Abstract: 1340633 Production of polymethylbenzenes LABOFINA SA 7 Jan 1972 [13 July 1971 (3)] 817/72 Heading C5E Polymethylbenzenes are produced from alkyl aromatic hydrocarbons having the formula wherein R<SP>1</SP> is a C 2-6  alkyl radical, R<SP>2</SP> is a C 1-3  alkyl radical and R<SP>3</SP> is a methyl radical, n is 0, 1, 2 or 3 and m is 0 or 1 by (a) hydrogenating the alkylaromatic hydrocarbon to the corresponding alkylcyclohexane, (b) isomerizing the alkylcyclohexane in the presence of a Friedel-Crafts catalyst to provide polymethylcyclohexanes, and (c) subjecting the polymethylcyclohexanes to a combined dehydrogenation-isomerization step to produce polymethylbenzenes. The hydrogenation (a) can be carried out at 150-350 C. and 20-70 kg/cm<SP>2</SP> with a recycle ratio between 1 and 50 using a catalyst comprising 5-60 wt. per cent of Ni, or 0À1-1À5 wt. per cent of Pt, Pd, Ru, Os, Rh or an alloy of Pt with Re, on a support such as silica, silica-alumina, alumina or zeolite. The isomerization (b) can be carried out below 150 C. using 1-60 wt. per cent (based on the feed) of AlCl 3 , BF 3 , SnCl 4 , SbCl 3 , ZnCl 2 , GaCl 3 , AlBr 3 , FeCl 3 , BaBr 3  or a mixture of AlCl 3  and SbCl 3 . A promoter such as HCl, alkyl halide or olefin can be used. The dehydrogenation-isomerization (c) can be carried out at 200- 600 C. and up to 50 kg/cm<SP>2</SP> using a catalyst comprising 0À1-5 wt. per cent of a Pt group metal, or of an alloy of Pt with Re on a carrier such as, silica, alumina, silica-alumina or zeolite; the polyalkylcyclohexane feed can be diluted with aromatic compounds, e.g. alkylbenzenes. A diethylbenzene feed 10 is mixed with a recycle stream 16 and a hydrogen stream 13 and hydrogenated at 12; the diethylcyclohexane product 14 is in part recycled and in part sent together with a stream 19 of anhydrous HCl, to an isomerization zone 18 containing AlCl 3  at 30 C. The isomerized product 20 is stripped at 21 and then distilled at 24 to provide a distillate 26 boiling from 150-165 C. and a bottoms 25 which is recycled. The distillate 26 is passed to the dehydrogenation-isomerization 27 and the product 29 is passed to a fractionation column 30 from which material boiling below 192 C. is recycled and the bottom fraction passed to a crystallization zone 33 from which a durene product is crystallized and the mother liquor recycled to the zone 27.

Title: Pulse communication repeater system
IPC: H04B7/17
Filed: 1946-01-10
Abstract: 608,778. Radio signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 10, 1946, No. 958. Convention date, April 7, 1944. [Class 40 (v)] A repeater station for a pulse-modulated radio communication system includes a continuously operative receiver, means for deriving D.C. pulses from the received pulses, a generator of short D.C. pulses synchronised by the derived pulses and arranged to be irresponsive to pulses received in the intervals between the signal pulses and a radio-frequency oscillator fed with the generated pulses to produce R.F. pulses corresponding in spacing to the received pulses. The R.F. pulses received on the aerial 10 are reduced to an intermediate frequency in mixer 12, and converted to D.C. pulses in a rectifier 15. The derived pulses are fed to a local monitor circuit, and through a switch S to a pulse generator comprising a valve 21, the anode and control grid of which are connected to separate windings of a pulse transformer 20. An artificial line L, one end of which is connected between the cathode, maintained at a positive potential, and earth, has a constant current valve 22 connected across it. The operation of the pulse generator is described in Specification 594,659. When the system is acting as a repeater, the grid bias and cathode resistances of modulator valve 22 are such that the natural period of the pulse generator is longer than the greatest interval between two consecutive received pulses, but the voltage across line L is dissipated sufficiently rapidly to enable the derived pulses applied through switch S to trigger the pulse generator. The pulse generator may be disconnected from the rectifier 15 by opening switch S, and repetition frequency modulated pulses produced by closing switch S1, thus increasing the current flowing through valve 22, the conductivity of which is varied by modulating signals applied to the control grid. The output of the pulse generator 21 is taken from transformer 20 to control a magnetron oscillator 24, which feeds an aerial 25.

Title: A process for removal of mercury vapor and/or vapor of noxious organic compounds and/or nitrogen oxides from flue gas from an incinerator plant
Inventor: MOLLER JENS THOUSIG
IPC: B01D53/34
Filed: 1991-07-18
Abstract: The ability of activated carbon to remove mercury and noxious polyorganic matter, especially chlorodibenzodioxins and -furans from incinerator flue gases is utilized in an efficient manner by suspending powdery activated carbon in the flue gas in connection with a conventionel spray absorption process in which the acidic componente of the flue gas are neutralized by means of basic absorbents. The cooling of the flue gases in the spray absorption process provides an efficient adsorption onto the powdery activated carbon and the separation of said powdery activated carbon from the flue gas is substantally facilitated by the presence of the particulate material formed by the spray absorption process. Also an improved removal of nitrogen oxides is obtained.

Abstract: PURPOSE: To unnecessitate a special heating equipment and fuel and to start the operation of the titled heat exchanger for the exhaust gas of sintering while preventing the system from being damaged, by a method wherein a primary heating for internal parts is conducted by using unnitrified exhaust gas and then the internal parts are heated to a predetermined temperature by denitrified exhaust gas, at the time of restarting the operation of the heat exchanger after cleaning the interior thereof.  
     CONSTITUTION: After cleaning the interior of the heat exchanger, heat-transmitting elements of the heat exchanger are rotated, an inlet valve 5 for unnitrified exhaust gas is opened and the exhaust gas at about 100°C is introduced so as to heat the internal parts to about 100°C. Then, an outlet valve 6 is opened and an inlet valve 7 for denitrified exhaust gas is opened so as to heat the internal parts to about 200°C by the exhaust gas which is at about 380°C, and an outlet valve 8 is opened to allow the denitrified exhaust gas to flow. Accordingly, since the internal parts are prevented from being contacted abruptly with the denitrified exhaust gas which is at a high temperature, the special heating equipment and fuel are unnecessitated, economization is enhanced and the system can be prevented from being damaged.

Title: Positive resist pattern forming method
Inventor: SUGANUMA MIYUKI
IPC: G03F7/40
Filed: 1990-01-05
Abstract: PURPOSE:To prevent the occurrence of explosion even when ions of a high dosage are implanted by a method wherein a developed resist layer is heated up, light of photosensitive wavelength of resist is projected thereon while the temperature is being raised, and the low atomic decomposition product containing nitrogen and the like in the resist layer is released to outside the resist layer. CONSTITUTION:A substrate of silicon and the like is coated with a positive resist layer 2, and when it is developed by exposing to ultraviolet rays, the exposed part is removed and a positive resist pattern 2a is formed. Then, the developed positive pattern 2a is cured, and a positive resist pattern 2b is formed. In this curing process, temperature is slowly raised from the heat-resistance temperature or lower to the heat-resistance temperature or higher, and when strong ultraviolet rays 4, having a wide wavelength range, are projected, nitrogen 5 in the positive resist layer 2 is released to the outside air effectively and, at the same time, the positive resist layer 2 is cured. An impurity-added dose region 7 is formed by conducting a high-dosage ion implantation 6 using the nitrogen-released positive resist pattern 2b as a mask. No deformation by explosion occurs on the nitrogen-released positive resist pattern 2b even when a high dosage ions are implanted.
