Title: Horn aerial for orthogonal polarised EM radiation - has coaxial cable connected behind outer and central guides forming channels for wave combination zone
Inventor: MEINKE HANS HEINRICH PROF DR D
IPC: H01Q13/02
Filed: 1980-03-13
Abstract: The horn aerial has a central conductor (1) shaped to combine the two waves (W1,W2) so that they are combined to travel in the same direction. The coaxial conductor is connected to a feed zone (Q3) at the rear, with the inner and outer conductors (11,9) connected respectively with the inner edges (B2,B1) of the wall (2) of the horn. The radiation is then guided between the guides (6,7) attached to the inside of the horn and the curved sides of the central conductor (1). This conductor has curved sides which follow the shape of the interior of the horn approximately to terminate in a steeply sloping end at a zone (Q1,Q2) short of the ends of the guides. The two waves start to combine within this zone and completely combine beyond the ends of the guides.

Patent DE-3014481-A1 (DE)
Inventor: WALSER PETER
IPC: F24H1/10
Filed: 1980-04-16
Abstract: There is a problem of the comparatively high vapour content in the exhaust gas in the case of hot gas/liquid heating systems having direct contact between a hot gas (2) and a primary heat exchange liquid (5) which in this case is at least partially evaporated and dissipates the heat content absorbed in this way by condensation and return to a heat utilisation system (100). To solve this problem, for the purpose of additional dissipation of heat relative to the primary heat carrier return (5b, 7) a heat exchanger (14) having a secondary heat carrier medium (7a) which is separated from the hot gas by thermally conductive walls is arranged downstream, in the direction of the hot gas flow (2), of the direct heat transfer region (4). This permits a reduction in the exhaust gas vapour content without an excessive supply of heat exchange liquid which can give rise beyond the vapour saturation of the exhaust gas to entrainment of finely dispersed liquid and thus to a loss of heat. <IMAGE>

Title: Plug-connector socket for connecting pins
Inventor: SADO RYOICHI
IPC: H01R11/01
Filed: 1981-02-09
Abstract: The plug-connector socket, which is used especially for connecting a male connector strip to the connecting contact female connector strip on a circuit board, especially for populating circuit boards with components, consists of a socket body having anisotropic electrical conductivity and in which retaining grooves are constructed for holding the connecting pins of the male plug. The anisotropic electrical conductivity of the socket body is maintained by embedding numerous electrically conductive linear conductor elements in an elastomeric matrix consisting of an electrically insulating material. The linear conductors are electrically insulated from one another in the matrix and are aligned at least essentially parallel to one another and at least essentially at right angles to the longitudinal axis of the socket body, which is preferably in the form of a strip. The retaining guides are arranged at right angles to the linear conductors, to be precise in such a manner that at least the cross-sectional surface of an electrical conductor is exposed for electrical connecting purposes in the inner wall of each individual retaining guide, that is to say can make electrical contact with a connecting pin which is inserted into the retaining guide. If the plug-connector socket is used for producing electrical connections to circuit boards, the cross-sectional areas of the conductors are also exposed in one of the side surfaces of the socket body by means of which this is then laid on the connecting contact female connector strip of the board and is electrically conductively connected thereto.

Patent DE-3118789-A1 (DE)
Title: Solid propellant rocket engine with variable thrust
Inventor: KATSUAKI KOSAKA
IPC: F02K9/26
Filed: 1981-05-12
Abstract: The invention relates to a solid propellant rocket engine which is designed in such a way that it can temporarily increase its thrust at a required stage of its operation. The engine has a first propellant structure which is fixed in the combustion chamber and is designed with a hole, which intersects an initial combustion surface of the structure, and a second propellant structure which is fitted displaceably and gas-tightly into the hole of the first structure and is shorter in length than the said hole. Initially the second structure is prevented from moving relative to the first structure by a retaining mechanism which, for example, comprises a piston, which extends into an end section of the said hole and comes into contact with one end surface of the second structure. At a desired point during the operation of the engine the retaining mechanism can be disabled by actuation of a release device, the second structure being forced to move by the combustion gas pressure with the result that one end section of the inner surface of the first structure, which forms the hole, is exposed and becomes an additional combustion surface. The two structures are generally formed and arranged in such a way that they form one structure essentially burning endwise. <IMAGE>
