Patent CA-2170794-C (CA)
Inventor: EAVENSON JIMMY NELSON SR
IPC: B60T7/04
Filed: 1996-03-01
Granted: 1999-11-02
Abstract: In a utility vehicle operable in either a runabout or continuous mode, a foot operated accelerator pedal switch activates a main relay to start the engine and to maintain the engine running as long as the pedal is depressed with a key switch in the run position.  When the pedal is released with the vehicle operating in the runabout mode, the main relay is deactivated and the engine is killed.  Depressing the pedal activates the main relay to start the engine and maintain the engine running.  The key switch is connected to latching relay structure and has a neutral run latch position.  The latching relay structure is operably connected to the key switch and to a parking brake switch.  The neutral run switch position and the latching structure permit continuous running of the engine as long as the parking brake is engaged.  To switch from the runabout mode to the continuous run mode, the operator moves the key switch to the special latch position and engages the parking brake to provide an alternate activation path to the main relay.  Releasing the parking brake or turning the key switch to the off position will shut off the engine.

Abstract: Nécessaire de nettoyage (101) utile dans le nettoyage des surfaces de salles blanches, d'unités de fabrication de semi-conducteurs, d'installations de fabrication de produits pharmaceutiques, etc. On a emballé ensemble une pile de chiffons d'entretien (14) extrêmement propres et un contenant (100) de fluide de nettoyage, dans un contenant (18) extérieur étanche aux liquides. On stocke ce nécessaire jusqu'au moment de son utilisation. Le fluide est libéré du contenant intérieur (100) dans les chiffons d'entretien. Dans un mode de réalisation, le fluide est libéré du contenant intérieur (100) dans les chiffons d'entretien (14), de préférence au moyen d'un dispositif de perçage (102) pouvant être actionné afin de percer l'une des parois du contenant intérieur (100) et ce par application d'une pression sur une zone limitée située sur l'extérieur du contenant extérieur (18). Le dispositif de perçage est éloigné des bords de l'emballage afin de minimiser les chances d'un perçage accidentel. Le liquide de nettoyage peut alors imbiber les chiffons d'entretien, lesquels (14) sont enlevés du contenant extérieur (18) en vue de leur utilisation. On peut sceller à nouveau le contenant extérieur, afin de protéger les chiffons d'entretien (14) après ouverture de l'emballage. Ce dispositif ainsi que son mode d'emploi minimisent la détérioration des chiffons d'entretien consécutive à un contact prolongé de ceux-ci avec le fluide de nettoyage, et ils minimisent également la perte d'efficacité des substances telles que des biocides, lesquelles peuvent s'altérer par suite dudit contact prolongé.

Abstract: An attenuator for signals in the frequency band of 50 to 800 MHz is subject to a range of AGC signal attenuating potentials. The attenuator includes a first attenuating PIN diode connected in series between an input and an output. The opposite ends of the first PIN diode are AC coupled via second and third impedance matching PIN diodes to an AC ground. The first PIN diode exhibits a frequency dependent slope over the wide signal frequency band and the range of AGC potentials. First and second inductors, in the form of metallic foil strips, are connected between the second and third PIN diodes and the AC ground. The foil strips are positioned in close proximity to each other and arranged such that signal currents flow therein in opposite directions to establish a negative mutual coupling coefficient for compensating for the frequency dependent slope of the first PIN diode.

Abstract: L'invention est une méthode utilisée dans un système de commutation pour les télécommunications sans fil pour déterminer, en rapport avec chaque station de base, si un appareil portatif doit recevoir un signal d'alerte audio ou un signal d'alerte par vibration en cas de réception d'un appel. Le système de commutation en cause utilise des instructions d'alerte pour les stations de base; ces instructions ont été introduites par l'administrateur du système. Par ailleurs, les utilisateurs individuels peuvent spécifier l'utilisation de signaux d'alerte par vibration dans les aires desservies par des signaux d'alerte audio selon les spécifications de l'administrateur du système. Les instructions spécifiant l'utilisation de signaux d'alerte audio ou d'alerte par vibration données par l'administrateur ou les utilisateurs individuels portent sur des périodes qui varient d'une station de base à l'autre. L'administrateur du système peut fixer directement les instructions d'alerte des stations de base individuelles. Il peut également fixer ces instructions dans différentes aires de l'immeuble et, à mesure que de nouvelles stations de base s'ajoutent au système, celles-ci héritent des attributs des aires dans lesquelles elles se trouvent.

Abstract: A method for installing a wireless network, which includes the steps of physically installing a plurality of nodes in respective different locations in a building, and using a wireless installation device to program a respective address into the nodes. The wireless installation device may also be used to program one or more default settings into the nodes, to verify operation of the nodes, and to dump information regarding the physical location and associated address of the nodes to a building computer. The wireless programming of the nodes is preferably accomplished using a software "handshaking" procedure which ensures that the address and default setting data is only loaded into the node currently being programmed, and not inadvertently into one or more other nearby nodes. In this connection, an iterative power reduction scheme can be utilized to prevent multiple nodes from being inadvertently assigned the same address.

Filed: 1998-06-08
Granted: 2005-03-29
Abstract: An apparatus for magnetically treating fluids removed from a hydrocarbon well is described. The apparatus includes a hydrocarbon section and a reactor section. The hydrocarbon section is designed to treat crude oil to inhibit the deposition of paraffins, asphaltines, and the like. The reactor section is designed to treat aqueous fluids to inhibit the deposition of scale, and the like. The magnets in the two sections are arranged in a linear, co-axial relationship. Radial focus magnets are provided in the reactor section to distort the magnetic field and provide radial exposure of the magnetic flux. The advantage is a simple, effective arrangement of magnets that requires minimal space and therefore minimizes interference with fluid flow.
