Patent CA-2154775-A1 (CA)
Title: A method for reducing the content of organic solvent in cellulose-reactive hydrophobing agents
Inventor: LINDGREN ERIK
IPC: D21H17/17
Filed: 1994-02-07
Abstract: The invention relates to a method for reducing the content of organic solvent in cellulose-reactive hydrophobing agents and use of the products obtained. According to the method the solvent is transferred from the hydrophobing agent to an aqueous phase by dispersing the hydrophobing agent in water. The aqueous dispersion is thereafter contacted with a sorbent or a gas whereby the solvent is transferred from the aqueous phase to the sorbent or the gas. Suitably, the hydrophobing agent is an alkyl ketene dimer, for the preparation of which toluene is generally used. Suitably, the sorbent is a zeolite which can be removed from the dispersion before this is used in papermaking, in particular for hydrophobation of paper.  Alternatively, the zeolite can be maintained in the dispersion since the solvent is strongly sorbed on the zeolite surface, whereby only very small amounts of solvent can exist in free form.

Patent CA-2159301-A1 (CA)
Title: Multiport analyzing with time stamp synchronizing
Inventor: ZHANG JING
IPC: H04J3/06
Filed: 1995-09-27
Abstract: A plurality of digital transmission network analyzers are arranged to analyze and compare the appearance of a data packet on the plurality of ports of a network.  Each analyzer has its own internal clock for time stamping of data packets in addition to other internal timing purposes.  In order to synchronize the time stamping of the packet as it appears to each analyzer at a each different port, the clock outputs of the several analyzers are connected together; and a controlling CPU commands one of the analyzers to supply the master clock to the others.  That master analyzer then commands the other analyzers to disable or disconnect their own clocks, thereby all of the analyzers involved in a given test are under timing control of the clock of the master analyzer.  Packet headers and time stamps are transmitted between analyzers for comparison, analysis, and reporting to the controlling CPU.  This analyzer intercommunication is done over a separate bus that interconnects all of the analyzers and the controlling CPU.

Abstract: A progressive multifocal ophthalmic lens is provided comprising an aspherical surface having a mean sphere and a cylinder at every point.    The aspherical surface comprises a distance vision portion, with a control point for distance vision, a near vision portion with a control point for near vision, and an intermediate vision portion between the near vision portion and the distance vision portion.    A power addition value A is defined as a variation in mean sphere between the control point for distance vision and the control point for near vision portion.    A base B is defined as a value of mean sphere at the control point for distance vision.    A width of the near vision portion varies not only as a function of the power addition value A, but also as a function of the value B of the base.    The  invention  thereby  ensures  the  presence  of  a substantially constant object field for all values of the power addition and of the base.

Title: Anchored/resilient hardwood floor system
Inventor: NIESE MICHAEL W
IPC: E04F15/04
Filed: 1996-01-08
Abstract: An anchored/resilient floor system includes at least one upper flooring layer supported by parallel rows of attachment members which are supported above a base by a plurality of compressible pads, the attachment members being secured to the base at predetermined positions therealong by a fastener construction which permits downward deflection under loaded conditions but prevents vertical raising of the members beyond their initial static position. The attachment members are anchored in a manner which does not hold the pads in a precompressed state when the floor is unloaded. The fastener construction is preferably a plurality of single-piece anchor pins, wherein each anchor pin has a depth stop which limits downward extension into the bore during installation. This single-piece anchor pin construction is particularly suitable for reanchoring or retrofitting an already installed floor at a significantly lower cost than that of installing a new floor, and the one-piece anchor pin may be adapted for use with a portable floor by using internally threaded anchors embedded in the base.

Title: Method and device for a product intended to be introduced into the human body, and scanning device for a model of the product
Inventor: ANDERSSON MATTS
IPC: A61C9/00
Filed: 1995-10-03
Abstract: A dental bridge can be manufactured with the aid of a model (2) which includes preparations (8, 9, 10). The contours of each preparation can be read off by a reading unit. A computer unit traces the said readings. With the aid of a computer program, the computer processes the read-off information in cooperation with an operator so that a construction based on the tracing is obtained. The position of each preparation in the construction is determined by an apparatus which is functionally separate from the scanning unit. This apparatus generates information items which can be related to the positions of the preparations. These information items are run concurrently with the readings from the scanner in the computer, which in this way can indicate the correct mutual positions of the preparations in the construction.
