Abstract: A tunable optical filter is configured to take point measurements at a few optical frequencies per frequency channel of a DWDM optical network. The measurement frequencies are shifted by pre-determined amounts relative to the optical frequency channel being characterized. Since the spectral shape of the tunable optical filter is known, the center optical frequency, the modulation bandwidth, and the total optical power of the channel can be obtained from as few as three optical measurements. The center optical frequency and the total optical power can be continuously monitored by providing a tunable filter stage coupled to an interleaver stage, and computing a ratio and a weighted sum the optical signals at the two outputs of the interleaver stage.

Abstract: The energy of a series of output pulses of a solid state laser pumped by a diode array and triggered by a Q-switch is stabilized and rendered independent of the repetition rate by interrupting the pumping to allow the energy stored in the laser active element to fall at the commencement of an interval between a pair of Q-switch trigger signals that is longer than the interval corresponding to the chosen repetition rate. Before the second of this pair of Q-switch trigger signals occurs, the pumping is recommenced for a duration and at an input level that restore the stored energy to the value required for generating output pulses of the laser at the desired energy level.

Abstract: An in-line microwave applicator has an electromagnetic energy wave generating unit which transmits waves, particularly microwaves, dispersing from a longitudinal axis. The dispersing waves are interrupted by microwave diverters which cause the wave lengths to be transmitted through holes from the first chamber to a second surrounding chamber. The second surrounding chamber has interior walls which are reflective to the microwaves and may have a spiral rib to enhance reflectivity. Product for heating is passed through the second chamber to be irradiated by microwaves exiting the holes from the first chamber. The holes are generally elongate in shape and can be surrounded with microwave transparent material to prevent material from falling through. The microwave diverters can be protrusions extending from the holes into the inner chamber by increasing amounts as the distance from the microwave energy generating unit increases. Alternatively, cones placed at varying angles, a generally spiral shape member, or a series of disks can be used as microwave diverters. Product can be carried through the second chamber using a single or variable pitch helix or screw.

Abstract: A dryer assembly dries waste materials to a predetermined moisture level. The dryer includes a drum having an inlet where waste materials and hot gasses are simultaneously introduced, and an outlet where dried materials and hot vapors are transferred out of the dryer. The drum presents a plurality of preheat baffles in which the material is heated by but does not contact the gasses, thereby avoiding premature combustion of the material. Baffle sections located downstream of preheat baffles uniformly distribute material downstream into a primary drying section of the drum, where the material is mixed with the gasses to uniformly dry the material to the predetermined moisture level. The primary drying section includes alternating baffle sections which dry the material and which recycle material that is not yet dried back into the preceding baffle sections, respectively. The dryer can be readily adapted to accommodate a wide variety of materials of widely varying moisture levels by modifying the dwell times of the material within individual dryer sections and/or by varying the diameter of the dryer and the lengths of the individual dryer sections.

Abstract: Waste materials are efficiently and completely incinerated in a gasification unit with a minimum amount of fly ash while ensuring complete sterilization of residual materials. The gasification unit includes a refractory liner which is stepped to define primary, secondary, and tertiary combustion chambers where waste materials are completely incinerated. A fan is adapted to draw combustion air past the outer surface of the refractory liner to initially heat the combustion air while simultaneously cooling the refractory liner. The fan is further adapted to force combustion air under pressure into a preheating chamber in which the combustion air is preheated before passing into the primary and secondary combustion chambers. Turbulence in the combustion chambers, brought about through equalization of air pressure in the preheating chamber, is effected through the provision of tangential air inlets in the walls of the refractory liner. A sloped floor of the refractory liner cooperates with an ash removal device and a secondary burner to ensure complete combustion of the waste materials and sterilization of residual ashes within the gasification unit.

Abstract: A waste treatment system conditions waste materials for combustion by uniformly drying them to a predetermined moisture level and subsequently incinerating the dried materials in a burner which effects complete combustion of even high moisture content fuels. The system includes the burner, a dryer assembly, and a system of fans which clarifies vapors withdrawn from the dryer and which returns at least part of these vapors to the burner. The system mixes exhaust gasses from the burner and recycled vapors returned by the fans to produce gasses of a suitable temperature for drying the materials. The waste materials and the gasses are then introduced into the dryer, which is designed to use the gasses to dry the material uniformly to the predetermined moisture level without burning them prematurely. The dried materials are then conveyed to the burner, where they are burned to produce more exhaust gasses for drying additional materials. The residual ash in the burners is nontoxic and is suitable for burying. The system can be readily adapted to dry and burn a wide variety of materials by modifying the dwell times of the materials within the individual dryer sections, and/or by changing the dimensions of the dryer.
