Title: Silver-containing supported catalysts and catalyst intermediates, processes for their preparation and their use
Inventor: VOLPRECHT WERNER
IPC: C07D301/10
Filed: 1999-01-26
Abstract: The present invention relates to silver-containing and optionally promoter-containing supported catalysts and catalyst intermediates, processes for their preparation and their use for preparing alkylene oxides by oxidation of alkenes with oxygen. The catalysts are prepared by treatment of a support with a lactic acid containing silver ions, nitrate ions and optionally promoter metal ions, drying, predecomposition in a virtually oxygen-free atmosphere and subsequent activation by heating in an oxygen-containing atmosphere while precisely controlling the temperature conditions and the feeding-in of oxygen. The catalyst intermediates obtainable by treatment, drying and only predecomposition can be activated in a temporally and physically separate process step to form the actual catalysts.      Suitable promoters are alkaline earth metal compounds and/or alkali metal compounds. High activities and high selectivities are achieved when using the catalysts of the invention for preparing alkaline oxides.
Patent CA-2260522-A1 (CA)
Inventor: GANS MICHAEL JAMES
IPC: H04B1/707
Filed: 1999-01-28
Abstract: A CDMA communication system is disclosed offering a near continuum of data rates up to a maximum rate. The disclosed CDMA communication system increases the data rate variability, without disturbing the orthogonality between users. An increased number of data rates is obtained by time multiplexing the data rates achievable with conventional CDMA systems to provide additional data rates for various multimedia applications. If a user is assigned a specific orthogonal code sequence, such as a Walsh sequence, which permits a maximum data rate, n R, with conventional systems, the user can obtain additional desired data rates up to the maximum rate n R, by time multiplexing the specific orthogonal code set.  Desired bit rates are achievable for applications requiring bit rates that are not an integer multiple of the rates provided by conventional techniques. A fundamental rate of R or "fat pipe" rates of powers-of-two multiples of the fundamental rate can be achieved in a conventional manner. A desired rate up to the maximum "fat pipe" rate is achieved by time multiplexing the codes w k n to achieve rates between R and nR, where w k n, denotes the first nth of the spread spectrum code w k. The transmitter of the present invention achieves a rate conversion to match the appropriate codeword to the appropriate data rate, by employing buffering and reclocking of the data, with time multiplexing of the orthogonal Walsh codes corresponding to the available lower and upper rates. The rate conversion must be synchronized with the selection of the orthogonal Walsh code (corresponding to the lower and upper rates).

Title: Apparatus and method for midspan access of encapsulated optical fibers
Inventor: FITZ JONATHAN G
IPC: G02B6/00
Filed: 1999-03-30
Abstract: Midspan access to selected optical fibers which are encapsulated in an optical ribbon or tube is achieved by placing the desired span of the encapsulated fibers to be accessed between opposing abrasive layers and controllably urging at least one of the abrasive layers in the direction of the opposing abrasive layer to cause both abrasive layers to contact the encapsulant which covers the fibers. The amount of force applied to the at least one abrasive layer is limited by the structure of a resilient element which is coupled to the abrasive surface. Stress concentrators are created in the encapsulant and the encapsulant is removed from the span portion by relative movement of the encapsulated fibers and the abrasive layers. A minimum separation distance between the opposing abrasive layers can be defined, according to the thickness of the specific encapsulated fiber medium undergoing fiber separation, to avoid contact between the abrasive surfaces and the fibers within the medium. Access to the individual fibers is provided after the stress concentrators are formed in the encapsulant or encapsulant in the desired span portion has been substantially removed.
