Granted: 1991-11-13
Abstract: The method is used for the production of a web of interconnected bags from a half-tube web consisting of a material which is capable of being adhesively bonded and/or sealed. In the region of the first of the two longitudinal outer edges running in the direction of feeding of the half-tube web, firstly at least one continuous strip is fitted in each case on the top side and on the underside of the half-tube web in pockets which are continuously integrally formed on the web during its feeding, before the separation of the bags, and the two parts of the half-tube web lie loosely one on top of the other in the region of the second longitudinal outer edge which is parallel to the first. Then, the strips are cut to length and their ends are interconnected and the half-tube web is sealed in a cyclical manner transversely, preferably perpendicularly with respect to the feeding direction to form in each case one bag, which is transported transversely, preferably at right angles to the feeding direction and all of these bags are interconnected. In this arrangement, either the pocket of the top side or that of the underside of the half-tube web protrudes beyond the respective other pocket, transversely with respect to the feeding direction, to form the first longitudinal outer edge. Every bag, which is sealed transversely with respect to the feeding direction and is transported in a direction which likewise runs transversely with respect to said feeding direction, is transported by one bag length. Then, the half-tube web is further transported by a bag width and with its first longitudinal outer edge overlaps, in an overlapping region, the second longitudinal outer edge of the bag which is transported transversely with respect to the feeding direction. Finally, the overlapping region is sealed by means of a sealed seam to connect two bags lying one behind the other in the longitudinal direction of the bags.

Granted: 1992-01-02
Abstract: The inefficiency of the nitrogen stripping section of a high purity oxygen-producing air distillation plant is reduced. This allows increased recovery of byproduct argon and in some cases increased recovery of refrigeration work also. The improvement is obtained by evaporating kettle liquid with condensing argon rectifier vapor in two sequential stages, to yield vapor streams respectively having more and less O2 content than the kettle liquid, and separately feeding them to the N2 removal column. The improvement is applicable to both dual and triple pressure processes. Referring to FIG. 1, kettle liquid is supplied via valve 11 to the top of contactor 18, and overhead reflux condenser 13 of argon rectifier 14 reboils the bottom of contactor 18. Vapor streams of differing O2 composition are withdrawn from above and below 18.

Abstract: In customary processes for the continuous manufacture of a length of fibrous insulating material, made in particular of mineral fibres, a primary web which comes from a collecting chamber and has been impregnated with binders and impregnants is compacted and passed into an oven for curing the binders and impregnants. 
<??>To devise a process which with a minimum of complication makes possible a systematic arrangement of fibres having particular surface properties or of properties of the fibrous insulating material within said material, it is proposed that upstream of the curing oven the primary web be divided into two or more subsidiary webs, one subsidiary be lifted off, strongly compressed with alignment of fibres and then be brought back together with the other subsidiary web(s) and all the webs together then be cured in the curing oven.

Title: Systeme de centrifugation continue et procede de derivation directe d'un materiau de densite intermediaire a partir d'une suspension

Filed: 1988-01-12
Granted: 1995-03-08
Abstract: Un système de séparation continue de matière de densité intermédiaire et plus légère, telle que du plasma riche en plaquettes sanguines à partir de sang entier envoie du sang au travers d'un intervalle de centrifugation divergent (65) entre des parois interne et externe d'un rotor (42) tournant autour d'un axe central à l'intérieur d'une enceinte. L'action de centrifugation crée un écoulement stratifié le long d'une section intermédiaire. Cependant, en créant des sillons de fuite dans l'intervalle entre le rotor (42) et l'enceinte (11), des configurations de remélange localisé tendant à se déplacer dans la direction opposée sont induites dans la matière stratifiée. Du plasma riche en plaquettes peut ensuite être extrait au travers d'orifices adjacents (58) de concentré de plaquettes, lesquels orifices sont ménagés sur la paroi intérieure du rotor (42). Un système à passage intérieur fait passer le plasma riche en plaquettes vers un réservoir (23) de concentré de plaquettes. La recirculation du sang dans l'intervalle rotor-enceinte entre la sortie et l'entrée, et l'action de pompage effectuée par l'intervalle de centrifugation divergente (65) contribuent à améliorer les niveaux de débit et de concentration. Une section initiale à intervalle étroit est placée avant l'intervalle de centrifugation (65) de manière à limiter la propagation vers l'arrière de configurations circulatoires induites.

Title: Method to protect a centrifugal compressor against surge by venting via a vent valve and system to realize the method
IPC: F04D27/02
Filed: 1989-02-22
Granted: 1992-08-26
Abstract: In the case of known methods of the type stated a continuous surge limit control and a safety control, intervening in an emergency, are operated in parallel. When the safety control responds, this results either in complete opening of the venting valve which cannot be maintained, resulting in a fall in pressure in the downstream process, or the rate of opening of the venting valve is limited by the actuating device of the venting valve, which leads to slower reaction in the case of a malfunction. The new method is intended to rectify this drawback. 
<??>The new method is characterised in that, when the safety control responds, the pressure medium for actuating the venting valve is led off directly, avoiding the position regulator, and that when the safety control returns leading-off of the pressure medium ceases and the control is again taken over solely by the surge limit controller and the downstream position regulator. The new method means that, in the event of rapid opening, the venting valve is adjusted at its technically maximum possible rate of adjustment, independent of the position regulator, and only as far as necessary in the opening direction in order to catch any disturbance occurring. Delayed or excessive or prolonged venting with its detrimental consequences is thereby avoided. 
<??>The new method is suitable for turbocompressors in various spheres of application, in particular for large compressors.

Abstract: Lofted non-woven materials are formed by bonding fibres and used for, e.g. furniture filing and heat insulation. The flammability of these materials is an important characteristic. The use of copolymer emulsions having defined Tg, molecular weight and solution viscosity as binders allows the material to melt away from an open flame. Thus the flammability of the non-woven material is reduced.

Title: Slide profile for realisation of profiles with a floating latch

Abstract: The lower profile element is substantially of a U-shaped section and includes wings having each a median zone with a semi-cylindrical channel prolongated by a bent-over portion provided for covering V-bent vertical ends of side branches of the upper profile element. A wing of the lower profile element is cut out in order to form a row of teeth having each a trapezoidal shape prolongated by a rectangular shape in order to cooperate with an L-section latch-comb formed with rectangular openings and freely mounted on a pin which is displacable by a control of the slide. A spring applies to the latch-comb a pressure permitting a passage of teeth of the latch-comb through openings formed in the upper profile element so as to cause a penetration of the latch-comb into the openings between the row of teeth of the lower profile element for latching the upper profile element on the lower profile element.
