Abstract: A magneto-electrophoretic medium that can be globally and locally addressed and erased. The medium provides a writeable display with no perceivable lag and the ability to write and erase with only minimal power requirements. In particular, the magneto-electrophoretic medium can be erased by providing a subthreshold electric stimulus and supplementing a second non-electric stimulus that disturbs the written state and allows the magneto-electrophoretic particles to return to their original state.

Abstract: A stylus for interacting with a magnetic writing medium, such as a magneto-electrophoretic media containing magnetic particles that can be switched electrically in the same way as a conventional electrophoretic display: e.g., between white and black states with the capability of also attaining stable intermediate states of gray. The stylus includes a magnetic sphere and a metal cylinder aligned in the tip.

Abstract: A REST-based event distribution system is described, with particular applicability to the distribution of distributed filesystem notifications over a high-latency best-effort network such as the Internet. In one embodiment, event channels are mapped to URL spaces and created and distributed through the use of HTTP POST and GET requests. The system is optimized for short polling by clients; an event history is maintained to buffer messages and maintain the idempotence of requests. In another embodiment, the events are registered as a SIP event pack allowing for the distribution of filesystem events.

Abstract: A dry lubricated wire drawing and cooling apparatus comprising a die holder supporting a pair of dies in coaxially aligned and axially spaced relation. The die holder and dies cooperate to define a cooling chamber through which cooling liquid is circulated and drawn wire is constrained to pass. A sensing device detects approach of a wire end and operates mechanism to shutdown the apparatus and expel cooling liquid from the cooling chamber before the wire end reaches the first one of the dies.

Abstract: A multiple stage wire drawing machine having a final stage draw block and a plurality of multiple step draw capstan assemblies each having a plurality of coaxial draw capstans of increasing diameter rotatably mounted on a drive spindle, driven at a fixed angular rate relative to the final stage draw block, and independently driven by the spindle through friction disc slip couplings at substantially the same slip drive torque.

Abstract: A multiple stage wire drawing system with a plurality of pivotal dancer pulleys, each operable for maintaining wire stock tension between stages and for feeding wire stock downwardly along a generally helical path from an upper guide pulley receiving wire stock from a preceding draw block to a lower coaxial guide pulley aligned for guiding wire stock to a succeeding die block. Each pivotal dancer pulley is mounted via a support rotor on a relatively short pivot arm and for rotation about an axis inclined to its pivot axis, and a toggle type linkage is connected to the dancer pulley support rotor for controlling the angular relationship of the inclined dancer pulley to the coaxial guide pulleys.
