Title: Light-stabilised flameproof styrene homopolymers and copolymers
Inventor: GILG BERNARD
IPC: C08L55/02
Filed: 1997-12-11
Abstract: The invention relates to a composition, comprising a) a styrene, .alpha.methylstyrene or p-methylstyrene homo- or copolymer; b) a bromine-containing flame retardant; c) a UV absorber; d) a sterically hindered amine and e) an epoxidised fatty acid. This invention also relates to the use of the light stabiliser mixture consisting of the components c), d), and e) for lightstabilising a styrene, .alpha.-methylstyrene or p-methylstyrene homo- or copolymer finished with a bromine-containing flame retardant as well as to a process for the light-stabilisation thereof. Adding an epoxidised fatty acid to a UV absorber and a sterically hindered amine in styrene, .alpha.methylstyrene or p-methylstyrene homo- or copolymers finished with brominecontaining flame retardants results in an unexpected synergistic effect in the light stability. In particular, it is possible to markedly reduce the discoloration of the finished polymer which takes place in the course of irradiation.
Patent CA-2272425-A1 (CA)
Title: Processor-controlled system and method of operating a processor-controlled system
Inventor: JAEKEL HANS-JOERG
IPC: G06F9/448
Filed: 1999-05-19
Abstract: In a system (SYS) controlled by a processor by means of a control program, the control program consists of several hierarchically arranged functional layers (LAYER1-4). Each of the program layers provides services, at least part of the services of a higher program layer building on services of a lower program layer. The program layers are linked asynchronously, such that a request (REQ) received from a higher program layer is responded to by sending a confirmation (CONF) before the request (REQ) is forwarded to a next lower program layer. As a result, the program layers are separated with respect to the time sequence of the program run. Advantageously, each of the program layers (LAYER1-4) has a memory (DB1-4) associated with it in which configuration data of the respective program layer are stored. A request (REQ) is first processed locally in a current program layer by updating the configuration data in the memory.      Then, the confirmation (CONF) is sent, whereupon the request is forwarded to the next lower program layer for further processing.
Patent CA-2272968-A1 (CA)
Title: Method for obtaining nmr bound fluid volume using partial polarization
Inventor: SPEIER PETER
IPC: G01V3/32
Filed: 1999-05-20
Abstract: The present invention provides methods for determining the bound fluid volume (BFV) of a formation utilizing nuclear magnetic resonance (NMR) techniques in which less than full polarization occurs and in which less than a complete NMR distribution is acquired. The effect of the polarizing static magnetic field is shortened in time by applying a shortened wait time between NMR measurements so that only the bound fluid of the formation is polarized. The shortened wait time is effectuated by early application of the oscillating magnetic field to the formation which, in conjunction with a limited number of refocusing pulses, induces signals in the formation that are measured by the NMR tool. The peak amplitude of these signals corresponds to the BFV. By only polarizing the bound fluid of the formation and only requiring a limited number of refocusing pulses, the NMR methods of the present invention are capable of providing BFV at high logging speeds such as those in excess of 1,800 feet per hour without a substantial degradation of vertical response.      The present invention provides information so that a partial polarization calculation curve in T, lies almost equally between an empirical tapered cutoff curve and a theoretical tapered cutoff curve. Moreover, because no T, information must be acquired, the method is especially suited for logging-while-drilling operations, where the drill string moves uncontrollably during the NMR measurement.

IPC: A61F11/00
Filed: 1998-03-10
Abstract: An implantable cochlear electrode array includes an electrode carrier, a groove within the electrode carrier, and a flexible element located in the groove. After the electrode array is implanted, the flexible element may be held in place while the electrode carrier may be partially withdrawn so that the electrode carrier pulls away from the flexible element which emerges from the groove through the surface of the electrode carrier, except where the electrode carrier and the flexible element are attached, so that the electrode carrier wraps around an inner scala tympani wall. A portion of the apical end of the electrode carrier may extend beyond the ends of the groove and the flexible element so that the apical end of the electrode carrier does not wrap around the inner scala tympani wall when the electrode carrier is partially withdrawn after insertion in the cochlea. The electrode carrier may include a perimodiolar section to be positioned next to an inner scala tympani wall of the cochlea, and an outer wall section to be positioned next to an outer scala tympani wall of the cochlea. Theperimodiolar section may be shorter than the outer wall section to accommodate the real length difference between the inner and outer walls of the scala tympani of a cochlea. Preferred embodiments are also directed to a method of fabricating such a cochlear electrode array by negative casting, and to a method of implanting such a cochlear electrode array.

Filed: 1999-12-07
Abstract: This invention is a new communication system in which multichannel broadcast digital services are distributed to each user with the broadcast video signal riding in the passband above a digital baseband signal. The system can deliver more than 1 Gbps additional bandwidth to each subscriber. The passband bandwidth will accommodate growth in downstream services including video on demand, higher speed web downloads including improved streaming audio and video, HDTV, interactive video, and personalized video. The invention requires only a single transmitter, a single transmission fiber and a single receiver for each user. A single transmitter, single fiber, single receiver system is much less expensive than two systems, one transmitting baseband and the other passband. A single receiver is greatly cost beneficial to achieving an economical fiber to the home solution where equipment at the end user location is not shared among multiple end users.     In an exemplary embodiment, an optical communication system comprises a diplexer for electronically combining the baseband and passband signals, a digital laser transmitter for generating an optical signal containing the combined signals, a length of optical transmission fiber for transmitting the optical signal, and, for each user or group of users, an optical receiver coupled to the fiber.

Abstract: A method of verifying the validity of a postal stamp to determine whether the stamp is produced legitimately and whether it has been canceled in a previous use. The method includes the steps of producing a special code on the stamp of interest and creating a record relating to the special code in a database. When the mailpiece collected by a post office has a stamp bearing a special code, the special code is reported to the database for verification. If the records in the database indicate that the reported special code does exist, then the stamp is considered legitimate. The mailpiece is accepted and the stamp is canceled before delivery, and a request is sent to the database to effect the alteration of the record relating to the "canceled" special code. An altered record will no longer provide a proof of validity if the database is later consulted with respect to the specific special code.
