The invention relates to a system including a cryogenic container, such as an LNG container or a hydrogen container, with a first removal line for removing cryogenic fluid in a gas phase and a second removal line for removing cryogenic fluid in a liquid phase being routed into the cryogenic container. The system includes a single-piece economizer valve block having at least a first and a second inlet port and an outlet port, the two inlet ports and the outlet port being connected inside the single-piece economizer valve block by a connection passage having a connecting portion on the gas phase side, a connecting portion on the liquid phase side and a connecting portion on the end side, the single-piece economizer valve block having at least one valve recess open towards the outside, the valve recess starting at the node, and a valve being inserted into the valve recess.

A compression system includes a compression device and a controller. A treated material is pressed longitudinally through a compression chamber by simultaneously applying a lateral pressure and a two-dimensional cross-section compression which includes a pressure applied in a direction traverse to a direction of transport and a pressure applied in a direction parallel to the direction of transport. The controller controls the two-dimensional cross-section compression applied to the treated material such that, during compression, liquids in the treated material migrate to the outer surface of the treated material upon reaching the outlet orifice.

A flexible tubing material includes a radiation crosslinked blend of a first elastomeric polymer including a styrenic thermoplastic elastomer, an ethylene vinyl acetate elastomer, a polylefin elastomer with a second elastomeric polymer including a polyolefin elastomer, a diene elastomer, or combination thereof, with the proviso that the first elastomeric polymer and the second elastomeric polymer are different. In an embodiment, a method of making a material includes providing the first elastomeric polymer, providing the second elastomeric polymer, blending the first elastomeric polymer and the second elastomeric polymer, extruding or injection molding the blend, and crosslinking the blend with radiation.

Disclosed are plastic products from a recycled plastic mix of unidentified, unclean and unsorted mixed plastic waste made with a system comprising thermal and mechanical processing of the recycled plastic waste using continuous extrusion foaming, two-phase cooling, continuous metering of the pulling strength and automatic adjustment of the pulling speed and extrusion speed.

A slot die assembly for applying at least one material onto a substrate includes an adapter having a passive heat transfer device, a shim package fluidically connected to the adapter, the shim package having a first material discharge slot and a second material discharge slot, and a die plate having a one or more fluid channels fluidically connected to the shim package. The assembly also includes one or more mounting studs extending from the adapter, the mounting studs configured to engage a parent machine.

A method for controlling temperature rise in divided heating zones of a barrel of a molding machine includes: setting tentative target temperatures for the respective heating zones; simultaneously raising temperatures in the heating zones to the set tentative target temperatures; when temperatures in the heating zones reach the respective tentative target temperatures, selecting a master zone from the heating zones, and selecting, as a slave zone, a heating zone which is other than the master zone among the heating zones; and after temperatures in the heating zones reach the respective tentative temperatures, raising the temperatures in the master zone and the slave zone to respective final target temperatures according to an attainment degree of temperature rise in the master zone.

Disclosed is a device and method for dynamic extrusion molding of plastic articles having variable micro-channel. The device mainly includes a single-screw extruder, a dynamic extrusion die, a fluid source, a water sink, a tractor, a winding device, and a data acquisition and control system. Near outlet of extrusion die, when the end portion of a syringe needle is at different positions, the inner diameter of the micro-channel of the extrusion molded plastic article is also different. When the hollow syringe core within the dynamic extrusion die performs a high-frequency short-range vibration along an extrusion direction, the inner diameter of the micro-channel of the extruded plastic articles is dynamically variable. The plastic articles of variable micro-channel of the present invention has novel structure with high dimensional accuracy, and a variety of varying patterns, it can be stably produced by simple processing equipment with high level of automation.

A fuel line comprising a thermoplastic composition is described. The thermoplastic compositions exhibit high strength and flexibility and can be used to form one or more layers of single layer or multi-layer fuel lines. Methods for forming the thermoplastic compositions are also described. Formation methods include dynamic vulcanization of a composition that includes an impact modifier dispersed throughout a polyarylene sulfide. A crosslinking agent is combined with the other components of the composition following dispersal of the impact modifier. The crosslinking agent reacts with the impact modifier to form crosslinks within and among the polymer chains of the impact modifier. The compositions can exhibit excellent physical characteristics at extreme temperatures.
