Patent CA-2311443-A1 (CA)
Inventor: KETTUNEN AUVO K
IPC: D21C/
Filed: 2000-06-13
Abstract: By the utilization of a jet ejector (such as a thermocompresser) in a cellulose chemical pulp mill, it is possible to effectively increase the utilization of steam. The volume of steam from a flash tank which flashes black liquor from a pulp digester may be increased (e.g. at least about 10%), while the volume and temperature of the liquor discharged from the flash tank are decreased and its concentration increased, by operatively connecting the jet ejector to the steam discharge from a flash tank. The jet ejector is supplied with higher pressure steam from another source which can result in a low pressure or partial vacuum condition in the flash tank. The flash tank may be a single flash tank or one of a series of flash tanks, and an ejector can be associated with at least another flash tank in the series. The hot spent cooking liquor from the digester can be cooled in a heat exchanger (for example in indirect heat exchange relationship with a fresh cooking liquor) prior to introduction in to the flash tank or series of flash tanks. Alternatively a jet ejector may be used to increase the pressure of a low pressure steam flow in a pulp mill to make it suitable for alternative uses.

Title: Compliant high temperature seals for dissimilar materials
Inventor: RYNDERS STEVEN WALTON
IPC: F16J15/12
Filed: 2000-06-30
Abstract: A high temperature, gas-tight seal is formed by utilizing one or more compliant metallic toroidal ring sealing elements, where the applied pressure serves to activate the seal, thus improving the quality of the seal. The compliant nature of the sealing element compensates for differences in thermal expansion between the materials to be sealed, and is particularly useful in sealing a metallic member and a ceramic tube art elevated temperatures. The performance of the seal may be improved by coating the sealing element with a soft or flowable coating such as silver or gold and/or by backing the sealing element with a bed of fine powder. The material of the sealing element is chosen such that the element responds to stress elastically, even at elevated temperatures, permitting the seal to operate through multiple thermal cycles.

Abstract: This is the description of a containment and conveyance system for materials that fall from, or drip from overhead sources. The primary component of this system is a module that may come in various shapes and sizes, and can be arranged in a variety of configurations to adapt to specific uses. The simplest form of this module may often be referred to as a tray. The shape of the ridge around the peripheral edges of the module and the features that can be incorporated therein make it possible to easily allow the passage of wheeled and walking traffic. Enhanced structural capability may also be easily incorporated when necessary. This additional structure provides an inherent coupling feature, which may be useful for multiple arrangements of the containment module.

Title: Resource allocation
Inventor: JOHANSSON PETER
IPC: H04L12/70
Filed: 1999-04-23
Abstract: A pool of resource units is configured using a structure having plural levels including first level and second level resource blocks. Each first level resource block corresponds to an individual resource unit, where an individual resource unit is the smallest resource that can be allocated from the resource pool. The first level resource blocks are provided in groups. Each second level resource block corresponds to one of the groups of the first level resource blocks. The second level resource blocks are also provided in groups forming a next higher level of the resource pool. If a request is made for a first level resource block, an available first level resource block is allocated. If a first level resource block is not available, then an available first level resource block is created by converting a second level resource block into a corresponding group of first level resource blocks. One of the converted first level resource blocks is then allocated to the request. Resource blocks are restored to the resource unit pool structure first to any incomplete first level resource block grouping. If that returned block completes the grouping, a new second level resource block is made available. The resource pool may be reconfigured as needed to ensure an efficient configuration.  First and second pools of resource units are configured using a structure having plural levels including first and second level resource units. A relationship is established between one of the two pools of resource units. A request is made for a resource that requires a resource unit from both of the first and second resource unit pools. A single allocation procedure is employed to allocate resource units from both pools. If one of the resource units is available in one pool, the relationship ensures that the required corresponding resource unit in another pool is also available.

Filed: 1999-07-26
Abstract: A method and apparatus for making bowl-shaped snack food products, e.g.  tortilla chips. The method features placing chip preforms in open bowl-shaped cavities and partially frying the chip preforms by filling them with hot oil from above. Additionally, the preforms are partially fried from below by immersing the lower portions of the preforms in a vat of hot oil and transporting them through the hot oil. After cooking the preforms to a desired moisture content, at which point the preforms retain their bowl shapes outside of or independent of the mold cavities, the preforms are removed from the mold cavities and subsequently cooked to completion in a secondary frying operation. The invention also features an apparatus to carry out the method.

IPC: C01B7/19
Filed: 2001-04-30
Abstract: The process removes from a diluted gas one or more fluorine compounds present at a first concentration in the diluted gas and concentrates the fluorine compounds. This is done by directly contacting the diluted gas with a cryogenic liquid having a temperature less than or equal to about -150 F, thereby producing a vapor lean in the fluorine compounds and liquid enriched with the fluorine compounds at a second concentration. The second concentration is greater than the first concentration.

Title: Locking mechanism for chair and pushbutton control therefor
Inventor: HOBB GORDON DENNIS
IPC: G05G5/06
Filed: 2001-04-26
Abstract: A first chair part may be fixed relative to a second chair part by way of a sliding member attached to the first part which slides in a body attached to the second chair part. The chair parts are fixed relative to each other when a pin associated with the body engages in one of several apertures in the sliding member to fix the chair parts. A bent leaf spring may have an end engaging a collar on the pin. The other end of the leaf spring may be pulled to urge the leaf spring to pivot about a fulcrum created by the bend. However, if there is a force trying to move the sliding member with respect to the body (as may result from a spring between the two chair parts), a consequent shear force on the pin may be sufficiently strong to resist the urging of the leaf spring. In such case, the leaf spring will simply bend when its other end is pulled until the force between the body member and slider is relieved. The other end of the leaf spring may be pulled with an actuator device having a track bearing member with a closed loop track. An actuator member is linked to the other end of the leaf spring and has a track follower received by the track. The actuator member may be pushed against the urging of a spring to move the track follower between first and second locating positions on the track. Movement of the track follower from the first to the second locating position and back again causes no net rotation of the actuator member relative to the track bearing member.
