Abstract: A programmable phase-locked loop frequency synthesizer having a feedback path that includes a tuned discriminator circuit (18) is frequency modulated by coupling a portion of the modulating signal into the feedback path to effect modulation at rates which exceed the bandwidth of the phase-locked loop and by utilizing a portion of the modulating signal to frequency modulate the phase-locked loop reference signal to effect modulation at rates within the bandwidth of the phase-locked loop. A digitally-controlled phase shifter (40) that forms a portion of the tuned discriminator circuit (18) in effect divides the phase-locked loop tuning range into a series of relatively narrow contiguous frequency bands. Data, representing deviations in the discriminator characteristics for each of these frequency bands, are stored in an erasable programmable read only memory (70). As the phase-locked loop is tuned to a particular frequency, a microprocessor (14) determines the associated frequency band, accesses the stored data appropriate to that frequency band and establishes the proper setting of the digitally-controlled phase shifter (40). The accessed data is coupled to a multiplying digital-to-analog convertor (64) to automatically adjust the level of the modulating signal so that the system exhibits relatively constant modulation characteristics for each frequency band within the tuning range of the phase-locked loop.

Abstract: In welding-current sources equipped with a plurality of parallel- connected transistors for regulating the welding current, the respective bases of which are connected in parallel with one another and are controlled by a common control device, and in each of which a resistor serving for balancing is inserted in the emitter circuit, there is the problem of keeping this welding-current source ready for operation even in the event of a collector/base breakdown, so that the welding operation does not have to be interrupted. This is guaranteed by inserting a fuse into the feed line branching off from the supply line to the base of the parallel-connected transistors, the rating of this fuse being such that, when a predetermined nominal current in the particular base feed line is exceeded, it interrupts this. <IMAGE>

Abstract: So-called incineration units for the recovery of silver from films are known. These pollute the environment and require expensive filter installations. The present process and apparatus for carrying out the process avoid these disadvantages. It requires only small funding and avoids expensive filter installations. The film is comminuted in a mill and then passes into stripping tanks with an enzyme-containing solution. After completion of the stripping step, the solution including film passes into a washing drum, in which the film is washed out. The solution separated from the film flows into a receiver tank underneath the washing drum and from there into intermediate storage tanks with stirrers. The solution then passes into a centrifuge, and the deposited solid is taken from there to a drying cabinet. After the end of drying, the material is ignited in a special furnace and then, with addition of a melting agent, melted in a melting furnace and subsequently cast to give ingots. The process takes place in the items of apparatus in the following order: mill, stripping tank, washing drum, intermediate storage tank, centrifuge, drying cabinet, igniting furnace, melting furnace. A particularly advantageous factor of the plant with regard to the environment is that the stripping tanks are heated by means of the stack exit air, the entire length of the furnace tube being wound with a water-filled copper line which leads to the stripping tanks and back again to the furnace tube, with an interposed circulation pump.

Abstract: The invention provides a method of digital encoding of speech signals which has advantages over adaptive coding methods in that it facilitates processing of the encoded signals for example by pause removal, speech rate control, storing and forwarding etc, but which does not require as high a bit rate for a given speech quality as pulse code modulation. 
<??>In the method of the invention the speech signals are digitised during successive time intervals to produce pulse code modulated samples and these samples are standardised for each interval by subtracting from each the minimum sample value and dividing each difference by a scale factor proportional to the sample range. The standardised samples, together with values for the minimum sample value and the scale factor, are coded into code words, each representing one time interval. An example of a code word is shown in Fig. 7. 
<??>During pauses, only a single code word is generated, which, of course, represents the background noise level, and the code word includes the coded number of time intervals of silence representing the length of the pause. 
<??>A mu-law encoder/decoder may be used for digitising the speech signals. 
<??>In the examples given a 41 millisecond time interval is proposed, divided into 246 sampling intervals, each represented by 4-bit code, the sample codes and other information, including check digits, being packed into a code word onsisting of a 128 8-bit bytes.
