Abstract: Values, such as a set of coefficients in a transform-based video coder are to be transmitted sequentially in any one of a number of possible preset orders. The order to be selected is the one that results in the largest number of consecutive zeros (or low values) at the end of the sequence. Values are supplied (in an arbitrary sequence) with addresses, in parallel to a bank of assessment sections - one for each preset order - each of which translates the addresses into addresses representing a position in the respective order and records the highest for which the associated value is non-zero. The outputs of the sections are than compared to identify the lowest, and hence the optimum order of transmission.

Abstract: A method of making a catalyst composition comprising an activated alumina coating stabilized against thermal degradation includes applying a coating of alumina having one or more platinum group metal catalytic components dispersed thereon onto a carrier substrate and calcining the coating. The calcined coating is then impregnated with a solution of a thermal stabilizer-precursor and calcined again to provide a thermal stabilizer in the alumina. Bulk ceria, optionally an aluminum-stabilized bulk ceria, may also be added to the composition, preferably at specified minimum levels, including a high purity bulk ceria on which one or more non-rhodium platinum group metal catalytic components, e.g., platinum, optionally, are dispersed. A separate aspect of the invention provides for a method of making a catalyst composition including dispersing one or more platinum group metal catalytic components on an activated alumina and calcining the combined alumina and platinum group metal catalytic components. The steps are carried out under limited acidification conditions whereby at least minimum dispersions of the platinum group metal catalytic components are attained. The invention also provides for catalyst compositions resulting from either or both the foregoing methods.

Abstract: There is described a multilayered, flexible marking tape comprising an auxiliary support and a contact-adhesive layer. Between the auxiliary support and the contact-adhesive layer there is situated a binder-containing cover layer which is more adherent to the contact-adhesive layer than to the auxiliary support. The contact-adhesive layer has been coloured with a colorant, in particular a pigment. If fluorescent pigments are incorporated into the contact-adhesive layer, the marking tape becomes highly suitable for marking or highlighting passages in written text. A suitable choice of contact adhesive permits later easy removal without impairment of the marked sheet.

Abstract: An integrated processor is fabricated on a single monolithic circuit and employs circuitry to accommodate data-intensive, view-intensive and voice-intensive requirements of modern-day PIDs. The integrated processor includes a CPU core, a memory controller, and a variety of peripheral devices to achieve versatility and high performance functionality. The integrated processor consumes less power by provision of a clock control unit including a plurality of phase-locked loops for generating clock signals of differing frequencies to appropriately clock the various subsystems of the integrated processor. The clock signals provided to the various subsystems by the clock control unit are derived from a single crystal oscillator input signal. A power management unit is incorporated within the integrated processor to control the frequency and/or application of certain clock signals to the various subsystems, as well as to control other power management related functions. The pin-count of the integrated processor is finally minimized by allowing the selective multiplexing of certain external pins depending upon the desired functionality of the integrated processor. <IMAGE>

Abstract: A thermally activated, dry refractory composition and method for the high temperature, dry application of a new refractory lining or the repair of an existing refractory lining on an interior surface of a furnace and the like is disclosed. The composition includes a refractory aggregate and a hydrated material containing chemically bound water of hydration, such as a metasilicate hydrate, which give the composition a self-flowable property, and may include other binders, homogenizers and flowability enhancing agents, such as calcium carbonate and phosphate glass. The refractory composition is placed in a dry state into a hot furnace at a temperature of at least about 500  DEG C, in communication with the surface to be coated. The water of hydration is released at the high temperature causing the composition to become a self-flowable aqueous slurry which coats-out on the surface. Continued exposure to the high temperature causes vaporization of the water with consequent drying and setting of the composition leaving a refractory lining in place on the surface.
