Blade (87627 Patents Found)
The present invention relates to an outer-diameter blade, an inner-diameter blade and cutting machines which respectively use the outer-diameter blade and the inner-diameter blade for cutting hard material, such as metal, ceramics, semiconductor single crystal, glass, quartz crystal, stone, asphalt or concrete, and a c...
A flap is attached to a rear end of a blade so as to be angularly displaceable. Displacement magnifying means magnifies the amount of displacement from an actuator to drive the flap. An input portion to which the displacement is applied from the actuator is expandably and contractibly supported by bellows. Likewise, an...
An anti-splintering system for sawing machines having a saw blade with a plurality of teeth, has components including an anti-splintering device positionable on a workpiece laterally from the saw blade in pressure contact with the latter in the region of the teeth, and at least one positioning device connectable to the...
Failures associate with bad hand pieces and blade failures in an ultrasonic surgical system are distinguished by monitoring the rate of change of the resonance frequency and the rate of change of the resonance impedance of the hand piece/blade as the drive frequency is changed. As the system reaches resonance, the cont...
A saw blade includes a base body and a plurality of groups of saw teeth. Each group of saw teeth is provided with a first section and a second section, wherein the first and second sections are adjacently positioned and respectively include a plurality of pre-cutting saw teeth, each of which has a first clearance angle...
A blade ( 10 ) for use in the slitting of a paper or board web has a hub part ( 11 ) and a blade part ( 15 ). The blade part ( 15 ) is releasably secured by means of securing members ( 12, 13 ) to the hub part ( 12 ). The securing members ( 12, 13 ) are formed so as to distribute and/or maintain the axial load enabling...
A first ultrasound medical instrument includes a medical ultrasonic blade having first, second and third blade portions. The second blade portion is more bendable than either of the first and third blade portions. A second ultrasound medical instrument includes a medical ultrasonic blade having a proximal blade portion...
In a developing assembly comprising a developer-carrying member and a developer quantity control blade kept in pressure contact with the developer-carrying member, the developer-carrying member has a deformation percentage D of 0.5% or less in the direction of pressure contact, and the developer quantity control blade ...
A preform for a turbine engine blade, comprising a main fiber preform obtained by three-dimensional weaving and comprising: a first longitudinal segment, suitable for forming a blade root; a second longitudinal segment, extending upwards from the first longitudinal segment and suitable for forming an airfoil portion; a...
When cold and in the non-coated state, the aerodynamic profile is substantially identical to a nominal profile determined by the Cartesian coordinates X,Y, Zadim given in Table 1, in which the coordinate Zadim is the quotient D/H where D is the distance of the point under consideration from a first reference plane P 0 ...
A method of maintaining a constant movement of a cutting blade of an ultrasonic waveguide includes providing an ultrasonic transducer operable to convert a received motional current into a movement of a cutting blade of an ultrasonic waveguide, a measurement circuit connected in a parallel configuration with the ultras...
A rotor blade for an aircraft includes an airfoil skin, an active element, and an actuator configured to operate the active element. A heat pipe is configured to promote heat transfer from the actuator to the airfoil skin. The heat pipe has a slope gradient such that a centrifugal force generated during rotation of the...
An electrosurgical forceps is provided with a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly operably coupled to the shaft includes a pair of first and second jaw members. One or both of the first and second jaw members is movable from an open configuration, to a clamping con...
A blade system of the present invention includes: a blade angle calculating part configured to calculate sum of a forwardly tilting angle of a vehicle body with respect to a reference surface and a blade lifting angle of a lift frame with respect to a reference position; a difference angle calculating part configured t...
An airfoil of a turbine blade is provided. At least one sensor element is integrated into the material of the turbine blade airfoil in order to directly determine the progress of erosion of the turbine blade airfoil. Various methods for directly determining the progress of erosion of an airfoil of a turbine blade are a...
