Granted: 1978-11-14
Abstract: DISC INTERFACE LOCATION Abstract of the Disclosure A disc storage file includes a multiplicity of closely spaced continuously rotating flexible or floppy discs associated with an accessing assembly for spreading the discs apart at randomly selected positions to accommodate a magnetic head. Apparatus for locating the disc interface (gap) to be accessed includes a pair of offset photocells which are light coupled to the disc gaps.  The light applied to the photocells is guided in offset channels of a shroud and shaped congruent to the photocell surfaces by offset fiber optic shaping arrays.  The offset arrays and associated electronics allow for accurate counting of gaps in the presence of fluctuating disc motion in the axial direction.

Abstract: ABSTRACT        A method for controlling the composition of matte in the operation of a flash smelting furnace wherein Cu- or Ni-grade is estimated for the matte produced in the settler during the tappings from the settler to a converter at the preceding time and at present time by correcting the Cu- or Ni-grade obtained by assaying the matte tapped from the settler and charged into the converter at present time by means of the Cu- or Ni-to be charged into the converter at the preceding time, and when the difference between the estimated and desired Cu- or NI-grades in the matte or the difference between the assayed and deviated beyond a predetermined tapped at that time is deviated beyond a predetermined allowable range, a present air amount of less than the theoretical amount required for correcting the Cu- or Ni-grade for each percentage of said difference by said difference for the matte tapped at that time, adding said calculated new correcting air amount with the preceding corrected air amount calculated similarly in the preced-ing tapping and calculating the difference between an air amount obtained by adding said sum with the air amount proportional to the square of amount of blended feeds being charged at present time and the theoretical air amount required for reacting the blended feeds being charged at that time and for combusting the fuel oil so as to maintain the Cu- or Ni-grade in the matte produced in the settler by using said blended feeds at the desired Cu- or Ni-grade or so as to provide the desired Cu- or Ni-grade in the tapped matte, and the blast air is fed in an amount of said difference to control the Cu- or Ni-grade in the matte produced in the settler or tapped from the setter.

Abstract: ABSTRACT   A method of crushing particles of material in a ball mill comprises feeding a mixture of balls and a charge comprising the particles to be crushed, a solvent and a lubricant  continuously through a ball mill which initially contains balls.   The balls are recovered from the mixture issuing from the mill and are re-introduced into the mill with a fresh charge.   On? form of apparatus for carrying out the method comprises a cylindrical container disposed with its axis horizontal and rotatable about said axis. The inlet and outlet of the mill are arranged centrally at opposite ends of the container, and the outlet leads to an annular sieve which rotates with and is coaxial with container.   The sieve retains the balls for return to the inlet and allows the milled charge to fall into a receptacle.   In an alternative form of the apparatus, the container has inlets at both ends and has an outlet with an associated sieve at its mid-length.

Abstract: CENTRIFUGAL COMPRESSOR WITH INDEXED INDUCER SECTION AND PADS FOR DAMPING VIBRATIONS THEREIN                   Abstract of the Disclosure A centrifugal compressor assembly for a gas turbine engine includes an inducer section and an impeller section mounted for rotation about an axis.  Because leading edges of the impeller blades are cambered, damper pads, extending perpendicular to the low pressure sides thereof also extend axially forward.  Blades of the inducer section are indexed rotationally rearward of the impeller blades to improve the distribution of compression gases through the impeller section and high pressure surfaces of the inducer blades mate near their leading edges with outward sur-faces of the damper pads.  Because the pads and inducer blades vibrate at different frequencies, inducer blade vibrations that might otherwise cause fatigue are attenuated by contact with the damper pads.  The damper pad arrangement thus permits the damping of vibrations in the inducer blades notwithstanding the indexed relationship between the inducer section and the impeller section.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to diffuser drapes and has a particular application to drapes such as those used in surgical operations.  Diffuser drapes have been proposed with a substantially elliptical aperture defining a work area which is surrounded by an inflatable clean air duct means integral with the drape.  The clean air duct means has a diffuser therein surrounding the aperture and shaped so diffuse low velocity clean air radially through the diffuser inwardly across the aperture from opposite sides thereof to provide a resultant flow away from the aperture and upwardly and partly outwardly of the work area about the upper edges thereof.  One of the prob-lems faced with this type of drape is that of manufacturing the diffuser in an economical fashion.  In the present invention the diffuser comprises an upper diffuser part and a bottom diffuser part joined by a seam adjacent the periphery of the work area, the bottom diffuser part having an effective area of between approximately 50% less than and approximately 20% greater than the said work urea.  The top diffuser part has an annular width of approximately 3 inches and an area sufficient to provide a class 100 clean station air flow pattern adjacent the work area.

Abstract: ABSTRACT OF THE DISCLOSURE           An engine analyzer in which testing apparatus is con-trolled in accordance with a signal generated from voltage pulses applied to the spark plugs, the signal being converted into a square wave voltage of a frequency corresponding to the frequen-cy of occurrence of the ignition voltage pulses.  Specifically, this is accomplished by producing a first square wave voltage of one-half the frequency of occurrence of the pulses, integrating this square wave voltage to form a first triangular wave voltage of the same frequency, inverting portions of this first triangu-lar wave voltage to form a triangular wave voltage of the same frequency as the frequency of occurrence of the pulses and dif-ferentiating this further triangular wave voltage to form a square wave voltage of the frequency of occurrence of the pulses.  The testing effect is initiated at the end of each first half cycle of the final square voltage so that the testing operation is in-itiated at a time intermediate the times at which successive vol-tage pulses occur.

Abstract: ABSTRACT           The invention provides a method of, and a device for, coupling together substrates, for example tubular articles, which device includes an inner member, having disposed thereon a fusible material for binding the substrates together, and an outer member.  The substrates to be joined are inserted between the fusible material and outer member and the resulting assembly is heated.  The application of heat is maintained until it permeates the assembly and raises the temperature of the fusible material enough that it melts and flows through and/or about the substrates to be joined. The inner and outer members act to confine the melted fusible material by defining boundaries between which it can flow.  Longitudinal flow of the material can be controlled by limiting the area heated, by the configuration of the coupling members or substrates, or by providing the coupling with additional members that limit longitudinal flow.  When the heating is discontinued, the fusible material hardens to bind the substrates together.  Either the inner member, outer member, or both  may be a heat recoverable or spring member to provide compressive forces in the area of the joint being formed to facilitate the flow of the fusible material.
