Cutting method of a layer(S) of ceramic powder material having a modulus of rupture that is smaller than about 10 N/mm.sup.2, comprising: a step of moving the layer(S) of ceramic powder material along a given path (P) in a moving direction (A) through a cutting station; and a cutting step, during which at least a first water-jet cutting device cuts said layer(S) of ceramic powder material along a first direction (D1) that is transverse to the moving direction (A), so as to cut said layer(S) of ceramic powder material and obtain a plurality of articles of ceramic powder material (MCP).

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.

Systems and methods treat sucker rods in a machine through a multi-step process. Initially, sucker rods are cleaned before being conditioned. The conditioning process involves using a defined type and a defined size of media, applied at a first intensity to the rods using first media accelerators (first wheels with a specific diameter and rotational speed, and/or imparting a certain amount of media). The conditioned surfaces are then shot peened at a higher intensity using second media accelerators, which can have larger diameters, faster rotational speeds, and/or can impart a greater amount of media. Both the conditioning and shot peening processes involve reclaiming the media for reuse.

An apparatus for treating a surface of an object is disclosed, including a carrier configured to transport the object through a treatment zone and an array of nozzle devices, each nozzle device positioned to deliver a cavitating jet into the treatment zone. The apparatus further includes a fluid source, a pump connected to the fluid source, and a hose configured to carry fluid under high pressure generated by the pump from the fluid source to the array of nozzle devices.
