Title: High frequency electromagnetic wave transmitters
IPC: H03B5/10
Filed: 1935-05-01
Abstract: 436,641. Valve amplifying circuits. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. May 1, 1935, No. 12961. Convention date, May 3, 1934. [Class 40 (v)] A high-frequency transmitting amplifier employing ironcore transformer couplings K is given an even transmission characteristic despite changes in the operating frequency by utilizing the flow of grid current in one stage R2 to provide grid bias correction for a preceding stage R1. Owing to resonance effects at certain frequencies the voltage swing on the grid of the stage R2 rises, causing heavier grid current to flow in the resistance W1, and applying a greater negative bias through a resistance W2 to the grid of the valve R1, thus tending to keep a flat transmission characteristic.

Filed: 1965-03-31
Abstract: Olefins are oligomerized in the presence of an activated cobalt on carbon catalyst obtained by bringing cobalt metal or an oxide of Co, deposited on activated carbon into contact with N2O4 at temperatures not exceeding 500 DEG  C. The reaction is preferably effected in liquid phase either by using sufficient pressure to liquefy reactants or by use of solvents, e.g. pentane or hexanes.  Specified olefins to be oligomerized are ethylene, propylene, butenes, pentenes and mixtures.  A long list of oligomeric products from propylene is given, chief of which are cis- and trans-4-methylpentene-2 and cis- and tranx-hezene-2.ALSO:Co or CoO on carbon catalysts are activated by contact with N2O4 at temperatures not exceeding 500 DEG C.  In lieu of N2O4, decomposition products e.g. NO2 and NO or precursors therefor e.g. N2O5 may be used.  The treatment may be effected in the presence of an inert gas as carrier for the N2O4 or steam.  The N2O4 may be used in gaseous or liquid phase.  In examples the activation is effected in a fluidised bed.

Abstract: 889,381. Analogue computers; deriving trigonometrical functions. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 21, 1958 [April 30, 1957], No. 13791/57. Class 37. A computer particularly for use with positioning devices using zig-zag inductances derives voltage analogue signals proportional to the sine and cosine of a desired angle by the addition of terms involving trigonometrical functions of partial angles which together equal the desired angle and feedback signals from the output of the computer are employed in the formation of at least one of said terms. In the embodiment shown in the Figure, A, B, C are three angles the sum of which is equal to the desired angle, transformers being used to perform the computation. An auto-transformer T1 is energized by a reference A.C., ganged contactors C1a, Clb selecting analogue signals of sin A, cos A respectively which are applied across two further autotransformers T2, T3, tapped for values of tan B by contacts C2a, C2b so that the voltages induced at these contacts are sin A tan B, cos A tan B. The output voltages at P, Q are proportional to Vs, Vc, the amplitudes of the voltages across primary windings T6a, T7b of output transformers T6, T7. Extensions T6b, T7b of these primary windings are tapped by contacts C3a, C3b for values of - tan C which provide the feedback signals, so that the voltages appearing across the primaries of T4, T5 are (cos A tan B+ Vc tan C) and -(sin A tan B+Vs tan C) respectively which are added in these transformers to sin A and cos A. It is proved in the Specification that Equations of the general form Vs = f (A, B, C, Vc), Vc = g (A, B, C, Vs) may be solved by the computer, and if the computer is used with a positioning device employing zig-zag inductances, A+B+C represents on the angular scale of the inductance the displacement of the movable part required, Vs Vc being the quadrature trigonometrical function required.
