Patent CA-2221664-A1 (CA)
Inventor: ECKERT JUERGEN
IPC: E04F13/06
Filed: 1997-11-20
Abstract: In a sealing profile strip used to form a seal between one edge of a building component, such as a plaster board, and an adjacent building component, a mounting portion is adapted to cover a portion of an expansive surface of the first-mentioned building component when the sealing profile is installed along the edge of the first-mentioned building panel. A flange portion of the sealing profile is adapted to cover a portion of the edge of the first-mentioned building component when the sealing profile is installed therealong. For guiding a tool used to apply finishing material over the mounting portion, a rib portion of the sealing profile projects from the mounting portion and joins the mounting and flange portions. Two resilient sealing lips project from the flange portion, each for forming a seal between the edge of the first-mentioned building component and the adjacent building component when the sealing profile is installed therealong. For protecting the resilient sealing lip when finishing material is being applied, a tear-away strip projects from the rib portion. Being joined to the rib portion at a preferentially weakened juncture, the tear-away strip is torn away after finishing material has been applied.

Abstract: A composite Fresnel lens useful in an infrared passive detection system includes an array of Fresnel lens segments having a given vertical centerline and a curvature of a given radius. The Fresnel lens segments fall in first and second groups. Each Fresnel lens segment in the first group has a long detection range and a width less than one-third of the diameter of an original whole Fresnel lens from which the segment was taken. Also, each lens segment of the first group has a geometrical center located horizontally from the vertical centerline of the array along the curvature of the array through a circumferential distance less than one-fourth of the radius of curvature of the array. Each Fresnel lens segment in the second group has a short detection range less than the long detection range by a predetermined amount and a width less than one-third of the diameter of an original whole Fresnel lens from which the segment was taken. Also, each lens segments in the second group has a geometrical center located horizontally from the vertical centerline of the array along the curvature of the array through a circumferential distance less than one-half of the radius of curvature of the array. The Fresnel lens segments have respective optical centers which are aligned along the vertical centerline of the array. First and second Fresnel lens segments are aligned along the vertical centerline with the first Fresnel lens segment being the same in width as, being greater in length than, and disposed above, the second Fresnel lens segment. Third and fourth Fresnel lens segments are smaller in both length and width than the first Fresnel lens segment and disposed adjacent to opposite vertical sides of the first Fresnel lens segment offset from the vertical centerline.

Abstract: A lobster trap is formed with an entrance tunnel having inclined ramp surfaces designed to guide a lobster into an elevated position above the floor of the trap housing.  Each ramp surface terminates in a ledge or cliff, such that the lobster is caused to topple from the ledge downwardly onto the trap housing floor.  The elevated location of the ledge prevents the lobster from climbing up onto the ramp surface; the lobster is thus trapped in the housing.

Filed: 1996-09-11
Abstract: The present invention provides new methods, employing a nucleotide integrase, for cleaving double-stranded and single stranded DNA substrates at specific sites and for attaching nucleic acid molecules to the cleaved DNA substrates. One method uses a nucleotide integrase to cleave one strand of a double-stranded DNA and to concomitantly attach a nucleic acid molecule to the cleaved strand. Another method uses a nucleotide integrase to cleave both strands of a double-stranded DNA substrate and to attach a nucleic acid molecule to one strand of the DNA substrate. Another method uses a nucleotide integrase to cleave both strands of a double-stranded DNA substrate and to attach an RNA molecule to one strand of the substrate and for attaching a cDNA to the other strand of the substrate. Another method cleaves single stranded DNA with the concomitant insertion of a nucleic acid molecule at the cleavage point. The nucleotide integrase comprises an RNP particle which comprises a group II intron RNA bound to a group II intron encoded protein. The present invention also relates to purified and reconstituted RNP particles and reconstituted RNP that cleave DNA substrates.

Abstract: A tablet coating machine for applying a coating to a bed of tablets, the machine comprising a circular drum with frusto-conical ends which is rotated about its axis by suitable means. The periphery of the drum is perforated to allow air to flow through the bed of tablets disposed in the drum under the action of a suction shoe. In order to be able to optimise the efficiency of the tablet coating process for different quantities of tablets, the volumetric capacity of the drum is adjustable to achieve a desired tablet depth for the quantity of tablets being processed. More particularly an axially adjustable wall portion is provided within the drum to adjust the length of the tablet containing portion of the drum. The wall portion is made up of segments which are dimensioned to fit through an opening into the drum by which tablets are introduced into the drum. In one embodiment a threaded rod is connected between the wall portion and an end wall of the drum to facilitate adjustment of the wall portion within the drum. The area over which air is sucked from the drum by the suction shoe applied to the periphery thereof, is adjustable to tailor it to the length of the tablet containing portion of the drum.

Title: Packet network monitoring device
Inventor: MUKHERJEE SANDEEPAN
IPC: H04L12/26
Filed: 1997-01-28
Abstract: A network diagnostic device is disclosed that digitally samples the voltages on the cabling of the network (10), but does so at a much higher rate and with greater resolution than is required to minimally detect digital transmissions on the cabling. This sampling provides information on the analog characteristics of digital, noise, and interference signals on the network.  Thus, network problems can be precisely diagnosed. The device includes a fast digitizer (120) with a long memory (128a, 128b) and a system processor (140) that statistically analyzes the signal events captured by the digitizer (120).  The invention is also capable of performing time domain reflectometry (TDR) analysis of a functioning network. This is accomplished by placing (150) a TDR  signal on the network surrounded by a transmission that the network devices will interpret as a broadcast diagnostic packet. This will cause the network nodes to ignore the transmission. The digitizer, however, is able to detect the networks' response to the TDR signal. Methods for identifying unknown network sources and Manchester decoding are also disclosed.

Abstract: A bone connective prosthesis and method of forming same comprising the addition of a biocompatible plasticizer to a PMMA film and/or bone cement, which preferably copolymerizes with the PMMA film and/or bone cement. Preferably, this plasticizer comprises the FDA approved, biocompatible hydrophilic monomer known as 2-hydroxyethyl methacrylate (commonly referred to as "HEMA") and its associated water. HEMA has the ability to absorb water. An important feature of this invention is that this ability to absorb water results in a measurable and controllable plasticization. In one embodiment of the present invention, the plasticizer (HEMA and its associated water) copolymerizes with the PMMA film to form a PMMA/HEMA coating which is preferably used as a coating on a bone prosthesis. In a further embodiment, the plasticizer (HEMA and its associated water) copolymerizes with a PMMA base bone cement to form a PMMA/HEMA bone cement. In accordance with the present invention, one side of a PMMA/HEMA copolymer film is disposed on at least a portion of the surface of a prosthetic element. The other side of the copolymer film forms a bonding surface, wherein the bonding surface is adapted to be fixedly attached to a bone by a bone cement. Preferably, a PMMA/HEMA copolymer bone cement is used to fixedly adhere the prosthesis to the bone. The weight ratio of PMMA and HEMA in the copolymer bonding film or bone cement is not critical; however, the portion of HEMA should suitably be in the range between 2 weight % and 99 weight %.
