Abstract: An automated drafting system particularly suitable for drafting textile strands of sliver is provided. The automated drafting system includes a synchronous drive sliver drafting roller system utilizing toothed gears in the preferred embodiment operatively connecting a pair of drafting rollers with one of the rollers being directly driven by a motor to thereby cause identical rotation of both rollers. The automated drafting system also includes a system for securing and pressuring together upper and lower sliver drafting rollers wherein the lower roller of a pair of drafting rollers is preferably maintained in a fixed but rotational position while the upper roller of the pair is pressured towards the lower roller and controllably restricted as to both horizontal and vertical movement during the drafting process.

Abstract: A system for packaging integrated circuit components including a ball grid array substrate with a plurality of solder balls coupled to the substrate. A semiconductor device is mounted on the substrate and electrically coupled to the solder balls. One or more terminals are coupled to the substrate and electrically coupled to said semiconductor device. A detachable module contains auxiliary component, such as a data acquisition device, a wireless communications device, an output device or driving devices for a clock circuit. The module comprises a body portion for containing the component and one or more electrical connectors for mating with respective terminals to hold the module to the substrate and to electrically couple the component with the semiconductor device.

Abstract: A table shuffleboard has a rectangular table top with a divider rail down the center of the table separating the top into two playing courts along a substantial length of the tabletop. A crossover opening at a remote end from the players is provided to enable a sliding game piece or puck to be passed from one court to another, so that players can slide the puck and bank the puck against cushions from one court to the other for scoring during playing a game. The center divider rail includes cushions along its length for rebounding a puck, and the scoring areas are arranged to take into account the skill needed for banking shots in order to obtain high scores. A gate pin blocking arrangement is provided to prevent play when the device is used as a coin operated game.

Abstract: A modular calculator system using interchangeable input modules and output modules provides several different calculators using the same output display components to avoid expensive duplication of parts. The input module contains the calculator keyboard and program-control circuits which establish predetermined calculator functional capabilities, such as basic arithmetic or scientific functions. The output module houses and drives a printer and visual display components. Data from the input module is communicated serially over a single line to the output module so that a single reliable and inexpensive electrical connection may be used. An overlapping flange mechanical coupling physically connects the modules to form a combined unitary calculator housing.
