Patent CA-2061306-A1 (CA)
Title: Heat shrinkable protective sheets
Inventor: STEELE ROBERT E
IPC: B29C65/00
Filed: 1992-02-17
Abstract: A heat shrinkable wrap-around sleeve comprises a heat shrinkable sheet with a heat stable strip welded on one end.  The free end of the heat stable strip is overlapped on the outer side of the opposite end of the sheet and welded thereto by heating applied directly on the outer side.  This allows the material of the strip to differ in its properties from the material of the sheet, so that the nature of welded closure can be tailored to particular applications.  It also allows manufacture of sleeves having hold-down adhesives applied on them to be  conducted with greater ease  and economy.   The sleeve can be manufactured using continuous welding, for example by heated wedge welding.

Title: Echo canceller
Inventor: YATSUZUKA YOUTARO
IPC: H04B3/23
Filed: 1992-03-11
Abstract: In an echo canceller used in a four-wire digital telephone circuit, a main echo estimator (21) and a sub echo estimator (22) are coupled with a receive path for measuring a receive signal, and subtracters (25, 26) are inserted in a transmit path for cancelling an echo component in a transmit signal. Filter coefficients in said estimators (21, 22) are adaptively controlled by a convergence control processor (24). The main echo estimator has a small step gain for updating filter coefficients so that the response to an echo is slow, while the sub echo estimator (22) has a large step gain and quick response for an echo. An register accumulator (23) is provided so that the filter coefficients by the sub echo estimator (22) are selectively accumulated on the related filter coefficients in the main echo estimator (21) according to operation modes, ordinary mode, accumulating mode, and reset mode. In an ordinary mode, said two echo estimators (21, 22) operate independently from each other, updating the filter coefficients. In an accumulating mode, when an echo output of the second subtracter (26) is lower than that of the first subtracter(25), and the filter coefficients in the sub echo estimator (22) converge, the filter coefficients in the sub echo estimator (22) are accumulated on the related ones in the main echo estimator (21), respectively, and after reset of the coefficients in the sub echo estimator (22), the mode is then switched to the ordinary mode. When the filter coefficients in the sub echo estimator (22) diverge, or echo output of the second subtracter (26) is larger than that of the first subtracter (25), the sub echo estimator (22) is reset, and then, the mode is switched to the ordinary mode.

Title: Data processing system
Inventor: FUJIWARA YOSHIFUMI
IPC: G06F12/10
Filed: 1992-09-18
Abstract: ABSTRACT        A data processing system has the function of translating a logical address made up of a partial space number, a logical space number and an address within a page to a physical address made up of a physical page number and the address within a page and accesses a memory section under the coexistence of various different page sizes.  The data processing system has a table holding section for holding sets of copies of different address translation tables stored in the memory section on a partial space basis.  The sets of copies are each assigned to a particular page size.  The data processing system also has a load control section for loading one of the address translation tables in the table holding section in response to an address translation table load command.  The data processing system also has a directory supervising section for supervising partial spaces each corresponding to one of the address translation tables held in the table holding section.  Finally, the data processing system also has a first loading section for executing, by defining the partial spaces assigned to the same page size as a single supervisory unit in the directory supervising section, load control over the address translation tables independently.          The invention allows the dynamic translation of addresses having different page sizes thereby enhancing efficient use of memory and improving the operating system overhead.

Abstract: A METHOD AND SYSTEM FOR LOSSLESS AND ADAPTIVE          DATA COMPRESSION AND DECOMPRESSION               Abstract of the Disclosure The invention provides a method and system for compressing and decompressing data in real-time in which compressed data uses significantly less memory than the raw data.    The  system compresses  data  by  calculating the differences between adjacent data values,  identifying a plurality of frequently occurring differences, tracking the frequency of occurrence of the  identified differences, generating a first encoding for the identified differences, wherein the length of the encoding is based on the fre-quency of occurrence, generating a second encoding for the differences other than the identified differences, and for each calculated difference, encoding the calculated differ-ence using the first encoding when the calculated differ-ence is an identified difference and encoding the calcu-lated difference using the second encoding when the calcu-lated difference is not an identified difference to effect the compression of the data.

A bearing housing (26) encloses the-bearing (24) and includes an array of access ports (40) circumferentially spaced around the perimeter.  A split conveyor frame (28) defines semicircular mounting rings (42) for receiving the bearing housing (26) and securely mounting the drive sprocket assembly (12).  A lubricant channel (44) is provided in the surface of one mounting ring (42), and the surface of the other mounting ring (42) provides a lubricant seal.  The lubricant channel (44) aligns with the access ports (40) of the bearing housing (25), and includes stopper plugs (46) at each end to restrict the lubricant flow.  A transfer tube (52) having a lubricant fitting (54) on a first end transversely extends across the conveyor assembly.  A lubricant passage (64) in the conveyor frame (28) extends between the lubricant channel (44) and a feed orifice (60) of the transfer tube (52).  Lubricant applied at the fitting (54) is communicated through the transfer tube (52) and lubricant passage (54) to fill the lubricant channel (44).  From the lubricant channel (44), lubricant is forced through the access ports (40) of the bearing housing (26) to effectively lubricate the internal bearing (24).

Abstract: A method for treating raw milk to produce treated milk having a lower bacterial content than the raw milk. The milk is homogenized and within about 5 minutes from the homogenization, subjected to dynamic microfiltration, to yield a filtrate which has a lower bacterial content than the initial raw milk. When the flow rate of milk through the microfilter drops below a predetermined level, the dynamic microfilter is removed from milk filtration service, flushed with water, and returned to milk filtration service, the steps being repeated as necessary until the membrane cannot be rejuvenated to a minimum filtration capacity, at which time the membrane is subjected to chemical cleaning to essentially restore the original filtration capacity of the membrane.

Title: Portable newspaper dispensing pack
Inventor: FONSEKA DAVID M
IPC: A45F3/04
Filed: 1993-06-25
Abstract: ABSTRACT OF DISCLOSURE           The device is a backpack with a removable plastic container to contain 28 to 33 newspapers of any size folded with elastic bands. The box-like container has an open top, a 30 degree angled base and adjustable openings at one of its sides and at the base to allow the stacked newspapers to be easily pulled out from one side of the bottom. The water-resistant backpack, into which the container is inserted, has a similar sized opening at its base to allow the newspaper to be pulled out whilst it is carried on one's back. The whole device with its contents weighs about 7.5 kilograms and facilitates easy dispensing and distribution of the newspapers in any terrain and weather and in half the time it takes to distribute an equal number of newspapers with existing methods. Even more time can be saved if pre-folded newspapers are stored in additional containers where only a switch-over of containers into the pack is required. The opening at the base of the backpack comes with a zipped flap inside the pack which can be used to convert the pack to a multi-purpose backpack.
