A dynamic reef is provided in accordance with the invention. The dynamic reef includes anchoring means for anchoring the reef in a substantially fixed position with respect to a shoreline, an elastic rubber tubing secured to the anchoring means, and at least one flotation collar positioned so as to be rotatable about the rubber tubing for the purpose of dissipating wave energy. A solar strobe unit may be positioned on the rubber tubing at the end opposite the anchoring means and functions as a warning device. A method for preventing shoreline erosion and a system for reducing the effects of waves on a shoreline are also provided in accordance with the invention.

An inflator comprising: a pressure vessel (10) for storing a quantity of stored inflation gas under pressure. The pressure vessel comprising a first burst disk (46) and a seal disk (310) both for selectively sealing same. The inflator (10) including a gas release mechanism (52, 300) for permitting the controlled, staged release of the inflation gas at determinable inflation rates. The gas release mechanism includes: a first pyrotechnic device, positioned outside of the pressure vessel and spaced from the first burst disk (46), including a piston (72) moved into a disk piercing position to rupture the first burst disk (46) in response to the buildup of pressure caused burning of a first quantity of propellant material (218). The bursting of the first burst disk permits the inflation gas to initially flow out of the pressure vessel at a determinable cold inflation rate, the piston thereafter provides a conduit to communicate the products of combustion of the burning propellent to the pressure means so as to increase the temperature of the inflation gas therein and thereby increase the rate of egress of the gas. The inflator (10) also includes a second pyrotechnic mechanism (300), positioned outside of the pressure vessel and spaced from the seal disk (310), for providing, when activated, additional products of combustion arising from burning of a second quantity of propellent material, the products of combustion opening the seal disk (310) and thereafter entering the pressure vessel to heat the inflation gas therein and thereby elevate the rate of egress of the inflation gas above the rate achievable by the first pyrotechnic device.
摘要:
An inflator for an air cushion including a pressure vessel comprising a hollow sleeve for storing a quantity of inert gas such as Argon. One end of the sleeve is closed by a first pyrotechnic actuator assembly while the other end of the sleeve may include a closed end or another pyrotechnic actuator assembly. The pressure vessel is secured within a diffuser which directs inflation gases into the air cushion. The pressure vessel in cooperation with the diffuser defines various regions which assist in reducing the gas turbulence and heat transfer between the gas and the diffuser.

A shock-absorbing and motorist warning highway barrier is provided comprising a plurality of elongated upstanding units adapted to be joined in end to end relation, each unit comprising an outwardly flared base and an upstanding central portion having interfitting protrusions at opposed ends thereof facilitating end to end coupling of adjacent units, opposed side surfaces of the upstanding portion having a plurality of transversely aligned and longitudinally spaced recesses to receive resilient cylindrical members in a manner to protrude substantially from such surfaces, the cylindrical members being insertable and removable through the top of the unit and being secured in place by a cover member having downward protrusions interfitting with the aligned recesses in said unit. In preferred adaptations each unit may have a sinusoidal contour in the longitudinal dimension incorporating two sine curves, and/or the recesses and cylindrical members mounted therein may be outwardly inclined about 5.degree. to 10.degree. from the vertical. To facilitate direction change in aligning units to form a highway barrier, connecting units are provided having closely spaced angularly disposed coupling end portions, and providing at one side thereof one recess to receive a single resilient cylindrical member. The main barrier units and connecting units may be molded concrete, but are preferably formed as thin-walled plastic shells to be filled with water, sand or cement at the time of installation. The cylindrical members can be solid resilient members or thin-walled plastic members filled with compressed air, liquid or sand.

A method and apparatus for filling motor vehicle gas bags. The inflating gas flows to a manifold, about which a motor vehicle gas bag or bags are disposed, whereby the filling of gas bag (or bags) is delayed, it being filled first with gas filling a part of the manifold, and then with a greater quantity of gas filling the entire manifold upon the rupture of burst disc means.

A tissue retraction system includes a dilator and a first retractor member and a retraction assembly. The dilator is configured to be inserted into a tissue body and also includes at least one engagement member. The first retractor member includes a body and at least one engagement member that is configured to attach to the at least one engagement member of the dilator so as to removably attach the retractor member to the dilator body. The retraction assembly includes a retractor body and at least a second retractor member that is movably supported by the retractor body. The retractor body is configured to be attached to the first retractor member. The tissue protection system may also include a neuromonitoring member configured to determine a characteristics of the tissue.
摘要:
An assembly comprising:a hollow cylindrical member or can including an opening into which a gas generator may be inserted, the gas generator of the type responsive to a control signal, for generating gas to inflate an air bag. The assembly including the air bag, for protecting, when activated, an occupant of a vehicle, comprising an inflatable bag or sack, disposed in a compacted or stored condition, during periods prior to deployment, proximate a side of the cylindrical member containing at least one aperture, the inflatable bag, including an open end disposed about the cylindrical member to receive the gas and including relatively opposing flaps extending from proximate the open end and adapted to envelop the cylindrical member, the flaps, proximate a side of the cylindrical member, away from the at least one aperture, disposed in an overlapping, condition, one to the other. A band of tearable material is provided to secure the air bag in its stored or predeployment condition.
摘要:
A sectional shock-absorbing and motorist warning highway barrier is provided in the form of multi-component sections about four feet in length, and adapted to be joined together in end-to-end relation to form a continuous barrier, each section being made up of four vertically aligned horizontal components, providing a top component, and two mid-components of uniform thickness, and a flared bottom component, such components having offsets at opposed ends thereof for aligning successive sections with such offsets having transverse apertures for receiving bolts in securing together successive sections, abutting surfaces of the horizontal components having aligned offsets of semi-spherical contour to receive spherical plastic bumper members protrudingly and rotatably supported in the assembled section. The horizontal components are fashioned from concrete, suitably encased in plastic shells, and the spherical plastic bumper members may be either air filled, or filled with water or sand for added weight. The offsets for aligning successive sections are for direct section-to-section engagement, or for reception of vertically oriented, and suitably flexible interfitting connecting members. With either type of section-to-section connections the free ends of a multi-sectional assemblage are provided with appropriately contoured vertical connecting members interfitting with the aligning offsets, preferably including means providing visibility enhancement.
