Abstract: In a device (5) for the manufacture of a quartz glass crucible (2), one section (14, 15) of a wall (13) of the rotating quartz glass crucible (2) is heated at one time by means of at least two electrode arrangements (7, 8) distributed uniformly at the circumference of the quartz glass crucible (2) and generating a first and another electric arc. By providing several electrode arrangements (7, 8), the cooling-down phase of the sections (14, 15) until their reaching the subsequent heating zone (11, 12) can be shortened, and thus an undesirable high temperature difference of the wall (13) can be avoided. Moreover, the required thermal output of each individual electrode arrangement (7, 8) can be reduced, so that evaporation phenomena and connected bubble formation can be reduced. In addition to the higher quality that can be reached in this way, the duration of the manufacturing process is reduced.

Abstract: A method is provided for identifying offsets of accelerometers integrated into hard disk drives. More specifically, often, disk drives employ accelerometers that constantly monitor the acceleration felt by the disk drive. Once the accelerations are less than a predetermined threshold, a free fall event is identified and an actuator arm that is generally positioned above the disk is placed in a safe location prior to impact. Accelerometers must be calibrated prior to use such that their inherent errors are identified and factored into the algorithm that identifies free fall. The method provided herein allows for the 0 g offset to be monitored without having to reorient the device being tested, thus saving time and money.

Abstract: A smoke sensing device for internal combustion engines comprises an electrode assembly with a heated insulator, a high voltage spark system, a voltage attenuator and a signal conditioning system. The electrode assembly is installed in an engine exhaust pipe so that the spark gap between the electrodes is exposed to the exhaust gas. A series of sparks is produced across the spark gap and the spark voltage is sensed and attenuated to produce a voltage signal.

The heated insulator burns off carbon deposits on the insulator surface. The repetitive sparks keep the electrode surfaces free of carbon deposit build-up.
