Abstract: ABSTRACT     A rotary sample changer for a spectrofluorometer has a revolving turret base which can be indexed and which carries an interchangeable sample carrier.  Different sample carriers accom-modate test cells, test tubes and cuvettes of different sizes and shapes.         The revolving turret base and the interchangeable rotary sample carriers are constructed of material having good thermal conductivity and rotate on a large stationary hollow axle which is thermostated by thermally controlled internal fluid cir-culation to act as a heat source or sink to the samples.  Thus, the sample carriers can readily be interchanged without disturbing the plumbing by which the thermostatic fluid is circulated.           The revolving turret base is detented at the stations to which it is indexed without kinematic ambiguity and without application of any cocking force.  Two spring biased ball detents, symmetrically spaced 180° about the axis of rotation, are provided At the four index stations one ball catches on one of two indexing grooves spaced 90° apart, while the other ball bears against a flat.

Abstract: ABSTRACT OF THE DISCLOSURE        A synthetic resin tube having thick wall portions extend-ing radially outwardly and thin wall portions formed with a plurality of perforations.  The thick and thin wall portions are alternately arranged along the longitudinal direction of the tube. Each of the thin wall portions is further formed with an annular inwardly bent portion.  The method for producing such a tube comprises the steps of periodically varying an extrusion working space defined between movable and stationary dies, and installing a sizing die to regulate an inner peripheral surface of the extruded tube, while pre-cooling an outer surface of the tube by shower or mist and inner surface thereof by pressurized air.          The perforations are formed upon partial contact between the movable and stationary dies, and the annular bent portion is formed by the peripheral speed differential between first and second sets of rollers, both being adapted to drive the pre-cooled extruded tube.

Abstract: METHOD AND APPARATUS FOR REDUCING   ECCENTRICITY IN A TURBOMACHINE                                   Abstract An inherent eccentricity between the rotor bearings and the stator shroud is reduced by intentionally fabricating into each of a pair of frame annuluses, outer and inner surfaces which are relatively eccentric, and then rotating the annuluses with respect to each other until the inherent eccentricity is substantially offset. A method is provided to determine the optimum relative rotational positions as a function of the measured inherent eccentricity, and restrictions in the number of possible rotational positions are considered.

Abstract: ABSTRACT OF THE DISCLOSURE             SAIL ASSEMBLY     A skate sail is rigged with leading edge spars set by manipulation of a cruciform frame.  The sail and frame assembly is suitable for mounting on a boat or vehicle as well as for being hand held, and is collapsible for compact stowing.  When provided with a cinch line the sail assembly can be used for hang gliding.  Rigging is set by joining separable lengths of a mast and advancing a transverse brace along the mast toward the mast head to deploy by toggle-like action head spars to which the sail is lashed thereby spreading and drawing taut a trapezium configuration of sail foil which is anchored to the foot of the mast.  Laterally extendable wings may be provided and deployed separately to provide troughs which catch air spilling from the main sail foil and eas handling of the sail and enhance the ability of a user to trim the sail readily.

Abstract: ABSTRACT  ELECTRICAL CONNECTOR           This invention relates generally to modular electrical con-nectors useful, for example, in telephone interconnection systems or the like.  Prior art connectors have not proven effective for factil-itating prompt field service connection and reconnection of electrical circuits in selected circuit patterns with a minimum of effort and time by relatively unskilled personnel.  The present invention is effective in these respects by providing a first adapter, including an associated set of electrical contacts lesser in number than the contacts of a complementary connector, constructed and arranged for disposition at any preselected one of a predetermined plurality of positions on a support means, for adapting the electrical connector for mating engagement with only selected ones of the fixed contact elements of the complementary electrical connector according to the position of the first adapter on the support means to change the circuit through the connectors.  Complementary mounting devices are provided on the support means and the first adapter for releasably securing the first adapter at any one of a number of preselected positions.  A second adapter, including an associated set of electrical contacts, is supported by the support means In a fixed position for mating engagement with selected contact elements of a second comple-mentary electrical connector.  Conductor wires electrically Inter-connect the associated sets of electrical contacts of the first and second adapters.

Abstract: ABSTRACT OF THE DISCLOSURE           A tire building machine of the expandable bead lock type employs an elastomeric specially shaped radially expanding bead lock including a shaping and turning bladder which includes an air passage system there-through.  The elastomeric bead lock is confined for radial expansion in an annular outwardly opening chamber in the form of an isosceles trapezoid in radial section with the elastomeric bead lock being of similar configuration and expanded by direct application of air pressure within the chamber.  The configuration of the annular chamber and the bead lock compensate for stretching of the bead lock upon enlargement.  The edges of the bead lock at the axial sides of the chamber are undercut for flexibility while the walls of the chamber are specially costed to maintain the seal.  The bead lock incorporates interconnected metallic segment side plates which not only limit the stroke of the moving seal but insure stability axially of the bead and provide the desired concentricity.  The bladder is pressurized through an annular air passage system and a sealed conduit extending radially through the pressure chamber inside the bead lock.

Abstract: ABSTRACT OF THE DISCLOSURE          The manufacture of hydrogen and oxygen by the dissociation of water vapor at elevated temperatures followed by separation of hydrogen from the water vapor and the oxygen produced using a hydrogen permeable membrane is improved by increasing the surface area of the membrane exposed to the dissociation gas mixture.  One way of increasing the surface area of contact, according to an embodiment of the present invention, is to form a hydrogen permeable membrane coated on one side of a porous refractory wafer with an inlet hole through the wafer connecting the beginning of a grooved maze and an outlet at the end of the maze facing the opposite direction from the inlet.  A number of these wafers are then stacked or replicated front-to-back, with each outlet regis-tering with the inlet of the next wafer to give a compact and efficient hydrogen diffusion separator.
