Granted: 1982-02-09
Abstract: ABSTRACT OF THE DISCLOSURE:         Equipment is disclosed for developing high velo-city gas blasts or jets arranged to effect fiber formation from attenuable material, such as molten glass.  Preferably the apparatus makes possible effecting attenuation in two stages, each of which utilizes a pair of high velocity whirling currents or tornadoes, with the gas in the two tornadoes of each pair turning in opposite directions and merging in the downstream  direction, means for supplying the attenuable material being arranged to deliver a stream  of the material into the influ-ence of the tornadoes upstream of the point of confluence.  In the technique disclosed, a gaseous jet is directed transversely into a gaseous blast of larger cross section, thereby developing a zone of interaction of the jet.  Each fiberizing center incorporates a plurality of components including means for generating the jet, means for generating the blast, and means for supplying the stream of attenuable material.  In addition, the fiberizing center may also incorporate an additional structural element or means positioned along the path of the jet and influencing the jet flow.  The disclosed equipment also includes control mechanism providing for shifting or alter-ing the operative interrelation between various of the components at the fiberizing center, for the purpose of compensating for fluctuations in certain operating conditions.

Abstract: ABSTRACT           A tin-free steel sheet having a surface layer of hydrated chromium oxide and an intermediate layer of metallic chromium between the surface layer and the steel base, is produced by pre-treating a degreased steel sheet by subjecting it to an anodic treatment for activating the surface of the steel sheet without forming thereon hydrated chromium oxide, and immediately thereafter to a cathodic treatment for forming a film of hydrated chromium oxide on the steel sheet, each of the anodic and cathodic treatments being carried out at a temperature below 60°C and in an acid electrolyte consisting of at least one chromium compound selected from the group consisting of chromic acid, alkali metal chromates and dichromates, ammonium chromate and dichromate.  The quantity of elec-tricity used is at least 0.25 coulombs/dm2 in the anodic treatment and ranges from 0.25 to 20 coulombs/dm2 in the cathodic treatment such that the hydrated chromium oxide is formed in an amount of 3 to 20 mg/m2 as chromium.  The steel sheet thus pre-treated is thereafter subjected either to an electrolytic chromic acid treatment or to a chromium plating followed by an electrolytic chromic acid treatment so as to farm the aforesaid surface layer of hydrated chromium oxide and intermediate layer of metallic chromium, the hydrated chromium oxide film forming part of the surface layer.  The tin-free steel sheet produced in accordance with the invention has improved lacquer adhesion after aging in hot water and under retort conditions.

Abstract: ABSTRACT OF THE INVENTION A centrifugal clutch assembly having a resilient restrain-ing means for providing a radially inwardly directed restrain-ing bias to each of a plurality of clutch shoe members is disclosed. The restraining means comprises a coiled spring member circumferentially surrounding and in contact with each clutch shoe member and a rod spring member extending substan-tially a complete extent of and enclosed within the coil spring member. A coil spring member and the rod spring member each contribute to the radially inwardly directed bias whereby the idle range of the clutch mechanism is increased over the use of either spring member by itself. In this way, overstressing of a spring member is eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE     A cover for a reservoir of a master cylinder.  The housing of the master cylinder has a plurality of vertical slots located in a flange that surrounds the reservoir.  Each of the vertical slots is connected to a locking surface by a tapered section in the flange.  A diaphragm has a series of tabs which are located in the slots to align expandable sections thereon with the reservoir.  The cover has a lip that surrounds a peripheral ledge.  A series of detents are located in the lip.  The detents are located in the slots in the flange and a horizontal force is thereafter applied to the cover.  The horizontal force moves the detents from the slots through the tapered section to the locking surface to vertically compress the diaphragm between the peripheral ledge and the housing surrounding the reservoir to seal the reservoir from the surrounding environment.

Abstract: ABSTRACT OF THE DISCLOSURE  .        In a railway tank car bottom outlet lading valve as-sembly, an operating handle assembly for the lading valve in-cludes an operating shaft extending vertically within a lading outlet chamber.  The shaft is provided with a non-round shaft tool connection portion near the bottom thereof.  An operating handle is pivotably mounted on the outlet chamber adjacent the non-round connection portion.  The operating handle includes a handle non-round connection portion which engages the shaft non-round connection portion.  A handle-storing bracket for the distal end of the operating handle is mounted upon the tank body ox on an upper mounting flange portion of the outlet chamber adjacent a tank car bottom outlet mounting flange.  The bracket is preferably U-shaped and includes a removable pin extending between opposite arms of the U-shaped bracket.  When the pin is removed from the mounting bracket, the handle may be pivoted to a generally horizontal position to rotate the shaft through engagement of the handle non-round portion with the shaft non-round portion, and thus move the lading valve between open and closed positions. After use, the distal end of the handle may be returned to the stored position in the handle storing bracket with the pin back in place.

Abstract: QUANTITATIVE CHROMATOGRAPHIC ANALYSIS WITHOUT CALIBRATION                 Abstract of the Disclosure A quantitative analysis of the concentration of the individual components in a sample is obtained using a chromatographic analyzer without the need to calibrate the chromatographic analyzer detector.  Two chromatographic analyzer systems are utilized to analyze two identical samples using two different carrier fluids.  The difference  in the  response of the two chromatographic analyzers is proportional to the difference in the properties of the two carrier fluids being measured by the chromatographic analyzer detectors and the concentration of the desired component of the sample. Because the proportionality does not involve the property of the individual sample component being measured by the chromatographic analyzer detector, it is possible to obtain a quantitative analysis of the concentration of the individual  components  of the sample without the need to calibrate the chromatographic analyzer detectors.

Abstract: ABSTRACT OF THE DISCLOSURE           In an adaptive delta modulation system, the delta modulated output signal is applied to a logic circuit which derives from such signal a pulse train used to develop the system's quantization step size control voltage.  The output pulse train of the logic circuit is applied to a circuit which serves the function of an integrator although digital in opera-tion.  The digital circuit develops a digital output signal whose value depends upon the number of pulses appearing per unit time in the logic circuit output pulse train.  The digital circuit in-cludes a forwards-backwards counter, whose forwards input receives the logic circuit output pulse train.  An accumulator which accum-ulates the count on the counter produces carry pulses at its highest-place stage, the carry pulses having a repetition frequency corre-sponding to the count on the counter, the carry pulses being ap-plied to the reverse input of the counter.  The count on the counter corresponds to the number of pulses appearing per unit time in the logic circuit output pulse train and is applied to a digital-to-analog converter, from the analog output signal of which the quanti-zation step size control voltage is derived.
