Title: Process and apparatus for reducing electrode wear in a plasma arc torch
Inventor: LUO LIFENG
IPC: B23K10/00
Filed: 1991-04-23
Abstract: ABSTRACT OF THE DISCLOSURE           A process and apparatus for reducing wear of an electrode in a plasma arc torch involves altering the gas flow in a plasma chamber surrounding the electrode immediately before and continuing after cutting of the current that sustain the arc.  The altering includes closing off the gas flow upstream of the chamber, switching from a swirling flow to a radial/axil flow through the plasma chamber, reducing the arc current level in conjunction with either of the above, and venting the plasma chamber to rapidly change the gas flow and pressure in the chamber.          The interval is sufficient to reduce electrode wear, but short enough that the arc remains stabilized until cut-off.  In the flow stop mode, a solenoid valve is placed on an inlet tube for the plasma gas.  Flow altering also occurs on start up.  A gas preflow is established prior to pilot arc ignition.  On transfer, the flow increases to its full operating value in conjunction with  an increase in the arc current.  The preflow can be axial, or partially axial.          Also, the type or composition of the gas used in the preflow and in the operating flow can change during the start up from a less reactive to more reactive gas.

IPC: H04H20/33
Filed: 1992-04-08
Abstract: Afin de permettre qu'un spectre de fréquences déjà occupé soit utilisé pour la transmission radio d'un train de données sans brouiller les services qui y sont déjà établis, un certain nombre de porteuses RF modulées avec le train de données sont transmises soit dans l'intervalle de fréquences séparant deux services FM à fréquences adjacentes au même endroit, soit dans les gammes de fréquences libres aux deux extrémités d'un service FM, en évitant d'occuper ses fréquences nominales. Comparativement au niveau de la porteuse RF du service FM à fréquences adjacentes ou du service FM médian, le niveau desdites porteuses RF est sélectionné de façon à être assez bas pour permettre un rapport signal-bruit suffisant pour la réception FM du ou des services FM. De plus, le niveau mentionné est sélectionné de façon à être assez élevé pour assurer l'immunité au bruit provenant de services FM plus éloignés utilisant la gamme de fréquences ou l'intervalle de fréquences destinés auxdites porteuses RF. Le train de données modulant les porteuses RF bénéficie d'une protection accrue contre les erreurs du fait qu'il possède une immunité suffisante au bruit provenant du ou des services FM à fréquences adjacentes ou du ou des services FM médians.

Abstract: ABSTRACT OF THE DISCLOSURE          A system for securing a plurality of tape pancakes 12 includes a compressible core support 24 on which the pancakes 12 can be mounted.  An interior rod 26 having a head 28 fits and is received within the core support 24.  A nub 34 on the inside surface 36 of the core support 24 engages a groove 38 on the outside surface 40 of the interior rod 26 to provide a threaded engagement between the interior rod 26 and the core support 24.  Rotation of the interior rod 26 within the core support 24 after the head 28 contacts the end of the core support 24 provides an axial compression load onto the core support 24 to hold together the pancakes 12.  This axial compression also expands the baffles which contact and tighten against the inside of the tape pancake cores and provide a radial force to secure the pancakes 12 in place.
