Abstract: Title of the Invention A PROGRAMMABLE CRYPTIC DEVICE FOR ENCIPHERING AND DECIPHERING DATA          Abstract of the Disclosure An encrypter for encoding and decoding data, wherein clear text data to be encoded is logically combined with a portion of a non-linear pseudo-random bit sequence signal to provide a partially encoded signal.  The bit se-quence of the non-linear pseudo-random signal is chosen in accordance with a user selected key.  A shuffle register receives the partially encoded signal and interchanges the positions of the bits making up the partially encoded sig-nal in accordance with a user selected key to provide the fully encoded signal.  The fully encoded signal may then be recorded, for example, on the magnetic stripe of a credit card.      Means are provided for decoding the above de-scribed encoded signal using the same portion of the non-linear pseudo-random bit sequence that was used for en-coding.

Abstract: ABSTRACT OF THE DISCLOSURE         A process of general applicability in the micro biological field wherein a culture is subjected to periods of availability and non-availability of an essential energy source such as a carbon source, i.e. the energy source is supplied in pulses.  The efficiency of the culture in con-verting substrate carbon to cellular carbon varies depending upon the relative duration of the periods of availability and non-availability of the energy source.  Thus depending upon the relative duration chosen the process can be applied differently, i.e. when the efficiency is high the process is suitable for single cell protein production whilst when it is low it is suitable for wastewater treatment.
