One-part moisture-curable polyurethane adhesive, coating, and sealant compositions

Abstract: Adhesive, coating, or sealant compositions containing prepolymer(s) derived from MDI (or derivative(s) thereof) and polyol(s) containing primary hydroxyl groups, together with bis[2-N,N-dialkylamino)alkyl]ether(s).

Subcutaneous housing assembly

Abstract: A housing assembly for electronic circuitry that can be used subcutaneously. The housing assembly comprises container and base subassemblies each comprising a ceramic portion and a continuous metal sealing flange having a first portion brazed to the ceramic portion around its periphery, and a second portion spaced from the ceramic portion. The ceramic portion of the container subassembly is dish-like to define a cavity, and has a plurality of electric leads brazed to and extending through it. Electronic components are placed in the cavity and attached to the leads, after which the sealing flanges are nested together and welded together along the distal edges of their second portions to close and seal the housing assembly.

Data processing form

Abstract: A data processing form for providing control information to apparatus, such as facsimile machines, having a scanner. The form has darkened areas which establish a row and column format with an elongate edge mark provided for each row. The edge marks extend to the edge of the form. Areas to be filled in by a user are defined using some of the darkened areas. The form format minimizes the software needed for circuitry used to process the information obtained from the form serving to reduce the time needed to scan the form.

Abrasive article and method of making same

Abstract: The invention provides an abrasive article having a surface having a machine direction axis and opposite side edges, each side edge being parallel to the machine direction axis and a plurality of parallel rows of abrasive composites in fixed position on the surface, each row being aligned at an angle with a side edge which is neither 0° nor 90°, and methods for making such an abrasive article The abrasive article of this invention also can be used in any convenient form including an endless belt The resulting abrasive article provides a high rate of cut, long belt life, and a relatively fine surface finish on the workpiece being abraded

Self-packaging bioelectrodes

Abstract: A bioelectrode (10) having a backing (12), a conductive layer (28, 30) adjacent to the backing (12), and a layer of conductive adhesive (36, 38) adjacent to the conductive layer (28, 30). This bioelectrode (10) is designed to have two special configurations. It is originally manufactured in its first configuration wherein the backing (10) forms a sealed protective enclosure for the layer of conductive adhesive (36, 38). When a physician is ready to apply the electrode (10) to a patient, the electrode (10) is readily converted to its second configuration wherein the layer of conductive adhesive (36, 38) is exposed for contracting and adhering the bioelectrode (10) to the body of the patient.
