Patent CA-2469784-A1 (CA)
Inventor: DORENDORF BRUCE
IPC: B05B7/06
Filed: 2002-12-13
Abstract: The invention includes a spraying device (10) for producing a precise degree of liquid droplet generation on a repeatable basis by combining a specified rate of regulated flow of liquid material with a regulated flow of high-pressure air. The spraying device (10) includes an electric or engine driven direct drive compressor (12). Coupled to the compressor (12) is an air storage tank (14) providing air pulsation reduction to the regulated air and serves as a reservoir for excess airflow generation. A Venturi nozzle (18) is connected to the compressor (12). A liquid supply tube (24) uses a fixed or variable restriction to regulate the liquid flow to the nozzle (18). The vacuum in the liquid supply line (24) draws thes liquid flow and mixes the liquid externally with the regulated air in exacting proportions forming specified liquid droplet sizes. The device (10) uses air and liquid regulation combined with a Venturi nozzle (18) and is able to generate extremely consistent liquid droplet sizes.

Patent CA-2473440-A1 (CA)
Title: Laser brightness
Inventor: BAGHAI SHAHIN
IPC: G01J5/08
Filed: 2004-07-12
Abstract: An infra-red measurement radiometer is disclosed having one or more laser emitters (10) to define a sighting area, characterised in that the brightness of the laser beams (24) emitted is controllable by the operator. Brightness of the laser beams can be increased or decreased to a useful extent by switching more or less lasers into or out of operations.  Brightness can be reduced by optical attenuation, such as the interposition of an optical element between the laser and the target, such as a diffraction lens or an iris device, or by use of an optical brightness fitter, as in photography. It is also possible to change the laser beam brightness by variation of the electrical power supply (Vs)to the laser emitter (10). This can be done with a resistor circuit (12), which may be fixed, or variable, and which may be located electrically between the laser emitter and power source, which is commonly a DC dry cell battery.  In accordance with the invention, the operator of an instrument is able to adjust the laser brightness, within safety limits, which allow enough brightness to be both safe and useful. When the target measurement or treatment area is located at a relatively long distance away from the instrument, or in obscure illumination conditions, greater laser brightness becomes valuable.

Inventor: YAMADA YOSHIKAZU
IPC: F02B75/04
Filed: 2004-08-03
Abstract: A variable compression ratio engine includes a connecting rod connected to a piston, a subsidiary arm connected to a crankshaft with one end pivotally connected to an end of the connecting rod, an eccentric shaft provided at an eccentric position of a rotary shaft rotatably supported at an engine body, and a control rod with one end connected to the subsidiary arm at a position deviated from the connected portion of the connecting rod and the other end pivotally connected to the eccentric shaft . In the variable compression ratio engine, a one-way clutch is interposed between the rotary shaft and the engine body, a restricted member is interlocked with and connected to an eccentric position of the rotary shaft to reciprocally operate corresponding to rotation of the rotary shaft, and a restricting device abuts to and engages with the restricted member immediately after the restricted member passes a reciprocation end, thereby selectively restricting a rotational operation of the rotary shaft in either of two rotation phases different from each other. Thus, the rotary shaft is rotated by utilizing the combustion and inertia of the engine, and occurrence of impact at the time of restricting the rotational operation of the rotary shaft can be suppressed.

Title: Fluid sensing in a drip tray
Inventor: ALBRITTON CHARLES WADE
IPC: B65B31/00
Filed: 2004-07-29
Abstract: A vacuum packaging appliance that detects the amount of liquid present while evacuating and sealing a container is disclosed. The appliance comprises a lid adapted to define a vacuum chamber when it is moved to a closed position relative to a trough in the base of the device. The trough in the lower portion of the device contains a heat-sealing element used to seal the contents of the bag once the vacuum packaging is complete. Disclosed are several embodiments relating to a liquid sensor molded into the walls of the trough. The liquid sensor comprises two electrodes that may be located on opposite sides of the trough or on the same side of the trough. When liquid is present in the trough, the capacitance and resistance between the electrodes changes, thereby sending a signal to a controller indicative of the amount of liquid within the trough while the container is being evacuated. The exact amount of liquid present is compared to a predetermined level of liquid. A vacuum pump controller may suspend operations if the amount of detected liquid exceeds a predetermined amount. The heat-sealing element is also controlled in accordance with the amount of liquid sensed in the trough. The amount of liquid sensed is also indicated to the operator.

Filed: 2004-10-25
Abstract: A system and methods are disclosed for providing independent virtual drives of a hierarchical file system across any number of computers within a Wide Area Network such as the Internet such that the number of directories and files within these file system drives is constrained only by the amount of storage system hardware. The system and methods allow many file system drives to occupy the same storage hardware but be totally independent of each other and uniquely identified and privately accessed by a set of encryption keys. The system and methods store the files in these systems as many separate blocks that are distinguished by a unique identity, encrypted locally on the computer equipment during a write operation and are transferred to different computers for storage across a large Peer-to-Peer network. The system and methods transfer these blocks back and decrypt them locally on the computer equipment and reassemble them to reproduce the original file. The system and methods use an algorithm based on a one-way function that is executed locally on the computer equipment performing the read or write operation to determine the identities for each block and decide on which Storage Peer each block will reside. This system and methods provide for a decentralized organization of the files of the file system drive. Access to a file system drive, its directories and files can only be achieved with knowledge of this set of encryption keys. Many independent file system drives, both public and private, coexist on the same distributed storage hardware based on different sets of encryption keys.

Ces brusques variations sont analysées pour élaborer une mesure du poids transmis au sol par chacun des essieux. La somme de ces poids fournit une mesure du poids total du véhicule. En cas de dépassement d'une limite prédéterminée, des alarmes et/ou actions sont déclenchées. Utilisation pour réaliser de manière simple, économique et systématique le contrôle du respect des poids maximum autorisés pour les véhicules franchissant un pont ou plus généralement empruntant un itinéraire déterminé.
