| 20100043208 | METHOD FOR FORMING LAYERED HEATING ELEMENT FOR GLOW PLUG - A monolithic, multi-layer heating element forms the high temperature tip of a glow plug assembly. The heating element includes a conductive core which is surrounded by an insulator layer, which in turn supports a resistive layer. An optional conductive jacket can surround the resistive layer. These layered components are pre-formed in prior operations and then assembled one into the other to form a precursor structure. The precursor structure is transferred to a die, where it is compressed to form a so-called green part having dimensional attributes proportional to the finished heating element. The individual layers remain substantially intact, with some boundary layer mixing possible to enhance material-to-material bonding. The green part is sintered to bond to various materials together into an essentially solid mass. Various finishing operations may be required, following which the heating element is assembled to form a glow plug. | 02-25-2010 |

| 20080223185 | ATTACHMENT WITH COLLAPSIBLE FRONT END FOR PORTABLE SCREW DRIVING TOOL - An attachment for a portable hand-held screw driving tool is provided for use with collated strips of screws. The front portion of the attachment is movable to a great extent, to thereby allow the tool to drive screws almost directly at the corner of two walls. A front “nose piece” is pressed against one of the walls, which causes the nose piece to move rearward “into” the remainder of the tool, in a “first stage” of movement. A screw is indexed to its drive position, and a drive bit is abutted against the screw head during this first stage. The nose piece is pressed further into the tool, which also causes a “feed tube” to move rearward “into” the remainder of the tool, in a “second stage” of movement, which rotates the screw as it is emplaced into the wall. | 09-18-2008 |
| 20120073410 | DETENTED ADAPTER INTERFACE FOR SCREWDRIVER TOOL ATTACHMENT - An attachment is mated to a power screwdriver by use of an adapter that is first fixed onto the screwdriver. The attachment includes an automatic fastener driver that receives a collated strip of fasteners, and drives them into a working surface. The attachment is mated to the adapter; the attachment contains a radial type of mechanical coupling that can be rotated without dismounting the attachment from the power screwdriver. In this manner, the angular orientation between the attachment and the power screwdriver can be changed “on the fly” by the user. This combination allows the user to keep his or her hands at their operating positions throughout this procedure, thereby allowing the user to re-commence using the combination tool quickly after readjusting the operating angle. | 03-29-2012 |
