Title: Semiconductor laser element having a diverging region
Inventor: MORASCA SALVATORE
IPC: H01S5/20
Filed: 2000-12-20
Abstract: A semiconductor ridge laser for coupling to a single-mode optical fiber has a ridge with a narrow parallel region, a diverging region, and then a wide parallel region that is adjacent to an output facet. A pump region for the laser may be less than the entire area of the ridge and have a "T" shape. Preferably, the ridge has a depth of about 350 to 550 nm and the narrow parallel region has a length of more than 0.4 times the overall length of th e ridge. The wide parallel region at the output enables the laser to obtain lo w thermal resistance, which leads to a low operating temperature, a low power density in the laser cavity, and low astigmatism.

Title: One component thermoset polyurethane system
Inventor: JOSHI RAVI R
IPC: C08K3/40
Filed: 2001-08-17
Abstract: A process for the preparation of fiber reinforced composites in which the matrix polymer is derived from the catalyzed reaction of a liquid polyisocyanate containing material. The principle curing mechanism is the formation of urethane and/or isocyanurate linkages. At least a portion of the catalyst is applied onto the surface of the reinforcing fibers and/or onto the surface to the uncured resin impregnated reinforcing structure, under conditions such that the catalyst is not dispersed into the bulk of the isocyanate containing resin until cure. Curing is facilitated by a combination of mechanical and thermal action. The process is particularly well suited for the preparation of composites by pultrusion, using a one-component open-bath pultrusion machine. The process of the invention may be adapted to a much wider range of composite fabrication methods, including SMC and filament winding.

Title: Method and apparatus for web threading in a drying section of a paper machine or similar
Inventor: KOMULAINEN ANTTI
IPC: D21G9/00
Filed: 2001-10-26
Abstract: A method and an apparatus for web threading in a drying section of a paper machine or the like. A leader (24) and a so called run-down strip are formed by cutting in the web coming to the drying cylinder in the drying section. An underpressure box (18) is arranged at the opening gap between the drying cylinder (14) and the drying wire, on that side of the wire which is away from the web, whereby this box can direct against the web an underpressure which is controllable in the machine's cross direction. The underpressure box creates an underpressure region (34') between the leader and the underpressure box, the region having an underpressure p1 at the detachment point, i.e. in the area where the wire is detached from said drying cylinder (14), which underpressure is sufficient to detach the leader from said drying cylinder. A  protection zone is created between the underpressure region created at the leader and the run-down strip, which protection zone has a barrier (46) in order to maintain the underpressure p1 in the underpressure region.

Title: Detachable accessory holder
Inventor: HOLSTEN STUART V
IPC: A47L9/00
Filed: 2003-04-30
Abstract: The present invention provides a holder for storing accessories on a wet/dry vacuum. The holder securely attaches to the vacuum and readily detaches therefrom. The detachable holder may be detached with the accessories. While an operator dumps debris out of the drum of the vacuum, detaching the holder prevents the accessories from being inadvertently spilled out of or discarded from the holder. The detachable accessory holder fully secures to a bracket attached to the vacuum. The secure attachment prevents the holder from falling off or tipping on the vacuum. To attach the holder to the bracket and vacuum, grooves on the holder are set on to an axle of the vacuum. As the holder is pivoted about the axle, tabs and a latch on the holder engage slots and a step on the bracket. To remove the holder, the operator presses on the latch and lifts the holder from the bracket and the appliance.
