5483040 ELECTRICALLY HEATED HOT GAS SOLDERING INSTRUMENT
-61 degrees C is passed through indirect cooling coils in a cold store which it leaves at -45 degrees C. This air is then passed through the plate-fin heat exchanger before being recycled to the compressor. The refrigeration delivered is about 1.05 kw refiigerationikw power input.
Fortune William S Malibu, CA, UNITED STATES An electric soldering iron is disclosed in which a gas such as compressed air is electrically heated and then forced through a metallic soldering tip which is deeply slotted or finned for maximum heat transfer thereto. Soldering is then accomplished by applying the thusly heated tip to the workpiece. The slots may be formed to exhaust the hot gas forwardly over the tip to add heat to the workpiece and control the gaseous environment thereof; or the slots may be formed to exhaust the hot gas laterally or rearwardly to help in removing pollutants from the operator’s environment.
5483127 VARIABLE ARC ELECTRONIC BALLAST WITH CONTINUOUS CATHODE HEATING Widmayer Don; Chiu Alex W Bethesda, MD, UNITED STATES assigned to Don Widmayer 8z Associates Inc A fluorescent lighting control system providing automatic and/or manual adjustability of the arc current(s) in one or more fluorescent lamps to permit operation of the lamps at less than rated wattage, and its concomitant luminous flux, in interior building spaces where full light output of the installed lamp(s) is rarely required particularly when daylight components are present. The goal(s) of this invention is to provide means to reduce wasteful electrical consumption in buildings and thereby reduce operating costs and gain the attendant benefit of dampening the increasing need for more electrical generation with its concomitant environmental pollution problem.
5484582 PROCESSFOR AMMONIA RECOVERY IN AMMONIA PRODUCTION Lee Jing M Stafford, TX, UNITED STATES A process and unit for the recovery of ammonia in ammonia production are disclosed. All or a portion of a high pressure liquid ammonia product stream is introduced into a syngas makeup stream to produce a mixed vapor-liquid refrigeration medium for condensing ammonia from a synthesis loop product stream. Following the product stream ammonia condensation step, the vapor component of the mixed vapor-liquid stream is compressed and cooled for condensing ammonia therefrom. Liquid ammonia separated from the low pressure mixed vapor-liquid stream can be withdrawn as a low pressure liquid ammonia product. An ammonia-lean makeup gas is then combined with the ammonia-containing product recycle gas stream from the synthesis loop and further compressed. The process preferably includes recycle of all or a portion of the low pressure liquid ammonia product as a supplemental refrigerant. A high pressure, ammonia-lean syngas vapor stream obtained following separation of the high pressure ammonia condensate can be used as a process cooling medium for chilling the syngas makeup stream and syngas stream. In such a manner, both ammonia and syngas compression can be consolidated in a single syngas compressor and the use of an ammonia refrigeration compressor can be eliminated.
