Abstract: BLOCK CIPHER SYSTEM FOR DATA SECURITY      Abstract A device for ciphering message blocks of data bits under con-trol of a cipher key.  The cipher device performs a ciphering pro-cess for the first half of the message block of data bits from a first store by carrying out an operation in which the block of data bits is expanded by duplicating predetermined ones of the data bits of the first half of the message block.  The data bits of the ex-panded first half of said message block are combined by modulo-2 addition with an equal number of cipher key bits, selected in accor-dance with an arbitrary but fixed permutation, to produce a plurality of multi-bit segments forming the arguments for a plurality of dif-ferent non-linear 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 substitution of data bits is then subjected to a linear transformation in accor-dance with an arbitrary but fixed permutation.  The combined non-linear transformation and linear transformation results in a product block cipher for the first half of the said message block.  Then the second half of the message block from a second store is subjected to a linear transformation in accordance with the product block cipher to produce a set of bits representing a modified second half of said message block.  Finally said modified second half of said message block is loaded into the first store and the first half of the message block from the first store is loaded into the second store concurrently with the modified second half of the message block being loaded into the first store to complete a first iteration operation of the cipher device.

Abstract: ABSTRACT OF THE DISCLOSURE     A silicon ion beam plants silicon ions in a silicon compound layer such as SiO2 or Si3N4 on a silicon substrate.  Silicon ions are implanted by a silicon ion beam into the silicon compound layer and into a portion of the substrate on the side of its interface with the compound layer.  The compound layer is therefore converted into a semi-insulating layer.  The substrate is also converted into an amorphous silicon portion.          The substrate is then annealed to reconvert the silicon portion into a single crystal with the remaining portion of the substrate.  According to the method, an improved passivation property is imparted to the silicon compound layer and an exact control of the oxygen or nitrogen concentration and distribution is achieved.

Granted: 1980-03-04
Abstract: ABSTRACT   Anodised aluminium having an anodic oxide film of at least 3 microns thickness is coloured by electrolytically depositing inorganic pigment from metallic salt solutions, particularly nickel, cobalt, tin and copper salts and mixtures.  The pigment deposits are characterised by outer ends of an average size in excess of 260 .ANG. lying at a distance of 500 - 3000 .ANG. from the aluminium/aluminium oxide interface.  In a preferred method of production the anodic oxide coating is formed under conventional anodising conditions in a sulphuric acid-based electrolyte.  The anodised aluminium is then treated in phosphoric acid at a voltage of 8 - 50 volts to enlarge the pores to above 260 .ANG. in a region at the base of the pores adjacent the barrier layer.  The pigment is then deposited in the pores to the specified depth and interesting new colour shades are obtained as a result of optical interference due to the presence of the large size shallow inorganic pigment deposits.

Abstract: AN OPTICAL PULSE TRANSMISSION SYSTEM            Abstract of the Disclosure An optical ternary pulse transmission system is disclosed in which a light emitting diode is caused to generate either one of two light intensity outputs in response to the voltage pulses presented at either one of two input terminals.  The voltage pulse at each input terminal is coupled to the light emitting diode through a gain control network.  Most of the light from the light emitting diode is coupled to an optical fiber, and a first photodetector is positioned close to the light emitting diode in order to capture stray light not coupled into the optical fiber.  A second photodetector with an opaque coating is positioned such that its position and the position of the first photodetector are electrically symmetrical with respect to the light emitting diode.  The electrical signal from the second photodetector representing parasitic coupling is subtracted from the signal developed by the first photodetector in order to develop a signal dependent only on light intensity variations.  First and second comparator circuits are selectively gated by the input voltage pulses to utilize selected pulses of the light dependent signal in developing feedback voltages for the gain control networks.

Abstract: WHEEL DRESSING APPARATUS AND METHOD                 ABSTRACT OF THE DISCLOSURE           A method and apparatus for dressing adjacent faces on grinding wheel.  A single point dressing nib and a rotary dressing wheel are mounted to a common slide oriented with its slide axis parallel to a first face on the grinding wheel.  As the slide is actuated, the nib is drawn across the first face of the grinding wheel, dressing the entire face.  After the single point nib traverses the first face of the grinding wheel, the rotary dressing wheel is activated and brought into engagement with a second face on the grinding wheel, adjacent to the first face.  A cam is provided on the base which carries the slide, so that a tracing stylus will follow the shape of the cam and transmit the cam profile to the dressing nib as it traverses its path.  In the manner, therefore, an extremely accurate profile may be dressed on a first face of the grinding wheel, and a second, potentially wear-causing face may be dressed into the grinding wheel by a dressing wheel yet the rotary dressing wheel will not introduce vibrational inaccuracies into the first face.

Abstract: ABSTRACT           Apparatus for spreading and supplying laundered flat-work to an ironer in a squared condition. The apparatus is carried by a single frame. A central main drive belt and a pincher belt above the main drive belt driven by contact therewith extend along the center of the main frame for a portion of the length of the frame. These belts draw the flatwork as supplied over a semi-ovate spreader apron in advance of the ma in drive and pincher belt. Upper and lower spreader belts diverging at equal angles with respect to the main drive belt and pincher belt extend along each side of the front portion of the machine and provide a pressure nip in substantially the same vertical plane as the pressure nip between the pincher belt and main drive belt.        The upper spreader belt has a rougher surface than the lower one and spins or travels faster than the lower belt and places the laundered article under lateral tension as drawn along the appara-tus by the main drive belt and pincher belt and thereby serves to smooth the leading edge of the article. A series of parallel carry-out belts extend parallel to a main drive and pincher belt on opposite sides of these belts from the spreader belts to the discharge end of the apparatus. The speeds of the belts may be varied in accordance with the speed of the ironer. The semi-ovate spreader apron spreads and keeps the laundered article square as fed into the machine. A guard in advance of the spreader apron and at the nip between the main drive belt and pincher belt provides a restricted space into which the article is fed and prevents the pull-in of a misfed article.
