Title: Interpretation de spectres de masse de melanges d'ions a charges multiples
Inventor: ZHOU XIAO-GUANG
IPC: H01J49/00
Filed: 1991-12-12
Abstract: Un mélange chimique est acheminé jusqu'à un appareil de charge multiple où des ions à charge multiple sont formés. Les ions à charge multiple sont ensuite acheminés jusqu'à un spectromètre de masse (24) générant des données de spectre de masse/charge rapportant l'intensité à une plage de valeurs de masse/charge. Ces données de spectre de masse/charge sont transformées afin de générer des données de spectre de masse rapportant l'intensité à une plage de valeurs de masse. Ensuite, un ensemble de masses connues sont identifiées à partir des données de spectre de masse par association de chaque valeur d'intensité de sommet dans le spectre avec sa masse moléculaire. Alors, une liste de rapports de masse/charge pour chacune des masses identifiées est formée et stockée. Ensuite, une plage de rapports de masse/charge pour chaque valeur de masse des données de spectre de masse est calculée. Des données de spectre d'identification (52) sont ensuite calculées par affectation d'une valeur au spectre d'identification à partir de données de spectre de masse/charge: (1) pour des données de spectre de masse/charge correspondant à des masses connues, et (2) pour des données de spectre de masse/charge ne correspondant pas à des masses connues et ne correspondant pas à une valeur de la liste. Des valeurs de masses associées à des valeurs d'intensité de sommet (54) du spectre d'identification obtenu sont ensuite identifiées puis ajoutées à la liste des valeurs de masse connues. Ces étapes gérées par ordinateur (37) sont répétées afin d'identifier une pluralité de valeurs de masse.

Title: Vacuum belt drive train
Inventor: IDE RUSSELL D
IPC: A47L5/30
Filed: 1992-02-14
Abstract: A belt drive train particularly useful for driving the beater bar (30) of a vacuum cleaner. The drive train includes a driven shaft (27) preferably driven by a motor (20), a drive shaft (32) preferably connected to a beater bar and including a driven pulley (33), and an inelastic belt (140) coupling the drive shaft (32) to the driven shaft (27). Both the drive shaft and the driven shaft are supported on bearings. At least one of the bearing is mounted in a deflecting bearing mount (137) so that the shaft supported by the bearing can be moved relative to the housing (10). As a result of this construction, the drive shaft and the driven shaft can be moved closer to one another to allow the inelastic belt to be passed over the drive shaft and the driven shaft. The elasticity of the deflecting bearing mount then causes a belt tension sufficient to allow the drive shaft to drive the driven shaft through the belt. The drive train can also include one or more self aligning sleeve bearings (70) to compensate for the unbalanced belt tension force. The sleeve bearings include a shaft support surface (71), an outer periphery (73) and a deflecting element (72) supporting the shaft support surface on the outer periphery.

Abstract: The vehicle brake with brake cylinder bore insert (30, 130) comprises a cast disc brake cylinder (12, 112) which includes a bore (14, 114) into which the bore insert (30, 130) may be disposed.  The bore (14, 114) may have an opening (22, 118) at either one (20, 120) of the opposite axial ends for inserting the bore insert (30, 130). The insert has lock ribs (34) disposed about the perimeter (32) thereof, and at opposite axial ends a pair of perimeter extensions or crush ribs (36) which tightly engage the surface (21, 121) of the bore (14, 114) when the insert (30, 130) is disposed within the bore (14, 114). The insert (30, 130) has opposite flat sides (50) which permit an adhesive material to be disposed between the lock ribs (34) and the surface (21, 121) of the bore (14) in order to fix the insert (30) within the bore (14). The insert (30, 130) contains a central opening (39, 139) which may be of different diameters or shapes for receiving a piston (40) and seals disposed about the piston (40).

Title: Rotor of an electrical machine having an excitation current supply line
Inventor: HADITSCH WERNER
IPC: H02K9/00
Filed: 1992-11-09
Abstract: ABSTRACT OF THE DISCLOSURE          In large electrical machines,  the electrical connection between the excitation supply line (7, 8), which runs axially,  centrally in the rotor,  and the excitation winding conductors (4) in the winding over-hang (3) of the rotor is highly stressed electrically and mechanically. It must therefore be forced-cooled. Effective cooling can be achieved if a portion of the cooling  gas  from  the  cold  gas  chambers  is guided through special radial shaft holes (20) to the shaft axis and then radially outwards through or along the excitation supply line bolt (13) into the hot gas space (H) in the rotor winding overhang space.

Patent CA-2084841-A1 (CA)
Inventor: PELLEY KENNETH A
IPC: B05B15/04
Filed: 1992-12-08
Abstract: An apparatus and method for applying particulate powder material to a moving fibrous substrate is disclosed. The apparatus includes a volumetric dry material feeder for forming a continuous stream of particulate powder material. The continuous stream is then transmitted through a nozzle and exits at an outlet thereof. The nozzle is movable between a first and second position by a motion control. The motion control includes an adjustable differential gear box and an encoder for synchronizing the dispensing of powder at a predetermined location of the substrate. A flow separator is disposed beyond the outlet of the nozzle and intermediate of the first and second positions. In operation, the motion input drives the nozzle to oscillate between the first and second positions at a variable speed over each product cycle. As the nozzle crosses a plane of the flow separator, the continuous stream of particulate powder material exiting the nozzle is split into two intermittent streams of particulate powder material. The first intermittent stream is applied to a predetermined location of the moving fibrous substrate to form a layer of particulate powder material within a predetermined portion of the substrate. The second intermittent stream is recirculated back to the volumetric dry material feeder.

Title: Fluid mixing accessory
Inventor: MARTIN JEFF
IPC: B01F15/02
Filed: 1991-01-10
Abstract: A fluid mixing accessory comprising a mixing receptacle integrally formed with a funnel. The accessory is formed of a flexible material which is light-weight and disposable.      The measuring receptacle is a graduated cone for measuring the components of a mixture, such as the color, the hardener and the reducer of a paint composition. The funnel has an opening, which, depending on the nature of the fluid being mixed, may include a gauze or mesh to act as a strainer. The funnel and the measuring receptacle are joined by a connecting portion. Thus, once the fluid has been mixed in the mixing receptacle, the accessory is inverted so that the mixture runs from the receptacle, across the connecting portion and into the funnel which is positioned over a container. After the funnel has emptied, the entire device then can be collapsed and discarded. The funnel is collapsible for convenient shipping and storage.

Abstract: La présente invention porte sur un système décisionnel de recouvrement de signaux d'horloge comprenant des circuits qui servent à empêcher les verrouillages erronés et à accélérer l'acquisition des configurations de symbole connues. Le système de recouvrement de l'invention comprend au moins deux circuits de commande. Chacun d'eux a une largeur de bande effective et produit un signal d'horloge. Le système de recouvrement échantillonne le signal de données reçu en utilisant deux signaux d'horloge (573, 575) au moins et produit un premier et un second échantillon de signal correspondant. Ces échantillons sont utilisés pour produire des signaux de décision de symbole correspondants (581, 583). Ces signaux subissent un traitement qui cherche à détecter les configurations de symbole connues dans le signal de données reçu (513). Quant une suite binaire connue est détectée, les caractéristiques du système de recouvrement de signaux d'horloge sont modifiées; plus exactement, les largeurs de bande effectives des circuits de commande sont modifiées.
