  • Publication number: 20050268673
    Abstract: A device for protecting a computer peripheral against unauthorized removal includes a signal cord-holding portion (23; 84, 85; 173) having a signal cord holding passage (26; 76, 126). The signal cord holding portion (23; 84, 85; 173) is transformable between an open condition for receiving the signal cord (11, 12; 111, 112) in the signal cord holding passage (26; 76, 126; 176) or releasing the signal cord (11, 12; 111, 112) and a signal cord holding condition for preventing removal of the signal cord (11, 12; 111, 112) without dismounting from a connector or peripheral (9, 10, 27, 28; 127, 128). A connecting structure (25; 75; 142, 143; 175) is provided for connecting the device to an object. The signal cord holding portion (23; 84, 85) and the connecting structure (25; 75) are interconnected for securing the signal cord holding portion (23; 84, 85) in the signal cord holding condition if the connecting structure (25; 75; 142, 143; 175) is connected to an object (2; 30).

  • Publication number: 20050207112
    Abstract: A desktop stand for a docking station and a portable computer having a keyboard member and a display panel projecting from a rear end portion of the keyboard member. A fastener structure is provided for fastening the docking station to a support structure for supporting at least a portion of the keyboard member. An abutment for engaging the end of the keyboard member remote from the display is located at a distance of and faces the fastener structure when in operative position for fastening the docking station to the support structure. When in fixed condition, the fastener structure or the abutment is releasably fixed and, when in a released condition, allows adjustment of the distance from the abutment to the fastener structure.

  • Patent number: 6880212
    Abstract: A continuous method for producing composite elastic yarns at speeds up to 700 m/min by (a) stretching (drafting) an elastomeric yarn (e.g., spandex) by 2.0× (100%) to 10.5× (950%) while heating (max. heating temperature 220° C.) in a single or double stage draft, (b) air-jet entangling with a relatively inelastic yarn component to create a composite elastic yarn, and then (c) in-line heat-treating (max. heating temperature 240° C.) the composite elastic yarn. The initial draft stage(s) may also be carried out at ambient temperature. The resulting composite elastic yarn has improved stitch clarity, particularly suited for hosiery, and its properties can be tailored to provide fabric properties for knit and woven fabrics hitherto not possible with standard spandex yarns.

  • Patent number: 6476185
    Abstract: The invention pertains to a process for the preparation of an organic compound by a condensation reaction in which besides the organic compound other products are formed and one or more of the products formed during the preparation are extracted from the reaction mixture with the aid of a membrane. The reaction is carried out at a temperature above 80° C. and one or more of the products formed during the reaction are extracted from the reaction mixture by the aid of an inorganic membrane with an average pore size of the separating layer of less than 0.5 nm.

  • Patent number: 6290952
    Abstract: The invention relates to pharmaceutical compositions suitable for treating or curing clinical complications mediated by endotoxin, including sepsis. The compositions contain components suitable for detoxifying endotoxin rendering it less deleterious to mammals such as humans, in particular to patients with reduced host-defence resistance. The invention also relates to pharmaceutical compositions suitable for stimulating bone formation, e.g. for mending broken bone or for prophylaxis or therapy of metabolic bone diseases such as osteoporosis and osteomalacia and pharmaceutical compositions for decreasing or inhibiting undesired bone formation. The pharmaceutical compositions according to the invention are directed at modulating phosphatase activity in vivo.

  • Patent number: 5362432
    Abstract: A process is provided for dry spinning a segmented polyurethaneurea at speeds as high as 900 meters/min. The process includes chain-extending an isocyanate-capped polyether glycol with a mixture of ethylenediamine and 1,2-diaminopropane, the 1,2-diaminopropane amounting to 8 to 17 mole % of the diamine mixture. The resultant spandex is particularly suited for use in women's hosiery.
