Title: Electrical raceway assembly
Inventor: GUTGSELL DAVID R
IPC: E04B2/74
Filed: 1999-10-05
Granted: 2005-09-20
Abstract: An electrical raceway assembly for use with a structure is provided, comprising an elongated raceway engageable to the structure and having a length, a transverse base and a pair of opposite upstanding sidewalk extending along the length to define at least one channel configured for retaining electrical wires. A cover attachable to the raceway to occlude a portion of the channel is included. The cover includes an elongated face plate having an interior surface and an exterior surface. The cover is configured for snap fit engagement with the raceway. One end of the cover is rotatable, about a longitudinal axis of the raceway, between an open position in which a portion of a channel of the raceway is exposed and a closed position in which the other end of the cover is engaged to the raceway. A flange extends from one of the portions of the cover. The flange is relatively more flexible other elements of the cover and occludes an area behind the flange when the cover is attached to the raceway and the flange being elastically deformable to allow access to the area. In one embodiment, a living hinge is defined in the cover between the face plate and the rotatable end of the cover. The living hinge is elastically deformable to permit pivoting of the face plate relative to the rotatable end of the cover, thereby permitting greater access behind the cover.

Title: Systeme de regulation de soudure par resistance, au moyen d'une compensation d'impedance de la ligne
Inventor: BAILEY JONATHAN H
IPC: B23K11/24
Filed: 1999-01-25
Granted: 2007-10-09
Abstract: Dans ce système à régulateur de soudure commandé en phase, on utilise un modèle interne de ligne de soudure et d'impédance de la charge, ainsi que de tension d'entrée de soudure, en circuit ouvert, pour développer une séquence angulaire nominale d'amorçage, afin de conserver une séquence voulue de courant de soudure. Le régulateur de soudure calcule une séquence angulaire nominale d'amorçage d'après des modèles estimatifs d'impédance de la ligne, de tension de la ligne en circuit ouvert, un rapport estimatif entre le courant dans la charge et l'angle de conduction, ainsi que le rapport mathématique entre l'angle d'amorçage, l'angle de conduction et la puissance du circuit de la charge permettant l'exécution d'une séquence de soudure voulue, si les modèles sont exacts. Le régulateur de soudure utilise ensuite des valeurs mesurées reçues en temps réel pendant l'exécution de la séquence de soudure, afin de modifier l'angle d'amorçage nominal et mieux atteindre l'objectif voulu. Cette approche permet au régulateur de soudure d'exécuter rapidement la séquence de soudure voulue à l'aide de la charge réelle, tout en permettant de faibles gains de rétroaction, constituant ainsi un système de réponse rapide et précis qui n'est toutefois pas trop sensible.

Abstract: In a telecommunications system, such as a cellular radio telecommunications system, transmission information, such as modulation scheme selection information, coding information or power level control commands, is efficiently conveyed from the transmitter to the receiver without increasing the bandwidth requirements and without introducing additional transmission delays. This can be accomplished by employing a data symbol phase rotation technique, wherein a sequence of data symbols, for example, a sequence of training symbols used for estimating the propagation characteristics of a given channel, are phase-rotated in accordance with a phase rotation factor that uniquely corresponds to the information being conveyed to the receiver. At the receiver, the symbols are de-rotated until the receiver recovers the training sequence. This allows the receiver to determine the phase rotation factor used to rotate the symbols at the transmitter. This, in turn, identifies the corresponding transmission information.

Abstract: In manufacturing a moving web, such as a tissue sheet, the web is transported at very high speeds, often in an unsupported manner, which can result in unstable operations regarding handling and winding of the web. This is particularly true in the region between the creping blade and the reel for a lightweight, low modulus tissue sheet that is characteristic of a high-quality, soft tissue basesheet. To provide an improved means of controlling the tissue web during manufacture and to improve the manufacturing rate, an apparatus and method of stabilizing the moving web that incorporates a creping blade foil, one or more aerodynamic sheet stabilizing foils, and a roll foil in a specific relationship to each other is disclosed. This method has been shown to improve the stability of a moving tissue web, allow for a higher rate of operation, and enable the production of softer tissue basesheets.
