Title: Grill assembly for a cyclone-type dust collecting apparatus for a vacuum cleaner
Inventor: OH JANG-KEUN
IPC: H01L35/16
Filed: 2002-08-07
Abstract: A grill assembly for a cyclone-type dust collecting apparatus for a vacuum cleaner reduces the amount of contaminants moving toward a body of the vacuum cleaner through a grill, and also allows easy removal of contaminants from the grill. The grill assembly includes a grill body having an open upper end; a plurality of blades formed along an outer circumference of the grill body at predetermined intervals from one another to define passages interconnected with the air outlet; and a fine contaminant blocking member mounted within the grill body at a position corresponding to the passage of the grill body to filter out fine contaminants that pass through the passage. The grin body includes a first body portion supported on the air outlet of the cyclone body and having a through hole, and a second body portion on which the plurality of blades are arranged, the second body portion being removably connected to the first body portion by connecting means. Reversal of contaminants through the passage of the grill body is made difficult, and accordingly, the amount of contaminants entering into the cleaner body can be reduced. Also, a user can remove the contaminants from the grill easily, after he/she simply separates the second body portion from the first body portion.

Abstract: L'invention concerne une liaison de communication optique hybride sans fil et une liaison de transmission par radiofréquence (RF) utilisant des trajets optiques et RF à espace libre parallèles destinés à transmettre des données et des informations de commande et d'état. La liaison optique fournit le trajet primaire pour les données, et la liaison RF fournit un trajet concurrent ou de réserve pour les données réseau, de même qu'un trajet fiable et primaire pour les informations de commande et d'état. Lorsque les conditions atmosphériques dégradent la liaison optique au niveau de l'emplacement où la transmission de données optiques échoue, la liaison de communication hybride passe en liaison RF afin de conserver la disponibilité des communications de données. La commutation peut se produire automatiquement, en fonction d'une analyse de la qualité du signal optique communiqué par l'intermédiaire du trajet optique.

Title: Extruded foam product with reduced surface defects
Inventor: MILLER LARRY M
IPC: C08L23/06
Filed: 2001-02-27
Abstract: The present invention generally relates to processes for preparing extruded foam products and more particularly to a process for producing such products wherein surface defects are minimized.  There has been a movement to replace conventional halo-carbon blowing agents in favor of purportedly more environmentally safe halo-carbon free blowing agents such as carbon diox-ide, nitrogen, argon, water, air, nitrogen, and helium. However, these halo-carbon free blowing agents, in particular carbon dioxide, have higher foaming rates and higher volatility leading to greater surface defects in the extruded foam. The present invention employs polyethylene wax to reduce or eliminate the occurrence of surface defects where halo-carbon free blowing agents are employed in an extruded foam manufacture process. The polyethylene wax containing extruded foam products of this invention are characterized by a generally smooth substantially defect free surface and contain a majority of closed cells which are free of any trapped halo-carbon blowing agents.

IPC: G08G5/04
Filed: 2001-07-10
Abstract: Improved methods and systems for detecting self-alerts from upload messages in a TIS system to thereby eliminate the likelihood of TIS self-alerts appearin g on CDTI displays. The present invention determines whether a self-alert was present in a previous traffic information uplink to determine whether a targ et in a current information uplink is real. Using a weighting algorithm, typically a fuzzy logic algorithm, a system in accordance with the present invention can distinguish between targets in consecutive radar sweeps to identify self-alerts. If the self-alert was not present in previous uplinks,  then the system removes the self-alert from subsequent views on the CDTI. Thus, the present invention provides an improved visual display system for pilots and air traffic controllers.

Title: Vehicle closure anti-pinch assembly having a non-contact sensor
Inventor: DANIELS ANDREW R
IPC: E05F15/00
Filed: 2001-08-03
Abstract: An anti-pinch assembly is used in combination with a closure device of a motor vehicle. The closure device includes a closure panel, i.e., a windowpane or door, and a motor for moving the closure panel between an open position and a closed position. In the closed position, the closure panel covers an aperture, i.e., a window or door opening, of the motor vehicle. The anti-pinch assembly includes a position sensor that is disposed adjacent the motor or the closure device. The position sensor generates a position signal indicative of the position of the closure panel. A capacitive sensor measures the capacitance of a field extending through the aperture. The capacitive sensor generates a signal therefrom. A controller is electrically connected to the position and capacitive sensors. The controller receives the position and capacitive signals and transmits a signal to the motor to prevent the motor from moving the closure panel toward the closed position when the output signals deviates from a series of predetermined values for more than a predetermined period of time.

The case is preferably made of a relatively flexible transparent plastic material. The disc is unclipped by pressing the thumb on the middle of the centering element while simultaneously exerting a flexure with the tip of the finger on the rear side of the periphery of the case.

Abstract: The invention relates to a pallet container (10) comprising a thin-walled inner container (12), preferably consisting of a thermoplastic plastic, for storing and transporting liquid or free-flowing filling materials, a tubular framework of metal bars, which closely surrounds the plastic container (12) and acts as a support shell (14) and a base pallet (16), on which the plastic container (12) rests and to which the support shell (14) is connected in a fixed manner. In order to receive official certification, the pallet container (10) must undergo various certification tests, such as a compression pressure test, interior pressure test or a drop test. During the drop test, the vertical lattice bars (20) are often wrenched out of or shear away from their anchorage on the base pallet (16). According to the invention, to prevent such detrimental effects, the tubular bars (18, 20) of the support shell (14) are provided with specific features in the event of the container falling, said features allowing a plastic deformation of the support shell (14) at specific predeterminable points, whilst preventing the individual tubular bars (20) from shearing or being wrenched out of their anchorage. According to one embodiment of the invention, the features allowing the plastic deformation of the support shell take the form of a flexure point coupled with a reduced cross-section of the bars.
