Patent CA-2261221-C (CA)
Title: Improved cylinder
Inventor: KING JEFFREY R
IPC: F15B15/14
Filed: 1999-02-17
Granted: 2004-11-02
Abstract: A cylinder includes a cylindrical casing, a cap mounted to the cylindrical casing, a retaining member, a mounting member and a piston rod assembly which is positioned in the interior of the cylindrical casing. The cylindrical casing includes a casing wall which extends along a longitudinal axis and defines an interior, an open end, and a closed end. The piston rod assembly includes a rod end and a piston, with the piston including at least one piston seal sealing against an inner surface of the casing wall, which divides the interior of the casing wall into first and second fluid reservoirs. The rod end of the piston rod assembly extends through the cap and moves between extended positions and retracted positions as a function of the pressures in the first and second reservoirs. The casing wall may have a first annular groove adjacent the open end, and a first port, which is in fluid communication with the first fluid reservoir for delivering fluid to the first fluid reservoir, is provided in either the closed end or the casing wall. The cap includes a second port, which is in fluid communication with the second reservoir for delivering fluid to the second reservoir, and may include a second annular groove which is aligned with the first annular groove of the casing wall when the cap is mounted to the open end of the casing wall, thus defining a cavity therebetween. The retaining member is positioned in the cavity and limits the longitudinal movement of the cap with respect to the cylindrical casing and, yet, permits rotational movement of the cap with respect to the cylindrical casing about the longitudinal axis of the casing, thereby, permitting adjustment of the second port about the longitudinal axis of the cylindrical casing. The mounting member is rotatably secured to the closed end of the cylinder and allows rotation of a mounting attachment relative the cylinder while preventing longitudinal movement therebetween.

Title: Cutting inserts
Inventor: SATRAN AMIR
IPC: B23C5/22
Filed: 1997-08-26
Granted: 2008-02-05
Abstract: A cutting insert (10) has an upper surface (12) bounded by a cutting edge (14), a base (16), and a peripheral flank surface (18). The shape of the peripheral flank surface (18) varies along the height of the cutting insert (10). Near the top of the peripheral flank surface, it conforms to round or polygonal geometry of the cutting edge (14) so as to provide support for the cutting edge. Lower down the cutting insert (10), the peripheral flank surface (18) is shaped to provide transverse bearing surfaces (38) which have considerably lower pressure angles, i.e., resistance to tuming moments, than would be provided by the inherent geometry of the cutting edge. Preferably, these transverse bearing surfaces (38) are formed by recessed features such as channels (40, 42), and most preferably, as chevron-type channels.

For each of the luminance and chrominance signals of a colour video signal first and second quality indicators are obtained from normalized values of the introduced edges (23) and the omitted edges (24), relative to the output edge signal (23) and the input edge signal (24) normalized by first and second normalization factors, respectively. By using smeared Sobel filtering, correlation of calculated MOS and observed MOS by human test persons reaches a value of above 0.9.

Abstract: A system and method to determine in-situ stress field based on bore hole acoustic monopole and cross dipole measurements (120). A radially polarized monopole shear wave (130) is generated in a borehole. It is then determined whether the shearwave has split into shear waves. The difference in velocities between the two split shear waves is used to determine the stress induced anisotropy (110) around and near the bore hole. The difference in velocities of cross dipole shear waves and the direction of the fast shear wave are measured and used to determine the magnitude of the maximum shear stress and the maximum stress orientation of the geologic formation. A method of determining the stress velocity coupling coefficients from laborator measurements and field measurement calibration is disclosed. The effect of bore hole pressure on the field measurement calibration of determing the stress velocity coupling coefficients is taken into account. Additionally disclosed is a method for defining a stress indicator that is related to stress caused (110) rock deformation. The stress indicator can be used to determine if rock failure is impending and is usefull in sand control and bore hole stability applications.

Abstract: A Comfort Noise Generation (CNG) system is provided for use in open systems where there is no predefined protocol for transmission of Silence Insertion Descriptor (SID) information from transmitter to receiver. The receiver enters an underrun condition in response to periods of silence, and in response generates comfort noise. According to the present invention, the computation of the level and spectral characteristics of the background of the speech signal is done within the receiver, thereby overcoming the lack of a protocol to transmit the SID information during silence periods. These characteristics are computed as a gain parameter and a set of Linear Prediction Coding (LPC) parameters which are applied to a filter which filters flat-spectrum noise in order to generate noise that sounds like the background noise of the speech signal.

Abstract: A method of filling a natural hollow elongated casing with meat emulsion involves placing a natural casing on an elongated meat emulsion stuffing tube having a meat emulsion discharge end, closing an extended end of the natural casing over the discharge end of the stuffing tube so that meat emulsion exiting the discharge end will push the natural casing longitudinally by pumping meat emulsion through the stuffing tube for expansive discharge into the natural casing at a sufficient volume and velocity to provide the primary energy within the natural casing to move the natural casing forwardly off of the discharge end of the stuffing tube. The casing is extended through a hollow chuck (100). A resilient brake element (160) in the chuck is extended around the casing to impede its longitudinal movement. A thrust collar (200) is slidably mounted on the stuffing tube and is intermittently manually pushed against the casing to limit the length thereof but is insufficient to create compression pressure thereon. An apparatus for filling a natural casing has a thrust collar on the stuffing horn (16) for pushing the natural casing longitudinally, and a casing hopper (46) that can be pivoted from a forward operating position to a rearward inoperative position.
