A tool is provided for driving fasteners that includes a torque limiting mechanism therein. The torque limiting mechanism includes a first frictional engagement member disposed on the drive shaft for the tool that is engaged by one or more second frictional engagement members disposed on one or more sides of the first frictional member. The second frictional engagement members are biased into engagement with the first member by biasing members disposed within the handle that can be adjusted in order to provide more or less of a biasing force to control the frictional engagement of the second member with the first member and thereby control the torque limiting function of the torque limiting mechanism. In addition, a drive shaft is also engaged with a ratcheting mechanism that enables the tool to drive a fastener into a suitable substrate in only a single direction.

A brake shoe is used on a railway vehicle for both applying a braking force and simultaneously reconditioning a wheel tread surface of a wheel disposed on such railway vehicle during a normal braking application on such vehicle. The brake shoe comprises a backing plate having a predetermined configuration and a first friction type material formed into a brake shoe and having a predetermined shape. There is a brake surface for engaging a wheel tread having a predetermined configuration and having a predetermined surface area. A second friction type material is formed as a discrete insert, having a predetermined shape and a predetermined width, and molded into first friction type material. One surface of the discrete insert being disposed coincidently as part of the brake surface of the brake shoe. The second friction type material exhibits greater abrasive properties than does the first friction type material.

The pole shoe is made of permeability materials, when the magnetic control target works, a direct current or radio-frequency power supply is applied to the pole shoe, the water inlet nozzle and the water outlet nozzle are welded by argon arc welding under the pole shoe, cooling water enters from a low place and outflows from a high place, and hermetical seal is realized by the hermetical rubber ring. The materials of the insulating seat are temperature-resistant insulating materials which can be used in vacuum, and are installed between the permanent seat (anode) and the pole shoe (cathode), and an insulating cap has the insulating action between an electriferous screw (cathode) and the permanent seat (anode). The invention has simple structure and low cost.

The invention is applied in the field of liquid crystal display, and provides a three-dimensional (3D) image display control method and a 3D image display control system. The method comprises the following steps of: receiving a 3D image signal from a 3D image signal source, and pre-processing the 3D image signal to obtain a first frame sequence; performing frame processing on the first frame sequence to obtain a second frame sequence consisting of a gray frame GL, a left-eye image L'', the gray frame GR and a right-eye image R'' which are continuous, wherein the frame processing comprises frequency multiplication, black frame interpolation and gray frame interpolation; and transmitting the second frame sequence to a liquid crystal screen for display, simultaneously generating a shutter glasses control signal and a backlight switching control signal according to a synchronizing signal of the second frame sequence, controlling the switching state of shutter glasses by using the shutter glasses control signal, and controlling the switching state of a backlight source of the liquid crystal display screen by using the backlight switching control signal. The embodiment of the invention fulfills the aim of definitely displaying a 3D image by performing the pre-processing and the frame processing on the 3D image.

The invention relates to a robot global space positioning method based on graphical labels and a camera.The method comprises the steps that the graphical labels are laid every a certain distance in the working space of a robot; a processor sets the movement path of the robot so that the robot can observe the graphical labels through the camera on the movement path; when the robot can not observe the graphical labels, the space position of the robot is calculated according to the advancing mileage of the robot; when the robot shoots the graphical labels through the camera, the angles of the robot relative to the graphical labels and the position of the robot are worked out, and the global positioning information of the robot is acquired through the space position of the graphical labels.The ground labels can be recognized through the camera, and therefore the space positions of the robot or other devices can be corrected, contact with the robot does not exist, maintaining is easy, the recognition speed is high, installation is easy, and rearrangement can be conducted many times.

An improved head for a flexible line trimmer apparatus is provided. The improved head includes a metal tubing that extends through the head and surrounds a cutting line of selected length. The tubing is provided with a flared exit portal increasing the efficiency of the head. The contact surface eliminates the possibility of the cutting line fusing to plastic surfaces due to heating caused by friction. The head is surrounded with an interior perimeter counterweight to store kinetic energy on each end having a parabolic surface of revolution concentric with the axis of the tubing. A replaceable cartridge is provided to increase the ease of maintenance and the useful life of the head.
