Title: Telephone exchange with central control - interrogating de-centralised devices so that relay control data is handled before flip=flop control data
Inventor: KRAUSS JULIA
IPC: H04Q3/54
Filed: 1978-03-28
Abstract: The telephone exchange is designed so that higher priority main operations are evolved at the right time and lower priority main operations are not delayed unduly. The different times needed to execute these operations are taken into account, e.g. flip-flops respond quicker than relays. A central control interrogates decentralised devices and fetches information from them which it uses to control the operation. Interrogation takes place in a time interval divided such that the central control manipulates information for use in controlling, e.g. relays during the first half of this interval whilst in the second half it manipulates information for controlling flip-flops.

Title: Monocrystal block with conical void esp. for armour-piercing charge - is grown from pref. copper seed crystal using pref. tungsten former
Inventor: BETHMANN KARL WILHELM DIPL ING
IPC: F42B1/036
Filed: 1978-03-30
Abstract: The parent patent describes a method of making a blank for a rotationally symmetrical hollow object, esp. having a conical void and intended for the hollow charge of an armour-piercing projectile. Monocrystalline solidification of a material is used. In the patent of addn., a given volume of the required material, pref. copper, is first melted and then is progressively solidified at a solid-liq. interface or front initiated by a seed crystal. This front advances along an axis from an initial or starting ordinate (s) to a final ordinate (3), and the shape of the required conical void is defined by a conical shell, pref. of tungsten, having its axis coincident with the growth axis. The starting point of the conical void, i.e. the apex of the cone, lies between the two ordinates (s) and (e). Thus during the entire process, the solid-liq. front adjoins (at annulus) the solid-solid front between the solidifying copper and the tungsten former. Used for armour-piercing projectiles, where monocrystalline copper is frequently used. The process and appts. described enable a conical void to be produced in the monocrystal.

Patent DE-2921825-A1 (DE)
Title: Hydrogen diffusion preventing phosphate glass coating for metals - formed using esp. phosphoric acid soln., useful for coating nuclear reactor piping
Inventor: MCGUIRE JOSEPH CLIVE
IPC: H01M8/02
Filed: 1979-05-29
Abstract: Hydrogen diffusion through metal is reduced by coating the metal surface with a phosphate radical-contg. phosphate glass-forming material and heating to >=350 degrees C to form the glass. The method is esp. useful for preventing diffusion of radioactive tritium through the walls (e.g. of stainless steel) of primary fluid-contg. appts. of a nuclear reactor (esp. a fast breeder or fusion reactor). The method can also be used to reduce hydrogen embrittlement or reduce leakage in a H2-O2 fuel cell. The phosphate radical reacts with metal oxides or metals at the surface being coated to provide a self-cleaning action and form an adherent glass coating. In the case of reactor piping (e.g. fast breeder reactor piping operating at about 550 degrees C), the glass can be formed on the piping in situ using heat from reactor operation, thus obviating the need for special furnaces. At operating temp. in reactor piping, the glass softens so that cracking is avoided during temp. cycling.

Title: Colour film copying via colour separations - by print out on black and white film developed in presence of coupler and bleached at each stage
Inventor: HOVESTADT ANSGAR
IPC: G03C7/00
Filed: 1979-07-25
Abstract: In a colour film copying process, 3 colour sepns., with additive basic colours, are produced from the original. One of these is exposed on a black and white film material yielding the later copy and this is developed with a soln. contg. a colour coupler to give a colour print of the complementary colour in the emulsion. The film is then bleached, i.e. the Ag formed is oxidised to Ag halide again. The exposure, colour print formation and bleaching stages are then repeated for the other 2 colour sepns. A large number of films can be copied very economically. Development is simplified, since the permissible tolerance of developer concn. and bath temp. is greater than usual. The copy definition and contrast are also improved.
