Abstract: The temperature dependency of an EDFA is compensated in a wavelength of 1570 to 1600 nm to realize a wavelength division multiplexing transmission, First and second long period gratings different in grating period from each other are formed in an optical fiber. The peak wavelength of the waveform of the light transmission loss characteristic of the first long period grating is formed on the shorter wavelength side than a transmission band.      The peak wavelength of the waveform of the light transmission loss characteristic of the second long period grating is formed on the longer wavelength side than a transmission band. The wave forms of the above respective light transmission loss characteristics and the peak wavelengths of the wave forms are shifted depending on the temperature, and the light transmission loss value on the shorter wavelength side of the transmission band is increased as the temperature becomes higher, and the light transmission loss value on 'the longer wavelength side of the transmission band increases as the temperature becomes lower, to thereby compensate the temperature dependent gain characteristic of the optical amplifier in the gain compensation band on the shorter wavelength side and the longer wavelength side of the transmission band.

Patent CA-2354376-A1 (CA)
Title: Material treatment method and apparatus
Inventor: NILSON RON
IPC: B09C1/00
Filed: 2001-07-31
Abstract: An apparatus and method are provided for treating base materials, such as ore of a leach pad in a precious metal mining operation. A tilling head of the apparatus includes a cutter having a cutting face for engaging and loosening compacted base materials. The tilling head is extended into the base material down to a tilling depth so that the cutter moves loosened base material up and over the top of the tiller apparatus before depositing it in a pile opposite the cutting face. The loosened base material is deposited a distance from the tilling head that is sufficient to create a void between the tilling head and the pile that extends down to the tilling depth to prevent the loosened base material from being disturbed by the tilling head. The tilling head can be positioned so that the cutting face undercuts the base material to thereby assist the cutter in moving the loosened base material and increase the distance between the tilling head and the pile. An additive delivery system of the apparatus applies an additive, such as a leaching agent, remediation agent, or agglomerating agent, to the loosened base material as it is tilled and deposited by the tilling head. As it is deposited onto the pile, the loosened base material forms a slope having an incline substantially equal to the angle of repose so that the slope serves as a mixing area to improve coverage of the additive throughout the loosened base material.

IPC: A61B1/00
Filed: 2000-01-27
Abstract: A endoscopic multiple sample biopsy forceps is disclosed having a jaw assembly with a pair of jaws connected to a pair of arms extending from a jaw housing. Each jaw has two shanks oppositely displaced from the longitudinal axis of the device to define a space in the rear of the jaw for storing collected tissue samples. The tissue storage space defined by the jaw shanks opens rearwardly into a tissue storage area defined within the housing. Each shank has a broad outwardly facing planar surface aligned with an inwardly facing planar surface on one of the pair of arms. A  cam slot on each jaw shank is slidably engaged by a cam pin on one of the pair of arms.  A puller member coaxially positioned in the housing and axially movable relative to the housing supports a pair of pivots, each of which pivotally engages a bore on at least one jaw shank. The puller member is attached to a drive wire coaxially positioned in a tubular shaft. Axial movement of the drive wire actuates the puller member. In response to axial movement of the puller along the longitudinal axis of the outer tube, the cam pins riding in the cam guide slots change the position relative to the fixed jaw pivot axis of the jaw, thus actuating the jaws. None of the jaw assembly elements movable relative to the device, except the jaws, are externally exposed such that they could contact targeted tissue and negatively affect tissue sampling operations. An ejector is provided to push collected samples from the tissue sample storage area.
