Abstract: A cigarette mouthpiece of substantially cylindrical configuration assembled of two identical semi-cylindrical sections disposed in mutual concavely facing relationship with each longitudinal edge of one section in abuttment with a different one of the longitudinal edges of the other section. When assembled into a mouthpiece, the semi-cylindrical sections cooperate to define a plurality of generally longitudinally extending air ventilation grooves equally spaced from each other around the perimeter of the mouthpiece and a plurality of smoke flow capillaries extending generally longitudinally through the mouthpiece.

Abstract: Novel bicyclo [2,2,1] heptanes and hept-2Z-enes are substituted at the 5-position by a 6-carboxyhex-2-enyl group or a modification thereof, and at the 6-position by an aldoxime or ketoxime group which is O-substituted by an aliphatic hydrocarbon residue, an aromatic residue, or an aliphatic hydrocarbon residue substituted directly or through an oxygen or sulphur atom by an aromatic residue. Such compounds may be prepared by the action of an oximating agent on an intermediate which is substituted at the 6-position by an aldehydic or ketonic carbonyl group. The compounds are of value for use in pharmaceutical compositions particularly in the context of the inhibition of thromboxane activity.

Abstract: A bolt elongation measurement apparatus and method for measuring the length of bolts of all sizes and shapes. The apparatus utilizes a microprocessor-based digital system including a binary counter which counts pulses generated by a high frequency oscillator during the time interval between the entry into the bolt of a first pulse and exit from the bolt of a second pulse derived from the reflection return of ultrasonic energy from the opposite end of the bolt. The count is applied to a computer for calculation of bolt length or of bolt stretch due to mechanical stress. The calculation also incorporates data input via thumbwheel switches and corresponding to material velocity, stress correction factor, measurement temperature, and thermal correction factor. A unique digital filtering algorithm ensures an accurate and stable measurement.

Abstract: This invention is a method for effecting preferential removal and immobilization of certain gaseous contaminants from gaseous UF.sub.6. The contaminants include fluorine and fluorides which are more reactive with CaCO.sub.3 than is UF.sub.6. The method comprises contacting the contaminant-carrying UF.sub.6 with particulate CaCO.sub.3 at a temperature effecting reaction of the contaminant and the CaCO.sub.3.

Abstract: The present invention relates to a method for treating an aqueous medium containing magnesium sulfite tri-hydrate under precipitating conditions which method comprises adding to the medium an effective amount for the purpose of a sulfur-containing lignin.

Abstract: A non-destructive bond testing apparatus utilizes impedance variation represented by both the phase and amplitude of the signal vector response of a sonic energy generating and receiving probe, which is applied to a laminar, honeycomb or fiber composite structure under test. Typical bonding methods for which this bondtester and method are applicable include adhesive bonding, diffusion bonding, brazing, resistance and impact/friction bonding. A cathode ray tube displays the tip of the vector (as a bright dot) which represents the impedance characteristic affected by the structure under test.

Abstract: A composition is disclosed for use in dispersing magnesium sulfite tri-hydrate in an aqueous medium which composition comprises, in combination, an oligomer and a copolymer of a 1-olefin and an unsaturated anhydride.

Abstract: Automatic tracking of a source of radiant energy to pivotally displace an energy collector panel assembly for optimum concentration of the radiant energy absorbed. Changes in magnitude and/or location of the source relative to the collector produces a change in differential air pressure in a sensor to displace the center of mass of a gravitational drive device through which tracking movement is imparted to the collector panel assembly.

Abstract: A pressure regulator especially suited for cryogenic fluid and two-phase (gas and liquid mixture) flow application such as an aircraft fuel tank inerting system wherein the regulator controls the pressure and rate of flow of inerting fluid, e.g. nitrogen, into the fuel tank to pressurize the tank and to inert the tank ullage gases to render them noncombustible, said regulator being characterized in that the flow control valve has large and small variable area orifices which operate in sequence to minimize overshoot and undershoot, in that resonant oscillation is predictably damped and the damping remains substantially constant despite wear or change in clearances of the parts, and in that the valve actuator is thermally isolated from the cryogenic fluid flow path.

The outer portion is secured to one of the elements and the center portion is secured to the other by a rigid post.

Abstract: An apparatus and method for processing a paper strip wherein the paper strip is composed of a series of closely spaced photographic prints and wherein the paper strip has been marked with various indicia indicating the location of the prints and whether the prints are satisfactory. The apparatus includes means for advancing the strip along a path of travel, means for printing a customer identification number on each of the prints, means responsive to the indicia for cutting the strip between adjacent prints, and means responsive to the indicia for sorting the unsatisfactory prints into a separate receptacle.
