Abstract: A method of, and apparatus for, enciphering and deciphering audio information which is subdivided into partial blocks along a time axis, the partial blocks being mutually interchangeable according to key information. The incoming analog audio signals are subdivided into a number of frequency bands, each of which is assigned to an information channel. The analog audio signals of each information channel are converted into digital signals which are subdivided into main blocks along the time axis. The main blocks of equal time of each information channel are subdivided into sub-sections of the same magnitude with respect to time and which are interchanged, in accordance with the key information with sub-sections of the same main block or with sub-sections of a time-equal (i.e. isochronal) main block of another information channel. After the interchange in each information channel, the digital signals are converted into analog signals and the interchanged sub-sections are group together into new main blocks, in order to render possible a further processing of the time-equal or isochronal new main blocks of each information channel.

Abstract: A banking system is provided which is comprised of a central computer, a customer accounts main memory, and plural remote transaction terminals in communication with the central computer. Each remote terminal includes a cash dispensing apparatus, a personal identification number (PIN) signal generator, a random number (RN) signal generator, a security device and a cash dispenser. The communication paths from the RN and PIN signal generators to the security device are wholly contained within the remote terminal and inaccessible to would-be thieves. The remote terminals also include data entry devices activated by a customer to provide a PIN number, a PIN OFFSET number bearing a predetermined relationship to both the PIN number and a customer information file (CIF) signal stored in main memory, and other banking information. In response to a customer-initiated operation, a remote terminal supplies bank transaction and customer identification information to the central computer. Upon receiving information from a remote terminal, the central computer searches the customer's record in main memory for a CIF number associated with the customer's account. The central computer thereafter forms a composite signal from the RN, CIF and PIN OFFSET signals which is applied to the security device of the remote terminal. The RN signal serves to conceal both the CIF and PIN OFFSET signals from an attempted interception during transmission from the central computer to the remote terminal. The security device includes a comparator for generating a DISPENSE signal when the PIN and RN signals bear a predetermined relationship to the composite signal. The cash dispenser includes a cash storage portion and a dispensing mechanism for issuing one or more cash units in response to a DISPENSE signal.

Abstract: A channel identification apparatus for a TV receiver includes a memory 37 for storing binary signals representing boundary voltages having magnitudes corresponding to magnitudes of the tuning voltage between tuning voltage ranges for respective adjacent channels. As the memory locations at 37 are addressed, the boundary voltages are compared 49, 55 to a tuning voltages. Control apparatus 41 causes the memory location associated with the next boundary voltage to be addressed and causes channel number apparatus 43, 45 to generate binary signals representing the next channel number when the magnitude of a predetermined one of the boundary voltage associated with an addressed one of the memory locations and the tuning voltage exceeds the magnitude of the other one. Display apparatus 59 such as LED's displays the channel number represented by the binary signals generated by the channel number apparatus. Because the boundary voltages are utilized, the channel identification apparatus described is particularly suited for use in a signal seeking or manual tuning system. <IMAGE>

The group (7) of tubes is passed through at least one nozzle plate (18) or nozzle basin (22) so that nozzle openings (16, 20, 23) surrounding the tubes are formed between the openings in the nozzle plates and the tubes. In the heat exchanger the liquid to be vaporized is passed to the mantle side into the upper part of the heat exchanger or into each nozzle basin of the heat exchanger separately and is guided so as to flow downwards on the outer face of the group (7) of tubes as a liquid film. The vapor developed from the liquid film is, by means of vapor flow passages formed into the group (7) of tubes, passed from the lower part of the heat exchanger further into its object of use or from each component unit (1, 2, 3) of the heat exchanger further into its object of use.

Abstract: A telephone line circuit including a high voltage amplifier feeds the tip and ring lines at its output. This amplifier is fed by a programmable voltage source which includes a d.c./d.c. converter and means to control the amplitude and polarity of this voltage. All the required electrical signals including d.c. feeding, speech, unsymmetrical ringing and metering pulses are provided through the high voltage amplifier. No high voltage AC switches (relay contacts) are required since the ring signal is provided through the same device (output amplifier) as the speech and d.c. signals. Means are included for minimizing the internal power dissipation by controlling the amplitude of the d.c./d.c. converter voltage. Thus d.c. offset control is achieved by slaving the d.c./d.c. converter voltage to the amplifier output voltage. Three functional blocks form the line interface circuit according to the invention, these being a high voltage circuit including the aforementioned amplifier, a programmable signal generator which includes the d.c./d.c. converter and electronic solid state switching under control of a line feed and supervision circuit which constitutes the third block.
