Abstract: Signal generating apparatus comprises a phase-­locked loop (PLL) (1,3,5,7,9) utilizing a voltage-­controlled oscillator (VCO) (1) and a frequency-locked loop (FLL) (9,1,13) to generate an output signal, the frequency of which jumps from one value to another in a selectable sequence; the signal generator further includes a delay line discriminator (13) to provide an error signal to compensate for FM noise in the VCO (1). The frequency-locked loop is implemented by utilizing the FM error signal from the delay line discriminator (13) to stabilize the center frequency of the VCO (1). The inherent wide bandwidth of the FLL provides a fast settling time when the loop is switched to a new frequency. In a learn mode, the gain parameters of the loop are determined and stored for each of a plurality of frequencies. The gain parameters and a corresponding pretune signal for each selected frequencies are then applied to the FLL in a selectable sequence to provide a fast-switching signal generator.

Abstract: An analog interface system (10) interfaces with a digital signal processor. The system receives analog signals, digitizes those signals (14) and transmits them to the signal processor upon completion of the conversion. The system directs transmission of digital data (IDX) from the signal processor to the system, and converts it (24) to analog as the output of the system. The A-to-D and D-toA- conversion rates are selected by the system control, responsive to data received from the signal processor.

Abstract: A process for the production of agglomerates of aluminium hydroxide having a large grain size from an alkaline aluminate solution is presented. This process comprises the steps of dividing the alkaline aluminate solution into two part streams, one part stream being passed into the agglomeration section and the other being passed into the growth section with final stirring. A fine seeder, consisting of a deactivated ground seeder, is added to the agglomeration section and the flow is cooled during final stirring, in order to agglomerate the particles. The agglomerated particles are separated off, a partially stirred solution remaining which is introduced into the flow fed into the growth section. The growth part stream is cooled for precipitation of product hydroxide. This is separated off and the thin solution is recycled. A part of the product is ground to the grain size of the fine seeder and added to the partially stirred solution, whereby the ground seeder is deactivated and a new precipitate is formed. The ground seeder and the new precipitate are added to the agglomeration flow, so that the final stirring cycle is closed. Since the starting seeder for the process is formed by mechanical means by grinding a part of the product, the nucleation step in the final stirrers is dispensed with. Hydroxide classification is therefore not required. The production of solid coarse Al(OH)3 particles by this process at high caustic productivity and a single pass of the material reduces the dimensions of the final stirrer and thus saves capital investments and power consumption.

Abstract: For illuminating an object in a transmission electron microscope, two condenser lenses (13a, 13b) are employed in such a way that they from an image of the electron source with different reduction. This crossover (11c) is imaged in the TEM operation by a third condenser lens (14) in the focal plane (17b) of a KOE front prelens (17v), as a result of which the size of the illumination aperture can be set. Before the KOE lens (17), the electron beam is cut by two diaphragms (35, 39; 35, 45; 95, 99) arranged in different planes and by at least one deflection system (16) in such a way that the size of the illumination field on the object (18) is only slightly larger than the area enlarged by the electron microscope. The size of the illumination field and illumination aperture can be set independently of one another.

Abstract: A sawtooth voltage is applied to an integrated optic phase modulator (12) by means of a high impedance variable current source (14) in response to a charge rate control signal (22).The phase modulator's capacitance accumulates the charge which manifests a voltage comprising the sawtooth signal. The sawtooth signal is also provided to a comparator (16) which in turn provides a discharge signal (28) upon detecting the sawtooth voltage as being greater than a selected reference signal magnitude (26). The discharge signal is provided to a means (18) for discharging the accumulated charge from the capacitance of the integrated optic phase modulator. A compensating resistor (32) may be connected between the current source and the phase modulator to automatically correct for sawtooth overshoot. Various data extraction techniques are disclosed, without limiting the invention since others may be used, including counting sawtooth resets, among others, and using a current splitter to store charge separately from the serrodyne modulation circuit and relating separately stored charge to angle or rate.

Abstract: In an arc furnace, it is intended to prevent contact of the electrodes with the cover in the region of the electrode ducts during tipping of the furnace vessel, in a manner which is simple to manufacture and to carry out. The gantry (11) is arranged such that it is resistant to tipping and can move in the horizontal direction with an axis of rotation (13) at a distance from a tipping plane. A tipping movement of the furnace vessel (5) can be converted into a rotational movement of the gantry (11) via a coupling device (37, 39, 41) between the furnace vessel (5) and the gantry (11) such that, during tipping of the furnace vessel (5), the sections of the electrodes (23, 25 and 27) engaging in the electrode ducts (31) are driven with the movement in the horizontal direction, essentially corresponding to the horizontal displacement of the electrode ducts (31). Coupling devices which act both mechanically as well as electrically can easily be used. For example, even arc furnaces which are already installed can be reequipped in a simple manner with a coupling device according to the invention. <IMAGE>

Abstract: A fast packet and frequency switch, with inputs and outputs connected to optical fibres, each of them allowing the transit of a certain number of different-wavelength optical carriers, modulated by serial information flows organized into packets. Said packets are phase-realigned and their label is converted upon the control of external processors designed to set-up and break connections. 
     Then a frequency conversion of the optical carriers allotted to packets is carried out and the packets are recombined into a unique fibre by a passive recombination network in order to be stored into an optical loop memory, which is an optical fibre delay line. 
     Each optical packet flow is extracted at suitable times, is frequency- converted and among the various frequencies obtained there are selected only those to be sent to corresponding output fibres outgoing from the switch, after having been recombined with those of the other converted flows.
