Title: Dielectric protective hood for microwave aerial of casse grain design - has ellipsoidal cut out between sub-reflector and excitation horn and focus at centre
Inventor: NOTTEBOM GERT ING GRAD
IPC: H01Q19/19
Filed: 1974-09-14
Abstract: The electric protective hood for a microwave aerial is designed according to the Cassegrain principle, where the sub reflector (SR) and the excitation form (E) are relatively close to each other. The hood (H) is formed by an ellipsoidal cut out between the sub reflector and the excitation horn. The first focal point (F1) of the hood is at the phase centre of the excitation system. The second focal point is arranged so that the aperture of the excitation horn is not affected by the reflected radiation to the second focal point (F2). The second focal point is located on or outside the main reflector-edge angle. The junction between hood and sub-reflector is cylindrical and between hood and excitation horn cone shaped.

Title: Alkali cyanide soln. - produced by reacting alkali hydroxide soln. with hydrogen cyanide obtained by thermolysis of formamide
Inventor: SCHWARZ HANS GEORG DIPL CHEM D
IPC: C01C3/10
Filed: 1974-09-21
Abstract: Prodn. of aq. alkali cyanide solns. by reacting alkali hydroxides with HCN, obtained by thermal, catalytically accelerated splitting of formamide under reduced press; is improved in that up to 95% of crude HCN is directly absorbed by an aq. alkali hydroxide soln. without increasing the press. to atmospheric press; whilst the press of the remaining gases is increased to atmospheric press. only subsequently whereby the liquifaction of the residual HCN is effected; the latter is then reacted with the alkali hydroxide soln. The volume of the gases to be compressed to the atmospheric press. is constantly reduced by the absorption of the bulk of HCN when still under reduced press. whereby the size of the compressor can be reduced and the compression cost is dimished.

Title: Nuclear reactor emergency coolant system - with passive pressure-responsive coolant reservoir arrangement
Inventor: KLEIMOLA FRANK W
IPC: G21C15/18
Filed: 1975-02-10
Abstract: Nuclear plant includes a reactor and steam generator sealed in a containment structure and connected by a flow line at a normally constant pressure. The containment structure also encloses a coolant liquid reservoir at a pressure lower than the coolant flow line, and communicating both with the reactor assembly with the steam generator. In a loss of coolant accident, a predetermined pressure drop in the coolant flow line causes liquid to flow from the reservoir to the reactor assembly, and a further predetermined pressure drop between the reservoir and the steam generator results in a flow of steam which pumps liquid from the reservoir to fill the reactor assembly. The system is applicable to pressurised or boiling water reactors using light or heavy water as coolant or moderator. Complete containment is ensured, and emergency operation is wholly passive.

Title: Optical instrument for laser bombardment of microbiological test zones - which is completely independent of parallel displacements and tiltings of beam
Inventor: REMY ERNST DIPL PHYS DR
IPC: B23K26/035
Filed: 1975-02-12
Abstract: An optical laser-microscope instrument for the laser bombardment of microbiological test areas, including a microscope, an operative laser and an arrangement of mirrors for guiding the laser beam to the objective of the microscope, has, as is usual, a second laser generating a beam of a visible wave band, for aligning purposes, which, possibly after diversion, is collimated with that of the operative laser. In the parth of the collimated beam, a beam aligning device is positioned. this has two mirrors which turn the beam through 90 degrees. The mirrors may have a separate reflective coating on their front and rear faces for the wavelengths of the two beams, and they are arranged in a holder so that their front faces subtend an angle of 45 degrees , whilst the line bisecting that angle, intersects the path of the oncoming beams by 45 degrees also. The beam aligner can be turned on two axes at right angles to each other, and intersecting each other in the path of the laser beams. One of these axes is parallel to the bisecting line, and the second mirror can also be turned on two axes at right angles to each other, so that independent parallel displacements and tiltings in small amts., of the beams can be effected, in planes at right angles to each other. Enables layers of laser beams not only to be correctly aligned, but also provides means of ascertaining when the desired alignment has been achieved.
