Abstract: Replacement of all or most of the coarse mineral in a coated abrasive product by a superior (and typically more expensive) mineral improves abrading performance significantly more than would be predicted. In some cases the performance is superior to that of products made with either mineral alone. The mineral is typically applied in two layers, substantially all of the coarse mineral being applied in the second layer. Superiority is defined in terms of a test that measures the comparative ability of different minerals to abrade cold rolled steel.

Abstract: Coated abrasive binders made from a photocurable addition-polymerizable composition containing a free-radically-polymerizable monomer and a photoinitiator system containing (i) an arylidonium salt, (ii) a sensitizing compound, and (iii) an electron donor having an oxidation potential that is greater than zero and less than or equal to that of p-dimethoxybenzene (1.32 volts vs. S.C.E.). The binders cure rapidly and deeply under ultraviolet or visible light, even when filled with large amounts of mineral grain or with coarse grades of minerals.

Abstract: A process for preparing a graphic pattern on a carrier having a protective coating thereon in exact registration with the pattern, and the article produced thereby. The process comprises applying a liquid protective coating over the graphic pattern slightly beyond the edge definition of the pattern and in substantial registration therewith, the protective coating having sufficient surface tension to wet the graphic pattern, but not the surface of the carrier. When the protective coating is dried, it dewets and retracts from the surface of the carrier onto the graphic pattern and provides exact registration therewith.

Abstract: An elliptical section mirror is placed with its concave side turned towards the surface of a stimulable phosphor panel to detect and deflect towards the second of its focal segments the light emitted by the phosphor after the scanning thereof with a stimulating ray passing through an opening of the mirror. The panel, the emitting surface and the emitting depth of the panel passes through the first focal segment of the mirror and the stimulating radiation impinges upon the panel, preferably in a perpendicular direction, along said first focal segment. A light guide having a straight-line inlet end placed in the second focal segment of the mirror is impinged upon by the light coming from the first focal segment and transfers it towards a photodetector through an outlet end.

Abstract: Replacement of all or most of the coarse mineral in a coated abrasive product by a superior (and typically more expensive) mineral improves abrading performance significantly more than would be predicted. In some cases the performance is superior to that of products made with either mineral alone. Typically 5% to 30% of the total mineral weight is made up of the superior mineral.

Abstract: Circuitry for the validation of repetitive signals including input/output circuitry providing information regarding signals received that is connected to a progammable microprocessor, a read only memory and random access memory. The microprocessor is programmed so the circuitry determines the receipt of an input signal at any one of several signal inputs. When a first signal is received at one of the signal inputs a "lock-out" time interval is provided during which another signal cannot be received at any signal input. This is followed by a "window" time interval during which another input signal can be received at the signal input receiving the first signal. A "lock-out" and a "window" time interval are provided for each signal received at the signal input during a "window" time period at which the first input signal was received. Such signals are counted until a predetermined count is reached thereby establishing the received signals as valid signals.
