André SCHAAN CASAGRANDE has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11872100
    Abstract: Pincers for removing residual dental roots by the application of a contrary force on the mandible and maxilla on a pre-fixed screw. It is constructed in such a manner as to enable the strength of the operator to be multiplied and the final movement of the pincers to be reduced. The operator will need to apply minimal force and thus the procedure becomes simple and safe, thereby preserving the underlying bone structure and facilitating implant osseointegration. Likewise the device can be easily sterilized and assembled/dismantled easily because of the small number of moving parts. Further, there is no need for the mouth to be opened so widely, which results in less movement and less trauma caused by excessive opening of the patient's mouth, and it adapts to the irregular profile of support on the dental arch.

  • Publication number: 20230086779
    Abstract: A low-temperature turbocompressor structural arrangement for an internal combustion engine for using energy that is available but unused during operation to cool the air supplied to the engine by supercharging. The temperature of the air compressed by the compressor is reduced by a cooling system and the air is then conveyed to a further turbine actuated by the intake air flow of the engine. The structural arrangement may be mounted in full or in part, and also each component may be fitted into existing systems.

  • Publication number: 20210270181
    Abstract: The low-temperature turbocompressor structural arrangement for an internal combustion engine is a system for using the energy that is available but unused during operation of an internal combustion engine, for cooling the air supplied to said engine by supercharging, applicable to internal combustion engines of any type. The temperature of the air compressed by the compressor is reduced by a cooling system and the air is then conveyed to a further turbine actuated by the intake air flow of the engine, affording the benefits of enhancing engine performance levels, which may be used in order to obtain greater power or reduce consumption, since the denser air allows more fuel into the combustion chamber, achieving greater combustion, which increases the power-to-weight ratio, and the cooler air allows work at more aggressive compression and/or ignition advance ratios without problems of pre-ignition/pinking, thereby enhancing engine performance levels.
