Patent CA-2215021-A1 (CA)
Inventor: MOSSBERG THOMAS W
IPC: H04B10/524
Filed: 1996-03-08
Abstract: Apparatus and methods are disclosed for spatially routing an optical pulse (data pulse) of an electromagnetic radiation and containing a specific address temporal profile and possibly additional data. Routing generally involves a unit of active material (AM) that is programmed using one or more input beams or pulses (e.g. K2) of the electromagnetic radiation providing address (i.e., waveform-discriminating) and directional (i.e., pulse routing) information to the active material. During programming, a spatial-spectral grating is created by optical interference on or in the active material of the input pulses encoding the address and directional information pertinent to data pulse. Whenever a data pulse, encoding a temporal profile that is substantially similar to temporal profile of the address, interacts with the grating in or on the active material, the active material produces an output pulse (KS) that propagates in a direction, relative to the material, corresponding to the directional information provided during programming.

Patent CA-2224362-A1 (CA)
Inventor: STOCKWALD KLAUS
IPC: H05B41/288
Filed: 1996-07-18
Abstract: The invention pertains to a method for operating a lighting system with an incoherently-emitting radiation source, in particular a discharge lamp that emits UV, IR or visible-range radiation, by means of dielectrically inhibited discharge, and to a lighting system suitable therefor. The electrodes, which are arranged side by side and separated from each other and the interior of the discharge vessel by dielectric material, are alternatingly connected to the two poles of a voltage source. In operation the voltage source supplies a series of voltage pulses separated by quiescent periods. According to the invention, this produces inside the discharge vessel a spatial discharge which in the regions between electrodes of different polarity is at a distance from the surface of the inside wall of the discharge vessel. Substantial advantages are less stress on the wall of the discharge vessel and greater efficiency in generating radiation.

Title: Ensemble d'articulation ameliore et ensemble d'adaptation de doubles toits pour tentes a armatures parapluie pliantes, et armatures correspondantes
Inventor: ALLEGRETTO PAUL V
IPC: E04H15/28
Filed: 1996-08-01
Abstract: L'invention concerne un ensemble d'articulation modifié pour tentes pliantes. Cet ensemble est modifié comme suit: un guide d'entrée d'axes coniques sur un premier élément de l'ensemble d'articulation permet d'engager correctement l'extrémité de l'axe sur un second élément dudit ensemble dans la cavité du premier élément. L'ensemble modifié permet donc de guider l'axe dans la cavité malgré la torsion ou le tordage de l'armature intervenant au moment du montage de la tente en raison de la flexibilité intrinsèque des matériaux constitutifs d'une armature de tente et de la tendance chez l'usager à appliquer par inadvertance des forces obliques par rapport à la verticale, ce qui résulte d'une pression des mains lorsque l'élément d'articulation inférieur est déplacé vers l'élément d'articulation supérieur. De préférence le guide d'entrée de l'axe conique fait partie intégrante de la surface inférieure de l'élément d'articulation supérieur ou bien de la surface supérieure de l'élément d'articulation inférieur. A titre facultatif, on peut encore modifier l'ensemble d'articulation en y ajoutant, dans l'élément supérieur sus-mentionné ou sur celui-ci, une structure pouvant accueillir un ensemble d'adaptation de double-toit. Cette structure peut être une matrice creuse ayant une implantation centrale et s'étendant depuis le centre de la surface inférieure de l'élément d'articulation supérieur verticalement par le centre de cet élément depuis sa base vers le sommet du guide d'entrée de l'axe conique, ou bien un manchon ou une cavité support pour l'axe au sommet du guide d'entrée de l'axe conique ou bien encore un réceptacle d'adaptateur de double-toit ayant une implantation centrale dans la surface supérieure de l'élément d'articulation supérieur ou bien aussi un axe faisant saillie centralement et verticalement depuis la surface supérieure dudit élément. On décrit par ailleurs un ensemble d'adaptation de double-toit qui permet de monter un double-toit, le cas échéant sur une tente à armatures parapluie pliantes. Cet ensemble comprend un seul élément d'articulation et une pluralité de bras. En position centrale sur la surface inférieure de l'élément d'articulation de l'ensemble considéré, on trouve un dispositif de fixation de l'adaptateur de double-toit à l'élément d'articulation supérieur modifié de l'armature de la tente pliante. Le dispositif de fixation de l'adaptateur est conçu pour coïncider avec la structure dans laquelle il est introduit sur l'élément d'articulation supérieur de l'armature de la tente.
