Title: Snap-in end fitting for pipes
Inventor: PETERSEN HORST UDO
IPC: F16L37/088
Filed: 1997-09-24
Abstract: An oil-pipe for an auto-engine has a quick-connect coupling. The pipe has a cold-pressed end-shape, which includes a radial flange. A clip abuts the flange, and secures the coupling. The larger the area of the flange, the more secure the clip, and a recess formed into the wall of the pipe immediately behind the flange adds area to the flange without requiring that the flange have a large external diameter. The recess can be rolled in, or can be formed by cold-pressing.

IPC: C12Q1/68
Filed: 1996-05-06
Abstract: Disclosed is a method for detecting one or more mismatches in a test nucleic acid which preferentially hybridizes to a reference nucleic acid. The method involves a) providing the test nucleic acid in its single-stranded form; b) providing the reference nucleic acid immobilized on a solid support, the reference nucleic acid being in its single-stranded form and the solid support being compatible with a slot in an electrophoretic gel; c) contacting the single-stranded test nucleic acid with the single-stranded immobilized reference nucleic acid under conditions allowing duplex formation, whereby the duplex is immobilized on the solid support; d) contacting the immobilized duplex with a resolvase (for example, T4 endonuclease VII) capable of recognizing at least one single base pair mismatch in the duplex under conditions which permit the resolvase to cleave the duplex; e) inserting the solid support into the slot of the electrophoretic gel under conditions sufficient to release all or a cleaved portion of the immobilized duplex into the slot; and f) analyzing the released product by gel electrophoresis, the presence of a cleavage product being an indication of a mismatch in the test nucleic acid.

Patent CA-2234359-A1 (CA)
Title: An easily deployable, expendable or recoverable floating radar reflective device
Inventor: BARKER DENIS
IPC: B63B22/16
Filed: 1998-06-08
Abstract: This invention is an easily deployable, expendable or recoverable floating radar reflective device. The invention can be bout with sufficient reserve buoyancy to allow the fitting of a number of optional devices, such as a GPS transceiver or lighting. Thus, the device can be used for a variety of applications including: man-overboard marker, radar testing, temporarily marking submerged objects or navigation points, search and rescue, naval gunnery practice and/or weapons testing, or any other application that requires a floating reflective station. The device is constructed of aluminum, and consists of a tetrahedron shape with a floatation pod with an integrated radar reflector at each apex. Each floatation pod is fitted either with scuttling devices, to cause the device to sink if recovery is not a preferred option, or plugs if recovery is required. The use of dissimilar metal in the scuttling devices and the pins that hold the device together allows the device to rapidly corrode once it sinks, alleviating environmental concerns. The device is collapsible for ease of storage, and can be either assembled by hand, or deployed automatically, depending upon usage requirements. The tetrahedron shape allows the device to roll due to the motion of the waves or the method of deployment, and always present the same shape and reflective area as a target for radar, or as a support for optional devices mounted on the structure.

Title: Conveyor system with driven roller transfer assembly
Inventor: LAYNE JAMES L
IPC: B65G47/26
Filed: 1997-04-14
Abstract: A conveyor system having an improved conveyor transfer assembly (10) is provided for transferring articles from the end of a first conveyor to the start of a second, in-line conveyor. The conveying surface of the transfer assembly is formed by rollers (26) driven by a magnetic coupling system (40) which delivers power from an independent power source (44, 46). In addition, magnets (60, 62) are used for providing a positive attachment between the conveyor transfer assembly (10) and the conveyor supports (20) which span between the first and second conveyors. Thus, when an article jam occurs adjacent to the transfer assembly, the positive magnet attachment is overcome and, likewise, the magnetic coupling between the power source (44, 46) and the rollers (26) is also overcome thereby releasing the power connection. This allows the transfer assembly (10) to be bodily lifted and released to prevent damage to the articles. The transfer assembly (10) may also contain a tether (98) connected to the frame to restrain and suspend the transfer assembly following its release.
