A wood lathe includes a driving pulley unit disposed around a rotating inner rod, a driven pulley unit disposed around an output shaft that is used to rotate a workpiece, a V-belt unit trained on the driving and driven pulley units, and a speed-adjusting unit. When a rotary knob is rotated, amovable inner half of the driven pulley unit moves toward or away from a fixed outer half of the driven pulley unit so that the V-belt unit moves a movable outer half of the driving pulley unit away from or toward a fixed inner half of the driving pulley unit. As such, the position of the V-belt unit can be adjusted relative to the driving and driven pulley units to change the rotational speed of the output shaft.

An industrial fluid circulating system having at least one fluid circulation circuit, includes a plurality of pumps connected in parallel to circulate the fluid through each of the fluid circulation circuit, a separate motor driving each pump, a load detector to sense operating loads on the system and each circuit, and a speed control to vary the speed of each motor to thereby vary the pumping capacity of each pump in response to the detected load on the system, each pump of each respective circuit running simultaneously at a substantially similar speed or a predetermined equal reduced speed of the respective circuit or an almost equal reduced speed or a similar reduced speed.

The present invention provides a wire saw which cuts a workpiece using a cutting wire and is capable of adjusting wire tension with high responsiveness. The wire saw includes first and second workpiece cutting units 1A and 1B. Each of the workpiece cutting units 1A and 1B includes a pair of guide rollers 10a and 10b around which a wire W is wound to form a workpiece-cutting wire group. The wire saw further includes a tension detector 18 which detects tension in the wire W between the workpiece cutting units 1A and 1B, and a control device 50. The control device 50 changes a rotational speed of the guide rollers 10a and 10b of at least one of the workpiece cutting units based on the tension detected by the tension detector 18 so as to keep the tension within an acceptable range.

When a rotational shaft of a gear speed reducer is rotated, a small-diameter gear of a first gear is held in mesh with first internal teeth of a fixed gear and a large-diameter gear of the first gear is held in mesh with second internal teeth of a second gear. The first gear and the second gear comprise cycloidal gears, respectively, and transmit rotational drive power to the second gear. The rotational drive power is output from an output shaft of the second gear. The gear speed reducer has a default mechanism for holding the output shaft at a predetermined angular position when an electric signal applied to an actuator is interrupted, and a self-lock function for preventing drive power applied from the output shaft from being transmitted to the actuator.

A method for ascertaining a rotational speed parameter for determining a setpoint torque for driving a drivetrain. The drivetrain comprises a first and at least one second drive assembly for driving a hybrid vehicle. The first drive assembly can be coupled to the drivetrain by means of a clutch. The second drive assembly is mechanically coupled to the drivetrain. When the hybrid vehicle is being driven by means of at least the first drive assembly, the rotational speed parameter corresponds to the value of a shaft rotational speed. When the hybrid vehicle is being driven only by means of the second drive assembly, the rotational speed parameter corresponds to the value of a determined rotational speed.

An apparatus for shot peening blade mounting areas on a disc of a rotor includes a peening nozzle unit which streams shot peening media along a longitudinal axis. The unit includes a nozzle outlet which extends at least partially in a circumferential direction of the unit, and a deflection arrangement with a deflection area for the media. The deflection area is at least partially cone or half-hyperboloid shaped, such that the media passes the nozzle outlet over an angle range in circumferential direction after being deflected by the deflection arrangement. A method for shot peening the blade mounting areas positions the unit in a slot profile of a blade mounting area, and guides the unit along the contour of the slot profile with the nozzle outlet facing the contour of the slot profile to approximately uniformly peen the contour of the slot profile.

An automated variable speed control system for a cutter head of a dredging cutter has a cutter head and a pump. The pump pumps cuttings from the cutter head through a cuttings discharge line. A sensor monitors amperage draw of the pump. A controller controls speed of movement of the cutter head based upon data received from the sensor. The controller increases a speed of movement of the cutter head through the materials when the amperage draw of the pump falls below the determined amperage range and the controller decreases the speed of movement of the cutter head through the materials when the amperage draw of the pump exceeds the determined amperage range.

A wheel speed sensor for a motor vehicle can be supplied with an operating voltage by a control device. The control device has a load resistance with a load resistance value. An operating voltage can be at a voltage input by the control device. An electrical circuit is designed to determine a turn-on or a turn-off voltage value according to the load resistance value. An operation control is designed to transfer the wheel speed sensor into a normal operation using the operating voltage, when the turn-on voltage value is exceeded, and to transfer the wheel speed sensor into an emergency operation using the operating voltage, when a turn-off voltage value is not met. In emergency operation only a low constant signal level is emitted.

In this podcast, The Evil Chocolate Cookie gives us a demonstration of the Tap Strap 2, a single handed all-in-one wearable keyboard, mouse & air gesture controller.

Tap is a wearable keyboard and mouse that enables you to type, mouse and control any Bluetooth enabled device, using any surface and in any position. Tap has accelerometers built into each finger ring, which register which fingers you are tapping and sending the associated letter, number, symbol, or macro to a paired Bluetooth device.

Tap is the only ergonomic solution that allows you to type in any position that is comfortable to your specific body without being bound to a desk. Tap’s design takes stress off your median nerve, allowing for hours of typing without strain. Tap also allows you to write without hunching forward, which causes posture problems as well as neck, shoulder and back pain.

Learning to Tap takes about 2 Hours – which is approximately 10 times faster than it takes to learn to QWERTY touch-typing. You learn to Tap using finger combinations, not key locations, making it usable in a variety of situations where you could not use a QWERTY. The fastest way to learn is by playing our free TapGenius Learning Game, which takes you through the Tap Alphabet using a series of fast, engaging challenges.

Billy Bragg is many things: a poet, punk rocker, folk musician, and singer-songwriter. He’s also an activist, music historian, and best-selling author. In the words of another poet, he contains multitudes. Bragg’s newest work, The Three Dimensions of Freedom , is a slim volume that makes a weighty argument. It’s a pamphlet in the tradition of Thomas Paine, whose influential polemics helped spark the American Revolution, and later got him convicted of sedition.
