Title: Apparatus for detecting arcing faults and ground faults in multiwire branch electric power circuits
Inventor: ELMS ROBERT TRACY
IPC: H02H3/05
Filed: 1998-09-28
Granted: 2006-04-04
Abstract: A multiwire branch circuit including two line conductors and a grounded, common neutral conductor is protected by a two pole circuit breaker connected to interrupt current flow in the two ungrounded line conductors. Three separate protection circuits provide arc fault protection for each of the ungrounded line conductors and ground fault protection for all three conductors. The arc fault detectors use the bimetal of the thermal-magnetic trip device for the associated line conductor, and therefore, are individually referenced to the associated line voltage. Hence, the outputs of the arc fault detectors are electrically isolated from each other and from the output of the ground fault detector, but operate a common trip circuit to open the two pole circuit breaker. The arc fault detectors have separate isolated power supplies. The ground fault detector is powered by a supply which is energized if either of the ungrounded line conductors is energized.

Abstract: A jet for use in spas and hydrotherapeutic reservoirs having a first set of nozzles aligned in a plane at the water entrance side of the jet and a second set of nozzles aligned one-to-one with the first set of nozzles at the water exit side of the jet. A chamber separates the two sets of nozzles and includes a slot which is used to introduce air into the fluid stream. The amount of air introduced into the chamber is controlled by the user by rotating the jet within its housing from a maximum air intake position to a "no-air" intake position, air being introduced through a slot surrounded by a rectangular seal structure. A housing is provided to mount the jet within the wall of a spa comprising a rear wall mounting, an end cap, and a front wall mounting. Water is introduced to the multiple jet structure via a single horizontal water inlet. The servicing of multiple jets by the single water inlet and air line improves plumbing reliability and further reduces labor by minimizing the number of plumbing joints.

Abstract: A nurse adapter mechanism for an agricultural seeding implement converts an air seeder meter box into a nurse inductor box to convey seed particles to the singulator of a planting mechanism. The nurse adapter mechanism is detachably mounted on the meter box of the air seeder to receive a supply of seed particles therefrom and utilizes the normal air flow for the metering mechanism to effect a nursing of seed particles to a planting mechanism. The nurse adapter mechanism diverts the stream of air into engagement with a pile of seed particles and induce the entrainment of the seed particles for conveyance thereof to the remote planting mechanism. A partition wall divides the nurse induction mechanism into a seed side and an air side. The seed side receives the supply of seed particles from the hopper and allows the seed to pass through a passageway into the air side for engagement by the stream of air. Divider walls are provided to isolate each discharge tube from the other discharges tube so that the planter mechanisms can provide a continuous supply of seed particles. The discharge tubes pass through the seed side of the nurse adapter mechanism in a stacked pair, modular configuration with the respective discharge tubes being adequately separated to permit the passage of seed particles therebetween.

Granted: 2006-10-10
Abstract: A printer is provided which reliably detects front and back sides of a print medium and the print data to be printed to the respective sides, and automatically prints print data to the correct side of the print medium. A print command interpreter 203 interprets a print command received from the host device to determines the print medium side indicated by the print command for printing associated print data.  An inserted side detecting means 207 detects which side of the print medium inserted to the printer is facing a particular direction. Control units 204 and 208 print the print data when the print medium side detected by the print command interpreter 203 and the print medium side detected by the inserted side detecting means 207 are the same. Data can thus be printed to a desired specific side of the print medium because the printer 10 can reliably print to the print medium side specified by the host 220.

Granted: 2009-03-24
Abstract: A high intensity ion source for a mass spectrometer is provided having system dimensions and parameters which cause the Taylor cone of a liquid charge stream to pass through an aperture in an lens into a low pressure chamber without substantially desolvating. A capillary tube having an outlet diameter on the order of 50 micrometers is located in an ion source chamber which is maintained at close to atmospheric pressure. The outlet of the capillary tube is positioned at a distance on the order of 250 micrometers from the aperture of the lens. The low pressure chamber can be maintained at a pressure on the order of 13 pascals. With a suitable applied field, a Taylor cone ion stream is formed and passes through the aperture in the lens into a low pressure chamber without substantially desolvating. Substantial desolvation of the liquid charge stream can be later accomplished through the application of heating techniques within the low pressure chamber.
