Abstract: A method of making abrasive articles which includes the steps of sandwiching and adhering abrasive particles between two sheets of fiber where the particles have a major cross-section dimension greater than the thickness of the sheets into resultant second sheets. The resultant second sheets are then adhered together by lamination under pressure so that the abrasive particles of a second sheet enter the interstices between the abrasive particles of adjacent other second sheets to form an interlocking bond and increase the tensile strength. The sheets are preferably cut from a processed strip prior to lamination. Prior to lamination the second sheets may be coated with one or both of a liquid rubber and a thermosetting resin. If resin is used the stack is heated as it is pressure laminated. The application of rubber and resin may be in the alternative. The application of rubber imparts flexibility while the resin upon curing imparts hardness.

Abstract: A grinding material or product which may be utilized in different forms and comprises laminated layers which interlock with each other when laminated to provide greater tensile strength. Layers of the basic material are formed by sandwiching abrasive particles between two layers of pre-bonded carded fiber. One sheet of a layer is initially passed through an adhesive and later spread in a controlled fashion with abrasive particles. A second sheet of the carded fiber is passed together with the first sheet through a pair of nip rolls which compress the two sheets together with the abrasive particles therebetween and provide a first layer of adhered sheets with the abrasive particles therebetween.Subsequently, the resulting layer may be cut into sections and a plurality laminated together for a desired thickness.

Abstract: The disclosure shows the use of a plurality of individually moveable probes in an X-Y plane which may contact points of networks on a circuit board on either side thereof and measure the discharge time of a charged network. The specification also discloses the utilization of a common connector to a conductive reference plane to provide a terminal point for any of the plurality of probes. Each probe is a dual-purpose probe in that it may be utilized for a discharge test of each network, or it may be used in a combination with another probe to measure the resistance of a network. In most instances, the circuit board under test will include a common conductive reference plane which may be utilized as one side of a test source. Each network is tested as to discharge time against a norm which is previously determined; if the discharge time is too long above the norm, such long discharge time will indicate a possible fault.
