is judged (S105), and when it is large, fan rotating speed Nf to be outputted is set as the upper limit guard rotating speed NG (S106), and is outputted to an engine computer (S108), and the fan rotating speed Nf is corrected by a water temperature, and is set as fan rotating speed Nf', and the fan rotating speed is controlled in Nf'.
