The present invention relates to a method of producing gelatine, the method comprising the steps of: providing animal material containing collagen; cutting the animal material with at least one fluid cutting jet to form animal material sections; hydrolysing the collagen in the animal material sections to form gelatine; and isolating the gelatine. The invention also relates to a fluid jet cutting device and to the use of a fluid jet cutting device in the production of gelatine. The invention is particularly useful in the production of gelatine from pig skin and/or cow hides and/or fish skin.

The invention relates to a method comprising the steps of: Abrasion, preferably but non-limited by means of sandblasting which produces mechanical roughing on the surface of the glass substrate, optionally applying a primer on the roughed surface, and applying an ink on this primer by means of screen printing which may be digital inkjet screen printing, drying the injected ink deposited by means of digital screen printing, and performing a tempering process. A glass substrate with an embossed surface finish is achieved which simulates the aesthetic and surface texture of different construction materials, such as stone, wood, granite, marble or porcelain, among others.

A water-abrasive suspension cutting facility with at least one high-pressure source (2) which provides a carrier fluid at a high pressure, with at least one exit nozzle (6), with a high-pressure conduit (4) connecting the high-pressure source (2) to the exit nozzle (6), as well as with an abrasive agent feed lock (16). The abrasive agent feed lock (16) is connected to the high-pressure conduit (4) and includes an entry side shut-off element (26) and an exit-side shut-off element (24). A lock chamber (18) is arranged between the entry side shut-off element (26) and an exit-side shut-off element (24). A suction device (30) is configured for producing a reduced pressure in the lock chamber (18) and is connected to the lock chamber (18).

A nozzle assembly for generating fluid jets, such as self-spinning fluid jets. A nozzle body includes a cylindrical nozzle cavity, an inlet, an outlet, and a tubular nozzle rotor assembly positioned with respect to the nozzle cavity. The nozzle rotor assembly can have a ball end and a tubular end and a central fluid passage routed through the nozzle rotor assembly. A fluid swirl enhancer forms communication with the inlet. A replaceable nozzle seat forms communication with the ball end of the nozzle rotor assembly and with the outlet. The ball end of the nozzle rotor assembly pivots, oscillates and rotates against the nozzle seat when pressurized fluid flows through the nozzle assembly.

An integrated liquidjet system capable of stripping, prepping and coating a part includes a cell defining an enclosure, a jig for holding the part inside the cell, an ultrasonic nozzle having an ultrasonic transducer for generating a pulsed liquidjet, a coating particle source for supplying coating particles to the nozzle, a pressurized liquid source for supplying the nozzle with a pressurized liquid to enable the nozzle to generate the pulsed liquidjet to sequentially strip, prep and coat the part, a high-voltage electrode and a ground electrode inside the nozzle for charging the coating particles, and a human-machine interface external to the cell for receiving user commands and for controlling the pulsed liquidjet exiting from the nozzle in response to the user commands.

A high-pressure water jet sheet strip sand-blasting descaling cleaning device, a cleaning line and a system are disclosed. The cleaning device includes a cleaning box (7), a washing box (18) and descaling nozzles (6), the descaling nozzles (6) face to the same width direction of a sheet strip (5) and are arranged in a gradient along a conveying direction of the cleaning box (7) to jet covering the sheet strip (5). The system includes the cleaning device, an abrasive collecting box, a high-pressure water supply system, an abrasive supply-recovery-separation system and a sewage recycling treatment system. The nozzles are slantwise arranged in a gradient along the conveying direction, and the neighboring nozzles do not interfere with each other, and are used for cleaning successively, so that a cleaning process is stable and controllable. A high-pressure water jet sand-blasting cleaning technology is combined with a sheet strip conveying system, different specifications of sheet strips can be continuously and stably conveyed while surfaces thereof are cleaned by using the high-pressure water jet sand-blasting acid-free cleaning technology.
