Abstract: Stereo decoder for multiplex signals comprising a demultiplexer for decoding the left-hand and the right-hand sound signal of a stereo multiplex signal, a phase-locked loop which includes a phase-locked oscillator and a multiplicative phase detector, and a pilot elimination circuit, for reducing the pilot signal of a multiplex signal, which is used in two manners, namely, to suppress the pilot signal in the decoded left-hand and right-hand sound signal at the sound output of the demultiplexer, and to suppress disturbances in the frequency control of the phase-locked oscillator caused by sound components of the multiplex signal. To this end the phase detector comprises a differential reference input stage to which on the one hand the complete stereo multiplex signal is applied and on the other hand, in phase (common mode) therewith, the output signal of the pilot elimination circuit, that is to say the stereo multiplex signal with the suppressed pilot signal.

Abstract: A sliding gate valve of the type in which refractory gates (17, 17') are sequentially disposed in operative position beneath the pour opening from a teeming vessel, such as a tundish, is effective to throttle the metal flow stream from the vessel. Means (84) for positioning the gates in order to control the degree of throttling of the flow stream are independent from the means (74) for disposing the gates in their working position within the valve mechanism whereby the flow stream can be terminated without adjusting the throttling configuration of the valve. Means are provided, when the valve employs a pour tube (19) attachment, for selectively changing gates and pour tubes in unison, or independently from one another. The valve mechanism and its replaceable refractory components are designed for the supply of fluids for cooling these members and for the injection of inert gas to stir molten metal in the flow passage during holding periods. <IMAGE>

Abstract: A power module assembly in the form of an electrochemical battery which is composed of a plurality of anode-cathode units arranged in stacked relation within a housing. It is necessary that the anodes and cathodes be tightly pressed together at all times so that as an electrolyte flows therebetween there will be the desired electrochemical reaction. This is accomplished by a pressure device. Since the anodes are consumable, as the anodes are consumed it is necessary that the stack be compressed to that the same pressure may be maintained between the anodes and cathodes. Accordingly, the pressure device is capable of expanding and at the same time transmitting constant pressure on the stack.

Abstract: The invention provides for an additional finger (5) engageable with a driver (7) of the rolling key (29), said finger (5) being located on an angularly movable bush (1). There is also provided a bearing ring (10) which is provided with a recess segment (17-18) into which the driver (7) extends. When said clutch actuating mechanism is disengaged with the drive motor at a standstill, the driver (7) takes up a position under spring-loading in which it bears against one edge (17) of said recess segment and sets the rolling key in its coupling position. Subsequent energisation of the drive motor will then only drive the shaft and the rolling key until the rolling key driver (7) comes to rest against the additional finger (5) of the bush (1). The rolling key is then turned back into its released position, without movement on the part of the machine. In that manner, accidents and breakdowns within the tooling area as referred to, are also avoided in the event of unauthorised actuation of the engagement/release arrangement. <IMAGE>

Abstract: A light source signal is amplitude modulated by a phase modulated sinusoid and passes through two directional couplers so that two beams are formed. The beams are transmitted to the ends of an optic-fiber coil for propagation therethrough in opposite circular directions. An optical phase modulator is present at one end of the coil so that a phase modulation of fixed frequency and amplitude is introduced to a first beam as it enters the coil and to the counterpropagating beam as it leaves the coil. The counterpropagating beams produce a signal at a photodetector which is a function of rotation rate. An electronic control unit is connected to the photodetector to generate a digital signal output as a frequency which is a measure of rotation rate. A feedback loop is completed by connecting a signal, produced by the control unit, to the amplitude modulated light source for nulling the phase shift due to rotation rate.

Abstract: The hydraulic apparatus may either be a quiet hydrostatic drive with an axial piston pump and an axial piston motor or may be a quiet pump unit formed by two axial piston pumps. In either case, the apparatus includes two rotatable cylinder blocks disposed on opposite sides of a rotationally stationary valve block and tied together by a rod which transmits forces between the two cylinder blocks so that any force tending to unseat one cylinder block from the valve block tends to seat the other cylinder block against the valve block. A resiliently yieldable sealing ring on one end portion of the rod defines a pressure chamber which receives oil at working pressure to automatically increase and decrease the axial clearance between the cylinder blocks and the valve block as the working pressure increases and decreases, respectively.
