Abstract: ROYCE G. ROBERTS            METHOD AND APPARATUS FOR TALLYING PIPE                  ABSTRACT OF THE DISCLOSURE         Tubular goods, such as drill pipe and production tubing, is measured while going into and coming out of a borehole.  An electronic beam is directed from a transmitter and is detected by a distance measuring receiver.  The beam commences at a known station relative to one end of a pipe suspended in the derrick; and is received at a second station which is indexed respective to the traveling block of the drilling rig.  Another beam measures the 1 position of the other end of the pipe respective to the traveling block.  These measurements enables the length of each stand of pipe to be accurately ascertained while the pipe is held suspended with-in the derrick at a location above the derrick floor.  Electronic circuitry, including a digital instrument, automatically computes the length, displays the length in feet and tenths on a digital readout, records the length on a print-out tape, and incorporates an accumulative memory register. This enables joints or lengths of pipe to be tallied, one after another, and the lengths are auto-matically calculated while accumulative totals are displayed and recordrd.

Abstract: ABSTRACT         A method of producing integrated MOS field effect tran-sistors is provided wherein an additional interconnect consisting of a metal silicide is utilized.  All contacts to the active MOS regions and polysilicon regions for the metal silicide level and for the metal interconnect - silicide mushroom contacts - as well, are opened before the deposition of the metal silicide layer.  In order to achieve an overlapping contact, a layer comprised essenti-ally of a silica-phosphorus glass layer is utilized as an insula-tion layer between the polysilicon level and the silicide level.          This layer is of such a nature as to effect a high selectivity of an etching agent by itself, relative to the thermally generated oxide regions positioned on the substrate, relative to the poly-silicon regions and relative to the substrate, when producing the contact holes.  In preferred embodiments, a HF/NH4F etching mix-ture is utilized as the etching agent.  The method is useful in production of complementary MOS field effect transistor circuits in VLSI technology.

Abstract: EAR PATHOLOGY DIAGNOSIS APPARATUS AND METHOD                 Abstract of the Disclosure A method and apparatus for diagnosing pathologies of the ear, particularly pathologies such as otitis media, directs into the ear canal a sequence of acoustic waves covering a range of frequencies from a few hundred Hz to several kHz and determines the presence or absence of resonance when the incident and reflected waves are combined.  The measurements are made without pressurizing the ear canal and it is not required that the contact between the instrument and the ear be air-tight.  Accordingly, essentially no discomforture of the patient results from use of the instrument.  The requisite measurements are made quickly (of the order of tens of milliseconds) and thus the distorting effects of patient movement are effectively eliminated.  An improved version of the instrument is completely self-contained and hand-held and has the form of a "tee" in which the resonant frequency and amplitude are visually indicated by means of horizontally-and-vertically disposed arrays of light-emitting diodes.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a process for controlling the photocoagulation of biological tissue and to an apparatus for performing the same.  An intense light radiation source and a measuring radiation source is imaged in the area to be coagulated.  On the basis of the information obtained from the local luminance distribution, it is possible by means of a regulating unit acting on the sighting unit and the imaging optics to both select the area and also set the intended coagulation area within the same.  The control of the irradiation takes place by means of a regulating device acting on the intense light source and its imaging optics.  The local luminance distribution is determined from the measurement of the luminances in individual partial areas of the area illuminated by the measuring radiation source.  The invention is based on the findings of recent research showing that the size of the coagulated tissue volume can be determined by measuring the increase in the luminance.  On the basis of this measurement, it is possible to discriminate the radial and depth extension of the coagulation action and this can be used for the planned control of the coagulation process, in a way which is not known with the prior art device and processes.

Abstract: ABSTRACT A continuous, high speed method for elasticizing articles such as disposable diapers, incontinent briefs, and the like by securing an elastically contractible element to a moving, interconnected web of said articles, said elastically contractible element causing the discrete articles cut from the web to shirr in a direction substantially perpendicular to the direction of web travel. Prior to application and securement, the web from which the elastically contractible elements are cut is laterally stretched while at an elevated temperature which is less than its crystalline melting temperature and allowed to cool to ambient temperature. This molecularly orients the elastomeric material and makes the web dimensionally heat unstable parallel to the direction of stretching. The elastically contractible element is cut from the web of the heat unstable elastomeric material so that the length of the element coincides with the width of the heat unstable web. The elastically contractible element is applied to the moving web of interconnected articles while in a substantially untensioned, molecularly oriented, dimensionally heat unstable condition. The elastically contractible element is so oriented when applied to the web of interconnected articles that the direction of lateral stretching applied to the elastomeric web to impart a dimensionally heat unstable condition is aligned substantially perpendicular to the direction of travel of the web of interconnected articles. The discrete articles cut from the web are thereafter subjected to an external stimulus, such as heat, to cause the elastically contractible element to shrink and become dimensionally heat stable and elastic in a direction parallel to its length, thereby imparting shirring in a direction substantially perpendicular to the direction of web travel.

Abstract: CLOSED FCC CYCLONE CATALYST SEPARATION METHOD AND APPARATUS                               ABSTRACT   The present invention involves an improved process and apparatus for the fluid catalytic cracking (FCC) of hydrocarbons. In such an invention, the output of a reactor riser zone is fed to a riser cyclone separator, a primary cyclone separator, and secondary cyclone separators, connected in series within a single reactor vessel.  The riser cyclone separator is connected to the primary cyclone separator by a conduit, which prevents random post-riser thermal cracking of the hydrocarbons after they exit the riser cyclone separator.  The conduit contains an annular port to allow stripping gas to enter the conduit to improve the separation of hydrocarbons from catalyst.  Catalyst separated in the riser cyclone separator can drop through a riser cyclone dipleg and can then pass through a dipleg seal which comprises a seal pot or catalyst held around the dipleg.  The conduit is formed by two overlapping parts, one having a larger diameter than the other to form the annular port and packing or spacers may be used to align and space the overlapping parts.

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for controlling the combustion of natural gas in a natural gas fired appliance is described.  Exhaust gases are sampled and maintained at a predetermined constant temperature between the dew point and the steam point.  The relative humity of the constant temperature gas is monitored by a hygrometer.  Relative humidity deviations from a predetermined value result in output signals from the hygrometer to a control circuit.  The control circuit is connected to regulators in the air intake or chimney of the applicance which regulate air intake to keep the relative humidity substantially constant and hence control combustion of the gas.  In another embodiment the relative humidity of the exhaust gases and the combustion air intake are monitored by separate hygrometers which are linked to each other so that a change in the relative humidity of a gas affecting one hygrometer will compensate the other hygrometer and control combustion as before.  The latter arrangement is useful when the relative humidity of the combustion intake air is very high as occurs in hot, humid summer weather.
