Title: Supported catalyst for 1-olefin(s) (co)polymerization
Inventor: CHANG MAIN
IPC: C08F4/639
Filed: 1993-04-08
Granted: 1998-01-06
Abstract: This invention relates to a supported catalyst composition useful in the polymerization of olefins and to a method for its production. The catalyst is formed by first reacting a trialkylaluminum compound with a transition metal metallocence, and subsequently reacting the resulting material with the undehydrated support material to form a solid product containing at least 20 grams of support material per milimole of transition metal. The resulting supported catalyst has a level of activity comparable to that of conventionally made supported catalysts which are achieved at active metal loadings which are reduced from the loadings used in the previously known metallocene-alumoxane catalysts by at least 20 %, and preferably 50 %. The invention particularly relates to the use of undehydrated silica gel containing from 6 to 20 per cent by weight adsorbed water as the catalyst support material.

Title: Secure communication apparatus and method
Inventor: MANDELBAUM RICHARD
IPC: H04L9/36
Filed: 1995-02-06
Granted: 2000-06-27
Abstract: A communication apparatus (e.g., a fax apparatus) (Figure 1) provides secure message transmission by sending messages having an unrestricted portion (e.g., a header) and a restricted portion (e.g., the body of the message). The unrestricted portion is always outputted at the receiving apparatus; however, access to the restricted portion is provided only in response to receiving predetermined information from a user (e.g., a message recipient). This information may include either the use of a password or the use of a PIN code following the insertion of a user's smart card into the receiving apparatus. If the restricted portion is encrypted, the user must either provide the decryption key to enable the receiving apparatus to decrypt the restricted message or his/her smart card must perform the actual decryption of the restricted message.

Title: Process for the treatment of electric arc furnace dust
Inventor: MCELROY RODERICK O
IPC: C22B7/02
Filed: 1994-02-16
Granted: 2001-05-01
Abstract: In a process for the treatment of electric arc furnace (EAF) dust, the dust is first subjected to atmospheric leaching with a ferric  chloride solution and thereafter subjected to treatment in an autoclave at an elevate d temperature and pressure for conversion of low tempera ture stable goethite (FeO.OH) to a filterable crystalline hematite (Fe2O3) in an acidic chloride solution. Zinc is recovered from the sol ution by solvent extraction using a solvating extractant followed by stripping and  zinc recovery by electrolysis of zinc chloride or zinc sulphate solution. Load is separated from the solution by cooling to precipitate lead  chloride.

Abstract: Ce réacteur (10) passif étagé interphase facilite l'interaction interphase d'une première substance en phase liquide avec une seconde substance en phase liquide non miscible, en phase solide, ou en phase gazeuse. Le réacteur comporte plusieurs étages (C, D et E) qui définissent un passage d'écoulement pour les substances en différentes phases. Chaque étage définit par sa forme un passage d'écoulement (12) sensiblement incurvé et dont le centre de courbure est situé sur un côté du passage d'écoulement (12). Ainsi par exemple, les étages D et E ont leurs centres de courbure respectifs (14 et 16) du côté opposé au passage d'écoulement (12), et en fonctionnement, lorsque les substantces passent au travers du réacteur (10), les particules de la seconde substance subissent une migration forcée au travers de la première substance, d'abord dans un sens, puis sensiblement en sens inverse, en raison d'un champ inertiel provoqué par le changement de direction ainsi généré. Les différences de densités relatives des phases respectives créent des différences dans les forces inertielles qui s'appliquent à chacune des phases du mélange dans le sens général de circulation du passage d'écoulement (12). L'interaction entre phases qui en résulte se caractérise par une interaction mécanique imputable en l'occurrence aux collisions et au transfert d'énergie, et par des réactions chimiques imputables en l'occurrence à une oxydation et des échanges d'ions. Le réacteur (10), qui ne comporte aucune pièce mobile, est de construction relativement simple, et a une efficacité élevée car il permet d'obtenir des cinétiques de réaction élevées, des taux élevés de transfert de matière et des débits de brassage élevés.

Abstract: A protective door jamb system integrally connected to a door frame. The door jamb system of the present invention includes both a door stop and jamb cladding each manufactured from an extruded plastic product such as hollow rigid plastic, cellular plastic, granular filled plastic or fiber filled plastic. The door stop and jamb clad are each designed to attach to a door jamb substrate through compression deflected fingers. The door jamb system of the present invention may also include a weather strip to ensure a weather-tight seal of a door when the door is closed into the frame. The jamb clad of the present invention covers the recessed portion of the door jamb substrate adjacent the jamb to completely cover the substrate and thereby increase both the structural and aesthetic integrity of the frame. The door jamb system of the present invention therefore permits use of otherwise aesthetically unpleasing, and less expensive material, for the door jamb substrate, with the advantage being that a high quality product may be manufactured for less associated cost.
