Abstract: A method of preparing a prelaminate for a safety glazing which involves providing a thermoplastic interlayer having a first air removal surface which includes a multiplicity of microscopic embossments of substantially identical shape integrally projecting from the plane of one side of the interlayer in a regular pattern of rows and a second air removal surface on the other side of the interlayer which is different from the first air removal surface and includes a multiplicity of microscopic peaks and valleys of varying heights and depths arranged in an irregular, non-linear pattern, interposing the interlayer between two layers of glass and deairing the interfaces with the glass layers during which the first air removal surface is partially transferred to and imposed on the second air removal surface to provide deair paths of reduced obstruction.

Abstract: A process for forming a shaped prelaminate of glass and plastic by a) drawing an assembly of plastic layers against a hot, contoured, e.g. of compound curvature, mold surface to provide a shaped plastic preform at elevated temperature; b) transferring the shaped preform without cooling to an adjacent unheated glass layer of substantially matching surface contour to heat bond the shaped plastic preform to the glass layer; and then c) removing heat from the shaped plastic preform via conductive heat transfer to the glass layer to form the shaped prelaminate of glass and plastic layers. A bilayer glazing panel is formed in a conventional unmodified autoclave bonding system by exposing the prelaminate to elevated temperature and pressure to firmly bond the plastic to the glass.

Abstract: Deep-dyeing conjugate filaments are melt-spun by merging molten sub-streams of incompatible polymers to form combined streams, then quenching the combined streams to form the conjugate filaments. The filaments are preferably cold drawn prior to winding, increasing the bulk level in a fabric containing the filaments and increasing the dye stability of the filaments. When the sub-streams are merged outside of the spinneret, the filaments split into the sub-filaments upon exposure to boiling water while under no tension. When the sub-streams merge within the spinneret, the filament is not readily split into sub-filaments, but forms a helically crimped filament.

Abstract: Hybrid curable compositions comprising components curable by condensation, and components curable by free-radical initiated polymerization, cure being catalyzed by a metal sulfonate. The components curable by condensation comprise amino resins and co-reactants. The components curable by free radical initiated polymerization comprise acryloyl compounds and allylic or vinylenearylenemethylidyne compounds.

Abstract: Ethylenically unsaturated carbamates prepared by addition of unsaturated isocyanates to the hydroxy groups of styrene allyl alcohol copolymers are formulated with allylic monomers and unsaturated co-reactants selected from (meth)-acryloyl monomers and oligomers, maleates and fumarates to provide air-dry-and heat-curable coating compositions.

Abstract: The invention discloses an acylated pentapeptide that inhibits metastasis activity of malignant cells.

Abstract: Removal of molten slag from combustion chambers for combustion of combustible gases containing entrained slag-forming particulates, is frequently a problem since the slag tends to solidify in the tap-hole resulting in bridging and eventual pluggage of the tap-hole. This invention eliminates this problem by providing a dam around the periphery of the tap-hole of sufficient height to maintain a pool of molten slag on the inclined bottom of the combustion chamber to a depth whereby said slag pool is an effective heat sink to maintain the molten slag in flowable condition, and by providing in the dam at least one inclined drain trough which over-hangs the tap-hole a sufficient distance to minimize contact of draining slag with the walls of the tap-hole.

Abstract: A wafer packaging system for clean packaging and damage-free transporting of semiconductor wafers. The system includes tubular outer and inner containers, the inner container adapted to be contained by the outer container with the longitudinal axes of both containers extending in the same axial direction. The inner container includes provision for holding a plurality of the semiconductor wafers in spaced face-to-face relationship. The system provides a sealed container arrangement preventing contaminants outside the outer container from contaminating wafers within the inner container. Shock-absorbing features associated with the containers prevent shocks applied to the outer container from damaging the wafers.

Abstract: A small portable device quickly secured to and removed from a body of monocrystalline material to be sawed and useful for aligning the body with respect to a saw blade, permitting sawing with precisely predetermined crystallographic orientation. The device has a viewing screen, a light source, and first and second autocollimators. The first autocollimator directs a first collimated light beam toward a surface of the material. The resultant reverse reflection is directed back through the collimating lens and a beam splitter images the reflection on the screen, providing a pattern on the screen characteristic of a crystallographic plane of the material, the pattern position corresponding to the orientation of the device with respect to the crystallographic plane.
