Title: Rapid gold-labeled detection card capable of simultaneously detecting multiple disease antibodies
Inventor: LIN GUIHUA
IPC: G01N33/68
Filed: 2017-09-07
Granted: 2017-12-21
Abstract: The present invention relates to the field of rapid gold-labeled detection cards, in particular to a rapid gold-labeled detection card capable of simultaneously detecting multiple disease antibodies. The rapid gold-labeled detection card includes a sample area, a plurality of rapid gold-labeled detection cards for different disease antibodies are respectively arranged at the periphery of the sample area, the sample area is of a slot structure, a plurality of through holes are distributed on the lower part of the slot wall of the sample area, the sample area is communicated with the outside of the slot wall through the through holes, sample-injecting end water absorption membranes of the rapid gold-labeled detection cards contact with a sample in the sample area through the through holes, the middle of the slot bottom of the sample area is protruded and inclined towards an edge. As known from the above structure, the rapid gold-labeled detection card capable of simultaneously detecting multiple disease antibodies not only selects a sample whose various disease antibodies need to be simultaneously detected as required but also simultaneously performs virus antibody detection of these infectious diseases on one sample, and is simple to operate, few in sample amount and strong in product applicability.

Title: Vehicular motion assessment method
Inventor: CASTIGNANI GERMAN
IPC: G07C5/08
Filed: 2018-04-09
Granted: 2019-10-11
Abstract: A vehicular motion assessment method (Fig. 1) comprises: capturing motion observations on-board a vehicle (12), the motion observations including timestamped vehicle positions; logging the motion observations; map-matching the motion observations so as to identify, for each vehicle position a road link of a road network stored in a map database (18) as well as a map-matched position on the road link; contextualizing the motion observations by augmenting them with situational data obtained by querying the map database (18) or another geographic information database; determining, based on the contextualized motion observations, whether the vehicle (12) was exposed, during the trips, to unsafe driving situations; and communicating one or more risk scores indicative of accident probability, calculated based on determined exposures to unsafe driving situations.

Title: Diamond Enriched Insulation Paper for Cooling Improvement of an Electrical Machine
Inventor: KOLONDJOVSKI ZLATKO
IPC: H01B3/52
Filed: 2018-07-24
Granted: 2020-01-24
Abstract: The thermal conductivity of the electrical paper insulation could be increased if the paper material is either enriched or fully substituted by a material with higher thermal conductivity. Diamond as enrichment material will be the right choice because besides the high thermal conductivity, it also acts as an excellent electrical insulator and has good mechanical properties. The thermal conductivity of the diamond is kdiamoncf=22QQ [W/mK], that is even more than 7000 times higher than the paper material. Diamond enriched insulation papers have not existed before this invention. In the proposed structure the diamond particles are held in place also by the fibrous substance of the paper itself, without the need of a holding matrix material by default, as shown in Fig 1. The diamond particles mixed in the paper can also penetrate the paper across creating a thermal bridge between the insulated parts while maintaining strong electrical insulation.

Abstract: A high-temperature superconductor of the composition Bi2(Sr,Ca)3Cu2O8+x having a strontium:calcium ratio of from 5:1 to 2:1 and a value for x of between 0 and 2 is prepared by vigorously mixing the oxides and/or carbonates of bismuth, strontium, calcium and copper in a stoichiometric ratio. The mixture is heated at temperatures of from 870 to 1100 DEG C until a homogeneous melt is formed. The melt is cast in chill moulds and allowed to solidify therein. The castings removed from the moulds are conditioned at 780 to 850 DEG C for from 6 to 30 hours. The conditioned castings are finally treated for 6 hours at a temperature of from 600 to 820 DEG C in an oxygen atmosphere. 
<??>The castings can be converted into mouldings of any desired dimensions by mechanical methods before conditioning.

Abstract: A decoration correction method for a form-and-seal unit (1) for producing sealed packages of a pourable food product from a tube (2) of packaging material fed along a feed path, and having two pairs of jaws (7) movable along the feed path and opened and closed so as to travel, cyclically and alternately with each other, along a form-and-seal portion along which the pairs of jaws (7) are closed and travel integrally with the tube, and along a repositioning portion along which the pairs of jaws open and move with respect to the tube (2). To make a decoration correction, a nominal trajectory (P) of the jaws (7) is modified along the repositioning portion on the basis of a position error of the tube (2) with respect to a nominal position. A first solution provides for correcting the travel of the jaws by selectively modifying the amplitude of the trajectory; and a second solution provides for correcting the phase of the jaw trajectory. <IMAGE>
