Water e.g. hot water, economizer for use during washing e.g. fruits, has pulse control device interrupting water flow when pulse is applied on outlet nozzle along flow axis, and restoring water flow when another pulse is applied on nozzle
Guide slot forming method for e.g. intra-optical connections of silicon chip, involves filling trenches with silicon, and carrying out annealing of silicon oxide layer after performing formation, graving or filling steps
Courier article postage method for courier processing field, involves associating postal impression to elaborated digital signature from fixed and/or variable data, which only has printed code extracted from three-dimensional structure
Transmission resource managing method for e.g. worldwide inter-operability for microwave access network, involves selecting specific format for each terminal from list of transport formats, and allocating frequency band to each terminal
Dish e.g. flatware, washer for use in washery field, has heat pump provided with condenser for heating water that treats dishes and with evaporator for cooling outlet air from air mixer, and air/water heat exchanger cooling air from tunnel
Filtration device for cooling lubrication oil of e.g. car engine, has filter medium conducting heat in filtration module, and chain of conducting elements including ends in contact with filter medium and heat transfer fluid, respectively
Mixer for producing heavy crude oil-in-water emulsions, comprises cylindrical tank containing cylindrical bar of which axis of revolution is parallel, and unit for adjusting position of bar in tank for obtaining maximum shear position
Three-dimensional object e.g. nacelle, positioning assisting method for use during design phase of aircraft, involves acquiring data connected to object position for model with constraint modeling, and evaluating constraint based on data
