10598465 · 2020-03-24 · ·

The present invention relates to polyethylene material that has a plurality of unidirectionally oriented polyethylene monolayers cross-plied and compressed at an angle to one another, each polyethylene monolayer composed of ultra high molecular weight polyethylene and essentially devoid of resins. The present invention further relates to ballistic resistant articles that include or incorporate the inventive polyethylene material and to methods of preparing the material and articles incorporating same.

SWELLABLE ADHESIVE NEEDLES

This disclosure relates to swellable needles that include a proximal end portion and a swellable distal end portion. Upon exposure to a liquid, the needles are configured to undergo a shape change from a first configuration in which the width of the needle is tapered from the proximal end portion to the distal end portion to a second configuration in which the distal end portion is more swollen than the proximal end portion. The swellable needles can be double layer swellable needles or single material swellable needles.

Silicone Free Drug Delivery Devices
20200061298 · 2020-02-27 ·

A pre-filled syringe having containing therein at least one therapeutic is provided. The syringe contains a silicone free barrel and an elastomeric syringe stopper that is covered with an expanded polytetrafluoroethylene barrier layer. The presence of a barrier layer that is at least partially porous on the outside of the syringe stopper improves the seal between the stopper and syringe barrel and minimizes the sliding force. In some embodiments, the barrel is formed of a glass material such as a borosilicate glass, that is free of silicone or other lubricants.

Method for Producing a Sealing Tape Roll
20200047474 · 2020-02-13 · ·

A method for producing a sealing tape with interior barrier layers, each of which extends between opposite end surfaces of the sealing tape, the method includes the steps of providing a first foam web; applying a first barrier layer to a first surface of the first foam web to form a laminated foam web; introducing a plurality of first cuts into the top surface and a plurality of second cuts into a bottom surface of the laminated foam web in the transverse direction, the cuts being offset from each other in the longitudinal direction, to form strips arranged behind each other in a row; folding over the strips to produce a foam-barrier layer web, such that subsections of the top surface lie opposite each other and subsections of the bottom surface lie opposite each other; and forming a sealing tape roll from the foam-barrier layer web.

Composite cushioning material and jigless method for making the same
11890843 · 2024-02-06 · ·

The present application discloses a method for fabricating a composite structure for use as a resilient cushion, including: (a) placing a sheet of first resilient material on a surface; (b) cutting the sheet of first resilient material by pressing a cutter on to the first resilient material to produce a cut sheet of first resilient material displaying a cutting pattern of discrete first resilient elements of defined widths and lengths, wherein at least one of the first resilient elements touches adjacent resilient elements along its side; and (c) mounting a first expanse of material on at least one of the first resilient elements of the cut sheet of first resilient material to form a first composite structure.
