Inventor: HIROE NOBUTAKE
IPC: B41J31/04
Filed: 1993-11-10
Abstract: This invention relates to an ink ribbon base fabric used for an impact type printer such as a serial dot printer and a line printer, and a production method thereof. Specifically, the ink ribbon base fabric consists of polyamide multi-filaments, and this base fabric has as many creases as the number of those of the third class or more when measured in accordance with JIS L1096. In a production method of such an ink ribbon base fabric comprising scouring a base fabric consisting of polyamide multi-filaments, and drying and heatsetting the base fabric, the method of the invention is characterized in that scouring is jet scouring and heat-set is carried out under tension so that as many creases as the number of those of the third class or more are left.
Patent CA-2153710-A1 (CA)
Inventor: VILANDRE GILLES
IPC: E02B15/04
Filed: 1995-07-12
Abstract: An apparatus that takes advantage of the adherence of hydrocarbonates to specific material and its fluidity as influenced by the temperature. The performances of the apparatus are related to the interaction of two horizontal concentric cylinders one rotating around the other and containing both collecting and recovery means, working simultaneously. A three way oil collection is achieved by the cylinder's exterior surfaces, by large conical discs and by oil scoops located between the two cylinders. Said collecting means are integrated with a central heating system and with temperature controlled recovery devices such as oil deflectors with scrapers and oil recovery reservoir with screw, so that any type of oil can be recovered efficiently from or near the water surface even in cold weather.

Title: Bridge Between Two Buses of a Computer System that Latches Signals from the Bus for Use on the Bridge and Responds According to the Bus Protocols
Inventor: KATZ SAGI
IPC: G06F13/40
Filed: 1995-11-06
Abstract: A computer system having an ISA bus and a PCI bus is provided with a PCI to ISA bridge having certain imbedded functions performed by PCI slaves on the bridge. In order to implement the bridge in slow CMOS technology, the PCI control signals are latched on the bridge. Since the PCI slaves on the bridge cannot respond with control signals on the PCI bus fast enough to satisfy the PCI bus protocol due to this latching, a logic device is provided on the bridge. The logic device monitors the unlatched master-slave control signals carried on the PCI bus, and in appropriate situations, drives the control signals on the PCI bus (within the time specified by the PCI bus protocol) that the PCI slaves would normally drive but are unable to within the time necessary to meet the PCI bus protocol.
Patent CA-2163078-A1 (CA)
Title: Method of inspecting moving material
Inventor: LONG WILLIAM R
IPC: G01N21/94
Filed: 1995-11-16
Abstract: This disclosure is directed to a glass inspection system for inspecting a transparent web of glass of indeterminate length as it moves along a predetermined linear path of travel at a predetermined, regulated and/or controlled speed. The web of glass is illuminated such that any defect in or upon the glass web appears as a shadow moving upon a relatively white/bright background. A number of high resolution CCD cameras "look" downwardly through the transparent glass web and are focused upon the white background to detect moving defect shadows. Each camera creates a succession of image fields or frames through which a shadow of a defect will pass as the defect moves with the glass web through the scan area of each CCD camera. Each image field defines a nominal light area and each defect shadowis depicted as a defect area of light differing from the nominal light of each image field area. Initially, a first image area is scanned to detect the presence of a first light area/shadow at a first position which might be indicative of a defect shadow created by an "apparent" defect moving with the transparent glass web. Subsequently, a second image field is scanned at a second predetermined position to detect the presence of the first defect light area or shadow at the downstream second position commensurate with the speed of movement of the transparent glass body. If the first defect light area detected at the first position is present and is detected at the downstream second position, the latter confirms the existence of the defect, as opposed to the possibility of a spurious first scan, dirt rather than a defect on or in the glass, etc.

Title: Apparatus and method for determining the size of particles using light scattering
Inventor: BENEDETTO ELIZABETH E
IPC: G01N15/14
Filed: 1994-05-26
Abstract: An apparatus and method are disclosed which allow the size of a particle (20) suspended in a medium to be determined virtually independent of the materials' refractive index. The apparatus includes a means (12) for producing a beam of collimated light (22), a means (13) for exposing the particles (20) to the collimated light (22), thereby scattering the light, a detector (14, 31), and a means (17, 41, 43) for preventing any of the light which was scattered by the particles (20) from reaching the detector (14, 31). The method of the invention comprises passing the medium containing the particle (20) through a beam of collimated light (22), so that the light which contacts the particle (20) will be scattered; deterring the light which was scattered by the particles (20) from being detected; detecting the light which was not scattered by the particle, and determining the size of the particle (20) from the decrease in the light intensity incident on the detector (14, 31).

Title: Litter straining and reclaiming device
Inventor: POIL JAMES E
IPC: B07B7/01
Filed: 1996-04-04
Abstract: The invention is a litter straining and reclaiming device which provides a simple and quick and simple system for separating and disposing of feces and urine saturated clumps of litter while reclaiming the still clean litter for reuse.  This is done by utilizing a manually removeable sieve tray recessed within an open faced litter box which sifts and separates the clean litter from the soiled litter when it is raised. the sieve is then placed in a second entirely identical litter box after which the combined sieve tray and second litter box are inverted and placed over and upon the first litter box containing the reuseable litter.  The combined litter boxes and sieve tray and litter therein are then inverted to allow the reuseable litter to fall into the second litter box containing the sieve tray.  After this combination is inverted, the originally used litter box is removed and can be stored upright under the combined refilled litter box and sieve tray.  The identical litter boxes are equipped with a combination of guide cones and opposing recesses to provide a seal about the flanged perimeters of the litter boxes to prevent spillage when combined litter boxes are inverted.  The flanged perimeters also provide a handle surface at both ends of the boxes.  The invention may be constructed rectangularly or squarely.  The invention can be constructed of plastic or of a suitable sheet metal.  This invention allows for the conservation and recycling of reuseable litter while simplifying the removal of feces and urine saturated clumps of litter from the device and this invention provides a container for the purpose of defecation and urination by household pets, primarily cats.
