Abstract: A substantially radiation absorbing layer of metal having a microstructured surface characterized by a plurality of randomly positioned discrete protuberances of varying heights and shapes, which protuberances have a height of not less than 20 nanometers nor more than 1500 nm, and the bases of which contact the bases of substantially all adjacent protuberances is disclosed. The metal layer, which may be a coating on a variety of substrates, is useful as a radiation absorber (particularly solar). A method is disclosed for producing such layers.

Abstract: Pressure-sensitive adhesive tape, the adhesive layer of which is a copolymer of alkyl acrylate such as isooctyl acrylate and acid such as acrylic acid which differs from the prior art by including a small amount of lower-alkoxylated amino formaldehyde condensate as a latent crosslinking agent. The adhesive does not become crosslinked until it is heated. After the tape has been applied and heated to crosslink the adhesive, it exhibits excellent resistance to common organic solvents and also exceptional resistance to shear failure, especially at elevated temperatures. The adhesive has excellent electrical-insulating properties.

These primer compositions comprise at least one non-amino- or non-amido-containing silane, at least one of certain metal esters, and preferably an acidic material. The overcoatings are derived from epoxy and vinyl monomers. The primed and overcoated substrates of the present invention provide articles having protective, decorative, or other functional surface layers.

Abstract: A package for adhesive-surfaced sheet-like articles which may be delicate is formed by mounting the adhesive surface of the article onto a two-part release-surfaced carrier, one part of which supports the periphery of the article and the other part supporting the interior area of the article. With such a package, adhesive-surfaced sheet-like articles can be accurately placed onto an adherend without danger of contaminating the adhesive surface or allowing tearing, curling, or distortion of the article.

Abstract: A cartridge including a cylindrical hub attached to a housing, which hub has a central opening and a slot extending axially across the width of the hub and communicating with the central opening, and an endless length of magnetic tape having a major portion wrapped about the hub to form a coil and a minor portion extending from the innermost wrap of the coil, through the slot and around the side surface of the coil to the outermost wrap of the coil. Means on the housing define a tape path for the minor tape portion including a spring biased movable guide pin that provides a desired low, predetermined tension in the outermost wrap of the coil. A portion of the hub can be moved radially to adjust the length of the minor tape portion and thereby position the guide pin in a predetermined portion of its range of movement, and a lock assembly is provided for restricting movement of tape in the coil during shipping, which lock assembly is automatically released when the cartridge is inserted into a machine.

Abstract: High temperature phenolic resins suited for use for example in an automotive or similar brake or in a clutch, are provided by a blend of the reaction product of a phenolic compound, naphthalenic compound, and formaldehyde with selected prior art resins. The mole ratio range of naphthalenic compound: phenolic compound: formaldehyde is about 1: 1:0.8-5:1-10. Friction particles and friction elements can be prepared from said reaction product optionally being blended with said selected prior art resins. An improved method of making friction elements is also provided which uses such binder.

Abstract: A UV sensitive dry silver photothermographic construction for graphic arts use can be freely handled for one to two minutes under cool white fluorescent lighting or incandescent lighting. The construction comprises in sequence:a. a substrate,b. a continuous layer of a dry silver dispersion coating containing an organic silver full soap/half soap blend, a reducing agent, halide ion, and a binder resin, andc. a continuous protective topcoat layer comprising a cellulose acetate resin admixed with an effective amount of a development accelerator,said construction further comprising (1) halide ion in said silver dispersion coating or in said topcoat layer, said halide ion being at least 96 mole percent chloride ion, said halide ion when present in said dispersion coating being admixed in said dispersion subsequent to the admixing of at least a portion of said binder resin with said organic silver soap blend, and (2) an antihalation agent in any of the aforementioned layers or in a separate layer.

Abstract: An initialization apparatus for a signal reproducing apparatus having a transducer scanning a plurality of record tracks on a record medium where the position of the transducer is controlled by a stepper motor having fewer steps than the number of record tracks required to be covered. A physical stop is provided the transducer near a selected "home" record track at one edge of the plurality of record tracks. A current selector supplies the phase windings of the stepper motor with a reduced amplitude current during an initialization position. This enables a transducer controller to stop the stepper through a sequence of steps under reduced current to the phase windings of the stepper until the physical stop is contacted, thus ensuring knowledge of the initialization of the transducer at the "home" record track.

Abstract: Photopolymerizable compositions which comprise cationically polymerizable organic material and photosensitive aromatic iodonium salt of a halogen-containing complex ion are described as are coated substrates and methods for bonding materials together using such compositions.

Abstract: A novel light sensitive, heat developable imaging system incorporating a diazonium salt and a leuco dye in a binder is disclosed.

Abstract: A composition for use in liquid crystal display devices, consisting essentially of a nematic liquid crystal material and a helichromic compound possessing both a chromophoric moiety and a helical ordering moiety. The helical ordering moiety is capable of helically ordering the mixture of liquid crystal material and helichromic compound. The helichromic compound can be utilized in conventional "guest-host" and "twist nematic" displays as well as in unique helichromic displays. When used in helichromic displays, the helichromic compounds eliminate after-image scattering and enable the display to be operated at reduced voltages.

Abstract: A sheet feeder for feeding sheets from a stack thereof, which feeder automatically fans or separates the uppermost sheets within the stack to facilitate their feeding. The feeder includes a feed roll brake releasably coupled to a feed roll which brake rotates with the feed roll until a pre-determined force is applied on the brake by a spring that has been compressed by the normal feeding rotation of the feed roll, causing the feed roll to rotate in the opposite direction to the normal feed direction, thereby fanning the uppermost sheets.

Abstract: A visual display device is featured which uses a new thermal addressing technique to provide a dark image upon a lighter background. The display is capable of being multiplexed to a large number of rows. The device comprises a cholesteric-smectic liquid crystal material mixed with a pleochroic dye of high order parameter. When the material experiences a transition from a higher to a lower, smectic thermal phase, two different textures or light states are developed; a transparent state and a light absorbing state. The transparent state is developed by applying a sensitizing voltage to certain portions of the medium. The pleochroic dye absorbs the light passing through the unsensitized portions of medium to provide the dark image. The row electrodes are made diffusely reflective so as to provide a double light pass through the medium to improve contrast.

Abstract: A cleaning wiper adapted to automatically maintain a fresh cleaning surface upon each utilization. Supply and take-up holders are mounted in a body for holding rolls of a cleaning web. The cleaning web, intermediate the supply and take-up holders, passes over a support member movably mounted within and accessible through a slot in one side of the body. Utilization of the cleaning wiper causes the support member to be moved from its resiliently biased position within the slot and activates an advance linkage. The advance linkage advances the rotation of the take-up holder a predetermined amount.
