Abstract: Apparatus includes a production tooling having a dispensing surface with a plurality of cavities and formed into an endless belt. An abrasive particle feeder dispenses shaped abrasive particles onto the dispensing surface and into the plurality of cavities. A resin coated backing receives shaped abrasive particles from the cavities of the production tooling at a deposit point. A detecting device detects a pattern transition zone as the production tooling moves in the direction of travel and provides pattern transition zone detection data to one or more controllers to control a speed of the production tooling and/or a speed of the resin coated backing as the detected pattern transition zone passes the deposit point to change a pattern density of the shaped abrasive particles in a portion of the resin coated backing corresponding to the pattern transition zone of the production tooling.

Abstract: An improved medical device reduces the loss of longitudinal length during expansion of a stent-graft from a compressed state to an expanded state. For example, the stent-graft is placed over a cover that provides resistance to expansion of the balloon during inflation, which reduces longitudinal compressing forces exerted on the stent-graft.

Abstract: A system and method for producing an abrasive article includes a production tool configured to provide shaped abrasive particles to a resin coated backing. A first end and a second end of the production tool are spliced together to form a spliced area. The production tool includes a dispensing surface that includes a plurality of cavities formed between the first end and the second end and configured to receive and hold the shaped abrasive particles. The resin coated backing is configured to receive the shaped abrasive particles from the dispensing surface of the production tool and configured to receive further shaped abrasive particles to fill gaps in the shaped abrasive particles caused by an absence of the plurality of cavities in the spliced area.

Abstract: A locking device for maintaining electrical connection in spade-type connectors. The locking device has two interconnecting parts, each of which positively receives a terminal of the spade-type connector. The locking device includes means which prevent the lateral and translational movement of the spade connector terminals therewithin, so that they are held in ready alignment for connection.
