Patent number: 11975069Abstract: Emulsion-based and micromolded (“MM”) or three dimensional printed (“3DP”) polymeric formulations for single injection of antigen, preferably releasing at two or more time periods, have been developed. Formulations are preferably formed of biocompatible, biodegradable polymers. Discrete regions encapsulating antigen, alone or in combination with other antigens, adjuvants, stabilizers, and release modifiers, are present in the formulations. Antigen is preferably present in excipient at the time of administration, or on the surface of the formulation, for immediate release, and incorporated within the formulation for release at ten to 45 days after initial release of antigen, optionally at ten to 90 day intervals for release of antigen in one or more additional time periods. Antigen may be stabilized through the use of stabilizing agents such as trehalose glass. In a preferred embodiment for immunization against polio, antigen is released at the time of administration, and two, four and six months thereafter.Type: GrantFiled: January 7, 2021Date of Patent: May 7, 2024Assignees: MASSACHUSETTS INSTITUTE OF TECHNOLOGY, TOKITAE LLCInventors: Ana Jaklenec, William Gates, Philip A.

Patent number: 7861617Abstract: A hand-operated swage device includes a first hand-operated actuator and a second hand operated actuator that, when actuated together, control the sequential operation of a clamping mechanism and a swaging mechanism of the hand-operated swage device. For example, the first actuator of the swage device is disposed on a first handle while the second actuator is disposed on a second handle of the swage device. To operate the hand-operated swage device, an operator grasps the first handle with one hand and grasps the second handle with his other hand to actuate both of the actuators in a substantially simultaneous manner. Actuation of both actuators controls sequential delivery of pressurized air to a first pneumatic device mechanically coupled to the clamping mechanism and to a second pneumatic device mechanically coupled to the swaging mechanism.Type: GrantFiled: March 30, 2007Date of Patent: January 4, 2011Assignee: Simonds International, Inc.Inventors: James S. Weatherly, Sr., Gregory S. Richardson, Paul Gardner, Norman Andrew Brown, Marc Elkins, Roy Erdwins, Robert L. Woods

Patent number: 7854183Abstract: A swage anvil includes a coupling portion that, when mated with a corresponding die of a swaging device, allows lateral positioning of the swage anvil (i.e., substantially parallel to a long axis of the saw blade) relative to the long axis of the saw blade. The swage anvil also includes a tooth contact face that substantially mirrors an angle of the back portion of each tooth of the saw blade. As such, after a manufacturer inserts the swage anvil into the swage device and laterally translates the swage anvil, the tooth contact face abuts the back portion of the saw blade tooth to support the tooth during a swaging procedure. With the aforementioned configuration of the swage anvil, translation of the swage anvil along a single axis provides support to the back portion of the saw blade tooth along two axes. As such, use of the swage anvil decreases the set-up time required in conventional swaging devices.Type: GrantFiled: March 30, 2007Date of Patent: December 21, 2010Assignee: Simonds Industries, Inc.Inventors: James S. Weatherly, Sr., Gregory S. Richardson, Paul Gardner, Norman Andrew Brown, Marc Elkins, Roy Erdwins, Robert L. Woods
