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.

(Problem) In conventional method for producing artificial graphite, in order to obtain a product having excellent crystallinity, it was necessary to mold a filler and a binder and then repeat impregnation, carbonization and graphitization, and since carbonization and graphitization proceeded by a solid phase reaction, a period of time of as long as 2 to 3 months was required for the production and cost was high and further, a large size structure in the shape of column and cylinder could not be produced. In addition, nanocarbon materials such as carbon nanotube, carbon nanofiber and carbon nanohorn could not be produced. (Means to solve) A properly pre-baked filler is sealed in a graphite vessel and is subsequently subjected to hot isostatic pressing (HIP) treatment, thereby allowing gases such as hydrocarbon and hydrogen to be generated from the filler and precipitating vapor-phase-grown graphite around and inside the filler using the generated gases as a source material, and thereby, an integrated structure of carbide of the filler and the vapor-phase-grown graphite is produced. In addition, nanocarbon materials are produced selectively and efficiently by adding a catalyst or adjusting the HIP treating temperature.

Portioning system 10 includes a scanner 200 for scanning work products 13 being carried on the conveyor 12. A cutter system 17 includes an array or manifold cutter 18 and single cutter 19 for cutting the work products into desired sized end pieces. The cutter assemblies 18 and 19 are carried on respective carriages 16 and 26 to move the cutters as required along predetermined cutting paths as controlled by control system 220.

A method and apparatus for replacement of damages display shield (typically glass) covering a display screen on a device, typically a mobile phone. Mobile phones have an electronic display protected by a glass shield. Between the glass and the display is often a plastic polarizing or other intermediary sheet. Removal of a damage glass can be accomplished by cutting thru the polarizer with a moving wire or blade. This separates the glass from the sensitive display and allows replacement of the glass without damaging the more expensive display.

Waterjet systems including control valves and associated devices, systems, and methods are disclosed. A waterjet system configured in accordance with a particular embodiment includes a fluid source, a jet outlet, and a fluid conveyance extending from the fluid source to the jet outlet. The system further includes a control valve positioned along the fluid conveyance downstream from the fluid source and upstream from the jet outlet. The fluid conveyance has a first portion upstream from the control valve and a second portion downstream from the control valve. The control valve is configured to controllably reduce a pressure of fluid within the second portion of the fluid conveyance relative to a pressure of fluid within the first portion of the fluid conveyance. The first portion of the fluid conveyance is configured to accommodate movement of the jet outlet relative to the fluid source.

An air guide box of a paper production installation has a front broad side and a rear broad side, each having a width b. An extension device is attachable to a broad side of the air box guide and has a width of at least 0.25*b and a length of at least 10 mm. A surface thereof is defined with at least one recess having a maximum clear opening of at least 0.1 mm for the through passage of at least one high-pressure water jet or at least one laser beam.

A waterjet cutting method is provided which includes directing a waterjet onto a surface of a workpiece that is exposed to the surrounding atmosphere, the interaction of the waterjet with the exposed surface defining a cutting location, and simultaneously directing a gas stream onto the exposed surface of the workpiece at or adjacent the cutting location to maintain a cutting environment at the cutting location that is, apart from the waterjet, substantially devoid of fluid or particulate matter. The method may further include moving a source of the waterjet relative to the workpiece to cut the workpiece along a desired path while continuously directing the gas stream onto the exposed surface of the workpiece at or adjacent the cutting location.

Devices and methods for processing animal or human tissue are provided. The devices may include a vacuum surface to secure the tissue in place and an apparatus for removing fat or other material from the tissue. The apparatus can include one or more blades and/or a fluid jet system.
