Abstract: A media filter cabinet for a gas furnace is sized to accept a high-efficiency media filter while being easily adaptable to accept a standard size filter. A perforated duct flange on one side of the cabinet permits ease of installation since the flange can be bent at 90 or 180 degrees along the perforations, or removed, depending on the type of duct the cabinet is installed with. The cabinet is adapted to fit a standard filter by using a removable bracket and a wire to retain the standard filter within the cabinet. With the removal of a front door and a back side of the cabinet, the cabinet collapses to diminish its shipping size. In one embodiment, the cabinet is in kit form which is easily assembled.

Abstract: A laser diode bar is separated into laser diode dice after bonding the laser diode bar to a submount. In one embodiment a GaAs laser diode bar is soldered to a diamond submount with gold—tin solder. The difference in the coefficient of thermal expansion between the submount material and the laser bar material is sufficient to create tensile stress in the laser diode bar and cleave the laser diode bar into dice as the assembly cools from the soldering temperature. Use of an electrically insulating submount material allows the laser diodes to be connected in series. Diamond blanks that are essentially un-metallized submounts are used during assembly to avoid bowing, or “smile”, of the laser diode assembly.

Abstract: A laser package comprises a laser diode source having a first Fabry-Perot cavity between a highly reflective back facet and low reflective front facet for providing a first light output for an optical application. A light monitor is positioned adjacent to the back facet and aligned to receive a second light output from the laser diode back facet. A pigtail fiber having a lensed fiber input end is positioned from the laser diode front facet to form an optical coupling region and is aligned relative to the lasing cavity to receive the first light output into the fiber, the light output exiting the package for coupling to the application. A portion of the first light output from the lasing cavity is reflected off the lensed fiber input end with a portion directed back into the lasing cavity and another portion reflected off of the laser diode front facet.

Abstract: A microlens on the end of an optical fiber has reduced back reflections to a light source, such as a pump laser diode. In a particular embodiment, the microlens is lapped on two radii, at least one of which is offset from the center axis of the fiber, to form a point on the end of the fiber, thus reducing a surface for reflecting light back to the light source. In another embodiment, the microlens is formed with two different side surface angles to accommodate misalignment of the light source to the fiber mount. In another embodiment a Fresnel lens structure on the end of the fiber operates optically as an angled chisel lens.

Abstract: A process is proposed for configuring a product or a product combination on a PC, which can be connected or is connected via a data link with a data processing facility or computer of the product manufacturer. The product or product combination and/or their individual components are portrayed on the display of the PC by means of a configuration program in this computer, menu-guided on the basis of a selectable system concept for the product or product combination, where the dimensioning and working parameters (11, 12) are selected and/or fed in and the individual components required for this are automatically selected from the individual components present in the data bank of the computer and/or automatically configured or adapted. The resulting individual components are represented and/or listed.

Abstract: A fixing station for a printer or copier includes a heating device for fusing toner to the carrier material and a cover that is selectively insertable between the heating element and the carrier material. The cover may be a window blind type cover. Where two sided fixing is provided, both heating devices have a cover. The cover may have an energy storage spring to cause the heating device to be covered in the event of an emergency. An electro-magnetic locking device may be provided to retain the cover in an open position.

Abstract: An optical switch is fabricated on a single substrate and switches planar waveguides into and out of alignment with each other. The switch is constructed by selective deposition and etching of layers that make up the desired waveguides and physical structures of the switch. The physical structures include a movable structure upon which one of the waveguides resides, the movable structure being freed from the substrate by deep etching underneath it. A heat source may be used to provide heat to the movable structure, which causes its thermal expansion and resulting movement of the waveguide on it into or out of alignment with another waveguide. A third waveguide may be located so as to align with the waveguide on the movable structure when it is at an ambient temperature.

Abstract: The apparatus for conveying finely powdered material from a reservoir includes a suction/pressure unit that projects into the reservoir. A gas is introduced into the suction/pressure unit and is mixed with the finely powdered material that is sucked into suction/pressure unit from the reservoir to form a powder/gas mixture and this mixture is discharged. Compressed air blows into the reservoir in a finely dispersed manner to fluidized the finely powdered material so that the extraction of the finely powdered material from the reservoir is facilitated.

Abstract: A process for producing a frictionally locking connection of two structural component parts, especially a shaft and a hub, including plastically deforming a round structural component part into an oval or polygonal shape by applying force, applying additional force to substantially elastically round the oval or polygonal structural component part, assembling the structural component parts while maintaining the additional force, and then cancelling the additional force so that the round structural component part springs back into the oval or polygonal shape whereby the structural component parts are connected with one another by a press fit.

Abstract: Apparatuses and processes for laminating a finish layer of paper, plastics, film, foil, and other thin sheet material to corrugated material along a corrugator line. The finish layers may be single layer or composite material and are preferably, but not necessarily preprinted, reverse printed, etched or otherwise. The finish layers may be produced, supplied and run in any desired width to suit a customer's needs, without the need to engage in the planning, expense and scheduling necessary to run an entire full width roll of preprint material as single face or double face liner on the corrugator, and without the problems inherent in applying graphics to containers or cartons during the conversion process.

Abstract: A switchable DFB (distributed feedback) laser which includes a waveguide layer having an impressed diffraction grating composed of two or more superposed subgratings having different respective grating constants. The diffraction grating is either frequency modulated (FIG. 3a) or amplitude modulated (FIG. 3b) or is a mixed form of these two types of modulation. Each subgrating can be employed to generate an emission wavelength that is a function of the grating period. By changing the temperature or changing the injection current, the effective index of refraction of the laser is changed, thus enabling the setting of an emission wavelength which is a function of the modulated diffraction grating. The switchable DFB laser according to the present invention may be employed for optical data transmission and particularly in narrowband wavelength multiplex operation.

Abstract: A package for the complete and protective enclosure of an article is described in which the article is fully enclosed by a continuous surface of rigid or semi-rigid material so as to form a housing. The housing is banded by a section of sufficiently reduced wall thickness to permit the frangible separation of the housing into two segments which are then drawn apart with the enclosed article being engaged by one of the segments for withdrawal from the other segment. The article can be fully assembled or partially assembled while in the package and means are described in the latter instance for dispensing the fully assembled article automatically in the course of removing it from the package.
