Abstract: A cable guide or cleat for a cable, comprises, in one embodiment, a pivot mounting, a base section on the mounting and an upper section that, when fastened to the base section, a cylindrical guide with clearance for a cable to be passed through the guide for installation, and an insert piece designed to be inserted when the cable is in its final position, so that the base and upper sections, clamp the cable in place. The clearance allows the cable guide to be used first without the insert, when laying the cable, facilitating the laying of the cable round bends in particular. Then, when the cable is in place, the cleat is released again and the insert put in place, so that when the cleat is fastened the cable is securely clamped. Disclosed systems obviate the need for separate temporary guides that would otherwise need storing.

Abstract: The invention is directed to purified and isolated novel ULBP polypeptides, the nucleic acids encoding such polypeptides, processes for production of recombinant forms of such polypeptides, antibodies generated against these polypeptides, fragmented peptides derived from these polypeptides, and the uses of the above. ULBP polypeptide can be found on the surface of human B cell lymphomas. Mammalian forms of ULBP polypeptide in isolated or purified forms are provided. In addition, isolated nucleic acids encoding ULBP polypeptides and expression vectors comprising a cDNA encoding ULBP polypeptides are provided. The ULBP polypeptides can be isolated or synthesized and used to prepare antibodies, and in particular monoclonal antibodies, against the polypeptides. The antibodies, in turn, are useful for detecting the presence of ULBP polypeptides in human cell samples, which can be correlated with the existence of a malignant condition in a patient.

Abstract: A resonant laser device including first and second reflectors defining an optical cavity with given optical resonance characteristics. The laser device including a laser active material in a first optical fiber disposed between the reflectors in the cavity and a second photosensitive optical fiber coupled to the cavity. One of the reflector being a refractive index grating formed in the second fiber such that the laser operates with a selected predetermined wavelength and the laser being tuned to a different wavelength by exposing the second fiber to a second spatially periodic pattern of optical radiation such that the second pattern becomes recorded in the second optical fiber.

Abstract: A laser includes first and second feedback elements defining a laser cavity, and a gain medium within the laser cavity. The gain medium has first and second facets and an optical waveguide for guiding optical radiation between said first and second facets. The second feedback element is wavelength selective, and the optical waveguide is configured to direct optical radiation at an angle .theta. to the normal of the second facet.
