Patent CA-2504503-A1 (CA)
Title: Variable orifice bypass plunger
Inventor: VICTOR BRUCE M
IPC: F04B47/12
Filed: 2005-04-20
Abstract: An improved plunger mechanism apparatus has a manually adjustable bypass valve to increase well flow production levels in high liquid wells. The plunger's descent rate can be fine tuned in the field by adjusting the orifice opening so that liquid can optimally flow through the plunger core during descent. Efficiency of well flow is increased by the addition of a variable bypass orifice, which can be preset in numerous positions to vary the amount of liquid bypass allowed depending on the well loading parameters. The plunger mechanism of the present invention allows numerous bypass set positions, which can be tuned at a well site and later changed as a function of future well loading parametric changes.

Abstract: A lawn and garden tool, such as a string trimmer, includes a lower housing, an upper housing having one or more axial channels interconnected with one or more circumferential channels disposed on an interior surface thereof and a shaft connected between the upper housing and the lower housing. A boss is located on an exterior surface of the shaft and is disposed within the channels such that the boss is capable of traveling back and forth between the interconnected axial and circumferential channels. Movement of the boss within one of the axial channels telescopes the shaft while movement of the boss within one of the circumferential channels rotates the shaft and, thereby, rotates the lower housing with respect to the upper housing. The shaft may be moved from a locked position upon actuation of a push-button mechanism located on the upper housing of the string trimmer.

Title: Automatic segmentation of texts comprising chunks without separators
Inventor: BADINO LEONARDO
IPC: G06F40/00
Filed: 2003-05-28
Abstract: Syntagms of a text including individual elements written without separators are segmented into chunks being comprised of strings including at least one individual element such as an ideogram of the Mandarin Chinese language. A  lexicon (LEX) is defined including a set of strings, each string being comprised of at least one of the individual elements. The syntagm being segmented is orderly searched on an element-by-element basis (INDX) by searching within the lexicon strings corresponding to any of said chunks. In the case of a positive search result, the corresponding chunk located is stored with an associated cost. A check is made as to whether the chunk located was already present in the lexicon. In the case the chunk located was already present, the cost assbociated therewith is reduced. A plurality of candidate segmentation sequences are thus generated, each corresponding to a respective segmentation pattern having associated a corresponding accrued cost. The candidate sequence having the lowest associated cost is selected as the final result of segmentation.

Title: Chemically-doped composite insulator for early detection of potential failures due to exposure of the fiberglass rod
Inventor: HUDAK STEPHEN J
IPC: H01B17/50
Filed: 2004-08-06
Abstract: A composite insulator containing means for providing early warning of impending failure due to stress corrosion cracking, flashunder, or destruction of the rod by discharge activity conditions is described. A composite insulator comprising a fiberglass rod surrounded by a polymer housing and fitted with metal end fittings on either end of the rod is doped with a dye-based chemical dopant. The dopant is located around the vicinity of the outer surface of the fiberglass rod. The dopant is formulated to possess migration and diffusion characteristics correlating to those of water, and to be inert in dry conditions and compatible with the insulator components. The dopant is placed within the insulator such that upon the penetration of moisture through the housing to the rod through a permeation pathway in the outer surface of the insulator, the dopant will become activated and will leach out of the same permeation pathway. The activated dopant then creates a deposit or stain on the outer surface of the insulator housing. The dopant comprises a dye that is sensitive to radiation at one or more specific wavelengths or is visually identifiable. Deposits of activated dopant on the outer surface of the insulator can be detected upon imaging of the outer surface of the insulator by appropriate imaging instruments or the naked eye.
