Patent EP-0411112-A1 (EP)
Title: Heat exchanger.
Inventor: WALLSTEIN DIETER
IPC: F28F19/00
Filed: 1990-02-19
Abstract: A heat exchanger for cooling hot raw gas with aggressive constituents and for heating the pure gas obtained by purification of the raw gas comprises a housing with two side walls and an upper and a lower tubesheet. The inner side walls are associated with partitions to form flow channels. The ends of a plurality of exchanger tubes parallel to each other and to the side walls are inserted in the upper and lower tubesheets. The hot raw gas flows through the exchanger tubes and the pure gas flows through the housing perpendicular to the exchanger tubes. The housing and the partitions are made preferably of highly corrosion-resistant sheet metal and the exchanger tubes are made preferably of glass. To improve this type of heat exchanger so as to obtain the desired heating of the side walls and hence prevent corrosive condensation, with a relatively simple structure, the pure gas outlet from the heat exchanger communicates through at least one pure gas duct (4) with the flow channels (4) of the two side walls (3). The pure gas ducts (4) open into the upper and/or lower regions of the flow channels (14). The flow channels (14) have front outlet orifices (10) for the recycled pure gas.

Abstract: Appareil pour former et rendre compactes des serviettes hygiéniques (C, C', C'') servant à absorber des fuides organiques. Ces serviettes consistent en plusieurs couches partielles (C-1, C-2, C-3) et sont, le cas échéant, traitées avec un agent superabsorbant. Pour former au moins une couche de serviettes hygiéniques (C-1, C-2, C-3), une bande rotative (A1) est dotée, sur toute sa longueur, de moules d'insertion espacés en forme d'auge (20-1, 20-2, 20-3) où peuvent s'insérer des garnitures de mise en forme (22). Des dispositifs de production (11, 12-1, 13, 30; 11, 12-2, 13, 30; 14, 15; 16, 17, 30; 11, 12-3, 13, 30; 18, 18'; 27, 28, 28', 31; 19, 19', 19'') sont disposés par deux le long de la bande rotative (A1), sur la trajectoire linéaire d'aller et de retour. Une bande d'entraînement (A2) va en sens contraire de la bande rotative (A1) et peut être comprimée contre cette dernière. Un dispositif de compactage thermique (40) est suivi, dans le sens du transport, de rouleaux de calandre et/ou de gaufrage (50, 50') et consiste en un cylindre de chauffage (41) doté d'une bande de compression (A3).

Abstract: Cette chemise à perforations pour classement convient notamment comme pochette de présentation. Elle est composée d'un élément de base, par exemple en carton, ou de deux éléments de base (10, 12) réunis par un pli (14), et présente des éléments d'enveloppe (16-22) délimités sur plusieurs côtés par des plis. Un de ces éléments au moins est un rabat (16-22), adjacent à un petit côté de l'élément de base (10, 12) et comportant au moins une patte de fermeture perforée (26), séparée du et parallèle au petit côté. Lorsque le rabat (16-22) est rabattu, cette patte s'insère à travers une fente (24) s'étendant le long d'un côté long de l'élément de base (10, 12). On obtient ainsi une chemise où les feuilles sont bien maintenues de tous les côtés, qui ne requiert que peu de matériau et qui est peu coûteuse à fabriquer. Les autres avantages sont les possibilités d'emploi multiples et la souplesse de la fermeture.

Abstract: Un dispositif pour introduire des troncs d'arbres comporte une structure de corps (1) et des éléments de support (2) agencés sur cette dernière ainsi que des éléments de support (3) pour introduire un tronc d'arbre situé entre les organes d'introduction. Les éléments de support avec les organes d'introduction associés se rapprochent et s'éloignent au moyen d'organes motorisés (4), en vue d'ajuster à la texture du tronc l'écartement entre les organes d'introduction situés de chaque côté de ce dernier. Le dispositif comprend des éléments (5) qui, par aboutement contre le tronc, positionnent ce dernier de sorte que les axes médians longitudinaux du tronc vont prendre différentes positions en général transversalement par rapport au sens (R) de la mobilité relative des organes d'introduction en direction et à l'opposé l'un de l'autre en fonction de la texture du tronc. Le dispositif comprend également des moyens (24, 25) pour déplacer les organes d'introduction (3) supportés par les éléments de support (2) par rapport à la structure de corps (1) afin de maintenir les organes d'introduction (3) dans une position en général opposée au tronc, indépendamment des variations de situation de l'axe médian longitudinal du tronc par suite des variations de texture.

Abstract: A method for adjusting the thickness of a course consisting of road-building material to be laid down by a finisher on a foundation by raising a laying-down board of the finisher to a height adapted to the desired thickness, and a finisher suitable therefor are described, the laying-down board of which finisher is connected to the finisher via an articulation point for floating support on the course, the articulation point being height-adjustable via a first lifting cylinder, and the laying-down board being connected to a second lifting cylinder which is unlocked during laying down. In order to simplify the adjustment of the thickness of the course to be laid down, it is proposed to place the laying-down board flat on the foundation for initial adjustment of the course thickness, to determine this position by measurement transducers and subsequently to raise the laying-down board by the first and second controllably height-adjustable lifting cylinders to a height corresponding to the desired laying-down thickness plus rolling quantity. <IMAGE>

Abstract: In the method for manufacturing activated carbon from cellulosic material, the material is treated with a phosphoric compound like an ammonium phosphate compound which forms an ester with cellulose. The material is pyrolysed and activated in a suitable atmosphere and using a suitable temperature-time program. Activation is performed in a carbon dioxide atmosphere by a reduction reaction of carbon dioxide as the carbon dioxide gas flows past the material under treatment. As the cellulosic material, regenerated cellulose fibre like viscose fibre is used. Activation stage is continued at over 850  DEG C until yield of about 14-25 % is obtained whereby BET values of 1000-1600 m<2>/g are reached.

A two-layer film formed of said resin laminate and spread over a glass vessel such as a glass bottle or over a glass window pane can prevent the glass from scattering when broken into fragments. Even when a glass bottle is washed with alkaline solution, said film neither exfoliates from the glass nor degrades with swelling, thereby affording much advantage in practical use.
