Abstract: Methods and apparatuses for attaching metal stencil foils to screen mesh using thermoplastic materials. Mechanical, rather than adhesive, attachment of metal stencil foils to screen mesh is accomplished by melting thermoplastic material so as to encapsulate portions of metal stencil foils and screen mesh resulting in faster, less expensive, and more durable bonding.

Abstract: In an embodiment of the present invention, a charge voltage is coupled between the positive and negative terminals of a rechargeable battery, to charge the battery. The charge voltage is disconnected for a predetermined relax time period. A rechargeable battery voltage is present between the positive and negative terminals of the battery during the relax time. The battery voltage is measured and compared to a predetermined target voltage that is associated with a sample time. The comparison is then used to determine if the battery is charged.

Abstract: This invention is a clamping strip attached to a flexible sheet, such as screen printing fabric, that is shaped to enable it to lock into a channel. The strip comprises a first and a second leg joined to each other at an approximately right angle. The first leg is of a size so as to position into the recess on one side of the channel leaving enough room for at least one thickness of the flexible sheet. The second leg is of a size so as to position within the channel at the same time as the first leg is positioned. The flexible sheet is affixed to the strip and wraps around the first leg inside the recess and continues over a rounded edge above the recess. With the strip and attached flexible sheet positioned into the channel with the flexible sheet wrapped over the rounded edge, a pulling or tensioning of the flexible sheet will cause the strip and flexible sheet to become locked in the channel.
