Title: Apparatus and method for winding paper
Inventor: OERTEMO BO LENNART HERBERT
IPC: B65H18/26
Filed: 1998-06-17
Granted: 2001-10-30
Abstract: An apparatus and method for winding tissue webs into a parent roll (25) is disclosed and includes a rotatable reel drum (19) having a flexible outer shell (23) for engaging a web (15) of tissue paper against a reel spool (26).  A deflection sensor (35) is mounted adjacent to the inner surface of the outer shell (23) for measuring the amount of deflection of the flexible outer shell (23) caused by the paper roll. The amount of deflection is related to the pressure at the nip point and, by moving the reel spool (26) and flexible reel drum (19) away from each other as the diameter of the paper roll increases, the pressure can be controlled at a desired level. Accordingly, a predetermined light nip pressure can be applied to the roll as the tissue web is wound thereon and large parent rolls (25) of high bulk tissue can be manufactured with desired properties when unwound.

Abstract: An instrument for analyzing and dispensing objects larger than about 70µm in diameter is based on a flow cytometer with a novel fluidic switch arrangement for diverting a portion of a sample stream in response to detector signals in a flow cell. The instrument is particularly adapted for dispensing multicellular test organisms like nematodes or large microspheres for use in screening large libraries of potential pharmaceutical agents. Hydrodynamic focussing is used to center and align the objects in the flow cell. The objects pass through a sensing zone where optical or other characteristics of the objects are detected. The detector signals are processed and used to operate a fluidic switch that is located downstream from the sensing zone. The fluid stream containing the detected objects emerges from the flow cell into air where a fluid stream controlled by the fluidic switch diverts portions of the stream containing no sample objects or sample objects not meeting predetermined characteristics. The undiverted sample stream deposits selected sample objects into a plurality of containers.

Granted: 2008-11-18
Abstract: Partially encapsulated stents are made using strips and bands of covering material. In one embodiment ringed stents are placed over an inner ePTFE tube (e.g., supported on a mandrel) and are covered by a seri es of longitudinal strips. A series of spaced apart ePTFE circumferential bands can then be placed over the top of the longitudinal strips and ringed stents; alternatively bands alone or strips alone may be employed. All of the components of the structure are then laminated t o the inner ePTFE tube to capture the stents. By selecting the size and position of the ePTFE bands, it is possible to leave critical parts of the stent unencapsulated to facilitate flexibility and expansion. The longitudinal strips can be woven about the stent of later laminated into position to provide an anti-compression function as well as overall structural stability. Although a single stent can be used, these approaches lend themselves to use of a plurality of individual ring stents spaced apart along the inner ePTFE tube.

Title: Thermosiphonic oil cooler for refrigeration chiller
Inventor: MOEYKENS SHANE A
IPC: F25B1/00
Filed: 2000-01-27
Granted: 2005-10-18
Abstract: Oil cooling is accomplished in a refrigeration chiller by flowing hot oil into heat exchange contact with liquid refrigerant which is sourced from the chiller's condenser (14) and returned thereto. The rejection of heat from the oil to the refrigerant in an oil-cooling heat exchanger (36) causes vaporization of the refrigerant and, in turn, creates a density difference in the refrigerant flowing from the condenser (14) and refrigerant in and downstream of the oil-cooling heat exchanger (36). This density difference is responsible for inducing and maintaining refrigerant flow through the heat exchanger (36) for oil cooling purposes.
