An operator controlled wire rope maintenance apparatus for remotely discerning and locating wire rope wear problems.

A binding material for binding a bale (14) of crop material has bale (14) identification tags (62) used to identify properties of the bale (14) that is bound by the binding material. The binding material (52) includes at least one strand of a non-identifying filament and one strand of an identifying filament incorporating the identification tag (62). The non-identifying filament and the identifying filament are wound together before the binding material (52) is used to bind the bale. The identifying filament has an RFID inlay having conducting wires of an antenna connected to an RFID chip, with the length of the inlay between 10 and 24 cm. The RFID inlay comprises a segment of the identifying filament with adjacent RFID inlays spaced along the identifying filament at a desired interval. The identifying strand incorporating the RFID inlay is wound during a binding material production process with the at least one non-identifying filament into a single twine strand.

The present invention provides an apparatus for measurement of a limb circumference, comprising a pull string module, a first measurement module and a second measurement module. The pull string module comprises a surrounding component, wherein the surrounding component comprises an encircling part disposed around a limb of an individual; the first measurement module is disposed at the pull string module and moves alone the longitudinal axis of the limb and meanwhile measures the length of the limb; and the second measurement module measures the length of the encircling part simultaneously when the first measurement module move alone the limb, so as to determine the correlation between the limb length and the limb circumference. The present invention further provides a device including two or more apparatuses of the present invention to measure the limb compliance and to be used in the treatment of lymphedema.

A sample gauge length and length after fracture measuring device includes a worktable, a first sliding table support and a second sliding table support, a control and length display, a spiral micrometer head, a scriber, a sample, etc. The reading device using the spiral micrometer head to directly measure the gauge length and the length after fracture has a detection accuracy of 0.01 mm, which is superior to the requirement of 0.05 mm in GB/T228 Metallic Materials Tensile Testing at Ambient Temperature.

An apparatus for measuring a plate-shaped workpiece comprises a conveying device for conveying the plate-shaped workpiece in a conveying direction along a conveying path and first and second measuring devices including respective first and second drivers and respective first and second measuring rulers. Each of the first and second drivers is selectively couplable to and decouplable from a main surface of the plate-shaped workpiece. In a coupled state, the drivers are moveable together with the plate-shaped workpiece in the conveying direction and, in a decoupled state, are actively movable in a direction opposite to the conveying direction. The measuring rulers extend in the conveying direction such that the positions and/or movement distances of the drivers in the conveying direction are detectable. The first and second measuring rulers detect different regions of the conveying path of the plate-shaped workpiece in the conveying direction.

Provided is a measuring device capable of flexibly identifying a different tool detection position for each user, for example. This measuring device for measuring a distance from a reference position in a machine tool to a tool detection position of a measuring instrument, for said measuring instrument for measuring the length of a cutting tool mounted in the machine tool, comprises: a speed acquiring unit for acquiring a predetermined feeding speed at which the cutting tool is moved toward the measuring instrument when the length of the cutting tool is being measured; a movement control unit for causing a pressed surface of the measuring instrument to be pressed by a reference tool which has a known length and which is mounted in the machine tool, by moving a tip end of the reference tool toward the measuring instrument at the feeding speed acquired by the speed acquiring unit; a detecting unit for detecting a signal indicating the tool detection position, output as a result of the pressing of the measuring instrument; and an identifying unit for identifying the tool detection position of the measuring instrument on the basis of the position of the tip end of the reference tool at the timing at which the signal was detected.

A feed sensor detects location of a wood log to be moved with a feed mechanism in relation to a predetermined point in a device. A control circuit controls a feed mechanism to feed the log for a preset length on the basis of the location of the log detected by the feed sensor. The control circuit controls the cutting mechanism to cut a wood block from a log longer than the predetermined length when the feed mechanism has fed the log for the preset length and a splitting mechanism to split the wood block cut from the log.

A dustproof counter device of a measuring wheel has a base, a counter, and a pedal setting component. The base has a component opening formed through a top of the base and a dustproof flange protruding from the base and surrounding the component opening. The counter is disposed in the base and has a zeroing button extending into the component opening of the base. The pedal setting component has a dustproof cap covering and surrounding the dustproof flange of the base, and abutting against the zeroing button. When the pedal setting component is pressed by a user's foot, dust is kept from dropping into the base by the dustproof cap.

A bale identification assembly has a binding material with identification tags at spaced intervals is used by a knotter system to bind a formed bale. A read module with an antenna transmits interrogator signals and also receives authentication replies from identification tags. The bale identification assembly has a bale drop sensor with a paddle. As a completed bale passes through the discharge chute, the completed bale interacts with the paddle causing the bale drop sensor to activate. Activation of the bale drop sensor activates the antenna for a specified active cycle, and during its active cycle, the read module assigns any identification tag that is sensed to the completed bale that is leaving the discharge chute. A controller receives information from at least one crop sensor and/or bale sensor and associates the information about the completed bale with the identification tag on the completed bale.
