20140146162 | Optical Video Measurement System Having Interchangeable Optics - An optical video measurement system for comparing a manufactured part against a representation of the manufactured part. The measurement platform system includes an optical video system for capturing images of the manufactured part. The optical video system includes a camera configured to capture one or more images of the manufactured part. The camera is configured to cooperate with one of several interchangeable lens assemblies for providing optics for the camera. The camera is configured to receive and retain one of the several interchangeable lens assemblies by way of a bayonet mount, wherein each of the interchangeable lens assemblies includes a male side configured to be received within a female side of the camera. The video measurement system further includes a mounting assembly configured to receive and retain a portion of each of the interchangeable lens assemblies and maintain alignment of each of the interchangeable lens assemblies with the camera. | 05-29-2014 |

20150142683 | METHOD OF ANTI-COUNTERFEIT IDENTIFICATION - The method of anti-counterfeit identification includes establishing a tracking platform to render and store enterprises' registration information (including registered names and telephone numbers) and security codes. A client connected to the tracking platform for inquiry is established, and manufacturers print on their products corresponding anti-counterfeit phone numbers, corporate security codes and commodity security codes obtained from the anti-counterfeit tracking platform. Commodity security systems are established by manufacturers for storage of commodity security codes and inquiry records. In each procedure of a commodity sales process, commodity security directly feeds back to corresponding manufacturer. Inquiry can be made via telephone or mobile, having reduced complexity of anti-counterfeit inquiries. Information inquired will be rendered based on corporate names registered on the anti-counterfeit tracking platform, which radically eliminates the possibility of falsification by counterfeit and shoddy product manufacturers. | 05-21-2015 |

20150014224 | HIGH GRADIENT, OIL-COOLED IRON REMOVAL DEVICE WITH INNER CIRCULATION - A high-gradient internal-circulating oil-cooled Magnetic Separator, includes magnetic system coils, an internal-circulating oil path system, an external-cooling system and an oil conservator. The magnetic system coils are used for generating excitation magnetic field to achieve the iron-absorption function, the magnetic paths of the magnetic system coils being an open magnetic path structure. The internal-circulating oil path system is used for allocation and collection circulation of transformer oil. The external-cooling system is used for heat dissipation of transformer oil to achieve internal heat dissipation balance. The oil conservator is used as a supplementary container for the transformer oil expansion during the apparatus's operation. An internal-circulating structure is employed, and external-circulating pipes are simplified, circulating resistance in oil paths being reduced, problems including complex interference in oil paths arrangement, low circulation efficiency, leakage at welding spots, etc. being avoided, ensuring normal operation, and enhancing efficiency of iron removing. | 01-15-2015 |
