Abstract: 836,812. Making grids for electron discharge devices. TELEFUNKEN G.m.b.H. July 9, 1956 [July 9, 1955], No. 21139/56. Class 83 (2). A method of making a grid, e.g. for a klystron valve, comprises stacking layers 1 of a material to form transverse slats interleaved with spacing material, enclosing the stack with a metal to form a frame joined to the longitudinal edges of the layers and then removing the spacing material. Spacing members 1, e.g. of iron, are coated on both faces with a layer of slat material 2 e.g. copper, silver, &c., stacked together and formed into a unified block by uniting adjacent layers by pressure and/or by heat. Where unification involves heating the spacing material may be coated on to the layers of slat material. After any desired shaping of the block such as curving, a rod is turned from it, Fig. 4, and coated, e.g. by electroplating with copper, or other material more resistant to heat or acid than the spacing members, to form a frame. Circular discs are then cut from the rod and ground to the required thickness as shown in Fig. 6, and the spacing members are removed by etching out or dissolving e.g. iron is removed by etching with muriatic acid. Alternatively aluminium spacing members may be used and removed by melting. Machining of the block may be avoided by preshaping the spacing members and slat layers. In a modification, instead of merely being coated, the rod may be soldered in a thick-walled cylinder from which discs are cut and grids produced as before. In another modification the slat thickness and spacing of the grid is controlled by the application of a pressure sufficient to cause lateral flow during unification of the block. The grids may be rectangular or square in addition to the circular form.

Abstract: 1,145,878. Logic circuits. ELEKTROAPPARATE-WERKE BERLIN TREPTOW, VEB. 12 May, 1966, No. 21158/66. Heading H3T. A fail-safe logic circuit has the input signals applied to two electrodes of a transistor and a pulse train to the third electrode, the output being a pulse train which ceases if a component fails. Fig. 4 shows a BUT NOT circuit in which the inputs S1 and S2 are represented by switches 9, 11 which apply - Uv or O v  to the collector and emitter respectively. A pulse train X T  applied to the base is received at A only for the input states represented by 9 being open and 11 closed, and failure of a component can only give a steady potential at A. In Fig. 5 (not shown) three circuits as in Fig. 4 are connected in series to give an output representing S1.#S2.S3.#S4.S5.#S6. Voltage dividers (14/15, 14/16, 14/17) attenuate the pulse train so that the output depends on the amplification property of the transistors and will not appear erroneously if a transistor short-circuits. The resistances may be non-linear, e.g. diodes or Zener diodes. In Fig. 6 (not shown) two circuits as in Fig. 4 are connected in parallel to give an EXCLUSIVE OR function. The output is taken via an amplifier and a push-pull transformer (33) so that if one of the amplifying transistors (29-31) fails the other side still passes enough signal. The transformer output is rectified by a diode bridge (35) and feeds a control member (36), e.g. in railway safety equipment or a nuclear reactor.
