Title: Method of controlling a turret winder
Inventor: LOCKWOOD FREDERICK EDWARD
IPC: B65H23/195
Filed: 1996-05-22
Granted: 2002-12-03
Abstract: A web winding apparatus (90) and a method of operating the apparatus are disclosed. The apparatus can include a turret assembly (200), a core loading  apparatus (1000), and a core stripping apparatus (2000). The turret assembly  (200) supports rotatably driven mandrels (300) for engaging hollow cores (30 2) upon which a paper web (50) is wound. Each mandrel (300) is driven in a clos ed mandrel path (320), which can be non-circular. The core loading apparatus (1000) conveys cores (302) onto the mandrels (300) during movement of the mandrels (300) along the core loading segment (322) of the closed mandrel pa th (320), and the core stripping apparatus (2000) removes each web wound core (302, 51) from its respective mandrel (300) during movement of the mandrel (200) along the core stripping segment (326) of the closed mandrel path (320 ). The turret assembly (200) can be rotated continuously, and the sheet count p er wound log (51) can be changed as the turret assembly (200) is rotating. The apparatus (90) can also include a mandrel (300) having a deformable core engaging member (3100). The web (50) is transferred from a driven bedroll (5 9) to the turret assembly (200). The turret assembly (200) is individually driv en and mechanically decoupled from the bedroll (59). The core loading apparatus  (1000)and the core stripping apparatus (2000) are both indiviudally driven and are mechanically decoupled from the rotation of the bedroll (59) and of the turret assembly (200). A common position reference is provided which can  be a function of the angular position of the bedroll (59) or a function of i ts accumulated number of revolutions. The position of the turret assembly (200) , the core loading apparatus (100) and of the core stripping apparatus (2000) is controlled in relation to the common position reference.

Abstract: The   railway   freight   car  brake   control   utilizes sequential pressurization of the brake cylinder from a first auxiliary reservoir and a second auxiliary reservoir during emergency.    Embodiments  utilize  a  first  supply  reservoir larger in volume than a second supply reservoir.   The first supply reservoir is used during a service braking mode.  The larger first supply reservoir provides improved braking in a service  mode,  while  the  sequential utilization  of  both reservoirs provides an improved level of emergency braking available during a loaded freight car condition.

Abstract: Rapid reestablishment of permanent virtual circuits (PVCs 15 1-15 6) between frame relay switches 12 1-12 4 in a frame relay (10) is accomplished by periodically polling the switches by a configuration controller (18) via an out-of-band connection to obtain PVC information from the switches. Should a fault occur, the fault is isolated and mitigated. Thereafter, the configuration controller (18) downloads the stored PVC information to the switches in parallel via the out-of-band connection to enable the switches to re-establish the PVCs quickly, rather than wait to do so via an in-band connection.

Title: Naso-gastric tube retainer
Inventor: BIERMAN STEVEN F
IPC: A61M25/02
Filed: 1998-01-26
Granted: 2008-10-07
Abstract: An adhesive device retains a medical tube, and particularly a naso-gastric tube, in relation to a patient with improved flexibility, strength and adhesion. The device includes a nose pad portion for attaching to a patient's nose and a tube attachment section for attaching to the naso-gastric tube. A substantially inelastic spine extends across a narrow or otherwise vulnerable neck portion, which connects the nose pad to the tube attachment section. The spine strengthens the retaining device against tensile and shear forces while allowing flexibility. At the same time, deflection of the spine does not cause internal elastic stresses sufficient to counter adhesion of the retainer to either the patient or the medical tube.

Title: Short body endoprosthesis
Inventor: KUJAWSKI DENNIS
IPC: A61F2/06
Filed: 1998-09-04
Granted: 2008-02-19
Abstract: The invention comprises, inter-alia, endoprosthetic implants for treating vascular defects, including abdominal aortic aneurysms.  Implants according to the invention have a short main body that can be positioned within a patient's aorta at a position above the renal end of an aortic aneurysm. The short main body includes a proximal, or renal, face that redirects the flow of blood into the openings of channels that can carry blood past the aneurysm. In this way, the flow of blood through the aorta is diverted into the two passageways and through the main body of the implant. Fluid exiting the implant can be carried by leg extensions and delivered to a healthy part of the patient's aorta or the iliac arteries. Accordingly, the implant provides a system for allowing blood traveling through the aorta to be carried by a vascular graft that spans an aortic aneurysm, thereby relieving fluid pressure on the thin wall of aortic aneurysm, and reducing the risk of death caused by a ruptured aneurysm.
