The invention relates to a device for the erosive processing and/or the cleaning of a material or of a material surface by means of at least one high-pressure fluid jet, comprising a nozzle (1) for outputting a high-pressure fluid jet and an apparatus (2) arranged upstream of the nozzle (1) for producing a pulsed high-pressure fluid jet, wherein the apparatus (2) comprises at least one valve (3). According to the invention, the valve (3) is designed as a servo valve and has an axially movable valve piston (4) for connecting a valve feed (5) to a valve outlet (6) such that the flow through the valve (3) can be specified by means of the axial position of the valve piston (4). The invention further relates to a method for operating a device according to the invention.

The invention features methods and apparatuses for altering a cutting operation during operation of the pressurized liquid jet cutting system. A pressurized liquid jet cutting system includes a pressurized fluid jet cutting head having a plurality of components. The cutting head further includes a sensor configured to sense an operating condition. The sensor transmits a value of the operating condition to a computing device, which alters a subsequent cutting operation. Further, the fluid jet cutting head is configured to work with a data storage mechanism and a reader, such that the data storage mechanism in contact with a body of the fluid jet cutting head is configured to communicate information to a reader of the pressurized liquid jet cutting system. The information is usable to determine a condition of replacement (e.g., a remaining usable life) of the replaceable component, change an operating pressure, change a cutting speed, or alter another operating parameter of the pressurized liquid jet cutting system.

A high pressure pump including a linear actuator having a servo motor to axially rotate a hollow rotor shaft in alternating directions, the servo motor having a stator positioned co-axially around the hollow rotor shaft with an interior of the rotor shaft being co-axially coupled to a drive member to convert axial rotation into reciprocal displacement, the drive member being constrained against linear movement and supporting a shaft. At least one piston is coupled to the shaft and the piston is arranged within a cylinder to define a pumping chamber, whereby alternating rotation of the rotor shaft causes reciprocal linear displacement of the piston to pressurize fluid in the pumping chamber. A drive mechanism includes a controller coupled to a servomotor and an encoder to measure movement of the hollow rotor or output shaft and send a feedback signal proportional to the movement to the controller.

A field-pole magnet manufacturing apparatus manufactures magnet pieces that constitute a field-pole magnet arranged in a rotary electric machine by fracturing the magnet. This manufacturing apparatus includes: a support unit on which the magnet is placed; a fracture unit that is arranged opposite to the support unit across the magnet and is configured to fracture the magnet by pressing the magnet while in contact with the magnet; and a powder removal unit that is configured to remove crush powder produced by fracture of the magnet.

The invention relates to a tool for crushing coke in drums with of high-pressure water jets, which has a housing 2 with a feed system 4 for high-pressure water, and a housing wall 3 with outwardly directed boring and cutting nozzles 5a, 5b, out of the openings 7 of which high-pressure water jets 28 exit, as well as flow channels 4g, 4h, which connect the feed system 4 with the boring and cutting nozzles 5a, 5b. So that the opening of the boring and cutting nozzles is permanently protected and kept free of deposits of coke or the like, the opening of the boring or cutting nozzle is respectively closable by a one- or multi-part flap, which is adjustable between a closed position and an open position.

An apparatus including: a conveyor having a machine direction and a cross-machine direction and a pair of edges spaced apart from one another in the cross-machine direction; a roller mounted to an arm and engaged with a continuous drive, wherein the arm is pivotably mounted to a frame, wherein the roller has a first position and a second position, wherein the roller in the first position is located at a predetermined location above the conveyor and laterally within the pair of edges, wherein the roller in the second position is remote from the predetermined location, and wherein the roller and the continuous drive are separated from one another by an obstruction; a driver operatively engaged with the arm to move the roller from the first position to the second position; and a vacuum port proximal to the roller when the roller is in the first position.

Methods of processing a glass ribbon are provided. The method includes the step of traversing the glass ribbon through a travel path at a predetermined velocity and severing the glass ribbon to create an upstream web and a downstream web. The method further includes the step of increasing a relative velocity of a downstream edge portion with respect to an upstream edge portion to create a gap between an upstream severed edge and a downstream severed edge. In other example methods, a segment of the glass ribbon is removed to create a gap between an upstream severed edge and a downstream severed edge. In still further example methods, an upstream severed edge is directed along a second travel path to create a gap between the upstream severed edge and a downstream severed edge.

A vehicle window glass shear system and method for causing shearing breakage of vehicle window glass under emergency conditions by a concealed and easily operated system, having a concealed handle unit having a handle, a handle-unit bracket, and a handle-unit cable brace, having a concealed shear unit mounted on the bottom edge of the vehicle window with a shear-unit bracket, window-clamping plate, and fasteners, a shear bolt with a piercing point, a shear drive wheel, and a shear-unit cable brace, and having a cable within a cable sleeve transferring the activation force from the handle unit to the shear unit, driving the shear bolt toward the vehicle window and driving the piercing point into the vehicle window causing shearing breakage of the window glass.

An information processing method for generating slice data in a shaping apparatus configured to manufacture a three-dimensional object including a shaping object by sequentially stacking shaping materials based on the slice data generated for each layer, the information processing method including the steps of: acquiring cross-sectional data; judging the presence/absence of a support required region; determining a type of the support to be disposed in the support required region; and generating, as the slice data of a target layer, image data including a structure region indicating the cross-section of the shaping object in the target layer and a support region indicating the cross-section of the support.

A power tool, for example, a portable circular saw, includes a fan, a motor configured to rotate the fan, an output part or shaft driven by the motor, a motor housing that houses the motor, a grip housing connected to the motor housing, a trigger associated with the grip housing, and a brake member configured to brake a rotation of the motor, the brake member being mounted inside the grip housing. The brake member may be a resistive element of a rheostatic braking system. The housing and fan are configured such that cooling air is directed to cool the brake member.
