Patent CA-2135359-C (CA)
Title: Flow control valve assembly
Inventor: KLINE KEVIN B
IPC: G05D23/13
Filed: 1994-11-08
Granted: 2004-02-03
Abstract: A fluid condition controlled mixing valve assembly includes a valve body having a warm fluid inlet, a relatively chilled fluid inlet, a fluid mixing chamber, and a fluid outlet in communication with the mixing chamber. A thermally responsive control member, or thermostat, is disposed within the mixing chamber. A cylindrical liner is situated within the valve body with openings for chilled fluid flow and warm fluid flow. Concentrically located piston and valve disc are connected through an actuator to the thermostat so that the piston and disc move according to the thermostat response to the fluid temperature in the mixing chamber. The piston controls flow through the fluid openings. The liner and the shuttle define primary and secondary passageways. Fluid flows through the primary passageway when the flow control member is in a normal operating condition, i.e., with substantial fluid flow through both inlets. If flow through one of the inlets ceases, the shuttle moves to a failure condition, in which substantially all flow from the inlets is directed through a secondary passageway. This provides a fluid of a desired condition when there is substantial flow through both inlets and a fluid of a less desirable but acceptable condition when substantial flow through one of the inlets ceases.

Patent CA-2144564-C (CA)
Inventor: JANELLE LUC
IPC: A01C7/20
Filed: 1995-03-14
Granted: 2004-06-22
Abstract: A hydraulic downpressure system for use on no-tillage seeders allows for a constant downward force to be applied on seeding tools operating in highly variable soil surface conditions in order to keep a uniform seeding or planting depth. Raising and lowering of the seeding units can also be achieved with this hydraulic system. A double acting hydraulic cylinder is principally used having its rod end connected to one or two seeding units. A hydraulically operated two-way mode selection valve provides system shifting between both modes involved.        The first mode- is used when transporting the seeder on roads and to operate the seeding tools in the field. Control is then provided by a three-way directional valve mounted to an external hydraulic power supply, such as an agricultural tractor.      Raising and lowering of the seeding tools can be achieved when operating in this mode. A second mode is involved when the seeding tools are working into the ground to sow seeds. Pressure applied on both ports of the hydraulic cylinder comes from a nitrogen accumulator that acts as a pressure absorber which results in a net downward force. The cylinder can thus move independently while always maintaining the same force. A second three-way directional valve regulates the pressure in the accumulator and protects system from overload pressure. Downpressure adjustment is directly dependent from this control valve. A pressure compensator prevents a differential of pressure during system mode changes. The force from one cylinder can be applied on two seeding units using a double linkage system.

Abstract: An apparatus and method for retrieving densely stored data from various types of magnetic media. A medium is scanned to provide an input signal. The input signal is conditioned through differentiation, equalization and partial integration. Positive and negative signal peak detectors are connected to the conditioned signal, and a threshold signal is generating corresponding to an average or midpoint of the measured positive and negative signal peaks. An output signal is generated by comparing the conditioned signal and the threshold signal. The DC component of the input signal is accounted for by feeding back the output signal and adjusting the threshold signal based on the duty cycle of the output signal.

Title: Mail processing system with unique mailpiece authorization assigned in advance of mailpieces entering carrier service mail processing stream
Inventor: PINTSOV LEON A
IPC: G06Q20/40
Filed: 1995-10-03
Granted: 2003-06-03
Abstract: A mailing list is created including destination addresses for mailpieces to be submitted to a carrier service for delivery. A unique mailpiece identifier associated with mailpieces on the mailing list is generated by the carrier or other trusted third party. The unique mailpiece identifier is printed on the mailpiece with which it is associated. The mailpieces with the printed unique identifier are submitted to the carrier service. The carrier service obtains the printed unique identifier from the mailpiece. The obtained unique identifier from each said mailpiece is utilized to verify that data associated with the mailpiece has been processed by the carrier or trusted third party. When the unique number has been obtained from the mailpieces, the carrier service, if desired, may note this fact in the carrier records to prevent reuse of the unique identifier. The carrier service as part of issuing the unique identification may: charge the mailer's account of other fund depository for the carrier service charges associated with the mailpiece; and/or, assign a destination delivery code; and/or, provide address hygiene for the mailpiece; and/or change of address processing. When the unique identifier is obtained from the mailpiece, a delivery point destination code may be printed on the mailpiece, based on the corrected address. As an alternative, the destination delivery code may be provided to the mailer with the unique mailpiece identifier to be printed on themailpiece by the mailer. Various cryptographic techniques may be employed to authenticate the mailer and the carrier service and to protect the transmitted information between the parties. The payment for the carrier services can be implemented prior in time to the entry of the mailpieces to the carrier service mailstream. Unauthorized mailpieces may be out sorted early in the carrier service processing procedure.

The handle also includes an endcap which cuts into and seals the endcap against an outer grippable material upon tightening of a flanged nut onto the mounting. A lip extends from the handle and encompasses a portion of the mounting to facilitate increased torque transfer from the handle to the mounting and blade. The replaceable handle can also be formed of other grippable materials such as wood.

Abstract: Détecteur d'oxyde d'azote comportant au moins une paire d'électrodes, soit une première électrode et une deuxième électrode, placées de telle façon que les électrodes entrent en contact avec un électrolyte solide conducteur des ions oxyde, la première électrode au moins étant constituée d'un oxyde d'un élément du Groupe 7a ou 8, choisi en particulier parmi Mn, Fe, Co et Ni, ou une substance contenant cet oxyde, ou un oxyde composite (y compris un oxyde à faible teneur en oxygène) comprenant un élément du groupe 7a ou 8, représenté en particulier par la formule ABO3, AB2O4, A2BO4 ou ACBO4, ou une substance contenant cet oxyde composite. L'oxyde ou l'oxyde composite constituant le matériau de l'électrode est actif pour l'oxygène et NOx, mais présente une activité catalytique réduite pour CO2. De ce fait, le détecteur décrit peut être efficace sans être affecté par un changement de concentration de CO2, même à une température de 600  DEG C ou plus, et peut donc mesurer la concentration en NOx avec une grande exactitude, lorsqu'il est placé dans le flux de gaz d'échappement à haute température.
