Patent CA-2230185-C (CA)
Inventor: BEAUFORT RONALD E
IPC: E21B23/00
Filed: 1996-08-22
Granted: 2004-01-06
Abstract: A method and apparatus for propelling a tool having a body within a passage.  The tool includes a gripper including at least a gripper portion which can assume a first position that engages an inner surface of the passage and limits relative movement of the gripper portion relative to the inner surface.  The gripper portion can also assume a second position that permits substantially free relative movement between the gripper portion and the inner surface of the passage. The tool includes a propulsion assembly for selectively continuously moving the body of the tool with respect to the gripper portion while the gripper portion is in the first position. This allows the tool to move different types of equipment within the passage. For example, the tool advantageously may be used in drilling processes to provide continuous force to a drill bit. This enables the drilling of extended horizontal boreholes. Other preferred uses for the tool include well completion, logging, retrieval, pipeline service, and communication line activities.

Granted: 2005-01-04
Abstract: A locking device has a key operable locking head that is movable between a locked state and an unlocked state. The head has a housing with a rotatable retainer disposed therein. A lock core in the housing is axially oriented with respect to the housing opening. The lock core is mechanically coupled to the retainer and has a keyway to receive a key. Rotation of the key acts to rotate the lock core thereby causing rotation of the retainer to define the locked state and the unlocked state. A shackle includes a latch portion configured to engage for insertion into the locking head through the axial opening to define a mated state and configured to engage the locking head to prevent relative rotation therebetween. The latch portion includes a latch head configured for insertion through the aperture of the retainer when the locking head is in the unlocked state yet configured to prevent withdrawal from the aperture when the retainer is rotated to the locked state, whereby the latch portion is captured by the locking head to define a fastened state. The shackle member includes a linear portion and a stop portion disposed at a first end of the linear portion, the latch portion being disposed at a second opposite end of the linear portion

Filed: 1999-04-22
Granted: 2004-12-14
Abstract: A ginger plant containing curcumin, such as Ukon or turmeric, is enhanced for use as a food by fermenting it with a starch and red yeast. Each 100 weight of Ukon has mixed with it 1.0 to 20.0 weight of starch and 0.1 to 10.0 weight of red yeast. In addition, saccharides of 0.1 to 10.0 weight and minerals of 0.1 to 1.0 weight can be added to the mix. The fermentation process can be regulated by the addition of a mold of the Monascus genus. The water content is adjusted to 50 to 75 weight percent and the mixture is fermented for 5 to 1,000 hours at a temperature of 25 to 40°C. Prior to the addition of red yeast and mold and fermenting, the mixture can be sterilized for 1/2 to 1 1/2 hours at 110 to 130°C under a pressure of 1.05 to 1.15 atmospheres and, after fermenting, the mixture can be heat treated for 0.1 to 100 hours at 60 to 100°C.

Abstract: L'invention concerne un mécanisme de déblocage fonctionnant grâce à un manche de commande unique et destiné à être associé à une charnière de siège de voiture. Ce mécanisme comporte une plaque de montage qui se fixe sur un coussin de siège; une plaque cintrée montée de manière pivotante sur la plaque de montage, ce qui lui permet de pivoter de manière sélective autour d'un premier axe de rotation inférieur; et une plaque de commande de la rotation montée pivotante sur la plaque cintrée, destinée à pivoter de manière sélective autour d'un second axe de rotation supérieur et se fixant à un siège arrière. Le siège arrière du véhicule peut pivoter autour du premier axe de rotation inférieur, prendre une pluralité de positions angulaires, se plier vers l'avant par rotation autour du second axe de rotation supérieur et passer d'une position normale à une position basculée vers l'avant. Le mécanisme de déblocage comporte un dispositif de verrouillage primaire qui fixe la plaque cintrée pivotante par rapport à la plaque de montage, et un dispositif de verrouillage secondaire qui fixe la plaque de commande de la rotation pivotante par rapport à la plaque cintrée. Un manche que l'on peut saisir manuellement rend possibles des configurations bloquées et non bloquées du dispositif de verrouillage primaire. Un bras de liaison est interconnecté de manière fonctionnelle entre le dispositif de verrouillage secondaire et le coussin du siège en vue de permettre le passage du dispositif de verrouillage secondaire d'une configuration bloquée à une configuration non bloquée après mouvement relatif du bras de liaison et du dispositif de verrouillage secondaire au delà d'une position seuil. Cette opération permet de débloquer le siège arrière du véhicule pour qu'il se plie vers l'avant, sur le coussin du siège, par rotation autour du second axe de rotation supérieur, comme cela a été dit préalablement.

Abstract: An improved method and system of measuring the perceived speech quality in mobile telecommunications network are disclosed herein. In an embodiment of the invention, the method uses both radio link parameters and an objective measuring technique performed on received signals to estimate the speech quality perceived by the end-user. A radio link processing stage extracts temporal information from a set of available radio link parameters such as the BER, FER, RxLev, handover statistics, soft information, and speech energy. Concurrently, a speech processing stage is used to process a sequence of original signals and received signals, obtained from the output of a telecommunications system. The signal sequences are processed by an objective measuring technique such as Perceptual Speech Quality Measure (PSQM). The outputs from the radio link processing and speech processing stages are utilized to calculate an estimate for speech quality.

Abstract: An evaporator unit for use in the passenger compartment of a small bus that includes a low profile cabinet mounted in the ceiling of the passenger compartment against the back wall of the compartment. The cabinet contains a housing having a floor that slants downwardly from front to back and an evaporator coil is mounted in the front of the housing that is tilted rearwardly to reduce the height of the cabinet. A tangential blower wheel is mounted behind the coil and arranged to pass air from an inlet in the floor of the housing through the coil and out of the cabinet outlet. A shroud surrounds the blower wheel that cooperates with a baffle plate to efficiently conduct air through the unit. The top edge of the baffle forms the lower lip of the shroud exit region and the plate extends downward so that its lower edge is adjacent to the bottom of the coil to establish a converging air passage with the rear face of the coil to evenly distributes the air flow passing through the coil. A pan is mounted in the floor of the housing to collect condensate from the coil. The pan is exposed to a portion of the blower wheel so that positive pressure developed by the wheel helps to force collected condensate out of the back of the unit.
