Abstract: The present invention relates to a system and method for cultivating an seaweed, preferably Sarcothalia crispata, including releasing spores from seaweed reproductive tissue, inoculating a substrate with spores, germinating the spores and growing seaweed from the germinated spores. The invention also relates to a harvested batch of seaweed having a lambda carrageenan content of at least about 80 wt.% based on mass of all carrageenans and wherein the mass of seaweed is at least 100 kg, more preferably at least 500 kg and most preferably at least 1000 kg.

Abstract: This device, designed for cutting the grooves of pneumatic tire treads, includes a re-grooving tool having two distal cutting points that creates grooves in the tire treads having two subgrooves. The grooves improve the fuel efficiency of vehicle and the subgrooves improve channeling and clearance of rain, snow, mud, and other hazardous materials on the road.

Abstract: A method for welding multiple workpieces together includes applying a force to the multiple workpieces, generating ultrasonic vibration, transferring the ultrasonic vibration to the multiple workpieces to breakdown an oxide layer, generating an electric current, transmitting the electric current to heat up the workpieces, and synchronizing the ultrasonic and resistance heating operations. A welding system includes an ultrasonic vibration unit that generates an ultrasonic vibration and transfers the ultrasonic vibration to multiple workpieces to breakdown an oxide layer, a resistance heating unit that generates an electric current and transmits the electric current to heat up the workpieces, a workpiece mount that includes electrodes configured to receive the generated current and/or clamp the multiple workpieces during a welding process, and a controller configured to synchronize an operation of the ultrasonic vibration unit and an operation of a resistance heating unit.
