Abstract: A centrifugal fan system for a building includes a centrifugal fan mounted for rotation about a vertical axis and having a bottom inlet. The fan is mounted in a movable housing having a fan chamber and an air outlet arranged in a side thereof. Wheels are mounted on both sides of the fan housing and engage two elongate track members, that extend horizontally and are mounted on a suitable supporting structure. Thus,  the fan and its housing can be moved horizontally away from the top of an input flow concentrator. The housing has an internal, perforated  scroll-shaped wall  and vertical  external walls.  Sound insulation is located between the scroll-wall and the external walls.   An electrical motor is mounted on the side of the housing and is connected to drive the fan

Abstract: Platine de commande (17) permettant de sélectionner et de commander les mouvements de tricotage des outils de tricotage d'une machine à tricoter, dont l'entraînement se fait par les mouvements relatifs d'un support de platine (11) et d'un support de came (12). Par l'action d'une prétension minimale du ressort de commande ayant la forme générale d'une barre allongée (37), dont l'extrémité libre repose coulissante au fond d'une rainure de guidage (16) recevant la platine de commande, cette dernière est amenée à prendre une position dans laquelle un pied de chasse (61) entre en contact avec un bord de chasse d'un élément came de chasse (73) du support de came (12) de façon à transmettre la force de déviation. La platine est configurée de façon à simplifier la fabrication et à accroître sa résistance à l'usure, en particulier son ressort de commande (37) est conçu comme une partie ressort en acier monobloc. La largeur (h) du ressort de commande (37) mesurée perpendiculairement à la ligne de flexion neutre (54), au niveau de la base du ressort sur laquelle celui-ci se raccorde au corps principal de la platine (18), est supérieure à celle mesurée au niveau de l'extrémité libre du ressort (48), par laquelle le ressort (37) repose au fond (25) de la rainure de guidage (16).

Abstract: A technique and apparatus for providing reciprocating hydroenhancement includes a pair of fabric spools with a hydroenhancement process disposed therebetween. The hydroenhancement process is configured to impart a minimal amount of hydroenhancement to the fabric passing therethrough and may comprise only a single vacuum roll and associated single hydroenhance- ment jet (other arrangements may use two or three of vacuum rolls and jets in order to provide controllable "front side" and "back side" treatments on a per pass basis). The fabric to be treated is loaded onto a first spool, passes through the hydroenhancement process and is thereafter taken up on the second spool. Once the entire length of fabric has been treated and loaded onto the second spool the process is reversed; the fabric is unwound from the second spool, treated a second time and re-loaded onto the first spool. The process is reversed once again, and a second "forward" treatment is imparted to the fabric. This "back and forth" (i.e., "reciprocating") hydroenhancement process is continued until the desired degree of hydroenhancement has been achieved. Measuring units (such as a permeability measuring system) may be used to evaluate the hydroenhancement on each pass to control various process parameters, as well as to determine when to stop the process.

Title: Bonding fibrous batts with thermosetting fiber-binders of certain epoxy resins
Inventor: BUCK GEORGE S
IPC: C09J163/00
Filed: 1996-07-08
Granted: 2007-05-15
Abstract: A process is described for producing a bonded, non-woven fibrous batt by the use of a dry, solid, particulate, latent-cross--linkable, thermosetting, fiber-binder. This fiber-binder is an intimate mixture of a solid epoxy resin and a cross-linking agent. The epoxy resin has (a) terminal epoxy groups; (b) an epoxide equivalent weight of above about 500; (c) a glass transition temperature above about 40 .degree.C; and (d) a melting point above about 70 .degree.C. In the process the fiber--binder contacts the fibers to form a raw batt with the fiber-binder loosely adhering to the fibers of the batt. Then the raw batt is heated to a cross-linking temperature above the melting point of the fiber-binder but below the scorching or melting point of the fibers thereby melting the fiber-binder. The fiber--binder flows to intersections of the fibers and subsequently reacts the cross-linking agent with the terminal epoxy groups of the epoxy resin. This converts the raw batt into a hot cross-linked batt. The hot cross-linked batt is then cooled to room temperature. Batts are also described as is a process for hot molding these batts.

Abstract: Apparatus and method are disclosed by which a distal end portion of a wire may be deposited at selected sites in body passageways. The apparatus includes an elongate wire having a distal end section for detachment and delivery to a target location, the wire also having a discontinuity located rearwardly of the distal end section for rupturing when vibrational energy is applied to the wire. Also included is a vibrational energy source couplable to the proximal end of the wire for selectively applying vibrational energy to the wire to travel to the discontinuity and cause detachment of the end section. The discontinuities may take the form of cuts formed in the wire, reduced diameter sections in the wire, adhesive, welded or soldered couplings between the wire and the distal end section, or the wire transitioning from the wire to a large mass disposed on the distal end section.

Title: Producing laser light of different wavelengths
Inventor: SAHLEN OLOF
IPC: H04B10/43
Filed: 1997-09-02
Granted: 2010-02-02
Abstract: In a tunable laser device a plurality of basically identical lasers are arranged adjacent to each other in a line or row on a common substrate. The lasers can be DFB--type and they have different emission wavelengths, obtained from e.g. different pitches of gratings which define the wavelengths of the respective lasers. The lasers can be activated to emit light independently of each other by supplying electrical current to contacts located on the top sides of the lasers. When a laser is activated, the other lasers are biased, so that lasers located at one side of the active laser will be transparent to the emitted light, which can then travel from the lasers through an electrooptic modulator, and the lasers located at the other side will absorb the light. By controlling the temperature, the wavelength of emitted light can be finely adjusted. Such a laser device has a compact structure, is fairly insensitive to variations of the used drive currents and can in a simple way be adjusted to different operating conditions and be compensated for aging effects.

Abstract: In a WDM optical transmission system employing optical amplifiers in its transmission path, a supervisory signal channel, used for monitoring and controlling the operation of the amplifiers and spectrally separated from the data transmission, may be multiplexed with the data. A construction of amplifier is disclosed which is capable of being upgraded with an upgrade of the transmission system to include additional data handling capacity, for instance data transmission in an additional waveband and/or in the opposite direction, without interruption of the pre-upgrade data transmission path through the amplifiers. This is accomplished by the use of channel dropping and insertion filters disposed so that the amplifying data transmission path extends via the drop/insertion channel of those filters.

Abstract: Bags for produce or the like are prepared by advancing a thermoplastic sheet and a mesh sheet, each having an upper edge, along a process line. The plastic sheet has a bottom portion which is folded to define a lower edge of the thermoplastic sheet at a fold line. One seals the folded portion of the solid-wall thermoplastic sheet to a lower edge of the mesh sheet. Transverse slits are then formed in the sheets, and the sheets are heat sealed together near edges of the slits to form separate bags between the slits. The slits extend across both lower edges of the bags, but are preferably spaced from the upper edges. One drops produce between the sheet upper edges into the bags, and the bags are then heat sealed adjacent to the upper edges thereof, and subsequently separated by cutting. A novel heat seal die is also shown.
