Abstract

The present invention relates to the large-scale production of polymer nanocomposite with a matrix of ultra-high-molecular-weight polyethylene (UHMWPE) additivated with carbon nanomaterial (or nanofiller), and its use in ore transfer points. Suitable routes for processing polymer materials with ultra-high viscosity and additivated with 2D carbon nanomaterials in small fractions have been developed as part of the present invention to substantially improve mechanical, tribological and surface performance. Mixing in the molten state is the most industrially efficient and viable method for obtaining polymer nanocomposite materials. However, it is very difficult to achieve ideal dispersion and homogenization of this type of 2D nanomaterial with these matrices. In addition, polymers with high molar mass entail many inherent processing difficulties. The invention stresses that the pre-exfoliation of the nanofillers is essential to achieving significant dispersion of the nanofillers, enhancing the effects on the properties. The results presented demonstrate that the process developed produces nanostructured materials with suitable morphologies, and consequently excellent mechanical and surface properties.

Abstract

An apparatus for airborne electromagnetic surveying is provided, comprising a central hub defining an equatorial plane, a transmitter loop, and radials connecting the hub to the transmitter loop. The loop generally lies in a plane during flight, and comprises loop sections, some of which are connected with flexible joints allowing the loop to flex out of the plane during lift-offs and landings. A loop section comprises current conducting elements connected to current conducting elements of adjacent loop sections forming a transmitter loop circuit. A radial connects to the hub at a point that is substantially offset from the transmitter loop plane, thereby contributing to the stability of the transmitter loop connection point in an up-down direction relative to the hub. Additionally, a loop section comprising rigid conductive elements retained in a spaced-apart relationship by a frame member is also provided.

Abstract

An apparatus and method for sensing a leakage current along a primary conductor are provided. A first fault detection module is deployed at a first location along the primary conductor and a second driver module is deployed at a second location along the conductor, where the conductor passes through current sensors at each of the modules. The modules are further linked by a safety cable, which also passes through the current sensors. The driver module drives a compensation current in the safety cable to drive the net current passing through the driver current sensor to zero. The fault sensing module senses the net current passing through its current sensor. When the sensed current deviates significantly from zero, the fault sensing module generates a leakage current indication signifying a potential ground fault between the two modules.

Abstract

The proposed invention is a process for obtaining the ore dust suppressant resin with the chemical recycling of Poly thermoplastic polymer (Ethylene Terephthalate) or PET. It is proposed a method for obtaining the resin by using the depolymerization reaction methodology of the Poly polymer (Ethylene Terephthalate) obtained from post-consumption PET bottles, in the presence of cationic surfactant hexadeciltrimetrilamonio bromide (CTAB). The resin is thus obtained being subsequently added to the same PVP K-90 (Polyvinylpyrrolidone) as increasing load on the final viscosity of the resin. Other additives such as lignin extracted from plants such as leaves and tree branches may also be added, in this case, incorporated to make the resin more hydrophobic.
