Abstract: A differential transmission transition interface is disclosed which can include first and a second buried conducting tracks providing respectively first and second differential couplings between a differential RF transmission output and a waveguide; the first buried conducting track extending over an opening of the waveguide to provide a first RF coupling element; and the second buried conducting track extending over the opening to provide a second RF coupling element. At least a portion of the first RF coupling element extends over the waveguide opening in a first angular direction; and at least a portion of the second RF coupling element extends over the waveguide opening in a second angular direction that is opposed to the first angular direction.

Abstract: A planar Vivaldi antenna array, and method of forming such an array, the array comprising: a plurality of slots at an end of the antenna array, the slots extending through the whole thickness of the planar structure of the antenna array; and a plurality of grooves extending from the slots; wherein: the grooves do not extend through the whole thickness of the planar structure of the antenna array; and the cross-sectional shape of the grooves is complementary to the cross-sectional shape of the slots.

Abstract: An electrical generation system. A floating vessel is anchored in flowing water. Inlets in the hull of the vessel capture flowing water and direct the water to one or more turbines. The system is designed so that all flows are two-dimensional to the extent possible. The latter feature greatly simplifies both design and construction.

Abstract: An apparatus and method are provided for applying a fixed non-linear profile of power (amplitude) and delay to signals across the aperture of an array antenna having multiple antenna elements where multiple beams are formed to span the field of view of the antenna. Using such fixed profiles in combination enables a substantially constant beam width to be maintained across a wide range of operational frequencies, e.g. 6-18 GHz, ensuring that the points of overlap for adjacent beams does not drop below a certain level, e.g. ?3dB, and hence maintaining a substantially uniform coverage across the field of view of the antenna at all frequencies in the range.

Abstract: A multi-additive injection system for injecting required amounts of different additives to flowing fuel in a fuel line (6) comprises a number of additive injection sub-systems (1, 2, 3 and 4). Each sub-system includes a source of additive (7), a pump (13) to deliver additive from the source (7) to the fuel line (6), and an additive meter (21) to measure an amount of the additive being delivered to the fuel line (6) by the pump (13). The multi-additive injection system further includes a meter to measure the amount of fuel flowing through the fuel line (6) and a control device such as a computer to control the pump (13) of each sub-system to adjust the amount of additive being delivered by each pump, should the amount metered by the meters (21) deviate.

Abstract: Device and method for drying a pourable products. The device includes a rotor chamber in which a rotor is arranged with a vertical rotor axis. The rotor has a central horizontal surface and, at least in its radially outer third, a conical shell which is inclined to the axis of rotation by 20° to 70°, in such a way that the end face of the conical shell has the largest diameter and is located at the top. The conical shell has, at least partially, sheet-like gas passages in the form of perforations or screens. The method for drying pourable products provides for dry gas to be fed in a sheet like manner to the products to be dried during the radially peripheral circulation of the products without the products being swirled up and being exposed to unacceptable compressive, concussive and/or frictional loads.

Abstract: Device for producing a pourable product with a guide vane therein and method for using the device. The device includes a rotor chamber in which a rotor is arranged with a vertical rotor axis. The rotor has, at least in its radially outer third, the shape of a conical shell. Guide vanes for circulating starting materials or the product are arranged statically on an inner wall of the rotor chamber above the plane of the upper edge of the rotor. The guide vanes have, in cross section to the rotor axis, essentially the shape of a segment of a circle or spiral. The inner ends of the guide vanes lie approximately in the middle part of the rotor radius. The conical shell may have at least partially sheet-like gas passages in the form of perforations or screens. The device is used for producing pourable products.

Abstract: A continuous mashing process for producing wort in the production of beer comprises providing a mash mixture of malt and raw grains; continuously flowing the mash mixture through a mash reactor; and heating the mixture during its flow through the reactor to progressively raise the temperature of the mixture at an almost constant temperature gradient from approximately 30.degree. C at the reactor inlet end to approximately 80.degree. C at the reactor outlet end to thereby form mash. During its flow through the reactor, the mixture is agitated in a controlled manner to effectively prevent overheating thereof and facilitate the extraction and diffusion of the active ingredients in the mixture, and the agitation is carried out so as to prevent back-flow of the mash within the reactor. The mash is then filtered to produce wort.
