Title: Self-locking power component for orthodontic appliances
Inventor: INMAN DONAL P
IPC: A61C7/00
Filed: 2004-04-16
Granted: 2011-09-13
Abstract: A force adjusting mechanism for an orthodontic appliance (10) wherein the appliance functions to move teeth and/or to expand the dental arch. The mechanism includes a shaft (40) operatively coupled at opposite ends between a first portion of the appliance (10) which is anchored in the patient's dental arch and a second portion of the appliance (10) which applies force to one or more of the patient's teeth. A lock (42) is slidable along the shaft (40) to compress a spring (32) between the lock (42) and the second portion of the appliance (10). Co-operating structures on the shaft (40) and on the lock (42) provide a unidirectional ratchet movement of the lock (42) along the shaft (40). Thus, the lock (42) may be advanced one step at a time in one direction only, preferably manually using an implement for engaging the lock, to compress the spring (32) to apply force to one or more of the patient's teeth.  Advantageously, this may be done by the patient or a parent or guardian without the need for an office visit to a clinician.

IPC: C12N1/20
Filed: 2004-06-23
Granted: 2012-10-02
Abstract: The present invention provides a method for purifying bacterial minicells that involves subjecting a sample containing minicells to density gradient centrifugation in a biologically compatible medium. The method optionally includes a preliminary differential centrifugation step and one or more filtration steps. The invention also provides a method for purifying bacterial minicells in which a sample containing minicells is subjected to a condition that induces parent bacterial cells to adopt a filamentous form, followed by filtration of the sample to separate minicells from parent bacterial cells.  The inventive methods optionally include one or more steps to remove endotoxin from purified minicell preparations, and/or treatment of purified minicell preparations with an antibiotic. Additionally, the invention provides purified minicell preparations, prepared according to the foregoing methods, and containing fewer than about 1 contaminating parent bacterial cell per 107, 108, 109, 1010, or 1011 minicells.

Abstract: The present invention is directed to methods of forming sidewall-functionalized carbon nanotubes, wherein such functionalized carbon nanotubes have hydroxyl-terminated moieties covalently attached to their sidewalls.  Generally, such methods involve chemistry on carbon nanotubes that have first been fluorinated. In some embodiments, fluorinated carbon nanotubes ("fluoronanotubes") are reacted with mono-metal salts of a dialcohol, MO-R-OH, where M is a metal and R is hydrocarbon or other organic chain and/or ring structural unit. In such embodiments, -O-R-OH displaces -F on the nanotube, the fluorine leaving as MF. Generally, such mono-metal salts are formed in situ by the addition of MOH to one or more dialcohols in which the fluoronanotubes have been dispersed. In some embodiments, fluoronanotubes are reacted with amino alcohols, such as being of the type H2N-R-OH, wherein -N(H)-R-OH displaces -F on the nanotube, the fluorine leaving as HF.
