Disclosed is a method and apparatus for determining stone cells within a sample of wood pulp or paper. According to the instant invention a portion of the sample is irradiated with light at a predetermined wavelength or within a predetermined range of wavelengths. The incident light causes those areas of the sample that are occupied by stone cells to fluoresce strongly relative to the background ...

Spherical balls, notably microballs of welding alloys, are produced by passi ng a melted material through vibrating orifices (8) of a granulation pot (4), in order to form droplets which solidify when falling, by gravity, into a cooling tower (16) filled with an inert gas. To improve the surface condition of the balls, the inert gas comprises approximately 15 to 150 ppm of oxygen. Moreover, the ...

The invention relates to a line for processing an optical fiber having first and second ends, the line comprising a support for receiving a reel with the fiber wounded thereon; a de-winder for unwinding the fiber without substantial rotation of the reel; and a processing station for receiving the optical fiber from said de-winder to perform a processing on a portion of the optical fiber. The inven...

A roof membrane welding apparatus capable of applying a weld to a first membrane and an overlapping second membrane. The apparatus includes a movabl y supported chassis, a welder attached to the chassis for heating the top membrane to at least the vicant softening point to weld the overlapping second membrane and the first membrane, and at least one weld wheel rotatably attached to the chassis an...

SE REFIERE A UN CONTENEDOR QUE EXPANDE PANELES SOLIDOS ARTICULADOS PARA CONVERTIRSE EN UN MODULO HABITABLE, DONDE LA CONEXION ENTRE MODULOS PERMITE LA FORMACION DE COMPLEJOS HABITACIONALES. PERMITIENDO ADEMAS SU FACIL TRANSPORTE DENTRO DEL CONTENEDOR QUE FORMA PARTE DE SU ESTRUCTURA. DONDE LA EXTENSION DE LOS PANELES SE LLEVA A CABO MEDIANTE UN MECANISMO MANUAL, USANDO UN BIPODE CABLESTANTE PLEGAD...

An apparatus for covering a glucose meter is described, wherein the glucose meter has a front surface opposed to a back surface, and an edge surface connecting the front surface to the back surface. The apparatus comprises a frame adapted to receive the glucose meter and at least one attachment mem- ber connected with the frame. The frame is adapted to sur- round a substantial portion of the edge ...

A system for time validation comprises a termi- nal (1) with means (7,7') for tuning in to a number of different carrier frequencies (a-e), an authorisation de- vice (6), e.g. a smart card, capable of communicating with the terminal (1) and means (2,5) to transmit time stamps, using a modulated signal having a carrier frequency, to the terminal (1). The authorisation device (6) comprises means (8)...

A communication structure and method which allows connection-like and connectionless communications to be provided on a multiplexed link is provided. The structure and method can make efficient use of available transmission capaci ty and/or network resources while providing both types of communication and hybrids. Connection-like communications can be provided by a dedicated code divisi on multip...

Systems, devices, and methods are disclosed in which Wnt activity modulato rs promote myogenesis for treatment or diagnosis of medical conditions, tissue repair, or creation of experimental models.

In order to improve detecting accuracy in a gas leak detection for a fuel ce ll (1), in a gas leak detection method for a fuel cell having a solid polymer electrolyte membrane (51) sandwiched by an anode (52) and a cathode (53), an output voltage is measured in an activated over-potential region in a state in whic h the pressure of fuel gas which is supplied to the anode (52) is maintained higher ...

A method for polling a plurality of wireless modems from a base station in which the base station individually polls all of the modems and forms at lea st two lists such that each modem is identified on only one discrete list based upon its behavior in response to the polling. Thereafter, the modems identified on each discrete list are polled at a rate that may differ from the rate at which the mo...
