Abstract: A posturized bedding or seating product is provided comprising a spring assembly made up of a plurality of parallel rows and columns of coil springs joined to each other. Each coil spring comprises a pair of knotted end turns with a plurality of conically tapered central convolutions therebetween. Certain sections of the product are made firmer than other sections by inverting the coil springs of one section relative to another section.

Abstract: A mattress or seating spring core assembly and method of manufacture which comprises interconnected rows of coil springs wherein each row terminates in a cut wire end which is bent inwardly into one of the end coils and in which the spring core assembly is surrounded on all sides by foam panels and is devoid of any border rods.

Abstract: A nestably stackable bedding foundation assembly replaces the traditional border wire and disposed coil spring foundation assembly in a so-called box spring. The foundation assembly may be nestably stacked with numerous other such assemblies for transportation, thereby avoiding the need to compress and tie the assembly for shipping. Each foundation assembly includes a number of corrugated support wires having alternating peaks and valleys. The valleys of selected support wires are twisted relative to their associated peaks to provide a more stable mounting to a base and offer a variety of firmness to specific zones of the assembly.

Abstract: A gas sensor comprises a body (1) on which is mounted an optical source (7) and a detector means (8) sensitive to light from the source. The body further comprises a channel (5) arranged to admit gas, the channel comprising an elongated groove having reflective surfaces defining a folded optical path for light from the source. The groove is arranged as a serpentine shape or spiral shape so that light from the source to detector travels around the groove being internally reflected within the shape.

Abstract: A collar seal is configured for a turbine nozzle vane. The seal includes a retainer having a circumferential airfoil contour conforming with the airfoil contour of the vane. A flexible leaf is surrounded by the retainer and fixedly joined thereto. A woven sheath encases the leaf and is fixedly joined to the retainer. In an exemplary embodiment, the collar seal surrounds one end of a ceramic turbine vane mounted in a metal supporting band.

Abstract: The invention provides new methods for synthesis of percarbonic acid and methods of using percarbonic acid compositions for the treatment of substrates. The invention is particularly useful for cleaning, disinfecting and/or sterilizing a substrate using percarbonic acid or a percarbonic acid-carbon dioxide mixture. The invention further provides an apparatus suitable for use in the substrate treatment methods provided herein. The invention also provides methods and apparatus for the real time monitoring of the treatment processes provided herein.

Abstract: Returned checks are matched with related bank documents during a mail insertion operation. In the disclosed examples, the method and system utilize an imaging system to read the MICR account code line on each check payment document. The account number data from the check document is then compared to account number data for a related bank document and a match or mismatch is determined.

Abstract: An assembly for mounting an igniter in a gas turbine engine combustor between an outer casing and an outer liner, wherein a longitudinal centerline axis extends through the gas turbine engine. The igniter mounting assembly includes a first spring member encircling a portion of said igniter and being positioned between a surface adjacent the outer casing and an outer surface of the outer liner, a first ring member connected to a first end of the first spring member adjacent the outer surface of the outer liner, and a second ring member connected to a second end of the first spring member adjacent the surface adjacent the outer casing. Accordingly, the igniter is able to maintain substantial alignment with respect to an opening in the outer liner while moving radially and/or axially with respect to the outer liner as the outer casing experiences thermal growth greater than the outer liner.

Abstract: A machine for securing a border wire on a mattress inner spring comprises a support for supporting the mattress inner spring and border wire; a clip applicator for applying clips to the mattress inner spring and the border wire to secure the border wire to the mattress inner spring; a movement generating system for effecting relative movement between the mattress inner spring and border wire, and the clip applicator, such that the clip applicator successively secures clips to the mattress inner spring and the border wire around a perimeter of the mattress inner spring; a controller controlling activation and deactivation of the clip applicator and drive system; and a clip applicator feed system configured to receive and feed to the clip applicator a plurality of non-coiled strips of clips.

Abstract: A method for determining the configuration of a resin portion of an article comprising exposing the article to a light source at a first wavelength and measuring emission of light at a second, different wavelength; wherein the resin contains a moiety containing a structure of the formula: ##STR1## or a moiety which is a reaction product of said moiety in a quantity sufficient to impart fluorescent properties to said resin.

Abstract: A coupling for joining a pair of conduits, one of the conduits having a flared end and the other of the conduits having a circumferential flange with a surface conforming generally for mating with the flared end of the one of the conduits. The coupling comprises a first annular ring positioned about the one of the conduits and having an inner diameter less than an outer diameter of the flared end and a radially inner surface adapted for engaging an outer surface of the flared end. A second annular ring is positioned about the other of the conduits and has an inner diameter less than an outer diameter of the circumferential flange and has a surface adapted for engaging a surface of the flange. A split ring circumscribes the first and second rings and has a radially inner, generally V-shaped groove for simultaneously overlapping both the first and second rings.

Abstract: Dilution steam for steam cracking hydrocarbons to produce lower olefins is economically provided by saturating gaseous hydrocarbon feed with water at a temperature selected to achieve the particular steam to hydrocarbon ratio desired in the steam cracking step. Complete saturation of the feed gas is ensured by injecting the gas into the flooded portion of an indirectly heated tubular saturation zone.

Abstract: Combustion air for steam cracking furnaces is preheated by indirect heat exchange with medium pressure and low pressure steam that has been expanded through steam turbines from high pressure steam produced in the hot section of an ethylene production plant.
