Abstract: Para-xylene is separated from a feed mixture of C8 isomers of xylene and C9 aromatics by contacting the para-xylene-containing feed mixture with a crystalline aluminosilicate zeolite, e.g. an X or Y zeolite adsorbent having Group IA or IIA cations, e.g. barium and/or potassium, at exchangeable cationic sites. The para-xylene is selectively adsorbed onto the adsorbent. The non-adsorbed feed is then removed from the adsorbent and the para-xylene recovered from the resulting rich adsorbent by desorption with a desorbent comprising 1,2,3,4-tetrahydronaphthalene or an alkyl or dialkyl derivative of 1,2,3,4-tetrahydronaphthalene or mixtures thereof. The majority of the C9 aromatics and the xylene isomers are typically recovered in the raffinate and can be separated from the desorbent by fractionation of the raffinate and the recovered desorbent recycled to the process.

Abstract: In the continuous kraft pulping of comminuted cellulosic fibrous material (e.g. wood chips) to produce paper pulp, viscosity for a given Kappa Number is significantly increased (e.g. at least about 20%) by adding kraft white liquor to the wash recirculation loop (38-40) in a continuous digester (19). Optimum results are obtained when kraft white liquor is also added to a recirculation loop (28-30) at a central portion of the digester, so that the majority of the digester has countercurrent flow between white liquor and cellulosic material. About 5-20% of the total white liquor necessary to effect kraft cooking is introduced in the wash circulation, and about 10-20% is introduced into the central portion recirculation. The temperature in the wash zone is maintained at about 140-175 DEG C. <IMAGE>

Title: Flow measuring apparatus
Inventor: SCHWIDERSKI HANS W
IPC: G01F1/60
Filed: 1991-04-08
Granted: 2000-11-14
Abstract: A liquid flow measuring system which, by means of a suitable timing sequence, is able to detect unbalanced voltage generation which occurs when the tube element through which the liquid is flowing is not completely full and, by means of a correction process, supplies an output signal which is proportional to the rate of flow. When the tube element is full, the system operates in the same way as a normal magnetically inductive flowmeter. If the level in the tube element falls, electrodes which are installed in the lower half of the tube element and other electrodes, if necessary, can be used exclusively or additionally to record the measured values. Moreover, with a view to improving the recording of measured values when the level falls below a specific limit, an arrangement of electromagnets, specially optimized for partially filled tube elements, can be activated instead of the normal arrangement of electromagnets.

Filed: 1991-08-28
Granted: 2001-09-18
Abstract: A method (and apparatus) is disclosed for the spectroscopic determination of the amount ~Nn of one constituent N of a fluid mixture 0 in another constituent n of the mixture, following separation of the mixture into its constituents 1,...,M (where n, N ~ M). The method involves determining the absorptivities a n (n = 1,...,N) of the M constituents from spectroscopic measurements and computing the amount ~Nn from a mathematical expression containing the absorptivities a n and a N which are expressed or expressable as the quotient a n/a N only. The method is insensitive to changes in the absorptivities due to feed variability or changes in upstream process conditions. A modification to the method involves determining the content ~N0 of constituent N in feed 0 from a mathematical expression containing a0, where a0 is the absorptivity of the feed 0, and a N, which absorptivities a0 and a N are expressed or expressable as the quotient a0/a N only.

Title: Plug element for electric connection, in particular distribution boards or the like
Inventor: BOROS FERENC
IPC: H01R25/14
Filed: 1991-04-17
Granted: 2000-11-07
Abstract: The contact properties of plug elements deteriorate even with slight twists.  By using elastic intermediate, current-transmitting elements, a relative insensitivity to twists is obtained.  In order to reliably secure the intermediate elements to bearing or current-carrying-off elements, however high costs are incurred. In order to eliminate the disadvantages of the state of the art and to obtain good contact properties with a reliable fastening, the contact bars are imbedded in a plug shell in such a way that they are located in window-like openings and engage slots by their edges. The current is led by contact tabs that protrude from the plug shell. The plug shell in composed of two identical halves which may be interconnected by interlocking and by adherence without any additional fastening elements. With these plug elements, a reliable contact of busbars is easily obtained and it becomes possible to supply with load current plug-in racks of distribution boards with plug-in racks and reduced plugging forces.     Besides other advantages, this plug element is rugged and easy to mount.
