摘要： The invention is directed to a dispersion compensation module of extremely simple design that does not rely on a spool-and-hub or similar device for holding the optical fiber used in the module, such module being here termed a “Free-Fiber dispersion compensation module”. In the inventive dispersion compensation module the optical fiber therein is in a relaxed coiled configuration having minimal tension. It has also been discovered that while coil tension is relieved by removing it from the winding spool prior to placing it in the dispersion compensation module, the tension can be further relieved by coating the coiled fiber with a finely powdered substance which will not react with or otherwise harm or damage wither the fiber or the module containing it, for example, talcum powder.

摘要： A component holder has a base and a component holding block extending upward from the base. The component holding block includes a pair of walls, the walls defining between them a channel dimensioned to closely receive an optical component cradled in a resiliently compliant member, such as a pad or a shaped component. An optical component is loaded into the channel by placing the optical component and a resiliently compliant member over the channel and wedging the optical component and the resiliently compliant member into the channel such that the optical component is cradled inside of the resiliently compliant member and such that the optical component and the resiliently compliant member are held in position in the channel by friction.

摘要： A gravity assisted anti-reverse rotation device for preventing reverse rotation of pumps and the like.A horizontally mounted pawl is disposed to mesh with a fixed ratchet preventing reverse rotation when the pawl is advanced into intercourse with the ratchet by a vertically mounted lever having a lumped mass. Gravitation action on the lumped mass urges the pawl into mesh with the ratchet, while centrifugal force on the lumped mass during forward, allowed rotation retracts the pawl away from the ratchet.

摘要： The pump isolation valve provides a means by which the pump may be selectively isolated from the remainder of the coolant system while being compatible with the internal hydraulic arrangement of the pump during normal operation of the pump. The valve comprises a valve cylinder disposed around the pump and adjacent to the last pump diffuser with a turning vane attached to the lower end of the valve cylinder in a manner so as to hydraulically match with the discharge diffuser. The valve cylinder is connected to a drive means for sliding the valve cylinder relative to the diffuser support cylinder so as to block flow in either direction through the discharge diffuser when the valve is in the closed position and to aid in the flow of the coolant from the discharge diffuser by means of the turning vane when the valve is in the open position.

The heat sink is substantially parallel to the printed circuit board and is separated from the printed circuit board by spacers. The pump laser is connected to one side of the heat sink, which has a plurality of fins on an opposite side from where the pump laser is connected. The first half plug-in member of the optical connector and the second half plug-in member of the electrical connector are each secured to the printed circuit board and are located at an insertion end of the pump laser card assembly. The reel is disposed between the printed circuit board and the heat sink and the optical fiber wrapped around the reel has a first end connected to the pump laser and a second end connected to the first half plug-in member of the optical connector. The detachable plug-in pump laser card assembly is plugged into a port located on a base plate of the optical fiber amplifier, where the first half plug-in member of the optical connector optically engages with a mating member and where the second half plug-in member of the electrical connector electrically engages with a mating member.

摘要： An improved heater facsimile temperature detector (47) has an increased dynamic responsiveness in measuring temperature changes. The improved HFTD (47) reduces the amount of mass surrounding the thermocouple tip, thus, reducing the time lag caused by the intervening heating or cooling of this material before the temperature change can affect the thermocouple. The thermocouple (69) is welded to a body (59) extending beyond a machined flat (54) on the outer surface of an intermediate portion (49) of the HFTD. The body does not extend beyond the outer surface (51) of the intermediate portion.
