Abstract: PRODUCT BLOCK CIPHER SYSTEM FOR DATA SECURITY            Abstract A device for ciphering a block of data bits under control of a cipher key.  The cipher device performs a ciphering process for the block of data by carrying out an operation in which the block of data bits is first expanded by duplicating predetermined ones of the data bits.  The data bits of the expanded block are combined by modulo-2 addition with an equal number of cipher key bits, selected in accordance with an arbitrary but fixed permutation, to produce a plurality of multi-bit segments forming the arguments for a plurality of different nonlinear substitution function boxes.  The substitution boxes perform a plurality of nonlinear transformation functions to produce a substitution set of bits which are equal in number to the number of data bits in the first half of the message block.  The sub-stitution set of bits is then subjected to a linear transformation in accordance with an arbitrary but fixed permutation.  The combined non-linear transformation and linear formation results in a product block cipher of the block of data.

Abstract: ABSTRACT     A dielectric sheet one side of which is coated with a film of thermoplastic material is heated to the softening point of thermoplastic material prior to exposure to object-modulated X-rays in an ionography imaging chamber whose interelectrode gap is fill-ed with a high Z gas.  The thus obtained relief image on the film is cooled prior to transferring the sheet into a second gas-filled gap of the imaging chamber wherein the sheet is in register with the light source and optical elements of a device which renders the relief image visible in accordance with the schlieren optical effect.  The relief image can be projected onto a web of photosen-sitive material to produce a permanent record of the relief image.          During movement back into the interelectrode gap, the sheet is caused to pass along a corona discharge device which neutralizes its charge, and the sheet is heated to the softening point of the thermoplastic material to erase the preceding relief image and to render the sheet ready for exposure to X-rays which are modulated by another object.

The flip-flop circuit is com-prised of an input logic gate, an integrator and a logic latch circuit.  In operation, the input logic gate changes state upon the coincidence of input signals,which change in state causes the integrator to change output level at a controlled rate.  The latch circuit is sensitive to the output level of the integrator and changes state only when the integrator's output level reaches or exceeds preselected thresholds.

Abstract: ABSTRACT OF THE DISCLOSURE            A process for recovering a viscous, combustible material, for example tar from a tar sand or oil and bitumin from heavy oil, from a sub-surface deposit of the material.          The process comprises forming a substantially vertical main bore into the deposit and igniting the deposit adjacent the base of the bore.  Such ignition may be carried out by any means, for example by burning a fuel, by an explosion or by a laser beam.  Generally the ignition is assisted until such time as the material in the deposit is ignited.  A supply of air is arranged to the ignition site so that a self-sus-taining combustion takes place in the bore once the ignition is properly established.  This combustion is supported by a natural draft generated by the combustion.  The gaseous products of the combustion can leave the bore and the heat of the combustion and of the gaseous products of combustion as they leave the bore liquefy the material in the deposit.          This heat can also be used to develop steam from water supplied to a vessel in the bore, which steam also assists in liquefying the material.  The liquefied material is extracted from the bore.  The process avoids the high pressure requirements of the prior art processes and, in particular, does not need high fluid pressure to drive the liquefied products from one bore to another bore.
