Abstract: An arrangement for differential pulse code modulation coding comprises a controllable quantizer and a quantizer controller and is dependent on picture signal values. The quantizer controller contains a plurality of series-connected registers which store adjacent picture element signal values. A comparison device provides a differential formation between all picture signal values and a control is provided to which all results of the difference formations are supplied and which controls a multiplexer such that only the respectively highest and lowest picture signal values, the extrema, are through-connected for further processing. A subtractor, wherein the difference between the last picture element signal value and the extrema, as well as between the extrema themselves are identified is also provided. A difference selection control through-connects the maximum difference to a threshold logic which controls the quantizer in accordance with the amount of the maximum difference.

Abstract: 1. A process for eliminating gaseous organic pollutants, which can also be present in traces, from waste gases by biological oxidation using bacteria, wherein the gas stream containing one or more organic pollutants is led through one or more biologically active layers in fluidized bed reactors and, for wetting the bacterial cultures fixed on the surface of the carrier, a liquid stream is circulated in a co-current or counter-current during operation, characterised in that the biologically active layers are produced by bringing a porous, pollutant-adsorbing, carrier material, which has a high internal surface area and is selected from the group comprising activated carbon, zeolite and silica gel, into contact with a pollutant-specific suspension of a bacterial monoculture and/or mixed culture.

Abstract: An apparatus for transporting receptacles or the like in a filling and/or sealing machine has one or more endless conveyors or a turntable and several sets of locating members for individual receptacles or groups of receptacles. The selected locating member are separably coupled to the turntable or to discrete supporting plates on the conveyor or conveyors so that their sockets can accept individual receptacles for transport past one or more filling and/or other stations. If the machine is to treat differently dimensioned and/or configurated receptacles, the previously used locating members are replaced with a different set of locating members having sockets which can properly receive the newly selected receptacles for transport past one or more stations. Each locating member can be in a mere linear or in full surface-to-surface contact with the corresponding receptacle or receptacles. The selected locating members can be affixed to the upper side or underside of the turntable or to the upper sides or undersides of discrete supporting plates.

Abstract: Solid objects made of plastic or with a top layer of plastic or lacquer are printed by the transfer printing process by laying a flat dyestuff carrier on the surface of the solid object to be printed and heating the dyestuff carrier to the sublimation temperature of the dyestuff. In accordance with the invention during the course of the dyestuff transfer between the dyestuff carrier and the surface requiring printing a layer of material of a non-adhesive nature or one which is easily removed is inserted, this material being substantially permeable to the transfer of the dyestuff, so that impressions from the dyestuff carrier on to the surface are avoided. Preferably, a plastic slab coated with a polyolefin film is printed, where the film is left on the surface after printing, as a protective layer.

Abstract: The clamping circuit clamps a threshold of an ADC to a signal level just below the black level of a television signal. 
<??>During the blanking period, a negative-going peak is superimposed on the input signal to produce the waveform 76. Each time this crosses the 0000,0001 threshold of the ADC, the polarity of the output of a comparator changes (see the middle waveform). The comparator compares the ADC output and a reference value. 
<??>The input signal is biased according to the integral of the comparator output. When signal levels are stable, the comparator output is symmetrical, its integral is zero and no change occurs in the biassing. 
<??>If signal levels drift, the negative going peak crosses the threshold for the second time relatively sooner or later. The comparator output becomes assymmetric and has a non-zero integral. Consequently, the biassing level changes to compensate for the drift.

Abstract: Entrance telephone installation intended to be connected to a public telephone network, said installation including a number discriminator with line access and dialling facilities, addressable from an entrance telephone set for connection of a circuit to specific reply sets, said reply sets being arranged to facilitate signalling via the circuit switched through in the telephone network to accomplish door lock opening. According to the invention, a specific ID-signal is transmitted to the telephone network during a first predetermined time period after completed switching operation to a specific reply set, with simultaneous monitoring of the telephone network with regard to digits entered from called reply set transferred via the telephone network as a pulsed signal, multi frequency signal or optical signal, absence of such digit entered from the reply set during said first time period resulting in disconnection of the connection. Detection of one or a number of digits entered from the reply set during said first time period being interpretated as specific commands, which are transformed into specific actions, for example establishment of video and/or speech communication with the entrance set, blocking action preventing repeated calls during a predetermined time period, immediate disconnection, alarm transmission from the entrance set or any other predetermined function. The first time period is followed by a second time period, provided that a predetermined digit is entered during the first time period, whereunder video and/or speech communication can take place between the reply set and the entrance set. Digits entered from the reply set during said second time period are detected and interpretated as specific commands, which with regard to resulting function for one or a number of individual signals result in different resulting functions in relation to corresponding signal(s) during the first time period.

Abstract: Alkali hydroxide, chlorine and hydrogen are produced from an aqueous alkali chloride solution by membrane electrolysis. A high-NaCl solid salt, which contains impurities, is dissolved in water in a salt dissolver. Precipitating chemicals are added to the salt solution to precipitate the impurities. The resulting mixture is fed to a thickener, from which precipitates and clarified raw brine are separately withdrawn. The clarified raw brine from the thickener is divided at a ratio between 2:1 and 20:1 into first and second partial streams. The larger first partial stream is mixed with the salt solution and the precipitating chemicals before entering the thickener and the resulting mixture is fed to the thickener. The second partial stream of the clarified raw brine is fed through a fine purifier to the electrolytic cell. Spent brine from the electrolytic cell is fed to the salt dissolver.
