Abstract: Abstract of the Disclosure A CATV channel assignment system and method for arranging CATV channels in a tiered fashion facilitates selective viewer access to predetermined groups of CATV channels.  A "logical" channel number is generated upon channel selection and is provided to a microcomputer which, in turn, generates a corresponding look-up PROM address. The logical channel number is converted by means of the thus generated address to a "physical" channel number in the PROM.  The physical channel number represents a standard CATV channel and is provided to the microcomputer for synthesizing the correct tuning frequency via a phase lock loop and conventional tuning circuitry.  For a two cable system automatic cable switching is provided to permit channels on either cable to be included within the same group of selected channels.  The present invention facilitates the "tiering" of CATV channels into predetermined groups of channels, wherein each group has a viewer access authorization level associated therewith, and in which all channels in a group may be assigned logically related channel numbers, e.g., consecutively arranged channel numbers, while the corresponding standard channel numbers may be widely disparate and unrelated in a given group.  This arrangement facilitates viewer channel selection by organizing subscribed-to channels into easily remembered numerical sequences and simplifies selective accessing of CATV channels by arranging these channels into two or more tiers where the channel numbers in each tier are logically related and not randomly assigned.

Abstract: ABSTRACT        A panel having a cellular core and an acoustically semi-transparent facing is provided. The core, which may be a honeycomb, has cells opening to a face of the core.  The facing is bonded to the face of the core such that pillow-like portions of the facing extend into the open cells of the core to provide a mechanical interlock between the facing and the core and to improve the absorption of acoustic energy directed upon the panel.  The panel may include a layer bonded to the core opposite the facing for reducing the transmission of acoustic energy through the panel or for increasing its strength and rigidity.   Preferably,  the facing is non-homogeneous such that the density of the pillow-like portions is less than the portions of the facing adjacent the structure of the coxes  The panel may be formed by heating and compressing an uncured fibrous element of relatively uniform thickness and density against a cellular core.  A heated platen may be used to produce a relatively flat, hardened outer surface of the panel.

Abstract: "FINNED HEAT EXCHANGER TUBES AND METHOD AND APPARATUS FOR MAKING SAME"                   ABSTRACT           Improved method and apparatus for making finned tubing from difficult to work materials such as titanium and stainless steel uses spaced sets of finning discs on a plurality of arbors to form a tube against a mandrel having different diameters under each set of discs.  By forming the tube fin tips to their final O.D. in a first disc set and by deepening their roots to bring the fins to their final height in a second disc set, tubes with higher fin counts and/or higher fin heights can be achieved than were formerly possible.  The process of separately cold working the tips and roots also permits tubes to be made which are dimensionally identical to prior art tubes but with higher quality and productivity since tube stresses are greatly reduced.  An improved titanium tube is also dis-closed which has at least 26 fins per inch, a fin height of at least 0.034" and an outside to inside surface area ratio of at least 3Ø

Abstract: ABSTRACT ARCHITECTURE FOR SMALL INSTRUCTION CACHES      A branch target table (10) is used as an instruction memory which is referenced by the addresses of instructions which are targets of branches.  The branch target table consists of a target address table (12), a next fetch address table (14), a valid entries table (16) and an instruction table (18).  whenever a branch is taken, some of the bits in the untranslated part of the address of the target instruction , i.e. the instruction being branched to, are used to address a line of the branch target table (10). In parallel with address translation, all entries of the branch target table line are accessed, and the translated address is compared to the target address table (12) entry on that line.  If the target address table entry matches the target address, the instruction prefetch unit (32) fetches the instruction addressed by the next fetch address table (14) entry for the given line and the line of instructions associated with the branch address table entry is read into an instruction queue (38) having a length set by the valid entry table (16) entry which indicates how many of these instructions are valid.  Otherwise, the instruction prefetch unit (32) fetches the target and subsequent instructions as it would if there were no branch target table, and the target address table entry is set to the real address of the target instruction.  The next fetch address table (14) is updated so that it always contains the address of the instruction which follows the last valid instruction in the line, and the valid entries table (16) is updated so that it always counts the number of valid instructions in the line.
