Abstract: STEEL CONVERSION METHOD                 ABSTRACT OF THE DISCLOSURE     A steel conversion method includes the steps of deliver-ing a first quantity of oxygen and a surrounding sheath of hydro-carbon shielding fluid beneath the level of a quantity of molten ferrous metal or bath contained in a vessel by means of bottom tuyeres and simultaneously delivering a second quantity of oxygen to the bath from above through a top lance.  The oxygen delivered through the bottom tuyeres is sufficient to promote mixing and is about 10% to 40% of the oxygen required for oxidation of impuri-ties with the balance delivered through the top lance.  An addi-tional quantity of oxygen is delivered through the top lance to the space above the bath for post-combustion of off-gases to increase the thermal energy in the bath.  Fluxes such as lime are added from above in lump form in the conventional manner or are entrained in the upper oxygen stream as required.  As the level of carbon in the bath falls toward desired levels, an inert gas is introduced through the bottom tuyeres at an increased rate while the proportion of oxygen is decreased.

Abstract: ABSTRACT OF THE DISCLOSURE    A vital timer for energizing a vital relay at the end of a preselected time interval generated by a vitally programmed microprocessor.  Diverse time data words of the preselected time interval are generated, loaded into diverse registers within the microprocessor, and are incremented by means of a program loop for the duration of the time interval determined by the magnitude of the diverse time data words.  The microprocessor includes checking routines for verifying that the selected time interval has correctly been read, that a microprocessor primary clock bears a predetermined relationship to an external auxiliary clock, and that the diverse registers maintain a predetermined count relationship for the duration of the preselected time interval.  Checking routines produce plural predetermined checkwords indicative of vital timer performance, which checkwords are utilized to address an output program formed of groups of instructions each corresponding to a respective checkword, and each of which must be accessed in a predetermined sequence in order to produce a predetermined time varying output to the tuned vital relay driver.  Thus, the tuned vital relay driver is activated only in the event that each prescribed checkword is generated to verify failure free timer performance. lll/rc

Abstract: Abstract A low frequency tone detector filters out undesired frequencies in a received signal, then a latching circuit locks on when a given number of low frequency cycles are detected, having at least a predetermined peak amplitude. Thereafter, only a second given number of missing or low amplitude cycles will reset the latch.  When the detector determines that the received signal is weak or of very poor quality, false detect signals are essentially prevented.  The circuit is particularly suited to use with AM stereophonic signals where a low frequency tone is added to the difference channel for providing mono/stereo indication and mode switching.

Abstract: MICROBENDING OF OPTICAL FIBERS  FOR REMOTE FORCE MEASUREMENT                 ABSTRACT OF THE DISCLOSURE      A system for remote measurement of structural forces  includes  a plurality of microbend  transduc-ers mounted along the length of the structure for micro-bending  an optical  fiber  in response to structural forces, such as stress acting upon an oil or gas pipeline or  the like.   An optical  time domain reflectometer (OTDR) has a light source for launching a pulsed optical signal for passage through the fiber and a photodetector for sensing as a function of time the intensity of backscattered  light  reflected  back  through  the  fiber, wherein this sensed time function is correlated directly with discrete longitudinal positions along the length of the fiber and the structure.   When one or more of the microbend transducers is activated to induce a microbend in the fiber in response to localized forces acting upon the structure, a portion of the backscattered light is lost at the microbend.  This attenuation in backscattered light intensity is sensed quantitatively and positionally identified by the photodetector.  Specific preferred constructions  for  microbend  transducers  and  system arrangements particularly adapted for detecting structur-al strain in an oil or gas pipeline are disclosed.
