Patent EP-0303104-A1 (EP)
Inventor: MEISS LUDWIG DR MED
IPC: A61F13/02
Filed: 1988-07-27
Abstract: As is known, wound dressings are needed for burns, extensive skin wounds, skin defects or the like. Wounds of this type are susceptible to contamination by microorganisms, including fungi, and can then develop into septic wounds which are slow to heal and require a special wound dressing and wound treatment. The aim is to provide a wound dressing which is permeable to oxygen and fluids and should be biocompatible and, as far as possible, also bioactive. The proposed wound dressing comprises bodies (2) which are connected by means of connecting elements (6; 16, 18) to form a netting and which have at least on the surface a layer of ceramic or glass. In addition, the wound dressing can have a base netting, which is designed in particular as a mat, nonwoven or woven fabric and is provided with such a layer.

IPC: C08G59/52
Filed: 1988-11-02
Abstract: The invention concerns a process for producing aqueous dispersions for subsequent processing to electro-dipcoat enamels with stoving temperatures less than 160 DEG C and stoving times less than or equal to 30 minutes. These dispersions contain binders in the form of modified epoxide and amine adducts and crosslinking agents in the form of polyisocyanates blocked with amino groups. In this process, polyepoxides and compounds containing one or more, preferably two, hydroxyl groups per molecule are converted at high temperatures by catalysis to epoxide-containing intermediate products. A solvent or solvent mixture is added under external cooling and a solution is boiled under reflux, if necessary under vacuum, until the temperature is reduced to between 95 DEG C and 20 DEG C. Amines are then added to the free epoxide groups still present in the epoxy resin and a dispersion is produced after addition of the crosslinking agent by addition of a water-acid mixture or a dispersion is first produced and a crosslinking agent then added.

Abstract: An injection-control mechanism, which can be used in particular on a spacecraft, comprises a resilient element (36) such as a spring or a gas capacity, placed in between a drive element (18) and a pushing element (26). The driving energy supplied, for example, by a pyrotechnic charge (24) is applied to the drive element (18) which has a limited travel. An appropriately determined proportion of this energy is transmitted to the resilient element (36) which releases it to the pushing element (26). The speed and the acceleration are thus perfectly controlled. The mechanism can also effect the separation of the pieces before ejection. <IMAGE>

Abstract: Dans un procédé et un dispositif pour déterminer la position d'un véhicule routier par saisie et calcul de données sur la marche et finalement par correction de la position calculée en s'alignant sur les données d'un réseau routier digital mémorisé, il est nécessaire de déterminer la position d'une manière fiable. Dans un réseau routier étendu, par exemple de la grandeur d'un pays ou du territoire de la République fédérale d'Allemagne, ceci pourrait conduire à des temps de calcul très longs qui s'opposent à une application raisonnable du procédé. L'invention remédie à cette situation en décomposant à l'aide d'une grille superposée le réseau routier digital en carrés limités en surface, en sélectionnant l'un après l'autre, à partir d'une position de départ, les carrés dans lesquels se trouve la position momentanée du véhicule et en corrigeant à intervalles prédéterminés la position calculée à partir des données sur la marche, afin d'obtenir dans le réseau routier dans chacun des carrés choisis et dans ses environs la position possible la plus probable.

Date Feb. 22, 1990.A metal-clad, compressed-gas insulated, high-voltage switching station with an insulated grounding switch. In the case of compressed-gas insulated, high-voltage switching stations, insulated grounding switches are also used for applying test voltages. Therefore, provided between the housing and the casing is an insulating ring, within which a conductor is embedded with a terminal lug which contacts the contact pin. In order to improve the insulation, the insulating ring reposes within a metallic ring, which acts as a prop ring and which receives the fixing agents. It is only interrupted by the terminal lug which is provided with an insulating enclosure. The insulating ring is thus largely relieved from mechanical stresses. Insulated grounding switches are used in the case of metal-clad, high-voltage switching stations which are insulated by SF6 compressed gas.

Abstract: For forwarding data packets which are transmitted on incoming links (E1,...,En) via virtual connections using an asynchronous transmission procedure and which have a packet header designating the relevant virtual connection via a packet-switching device (PVE) with at least two redundant switching matrices (KV1, KV2) in the direction of outgoing links (A1,..., An) connected to this device, a data-packet group with a number of identical data packets equal to the number of redundant switching matrices is formed through multiplication for each of the data packets transmitted on one of the incoming links via a virtual connection. An identical additional identifier, which changes for successive data-packet groups, is included with each of the data packets of a data-packet group. The data packets of a data-packet group are then transmitted separately via the redundant switching matrices in the direction of the appropriate outgoing link for the relevant virtual connection. Following a transmission of this type, only one of the data packets belonging to a data-packet group is then forwarded with reference to the additional identifier included in each case with the data packets to the appropriate outgoing link. <IMAGE>

Abstract: Method for determining a corrected final value of the wheel speeds of a moving vehicle, an initial value of the wheel speed being determined for each individual wheel during straightline driving. The initial values are different for each wheel, since each wheel has a different dynamic rolling circumference. The initial values are referred to a reference speed, and an individual correction factor is calculated from the deviation of the initial values from the reference speed. Straightline driving is assumed when the initial values of a prescribed number of wheels which are located on different sides of the vehicle lie within a tolerance range. The reference speed is calculated from the mean of those initial values which lie inside the tolerance range. Further devices such as, e.g., steering angle sensors or absolute speedometers are not required. <IMAGE>

Abstract: A device for measuring an air mass having a bridge circuit, in one bridge arm of which a sensor resistor (RS) is arranged in series with a compensation resistance (RK) and in the second bridge arm of which a voltage divider is arranged. The voltage dropping at the sensor resistor (RS) and the partial voltage tappable at the voltage divider are compared to one another in a comparator (K). A single-shot multivibrator (MF) with the constant endurance, by means of the output signal of which a current source (Q) is switched in series with respect to the sensor resistor, is driven by the output signal of the comparator. The bridge voltage is decoupled from the heating current through this arrangement. The air mass flow to be measured can be determined simply from the current flowing in the supply line to the bridge circuit. <IMAGE>

Abstract: It is intended that a wheel bearing, preferably for the wheels of a refuse container, consisting of an axle mounted on a chassis or a container tray, on which axle the hub of the wheel is mounted by means of a holding part provided with an arresting snap-in connection, should be further developed in such a way that it is of simple construction and easy to manufacture and is particularly suitable for axles subject only to a low load and/or only stressed to a small degree. For this purpose, in a wheel bearing an axle (6) which can be inserted into a bracket of the vehicle chassis or of the container wall is provided. It is provided with a bore on its side bearing the wheel (9), said bore having at least one outer section (16) with a smaller diameter and a section (18) with a larger diameter adjoining the latter to form an annular step (17). Moreover, secured in the bore there is a shaft (11) which is provided with a disc-shaped head (10) and, thus, with a thickened end portion (12) at its end opposite the head (10) and with at least one longitudinally extending slot (13) which penetrates said thickened end portion and at least the end portion of the shaft (11). After insertion of the shaft (11), the end portion (12) engages in the bore by means of the springing back, in a snapping manner behind the annular edge (17) of the step, of the resilient legs of the shaft (11) which are formed by the slot (13). Finally, the head (10) has a larger diameter than the outer end region (7) of the axle (6) bearing the wheel hub (8), so that said region at least partially engages over the outer end face edge of the hub (8). The wheel bearing is preferably suitable for the wheels of a refuse container. <IMAGE>
