Patent number: 10436265Abstract: A rotor disk assembly includes a rotor disk. The rotor disk includes a first rotor lug, a second rotor lug circumferentially spaced from the first rotor lug and defining a slot therebetween. The slot is located on a radially outward portion of the rotor disk and the slot has an undercut engagement portion defined by the first rotor lug and the second rotor lug. The undercut engagement portion is positioned circumferentially on the rotor disk to engage a rotor clip.Type: GrantFiled: August 10, 2017Date of Patent: October 8, 2019Assignee: GOODRICH CORPORATIONInventor: John A. Stevenson

Patent number: 5718689Abstract: A free-standing safety cap for storing contaminated medical instruments includes a sleeve, a stand on one end of the sleeve and a one-way locking mechanism on the other end. A user places the cap on a flat surface so that it is free standing and, without grasping the cap, inserts the instrument's contaminated sharp end into the cap. The one-way locking mechanism permanently secures the contaminated sharp end inside the cap. The stand can be formed with an opening for accessing the sleeve so that the cap can used for storing both the sterile and the contaminated instrument. This greatly reduces the risk of accidental puncture wounds to the cleaning and waste disposal personnel.Type: GrantFiled: July 10, 1996Date of Patent: February 17, 1998Inventor: John A. Stevenson

Patent number: 5554129Abstract: A free-standing safety cap includes a first compartment for temporarily securing an unused medical instrument and a second compartment for permanently securing a used medical instrument. The instruments have a sharp end, and are fitted with a hub. The first compartment has an opening through which the unused instrument can be removed. A stand supports the cap in a position in which an opening in the second compartment is exposed to receive the used instrument without the user having to hold the cap. A locking mechanism, preferably one-way, is provided for engaging the hub and permanently securing the sharp end of the used instrument inside the second compartment.Type: GrantFiled: November 28, 1994Date of Patent: September 10, 1996Inventor: John A. Stevenson
