A well logging device comprises a relatively small diameter device constructed to withstand high temperatures and pressures, this device comprising a continuous stainless steel tube which provides pressure resistance and also allows low energy gamma ray transparency via large and small windows.

A remote tire pressure monitoring system includes a sending unit for each monitored tire, and the sending units transmit RF signals, each including an identifier ID(i) and a pressure indicator P(i). A receiver operates in a learn mode in which the receiver associates specific identifiers either with the vehicle or with specific tires. During the learn mode the vehicle is driven at a speed above a ...

A detachable pulley cover structure is provided for use with a rotary mower. The structure includes a generally circularly shaped composite cover member adapted to fit flush with the top of a mower deck and shield the pulley drive area, headed pin means fixed to the mower deck are received in slotted openings which are radially spaced about the cover member to permit the cover member to be quickly...

A device for a riding mower having a wheel born chassis intended to support the operator, an engine for driving at least one wheel and cutting means (31) arranged in a front mounted cutting unit (17). The cutting unit is placed such that at least a part of the cutting unit is situated close beneath the front part of the chassis. The mower is provided with a first pivot (26) arranged in front of th...

Moulding based on silica, existing in a hollow cylindrical configuration with internal reinforcing stays or spokes leading from the inner wall of the hollow cylinder to the centre of the moulding or in the form of what are termed miniliths, are produced by homogenising silica with methyl hydroxyethyl cellulose, wax and/or polyethylene glycol with the addition of water and optionally with the addit...

A navigation system and method for viewing a data landscape in an information visualization system employs constraints and positions for the rendering viewpoint which are defined relative to a bounding box enclosing objects within a volume of interest. The bounding box is resized to reflect changes in objects within the volume of interest including the addition or deletion of objects and/or the re...

La présente invention se rapporte à des compositions cosmétiques et/ou dermatologiques destinées à produire sur la peau une coloration artificielle proche du bronzage naturel, comprenant dans un support sous forme d'émulsion eau-dans-huile plus de 2% en poids d'au moins un nanopigment d'oxyde de fer dont la taille moyenne des particules élémentaires est inférieure à 100 nm. L'invention porte aussi...

A method for multiplexing and demultiplexing commercial and program material within the context of, e.g., an MPEG1 or MPEG2 information distribution system. A system employing the method provides either a single terrestrial broadcast channel or a "virtual head-end" as part of an uplink site which encodes advertising materials, associates the advertising material with "tags" indicative of demograph...

A closed-loop ultrasonic welding apparatus for sealing or welding thermoplastic material on a continuous basis wherein the material to be welded is fed through a weld station comprising a horn and anvil. The apparatus includes means for providing a first signal commensurate with a desired ultrasonic energy density in the material when welded, a second signal responsive to the feed speed of the mat...

A battery separator is a polypropylene microporous membrane, made from a beta-nucleated precursor, and having an electrical resistance of less than 30 ohms-inches per mil, and a puncture strength of greater than 400 grams-force per mil.

Reduced performance of a fuel cell formed of a plurality of stacked unit cells caused by unequal gas flow rates in the unit cells is avoided through the use of separators, each having a plurality of through holes extending therethrough and a recessed portion formed in a surface of each separator. In a fuel cell incorporating such separators, the recessed portion of each separator forms an in-cell ...

The present invention relates to multi-wavelength filtering devices and more particularly to a multi-channel multiplexer/demultiplexor using at least one multi-port optical circulator and a plurality of Bragg optical fiber gratings or other wavelength selective means. Advantageously a drop or add/drop optical circuit including the combination of a Bragg grating providing a strong reflective respon...

A method for awarding bonuses over a gaming network having a plurality of gaming machines interconnected by a network. Play is allowed to occur on the plurality of gaming machines. A bonus period is initiating for which a bonus-triggering event (e.g. a winning combination) and an initial bonus amount is determined. The reel combinations obtained from normal play over the machines are detected and ...

The portable computer can be fixed to a panel (1) containing pairs of fastener holes (2), through which two locking bolts (4) can be passed to secure the computer against the panel, which can then be securable to another object.

The invention relates to a device and a method for switching optical wavelength channels. Said optical wavelength channels are introduced into at least one access waveguide provided on a first side of a first multi-mode waveguide (10). Subsequently, the wavelength channels are transmitted through said multi-mode waveguide (10) and projected on at least two connection waveguides provided on the opp...
