Abstract: METHOD OF MAKING AN ARTICLE COMPRISING AN OPTO-ELECTRONIC    DEVICE AND AN OPTICAL WAVEGUIDE COUPLED THERETO          Abstract A method for aligning an opto-electronic device such as a semiconductor laser to a waveguide on a substrate is disclosed. The method comprises placing the device onto the substrate such that it is in rough alignment with the waveguide, optically pumping the device such that the device emits electromagnetic radiation, with some of the emitted radiation being coupled into the waveguide and detected by appropriaee means. If indicated by the detector signal, the position of the device is then adjusted until the desired degree of coupling is attained, whereupon the device is mechanically secured to the substrate and appropriate electrical connections made between device and substrate. Devices useful in the practice of the method typically comprise a window in their top metallization layer.

Abstract: WATER HEATER CONSTRUCTION AND METHOD OF MAKING SAME               ABSTRACT      A water heater construction including an inner tank for containing water surrounded in spaced apart relationship by an outer shell.  A sleeve of insulation material, such as fiberglass mat is located in the annular space between the inner tank and outer sleeve and extends from proximate the bottom end of the water heater construction upwardly longitudinally thereof a distance less than the entire height of the water heater construction such that the top edge of the insulation sleeve is a distance below the top end of the water heater construction.  The top edge of the insulation sleeve includes an annular cuff which is of a radial thickness greater than the radial thickness of the rest of the insulation sleeve such that the cuff is compressed between the interior wall surface of the outer shell and exterior wall surface of the inner tank.  An expanded foam thermal insulation material fills the annular space above the cuff of the insulation mat.  A method of making the water heater construction includes the steps of locating a sleeve of insulation material around the exterior wall surface of the inner tank extending from proximate the bottom end of the inner tank and extending upwardly longitudinally thereof a predetermined distance less than the full length of the inner tank, folding the top end of the insulation sleeve back over itself to form an annular cuff at t' top end of the sleeve, and positioning the outer shell concentrically over the inner tank whereupon the annular cuff is compressed between the interior wall surface of the outer shell and exterior wall surface of the inner tank.  The annular space above the annular cuff of the sleeve is then filled with an expandable foam insulation material which is allowed to foam in situ.

Abstract: ABSTRACT OF THE DISCLOSURE     An embedded modem that does not require a dedicated controller and operates with existing communications software uses the host processor of the computer to interpret new and redefined communications interrupt requests.  In response to an interrupt request, the control of the processor is transferred from the communications software to a driver program stored in the main memory for the processor.  Under the operation of the driver program, the processor interprets control characters and causes the appropriate commands to be carried out in the modem.      Once these commands have been processed, the control of the processor reverts back to the communications program.  The processor thereby functions as a virtual controller that is interpreted to be an external controller by the communications program.

Abstract: In  the  method  of  ultrasonic  transit-time measurement in liquid or solid materials by the pulse-reflection method,  a test head transmits a pulse,  if possible in the form of a shock wave, which travels through a buffer zone and partly enters the test piece and is partly reflected from its surface.  The entry or back-wall echo reflected from the surface into the test head (the starting echo) is used to derive an echo-start signal for starting a transit-time measurement (echo-start), which is stopped by a subsequent back-wall echo (useful signal provided its amplitude exceeds an  adjustable threshold value.   The height of the threshold value in connection with the echo-start signal is progressively altered in dependence on the amplitude and variation in time of the starting echo; the threshold value initially has a high value during a first, adjustable-height threshold and then decreases along a slope,  in accordance with a preset function and within an adjustable time,  to a second threshold, which is also adjustable in height.
