Abstract: Abstract of the Disclosure A method and apparatus are provided for improving the security of data transmissions between stations and for control-ling secured transactions from remote locations in a data-transfer system.  The method and apparatus obviate the need for transmitting user-identification information such as personal identification number (PIN) from station to station, e.g., from the station utilized by the user to enter his PIN and initiate a transaction, to the station that processes the transaction.  Also, for added security, the method and apparatus provide for encryption (encoding) and decryption (decoding) of data during a transaction using en-cryption and decryption keys produced from different (independent) PIN's. The apparatus includes at least one irreversible algorithm module, a random number generator and at least one data file (e.g., disc or magnetic tape storage).  The apparatus also includes a comparator or, alternatively, an encoding algorithm module and a matching decoding algorithm module.  In addition, a data-transfer system obviates the need for paired encryption/decryption modules on a data link while nevertheless maintaining a high level of security in the data transferred.  This facilitates remote control of data transfers between locations within the system, enables use of conventional data links, and permits convenient changes of and additions to the files of stored codes for the system without compromising the security of data transfers or of identifying codes for authorized individuals.

Abstract: WEB DRYER NOZZLE ASSEMBLY                 ABSTRACT OF THE DISCLOSURE         A web dryer has a plurality of nozzle assem-blies.  Each nozzle assembly is provided with a flat pressure plate adapted to form a gas flow zone with a moving web.  A primary nozzle of the airfoil Coanda type is disposed at the upstream end of the pressure plate and continuously directs gas downstream along the face of the plate.  A single secondary nozzle of the impingement type is disposed at the generally right angled downstream terminus of the pressure plate to continuously direct gas initially substantially perpendicularly to the web and to gas flowing downstream along the gas flow zone.  The posi-tion of the secondary nozzle assures that the full width of the pressure plate is utilized.  The gas flow volume through the secondary nozzle is less than half that of the primary nozzle.  Furthermore, the gas flowing from the secondary or impingement nozzle turns to take the down-stream direction of the main gas flow and also serves to cause compression of the main gas flow against the web downstream of the pressure plate and nozzle assembly ter-minus.  An increase in the rate of heat transfer to the web is thus produced in the free area between adjacent nozzle assemblies.  The compressive restriction of the main gas also tends to increase its unidirectional air flow velocity, which in turn isolates the web from the effects of mis-cellaneous gas flow currents within the enclosed dryer housing.  The overall result is a slight back pressure or increase in static pressure in the gas flow zone which assists in keeping the moving web spaced from the pressure plate, but the back pressure is insufficient to reverse the direction of main gas flow.

Abstract: ABSTRACT:            A thermal energy storage medium comprising a hydrophilic polysaccharide supporting an inorganic salt that is capable of transforming from one phase to a less hydrated phase absorbing latent heat, and releasing this latent heat upon the reverse transformation.  The polysaccharide, preferably Xanthan Gum, may be incorporated in concentrations of 0.05% to 3% together with a nucleating agent in order to form a material that transforms when cooled back to the transformation temperature, or in greater concentrations of 1% to 5% without a nucleating agent to form a material that may be cooled below the transformation temperature without transformation taking place, and stored at ambient temperature whilst still storing the latent heat until activated.     The medium is gelled in the less hydrated phase and in some embodiments the gel is pseudoplastic thus enabling it to be poured into chambers of an energy storage device, and then regain its original viscosity at rest.

Abstract: PHB 32971                -25-                  20.1.1984 ABSTRACT: APPARATUS FOR DISTINGUISHING BETWEEN SPEECH AND CERTAIN OTHER SIGNALS.      Apparatus for distinguishing between speech and, for example, data and noise signals, for example for use in a non-speech squelch circuit in a broadcast receiver, utilises the fact that an autocorrelogram of a speech signal exhibits peaks which wander backwards and forwards along the delay axis, this not being the case for auto-correlograms of most other signals. Autocorrelograms of an input signal applied to an input terminal (1) and hard-limited by means of a comparator (5) are formed under the control of a computer (14) by means of a shift register (3), a multiplexer (10) an inverting EXOR-gate (7), an up/down counter (19) and a memory (41). For each clock pulse fed to the clock input (30) of the shift register the output (11) of the multiplexer, and hence one input of the EXOR-gate, is switched to each of a succes-sion of taps (8) on the shift register. Thus the signal on the first tap (6) of the register is multiplied in succession by the signals on the other taps (8) and the results are used to increment or decrement corresponding quantities in the memory (41) by means of the up/down counter (19). Autocorrelograms relating to successive periods of time are formed in this way and the computer determines the positions of the peaks (if any) in each and by comparison of these positions determines whether they are stationary or wandering.            (Fig. 2).
