A weight device with handle comprises a body (3) of approximately spheroidal and hollow shape containing a ballast (5) and comprises a handle (7) having an approximately C shape and with ends (9) incorporated in the wall (11) of the body (3) or in respective protrusions (13) of said wall (11). The wall (11) of the body (3) comprises an outer layer (15) and an inner layer (17) which are mutually adherent and extending in almost every portion of the body (3). The outer layer (15) is made of soft and/or shockproof material of the closed-cell or open-cell foam type or of the elastomeric type with impact energy absorption. The inner layer (17) is made of rigid or semi-rigid material and of a type that ensures the stability of the shape of the body (3) over time, of cross-linked thermoplastic resin or other stable material with a high elastic modulus.

A multilayer article is provided which is suitable for use in making (or as) a fuel container by rotational molding, wherein the multilayer article has at least one layer of a thermally cured polymer composition and another layer of a barrier polymer composition, wherein the barrier polymer composition comprises a specified modified ethylene-vinyl alcohol copolymer as a barrier polymer.

A large animal feed dispensing container and method of manufacturing the container and method of using the device for delivering a controlled amount of feed to large animals in an outdoor. The housing unit and transecting plate may be molded as a single fused piece. The housing unit includes small openings intended for dispensation in the first chamber that contains feed. The housing unit contains a container for ballast material keep the feed-dispensing container to stabilize the feed-dispensing container in one location.

The technical solution relates to the field of processing polymers and can be used in various branches of the national economy for manufacturing hollow articles of the bodies-of-revolution type (tubes), and in particular for manufacturing semifinished biodegradable polymeric stents which are usable in medicine for replacing hollow organs, for example blood vessels. The apparatus for manufacturing thin-walled bodies of revolution comprises a heatable expander which is mounted rotatably about a longitudinal axis, and a feeder for supplying moldable material, said feeder being mounted above the expander so as to be movable therealong, wherein the lower part of the feeder is heatable, the expander is hollow with a reflective internal surface, and the heater of the expander is in the form of a laser, the radiation of which is transported into the expander. The use of the apparatus will make it possible to reduce the thermal action on a polymer when producing semi-finished articles with defined geometrical dimensions from polymeric materials.

A method and systems for controlling optical transmissivity of a polish pad material are provided. The method and systems may include adjusting control parameters to determine the optical transmissivity of a polish pad material. The control parameters may also include pre-processing controls, casting controls, and/or curing controls. Methods and systems also provided for assembling a polish pad that controls the optical transmissivity of the polish pad. Additionally, a polish pad with a controlled optical transmissivity is provided.

A method of producing fibers, includes placing a composition that includes one or more fluoropolymers in the body of a fiber producing device and rotating the device at a speed sufficient to eject material from the fiber producing device to form fluoropolymer microfibers and/or nanofibers.

The present disclosure relates to a hand rail. The hand rail comprises an elongate handle and an attachment portion, the handle being connected to the attachment portion by a continuous connecting web that extends from a first end of the hand rail to a second end of the hand rail to define an elongate channel between the handle and the attachment portion, the channel being open at the first end of the handle and closed at the second end of the handle; wherein a base of the channel is sloped relative to the handle such that liquid drains out of the channel when the handle is in a horizontal orientation.

The current inventive technology described methods and apparatus for the production of a helium-free balloon having customizable reflective features.

A containment system includes a rotationally molded polymeric base unit in the form of a tub having an open top. The base unit includes a generally L-shaped rim at the open top comprised of an upwardly extending section that terminates in a cut edge and an inwardly extending section. The containment system also includes at least one perforated grate having a top side, a bottom side and a peripheral edge. The at least one perforated grate is supported, at least in part, by the inwardly extending section of the rim in such a manner that a container can be supported on the top side of the grate above the tub.
