International Classification:

A47H 1/10

US Classification:

248317, 62 511, 292162

Abstract:

A suspension system for a cryostat includes a coupling mechanism, a fixation body, and a pin. The coupling mechanism is joined to an outer vessel and coupled with a strap. The fixation body is joined to an inner vessel. The fixation body extends between a front side that faces the coupling mechanism and an opposite receiving side with an interior channel extending from the receiving side to the front side. The channel defines a front opening in the front side and a rear opening in the receiving side. The pin is loaded into the fixation body through the rear opening in the receiving side of the fixation body with the strap looped around the pin and extending through the front opening to the coupling mechanism. The pin secures the coupling mechanism to the fixation body via the strap by engaging the fixation body inside the channel.

International Classification:

B32B003/10

US Classification:

428/131000, 428/402000

Abstract:

This invention provides an apparatus and method for injecting an additive directly into a polymer melt stream. The method comprises supplying a melt flow of a polymeric host material to a die assembly having a thin-plate assembly and injecting at least one additive into at least one predetermined location in a cross-section of the melt flow of the polymeric host material while the melt flow passes through the die assembly. The method achieves uniform dosing of the one or more additives in the extrusion direction in the polymeric host material without homogeneously mixing the one or more additives and the polymeric host material. The apparatus for directly injecting one or more additives into a polymer melt stream comprises a pumping system, a die assembly having a thin-plate assembly, and a distribution line.

US Classification:

526/065000, 526/312000

Abstract:

Continuous anionic polymerization and melt-spinning of a polycaprolactam includes forming a reaction mixture by bringing at least two streams of liquid caprolactam respectively containing a polymerization initiator and co-initiator into contact with one another, and then subjecting the reaction mixture to anionic polymerization reaction conditions to obtain a molten polycaprolactam. The molten polycaprolactam is the directly (i.e., without intermediate solidification) transferred to, and extruded through, a fiber-forming orifice of a spinneret to form a fiber thereof. One exemplary system to achieve such continuous anionic polymerization and melt-spinning of polycaprolactam includes a mixer for receiving and mixing at least two streams of liquid caprolactam respectively containing a polymerization initiator and co-initiator, and a reactor and melt-spinning apparatus downstream of the mixer. The reactor and melt-spinning apparatus most preferably is formed of multiple plates which establish a reactor zone having a flow path for the reaction mixture which is sized and configured to achieve a predetermined residence time of the reaction mixture therein, and a temperature control zone in thermal communication with the reactor plate for controlling the temperature of the reaction plate to achieve anionic polymerization reaction conditions while the reaction mixture is flowing along the defined flow path therein to obtain the molten polycaprolactam. A spinneret zone downstream of the reactor zone thus receives the molten polycaprolactam directly and forms a fiber therefrom by extruding it through the spinneret's fiber-spinning orifice.

US Classification:

162129, 493 59

Abstract:

An arcuate die board formed as a multi-layered paperboard structure. The die board is initially produced as a full cylindrical paperboard tube, which is subsequently cut lengthwise to form two or more part-cylindrical portions each of which is used to fabricate a die board. The die board is then cut to form the slots in its outer surface for mounting die tools. The multi-layered paperboard tube can be spirally wound, convolutely wound, or formed by a linear draw process. The part-cylindrical wall is formed predominantly, substantially entirely, or entirely of paperboard plies adhesively laminated together.

International Classification:

US Classification:

523205

Abstract:

Polymeric compositions include a nonaqueous additive system having dispersant-coated pigments physically dispersed in a liquid nonaqueous polymeric carrier which may be added directly to a melt flow of a polymeric host material. The additive system employed in the polymeric systems is most preferably in the form of a particulate paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being spun into filaments. By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of host polymeric material, shaped objects of the polymeric material (e. g. , melt-spun filaments) having different additive attributes may be produced on a continuous basis without shutting down the shaping operation.
