Patent CA-2024128-A1 (CA)
Inventor: KELLER RICHARD F
IPC: B05B7/10
Filed: 1990-08-28
Abstract: ABSTRACT      A distinctive method and apparatus for forming a substantially continuous filament of a thermoplastic work material and for imparting a swirling motion thereto comprises a body member which has a work material supply passage and a gas supply passage formed therein.  An outlet nozzle section connects to the body member and has a substantially conically tapered shape.  The nozzle section has a nozzle extrusion passage formed therein in communication with the work material supply passage.  A housing member operably connects to the body member to delimit a substantially annular gas transfer zone in fluid communication with the gas supply passage and to delimit a substantially annular gas outlet passage around the nozzle section. The housing member includes an exit section having inner wall surfaces which substantially parallel the conically tapered shape of the nozzle section.  The inner wall surfaces are in a selected spaced relation from the nozzle section to define the gas outlet passage. The housing exit section and the nozzle section are configured to provide for a selected gas flow which imparts the filament swirling motion substantially without disintegrating the filament, the apparatus thereby constructed to deposit a substantially continuous, swirled filament of the work material onto a selected substrate.

Title: Smokeless pyrolysis furnace with micro-ramped temperature controlled by water-spray
Inventor: KOPTIS ROBERT A
IPC: C10B53/00
Filed: 1991-03-18
Abstract: SMOKELESS PYROLYSIS FURNACE WITH MICRO-RAMPED TEMPERATURE                 CONTROLLED BY WATER-SPRAY                  ABSTRACT OF THE DISCLOSURE A batch-type pyrolysis furnace burns a load of organ-ic combustibles on metal parts without a significant risk of explosion because of a combination of two necessary conditions: (a) a primary water spray is maintained during a large portion of the burn cycle while the main burner is neither turned off nor attenuated until a major portion of the load is combusted; and, (b) the temperature in the main chamber is controlled by a "micro-ramped" programmable temperature controller (PC). By setting the ramp for micro-steps of no more than 2°F per minute, and actuating the primary water spray to maintain the set-point temperature while it is ramped upward, the criticality of the location for the single thermocouple is obviated, and it is unneces-sary to measure the temperature in the throat. The micro-steps eliminate soak periods during the ramp. The main "burn" progresses during the ramp, and at the upper set-point of the ramp (say 800°) with normal fuel supply to the main burner ("high-fire"). The final portion of the burn is completed with the main burner being starved of fuel("low-fire"). The set-point is maintained within the specified narrow range during the main burn with the primary water spray. If the temperature deviates beyond a specified high-er temperature (say by 10°F) a secondary water spray is actuated by the PC. An afterburner burns volatiles gener-ated in the furnace's main chamber. The effluent from the exhaust stack is essentially free of smoke. No catalyst or catalytic device is used to purify the smoke. The main chamber TC and interactive PC thus maintain a fire under controlled temperature conditions in the main chamber with-out an explosion.

Title: Process for producing dimethyl carbonate
Inventor: DI MUZIO NICOLA
IPC: C07C68/00
Filed: 1991-06-03
Abstract: Dimethyl carbonate is prepared by means of a continuous process: * by feeding, to a reaction chamber, methanol, carbon monoxide and oxygen, to a liquid reaction mixture with substantially constant composition and volume, containing methanol, dimethyl carbonate, water, and a copper catalyst; * vapourising from the reaction mixture a stream of methanol, water and dimethyl carbonate, which is developed together with the carbonmonoxide-containing gas stream; and * recovering water and dimethyl carbonate from said vapourised mixture, in amounts substantially equal to the respective amounts thereof which are formed in the reaction chamber and recycling the other components. The process, which is essentially characterized in that in the liquid reaction mixture a methanol concentration and a water concentration are maintained which are respectively equal to, or higher than, 30% by weight, and equal to, or lower than, 10% by weight, makes it possible dimethyl carbonate to be obtained with an improved productivity.

Title: Apparatus and method for inspecting optical fibers
Inventor: KANEKO SHIGEKI
IPC: G01M11/02
Filed: 1991-07-24
Abstract: ABSTRACT OF THE DISCLOSURE        An optical pulse of a fixed width is applied to an optical fiber, back scattering light from the optical fiber is converted to an electric signal, which is converted to a digital signal by sampling with a fixed period.  In a difference calculating section an average of digital signals at a first sample point and at W sample points preceding the first sample point is used as data at the first sample point, and an average of digital signals at a second sample point and at W sample points following the second sample point, which is after the first sample point by a number of sample points corresponding to the width of the optical pulse, is used as data at the second sample point.  The difference between the data at the first sample point and the data at the second sample point is calculated for each of a series of sample points to obtain difference waveform data.  Changing points of the difference waveform data are detected and a spliced point of the optical fiber is decided, based on the detected changing points.

Title: Vapor source for vacuum metallizing
Inventor: WILDER HAROLD J
IPC: C23C14/24
Filed: 1991-10-03
Abstract: ABSTRACT         A metal vapor evaporator source is provided that increases productivity of a vacuum plating operation in which it is used by reducing scrap product due to spatter of liquid metal particles from the evaporator to the product, and by reducing spurious metal condensate within the vacuum chamber, the accumulation of which metal condensate is known to increase downtime of the equipment.  The former is accomplished by inhibiting the generating of such particles by increasing the total pressure on the pool of molten metal and by physically intercepting many of the spattered particles that are generated despite the increased pressure.  The latter is accomplished by partially collimating the beam of metal vapor, a result of intercepting and condensing the stray vapor on a radiant-heat shield that is at a temperature above the melting point of the metal.
