Abstract:
The invention disclosed is a self-propelled aircraft undercarriage for driving an aircraft on the ground, comprising: an axle; a strut supporting said axle; at least one wheel rotatably mounted on said axle; and drive means for driving said at least one wheel; characterized in that said drive means is disk shaped and is external to said wheel. In one embodiment of the invention, said drive means is mounted on said axle between said strut and said wheel. In a second embodiment, said drive means is mounted on said axle, on the side of said wheel furthest from said strut.
Abstract:
The embodiment described herein are related nanoemulsions comprising botulinum toxins. In one embodiment, the nanoemulsions are prepared by high pressure microfluidization and comprise a particle size distribution exclusively between 10 and 300 nm. The nanoemulsions contemplated by the present invention are useful for the cosmetic and medical treatment of muscular contracture states. For example, botulinum toxin may relax facial muscles such that skin wrinkles become smoother and less noticeable. Further, the present invention contemplates a cosmetic formulation that may be self-administered, for example, in the privacy of one's home and without medical supervision.
Abstract:
The present invention provides methods for assessing the activity of topically administered chemodenervating agents. In some embodiments, methods for assessing the activity of topically administered chemodenervating agents involve determining the extent of inhibition of acetylcholine release near the site of administration. In some embodiments, methods for assessing activity of topically administered chemodenervating agents involve observing a reflex motion of a limb of a subject.
Abstract:
The present invention relates to the use of stator windings of an induction machine to provide both rotation of the rotor and active rotor positioning within the stator frame by modification of the magnetizing current component in the D-Q plane of the rotor applied transformed to the AC waveform current of the stator windings according to an X-Y direction describing a rotor repositioning requirement.
Abstract:
In the present invention, several polyphase devices are connected together: an inverter, and electrical rotating machine, and a resistive load or braking resistor. The purpose of the resistive load is to dissipate excess electrical power which may be produced when the inverter acts to slow down the rotating machine, causing the rotating machine to act as a generator. In common art, this resistive load is a single DC resistor coupled to the DC link of the inverter via a separate resistor control transistor. In the present invention, the resistive load is a mesh connected array of resistors, and is electrically connected to the same inverter output terminals that the rotating machine is connected to. When it is desired that the resistors absorb energy, for example from a braking operation, then the harmonic content of the inverter output is adjusted, thus placing voltage differences across the resistor array and causing current to flow in the resistors.
Abstract:
The present invention provides nanoparticle compositions including one or more nucleic acids. The present invention achieves delivery (particularly transdermal delivery) of such nucleic acids without the need for nucleic acid modification, or for use of chemical or mechanical abrasion or disruption of skin.
Abstract:
A drive system with harmonic drive designed to meet the high power and torque requirements required to drive an aircraft independently on the ground is provided. The drive system includes an electric motor driven by a harmonic drive assembly that may be configured to be integral with the motor. This drive system with harmonic drive can be effectively installed in an existing aircraft nose wheel or main wheel without changes to other components.

Abstract:
The invention consists of a ring motor, in which a first ring forms a toroidally wound stator and a second ring forms the rotor. A turbine is fixed to the rotor ring. The invention is specifically targeted towards the environment inside a gas turbine, in which hot gases may permeate the space between rotor and stator.

In the present invention, several polyphase devices are connected together: an inverter (420), and electrical rotating machine (440), and a resistive load or braking resistor (430).

In common art, this resistive load is a single DC resistor coupled to the DC link of the inverter via a separate resistor control transistor. In the present invention, the resistive load is a mesh connected array of resistors, and is electrically connected to the same inverter output terminals that the rotating machine is connected to.
