Abstract: The multiple level converter comprises a voltage source (SE) and a current source (C). A series of controlled commutator cells are interconnected with a series of capacitors (C1, C2, ...Cn), with a separate capacitor for each of its cells. There is also a control device consisting of an evaluation circuit (VMO1, 2, ...n) determining the average voltage on the terminals of each of the capacitors.

Title: Detecteur de niveau d'eau pour evaporateur d'eau d'erable

IPC: G01F23/24
Filed: 1997-11-17
Abstract: Dans un évaporateur servant à évaporer de l'eau d'érable utilisant du bois ou de l'huile comme énergie de combustion, avec des pannes (casseroles) et des boîtes à flotte pour approvisionner et régulariser le niveau de l'eau d'érable dans les p annes, on sait qu'il y a beaucoup de problème avec ces flottes, et qu'elles ne sont pas tr ès fiables. Un manque d'eau dans les pannes entraîne des dommages très importants à la panne ainsi qu'une perte de production considérable. Dans la présente invention, un sy stème de sécurité permet d'avertir et d'éviter qu'un acériculteur brûle ses pannes. Ce système étant doté d'un système électronique ainsi qu'une électrode permettant de déclen cher une alarme et d'arrêter si nécessaire les brûleurs à l'huile pour empêcher tout dommage aux pannes de l'évaporateur. Cette électrode est également munie d'un ingénieux dispositif permettant de lire le niveau de l'eau et ce même en présence de broue et d'écume, ce dispositif protège également tout contact accidentel de l'électrode avec toute pièce métallique de la panne ou de la boîte à flotte. Ce dispositif protèg e également l'électrode de tout jet d'eau indésirable provenant de la valve de la flotte. Il permet également de ralentir toute grande fluctuation rapide (vague) pour éviter des alarmes inutiles. Ce système d'alarme permet également d'arrêter les brûleurs à l'huile en cas de manque d'eau et de les repartir manuellement de façon sécuritaire pour éviter qu'il y ait explosion dans la chambre de combustion.

Title: Selectively aspirating stylet
Inventor: KOHNEN JANE L
IPC: A61M25/00
Filed: 1996-04-15
Abstract: A selectively aspirating stylet assembly comprises a stylet having proximal and distal ends, the proximal end in fluid communication with a fluid supply and the distal end disposed at or near the end of a catheter, cannula or other generally tubular member that is to be inserted to a specified location within a patient's body, so as to create a fluid flow path from the fluid supply through the generally tubular member to the specified location. A valve assembly located within the fluid flow path is operable to close off a fluid column within the stylet assembly to facilitate placement of the tubular member within the body, and to control the flow of fluids within the assembly. Insertion of the tubular member into the body is accomplished by placing a portion of the stylet within the tubular member, closing the valve assembly to create a closed fluid column; inserting the style/tubular member assembly into the body; and then, during the withdrawal of the stylet, opening or closing the valve assembly as necessary to control the flow of fluid within the style/tubular member assembly to avoid substantial aspiration of body fluid and tissue.
Patent CA-2219727-A1 (CA)
Title: Twin-sheet thermoformed pallet sleeve
Inventor: GREENE CORY D
IPC: B65D19/00
Filed: 1997-11-19
Abstract: Two twin-sheet thermoformed thermoplastic sleeve halves engage within peripheral grooves in an underlying pallet and an overlying cover. Each sleeve half has a full wall which is connected by integrally thermoformed hinges to twopartial walls. The integral connection between the sleeve walls gives advantageous rigidity to the pallet sleeve assembly, while the hinging of the walls allows economical manufacture and low volume flat storage of the sleeve halves in a knocked-down configuration. The hinges preferably have non-specific hinge axes, thereby providing long hinge life, impact resistance, and ease of operation. Vertical substrate tubes are totally encapsulated into each sleeve half to carry loads from a supported loaded pallet sleeve assembly. To effectively transfer the loads from the cover to the sleeve, sinuous transfer ridges are molded on the sleeves above and below the vertical substrate tubes. The transfer ridges are positioneddirectly beneath the cover reinforcing substrate to maximize the assembly's loadsupporting capability. The upper projecting lip of the sleeve is positioned to tend to cause the sleeve to bow inward, where interaction with the pallet contents contributes to overall stiffness. The pinch areas between the inner and outer sheets of the sleeve are preferably oval.

Title: Measuring heating value using catalytic combustion
Inventor: BERG RONALD ARTHUR
IPC: G01N31/10
Filed: 1996-05-21
Abstract: The heating value of a sample gas is calculated by a microcontroller (12) from the heating value of a reference gas, and from flow ratios determined as the gas is consumed by catalytic combustion. In a preferred embodiment, chambers (5, 14) of fixed volume are charged to a predetermined pressure with a reference gas and a sample gas, respectively, and flowed to the catalyst at variable, changing flow rates as pressure decays. During the discharge cycle, a pressure transducer (13) senses the decaying pressure and this information is input to the microcontroller (12), which computes molar flow rates and which also senses the power level of combustion through a bridge circuit (24) in the catalytic apparatus (8, 10). Based on a ratio of molar flow rates and a ratio of corresponding power levels, a heating value of the sample gas is calculated by the microcontroller (12) and output to a visual display or other output device.
