Patent CA-2152237-A1 (CA)
Title: Procedure for quantification of coefficients
Inventor: CROCITTI VALERIE
IPC: H04N7/50
Filed: 1995-06-20
Abstract: The disclosure concerns a procedure for quantification of coefficients in a variable data rate image compression system, in the form of blocks and macro-blocks, said system including means of transformation of blocks of pixels into blocks of coefficients, means of quantification of these coefficients, means of storage of coded information before transmission, and means of regulation of means of quantification as a function of the state of the means of storage. The procedure is such that each image being divided into groups of blocks, at least when a so-called current image must be coded in inter mode, a quantifier is determined at the start of the current image, said quantifier being corrected by a correction coefficient recalculated before the quantification of at least one of said groups, said coefficient being a function of the difference between, first, the number of bits produced for all the groups of blocks previously coded and, secondly, a prediction of this number of bits, said prediction being based on the distribution of the bits during the coding of at least one image preceding the current image. The invention is applicable notably in the field of image compression at low data transmission rates.

Patent CA-2158429-A1 (CA)
Title: Antibodies and assays for determining mutations in the apc gene
Inventor: HILL DAVID E
IPC: C12N5/20
Filed: 1994-03-21
Abstract: Antibodies and assays employing them are taught which are useful for detecting the bulk of mutations which occur in the APC gene in familial adenomatous polyposis. The antibodies are specific for epitopes in the amino terminal or carboxy terminal portion of the protein. A variety of immunoassay formats are described which are all based on the observation that the bulk of the APC mutations which occur in familial adebinatous polyposis and sporadic colorectal carcinomas result in truncated APC proteins. Generally, either the size of APC proteins is determined or the relative binding of amino terminal-binding antibodies to carboxy terminal-binding is determined.

Patent CA-2177218-A1 (CA)
Inventor: BIANCHI SANDRO
IPC: A63B71/14
Filed: 1996-05-23
Abstract: The invention provides a hockey glove in which the flexibility of the fingers is substantially increased without detracting from the protection provided by padding along the back of the glove. Stalls are provided for the fingers in which a portion of each stall is not attached to the padding along the back of the finger, but is isolated from the padding overlaying the stall and only resiliently attached thereto so that when the fingers are flexed the padding follows the flexing motion, but restricts it only minimally. In a preferred embodiment an elastic strap is provided to form a resilient web between the isolated portion of each finger and its associated padding. When the fingers are flexed, the isolated portions of the stalls allow the fingers a greater freedom of movement while the fingers remain protected by the overlying padding because the elastic strap pulls the sections of padding along with the stalls. The thumb stall may optionally be similarly constructed.

Patent CA-2186492-A1 (CA)
Title: Bioreactor
Inventor: ZHANG SHUYUAN
IPC: C12M1/08
Filed: 1995-04-20
Abstract: A stainless steel column housing is capped with an O-ring sealed cover to form a sealed autoclavable sterile chamber. A pair of stainless steel mesh circu-lar cylindrical concentric inner and outer columns are within the chamber. A bed of porous glass spherical beads are packed in the region between the inner and outer mesh columns. The pH and DO are monitored and controlled while culture medium is continuously supplied to and from the sterile chamber. The outer mesh column forms an outer bulk medium chamber with the housing and the inner mesh column forms an inner bulk medium chamber. A ring sparger bub-bles air and CO2 mixture into the outer bulk medium chamber, the bubbles creating pressure differentials in the bulk medium chambers. These differentials cause radially bulk medium flow through the packed bead bed without pressure gradients in the bed and axial bulk medium recirculation flow in and between the inner and outer bulk medium chambers at their axial ends. The bioreactor is suitable for retroviral vector and animal cell culture production.
Patent CA-2188642-A1 (CA)
Title: Method and apparatus for measuring the orientation of optical axes
Inventor: MASON PHILIP L
IPC: G01L1/24
Filed: 1996-10-23
Abstract: This invention provides an optical and computation system that does not utilize moving parts, which enables the angular orientation of the optical axes on the surface of a birefringent material to be determined and comparably, the orientation of the optical axes within light emerging from that surface. Further, since this invention considers the relative orientations of the preferred axis or axes of polarization within light, this method is also applicable for determining the angular orientation of the preferred axis of polarization of elliptically or linearly polarized light or the orientation of the polarizing axis of the material causing the preferred direction of polarization. For birefringent generated axes, this invention allows for the principal axis to be identified distinctly from the quadrature axis and without ambiguity. This is achieved by consideration of the relative intensities of the light emerging from the birefringent or polarizing material when observed through a plurality of linear or elliptical polarizers whose axes are set at known and distinct orientations to the reference direction of the measurement system, and with the ambiguities in the determination of the principal axis in the birefringent system removed by use of the phase of the interference patterns resulting when the light passing along the principal and quadrature axes within the birefringent material is combined by the linear or elliptical polarizers.

Title: Differential flange header package
Inventor: JOHNSON JOEL L
IPC: B65D33/25
Filed: 1996-10-25
Abstract: A zipper for a reclosable package includes a male interlocking profile and a female interlocking profile having male and female interlocking members, respectively. One, and only one, of the male and female interlocking profiles includes an extended flange separated and separable therefrom by perforations. In a reclosable package, polymeric sheet material is bonded to the male and female interlocking profiles and, specifically, to both sides of the extended flange. The extended flange, so reinforced with polymeric sheet material, can thereafter be used as a header from which the package may be hung for display in a retail store. Because of the perforations separating the extended flange from one of the two profiles, the header may be readily torn from the package to provide a consumer with access to its contents.

Abstract: The invention relates to a method for transferring mass between a flow of a first fluid, preferably a gas phase such as a combustion flue gas, and a flow of a second fluid, preferably a liquid phase, where the first fluid is contacted with the outer surface of porous (semi-permeable) membranes, e.g. polytetrafluoroethylene (PTFE, Teflon ) membranes, in the form of hollow fibres having gas-containing pores and contacting the second fluid with the inner surface of the membranes. Useful membranes are characterized in that they e.g. have a porosity (.epsilon.) of at least 0.50, a mass transfer coefficient of e.g. at least 3 cm/s, and a tortuosity factor of e.g. at the most 1.4/.epsilon. when the porosity .epsilon. is lower than 0.80 and at the most 1.3/.epsilon. when the porosity .epsilon. is 0.80 or higher. The membranes may also be arranged in hollow tubular members where the mass transfer coefficient of the membranes is at least one tenth of the mass transfer coefficient of the gas phase. The invention also relates to an apparatus for the above-mentioned mass transfer having a tubular conduit with an open inlet end, where a part of the wall of the conduit comprises a plurality of hollow tubular members defining array(s) with interstices between the members allowing flow of the gas phase. The invention further relates to a process for absorption or desorption where porous membranes, e.g. the abovecharacterized membranes, are utilized and where an exceptionally low membrane area per cubic meter of gas handled is required.
