Abstract: A gable-top thermoplastic coated container with controllably enhanced sealing and opening characteristics includes at least one stiffening fillet attached to the gable rib panels and/or roof rib panels which form the spout. The fillet comprises a thin strip of stiff material coated with a layer of adhesive, and is bonded to the gable rib or roof rib panels. The strip is resistant to the thermal container-sealing process, and extends along a major portion of the panel length to increase the force which may be transmitted to the tip of the spout where the gable rib panels are adjoined, and prevent buckling of the spout panels. An adhesive web is delaminably bonded with a controlled release adhesive to the opposite surface of the strip, and is bonded to the other one of the gable rib panels and roof rib panels by the container sealing process.

Abstract: Wax-base or emollient-base cosmetic compositions may be provided as samples on paper carrying sheets by providing the paper with materials that prevent absorption of oleic materials and providing the cosmetic compositions with a lower sheet that is oleophobic. A binder layer of an oleophilic wax or polymer may be used between said paper and the cosmetic composition. A frangible, thin polymeric film is placed over the cosmetic composition to prevent shear forces and pressure from smearing the composition.

Abstract: Retroreflective sheeting has been improved by a coating comprising silica and a transparent polymer selected from aliphatic polyurethanes and polyvinyl chloride copolymers having a minor amount of a comonomer containing at least one carboxylic acid or hydroxyl moiety. Silica comprises 10-80 weight percent of the transparent protective coating. For example, a solution or dispersion of polyurethane is mixed with a silica sol and possibly other ingredients (e.g. wetting agent, UV light absorber and adhesion promoter), and the composition is coated onto the retroreflective sheet and dried. The coated retroreflective sheeting has superior soil and dew repellancy, retaining a higher percentage of original brightness after exposure to dirt and/or dew conditions.

Abstract: A lens of a transparent material including a structured surface on one side and a smooth surface on the opposite side. The structured surface includes a plurality of three-faceted prisms arranged side by side to form a plurality of ridges and grooves. Each prism has a reflective surface adjacent to a refractive surface and a riser adjacent to the refractive surface. The surfaces are angled with respect to one another so that incident light is transmitted through the lens, whereby the exiting rays may be predisposed to be perpendicular or non-perpendicular. Because of this the lens can be used to disperse, collimate, gather or concentrate the light. Thus, it may be utilized in a variety of ways, for example, in a light fixture, whereby high-angle incident light directed toward either the structured surface or the smooth surface, is transmitted through the lens and is directed in a desired fashion.

Abstract: Spectral sensitizing dyes which sensitize photoinitiators and disperse in aqueous solutions are desirable in photosensitive systems where precise color rendition is important.

Abstract: A stapler having a spine structure between a staple carrying head assembly and a manually operable actuator assembly that can be made either flexible or rigid as desired during use of the stapler.

Abstract: A data cartridge which is edge loaded must be loaded before the access door is opened, permitting the head to enter the cartridge but entry and opening of the door can be accomplished when the head is moved vertically from a first lowered position to an upper operative position against the tape and to permit movement of the head to the upper operative position, the tape must be temporarily moved from its path in the cartridge to permit vertical movement of the magnetic head without contacting the tape. The present invention permits tape movement and head positioning upon operation of a cam shaft with a front knob.

Abstract: A tape leader is fastened to a reel hub by a spring clip fitting across a slot in the hub rim. The clip has a "J"-shaped portion which slides against a support in a camming action to force an end part of the portion against the leader and an inner surface of the rim. The sprung clip crosses the slot and is held in position at the other edge of the slot by a spring catch.

Abstract: The presence of certain chemicals on the emitting surface of the surface-derivatized photoluminescent semiconductor alters the characteristics of radiation emitted from said surface. This alteration is used to indicate the presence of those chemicals in the environment.

Abstract: A demagnetization apparatus for use with magnetically based electronic article surveillance systems having a dual status anti-theft marker containing at least one demagnetizable control element which when demagnetized allows the marker to be detected by the system when the marker is present in an interrogation zone. The apparatus includes an elongated magnetic section contained within a housing which exhibits a succession of fields of alternate polarity and a portion of which exhibits generally decreasing intensities at the working surface of the housing along that portion of the section. The peak intensity of the outermost field is controlled to have a peak intensity less than that of adjacent regions. The section and a cover plate are oriented such that the external fields near the working surface are sufficient in intensities to demagnetize the demagnetizable element of the marker positioned proximate thereto while being rapidly attenuated a short distance from the section.

Abstract: Ethoxylated siloxane surfactants, and mixtures of such surfactants with curable silicone prepolymers. The mixtures are hydrophilic after cure, have semipermanent hydrophilicity, and are especially useful as dental impressions.

Abstract: A tape spool provides resistance to disassembly from shocks caused by rough handling by providing an annular hub projection extending axially of the spool hub to define a shoulder which interacts with an inner radial wall of a disk providing the second flange of the spool. The inner radial wall of the disk defines a central hole surrounding the hub projection, with contact between the radial wall of the disk and the shoulder of the hub restricting radial movement of the disk with respect to the hub. The disk and the hub also may include intermeshing splines which prevent relative rotation of the disk and the hub.

Abstract: Method for preparing photosensitive silver halide crystals. A binder resin, a source of halide ions, and a source of silver ions are dissolved in an organic solvent, e.g., ethanol. Silver halide nuclei will then form. Additional source of halide ions and additional source of silver ions can be added to the solution in incremental additions, so that the initially-formed silver halide nuclei will grow. Upon removal of the solvent, the silver halide crystals will exist in a dry state, entrapped in the binder resin. Silver halide crystals formed and grown in this manner can be used to prepare photothermographic imaging compositions, which compositions will exhibit higher speed than photothermographic imaging compositions containing silver halide crystals grown according to conventional methods.

Abstract: A pressure-sensitive adhesive layer is crosslinked between carboxyl groups along one surface by polyvalent cations, thus making that surface substantially tack-free while leaving at least one broad surface of the layer tacky and pressure-sensitive. When a broad surface of the adhesive layer is thus made completely tack-free, the adhesive layer can be wound upon itself in roll form without a backing for convenient storage and shipment. Preferably a low-adhesion backsize coating covers the broad tack-free surface to insure that the adhesive layer can be unwound after prolonged storage without delaminating.

Abstract: A zoom lens system having magnification factors in the range of 20 to 47. The lens system of the present invention is particularly useful in micrographic reader/printers.
