Title: Method and apparatus for joining two or more overlapping material members
Inventor: BERGKVIST HANS
IPC: B21D39/02
Filed: 2018-10-19
Abstract: The present invention concerns a method and an apparatus for joining of two or more overlapping material members (A, B). Two or more punches (4.1, 10.1, 11.1, 11.2, 11.5, 11.6) work essentially parallelly and are driven essentially perpendicularly through the overlapping material members, while interacting with one or more dies (4.4, 10.2). The punches have an offset between them in time and thus position with respect to the material members, in such a way that they non-simultaneously will cut out groups of tabs or tongues (5.3) from the overlapping material members. One or more swaging elements (10.3, 11.7, 11.8) are then activated so that each group of tabs or tongues are bent over and compressed against the overlapping material members, whereby the overlapping material members through the swaging are joined mechanically and locked together.

Inventor: BIGGE PETER
IPC: G06F21/62
Filed: 1994-11-29
Abstract: The present invention concerns data base security in a large data base with a large number of users. In a data base having a large number of users belonging to natural client groupings, a unique system administration role can be established for each client, in addition to the central administration role which gives unrestricted access to the entire data base. A client here representing a single organisation, or department, which has a number of data base users, needs to access only some of the value sets stored on the data base, and to perform only some of the available data base applications. The client administration role has access only to those parts of the data base to which the client group as a whole is permitted access. This role allows a client administrator to control access rights of users belonging to the same client grouping, as well as performing sensitive operations, which might involve loss of data, for the client. The client administrator has no control over his own access rights which are controlled by a central administrator.

Abstract: Procedure at cellular mobile telephone system which makes possible for an operator to re-allocate the traffic load from one cell to another at packet switched connections in said system, and reroute mobiles which have GPRS-functionality, to cells which are less loaded. The throughput of data in GPRS is increased by letting the connections utilise several time-slots within the same time-frame. A netowrk controlled "cell re-selection"- algorithm orders the mobile to make a "cell re-selection" to one by the network specified cell, at which the algorithm can be used both at set-up of the data calls and during the session in progress.

Abstract: The present invention utilises direct measurement of marginal critical quantities in direct connection to interesting points in electric power processes in the different electric power objects (10, 12, 14). These points are generally located at places difficult to access, such as on high potential, or at rotating parts (17). The measurements give direct information about actual, now valid operational margins, concerning marginal critical quantities and in particular for quantities that is both marginal critical and material critical. Data about available margins is transferred to other units (32) within the network or plant (1). The electric power plant (1) or electric power network can then be controlled based from such actual operational margins from several different units (10, 12, 14) in the plant (1), which enables a more efficient operation of the plant (1) or network. The measurements give further new paths for detecting faults in the systems. Furthermore, databases of operational conditions can be built, which then can be used both as support for the operation of the system as well as for future maintenance, model building etc.

Abstract: Die vorliegende Erfindung stellt einen Magnetostriktions-Drehmomentsensor zum Detektieren der Lenkkraft zur Verfügung, der eine Magnetismusdetektoreinheit und ein Gehäuse aufweist, das aus einem unmagnetischen, hochleitfähigen Material besteht. Die Magnetismusdetektoreinheit weist einen Spulenkörper auf, der mit Erregerspulen und Detektorspulen versehen ist, und ein Joch in Form eines einstückigen Blocks. Die Magnetismusdetektoreinheit ist in dem Gehäuse angebracht. Durchgangslöcher sind in dem Gehäuse angeordnet, und eine Sensorwelle ist in die Durchgangslöcher über Lager eingeführt. Das Gehäuse verhindert eine Streuung magnetischer Kraftlinien und das Eindringen von Rauschen, um so die Drehmomenterfassungsgenauigkeit der Magnetismusdetektoreinheit sicherzustellen und Energieverluste infolge einer Wärmeerzeugung zwischen der Magnetismusdetektoreinheit und dem Gehäuse auszuschalten. Darüber hinaus werden zu hohe externe Kräfte, die von der Lenkwelle übertragen werden, die mit der Sensorwelle und der Lenkausgangswelle verbunden ist, von dem Gehäuse über die Lager aufgenommen, wodurch eine Auswirkung auf die Magnetismusdetektoreinheit ausgeschaltet wird, was es ermöglicht, die Drehmomentmeßgenauigkeit zu stabilisieren.

Abstract: The method involves detecting the linear displacement of a valve closure element (6) using a sensor (16), and processing the sensor signals (19) in an electronic evaluation unit (12) to determine pref. displacement, speed or acceleration and deviations between a demanded motion and an actual motion of the closure element. The determined deviation is converted according to a defined characteristic into a control value (20) for a damping element (11) variable by an external energy source. The control value is applied to the damping element. The actual motion of the closure element can be compared with a characteristic field of values for the demanded movement.

The membrane (14) is selectively permeable in such a way that a measuring mixture is formed in the measuring chamber (16) in which the alcohol concentration is less than 1 vol.- % or more than 5 vol.- %. Suitable fuel sensors (17) can be used for said concentration ranges. The invention also relates to the operation of fuel cells using alcohol or ether as fuels, and water.
