Abstract: A stethoscope chestpiece has a body member, a tubular shaft, and an indexing detent. The body has a plurality of microphones each of which has a opening at its apex and a central recess. The tubular shaft is rotably secured within the central recess and has an opening in its wall that aligns selectively with one of the openings from the microphones. The sound conveying detent is mounted transversely within the shaft and aligned with the opening in the shaft wall. The indexing detent has a hollow cylindrical element and spring. The hollow cylindrical element has an open bottom and a seat end having an opening. The seat end is beveled and extends beyond the opening in the shaft wall to engage the body. When the seat end is aligned with a selected one of the openings from the microphones it seats to hold the opening from the microphone in alignment with the opening in the seat end to create a sound passageway into the tubular shaft.

Abstract: A flexible low-adhesion carrier web has a coating in the form of graphics including a matrix resin, a binder resin, and a light-altering agent such as a pigment. When the coating in wet with a transfer fluid such as mineral spirits, this activates the binder resin to permit the graphics to be transferred to a display surface such as a glass window.

Abstract: A photographic control device for scanner and exposure control system calibration in a photographic printer includes a carrier disk to present an open scan aperture in the scan gate for normal printer operation, and selectively a plurality of control patches in the scan gate for calibration of the scanner at startup. The disk is driven by a stepping motor and timing belt, the disk position being controlled by a position sensor tied in with the drive motor. The disk is mounted by three rotatable bearings spaced around its periphery.

Abstract: Retroreflective construction comprising a monolayer of microspheres with associated dielectric mirrors which are hemispherically surrounded by tangentially-oriented, preferably contour-conforming, reflective pigment nacreous flakes. The dielectric mirrors and reflective nacreous pigment flakes cooperate additively substantially without interfering with each other to provide a high brightness retroreflective sheet. The novel sheets retain much of their reflectivity after several launderings or drycleanings and, in some embodiments, can be made very flexible, making them well-suited for use as reflective fabrics.

Abstract: A gable-top container made from a scored blank of paperboard and the like includes at least one fillet permanently attached to the outside surface of the gable rib panels which form the spout. The fillet comprises a thin strip of stiff material coated with a layer of adhesive. The strip is resistant to the carton-sealing process, and extends along a major portion of the panel length to transfer to applied container-opening forces to the tip of the spout where the gable rib panels are adjoined, preventing buckling of the gable rib panels. In the preferred embodiment, the portion of the fillets on the adjoining gable rib panels abut one another when the spout is in a closed condition. A secondary layer of adhesive having a lesser bonding force may overlay the abutting portions of the fillets to controllably seal the gable rib panels to each other at the particular desired bond strength.

Abstract: An automatic film takeup reel to capture the free end of a film and wind the end, must guide the film along a feed passage formed by a housing toward a rotating reel of a soft material. The end of the film is held to the reel by a ball biased by a spring toward the reel and is directed around a cavity until wound. A spring biased arm then shifts the housing axially of the reel to afford continued winding.

Abstract: A process for preparing a transfer graphic article having a protective clear coat in precise registration therewith such that the graphic has rounded and sealed edges, and the article produced thereby. The edges of the underlying adhesive are sealed by the clear coat such that improved solvent resistance is achieved.

Abstract: Selecting proper half-tone screen systems for use with raster scanned images ensures the absence of Moire effects when using two or more color separations. Mathematical analysis provides an ensemble of screen patterns which are based on an odd/even relationship between the number of screen "lines" per repeat cell distance for combinations of screens. From this ensemble a critical selection is made of suitable screen parameters for the chosen font(s) using computer integration over repeat cell areas to show which chosen screens give invariance of white fraction with off-set distance in the two directions (horizontal and vertical). This comparison is carried out between all pairs of the required number of screens to be used.

Abstract: Pavement marking comprising ceramic microspheres held by a binder, said microspheres being solid, transparent, non-vitreous, ceramic particles which serve as lens elements in the retroreflective pavement markings. The ceramic microspheres formed by various sol gel techniques are characterized by having:A. at least one metal oxide phase; andB. an average minimum dimension of up to 125 micrometers.The inventive pavement markings retain reflectivity for a surprisingly long time.

Abstract: An aqueous alkaline photographic silver halide developer composition comprising a dihydroxy benzene developing agent, an auxiliary superadditive developing agent, an antifogging agent, an antioxidant and a buffering agent, characterized by the fact that the composition further comprises a stabilizing amount of an .alpha.-ketocarboxylic acid.The developer composition has a better resistance against air oxidation and can be left in continuous transport automatic processors for several days without undergoing any substantial decrease of its developing properties.The developer composition is particularly useful in a process for the formation of a high contrast silver image by developing silver halide photographic elements including at least a negative acting surface latent image type silver halide emulsion in the presence of a hydrazine compound, preferably in the additional presence of an effective amount of a contrast promoting agent.

The protein immobilizer can be a polymer or silane-functional compound. The biologically active protein can be the enzyme, catalase, which has use in decomposing hydrogen peroxide when disinfecting contact lenses.

Upon rupture of the microcapsules, the coloration of the second pigment is added to the composition, altering its color characteristics.

Abstract: Homogeneous, nonporous ceramic fibers containing at least one magnetically-unaligned, microcrystaline transition metal oxide spinel phase. The ceramic fibers may be used in polymeric, ceramic and metallic composites. Said ceramic spinel is produced by dispersing soluble inorganic and transition metal compounds in an aqueous mixture, concentrating to produce a viscous concentrate, shaping into the desired article, gelling the shaped article, and heating to produce the transition metal spinel article.
