A61K 31/10

US Classification:

568 22, 568 23, 514707, 514708

Abstract:

The invention provides enantiomers of ajoene and derivtives of Z(−)-ajoene. The derivative of Z(−)-ajoene are useful for modulating integrin-mediated functions, for treating disorders, diseases or conditions in which integrins play a role, and for treating tissues to improve their condition for a subsequent use, such as transplantation.

Appl. No.:

10/520776

Inventors:

John B. Davidson - Chicago IL, US

Assignee:

JODA Enterprises, Inc. - Chicago IL

International Classification:

B25B 23/16
B25G 1/00

US Classification:

8117785, 811772, 811778, 8117785

Abstract:

A tool of the type having a drive stud for receiving and releasing a tool attachment includes an opening in the drive stud and a locking pin movably mounted in the opening. The opening defines first and second ends, and the first end of the opening is located at a portion of the drive stud constructed for insertion into the tool attachment. An actuating member is movably positioned on the drive stud, and the actuating member defines a sliding surface that engages the pin. A first spring biases the sliding surface toward the pin, and a second, weaker spring biases the pin toward the sliding surface. The first spring reacts against a ring that is disposed between the spring and a shoulder formed on the tool. The shoulder extends away from the longitudinal axis of the drive stud by a lesser distance than the spring or the ring.

Appl. No.:

10/580775

Inventors:

John B. Davidson - Chicago IL, US

Assignee:

JODA Enterprises, Inc. - Chicago IL

International Classification:

B25B 13/46

US Classification:

81 60, 81 581

Abstract:

A ratchet wrench has a drive-stud element with a drive stud at a first end and a drive recess at a second end. The drive-stud element is coupled with a one-way drive transmitting wheel to rotate in unison therewith about an axis. The wrench can have a centering element that resists movement of the one-way drive transmitting wheel in at least one direction away from the axis. The drive-stud element and the one-way drive transmitting wheel can be separately formed. A method is also disclosed for operating a ratchet wrench with a drive-stud element with a drive stud at a first end and a drive recess at a second end.

Appl. No.:

12/290638

Inventors:

John B. Davidson - Chicago IL, US
C. Robert Moon - Joliet IL, US
George F. Charvat - East Troy WI, US

Assignee:

Joda Enterprises, Inc. - Chicago IL

International Classification:

B25B 23/16

US Classification:

8117785

Abstract:

Coupling mechanisms for engaging and releasing a tool attachment such as a socket from a drive element include an engaging element and an actuating element. The actuating element can include a collar or other manually-accessible part, and various features allow for a relatively small outside diameter for the collar or other part. These features include configuring the actuating element to contact the engaging element within the drive element, placing the biasing elements within the drive element, and forming guides for parts of the actuating element within the drive element Also, the engaging element can move along a direction that is oriented at an oblique angle to the longitudinal axis of the drive element, in whole or in part. The engaging element can have a first part that moves obliquely in the drive element and a second part that moves radially in the drive element to engage the tool attachment.

Assignee:

Joda Enterprises, Inc. - Chicago IL

International Classification:

B25B 23/16

US Classification:

8117785, 8117775

Abstract:

A universal joint includes first and second parts interconnected by a coupling element, and a coupling mechanism for detachably engaging tool attachments such as sockets. The disclosed coupling mechanisms include an engaging element and an actuating element. The engaging element can include a pin, and the pin can be oriented either obliquely or longitudinally in the drive stud of the universal joint. The actuating element can include a collar and a central portion that crosses the central longitudinal axis of the drive stud. The central portion can be offset along the longitudinal axis toward the coupling element, and the actuating element can be configured to extend into an aperture formed by the coupling element and the second part of the universal joint.
