Abstract: ABSTRACT OF THE DISCLOSURE     A multichamber cuvette for maintaining in independent and separate condition at least two reactants until such time that it is desired to mix them for reaction with each other and a reactant liquid sample while in the cuvette for analysis in the cuvette, and a method of use of such cuvette.  There is provided a cuvette body of a suitable plastic defining at least two chambers inter-connected by a passageway of relatively small cross-section having at least the end portion thereof of capillary size to prevent under many circumstances, as by surface tension accidental mixture of liquid reactants in the chambers.  If there is a substantial head of liquid in one chamber and/or a risk of impact of the cuvette with an external foreign object, sufficient to break such surface tension, an air lock in the passageway when the latter is below the liquid levels in the chambers prevents such accidental mixture.  A baffle in the passageway enhances separation of liquids and/or solid substances in the chambers.  The chambers are open-topped, and a unitary probe-wiping multi-ply laminated cover of a type puncturable by a probe extends over the chambers closing them from the external environment.  The laminated cover tends to be self-closing with reference to such punctures.          One ply is of metal foil to act as a vapor seal and has an undercoating of a heat sealable material compatible with the body material and sealed thereto.  The top ply is of a moisture-absorbent material which is secured to the foil ply by an intermediate plastic ply.

Abstract: METHOD OF DRAWING GLASS OPTICAL WAVEGUIDES                  Abstract of the Disclosure A method of making glass optical waveguides by the flame hydrolysis technique.  Particles of glass soot pro-duced by flame hydrolysis are deposited on the outside surface of a mandrel to form a porous preform.  The soot particles closer to the mandrel have a refractive index greater than that of the soot disposed toward the outer surface of the preform.  The mandrel is removed and the resultant hollow soot preform is supported in a draw furnace through which a helium-rich gas flows.  The preform is heated to a temperature sufficient to cause said soot to consolidate and simultaneously permit an optical waveguide filament to be drawn therefrom.

Abstract: HYDRAULIC TEST TOOL AND METHOD ABSTRACT         A test tool and a method of testing is disclosed for testing for leaks in apparatus having a bore and a landing surface, such as blowout preventers, wellheads, casing hangars, and the like.  The test tool is connected to pipe having a passage there-through, which has a landing surface for landing on the landing surface of the bore, bypass passages automatically closed on landing and during testing, packing means for effecting a seal in the bore, a pressure relief valve and hydraulic passages com-municating with the passage in the pipe, the packing means, and the relief valve which opens at a predetermined pressure.  The packing is set either hydraulically, mechanically or by a comb-ination thereof.  The packing is set hydraulically by a piston and cylinder which are activated by hydraulic setting pressure in the passages and then hydraulic test pressure is released by the relief valve to the space above the packing for testing the apparatus. When the test tool is set mechanically, the packing is compressed by the weight of the test tool and the pipe into sealing position by downward movement of a portion of the body after landing, the hydraulic testing pressure then assisting and maintaining the seal.

Abstract: DUAL FILTER ASSEMBLY FOR COMPRESSED GAS                  Abstract of the Disclosure A compressed gas filter assembly having dual filter units each containing an adsorbent and alternating between filtering and regenerating cycles, the units alternately receiv-ing compressed gas from a source for adsorbing a contaminant therefrom and having the adsorbent regenerated by reverse flow therethrough of filtered gas from the other unit and together providing an uninterrupted output of filtered gas from the assem-bly, and a regenerating line connecting filtered gas outlets of the units and having in each unit a restricted orifice centered on and directed toward a downstream end of a canister therein containing the adsorbent, each orifice alternately passing a me-tered flow of filtered gas under substantially constant pressure to the other unit and discharging filtered gas from the other unit as a substantially constant flow of gas at reduced pressure for regenerating and cooling the adsorbent in its unit.  A coni-cal deflector mounted centrally on a foraminous end plate at the downstream end of the canister, spreads the regenerating gas across the adsorbent and protects the end plate from damage by any particulate matter discharged from the orifice with the gas.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed herein is a process of compression stressing a metal workpiece having a body with a central bore so as to produce a residual compressive stress in the workpiece to increase the fatigue strength of the workpiece.  The process includes the steps of forcing the workpiece onto a mandrel to induce an initial tensile stress in the body, thereafter inducing a compressive stress in the surface of the workpiece by shot blast treatment of the surface of the workpiece, and there-after separating the workpiece from the mandrel to increase the compressive stress in the surface of the workpiece.

Abstract: Abstract of the Disclosure Apparatus for mounting and demounting tires and methods of mounting and demounting tires.  The apparatus may include a clamp for holding a wheel as well as a tire clamp and pushing device for gripping a tire and applying a moving force thereto.  The tire clamp is mounted for move-ment toward and away from the wheel clamp and toward and away from a support for the wheel clamp.  It is operated, during tire mounting, to nonaxially urge a tire having one part of one bead received in the drop center of a wheel away from the wheel to draw that part into the drop center while axially moving the tire at a remote location toward the wheel so that the beads at the remote location are disposed between the flanges of the wheel. Both beads at the remote location are also brought towards each other into sufficient proximity so that both may enter the drop center of the wheel and thereafter, the tire is nonaxially urged at the remote lo-cation toward  the wheel to dispose both the beads at the remote location within the drop center of the wheel.  There-after, the tire is axially moved toward the wheel causing the remaining part of the bead to be received between the wheel flange.  In demounting the tire, the tire clamp is uti-lized to bring the beads at one location into sufficient proximity such that both may enter the drop center of the wheel and thereafter, the tire is nonaxially urged in a direction to cause both of the beads to enter the drop center of the wheel.  Oppositely therefrom, the tire is axially moved away from the wheel until both beads at the opposite location, are moved from between the wheel flanges.
