Inventor: ROBBINS CLYDE N
IPC: H04N7/16
Filed: 1984-06-11
Abstract: An encrypted video distribution system includes a signal- originating head end for scrambling outgoing television program-bearing signals. In particular, the video content of selected lines is inverted about a reference voltage level, and the inversion reference level amplitude transmitted in pulse form during the horizontal synchronizing pulse interval. Line video inversion/non-inversion is controlled by a keyed pseudo random generator. 
     At each authorized subscriber location, all inverted lines are restored to proper format, using the accompanying received inversion amplitude level present during horizontal sync as a reference. A pseudo random generator is included in the receiver descrambling circuitry and operates in a sequence identical to the like circuit atthe head end to identify those lines requiring video inversion.

Abstract: A decoder for Manchester encoded data signals in which the encoded data signals (PRICHL) are applied to a first circuit (12, 14) which produces a primary pulse (PRIPUL) at each voltage transition of the applied signals. The primary pulse enables a delay line oscillator (20) which after a predetermined period of delay produces a decode clock signal (DECCLK) of a given frequency. The inverted primary pulse, the decode clock signal, and a constant voltage data input signal (Hi) are applied to a decoder shift register (16). The primary pulse and selected outputs of the decoder shift register are applied to a logic circuit (48) which produces a receive clock signal having desired low-to-high voltage transitions occurring substantially in the center of each half-bit cell of a Manchester bit cell. The receive clock signal can be applied to a receive data shift register (40) to which the encoded data signals are also applied so that the binary value of each half-bit cell of a Manchester bit cell can be stored in the data shift register (Fig. 1).

Abstract: The system comprises an input section (20), a knowledge accumulation section (18), a work domain section (16), storage means (14) and inference processing means (12). Attributive information is supplemented in a knowledge unit for the purpose of smooth execution of inference, and a knowledge base is constructed with this pair as the building unit. In connection with this, functions that are in response to the purpose, such as selection or rejection of a knowledge unit and alteration in the order of search, are added to the interference organ (12), based on the attributive information. Employed as an attributive information is, for example, the information on the frequency of use of each knowledge unit. The inference organ (12) renews the information on the frequency of use for every use of each knowledge unit. In addition, a storage space (14) is allocated to each knowledge unit based on the information on the frequency of use. This means, for example, that a knowledge unit with higher frequency of use is stored in an area of the inference organ that may be accessed with ease (the core memory or the like).

Abstract: A supported silver catalyst for the oxidation of ethylene to ethylene oxide with molecular oxygen is made by impregnating a support with a hydrocarbon solution of a silver salt of a neo-acid having 7 or more carbon atoms, the solution being substantially free of water and said neo-acid. Preferably, the hydrocarbon solvent is toluene, xylene, ethyl benzene, cyclohexane, or cumene. The impregnated support is dried and the silver is activated under conditions chosen to provide the optimum selectivity to ethylene oxide. Thereafter, the activated silver catalyst may be impregnated with an alkali metal solution sufficient to increase selectivity of the silver catalyst above its alkali-free state. The amount of alkali metal on the finished catalyst is the optimum for the particular support selected and preferably will be about 1-6 x 10 -3  gew/kg of catalyst. The catalyst may also include additional promoters, such as the alkaline earth metals, preferably barium.

Abstract: In a circuit arrangement comprising a power source circuit (12) and a phase detector (22), a phase difference signal (PD) is supplied to a first switch (31) repeatedly turned on and off during battery saving operation and to a second switch (32) initially turned on simultaneously with the first switch. First and second intermediate signals are sent through first and second low-pass filters (41, 42; 43, 44) as first and second modified signals (MO, and M0<sub>2</sub>), respective-' ly, to a voltage-controlled oscillator (25). A bidirectional nonlinear circuit (36, 37) becomes conductive and also sends the second modified signal to the voltage-controlled oscillator when the first intermediate signal becomes high. The voltage-controlled oscillator produces an oscillation signal with a high sensitivity on supply of both the first and the second modified signals and with a low sensitivity on sole supply of the first modified signal. Such different sensitivities serve to make the circuit arrangement rapidly and stably carry out the battery saving operation.

Abstract: A method is disclosed for producing ammonium metatungstate from ammonium paratungstate. The method involves first roasting the ammonium paratungstate at from about 275° to about 300°C for from about 10 hours to about 20 hours to remove some ammonia and some water. The roasted ammonium paratungstate is then added to dilute solution of an ammonium metatungstate which is at a pH of from about 3.6 to about 4.2, the rate of addition being such that a slurry is produced having a pH of from about 3.6 to about 4.2. The pH of the resulting slurry is then adjusted to stabilize it at from about 3.6 to about 4.2 followed by evaporation to form a relatively concentrated solution of ammonium metatungstate which is then separated from any insolubles. Ammonium metatungstate is then crystallized from the relatively concentrated ammonium metatungstate solution.

Abstract: A first-in, first out data memory minimizes fall-through delay. The FIFO memory has a plurality of cascaded register stages (50) arranged in sections, with the input of each section selectively coupled to a bypass bus (40). Data is introduced on the bypass bus, and control logic (48) writes the data into the section nearest the output which is currently not full. The individual register stages are self-clocked, so that data is then shifted toward the output through any vacant registers. In another aspect, the register stages (60) are arranged in sections of different length, with the shortest section closest to the output and the longest section closest to the input. De- cressed fall-through delay is achieved by minimizing the length of the FIFO buffer actually traversed by the data while insuring that the order of the data remains unchanged.

Abstract: Bei einer Regelung eines Kettbaumantriebs einer Webmaschine wird wenigstens in Abhängigkeit von einer die Drehzahl des Kettbaumes und einer die Spannung der Kettfäden darstellenden Größe der Kettbaumantrieb beeinflußt. Ist aufgrund eines aufgetretenen Fehlers die Webmaschine zum Stillstand gekommen, so wird vor einem Wiederanfahren des Kettbaumantriebs die Spannung der Kettfäden durch Zurückdrehen des Kettbaumes auf einen bestimmten Wert erhöht, um diese Kettfadenspannung während des Anfahrens durch entsprechendes Einwirken auf den Kettbaumantrieb auf einen vorbestimmbaren Normalwert wieder zurückzunehmen. Dies bewirkt, daß durch den Stillstand der Webmaschine im Webgut keine Stopmarken bzw. Anlaßmarken entstehen. Verwirklicht wird diese Regelung mit Hilfe eines digitalen Rechners, dem die Drehzahl des Kettbaumes mittels eines Impulsgebers und die Spannung der Kettfäden mittels eines die Stellung eines Tänzers abgreifenden Weggebers zugeführt ist. Dabei wird das vom Impulsgeber dem Rechner zugeleitete Signal nicht nur als Drehzahlsignal verwendet, sonderns insbesondere beim Erhöhen der Spannung der Kettfäden auf den bestimmten erhöhten Wert auch als Wegsignal.
