Abstract: A waveguide arrangement having a longitudinal extension, along which an electromagnetic wave may propagate, and comprising at least one waveguide part and a feeding arrangement which is arranged for feeding said waveguide part with a first polarization and a second polarization, said polarizations being mutually orthogonal. The feeding arrangement comprises a dielectric carrier material comprising a first feeding conductor, feeding the first polarization and a second feeding conductor, feeding the second polarization, where the first polarization is excited by means of first excitation means fed by said first feeding conductor and the second polarization is excited by means of second excitation means fed by said second feeding conductor, where at least one excitation means is a symmetrical structure with respect to the longitudinal extension.

Abstract: A method and an antenna arrangement are disclosed for reducing the antenna radar cross section for an externally illuminating radar source. A radar pulse is transmitted with the antenna arrangement fully matched to achieve a lowest possible power loss of the pulse. At all other times the antenna will be poorly matched and thereby will act as a low radar cross section. The reduced radar cross section leads to an antenna gain reduction, which most often can be accepted since competing noise is reduced as much as the useful signal. It is further suggested that the range gate of the receiver and the transmitter pulse control the antenna. Thus, the antenna is “fully opened” during the transmitting pulse and may be partly or “trade-off” matched during range gate reception. In the interval of not transmitting or receiving, the antenna will present a low radar cross section.

Abstract: The present invention relates to an omnidirectional base station antenna arrangement with a number of antenna elements and a number of transceiver means for transmitting and receiving signals to/from a number of user stations. A feeding network is provided which comprises a number of phase ports, a number of which form first phase ports connected to a number of transceiver means for downlink communication and a number of which form second phase ports connected to a number of transceiver means for uplink communication. The feeding network comprises a number of antenna ports connected to antenna elements and the feeding network generates substantially independent, orthogonal signals to provide for phase diversity and the antenna elements are arranged to form at least one cylindrical array antenna.

Abstract: Process for the manufacturing of slightly soluble or less soluble alkaline salts of substituted sulphinyl heterocycles containing an imidazole moiety with formula I preferably alkaline salts of a proton pump inhibitor compound, wherein the process comprises the step of reacting the substituted sulphinyl heterocycle of Formula I with a source of the cation in the presence of a base, characterized by a washing step in which the prepared alkaline salt of the substituted sulphinyl compound is washed with a basic aqueous solvent mixture. The obtained bulk drug substance resulting in a bulk product that in an aqueous suspension of the substituted sulphinyl heterocycle having a pH not significantly lower than that of a saturated water solution of the pure compound prepared. Alternatively, the process for manufacturing a pharmaceutical dosage form comprising the active substance could be adjusted.

Abstract: An enteric coated oral pharmaceutical formulation comprising as active ingredient a compound selected from the group of omeprazole, an alkaline salt of omeprazole, the (-)-enantiomer of omeprazole and an alkaline salt of the (-)-enantiomer of omeprazole, wherein the formulation comprises a core material of the active ingredient and optionally an alkaline reacting compound, the active ingredient is in admixture with a pharmaceutically acceptable excipient, such as for instance a binding agent, and on said core material a separating layer and an enteric coating layer. A hydroxypropyl methylcellulose (HPMC) of low viscosity with a specific cloud point is used in the manufacture of pharmaceutical formulations. Furthermore, the application describes the processes for their preparation and the use of the claimed formualtions in medicine.

Abstract: An apparatus and method are used for emptying a container in a hygienic (preferably aseptic), for example, aseptic manner. In one embodiment, the device comprises a housing having a first aperture that opens to a first internal chamber and a second aperture that opens to a second internal chamber. The second internal chamber is generally hygienic and opens to a hygienic storage tank or the like at the second aperture. A sealing member is disposed about the first aperture for sealing the container to be emptied over the first aperture. A sterilizing apparatus is provided for rendering the first internal chamber generally hygienic when the container has been sealed over the first aperture. A chamber separating mechanism is utilized to selectively provide fluid communication between, the first and second internal chambers. A cutting member is operable to cut the container in the area of the first aperture to thereby allow the container to be emptied into the first internal chamber.
