Title: Discharge lamp with dielectrically impeded electrodes
Inventor: EBERHARDT ANGELA
IPC: H01J65/00
Filed: 1999-05-11
Granted: 2008-05-06
Abstract: The invention relates to a discharge lamp suitable for operation by dielectrically impeded discharge and comprising electrodes arranged on the wall of the discharge vessel. Said lamp has at least one dielectric layer which covers at least a part of the electrodes and optionally also at least part of the discharge vessel wall. A luminescent and/or reflecting layer is placed on the at least one dielectric layer. According to the invention at least the dielectric layer arranged directly beneath the luminescent and/or reflecting layer consists of a glass solder, especially a sintered vitroceramic material, whose viscosity is irreversible in relation to temperature. This prevents the dielectric layer from renewed melting during the production process and therefore the porous reflective and/or luminescent layer placed on the dielectric layer from cracking.

Patent CA-2312356-C (CA)
Title: Dross collecting zinc pot
Inventor: MENEICE DAVID J
IPC: C23C2/00
Filed: 1998-10-29
Granted: 2004-06-29
Abstract: A zinc-coating pot for galvanizing steel strip has two levels along its bottom surface. The first, shallower level is located under a coating roll, thereby creating an area where the molten zinc-coating metal flow rate is relatively high. Dross particles remain suspended and do not accumulate on the bottom of the zinc-coating pot in this region. A  second, deeper level is located to one side of the first level. This second level creates a space wherein the molten metal flow rate is less than the terminal velocity of the dross particles. This encourages sedimentation of the dross particles in this region. It provides an accumulation area for any bottom dross to be later removed by a dross removal mechanism, such as mechanical scoops or by pumping, without interruption to the coating process.

Abstract: A roof vent device formed from upper and lower outer surfaces sized to define a generally rectangular configuration having a linear axis. A tapered matrix is positioned between the outer surfaces, the taper being directed in a direction perpendicular to the axis to define a thin linear edge and a thick linear edge along the outer edges of the configuration that are parallel to the axis and tapered linear edges along the outer edges of the configuration that are perpendicular to the axis. The tapered matrix has a gap located proximate the middle of the tapered linear edges and extending generally over the linear axis of the outer surfaces. The gap defines an entrance for an air to vent air from beneath the roof ridge out the thick linear edge. The gap further provides a pivot point about which the configuration folds to conform to a roof pitch having a predetermined angle. In one embodiment the matrix is tapered from one outer edge to the gap and the remaining portion of the matrix is generally level. In the preferred embodiment, the taper extends from one linear edge to the other. In a preferred embodiment, a baffle extends out from the thick linear edge and is shaped to deflect outside air away from the thick linear edge without inhibiting air flow out of the linear edge from the air tunnel entrance.

Abstract: En général, les éoliennes présentent un organe d'entraînement actif servant à les orienter en fonction du sens du vent. Cet organe d'entraînement fait tourner la nacelle de l'éolienne de sorte que les pales du rotor soient orientées dans le sens du vent. Cet organe d'entraînement nécessaire pour l'orientation est en règle général un organe d'entraînement azimutal se trouvant, avec les paliers azimutaux correspondants, entre le sommet de la tour et la nacelle. Dans les petites éoliennes, un organe d'entraînement réglable est suffisant, tandis que les éoliennes, de plus grande taille, sont équipées de plusieurs organes d'entraînement azimutal. L'invention vise à améliorer l'organe d'entraînement azimutal pour les éoliennes, de façon à créer un organe d'entraînement azimutal de conception simple, à assurer une répartition des charges homogène pour chaque organe d'entraînement azimutal et à éviter des variations de couple indésirables des organes d'entraînement individuels. L'invention concerne une éolienne comportant une nacelle dans laquelle est logé un rotor présentant au moins une pale, et comportant une unité servant à déplacer la nacelle de manière à placer le rotor dans une orientation voulue, dans le sens du vent. L'élément d'entraînement de cette unité de déplacement est un moteur asynchrone triphasé qui est alimenté avec un courant triphasé pour déplacer la nacelle, et qui est alimenté, partiellement ou totalement, avec un courant continu pendant une période d'arrêt de la nacelle.

Abstract: A medium access protocol which adjusts number of contention slots in a variable length frame and superimposes a variable window structure over the frame structure. The number of contention slots (24) in a frame (28, 30) is changed on a frame by frame basis by determining if a collision occurred in any contention slot (44). If not the contention slot is removed (48) and if so, the number of slots is increased (52). In high traffic situations, if the average load is greater than a threshold (107, 120) the number of frames in a window is increased (130). If the load drops below the threshold (120), the number of frames per window is decreased (124).
