Abstract: A combined digital-to-analog converter and latch memory circuit (10) includes an R-2R resistive ladder network (12) and a current-controlled latch memory 18. The R-2R resistive ladder network has plural input nodes (100 and 102) and an analog signal output (104). Each of the input nodes corresponds to a different bit of a digital word that is to be converted to an analog signal. The current-­controlled latch memory includes plural subcircuits (14 and 16). Each of the latch subcircuits uses an amount of current to store the logic state of the bit of the digital word and to derive directly the node of the R-2R resistive ladder network. This configuration promotes the efficient use of space, power, and circuit elements.

Abstract: A translator is organized to include at least a pair of content addressable memories (CAMs) (12a, 12b), each for storing a different portion of the total number of bits of each of the words to be translated. The outputs from each CAM are logically combined within a multiple input random access memory (RAM) (14). Both CAMs are interrogated simultaneously and deliver the results of comparing the word portions of an input word and the CAM contents to the RAM in substantially less time than required for a single CAM memory. The results are logically combined within the RAM which, in response to a match condition, delivers the results of the translation as an output.

Abstract: There is disclosed herein a system for rapid processing of the data records of many moving and nonmoving objects on a playfield only part of which is displayed and for determining collisions between objects. A search pipeline using a synchrounous state machine searching a linked list of the records organized by approximate position on the playfield implements the search function. A lookahead cycle in the state machine is provided to continue searching for the next object which is to be visible while the graphic data from a previously found object is being loaded into a line buffer. Slips point to the first objects on the list for the current scan line speed up the search process. The collision detect process is speeded up by only checking the nearest neighbors on the playfield in the path of movement and by organizing all the moving and nonmoving objects on the playfield in a two dimensional array mapped to the approximate position of display of the object on the playfield.

Abstract: Non-intermeshing two-wing rotors 81/82 for use in high intensity mixing machines of the batch type provide new sequences and new characteristics of dynamic interactions for achieving advantageously increased mixing effectiveness, improved performance and productivity for such machines. These new rotors are adapted for driving at unequal speed (unsynchronized rotation) or at equal speed (synchronized rotation), and thus they are adapted for retrofitting into existing mixing machines. The optimum results are achieved by turning the two rotors at synchronous speed with a phase angle relationship of about 180° between rotors as shown by various well-known performance criteria. These criteria are plotted, and rating results are tabulated as compared with 0°, 90° and 135° phase angle relationships. By virtue of driving the rotors at synchronous speed with the phase angle relationship of about 180°, a powerful squeeze-flow mixing action and advantageous pull-down effect on the materials being mixed is produced twice during each cycle of rotation. the mixing chamber of the machine can be loaded with materials to be mixed at a higher "fill factor" than conventionally used. The ability to use a higher fill factor plus the marked decrease in rejected or unsatisfactory mixed batches achieves a significant increase in productivity with a given size of mixing chamber as compared with prior two-wing rotors.

Abstract: A method of manufacturing a corrugated tube is disclosed, wherein an axial load is applied from both ends of a primary tube (1) while locally heating the primary tube by use of a high frequency coil (34) in the peripheral direction, and the heated portion is thereby bulged. The application of load is stopped almost concurrently with termination of the heating process. The heated portion is forcibly cooled with a cooling liquid, thus molding one crest. Then the primary tube (1) and the high frequency coil (34) are relatively moved. The next crest is formed by repeating the foregoing steps. Such operations are consecutively repeated in the axial direction of the primary tube, thereby obtaining a corrugated tube formed with crests having a large amount of bulge and a small pitch. Apparatus for molding a corrugated tube is also disclosed.

Abstract: Primärzellen mit negativen Lithiumelektroden, positiven Elektroden aus Chromdioxid (CrOx, wobei 2,0 <= x <= 2,9), lassen sich unter Verzicht auf einen konventionellen Scheider zwischen den Elektrodenpolaritäten herstellen, weil sich in der Kontaktzone von selbst eine dünne Trennschicht aus Reaktionsprodukten des CrOx mit dem Li bildet, welche die Separatorfunktion übernimmt. Diese Trennschicht ist ionenleitend, nicht aber elektronenleitend, und besitzt einen geringeren ohmschen Widerstand als ein sonst verwendeter PP- oder Papierseparator. Dadurch ergibt sich eine höhere Strombelastbarkeit, die auch bei Zellen mit anderen Metalloxidkathoden wie MnO2, AgO, Ag2O oder Ni(OH)2 erzielt werden kann, sofern diese nur mit einer Deckschicht aus CrOx ummantelt sind.

Abstract: Encrypted messages are passed between selected pairs of user terminals 10, 10A, etc in a secure messaging system. A link is first established between the two terminals of the pair, one terminal sending a request to a key distribution centre KDC 12, which then provides encrypting keys to both terminals so they can communicate with each other. (Messages involving the KDC are themselves protected by encryption). In the present invention, the keys sent out by the KDC are key transporting keys, which are used by the terminals solely to transport data transporting keys between each other. The data transporting keys are used to transport (encrypt) the actual messages, and for security are changed after a usage count is reached; a fresh data transporting key is then generated and transferred under the key transporting key. This minimizes the load on the KDC. A hierarchy of key transporting keys can be used. The KDC (but not the user terminals) maintains a log to enable recovery after a system failure. A journey key can be generated to allow a user temporary access to a link from a third terminal.

Abstract: Apparatus is disclosed for introducing a precompensation delay in the path of a data signal to be written onto a magnetic medium, such as a floppy or hard disk. The apparatus includes a current controlled oscillator made up of delay elements having current control nodes, and means for controlling the current level being drawn from the current control nodes. The latter means includes three matched voltage controlled current sources having their outputs connected through a current splitter to the current control nodes, and bypass transistors for decoupling two of the voltage controlled current sources in response to a delay selection signal indicating whether the subject data pulse should be precompensated early, nominal or late. A current mirror arrangement with a current transfer ratio adjustable through the choice of two external resistors adjusts the current outputs of two of the voltage controlled current sources, so that the current level drawn from the current control nodes is different depending on which of the voltage controlled current sources is (are) selected. The apparatus also includes a master voltage controlled oscillator, located on the same chip as the above-described apparatus, with characteristics and a control voltage matched to those of the above-described apparatus. If the frequency of the master oscillator is phase locked to a multiple of the bit cell frequency, then the choice of the two external resistors adjusts the precompensation delay period as a continuous percentage of the bit cell time.
