Abstract: A method and means for diagnosing transformer tap changers is provided. Pressure is monitored in an insulating liquid of a tap changer for a period of time in which switching of the tap changer is carried through. Switching-related information is extracted from the pressure diagram. Quantities from pressure peaks are related to specific arcings of the switching sequence. Early error detection is achieved, whereby transformed failures may be avoided. Repeated measurements may be followed by trend evaluation. If a trend indicating tap changer problems is detected, an alarm signal is triggered. The transformer may be switched off if the pressure exceeds a predetermined emergency value. Information of the base pressure in the tap changer may be extracted and converting it to level of insulating liquid.

Abstract: A method and apparatus for condition diagnosing of a tap changer immersed in a cooling fluid, controlling and regulating an inductive power device, such as a transformer or reactor. The diagnosing method compares and evaluates expected heat exchanges between the tap changer and ambient air and the inductive power device, an expected amount of heat generated by the tap changer during operation, together with an actual temperature of the fluid. From the actual temperature, expected heat exchanges and expected generated heat, the heat balance in the system may be obtained and is used for disgnosing the operation conditions of the tap changer. The results from the condition diagnosing may be used as indicators that can alarm operators or may be sent as a data signal to remote and/or portable display means, such as a computer.

Abstract: A method and means for diagnosing transformer tap changers is provided. Pressure is monitored in an insulating liquid of a tap changer for a period of time in which switching of the tap changer is carried through. Switching-related information is then extracted from the pressure diagram. The method, preferably used for single-phase tap changers, comprises the step of relating quantities from pressure peaks to specific arcings of the switching sequence. Early error detection is achieved, whereby transformed failures may be avoided. Repeated measurements ae followed by trend evaluation. If a trend indicating tap changer problems is detected, an alarm signal is triggered. The invention may include switching off the transformer if the pressure exceeds a predetermined emergency value as well as extracting information of the base pressure in the tap changer and converting it to level of insulating liquid.

Abstract: A device for storing and administering a medical fluid comprising a sealed flexible formed container with an opening part in its front end in which an insert is positioned. Over the insert, the container extends into a removable sealing cap. After removal of the sealing cap an injection means is attached to the insert and fluid administration through the insert is admitted in one direction by squeezing the container.

The present invention also relates to medical containers made of or comprising the above film.

Abstract: The present invention discloses a method and apparatus (4) for condition diagnosing of a tap changer (1) immersed in a cooling fluid (3), controlling and regulating an inductive power device (5), such as a transformer or reactor. The diagnosing method basically compares and evaluates expected heat exchanges between the tap changer (1) and ambient air and the inductive power device (5), an expected amount of heat generated by the tap changer (1) during operation, together with an actual temperature of the fluid (3). From the actual temperature, expected heat exchanges and expected generated heat, the heat balance in the system may be obtained and is used for disgnosing the operation conditions of the tap changer (1). The results from the condition diagnosing may be used as indicators (70) that can alarm operators or may be sent as a data signal (78) to remote and/or portable display means (79), such as a computer.

The port comprises a cap in its front end which axially extends into an essentially sleeve formed part provided with said penetrable membrane which is scaled from contamination by said cap and furthermore it is provided with means to expose said penetrable membrane when it is desired to establish fluid communication with the container.

Abstract: The invention relates to a process of preparing pharmaceutical closures for containers made of flexible polymeric materials which are suitable to be filled with parenterally administerable fluids prior to their scaling and sterilization. The process involves a specific relaxation period for the elastomer material of the closure which thereby can settle and develop resealing characteristics. The closures will have an excellent resealing capacity after being penetrated by a piercing device for establishing fluid communication with the container, even after multiple entries into the container.

Abstract: A device for influencing light has a polarizer, a ferroelectric or electroclinic response type liquid crystal halfwave plate whose liquid crystals are in the smectic phase with bookshelf geometry and have molecular axes which are rotatable around a first direction corresponding to the direction of incoming light in response to an electric field applied across the electrodes on either side of the halfwave plate, a quarter wave retarder plate, and a mirror. The polarizer, plates and mirror are arranged such that incoming light is passed from the polarizer through the liquid crystal plate and the retarder plate, and is reflected by the mirror in a second direction opposite to the first direction back through the retarder and the liquid crystal plate so as to provide a reflected polarized light plane to the polarizer.
