Abstract: A stair modeling system having a storage resource with standard stair design values stored in the storage resource and a processor. The processor executes application code instructions to cause the system to receive user defined standard stair design values and user defined stair design values. The instructions further cause the system to generate stair design data associated with dynamically manageable and displayable objects, the stair design data and control data defined by at least one of the user defined standard stair design values and the user defined stair design values. The instructions further cause the system to process the stair design data and control data by comparing the user defined standard stair design values and the user defined stair design values with the standard stair design values and recalculate the user defined standard stair design values and user defined stair design values, and automatically regenerate stair design data.

Abstract: An anchoring device having a length of reinforcing material, a shell section attached to the reinforcing material, wherein the shell section has a hollow inner core, and a wedge located at least partially in the inner core of said shell section. In one embodiment, the wedge section is integral with the reinforcing material. In a preferred embodiment, the shell section has four segments and the wedge and the shell section have circumferential barbs on an outer portion thereof to provide greater retention properties for the anchoring system.

Abstract: A shippable in-assembly bolt having a head portion, a threaded portion containing threads and a gripper portion, wherein said gripper portion preferably comprises a grooved structure and an o-ring. The o-ring is intended to sit between the inner wall of a clearance hole in an assembly/subassembly and the grooved structure of the gripper portion. When the o-ring is in position between the inner wall of the clearance hole and the grooved structure of the gripper portion, the o-ring is in both compression and tension and acts to retain the bolt in the assembly during shipping operations. The invention can be used with any type of mechanical fastener, such as bolts, screws, pins, rivets, etc.

Abstract: A battery terminal bolt preferably having a head portion, a washer portion, a sealing portion and a threaded portion. The sealing portion is disposed between the washer portion and the threaded portion and is preferably in the form of a frustoconical shape that allows the bolt to be substantially sealed when placed in an insert mold. The battery terminal bolt's washer portion has a geometry that substantially reduces abusive field torque failures and also provides increased pull-out strength. In a preferred embodiment, the washer portion contains semi-circular projections in a radial pattern around longitudinal axis of the battery terminal bolt.

Abstract: The invention relates to a novel process for the chemical sensitization of silver halide photographic emulsions.The process according to the invention comprises adding as additional sensitizing agents a 40-260 .mu. moles/mole of a cyclic polyether containing 1 nitrogen and 5 oxygen atoms, or 2 nitrogen and 4 oxygen atoms, or 3 nitrogen and 3 oxygen atoms, or 4 nitrogen and 2 oxygen atoms as well as 12 carbon atoms and/or their complexes formed with gold and/or palladium and optionally 40-260 .mu. moles/mole of silver halide) of gold (I) or gold (III) sulfide to the sulfur-sensitized emulsion, and employing the cyclic polyether in relation to the noble metal salt in a molar ratio of 0.5:1-5:1 for the complex formation.

Abstract: A process for making printed circuit cards is disclosed wherein a copper clad, insulating substrate having a layer of copper from which circuitry lines and patterns will be fabricated, is coated with a thin layer of nickel prior to forming any circuit patterns.

Abstract: A structure comprising on a substrate successive layers of metal circuitry having therebetween as a dielectric a cured polyimide composition containing a polyimide and aluminum oxide or zinc oxide or mixtures thereof.The structure is produced by a method including the following process steps:blanket screen printing a mixture containing a polyamido carboxylic acid, aluminum oxide or zinc oxide or mixtures thereof and a detackifier with the rest being a solvent on a substrate with a layer of metal circuitry thereon,drying the deposited layer at a temperature between about 25.degree. and about 120.degree. C.,selectively etching holes into the deposited layer where vias between adjacent layers of metal circuitry are needed,curing the deposited layer at a temperature between about 300.degree. and about 400.degree. C. andforming another layer of metal circuitry.

Abstract: A screenable and strippable solder mask composition which contains a polyepoxide or polyimide/amide; a detackifier and a high-temperature resistant filler; and use thereof for protecting predetermined areas on a substrate from the solder deposition.

Abstract: The porosity and surface roughness of ceramic substrates are improved by coating the surface with silicon compounds, drying the coated substrate, and then subjecting the substrate to elevated temperature so as to convert the silicon compounds to silicon oxides. Coated substrates obtained by the above process as well as specific preferred organosilane compositions are provided.

Abstract: A film-forming composition comprising an organic flux base material; and a carboxylic acid anhydride and/or aldehyde; and a process for using are provided.

Abstract: A ceramic substrate is provided with via holes and these holes are primed by first depositing a palladium coating to the inside surface of the holes and then depositing an iron film onto the palladium. The primed holes are then completely filled with copper to provide conductive connections between opposite surfaces of the substrate. On one side of the substrate, input/output connector pins are brazed to the copper fillings. On the other side, printed circuitry is applied to produce a circuit module.
