Title: Improved barb and expandable transluminal graft prosthesis for repair of aneurysm
Inventor: CHUTER TIMOTHY A
IPC: A61B17/04
Filed: 1996-03-26
Granted: 2007-09-25
Abstract: An improved prosthesis assembly for placement at: an aneurysm in the bifurcated lumen of the aorta and the common iliac arteries extending therefrom. The prosthesis assembly includes a single lumen graft or a bifurcated lumen graft having a main body and ipsilateral and contralateral limbs extending therefrom. The main body and ipsilateral and contralateral limbs each have a spring assembly about their orifices for conforming that portion of the graft to the wall of the vessel lumen. The main body spring assembly has an improved barb with first and second attachment arms for securely anchoring the spring assembly to the vessel wall. The improved barb includes two forms of mechanical attachment such as, for example, a helical coil body positioned around a spring assembly arm and, secondly, a bonding material such as, for example, solder for fixedly attaching the coil and spring assembly arm. The attachment arms of the barb are positioned longitudinally along the spring assembly arm for engagement with the vessel wall without engaging each other when the spring assembly is in a collapsed condition. The ipsilateral and contralateral spring assemblies also include the improved barb with only a single attachment arm for anchoring the spring assembly to the vessel wall.

Title: Tobacco expansion method
Inventor: WAGNER JOHN R
IPC: A24B3/18
Filed: 1996-06-20
Granted: 1999-06-15
Abstract: A tobacco expansion method is provided whereby cured tobacco is first moistened with a humectant solution, as is conventional in the industry, to increase the resident liquids thereof. Next, the prepared tobacco in shredded form is placed in a sealed chamber and the chamber evacuated to vaporize a portion of the resident liquids. Next, ethyl alcohol vapor is allowed to enter the pressure chamber below 70 mm (Hg) absolute to prevent a water-ethyl alcohol azeotrope from forming. Thereafter, a hydrocarbon vapor, such as n-pentane vapor, is directed into the chamber and the pressure restored to atmospheric. The n-pentane vapor diffuses into the cellular structure of the tobacco with the assistance of the ethyl alcohol, whereafter the tobacco is heated and the n-pentane and ethyl alcohol acts as a propellant to expand the tobacco.

Title: Integrated proximity warning system and end of train communication system
Inventor: KULL ROBERT C
IPC: B61L23/34
Filed: 1996-09-09
Granted: 2000-01-04
Abstract: Proximity warning system (PWS) functions are integrated into the locomotive control unit (LCU) of an end of train (EOT) communication system. The PWS operation provides increased information to train crews relating to the location and movement of other trains in the area. The PWS functions are supported with the addition of a separate high speed modem which can access the LCU transmitter. A second radio receiver, the same frequency as the existing LCU transmitter, allows reception of transmissions from other PWS equipped locomotives. A location determination device, such as a GPS receiver, establishes current location and direction. The PWS operation is controlled by a microcontroller which, together with the existing LCU microcontroller, manages the control of the integrated system operation.

Title: Wrapping material supply arrangement for large round baler
Inventor: MEYER BERNARD
IPC: A01F15/07
Filed: 1996-09-20
Granted: 1999-11-30
Abstract: A large round baler has a wrapping material supply arrangement mounted to its discharge gate adjacent an upright run of belts used for forming a bale within the baling chamber of the baler. A pair of wrapping material feed rolls are arranged with one roll being located forwardly of and above the other. The wrapping material feed rolls are located below a chamber for holding a roll of wrapping material and disposed for having wrapping material engaged with the rolls in an S-shaped or serpentine path beginning at the rear periphery of the rear roll, then extending about a lower half of the rear roll and through a nip or gripping zone between the rolls and then about an upper half of the front roll, thus leaving the rolls at the forward side of the front roll. A guide chute extends downwardly and forwardly from the forward periphery of the front roll at a relatively steep angle, the guide chute having a lower terminal end located vertically above a guide surface of a guide pan extending beneath the discharge gate in close relationship to a fore-and-aft extending run of the bale-forming belts, whereby wrapping material exiting the guide chute will gravitate to the guide surface of the guide pan. The belts move the wrapping material along the guide pan to the baling chamber for wrapping a formed bale rotating therein. A knife is provided for cutting the wrapping material at a location adjacent a lower end of the guide chute, and a resilient stop or anvil is located in the path of a cutting edge of the knife to ensure that cutting will take place along the entire length of the cutting edge. A wrapping material sensor is located for sensing when wrapping material is present in a path extending between the guide chute and a nip formedbetween the guide pan and the bale-forming belts.

Title: Image processing method, image processor, and pseudo-experience device
Inventor: GODEN TAKESHI
IPC: A63F13/52
Filed: 1996-06-27
Granted: 2001-08-07
Abstract: A system according to this invention comprises an image display means 300, a central processing unit 102, memories 103 - 108, a program processing section 100 which executes a game program which moves a moving object in a virtual three-dimensional space in which three-dimensional objects are arranged, and an operation section 200 which accepts speed data about the moving objects in the virtual three-dimensional space and outputs the data to the program processing unit. The operation section 200 outputs moving-object speed data to a perspective conversion unit 110. The perspective conversion unit 110 varies the distance between a viewpoint and a projection screen according to the relative speed of the moving object. As the effective visual area on the projection screen decreases, the range of the virtual three-dimensional space displayed in the effective visual area increases. This makes the field view angle of the projection screen variable according to the speed of the moving object.

Abstract: A set of inflatable well packing elements (11, 13) are separated by a variable length of tubing and are set in a well to isolate a segment of the annulus by applying fluid under pressure through a tubing string to the well packing elements. The flow of the fluid under pressure to the inflatable packing elements is regulated by a flow control valve (10) which automatically cuts off the fluid flow at a predetermined tubing to annulus pressure differential and opens communication between the tubing string (96) and the isolated well zone. Fluid may thereafter be pumped into or swabbed from the isolated zone. Upon completing the zone servicing, pulling the tubing string up slightly will both equalize the pressure across the inflatable packing elements, and deflate the packing elements. Thereafter, the tubing string may be retrieved from the well or, if desired, moved to another location which can be serviced in the same manner.
