Patent CZ-344195-A3 (CZ)
Title: Process for producing substantially hollow cylindrical casting and the hollow cylindrical casting
Inventor: AUS DER AU HANS RUDOLF
IPC: B29L22/00
Filed: 1994-06-13
Abstract: For the manufacture of substantially hollow-cylindrical castings (5), especially leading-in insulators for conductors under high voltage, a more or less liquid casting material (50) is introduced into a substantially hollow-cylindrical casting mould (2) that is driven in rotation. Before the introduction of the casting material, the casting mould is heated to a temperature above the gelling temperature of the casting material. The casting mould (2) filled with casting material (50) is driven in rotation until a casting (5) that is substantially set solid has been formed. The casting so formed is then removed from the casting mould. Before the introduction of the casting material into the casting mould, however, a substantially hollow-cylindrical mesh fabric (1) is introduced into the heated casting mould (2) concentrically to the axis of rotation (22) thereof, and only then is the casting material (50) introduced into the casting mould (2).

Title: Method of producing cellulose fibres
Inventor: FRISCHMANN GUNTER
IPC: D01F2/00
Filed: 1996-03-19
Abstract: The invention concerns a method of producing cellulose fibres by extruding a spinning solution containing dissolved cellulose in a gaseous medium over a predetermined gas section, subsequent immersion in and passage through a coagulation bath over a predetermined coagulation section, and stretching and winding up the resultant cellulose fibres. The invention is characterized in that, after the gas section, the extruded spinning solution (2) is introduced into a coagulation bath which is accelerated to a predetermined speed and flows steadily at least approximately in the direction of the extruded spinning solution. The coagulation liquid (7) is fed laterally into the path of the spinning solution and the directions of flow of the spinning solution and of the coagulation liquid are maintained at least approximately parallel (3) over the entire coagulation section. On leaving the coagulation section, the resultant cellulose fibres (5) are laterally deflected (4) and then wound up (6).

Title: Procede, appareil et support d'acquisition d'entree de symboles en reponse a plusieurs mouvements d'actionneurs
Inventor: BEBLOW JASON MICHEAL
IPC: G06F3/023
Filed: 2001-11-06
Abstract: La présente invention permet d'introduire facilement et efficacement des informations au moyen d'un procédé, d'un appareil, d'un clavier d'un appareil de communications de façon à recevoir une entrée utilisateur en associant différents déplacements d'un actionneur à des symboles de différents ensembles de symboles. Le déplacement d'un actionneur dans un sens généralement parallèle à une surface de référence peut être associé à un premier ensemble de symboles, tandis que le déplacement de l'actionneur généralement perpendiculaire à la surface de référence peut être associé à un second ensemble de symboles. Le déplacement de l'actionneur dans le premier sens permet d'appeler des caractères non numériques tels que des lettres de l'alphabet, et le déplacement de l'actionneur dans le second sens permet d'appeler uniquement des caractères numériques. Le second sens peut être un sens similaire à celui d'un bouton-poussoir traditionnel d'un clavier de téléphone généralement utilisé pour appeler des numéros, par exemple. Une simple touche peut donc être utilisée comme un bouton-poussoir traditionnel pour appeler des caractères numériques et la même touche peut être déplacée dans un sens généralement parallèle à la surface pour appeler des caractères non numériques, par exemple. L'utilisateur peut ainsi associer des sens de déplacement à des ensembles de symboles séparés, ce qui simplifie l'introduction des données.

Abstract: According to an aspect of the present invention one or more radio units of a wireless device are used to measure or detect clues about the radio propagation environment and type of space that surrounds a wireless device. From the measurements, the wireless device may determine the type of location that it is located within, whether that is simply a determination between inside and outside or a more complex determination of the type of building or space that the wireless device is located within. In either case, this determination can be used to automatically change/adjust the radio system operation parameters the wireless device operates in accordance with. With the type of location determined, a wireless device may then automatically select the appropriate radio system operation parameters for the type of location that it is in and the corresponding regulations that apply.
