Abstract: The propagation of interfering higher wave modes in planar branch line couplers, primarily when they are operated in the mm waveband, is largely avoided by those branch arms (VA1, VA2) and/or sections of the connecting lines (VL1, VL2) which are to be dimensioned to a low characteristic impedance consisting in each case of a line (VA11, VA21, VL11, VL21) with an open spur (VA12, VA22, VL12, VL22) branching therefrom, the two inherently having a greater characteristic impedance than the low characteristic impedance which is actually required for the relevant branch arm and/or connecting line section.

Abstract: The invention relates to a process for the disposal of radioactive wastes, in which the wastes are consolidated or compressed and then enclosed in a container. The object of the invention is to improve the process so that the formation of a hydrogen atmosphere in the free gas volume of the container is prevented. This is achieved, according to the invention, by a method in which the wastes are at least partially surrounded by cement containing potassium permanganate in order to eliminate the hydrogen formed during storage. Porous, non-reducing substrate material on the surface of which potassium permanganate is applied is used as an alternative covering material. The waste material and the covering material are placed in a common container.

Abstract: A rotary drill bit is manufactured by forming a main bit body part (16) from a machinable metal, such as steel, machining sockets in the outer surface of the main bit, inserting in each socket a thermally stable cutting structure or former (18) which substantially fills at least the mouth of the socket and projects beyond the outer surface of the main bit body part, applying to the surface of the main bit body part, at least in an area surrounding each socket, a compound (15) comprising powdered matrix-forming material, such as powdered tungsten carbide, mixed with a binder to form a paste, and infiltrating the matrix-forming compound with a metal alloy in a furnace to form a hard matrix. The size, location and orientation of the sockets may thus be accurately determined . using conventional machining techniques, as in the case of an ordinary steel-bodied bit, but the external parts of the bit body are formed of hard solid matrix material and are thus highly resistant to erosion.

Abstract: In the known passive systems, it is conventional for the IR detection optics to be arranged spatially adjacent to the central electronics. However, it is impossible to implement a variable change in the IR reception characteristic. In avoiding this, it is the object of the present invention to develop an IR movement alarm in such a way that it can be integrated in a cost-effective manner and secure against sabotage into a monitoring system having an all-round view. According to the invention, it is proposed in essence that the particular infrared detection optics (1) have a fibre brush (4) of infrared optical fibres (5), which is installed in a first space region (2) and fanned out in the form of a hemisphere over the solid angle 2 pi  steradian, that the central electronics (6) are located in a second spatial region (3) separated from first spacial regions (2), and that the particular fibre brush (4) is connected to the central electronics (6) via a fibre bundle cord (7). <IMAGE>

Abstract: In known large-area support bodies with a metallic base plate and an insulation disc made of a highly thermally conductive ceramic fastened thereto by means of soldering, a buckling of the base plate necessitating expensive finishing work is produced after the soldering process for joining the two materials. The support body according to the invention does not exhibit the buckling, and permits the construction of any component structures with constantly economical production, improvement of heat loss dissipation and also optimum use of the area of the entire insulation disc. The novel support body exhibits an insulation disc divided into pieces, and the metallised insulation disc pieces are fastened on the base plate at a distance from one another and are electrically connected via conductive bridges. The metallisations of the insulation disc pieces are designed appropriately as such. They may be made of copper and be applied by bonding. The insulation disc pieces may bear a structured metallisation. The support body relates to all structures with potential-free fastening of components.
