Patent CA-2167734-A1 (CA)
Title: Planning and toy assemblies, and the like, employing movable elements of permanent magnetic material
Inventor: BARLETT ERNEST R
IPC: G09F9/00
Filed: 1996-01-22
Abstract: Planning and toy assemblies of the invention comprise element receiving and storage members and a plurality of elements adherable by permanent magnet attraction to their receiving surfaces, the assembly also usually comprising a folder in which they are stored and carried. Each member comprises a thin sheet of magnetizable metal with a surface sheet mounted thereover. The receiving member surface carries a planning grid or picture, while the storage members have depictions on their exposed surfaces of the elements that are placed thereon. Each element is a piece punched from permanently magnetized sheet material of sufficient magnetic field strength to adhere to the metal sheets, even through a thin non-magnetic layer, and also carries a depiction of what it represents. Each element depiction has a respective visual orientation, while the sheet material has a respective magnetic orientation, and preferably while one plurality of the elements have their visual and magnetic orientations in a first angular relation, another plurality have their orientations in a different angular relation, so that elements of the two pluralities can overly one another without interaction of the magnetic fields that might otherwise cause unwanted relative movement between the overlying elements. A further plurality may have their orientations in an angular relation different from that of the other two pluralities for the same purpose. The two or three pluralities of elements may be formed by stamping from a single sheet of the material, and thereafter are mounted on the storage members with the same visual orientation.

IPC: F04C18/344
Filed: 1996-03-27
Abstract: A rotor vane and a method for fabricating the rotor vane are provided in which the vane is formed of a thermoplastic matrix material having chopped fibers uniformly dispersed throughout the thermoplastic material, with the fibers aligned to extend in directions which are approximately parallel to a radial dimension in which the vane extends.  A billet formed of the thermoplastic matrix material with the chopped fibers randomly oriented and uniformly dispersed within the thermoplastic matrix material is placed in vane forming dies.  The dies have an interior surface which is in the shape of the vane.  The billet is placed within the dies with the longitudinal length of the billet extending perpendicular to the radial dimension of the vane being formed and completely across the axial dimension of the vane being formed.   The billet is heated to a softening temperature and compressed within the dies to deform the billet into the shape of the interior surface of the dies, causing the thermoplastic matrix  material to  flow  in  flow  directions  which  are approximately parallel to radial dimension of the vane being formed.  Flowing of the thermoplastic matrix material in the flow directions aligns a substantial portion of the fibers with the flow directions, approximately parallel to the radial dimension of the vane.  Then the thermoplastic matrix material is cooled to temperature below the softening temperature and the vane is removed from the dies.

Patent CA-2177649-A1 (CA)
Title: Zero byte substitution method and apparatus for telecommunications equipment
Inventor: WISNIEWSKI JAMES J
IPC: H04L7/00
Filed: 1996-05-29
Abstract: An interface circuit is provided for implementing zero-byte substitution (ZBS) in a channel unit or line card which couples a digital subscriber line, such as a basic or primary rate Integrated Services Digital Network (ISDN) line,  to  a  T1  network  or  other  digital  transmission facility.  On the transmit side, the occurrence of an all-zero data byte in a B channel of the ISDN interface causes a corresponding  zero byte  indicator  (ZBI)  flag to be produced in the D+ channel, and also causes the all-zero byte to be replaced by the preceding non-zero data byte rather than by a prescribed or predetermined data byte.  On the receive side, the occurrence of a repeated data byte in a B channel is detected and causes the current data byte to be replaced by an all-zero byte to restore the original data.  The ZBI flag is then used as an error check bit to verify that  the reinsertion of  the  all-zero byte was correct.
Patent CA-2177697-A1 (CA)
Inventor: SANKEY JOHN PHILLIP
IPC: A61L2/16
Filed: 1994-12-12
Abstract: The incorporation of many percarboxylic acids, which otherwise could be incorporated in household formulations as disinfectants and/or bleaching agents, especially at hand-hot temperatures, is precluded or hindered by their adverse physico-chemical properties, such as a propensity to decompose too quickly during storage or explode on impact or when subjected to pressure. The invention provides a stable and effective selection of organic percarboxylic acids which satisfy the general formula (1): X-Ar - CO - NY - R(Z) - CO - OOH  in which X represents hydrogen or a compatible substituent, R represents -(CH2)n- in which n = 2 or 3, and Y and Z each represent independently a substituent selected from hydrogen or an alkyl or aryl group or an aryl group substituted by a compatible substituent or aralkyl group provided that at least one of Y and Z is not hydrogen if n = 3. The invention also provides bleaching, washing and disinfecting compositions containing such peracids and processes using them for such purposes.

Title: Method and system for managing aircraft threat data
Inventor: DEIS DAVID L
IPC: G01S13/88
Filed: 1995-01-17
Abstract: A method for calculating intervisibility data in advance of its use for permitting a real time update of threat information. Threat intervisibility data corresponding to an area comprised of adjacent regions is calculated and stored. A region of concern is centered in the adjacent regions. As the location of an aircraft changes, threats move from an adjacent region to the region of concern. However, since the intervisibility data was calculated when the threat first appeared in the adjacent region, it is now available for other functions without further processing. Such other functions include providing it to a threat avoidance algorithms or for display within the aircraft.

Abstract: A method and receiver for demodulating a DS/CDMA signal increases a receiver's (60) sensitivity and as a result, the system capacity of a DS/CDMA cellular communications systems.  A Reduced State Sequence Estimator (RSSE) (68) finds a path (210) with the highest energy.  An efficient method and apparatus for determining the path energies (212) selects a new path (210) to differ from a previous path (210) by a single reduced state (200).  A difference (306) between an I and Q magnitude of the new and omitted reduced state (200) is computed (304).  This difference is added to the previous path's total I (308) and Q magnitude, to compute the new path's I and Q magnitude.  These I and Q magnitudes are used to compute a path energy (322) and the highest path's energy (326) is used to select the best path for decoding (70).

Title: Composite papermaking fabric with paired weft binder yarns
Inventor: CHAPLIN DEREK G
IPC: D21F1/00
Filed: 1996-12-12
Abstract: A composite forming fabric in which the woven paper and machine side layers are interconnected by pairs of intrinsic Weft binder yarns which interweave with the paper side layer to occupy an unbroken weft path. Each member interweaves sequentially with the warps of the paper side layer and with at least one warp of the machine side layer. Each part of the unbroken weft path is separated from adjacent parts by at least one paper side layer warp yarns. The unbroken weft path is the same, or different, to the weft path of the immediately adjacent paper side layer weft yarns. This arrangement overcomes the paper side layer surface imperfections, which cause an unacceptable level of marking, hitherto associated with the use of intrinsic weft binder yarns in composite fabrics.
