A grinding wheel dressing device is mounted, together with a grinding wheel head, on the cut feed carriage, and the grinding wheel head, the grinding wheel dressing device and a direct sizing device which form a group are arranged in a manner to move in the axial direction of the spindle with respect to the head stock, whereby grinding of the inner peripheral surface of a workpiece can be effected.

An internal mixer for kneading and rolling includes a mixing chamber containing two parallel spaced shafts. Kneading blades and arcuate roller surfaces are provided on the outer peripheries of the shafts. The arcuate surfaces are so disposed on the shafts such that a gap is formed therebetween when in their innermost positions. The arcuate surfaces and kneading blades are disposed serially in the peripheral direction on the shafts. The shafts rotate in opposite directions and so as to provide th...

An internal hinge for use with first and second members such as the front and back legs of ladders in which there is a generally tubular means having a first portion adapted to be inserted into an aperture in the first member and a second portion adapted to be inserted into a second aperture in the second member. The apertures are aligned and adjacent one another and in the first portion there are two peripheral slots opposite one another through which a rigid pin passes, the ends of the pin bei...

A pair of pliers is equipped with an expander unit that spreads the handles so that the jaws will forcibly grip objects from the inside. External teeth on the jaws aid in gripping.

A one-piece paperboard internal partition structure including a center horizontal wall and intersecting pairs of longitudinal and transverse vertical walls disposed on opposite sides of the horizontal wall.

A mixing of mixing machine comprises a mixer body having a mixing chamber and a material inlet through which a material to be mixed is loaded into the chamber, a fluid-operated cylinder having a piston rod on which a floating weight is mounted for movement together with the piston rod between lifted and lowered positions, a support structure for supporting the cylinder for movement between an operative, in which the floating weight is in register with the material inlet, and a stand-by position ...

An internal clock generator includes a detector, an internal signal generator and a clock output unit. The detector detects a transition point of an external clock signal and outputting a detection signal. The internal signal generator generates an internal signal in response to the detection signal and a pulse width control signal. The clock output unit outputs an internal clock signal having a pulse width, which is set based on the internal signal. A transition point of an external clock signa...

A mobile terminal includes a terminal case, a main PCB inside the terminal case mounting various circuit components thereon, and an internal antenna fixed on the main PCB. The internal antenna can transmit and receive radio waves bearing voice and image information to and from the main PCB and shield electromagnetic wave generating parts mounted on the main PCB. Thus, embodiments of an internal antenna, a mobile terminal and methods thereof can reduce size and costs, and can shield RF elements o...

A method for providing supplemental internal air cooling to a multi-cylinder internal combustion engine. The method involves deactivating the fuel injector to one cylinder for a predetermined time period or temperature decrease, based upon engine operating conditions, and then reactivating the fuel injector. This results in cool air being pumped through the fuel-deactivated cylinder by the reciprocating action of the piston therein, which air-cools the walls, piston, and head of that cylinder fr...

The invention relates to the internal exhaust-gas recirculation in an internal combustion engine with gas exchange valves periodically controlled by a camshaft (22) in accordance with the four-stroke principle, in which, during the gas exchange exhausting of exhaust gas from the respective cylinder (1) into the exhaust duct (5), an intake valve (2) associated with the respective cylinder (1) is open in a crank angle range after top dead center of the ignition of the gas mixture present in the cy...
