Title: Cascaded optical multiplexing devices
Inventor: SPOCK DEREK ERSKINE
IPC: H04J14/02
Filed: 1998-05-25
Abstract: An optical multiplexing device is provided comprising multiple wavelength division multiplexers cascaded together. A first one of the wavelength division multiplexers has a common port and multiple optical ports which are optically coupled to the common port. The common port may be optically coupled to a trunk line of a system employing wavelength division multiplexing, for example, a fiber-optic telecommunication system employing 4. 8, 16 or other number of multiplexed channels. The optical ports include multiple channel ports, each of which is transparent to a corresponding wavelength sub-range and reflective of other wavelengths. Thesecond wavelength division multiplexer has a common port optically coupled to one of the optical ports of the first wavelength division multiplexer. The second wavelength division multiplexer also has multiple optical ports which are optically coupled to its common port and include multiple wavelength-selective channel ports. A waveguide, such as a fiber-optic line, can optically connect the common port of the second wavelength division multiplexer to an optical port of the first wavelength division multiplexer. The cascaded WDMs each may be optically coupled to the output of a passive coupler and a housing may be provided defining an enclosed space in which the optical multiplexing device is mounted. Optionally, additional WDMs may be cascaded with the first two WDMs in a parallel or branched formation, an in-lineformation or some combination. Preferably, the channels are interleaved, such that they are removed from the multiplexed signal in certain non-sequential order. The optical multiplexing device also may employ compound interleaving wherein adjacent channels are multiplexed by different ones of the cascaded WDMs. The optical multiplexing devices can operate to add signals, remove signals or a combination of both.

Abstract: When in operation, devices for telecommunications installed in rooms generate a considerable amount of heat. This takes place continuously, and a maximum temperature must not be exceeded. In order to obtain reserve time for an air cooling system having a reserve time system with a guaranteed low temperature level of the liquid for the reserve time system, an evaporator (2) for the air cooling system is provided with a liquid circuit (2b) which is connected with a liquid tank (7). Liquid is circulated continuously through the evaporator with the liquid circuit, where it is cooled by the cooling medium for the air cooling system, at the same time as the inside air is cooled by the same evaporator. The continuous cooling and circulation of the liquid in the tank ensures that there is always the coldest possible liquid available when the ordinary cooling system is not working. In case of failure of the air cooling system, liquid is circulated by means of a liquid pump (6) from the tank via the evaporator provided with the liquid circuit, thus cooling the warm inside air. The heated liquid is returned to the tank. When the air cooling system is working again, it will start to fill the tank with cold liquid.

Title: Layer interference orientation for high temperature gasket
Inventor: SCHWEIGER DAVID J
IPC: F16J15/08
Filed: 1998-09-02
Abstract: A high temperature gasket assembly comprises a plurality of identical symmetrically shaped plates with holes offset from a centerline of each plate. The plates are rotated or flipped into an orientation with the outer periphery of each plate in alignment and the holes in a first plate are skewed with respect to mating holes in a second plate. As a result, a portion of an inner periphery of each hole is in facing relation with an inner face of the other plate. The resulting aperture defines an interference orientation with a diameter greater than a minor thread diameter and less than a major thread diameter of a mating fastener. Thus, the fastener is retained within the aperture without undesirable separation.

Abstract: A horizontal vacuum extrusion line includes a fixed bulkhead (23), a die (24) inside the bulkhead, a telescoping vacuum chamber section (27) and a fixed chamber section (28, 29). A dam (33) in the fixed section forms a pond (72) for immersion cooling of the extrudate. A truss (35) extends from the dam to the bulkhead supporting, shaping and calibration equipment and extends through the telescoping section. Fluid pressurizable seals at each end of the telescoping section are operable after the telescoping section is closed against the bulkhead and the telescoping and fixed sections are locked together. The telescoping section provides a more compact line and easier access to the complex equipment downstream of the die. The extrudate from the die passes down into the pond (72) and then through an orifice (74) in a hood (75) projecting from the chamber into a lower level portion of the pond (78) exposed to atmosphere. The hood also includes a tractor drive (88) to push the extrudate through the underwater orifice. The hood and its contents are accessible through the atmospheric pond. A tractor haul-off and the tractor drive in the hood are the only extrudate drives between the calibration equipment and atmosphere. The higher level of the pond (72) within the chamber downstream of the dam is controlled by a valve in turn controlling the output of a pump. The valve control senses the pond level and operates independently of the vacuum controls.
