Abstract: A fastening tool for driving a fastener into a workpiece is described herein. The fastening tool includes a contact trip, a magnet, and a magnetometer. The contact trip is disposed at a first end of the fastening tool and is configured to move toward a second end of the fastening tool opposite of the first end when the contact trip engages the workpiece. The magnet is configured to generate a magnetic field. The magnet is coupled to the contact trip such that movement of the contact trip causes the magnet to move. The magnetometer is configured to detect a change in the magnetic field generated by the magnet when the magnet moves relative to the magnetometer and, based on the detected change in the magnetic field, to generate a signal indicating when the contact trip engages the workpiece.

Abstract: An electric fastener driving tool assembly can include a driver designed to drive a fastener into a workpiece. The driver can reciprocate along an axial driver path between an extended position and a home position. A home position sensor can be located laterally adjacent the axial driver path. The home position sensor can be located to sense the presence of the driver in the home position when a lateral distance between the driver and the sensor changes.

Abstract: Disclosed is a process/system for the removal of metal chloride impurities from a titanium tetrachloride stream. The metal chloride impurities are removed through contact of the titanium tetrachloride stream with an alumino-silicate material, which can be selected based on certain properties of the alumino-silicate and based on the geometries of the impurity(ies) and the alumino-silicate.

Abstract: Disclosed is a process/system for the removal of metal chloride impurities from a titanium tetrachloride stream. The metal chloride impurities are removed through contact of the titanium tetrachloride stream with a sorbent material comprising a member selected from the group consisting of an alumino-silicate, activated alumina, ultrafine TiO2, and combinations thereof.

Abstract: A transistorized amplifier includes an active network having a succession of DC coupled transistors, a load resistor across which an output voltage is developed in response to current flowing through the active network and a voltage divider network for distributing an applied DC potential equally across the active network. Each stage in the active network is thereby allowed to operate over only a restricted voltage range, while yet operating cooperatively to control high voltages, using inexpensive low voltage rating components. The amplifier preferably includes at least two sets of active networks, load resistors and voltage divider networks, each set being responsive to a complementary input signal current to provide complementary output voltages useful in driving a pair of electrostatic deflection plates.
