Subassembly Cartridge For Sealing And Adjusting Bearing Assemblies
View pageUS Patent:
40493288, Sep 20, 1977
Filed:
May 25, 1976
Appl. No.:
5/689938
Inventors:
Ralph C. Ouska - Hinsdale IL
Francois X. Bertaud - Aurora IL
Francois X. Bertaud - Aurora IL
Assignee:
Stephens-Adamson, Inc. - Aurora IL
International Classification:
F16C 3372
US Classification:
3081871
Abstract:
A combined bearing sealing and bearing adjusting subassembly for use with two members which rotate relative to each other upon a tapered roller bearing assembly, such as a belt conveyor idler roll which rotates relative to a stationary shaft upon a pair of axially spaced tapered roller bearing assemblies, and the combination of such a bearing sealing and bearing adjusting subassembly with a conveyor idler roll assembly. A separate cartridge-like subassembly is mounted between the two relatively rotatable members and contiguous each respective tapered roller bearing assembly. Each cartridge-like subassembly includes a combined contact seal and a labyrinth seal which cooperate to prevent ingress of foreign matter into the corresponding bearing assembly or the egress of lubricant from the bearing assembly. Each cartridge-like subassembly also includes a plastically and elastically deformable collapsible spacer member which absorbs clearances resulting from manufacturing tolerances of components of the idler roll assembly and also by controlled release of the elastic deformation of the spacer member provides a predetermined axial preload or, alternatively, end play adjustment of the corresponding tapered roller bearing assembly, as desired. The collapsible spacer is so characterized that it provides the same axial preload or end play, as desired, without individual selective adjustment, for the bearings of any one of a number of idler roll assemblies in which the components of the respective idler roll assemblies have dimensional variations within a given range of manufacturing tolerances.
Sensor Delivery Device
View pageUS Patent:
51123096, May 12, 1992
Filed:
Jul 25, 1990
Appl. No.:
7/558035
Inventors:
Francois X. Bertaud - Libertyville IL
Richard W. Grabenkort - Barrington IL
Beverly A. Magrane - Redmond WA
Gerald G. Vurek - Mountain View CA
Richard W. Grabenkort - Barrington IL

Assignee:
Abbott Laboratories - Abbott Park IL
International Classification:
H61M 2500
US Classification:
604171
Abstract:
A device for storing and delivering a sensor through a catheter. A sensor delivery device (10, 10') includes an elongate tube (20), which is attached to a rigid housing (22,22'). A sensor (12), stored within a sterile environment comprising an interior of the sensor delivery device, has an attached signal line (16) that extends along the longitudinal axis of the delivery device and through its proximal end. The proximal end is open when the sensor is in its stored position. An eversible sheath (34) extends between the rigid housing and the signal line, sealingly separating the sterile environment (48) in which the sensor is stored from the open end of the rigid housing. To use the sensor, the signal line is moved into the rigid housing, causing the eversible sheath to turn inside out as the sensor is advanced through the catheter into its use position. The projection afforded by the eversible sheath permits the sensor to be withdrawn through the catheter and then reinsertd without introducing contamination. A probe stop (54) abuts an inner surface of a catheter fitting ( 17), precisely controlling the distance that the sensor extends beyond a distal end of the catheter.
Expandable Ring Closure Device
View pageUS Patent:
47212152, Jan 26, 1988
Filed:
Aug 28, 1986
Appl. No.:
6/901707
Inventors:
Francois X. Bertaud - Libertyville IL
Assignee:
Abbott Laboratories - North Chicago IL
International Classification:
B65D 102
US Classification:
215 32
Abstract:
A closure device for severing the frangible section between the cap and body of a blow-fill-seal plastic container comprising an expandable ring constructed and arranged to encircle the container cap, an outer ring having at one end internal threads compatible with the external threads located on the neck of the container body and a tamper proof overcap. Counterclockwise rotation of the outer ring transmits uniform upward pressure to the expandable ring which causes tension between the container cap and container body, rupturing the frangible line of weakness on the container, to permit opening of the container. Conversely, clockwise rotation of the outer ring causes compression to rupture the frangible line of weakness. Subsequent counterclockwise rotation opens the container. In either case the container cap is retained within the outer ring and is replaceable on the container.

Sterile Solution Container
View pageUS Patent:
44946635, Jan 22, 1985
Filed:
Jan 5, 1984
Appl. No.:
6/568325
Inventors:
Francois X. Bertaud - Libertyville IL
Hans J. Siedler - Gurnee IL
Hans J. Siedler - Gurnee IL
Assignee:
Abbott Laboratories - North Chicago IL
International Classification:
B65D 4132
US Classification:
215232
Abstract:
A tamperproof sterile solution closure system which will permit the machine assembly of the closure cap to the container without engagement of the threads of the cap with the container threads. The screw type cap member has internal threading, a tear-away portion and a skirt portion. The container has an abutment surface for sealable contact with the skirt portion and in a position such that the threads in the cap and on the neck are not engaged. To activate the closure, a tear-away portion is removed which will allow the threads to engage. Simultaneously, a contact portion on the cap will engage a weakened flange in the neck to cause it to be separated. A projection extending from the cap is positioned in an annular recess in the cap to serve as a captive means for the separated dome portion of the cap for replacement purposes.
