Abstract: A hammock assembly is provided and includes a fastening system, a hammock, a first cover, and a second cover. The fastening system includes a first tape section and second tape section corresponding to the first tape section. The hammock includes a hammock body with the first tape section attached to an edge thereof. The first cover has a cover body with the second tape section attached to an edge thereof, the cover removably attachable to the hammock by connecting the first tape section and the second tape section. The second cover is a permeable netting and includes the second tape section attached to an edge thereof. The second cover convertible with first cover and removably attachable to the hammock by connecting the first tape section and the second tape section.

Abstract: Various implementations include a slide fastener that has a blocking element on one stringer that prevents engagement compatibility with standard elements on the other stringer. For example, at least one blocking element is coupled to a first stringer, and first and second blocking coupling elements are coupled to a second stringer. The contour of the blocking element and the contour of the blocking coupling elements are different from the contour of the standard elements on the stringers such that the standard elements do not engage with the blocking element or the blocking coupling elements in an alternating arrangement. However, the contour of the blocking element and contour of the blocking coupling elements allow for the engagement of the blocking element with the blocking coupling elements in an alternating arrangement.

Abstract: Provided is a slide fastener including: a first fastener stringer that includes a first element row and a first fastener tape, the first element row including a plurality of first elements and one or more second elements; a second fastener stringer that includes a second element row and a second fastener tape, the second element row including one or more second elements; and a slider that is slidable along the first and second element rows. Each of the first element and the second element includes a head coupled to a base via a neck. The base includes an opposite surface that is located at the opposite side of the head. The opposite surface of the second element is positioned farther from the opposed side edge than the opposite surface of the first element. At least two engaged second elements of the first and second element rows constitute a lock unit that is for locking the slider.

Abstract: A readily burstable slide fastener for an inflatable device, such as a lifejacket, includes a first stringer, a second stringer and a slider slidably mounted on the second stringer. At a weakened region along the slide fastener coupling elements are omitted from each of the stringers so that when a bursting force is applied to this region the coupling elements adjacent thereto are disengaged. Coupling elements are omitted from the top of the first stringer so that when the slider is at the top of the coupling elements of the second stringer, the first stringer can disengage from the slider. When the slide fastener is fitted to an inflatable lifejacket, the stringers are separated completely when the lifejacket is inflated.

Abstract: The invention provides a kind of prepolymer with 4-(N-maleimide phenyl)Ether (MPGE) epoxy resin and 4,4?-diphenylmethane bismaleimide (BMI) as reactants, with free radical initiator leading to reaction in solvents, and adding inhibitor after reaction, with the mole ratio of 0.05-0.5 for BMI and MPGE; the initiator usage is 0.01%-0.15% of mole total for reactant monomers; the solvent usage is 50%-70% of the total weight of the reactants; the inhibitor usage is half to double of mole amount of the initiator used. This kind of prepolymer can be used to produce high-performance thermosetting resin composition corresponding to the packaging requirements for electronic components and Integrated Circuits (IC).

Abstract: The present invention provides a slide fastener in which a broken part of a coupling element is not separated easily at the time of a forced cleavage when an airbag is expanded and having an excellent appearance. In the slide fastener (110) in which coupling elements (12, 113) each having a first leg portion and a second leg portion (72; 73) which are forked and extended from a coupling head (70) are sewed to a fastener tape (16, 17) thereof, a V-shaped cutout portion is formed at a single position in the range from a sewing line (84) on a first sewing portion (74) of the first leg portion (72) up to a sewing line (85) on a second sewing portion (75) via a coupling head (70) so as to form a vulnerable portion (80) whose breaking resistance is weakened. Consequently, even if an excessive lateral pulling force is applied to the slide fastener (110), so that the coupling element (12) is broken at the vulnerable portion (80), a broken part of the coupling element (12) is held on the fastener tape (16, 17).
