Title: Process for purifying an oxidation waste gas with recovery of energy
Inventor: MODIC RUDOLF
IPC: F02C3/22
Filed: 1991-08-20
Abstract: Abstract The invention relates to a process for the purification of an off gas which originates from a reaction process operated under pressure and in particular from an oxidation process operated using oxygen-containing  gas  and which  is  contaminated with aliphatic and/or aromatic substances,  with at least partial recovery of  the energy contained in the off gas,  in which process the off gas stream is expanded in an expansion turbine for generating mechanical or electrical energy. The off gas to be purified originates in particular from the oxidation of para-xylene (p-X) with air by the so-called Witten DMT process for the preparation of dimethyl terephthalate (DMT).     The  invention  envisages  that  the  off  gas  is  burned  under pressure and the resulting flue gases are used for generating mechanical or electrical energy in an expansion turbine. The invention preferably comprises the following main steps:   a)   Partial condensation of the substances to be washed out, at about 35-60°C; b)   Absorption  with  methyl  para-toluate  (p-TE)  or  with  a mixture of p-TE and methyl benzoate (BME); c)   Absorption with BME and/or methanol; d)   Absorption with water; e)   Combustion under pressure, if necessary with the supply of oxygen and combustible products.

Title: Reversible transformation of hydrocarbons
Inventor: KALOCSAI GUY IMRE ZOLTAN
IPC: E21B35/00
Filed: 1991-10-29
Abstract: 2094044 9207917 PCTABS00013 The invention is directed to a method for reversibly transforming a hydrocarbon into a phase more suitable for subsequent handling but from which the original hydrocarbon can be readily recovered. The hydrocarbon is contacted with a first reagent - which is usually a fatty acid - and then added to a second reagent - which is usually a mixture of Latex and an acetate - to produce an absorbent which absorbs the hydrocarbon to form a homogenous product.  The elasticity of this homogenous product can be controlled. This homogenous product can be readily handled, collected and moved and the original hydrocarbon can be recovered by simple evaporation, distillation or re-dissolution of the homogenous product. The invention is of particular use in the recovery of hydrocarbons from an oil spill on water, for the sealing of leaking or damaged containers of liquid hydrocarbons, for the preparation of solid fuels and for the quelling of oil-well fires.

IPC: H04N1/047
Filed: 1993-07-12
Abstract: An image acquisition system includes a transport mechanism for transporting sheets of objects past a sensor. The sensor scans the objects and generates data streams which are scaled by a multiplier to compensate for the speed variation of the transport mechanism. At speeds much lower than a nominal speed, the scanning rate of the sensor is increased to generate several data streams for each scanned line, which are then combined in a single speed corrected signal stream for further processing.

Title: Capacitively coupled rf fluorescent lamp with rf magnetic enhancement
Inventor: GODYAK VALERY A
IPC: H05B41/28
Filed: 1993-10-14
Abstract: A fluorescent light source includes a fluorescent lamp having first and second electrodes at or near the ends thereof for capacitive coupling of RF electrical energy to a low pressure discharge within the fluorescent lamp and an RF source having a first output lead electrically coupled to the first electrode and a second output lead electrically coupled to the second electrode. The electrodes include circuitry for inducing an RF magnetic field within the fluorescent lamp in the region of the electrodes. The RF magnetic field improves the performance of the capacitively coupled RF light source by creating an auxiliary inductive RF discharge near the capacitive coupling electrodes. The inductive discharge locally increases the plasma density and the electrode sheath capacitance and provides a reduction in RF voltage across the capacitively coupled fluorescent lamp.
