Title: Internally sized cellulosic products and method for making same
Inventor: SPRINGS KENNETH E
IPC: D21H17/56
Filed: 1997-07-14
Abstract: The present invention pertains to an improved method of internally sizing a cellulosic article and an improved internally sized cellulosic article where a water-dispersible, water- and alkali-insoluble internal sizing agent from an interpolymer of an ethylenically unsaturated hydrocarbon monomer and an ethylenically unsaturated carboxylic acid comonomer is applied to fiber stock or pulp slurry some amount of time subsequent to the instance of application of a retention aid. The invention also includes a novel internal sizing composition where the interpolymer is rendered water-dispersible by reaction with an inorganic neutralizing cationic compound. The improved method is particularly well suited for paper making wherein substantially improved sizing performance is obtainable. Internal sizing agents based on inorganic neutralizing cationic compounds such as, for example, potassium hydroxide, provide the surprising advantage of hard water resistance.

Patent CA-2268648-A1 (CA)
Title: Storage devices for flat data storage media, in particular disc-shaped data storage media
Inventor: BRAND MIRKO
IPC: G11B33/04
Filed: 1999-04-13
Abstract: In order to reach deeper lying objects in a loose pile of objects it is usually necessary to start by removing objects lying side by side or on top of each other, which are in the way. This problem also affects the organized and compact storage of storage media, such as CDs and the like. The storage system enables simple and direct access to randomly arranged storage devices located deep inside the system. This is achieved with drawer cases that can be stacked side by side or on top of each other and that accept extendable drawers for the data storage media. The direction of insertion of the data storage medium into the drawer is at right angles to the direction along which the drawer slides into the drawer case.      Due to the fact that the storage of the individual flat data storage media is parallel to the axis for pushing in the drawers, the end of a storage cell extending in depth is of minimal area. This structure guarantees optimal utilization of the available space.

Title: Method and apparatus for coupon management and redemption
Inventor: FAJKOWSKI PETER W
IPC: G06Q30/02
Filed: 1997-10-27
Abstract: The present invention provides a system for the electronic management and redemption of coupons.      The system includes an integrated coupon card (1) comprising a memory means (22, 23), a scanner, and a communication port. The card is capable of scanning coupon bar codes and receiving data from a periphery device (27). The card will allow bar codes and redemption data to be transferred to a periphery device and will store what bar codes were redeemed. The system further includes one or more periphery devices (100), a communication port for communicating with coupon card and with a cash register. The periphery devices receive purchase data from a cash register and compare said data to coupon bar codes received from said card in order to determine which coupons are redeemable.      The system also includes a server computer (200).      The server will collect redeemed coupon information from the periphery devices and provide the periphery devices with redemption information. A clearing house will collect coupon redemption information from the system to create redemption reports.
Patent CA-2270305-A1 (CA)
Inventor: CIARAMELLA ERNESTO
IPC: H04B10/2581
Filed: 1999-04-27
Abstract: In a communication system with an optical fibre transmission line, a compensation of chromatic dispersion due to the fibre is performed through at least one compensation module based on chirped optical fibre gratings having a group delay characteristic ~(.omega.) which exhibits ripples around a nominally linear profile, as a function of the optical signal frequency. To minimise the effect of said ripples, the compensation is carried out in such a way that, for a given fibre length, the operating point is located in a limited slope region along the curve representative of system performance degradation owing to chromatic dispersion.

Title: Method for reducing foaming of lubricating oils
Inventor: VERNON PATRICK DESMOND FRASER
IPC: C10M155/02
Filed: 1998-01-07
Abstract: Foaming of a lube oil comprising a base stock derived from wax isomeration and an additive package is effectively reduced to within specification limits of 50 ml/ml over a temperature range of from at least 24 ~C to 93.5 ~C by adding to the oil an effective amount of an antifoamant exhibiting a spreading coefficient of at least about 2 mN/m. This has been found to be particularly effective in reducing foaming of lube oils containing a mixture of a wax isomerate oil and a petroleum oil fraction. Antifoamants typically used with conventional lube oils containing one or more petroleum fraction base stocks, but which do not exhibit a spreading coefficient of at least 2 mN/m with the wax isomerate containing oil, have been found not to be effective in reducing the foaming of the oil.

Each pair of contacts is connected to one twisted pair of e.g. a UTP cable. The arrangement reduces inter-pair cross-talk.

Abstract: The method for determining the phenotype of a haptoglobin in a biological fluid, characterized in that it comprises the steps of (a) contacting the biological fluid with a haptoglobin binding partner, in particular with Streptococcus pyogenes, which has at least two locations by which it can bind to haptoglobin so as to be able to agglutinate haptoglobins and/or to be agglutinated thereby to different degrees, depending on the haptoglobin phenotype; (b) measuring the degree of agglutination; and (c) determining, based on the degree of agglutination, the phenotype of the haptoglobin in the biological fluid. The kit comprises the haptoglobin binding partner and optionally a reference haptoglobin sample. This kit and method can be used for estimating a patient's prognosis following viral infection, for determining graft survival following liver transplantation, and for improving the interpretation of different laboratory parameters. Compared to existing assays, they enable a quick determination of the haptoglobin phenotype.

Patent CA-2285802-A1 (CA)
Inventor: SCHAFRANEK ALEX
IPC: G06F12/06
Filed: 1999-10-08
Abstract: A method and apparatus are disclosed for dynamically determining a bus address that uniquely identifies a hardware component on a common bus. In illustrative cell station implementation, each cell station includes a hardware controller that communicates on a common bus with a plurality of hardware components. The address space is logically divided into two ranges, namely, a first range of addresses referred to as the common access addresses, and a second range of addresses referred to as the assigned addresses. One address is reserved for the primary node that is responsible for assigning addresses, such as the hardware controller. Thus, each hardware component communicates with the hardware controller on one of the common access addresses to request a channel, and thereafter communicates on an assigned address, once assigned by the hardware controller. Collisions between multiple hardware components on the common access channels are minimized by assigning multiple channels.

IPC: B23P11/00
Filed: 1999-10-19
Abstract: An assembly technique and device for enclosing an open end of a movable socket (10) comprised of fully hardened materials with an expanding cover-plate (66) and for positioning the cover-plate at a predetermined distance from an exposed pressure plate (62) of the movable socket so as to provide a reliable indicator of socket wear. During assembly, various internal components of the movable socket, including the pressure plate, are installed within a housing (12) through a posterior opening (16) with the cover-plate is positioned over the components. A two-stage ram (100) having first and second contact surfaces (142, 167) is brought into engagement with the cover-plate. Pressure exerted by the two-stage ram is transferred to the cover-plate through the first surface, expanding the cover-plate into a generally planar configuration and enclosing the internal components within the socket housing.  A continued increase in pressure extends the second contact surface into engagement with the cover-plate, further deforming the cover-plate to a predetermined final position relative to an internal component for a consistent indication of wear on the socket components within the housing.
