Abstract: L'invention concerne un tissu ignifuge composé de fibres mélangées, comprenant une grande proportion de matière inflammable et une petite proportion de matière ininflammable et ignifuge. Ladite matière coupe-feu ou ignifuge se présente sous la forme de fibres réparties de manière uniforme dans le tissu, et suffisamment fines pour réduire la proportion en poids des fibres par rapport au poids des fibres de la matière inflammable, à une valeur inférieure à 25 %, lesdites fibres de la matière coupe-feu ayant toutefois une résistance suffisante pour former une matrice, à laquelle ladite matière inflammable peut coller sous la forme d'un charbon de bois ininflammable après combustion, de sorte que l'on peut former une couche de charbon de bois indépendante, coupe-feu et ininflammable à partir du tissu, après avoir exposé ce dernier au feu.

Title: A valve
Inventor: RASMUSSEN HELGE KJAER
IPC: F16K5/06
Filed: 1991-05-28
Abstract: A valve intended to be inserted in a pipe in order to shut-off the latter is provided with a valve member (2) being rotatable inside a valve body (1). Such valve makes it possible to fulfil three functions, viz. a shut-off function, a cleaning function and a metering function. It is possible to clean a filter (30) without demounting a phial element used for the metering function. This is obtained as the filter (30) is located inside the valve member in such a way that it is possible to remove the filter through an opening (29). The opening (29) is different from an opening (46) through which a phial pocket member (33) for the phial element is mounted. When cleaning the filter (30) the phial element is shut-off and a cap (56) is removed. Hereby the filter is free and can be removed through the opening 29. Only the amount of fluid provided in the flow passsage (15) of the valve member (2) will leak during the cleaning operation.

Abstract: A method is disclosed for the preparation of finely divided, electrically conductive tin(IV) oxide. In a first step tin(IV) oxalate and/or oxalates of polymeric tin(IV) compounds are obtained by electrolysis, in which the anode consists of tin or a tin alloy which contains a doping metal, and the cathode consists of a metal or graphite. The two electrodes are separated by a diaphragm or an organic membrane which is permeable to hydrogen ions and oxalic acid solution is used as electrolyte. Tin(IV) oxide is prepared in the second step by calcining the oxalates obtained from the solution of tin(IV) oxalate and/or oxalates of polymeric tin(IV) compounds, to which known doping agents have been added in conventional amounts.

Abstract: To deform a sheet material into a wave form, a fixed row (2) of form tools (4) is pressed against a movable row (3) of form tools (5). The form tools of the two rows are in addition simultaneously pushed together, thus reflecting the shortening of the material during the deformation. This ensures that no relative displacement between the material and the end faces (6, 6') of the form tools (4 and 5) takes place even if there are a plurality of shafts with a relatively great height. The movable row of form tools is arranged on a rotor while the fixed row is secured at a work station in the range of rotation of the rotor.

Abstract: A mobile telephony system includes an internal part-system (6), which is installed in a building (1) and an external part-system (7). The internal part-system has internal base stations (BSI) which are connected to a mobile switching centre (MSC), to which external base stations (BS1, BS2) are also connected. The mobile telephony system is assigned a frequency band which comprises a plurality of channels. The external part-system is divided into cells (C1, C2, C3) and has fixed channel assignment with a few channels to each external base stations (BS1, BS2). The internal part-system is adaptive and the internal base stations (BSI) have access to all channels of the system. In order to determine whether a mobile station (MSI) belongs to the internal or to the external part-system, an internal identification word is transmitted from the internal base stations and an external identification word is transmitted from the external base stations. When the signal strength of the internal identification word exceeds a threshold value, the moble station transmits an internal identification word to the internal base stations (BSI). If the signal strength falls beneath this treshold value, the mobile station (MSI) identifies itself to the external part-system (7).
