Patent CA-2139628-A1 (CA)
Inventor: WIGREN KARL TORBJOERN
IPC: G10L25/06
Filed: 1994-05-11
Abstract: Un discriminateur (24) effectue une discrimination entre des signaux stationnaires et non stationnaires. L'énergie E(Ti) du signal d'entrée est calculée dans un certain nombre de fenêtres Ti. Ces valeurs d'énergie sont stockées dans une mémoire tampon (52) et une variable de test VT est calculée (54) à partir de ces valeurs stockées. Cette variable de test comprend le rapport entre la valeur d'énergie maximale et la valeur d'énergie minimale dans la mémoire tampon. Enfin, la variable de test est testée par rapport à une limite stationnaire  gamma . Si cette variable de test dépasse cette limite, le signal d'entrée est considéré comme non stationnaire. Cette discrimination est particulièrement utile pour effectuer une discrimination entre les bruits de fond stationnaires et non stationnaires dans les systèmes mobiles de radio communication.

Title: Optical filter arrangement
Inventor: ORZI DOMENICO
IPC: G02C7/10
Filed: 1995-04-10
Abstract: An optical filter arrangement comprises at least two optical filter elements including a transparent substrate and an optical coating typically comprising at least two overlying optical thin films. The coating defines a first patterned area and a second surround area bordering the first area. The first area has substantially the same optical transmittance characteristics as the second area and different optical reflectance characteristics over at least a portion of the visible spectrum. The distinction between the first area and the second area is visually perceptible when viewed from one side of the optical filter arrangement and is substantially visually imperceptible when viewed from the opposite side of the optical filter arrangement. As a result, a coloured pattern or logo is only visible when viewed from one side of the filter arrangement. The invention extends to a method of forming such an arrangement.

Title: Filter arrangement for single-acting telescopic hydraulic cylinders
Inventor: PETERSON WALTER
IPC: F15B21/041
Filed: 1995-05-05
Abstract: A filter arrangement for a single acting, telescopic, hydraulic cylinder, useful to raise and lower a dump truck bed, is configured for installation in one line of a two-line dump pump to filter only hydraulic fluid returning to sump. This is accomplished by a first one-way check valve which blocks fluid flow through a filter element toward the hydraulic cylinder but allows fluid flow from the hydraulic cylinder to sump and a second one-way check valve, disposed in parallel with the filter element, to block flow to the sump from the hydraulic cylinder while allowing flow from the sump to the hydraulic cylinder so that returning hydraulic fluid passes through the filter element.  Preferably the filter element is disposed in a spin-on fil-ter assembly which includes the one-way check valves integral therewith.

Inventor: PATRIKAINEN TAPIO
IPC: B01D53/56
Filed: 1995-08-11
Abstract: Process for removing nitrogen oxides from the flue gases of a soda recovery boiler of a pulp mill.        In the method, to the flue gases of the soda recovery boiler is at first fed an oxidizing agent, such as chlorine dioxide or ozone, which oxidizes nitrogen oxide to nitrogen dioxide. Subsequently, the flue gases are led into a flue gas scrubber, in which a reagent coming from the circulation of chemicals of the pulp mill is injected into the flue gases, which reagent brought into contact with the nitrogen dioxide reduces the nitrogen dioxide to nitrogen. The flue gas contain-ing nitrogen is led out of the scrubber and the oxidized reagent is led back to the circulation of chemicals of the pulp mill.

Title: Tying method and tying apparatus for articles
Inventor: SAITO TSUTOMU
IPC: B65B13/28
Filed: 1994-06-30
Abstract: A tying method and apparatus which is carried to easily automatically band bar-like articles such as reinforcements or pipes and various other articles by a linear tying material. The apparatus comprises tying material feed means (6), tying material bending means (8), encompassing and guiding means (9), tying material cutting means (7) and twisting means (11), wherein a starting point is formed in a way such that a part of a continuous linear tying material w delivered from the tying material feed means comes into engagement with the tying material bending means so that the tying material is bended into a U-shape. In that state, the tying material is delivered from one side whereby the tying material is guided around an article to be tied by the encompassing and guiding means (9) while being bended into a substantially U-shape. The tyingmaterial is cut into a predetermined length, and both ends of the tying material are twisted together by a hook (25) of the twisting means (11). Since the tying material is automatically bended to form two strands and the tying is done only once thereby, the strength of the tying material is enhanced and the rigid tying can be made with a materially strong tying force. Further, since the twisting advances from the hook side toward the article to be tied, the twisting can be advanced till a looseness in the tying portion of the article to be tied disappears, thus enabling the strong tying.

Title: Shroud seal for shrouded electrical connector
Inventor: ANTHONY JOHN C
IPC: H01R13/52
Filed: 1996-04-29
Abstract: A shroud seal having an annular ring portion and an annular lip portion. The annular ring portion is installed on the shroud of an electrical connector such that the annular lip portion is axially compressed on the shroud by a mating shrouded electrical connector. The annular ring portion has a frustoconical inner sealing surface which is sized to be twisted from its original molded frustoconical form to a cylindrical form when installed around the shroud of the electrical connector.      This twisting of the shroud seal produces a concentrated hoop stress in the seal at its points of contact with the shroud. The annular ring portion and the lip portion are compliant to allow for large axial tolerance variations between the mating electrical connectors, and provides for low insertion force between the mating electrical connector. In one embodiment, the electrical connector is in the form of a plug having a tubular portion or seal guard for encircling the shroud seal to protect the seal.      In other embodiment, the electrical connector is in the form of an inlet having a mounting flange to mount the electrical connector to a wiring enclosure.
