A cutting device comprises a support to hold a roll of rolled media, a surface upon which the media is unrolled, and first and second cutting guides, each oriented substantially perpendicular to the media's unrolling path and supporting first and second cutters. The first cutter is movably supported by the first cutting guide and is capable of cutting the rolled media substantially parallel to the unrolling path. The second cutter is movably supported by the second cutting guide and is capable of cutting the rolled media substantially perpendicular to the unrolling path. The cutting device further includes a computing system to calculate the amount of rolled media to be dispensed and how best to cut the rolled media.

A golf ball-grabbing device including a cap affixable at the longitudinal extremity of the grip of a putter shaft and having a single central opening therethrough with finger-receiving guide notches therearound, and a movable grabber assembly having (a) a base member shaped to be movably retained within the shaft below the cap and (b) at least three non-destructibly resiliently-deformable resiliently-deformable strip-like fingers each having a proximal end secured to the base member, an arcuate ball-grabbing portion, and a distal end terminating in a camming member having a substantially-planar ball-engagable face, each finger slidably engaged within one of the notches. The movable grabber assembly is slidable with respect to the cap between a non-use position in which the arcuate portions of the fingers are contained only by the shaft and a use position in which the arcuate portions of the fingers are deployed outside the shaft and above the cap.

The invention relates to the technical field of bridge construction, in particular to a cutting device for an expansion joint of a bridge. The cutting device for the expansion joint of the bridge comprises a base and a machine frame. A first sliding rail and a second sliding rail are correspondingly arranged on the inner wall of the front half part of the machine frame, the first sliding rail andthe second sliding rail are correspondingly provided with a first sliding block and a second sliding block, a motor is installed on the first sliding block, a first rotating shaft is arranged on the motor, and a circular parting tool and a first belt pulley are arranged on the first rotating shaft in a sleeving mode. Bearing seats are arranged on the inner wall of the rear half part of the machineframe, a second rotating shaft is connected between the bearing seats, and a cleaning cylinder and a second belt pulley are arranged on the second rotating shaft in a sleeving mode. A vacuum cleaneris arranged on the upper side of the machine frame. The cleaning cylinder cleans up dust on a bridge deck to-be-cut, so that the circular parting tool can cut accurately, and the quality of cutting ofthe expansion joint is guaranteed; the dust produced by the cutting can be recovered in the vacuum cleaner, so that the pollution degree to the environment is effectively reduced; and the cutting depth of the circular parting tool can be quickly adjusted by an extensible rod and the sliding blocks.

The invention provides an ultrasonic cutting mechanism for ear hooks and nose wires for a full-servo mask, which belongs to the field of mask processing and includes an ultrasonic cutting mechanism. The bottom of the ultrasonic cutting mechanism is fixedly supported by a cutter supporting mechanism. The transportation mechanism is fixedly installed at each corner, and the traction mechanism is fixedly installed in the middle of the bottom end of the ultrasonic cutting mechanism. The present invention uses the ultrasonic cutting mechanism, body, ultrasonic generator and ultrasonic horn to facilitate High-intensity ultrasonic cutting energy is generated at the place, and the energy is converted into high-frequency ultrasonic vibration by the transducer, so as to be transmitted to the ultrasonic horn, and then transmitted to the ultrasonic cutter by the ultrasonic horn. The high-frequency vibration generated by the ultrasonic cutter can achieve the purpose of ultrasonic cutting when the ear hooks and nose wires to be cut touch.
