Patent CA-2386173-C (CA)
Inventor: SCHAFER MARK E
IPC: G01N29/04
Filed: 2000-09-21
Granted: 2008-11-18
Abstract: A system and method of detecting anomalies and/or grain variations in a wooden member. At least one ultrasonic transmitter (401) applies an ultrasound waveform into a surface of a wooden member (100) so as to generate a multiplicity of ul-trasonic waves including, e.g., longitudinal and shear waves. These ultrasonic waves are measured after propagation through the wooden member by at least one ultrasonic receiver (402) disposed on the same surface of the wooden member. At least one ultrasonic receiver (501) may also be placed opposite the ultrasonic transmitter (401) so as to detect radial transmission of the longitudinal ultrasonic wave at a point across the wooden member. The received ultrasonic waves are processed to determine anomalies and/or grain variations in the wooden member at positions of the wooden member between the ultrasonic transmitter and the ultrasonic re-ceiver(s). The ultrasonic transmitters and receivers the ultrasound may be placed in rollers to facilitate high-speed, in-line processing of wooden members.

Title: Methods for providing access to wireless resources in a trunked radio communication system
Inventor: BIGGS ROBERT A
IPC: H04L12/56
Filed: 2002-05-16
Granted: 2007-05-01
Abstract: Methods are disclosed for providing requested access, network-initiated access and autonomous access to communication resources (101-105) by wireless unit(s) (112, 114), and for controlling the different types of access using access control identifier(s) assigned to the devices. Requested access requires a unit to send a call request (302) to a resource controller (106). The request (302) includes an identification of the unit and an identifier associated with the unit. Network- initiated access comprises a resource controller or other fixed network equipment sending a page request (502) to the unit which responds with a page response message (504) including the identification of the unit and an identifier. The resource controller (106) determines, based on the identifier. whether a communication resource is available to support the request. Autonomous access comprises the unit (112, 114) receiving an advertisement message (402) identifying a communication resource and one or more identifiers associated with the communication resource. The unit determines its eligibility for autonomous access based an the advertisement message.

Abstract: A height adjustable table, preferably with a circular tabletop which includes a vertically telescoping column to support the tabletop and with the column telescoping between extended and retracted positions. A base supports lower end of the column vertically upright. A locking mechanism is provided within the telescoping column adapted to lock the column against telescoping when the tabletop is rotated in one direction relative the base and to unlock the column when rotated in the other direction. When the table is unlocked, a user may adjust the height of the table either by manually lifting alone or assisted by a lifting mechanism to bias the tabletop upwardly and at least partially bear the weight of the tabletop. A stop mechanism is preferably provided to ensure the table is not extended so far as to disengage the tabletop structure. The base of the table is adapted to be engaged by a user's feet to prevent rotation relative to the tabletop when locking or unlocking.

Abstract: A reel (20) comprises a drum assembly (22) enclosed within a shell comprising upper and lower shell portions (24, 26). The drum assembly (22) is secured to the lower shell portion (26). The drum assembly (22) comprises a motor-driven rotating drum (36) secured between two discs (38, 40), and a frame subassembly (23). The drum (36) is adapted to receive linear material (150) spooled thereon. An outer surface of one of the discs has a spiral groove (88), with a first end (90) near the center of the disc and a second end (92) near an outer edge.  The second end (92) is tapered to lesser depth. The frame subassembly (23) includes a track assembly (54) facing the disc with the spiral groove (88) and a translating plate (70) adapted to translate horizontally within the track assembly. As the drum and discs rotate, horizontal pins (76, 78) of the plate (70) alternatingly engage the spiral groove (88), causing the translating plate to translate linearly within the track assembly. The translating plate is connected to and causes the upper shell portion to reciprocatingly rotate about a vertical axis with respect to the lower shell portion and drum assembly. A guide aperture (128) is provided in the upper shell portion, through which linear material (150) is drawn onto the rotating drum (36). Advantageously, the aperture translates through an arc in front of the drum (36), so that the linear material (150) is distributed across the drum surface as it is wound.

Abstract: A single-part hollow shear coupling is provided for connecting a downhole pump with the terminal member of a sucker rod string. The coupling is threadably connected to the sucker rod and the pump during normal operations, but can relatively easily be parted, if the pump becomes stuck, by pulling up on the still free sucker rod string. One end of the coupling has a pin incorporating an externally threaded head and the other end has an internally threaded cavity. A cylindrical, hollow body joining both ends is weakened by the groove, providing a stress concentration point, where the coupling will part, when exposed to predetermined desired load. The weakened part of the shear coupling is protected with a special coating, preventing corrosion and abrasion.
