  • Patent number: 6945709
    Abstract: An optocasule unit for an optohybrid assembly (10), said capsule unit comprising a lower casing part (36) and a compatible upper cover part (54) which together form, at one end (50) thereof, an integral receptacle section for obtaining an optomechanical interface and receiving and detachably holding therein an optical connector with at least one external optical fiber. A central section (38) of the lower casing part (36) has a cavity (42) for receiving, in a form-closed manner, a ferrule (12) of the optohybrid assembly (10). The lower casing part (36) has, at a second end thereof, a base plate (44) for supporting a substrate (20) having at least one optochip (26, 28) and a proximal end of at least one primary optical fiber (22, 24) mounted thereon. The cover part (54) also has a section (58) covering the substrate (20) and at least a portion of the base plate (44) of the lower part.

  • Publication number: 20040156149
    Abstract: An opto-mechanical interface apparatus includes an optical hybrid, an electronic hybrid adapted to receive electronic components, an adapter fixture for fixing the electronic hybrid and the optical hybrid to one another to form a combined hybrid, a lower-capsule part, and an upper-capsule part adapted to mate with the lower-capsule part. Mating of the upper-capsule part and the lower-capsule part encloses at least part of the combined hybrid. The apparatus forms an opto-mechanical interface for making external optical connection(s).

  • Patent number: 6096167
    Abstract: Process for the manufacture of a colored fibre material, containing a certain proportion of cellulose fibres, such as paper and nonwoven. A dyestuff is applied onto reel or sheet pulp either on the whole material or only on part of it, whereupon the reel or sheet pulp is defibrated and dispersed in liquid or foam possibly together with other fibres. The fibre dispersion is thereafter applied onto a wire and dewatered, whereupon the formed fibre web, which contains a substantially even addition of colored fibres, is subjected to possible further treatment steps before drying and reeling. A fibre material manufactured according to the process is also disclosed. If only part of the pulp fibres are colored, a mottled color impression of the material is obtained.

  • Patent number: 6037282
    Abstract: Nonwoven material produced by hydroentangling a fiber web, comprising recycled fibers with a fiber length of between 5 and 60 mm and a fineness of between 0.1 and 20 dtex, which are constituted by fibers which are mechanically shredded or torn from nonwoven waste, textile waste or the like. The fibers are mixed with each other and possibly with new fibers in a wet-formed, foam-formed, air-laid or dry-laid fiber web which is hydroentangled with sufficient energy for forming a compact absorbent material.

  • Patent number: 6017833
    Abstract: Nonwoven material produced by hydro-entanglement of a wet- or foam-formed fibre web, which material contains at least 5%, by weight of the total fibre weight, of pulp fibres of chemical-thermomechanical type. These fibres have been mixed with other fibres, such as chemical pulp fibres, vegetable fibres, synthetic fibres or regenerated cellulosic fibres in a wet- or foam-formed fibre web which has been entangled with sufficient energy to produce a dense, absorbent material.

  • Patent number: 5958186
    Abstract: Nonwoven material produced by hydroentanglement of a wet-laid or foam-formed fibre web. The material comprises a mixture of short plant fibres, in particular pulp fibres, and long hydrophillic plant fibres, where the major portion of the fibres presents a fibre length which is at least 10 mm, whereby the portion of long fibres is at least 1 weight-% of the fibre weight. The fibres were mixed with each other in the presence of a dispersing agent which allows a uniform fibre formation, in a wet-laid or foam-formed fibre web which has been hydroentangled with sufficient energy to form a compact absorbing material.
