Title: High performance tire tread rubber composition
Inventor: BLOK EDWARD JOHN
IPC: C08L9/00
Filed: 1999-07-19
Abstract: This invention relates to a tire tread compound that can be used in manufacturing tires having outstanding traction characteristics without compromising treadwear and rolling resistance. The tire tread compounds of this invention are made utilizing an isoprene-butadiene rubber having a high glass transition temperature and having SnR3 end groups, wherein R represents an alkyl group, such as a tertiary-butyl group. These isoprene-butadiene rubbers are made by reacting an isoprene-butadiene rubber having a glass transition temperature which is within the range of about -50°C to about 0°C with a tin compound of the formula SnR3X, wherein R represents an alkyl group and wherein X represents a halogen. This invention more specifically discloses a tire tread rubber composition which is comprised of (1) about 60 phr to about 95 phr of an isoprene-butadiene rubber having a glass transition temperature which is within the range of about -50°C to about 0°C and having -SnR3 end groups, (2) about 5 phr to about 30 phr of natural rubber and (3) up to about 25 phr of a rubbery polymer having a low glass transition temperature which is within the range of about -85°C to about -55°C, with the proviso that the total amount of the natural rubber and the rubbery polymer having a low glass transition temperature does not exceed about 40 phr. The rubbery polymer having a low glass transition temperature will typically be high cis-1,4-polybutadiene, isoprene-butadiene rubber, styrene-butadiene rubber or styrene-isoprene-butadiene rubber.

Abstract: L'invention concerne un procédé et un appareil d'exécution de transfert sûr inter-systèmes entre des systèmes de télécommunications (S1, S2) ou de transfert sûr interfréquences dans un système de télécommunications AMDC. L'objectif de cette invention est de réduire la probabilité d'appels perdus pendant un transfert sûr inter-systèmes. Dans le cas où une tentative de transfert sûr est infructueuse, la station mobile (18) revient au système d'origine (S1) au moyen d'informations que le système de télécommunications de la présente invention utilise pour aider à effectuer des tentatives de transfert futures. Dans un autre mode de réalisation, lorsqu'aucune tentative de transfert n'est effectuée, la station mobile (18) contrôle le système de destination (S2) puis revient vers le système d'origine (S1) au moyen d'informations utilisées pour aider aux tentatives de transfert ultérieures. Les informations renvoyées après contrôle d'un système AMDC se composent des résultats d'une recherche d'une ou plusieurs ondes pilotes données à des décalages dans une liste spécifique fournie à la station mobile (18) par la station de base (B1, B7) d'un ensemble de décalages basés sur un algorithme de recherche prédéterminé.

Title: Manufacture of self-made cigarette assemblies
Inventor: CHAMPAGNE MARCEL
IPC: A24C5/40
Filed: 1999-07-30
Abstract: Self-made cigarettes, i.e. tobacco products that are supplied in unsmokable condition in the form of a tobacco--bearing component comprising a tobacco rod attached to a porous filter at least part of the surface of which is highly permeable, and an impervious tubular band carried on the component and slidable along it to cover the permeable region. The tubular band can be applied by compressing the tobacco--bearing component to enable the preformed tubular band to be slid onto it. Tubular bands are automatically assembled onto tobacco bearing components by an apparatus that includes a rotary drum around the periphery of which are distributed sets of assembly tools each of which sets comprises a pair of opposed rods which are employed to introduce the tubular band and the tobacco bearing component into opposite ends of an assembly cylinder wherein the band is slid onto the tobacco component, the assembled product subsequently being ejected. The components are fed into the successive assembly tool sets as the latter are rotated on the drum past a feed point, actuation of the rods being effected by means of stationary cams past which the rods are moved by rotation of the drum.

Title: Method for storing data in a chip card rewritable memory
Inventor: PERROT DANIEL
IPC: G06K19/07
Filed: 1998-02-13
Abstract: The invention concerns a storing method which consists in adding, to the elementary transparent (5) or record (4) files of fixed lengths designed by the ISO 7816-4 standard, elementary files of variable lengths (7) with capacity always adapted to the size of records which they store, and in managing this new type of files with micro-instructions observing the formalism of the ISO 7816-4 standard and pertaining to the class of owner instructions. This novel elementary file with variable length opens up the prospect of novel chip cards conforming to the ISO 7816-4 standard and using data compression techniques for data storage, which is particularly interesting in view of the limited storage capacity of a chip card.

Patent CA-2284900-A1 (CA)
Title: Orientation measuring instrument
Inventor: OKADA FUMIAKI
IPC: G01N22/00
Filed: 1998-03-25
Abstract: It is possible to generate a resonance mode such that a dielectric resonator (20) can be resonated and an electric field vector leaking out from the resonator (20) exists by arranging antennas (22a and 22b) for the resonator (20). When a sample (22) has dielectric anisotropy, the resonance frequency of the resonator (20) varies when the sample (25) or resonator (20) is rotated. The dielectric anisotropy of the sample (25) is found from the variance of the resonance frequency. Thus the dielectric anisotropy of not only a sheet-like sample, but also such a sample as a three-dimensional molded sample can be measured.

Abstract: First search codes for a public system are made common in the TDD and FDD systems. A mobile station decides on the connection or switching to either system by measuring received levels of both first search codes in the FDD and TDD systems. In private systems, a different first search code is used for each system.      Accordingly, the first search codes are made known in a terminal supporting also private modes. Between the private and public systems, a mobile station decides on the connection or switching to either system by measuring received levels of both first search codes in the private and public systems.

Title: A deflection circuit having a controllable sawtooth generator
Inventor: KOBLITZ KARL RUDOLF
IPC: H04N3/18
Filed: 1993-02-11
Abstract: In a vertical sawtooth generator of a vertical deflection circuit, a first comparator generates an output signal when a retrace portion of a sawtooth signal is at a first magnitude to initiate a vertical trace portion of the sawtooth signal. An amplifier responsive to the sawtooth signal generates a feedback current at a time that occurs more than one-half of the length of vertical trace portion after vertical trace is initiated. The feedback current is coupled to a capacitor to develop a capacitor voltage. The capacitor voltage is applied via a voltage-to-current converter to an integrating capacitor to develop in the integrating capacitor the trace portion of the sawtooth signal.
