Filed: 1997-02-14
Abstract: Information symbols spread using orthogonal or bi-orthogonal codewords are assigned a unique scramble mask that is taken from a set of scramble masks having selected correlation properties. The set of scramble masks is selected such that the correlation between the modulo-2 sum of two scramble masks with any codeword is a constant magnitude, independent of the codeword and the individual masks being compared. In one embodiment, when any two masks are summed using modulo-2 arithmetic, the Walsh transformation of that sum results in a maximally flat Walsh spectrum. For cellular radio telephone systems using subtractive CDMA demodulation techniques, a two-tier ciphering system ensures security at the cellular system level by using a pseudorandomly generated code key to select one of the scramble masks common to all of the mobile stations in a particular cell. Also, privacy at the individual mobile subscriber level is ensured by using a pseudorandomly generated ciphering key to encipher individual information signals before the scrambling operation.

Title: Pulverulent plastic compositions including bituminous or resinous binding agents
IPC: C08L95/00
Filed: 1943-01-21
Abstract: Pulverulent plastic compositions are prepared by dispersing in air, &c. particles of a binder, e.g. resin or synthetic resin, asphalt, coal tar, or pitch at a temperature at which it is liquid, and causing cooler solid particles to collide with and adhere to the surfaces of the binder particles, the product being thus nonadhesive, but convertible by heat or solvent action so that the binder wets and covers the solid particles.  The copuscles thus formed may be kept apart by a liquid immisible with the binder, e.g. by water which may be later taken up by adding Portland cement.  The corpuscles may be agglomerated, and used for moulding, building, roads, joints, or may be applied to felt, fabrics, cardboard, or paper, &c.  The solid particles, 80 per cent of which have diameters not greater than 74 microns, comprise, e.g. powdered slate, carbon, calcium carbonate, talcum, kaolin, zinc oxide, pigments, ground scrap rubber, lignin, cork flour, wood flour, asbestos fines or cotton, wool, cellulose, or synthetic fibres.
