Abstract: A heater effectively uses a current controlled fan motor in series with a resistance heating arrangement. The fan motor preferably is wound with a gau ge of wire to appropriate for the relatively high current provided to the fan motor. This arrangement is effectively used to adjust the fan speed to match the heat output when the heating arrangement has variable heat output. More desirable operating characteristics are achieved without increasing costs an d fan motor manufacturing savings are realized. The portable heater preferably produces heat at different outputs and the current used to power the resistance heating arrangement is used to power the fan motor.

Abstract: This invention identifies anomalies in a data stream, without prior training, by measuring the difficulty in finding similarities between neighbourhoods in the ordered sequence of elements. Data elements in an area that is similar to much of the rest of the scene score low mismatches. On the other hand a region that possesses many dissimilarities with other parts of the ordered sequence will attract a high score of mismatches. The invention makes use of a trial and error process to find dissimilarities between parts of the data stream and does not require prior knowledge of the nature of the anomalies that may be present. The method avoids the use of processing dependencies between data elements and is capable of a straightforward parallel implementation for each data element. The invention is of application in searching for anomalous patterns in data streams, which include audio signals, health screening and geographical data. A  method of error correction is also described.

Abstract: L'invention porte sur un dispositif bloqué à l'état ouvert destiné à un clapet. L'outil vient en contact avec le corps de la vanne de sécurité de subsurface et fait tourner le clapet pour amener celui-ci en position ouverte, sans déplacer le tube d'écoulement. La base du clapet est de préférence maintenue par application d'un cisaillement sur un filetage et comporte une gorge permettant l'engagement de l'outil. L'outil effectue un repêchage sur la base du clapet pour appliquer un cisaillement sur le filetage et pousser le clapet maintenu ouvert dans une gorge de retenue. Un outil de pénétration peut éventuellement être aussi raccordé de manière que, en un seul déplacement, le clapet puisse être bloqué à l'état ouvert, ce qui permet aussi d'accéder au système de commande sous pression. Le cisaillement appliqué au filetage permet au ressort du tube d'écoulement de solliciter le clapet maintenu ouvert dans sa gorge de retenue.

Title: Arc fault circuit breaker and apparatus for detecting wet track arc fault
Inventor: SCHMALZ STEVEN C
IPC: H02H1/00
Filed: 2005-05-20
Granted: 2013-01-08
Abstract: An apparatus includes a first circuit detecting when an absolute value of a current signal is less than a first predetermined value and outputting a signal after a first time period. A comparator compares that signal to an envelope of a rectified current signal, in order to provide an output with a plurality of pulses that persist for a relatively longer time for a relatively small value of the envelope, and persist for a relatively shorter time for a relatively large value of the envelope. A second circuit enables the comparator output if the rectified current signal exceeds a second predetermined value, and disables the comparator output after the rectified current signal is below the second predetermined value for a second time period. A third circuit accumulates the pulses and outputs a signal representative of a wet track arc fault.
