A testing device for testing the quality of through-hole plating of a printed circuit board employs probes having pyramidical tips, with the edge of the probe tips contacting the ends of the through-hole plating. The probe edges are insulated from each other, so that the device can easily carry out Kelvin four-point testing. Because contact is needed only at the probe edges, lighter force can be applied to the probes, and plating damage can be avoided. The device also is constructed to avoid int...

A carton loading system has a carton carrier movable along a carton carrier support track driven by a continuous conveyor. The continuous conveyor has a first path segment in which the continuous conveyor drives the carton carrier along the track while a carton is placed into the carton carrier from a carton storage magazine by a carton transfer device. The continuous conveyor also has a second segment with a first portion arranged such that the conveyor is disengaged from the carton carrier to ...

Composite particles suitable as conductive filler for electrically conductive compositions which can be used as gaskets, caulking and plastics, for example. The compositions are, useful as EMI shielding and electrostatic charge dissipation materials. Methods of making and using the foregoing are also covered.

A system stores criteria specified by a funder relating to trade transactions for buyers and sellers. The system compares the criteria with a proposed purchase order to determine whether the system can generate a payment guarantee on behalf of the funder for the buyer to the seller. The system also compares subsequent documents relating to an original purchase order with the original purchase order to ensure that the terms of the purchase order are properly fulfilled. When the appropriate condit...

A method for depositing continuous cohesive, non-granular tightly adhering deposits on a substrat by using a rotating fibrous transfer means; deposit starting material is a small particle materials such as diamond powder; or powders of complex materials such as superconducting materials such as of the Y--B--C--O type; discrete deposits may be made and thereafter built-up on the substrate.

The invention relates to a method of production of ultradispersed diamond which can be used for the production of abrasive materials, more particularly, this method relates to production of fine diamond powder by explosive means.
