Abstract: ABSTRACT OF THE DISCLOSURE         A resilient closure snap fit onto a container having an end wall provided with a plurality of transverse grooves.  A resin is deposited on the top surface of the end wall and into the grooves.  If the closure is removed from the container, the top layer of resin and a portion of the resin in the grooves will fracture, thus indicating to the consumer that tampering with the container has occurred.         In another embodiment, the closure comprises a rotatable portion and a fixed portion.  The rotatable and fixed portion have grooves which are filled with a resin.          When the rotatable portion is pivoted away from the fixed portion to open the container, a portion of the resin fractures, thus indicating tampering with the container.         In another embodiment, the tamper evident closure comprise a closure body having an end wall and a skirt depending from the end wall and a closure lid movably secured to the closure body.  The end wall and the closure lid define an upwardly open recess.  A cured brittle layer disposed in the upwardly open recess such that a portion of the layer contacts the end wall and another portion of the layer contacts the closure lid, whereby relative move-ment of the closure lid away from the end wall will cause a readily visible irreversible fracture of the layer and separation of at least one piece of the layer from the closure lid and the end wall.  An associated method is also provided.

Title: Network system for data transmission
Inventor: BOMAN JAN
IPC: H04L12/44
Filed: 1990-02-06
Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to a network system for data transmission between two data processing units, e.g. a peripheral unit (PE) and a Token Ring network with a cable concentrator.  Full duplex transmission is effected over each transmission channel between the two data processing units. For this purpose, the transmission channel comprises a two lead connection (KOAX) with an adapter (APE, AMAU) on either side.  One of the adapters is coupled to a peripheral unit and the other to the media access unit (MAU).  Each adapter has a transmitting file (TS, TS') for receiving data which is to be transmitted on the two lead connection to the other adapter, a receiving file (TM, TM') for transmitting data to its coupled unit after being sent over the two lead connection from the other unit, and a sorting coupling (TB, Rb, 2; TB', Rb', 4) which sorts out the data on the two lead connection which the adapter has not sent out thereon itself, and feeds this data to the receiving filed (TM, TM').

Title: Repellent-treated, barrier-coated non-woven web
Inventor: WEBER ROBERT E
IPC: A41D31/00
Filed: 1991-08-01
Abstract: Disclosed herein is a repellent-treated, barrier coated nonwoven web. Nonwoven webs with small fiber and pore sizes can often be surface coated with a barrier coating such as latex to form a nonwoven which will act as a barrier to liquids. Surface coating of nonwovens having larger pores and fibers is more difficult as the coating often sinks into the thickness of the nonwoven web. The material of the present invention is a larger fiber/pore nonwoven web which will permit surface coating to form a material which has a good hand and cloth-like feel while also acting as a barrier to liquids. Such a material has a wide variety of applications including, but not limited to, personal care products, surgical drapes and gowns and other applications requiring barrier properties.

Title: Method to use a reaction by-product as a calibrator for enzymatic assays
Inventor: GRUYS KENNETH J
IPC: C12Q1/52
Filed: 1991-02-27
Abstract: A method to use a reaction by-product as a calibrator in an automated enzymatic assay is described. In particular, the reaction by-product pyruvate is used as an instrument calibration standard to measure the activity of alanine aminotransferase. Use of this method eliminates errors due to inaccurate pipetting and corrects for small optical deviations from the wavelength of interest in the instrument. Left uncorrected, pipetting error and optical deviation negatively impact the accuracy of the enzyme activity calculation. In the fluorescence mode, calibration with a pyruvate standard also eliminates having to use unstable NADH standards. The pyruvate calibration standard of this invention is shown to be stable in standard stability testing. This method can be extended to a number of other automated enzymatic assays. Like alanine aminotransferase, the accuracy of the activity calculation for other enzymes should be increased by use of this procedure.

Inventor: BAZINET NORMAN L
IPC: A01K85/16
Filed: 1991-11-08
Abstract: ABSTRACT A fishing lure has a stream-lined elongated body generally simulating a fish.  The body has a head and a tail and the tail is thin and curved to one side when the lure is in an upright position.  Except for the curved tail, the lure is symmetrical about a vertical plane through a centre of said body.  There are two movable lateral fins located near the head, one lateral fin extending outward from each side of the body.  The lateral fins are pivotally mounted at a forward edge thereof so that a rear edge of each lateral fin can rotate upward or downward relative to the forward edge.  Upper and lower lugs limit the degree of rotation.  In addition, there are two stationary rear fins located between the lateral fins and the tail, there being one rear fin extending from either side of the body.  The lure has suitable hooks and two suspension points for attaching a fishing line.  The lure is particularly suitable for ice fishing and still fishing and moves through the water in a circular manner when the fishing line is moved vertically upward or downward.  The lateral fins impart a strong forward motion to the lure.  Previous lures designed for ice fishing do not move nearly as quickly through the water or do not cut as wide a circle.
