DEFINING AND CHECKING CONFORMANCE OF AN OBJECT SHAPE TO SHAPE REQUIREMENTS

PRINTING PLASTIC CONTAINERS WITH DIGITAL IMAGES

Driving device for controlling opening of e.g. shutter type closing system, has transmission unit with cams that provide idle motion for unit with respect to casements in initial or final opening or closing control phase of casements

Gearbox for motor vehicle, has hollow primary shaft comprising gear teeth with one tooth interlinked with two pinions that are mounted freely in rotation around secondary shafts that are provided with drive pinions

Aqueous dispersion, useful in cross-linking to form an elastomer, comprises an organic phase (polyether silyl) and emulsifier dispersion

Remote motor vehicle access control unit e.g. electronic badge, localization assisting method for motor vehicle, involves controlling identification code verification and alarm unit activation upon reception of localization request signal

Eye validity verifying method for identifying iris of eye, involves lighting zone of iris by light beam issued from acquisition device and analyzing zone to decide validity of eye, where optical characteristics of beam are variable in time

Flat object e.g. microelectronic circuit, measuring method for object characterization, involves analyzing reflected excitation beam polarization for measurements of beam at azimuthal angles and characterizing model object with parameters

Multiphase fluid e.g. petroleum effluent, composition determining method, involves finding volume fractions by minimizing distance between measured attenuation and phase shift pair and attenuation and phase shift pair determined by model

Lens e.g. ophthalmic lens, refraction characteristics e.g. spherical power, measuring method for e.g. optician, involves maintaining lens fixed with respect to lighting unit, where position of measurement axis is variable

Fluid or grainy body e.g. food product, presence detecting method for e.g. industrial oven, involves transmitting signal to radiometer based on radiometric signal, and evaluating, by evaluation unit of radiometer, body presence information

Carburetor system for working equipment e.g. brush cutter, has starting lever locked in rest position relative to actuating direction, and unlocked in unlocking direction so that lever movement in actuating direction is freed

Printed ticket e.g. checkout ticket, availing device for supermarket checkouts, has three deflector surfaces cooperating with three respective rollers to guide ticket from blades of printer to ticket collection channel

Food container for gateau, has base formed by cover support part and detachable serving plate

Secondary stage regulator for breathing apparatus, has throttle valve axially moved with respect to seat through guiding exerted by pivot so that impact between seat`s edge and frontal seal joint is distributed on circumference of edge

Activated shock absorber for bicycle, has fixation unit mounted near upper end of cylinder, sealing joint mounted above fixation unit, and locking actuator that controls piston rod assembly to activate or deactivate shock absorbing function

New N-hydroxy-N'-phenyl thiourea derivatives are melanine synthase inhibitors useful to e.g. prevent the appearance of pigmentary spots or depigmentation marks on the skin
