Title: Bar code arrangement for identifying positions along an axis
Inventor: SAUVE ERIC
IPC: G06V30/224
Filed: 2001-12-19
Granted: 2012-10-09
Abstract: A bar code arrangement allows determining positions along an axis. The bar code arrangement includes a plurality of bar code symbols, each having start and stop end characters and encoded data therebetween. The symbols are positioned in a column along the axis and are so oriented that each bar of the symbols is parallel to the axis and that two consecutive bar code symbols have different orientations, one being rotated 180° relative to the other. Scanning the bar code symbol corresponding to a particular position among the plurality of bar code symbols in the column allows identification of the particular position along the axis. A symbol scan is considered successful when two different characters are found in a symbol scan. In the form of a ribbon, this bar code arrangement is suitable to correctly detect a liquid level on a bottle of liquid.

Abstract: A paint cartridge (31) is provided with a wash fluid passage (43) which is in communication with a paint chamber (36), along with a wash fluid valve (45) which is adapted to open and close the wash fluid passage (43). Provided on the side of a replenishing stool (52) are a replenishing valve (61) which supplies or discharges paint to or from the paint chamber (36), an extruding thinner feed/discharge valve (86) which supplies or discharges paint-extruding thinner to or from an extruding thinner chamber (37), and a wash fluid supply valve (101) which supplies a wash fluid to the paint chamber (36) through the wash fluid passage (43).  Accordingly, upon opening the replenishing valve (61), wash fluid supply valve (101) and wash fluid valve (45), a wash fluid from the wash fluid supply valve (101) is allowed to flow into the paint chamber (36) through the wash fluid passage (43) and discharged through a feed tube (34) to wash away deposited paint therefrom.

Abstract: La présente invention concerne une méthode et des dispositifs de démultiplexage en divisions temporelles d'un groupe de capteurs en réseau Bragg à fibre optique en série, groupe qui contient plus d'un réseau Bragg. Le dispositif comporte un système d'affichage pulsé qui permet une réduction du bruit du système et une augmentation de la résolution et de la flexibilité des capteurs. Dans une version de l'invention, les signaux optiques réfléchis par le groupe de capteurs en réseau Bragg sont portillonnés par un modulateur optique à commande électronique avant que toute mesure de longueur d'onde soit prise afin de déterminer les données des capteurs. Cette solution offre plusieurs avantages importants, car les données des capteurs sont codées dans la longueur d'onde du signal optique, et non dans son intensité. Par conséquent, les données des signaux des capteurs ne souffrent pas de distorsion par le portillonnage. Comme cette dernière fonction, ou la commutation du modulateur optique est effectuée sur le signal optique, la vitesse du traitement électronique ne doit être déterminée qu'au niveau de la vitesse de variation des données des capteurs, et le choix de méthodes pour la mesure des longueurs d'onde n'est pas influencé par le portillonnage. Le dispositif peut comprendre un ou plusieurs amplificateurs optiques qui permettent le démultiplexage électronique des signaux réfléchis.

Abstract: A choke valve control system includes a choke- operating lever for opening and closing a choke valve of a carburetor, a choke spring for biasing the valve in an opening direction, and a damper for controlling the opening motion of the valve to a lower speed, when the choke valve is opened from its fully closed position by a biasing force of the choke spring. The choke-operating lever, the choke spring and the damper are connected to the choke valve of the carburetor. In this choke valve control system, the damper includes a damper housing, a rotor, and a damper oil which is accommodated in a sealed manner in the damper housing and applies a viscosity resistance to the rotation of the rotor, which resistance increases as the viscosity increases with decreasing temperature. Thus, the time required for opening the choke valve can be controlled in accordance with the level of the environmental temperature of an engine, thereby providing the stabilization of the warming operation of the engine and a reduction in fuel consumption.

Title: Remotely actuated multiple pressure direct acting relief valve
Inventor: CONNER RICHARD T
IPC: F16K17/06

Granted: 2006-10-17
Abstract: A multiple pressure direct acting relief valve is disclosed. The multiple pressure relief valve comprises an actuating cylinder, a relief valve and an adjustment screw interconnecting the actuating cylinder and the relief valve. The relief valve includes a low pressure spring which biases a poppet valve arrangement permitting the poppet valve arrangement to be actuatable at a first pre-determined pressure. The actuating cylinder includes a piston that is biased by a high pressure spring causing an additional compressive force to be applied to the poppet valve arrangement through an actuating rod received through the adjustment screw. When pressure is applied to the piston within the actuating cylinder, an additional compressive force is applied by the high pressure spring and the actuator rod to the poppet valve arrangement causing the poppet valve arrangement to be actuatable at a second pre-determined pressure. Lock nuts are provided on the adjustment screw that interconnects the actuating cylinder and the relief valve. When the lock nuts are disengaged, the position of the adjustment screw can be moved relative to the actuating cylinder and the relief valve permitting the adjustment of both pre-determined actuating pressures for the poppet valve arrangement.
