Filed: 1935-06-07
Abstract: 445,071. Valve modulating circuits. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. June 7, 1935, Nos. 16595 and 16596. Convention dates, Feb. 5 and April 24. [Class 40 (v)] The degree of modulation in a radio beacon transmitter is maintained constant by controlling the bias of the modulating or a preceding stage. The Figure shows a rectifier G, biassed to obtain a delay voltage and fed from the output which controls over a filter the bias of amplifier II. In a modification, Fig. 2 (not shown), part of the non-modulated carrier is rectified and used for bias control since constancy of amplitude of the tone modulation frequency is readily ensured. In the latter arrangement a three electrode rectifier is employed the potential being applied to grid and anode while the grid is given a separate bias potential so that the rectifier working point can be adjusted to obtain a delay voltage independently of the amplifier bias. The rectifier bias may be controlled in dependency with the modulation tone or with the supply voltage.

Filed: 1976-04-30
Abstract: 1518228 Conical refiners TMM KOUACHI and J H YOUNG 30 April 1976 17641/76 Heading B2A [Also in Divisions D2 and G3]  In a refiner for papermaking of the type comprising two relatively rotatable surfaces 10, 12 which are urged together by a constant force but kept apart by circulating fibrous material, the gap G between the surfaces is continuously measured when in operation. It is explained that the density of the finished paper is a function of this gap, and it is desired to keep this constant. This may be effected manually in response to the measurement displayed at 40, but as shown the measurement signal operates a flow control valve 76 on the outlet of the refiner, adjustment of which causes alteration of the gap. In an alternative embodiment (not shown) the fibrous material is recirculated through the refiner at constant pressure until the initially wide gap reduces to the desired value. The gap is measured at 34, 36 by the axial displacement of the shaft 8 with the rotor 6, either electrically by capacitive or inductive (differential transformer) effects, pneumatically by a back-pressure device or by an unspecified hydro-electric transducer. The valve 76 may be operated electrically, pneumatically or hydraulically. The constant force is applied by weighted levers, with an adjustable stop to limit travel (Fig. 4, not shown). Both surfaces of the refiner carry blades which cut, crush and bend the fibres to improve their flexibility.
