HEAT GENERATION APPARATUS AND HEAT GENERATION METHOD
HONEYCOMB BODY WITH NON-UNIFORM ELECTRIC HEATING.
Contactless temp. monitoring system for ferromagnetic vehicle brake disc - measures temp. dependent permeability in air gap of transformer, with min. permeability larger than one below Curie temp. and threshold permeability between min. and one, and compares actual and threshold values.
Calculating circuit for addition and subtraction - has main circuit having only one changeover tetrade or belt circuit or two special tetrade circuits and one shift register
Gas burner with holder for injector inlet to mixing duct - has injector inlet as separate, tubular part, engaging with play mixing duct
Pack of moisture tissues with game - has specially designed lid and container suitable for making sand sculptures, with dispenser lid under designed lid
Guide bar segments for knitting machines - have plastic moulded guide formations on each segments
Rotary anode bearing for X=ray tube - has roller bearing which is loaded with axially directed force to eliminate bearing play using magnetic parts mounted on end wall of vacuum tube and rotating shaft respectively.
Control switch for liquids or gases e.g. for sensing presence of flow - provides flow-operated switching piston with magnet and has housing contg. reed switch and second magnet for pulling first magnet against force of flow.
Verfahren zur kontrollierbaren und umweltschonenden Verbrennung von leicht brennbaren Stoffen sowie zur Durchführung dieses Verfahrens geeignete Verbrennungsvorrichtung
Plastics coupling flange with metal reinforcement - has part of reinforcement extending axially into support ring face of plastics ring collar for keyed engagement.
Continuous determn. of organic fluoro cpds. in gases - by hydrolysis in absorption soln. and fluoride ion determination, using fluoride selective electrode
Measuring quality of crystalline products, esp. sugar - by measuring head above prod. conveyor directs light beam onto prods., reflected light is sensed by probe and numerical quality value fed to computer
Board making machinery - has a mid installation machine to level and press one layer of the board
Workpiece quenching or heating in liq. medium - using gas introduction to increase quenching or heating rate
Tool changing device for machines tools - has arm with two grippers to hold tool elements parallel to spindle axis and has mechanism to provide synchronous sliding of grippers
Electric circuit design system method - storing component symbol information including position information with associated component identification information in application memory
Shaking of liq., paste or bulk medium
Light metal one-piece vehicle wheel - uses profile with nozzle-like opening to conduct cooling air to brake disc
