The inverse Class-F power amplifier (PA) comprises an appropriately biased GaN active device, input matching network, and output wave-shaping and matching network. The novel design of the wave-shaping and output matching network ensures minimal overlap of the drain voltage and current waveforms, and...

The biological sand filtration system is a simple, cost-effective solution used to improve the quality of winery wastewater for reuse (e.g., for beneficial irrigation). The system can operate entirely off-grid using solar panels and gravity for energy. Microbial communities within the system degrade...

This technology involves a method for generating hydrogen in an electrolysis cell. A proton exchange membrane (PEM) is used to separate anode and cathode chambers of the cell. The space between the anode and the PEM is filled with aqueous sulfuric acid. In use, gaseous sulphur dioxide is fed to the...

This process is used for generating hydrogen by providing a hydrogen chemical carrier in the presence of an active catalyst in a reactor vessel and elevating the temperature inside the reactor by electromagnetic process to allow a dehydrogenation reaction to generate hydrogen. The active catalyst is...

The invention relates to a low-cost, portable, self-aligning rooftop wind turbine designed to capture moderate-velocity wind and generate electricity efficiently for household use. Current large-scale wind turbines in South Africa are located far field and the energy generated must be transported...

The technology relates to an upright tubular fixed-bed reactor body comprising a heat -dissipating pipe, which extends from the reactor tube wall, to ensure that heat is effectively transferred in highly exothermic reactors such as Ficher-Tropsch, which are prone to heat build-up.   The heat pipe is...

This invention relates to an alternate oxidant for a delay composition, and more particularly to a delay composition including a fuel and an oxidant in the form of antimony hexitatridecoxide having the formula Sb6O13. The invention also relates to the use of antimony hexitatridecoxides as an oxidant...

The invention relates to the scavenging of flavour compounds, typically undesirable or off-flavours, from a liquid beverage or foodstuff. In particular, the invention relates to the use of proteins for scavenging flavour compounds associated with dairy products, such as those which arise from heat...

The compound 1, 3, 6, 8–tetrahydroxy –2, 5-dimethoxyxanthone (formula (I)), having the ability to treat sexual dysfunction or erectile dysfuncion, is claimed. A process for obtaining a plant extract containing this compound, an extract and the use of this compound or extract in manufacturing a...

Invention

The invention relates to a food ink for use in a 3D printing process for the manufacture of food items, using extrusion-based printing techniques.

Problem solved

The printer can make foods with elaborate decorations and designs more easily than doing it by hand. It can enhance diversity...
