Abstract: A digital background normalizer system for detecting a point signal or pixel value under test in a background area which is scanned to provide video signal that are converted into digital form. In orderto accumulate by digital integration techniques, the total accumulated signal over a background window is squared by multiplier (20) prior to integrating (22) the volume under a curve which is bounded by the background window area, thereby accumulating the pixels in the complete background window area. Separately, the squared video signal is integrated (24) over a selected smaller central window around the pixel value under test. The accumulated values of the central window are subtracted (28) from the accumulated values of the complete background window to obtain a net accumulated signal value. A mean squared value of the net background accumulated signal (34) is obtained by dividing it by the number of pixels located over such net background window. Next, a root means square (RMS) noise value (38) in the background of the pixel under test is generated from the mean squared value. The RMS value provides the threshold value which is compared with the actual pixel signal under test for detecting if the pixel signal is above the threshold value. The threshold value can thus be continuously changed in accordance with the level of detected background noise.

Abstract: A sliding roof for a motor vehicle has a rigid panel (20) closing an opening in the vehicle roof and which can be opened either by sliding the panel rearwardly below the vehicle roof (14) behind the opening or by pivoting the panel upwardly about a transverse horizontal axis adjacent to its front edge so that the rear edge of the panel is above the vehicle roof (14). Each side of the panel (20) is supported at the rear on a sliding shoe (30) and lift means (42), the sliding shoe (30) being connected by spacer means (68) to corresponding support means (28) for the front edge of the panel (20). The lift means (42) comprises a pair of semi-flexible strip elements (44, 46) each of which has one end secured to the underside of the panel (20) and the other end projecting into a respective longitudinally extending channel formed in the rear shoe (30), one of said channels extending forwardly and the other extending rearwardly. The end of the strip element (44) in the rearwardly extending channel is connected to drive means (60). The flexibility of the strip elements (42, 44) is such that, when the drive means (60) causes forward movement of the rearwardly extending strip elements (44) with the rear guide shoes (30) restrained against forward movement, both strip elements (42, 44) move outwardly from their respective channels in the two sliding shoes (30), thereby lifting the rear edge of the roof panel (20).

Abstract: Vorrichtung zur Erzeugung einer nahezu punktförmigen Plasmaquelle mit hoher Strahlungsintensität im Röntgenbereich. Von einer zylinder förmigen Innenelektrode, die konzentrisch von einer zylinderförmigen Außenelektrode umgeben ist, wird ein einseitig offener, gasgefüllter Entladungsraum gebildet. Dieser ist am geschlossenen Ende direkt mit einem niederinduktiven Hochleistungsschalter verbunden, der zur kurzzeitigen Verbindung der Elektroden mit einem elektrischen Energiespeicher dient. Die Innenelektrode ist am geschlossenen Ende des Entladungsraumes konzentrisch von einem Isolator umgeben, der einen hohen Sekundärelektronenkoeffizient hat. Diesem Isolator steht eine auf dem Potential der Außenelektrode liegende ringförmige Emissionselektrode gegenüber und zwar in einem Abstand, der kleiner ist als die freie Weglänge im Gas des Entladungsraumes. Es entsteht in definiertem Abstand von der Emitterelektrode eine Gasentladung im Entladungsraum, welche die Form einer homogenen Plasmaschicht hat. Diese bewegt sich zum offenen ende des Entladungsraumes und bildet dort einen Plasmafokus mit außerordentlich hoher Teilchendichte und kleinem Durchmesser, der eine Röntgenstrahlungsquelle darstellt.

Abstract: A microwave balun using TEM wave guides, consists of two second-order reactance sections of electrical lengths equal to about a quarter of the wavelength of a radiofrequency signal comprising an unbalanced input-port and a balanced output-port. Each section (I, II) comprises two strips of microstrip-like wave guides, placed in such a way above the ground plane being the bottom metallization (0) of the lower layered substrate (3) that one of the guides (1, 2) is on the top side of the lower substrate, and the other guide (1', 2') placed thereabove is separated therefrom by the material volume of the upper layered substrate (4) and is on the top side of the upper substrate. The pair of guides, any one from each section, being the pair of input guides (1, 2) is connected with each other by two ends (12, 21), while one of the two remaining ends (11) thereof is connected to the input-port (10), and the other one (22) is terminated for a radio-frequency signal by a reflecting element. The second pair of the remaining wave guides (1', 2') being the pair of output guides, forms with two ends (12', 21' ) thereof, one from each section, a pair of output-port terminals. Each of the remaining ends (22', 11') of the pair of output guides is terminated for a radio-frequency signal by a reflecting element, whereby phases of the said reflecting elements are dependent on the configuration choice of the input and the output-ports and the phase choice of the reflecting element terminating the end of input guides, the opposite one to the input. The cross-section dimensions and material constants of materials used have the values dependent on the required broadband properties according to the set of transmission-reflection parameters of the balun and the required input and output impedance. The balun design according to the invention is designed for utilization within the frequency range of 1-18 GHz.

Abstract: An oil-spill-combatting water craft is provided with at least one protruding boom (9) but most suitably one on each side of the craft, the booms directing surface water and oil present in it into a conduit (2) inside the craft (1), the inlet (8) and the outlet (7) of the conduit being located in the side of the craft. The purpose is to provide a simple, high-capacity arrangement in which the flow is, nevertheless, relatively calm also when the sea is rough. With this in mind, the conduit has been implemented as a circulation conduit the outlet of which is situated towards the bow from the inlet and in which the water flows automatically owing to the water-raising and water-guiding effect of the boom (9). The separating means for water and oil, fitted inside the conduit (2), is a rotating arrangement (4) which allows water to flow through and is, for example, made up of rows of bristles. In front of the outlet (7) of the conduit there is fitted a baffle (6) which extends obliquely outwards and backwards.
