Abstract: ABSTRACT OF THE DISCLOSURE     Optical filters, e.g.  for reflecting infrared radiation while passing visible light radiation    made by applying to the silver reflective coating a protective coating of a metal oxide by magnetron cathode sputtering and only thereafter is the non-reflec-tive layer applied by magnetron cathode sputtering.  The protective coating-oxygen partial pressure and coating rate are substantially less than the non-reflective coating-oxygen partial pressure and coating rate.  Apparently the protective coating prevents damage to the reflective coating.

Abstract: ELECTRONICS FOR FIBER OPTIC VORTEX SHEDDING FLOW METER              ABSTRACT OF THE DISCLOSURE               An optical sensor arrangement comprises a light-emitting diode which is connected to a light detector over a light connection such as a fiber optics fiber.  The fiber may be provided in the vicinity of a vortex shedding flow meter and is bent by the passage of vortices past the fiber.  Bending the fiber causes attenuation of the light signal from the light-emitting diode to the light detector.  The light-emitting diode is powered by a pulse generator which supplies the diode with low duty cycle high-current pulses.  The resulting detected pulses are amplified, sampled and held to obtain peak values for each pulse.  The detected pulse is suppressed by a feedback circuit portion which is activated only after each low duty cycle high current pulse.  The detected peaks are utilized to generate a square wave which is used as a measurement of the variable, in particular the passage of vortices in a vortex shedding flow meter.

Abstract: ABSTRACT      Improved masking apparatus and methods for bulk charging a flowable material into selected cell ends exposed at an end face of a honeycomb structure.  The masking apparatus utilize protrusions which assist in properly aligning the apparatus to the end face and reduce the possibility of improperly charging cells.  In one apparatus embodiment, a planar body is provided having a plurality of hollow protrusions which extend into selected cell ends when the planar body is fitted against an end face of the structure.  A flowable material charged against the planar body passes through the hollow protrusions into the selected cell ends.  In another embodiment, a plurality of preformed protrusions or plugs are mounted along thin, flexible members at predetermined locations.  The plugs are inserted into and block or cover the ends of an equal plurality of cells.  A flowable material charged against the end face passes into the remaining, uncovered cells. The invention is of particular use in fabricating solid particulate filter bodies from ceramic-based honeycomb structures.     Preferably the mask is made of a flexible material, for instance a polymer, preferably an elastomer.  Also described are apparatus and dies for making the die.     Furthermore, a method of aligning the flexible mask with a honeycomb body by vibration is described.
