Title: Combination stopper-shield closure
Inventor: BURNS JAMES A
IPC: B65D51/00
Filed: 1994-06-22
Granted: 1999-08-31
Abstract: A combination stopper and shield closure for sealing the open end of an evacuated body fluid collection tube. The stopper is headless and includes a well in its top surface with an undercut at its base. The shield includes a plurality of flexible fingers extending from its top surface, each finger including a cleat at its proximal end for engaging with the undercut in the stopper. The interaction between the cleats and the undercut serve to securely hold the stopper within the shield and eliminate compression forces being applied to the stopper by the shield. In addition, the base of the well is convex to direct any residue body fluid away from the center of the well towards the undercut and minimize residue build-up, and the bottom portion of the stopper is concave to reduce the thickness of the stopper's diaphragm and reduce penetration force.

Abstract: An air-fuel supply system for an internal combustion engine in which fuel, such as natural gas, is stored in a fuel tank as a cryogenic liquid, and in which supply air is compressed. The charge air is intercooled to increase its density and, therefore, engine performance. Heat from the intercooling process is utilized to vaporize the liquid natural gas fuel. Heat exchange from the charge air to the liquid natural gas is accomplished with a phase changing heat transfer fluid. The heat transfer fluid boils at the intercooler and condenses at the fuel vaporizer to give precise temperature control at the intercooler surfaces without frost build-up.

Title: Wrap-around carrier with end restraints
Inventor: HARRIS RANDALL LEE
IPC: B65D71/22

Granted: 2005-05-03
Abstract: The invention relates to a wrap-around carrier (34) with gusset panels (28) connected to the bottom panel (42) that automatically fold into their upright position when the bottom panel flaps are set up for locking engagement. The resulting upright portion s of the gusset panels contact the bottom portions of adjacent articles in the carrier to prevent the articles from falling out through the ends of the carrier. The fold lines (32) connecting these gusset panels (28) to the side panels (18) are angled back to lengthen these fold lines while cutouts (60) in the gusset panels shorten the length of the other fold lines (62, 66 ) of the gusset panels. This increases the pulling power of the gusset panels while decreasi ng the bias force which must be overcome in order for the gusset panels to be folded int o their upright position.

Abstract: A method and device for transcoding a digital signal first oversamples the input signal, converts the sampling rate to an oversampled output signal, filters the signal to reduce unwanted bands and decimates the oversampled output signal to produce a transcoded signal having the target sampling rate. This allows the conversion to be implemented in the composite domain, requiring a single sampling rate converter, and significantly reduces the complexity of the filter required to filter the output signal .

Abstract: This invention comprises the use of buoyancy forces to counter, in whole or in part, the gravity forces to which structures, such as buildings and bridges, are subjected during earthquakes.   It also comprises the retrofitting of existing structures, such as buildings and bridges, in zones of high seismicity, by introducing the forces of buoyancy to counter the gravity forces to which these structures are subjected.   Present practice is to accept the seismic forces at ground level and to design structures to resist the inertial forces to which they are subjected during seismic activity.   The concept of the present invention is to deal with the problem at the source; i.e., at ground level, thus eliminating, in whole or in part, the necessity for dealing with the problem within the structures.
