Patent CA-2286943-C (CA)
Inventor: DE AMBROGIO ATTILIO
IPC: B41L21/02
Filed: 1999-10-20
Granted: 2007-04-24
Abstract: The invention relates to a device for picking sheets one at a time from a plurality of sheets in a ream in which the sheets are reciprocally aligned, for feeding of the sheets along a path. The device comprises a rotating means feeding roller; a tray for holding the ream, normally disposed at a distance from the main feeding roller and adapted to be moved so as to cyclically bring the ream into contact with the main feeding roller. At least one auxiliary roller is arranged parallel and adjacent to the main feeding roller, the former being adapted for counter rotation and contact with the sheets to permit their correct separation from the ream, without the feeding of double sheets occurring. The arrangement is free of the tendency to deform sheets of the ream to which prior feeding devices are subject.

Abstract: The present invention provides a gene search method comprising P-element insertion and being capable of efficiently identifying a novel gene regulating various biological functions of Drosophila and specifying a function corresponding to the novel gene. An unknown gene of Drosophila can be searched by the method comprising a step of inserting in the genome of Drosophila a gene search vector carrying two sets of an expression regulatory sequence comprising UAS sequence for GAL4 transcription factor GAL4 and a promoter sequence, as integrated in the P-element sequence in such a manner that their downstreams are in opposite directions, mating the vector-inserted Drosophila with a Drosophila expressing the GAL4 to create progeny individuals, and identifying a vector-inserted line with a phenotype different from those of wild-type Drosophila, and determining the nucleotide sequence of the gene for the mutant phenotype.

Patent CA-2302550-C (CA)
Title: An improved flow, axially-rotated, split venturi valve
Inventor: WALRATH DAVID E
IPC: E03B9/02
Filed: 1998-09-04
Granted: 2007-12-18
Abstract: The present invention provides an axially-rotated valve which permits increased flow rates and lower pressure drop (characterized by a lower loss coefficient) by using an axial eccentric split venturi (34) with two portions where at least one portion is rotatable with respect to the other portion. The axially-rotated valve typically may be designed to avoid flow separation and/or cavitation at full flow under a variety of conditions.  Similarly, the valve is designed, in some embodiments, to produce streamlined flow within the valve. An axially aligned outlet may also increase the flow efficiency. A typical cross section of the eccentric split venturi (34) may be non-axisymmetric such as a semicircular cross section which may assist in both throttling capabilities and in maximum flow capacity using the design of the present invention. Such a design can include applications for freeze resistant axially-rotated valves and may be fully-opened and fully-closed in one-half of a complete rotation. An internal wide radius elbow typically connected to a rotatable portion of the eccentric venturi may assist in directing flow with lower friction losses. A  valve actuator (48) may actuate in an axial manner yet be uniquely located outside of the axial flow path to further reduce friction losses. A seal may be used between the two portions that may include a peripheral and diametrical seal in the same plane. A seal separator may increase the useful life of the seal between the fixed and rotatable portions.

Abstract: L'invention porte sur un échangeur (10) modulaire consistant en une série de modules (61) tubulaires formés par extrusion d'un profilé d'aluminium. Chacun des tubes (62) extrudés présente une section transversale sensiblement rectangulaire, un alésage (66) traversant s'étendant longitudinalement entre deux faces (63) parallèles opposées, et des rainures (64) longitudinales parallèles en V, tous formés lors du processus d'extrusion, chacune des faces comportant une série d'ailettes (69) parallèles découpées dans la face (63) rainurée perpendiculairement aux rainures (64). Lesdites ailettes (69) ont une structure sensiblement en dents de scie accroissant les turbulences des flux d'air traversant l'échangeur (10). Les faces (68) d'extrémité non fendues des tubes (62) comportent des parties (71) rainurées remplies d'un matériau de brasage lors des phases de raccordement des tubes et de soudure du réservoir final. On obtient ainsi un échangeur entièrement en aluminium soudé de résistance sensiblement renforcée. Dans une variante, entièrement soudée, les faces d'extrémité allongées non fendues sont l'objet de percements croisés et sont obturées pour assurer une alimentation en liquide à la place des réservoirs d'extrémité.

Title: Belt drive for a belt conveyor
Inventor: EPP DWAYNE S
IPC: B65G41/00
Filed: 2000-06-19
Granted: 2004-04-06
Abstract: A belt conveyor has a continuous belt mounted within a tube for supporting a transportation run of the belt with the return run of the belt being guided along an underside of the tube. An undercarriage supports the tube and causes raising and lowering movement of at least the discharge end of the tube. A  drive roller is driven by a drive input with each mounted on the undercarriage at positions thereon which remains substantially stationary as the tube is raised so that the input remains in a fixed position as the tube is moved in said movement and so that the drive roller is fixed relative to the input drive member to receive drive therefrom without necessity for adjustment as the duct is moved. The drive roller is spaced from the return run of the belt on the underside of the tube and the belt includes a divergent portion having two runs extending from the return run to and from the drive roller to receive drive therefrom. Tension in the belt is compensated by an arrangement in which at least one idler roller is provided at the drive roller around which the belt passes so as to wrap the belt around the drive roller, the idler roller being adjustable in position relative to the drive roller to effect tensioning of the belt. The position of the idler roller is adjusted by a hydraulic cylinder attached to an accumulator of hydraulic fluid arranged to receive a fluid at a predetermined pressure such that the idler roller is pulled in a direction to apply tension to the belt at a predetermined force thus maintaining a predetermined tension in the belt while accommodating changes in belt length.

Title: Control system for bathers
Inventor: OTTO CINDY
IPC: H02H5/10
Filed: 1999-08-31
Granted: 2007-03-27
Abstract: A control system for bathers includes an electronic controller which controls operation of an electric heater assembly connected in a water flow path for heating water. The heater assembly includes a heater housing and electric heater element. A solid state water temperature sensor apparatus provides electrical temperature signals to the controller indicative of water temperature at separated first and second locations on or within the heater housing. The presence of water in the heater housing is detected electronically, by turning on the heater, and monitoring the temperature sensors for unusual temperature rises or other faults for a period of time thereafter.      A solid state water presence sensor apparatus can also be used to determine the presence of water within the heater housing, providing electrical water presence signals to the controller indicative of the presence or absence of a body of water within the heater housing. An independent circuit apparatus is connected to the water temperature sensor apparatus and to a power relay, automatically causing high voltage power to be disconnected from the heater assembly when the water temperature exceeds a predetermined temperature. The independent circuit apparatus requiring a manual reset once the water temperature has dropped below a predtermined level to allow the high voltage power to be reconnected to the heater assembly. The system includes ground continuity detection, ground current detection and ground fault detection circuits.
