Abstract: The power chuck is particularly intended for holding crankshafts. The chuck has a base, a head, and clamping jaws. The head is radially guided with respect to a clamping axis which extends parallel to an axis of rotation. The clamping jaws are connected to a drive piston by way of axially movable wedge members which can be axially displaced in the base. The chuck also has a holding body which is reciprocatingly guided at the base. When considered in transverse direction with respect to its direction of displacement, the holding body has a width which is smaller than the diameter of the base. Parallel thereto and on both sides of the holding body are arranged movably guided counterbalancing elements, and they are each connected by way of a gear wheel in a countercurrent manner to the body. Several clamping jaws are separated into an inner part and an outer part, of which the inner part is guided in the holding body, and the outer part with the wedge member connected to it is guided in the base. Both parts are operatively connected by way of a dovetail slide connection which extends parallel to the direction of displacement of the holding body.

Abstract: Die Erfindung betrifft eine Schaltung zur Verringerung der Verzerrungen bei einem FM-Quadraturdemodulator. Sie sieht vor, daß dem Quadraturdemodulator eine nichtlineare Schaltungsstufe nachgeschaltet ist, deren Kennlinie den inversen Verlauf hat wie die Demodulator-Kennlinie. Wenn der FM-Quadraturdemodulator zur Erzeugang einer frequenzabhängigen Phasendrehung einen Resonanzkreis benutzt und zwei gegenphasige Ausgänge aufweist, kann die nichtlineare Schaltungsstufe durch zwei von den Ausgangsströmen des Quadraturdemodulators durchflossene Diodenzweige gebildet werden, wobei die Spannungsdifferenz au den zwei Diodenzweigen das von nichtlinearen Verzerrungen weitgehend befreite Ausgangssignal ergibt.

Abstract: A bipolar transistor R.F. power amplifier in which feedback is used to control simultaneously amplitude and phase distortion. 
     The bipolar transistor R.F. power amplifier is operated by determining a set of collector supply voltages located at the onset of gain saturation in the bipolar transistor and using feedback to adjust the collector supply voltage in response to variation in input drive level to operate the bipolar transistor in a mode where gain, phase shift and input impedance are simultaneously linearised, found at the onset of gain saturation. 
     A circuit for determining the selection of collector supply voltages comprises oppositely polarised diode detectors (36, 38) which are connected to the input and output circuits of the amplifier (24). Outputs of the diode detectors (36,38) are applied to a differential amplifier (44) which controls a modulated power supply unit (46) for varying the collector voltage. Preferably the power supply unit is a switched mode power supply unit.

Abstract: The catalyst activates the setting of cements, limes and plasters and consists of colloidal sulphur in a quantity of at least 83%, sodium thiocyanate at least 0.2%, sodium thiosulphate at least 0.2%, phenol at least 0.1 %, benzene not exceeding 0.3% and naphthalene not exceeding 0.4%. 
     The method for producing this catalyst consists of the direct oxidation of hydrogen sulphide containing added naphthalene, ammonia, hydrogen cyanide and aromatic hydrocarbons in the presence of catalyst in the form of hydroquinone and sodium carbonate, which disperses the elemental sulphur formed down to the colloidal level. 
     The result of the action of the catalyst according to the invention is a limitation of excess mixing water, fluidization and plasticization of the concrete mass and imparting of thixotropic properties thereto. Moreover it contributes to increase the mechanical strength of the concrete, its impermeability, and to improve the corrosion resistance after the cement hydration period.
