摘要:
The outer profile of the spring is shaped to control breakover (i.e., the change in spring deflection from constant to rising rate) and spring rate. A process for inducing breakover in thick-walled elastomeric springs which normally have no breakover, and for controlling breakover, whether so induced or occurring naturally, as well as spring rate, is disclosed.

Vibration and shock isolation, as well as working fluid flow path sealing in a turbine-type power plant having a turbine housing 18 with a radially directed peripheral outlet 38 is achieved by locating the turbine housing 18 within a tubular housing 44 with a radially inwardly opening port 46 aligned with the turbine housing outlet 38 and disposing elastomeric seal and turbine mounts 50, 52 mounted on spaced side walls 28 and 30 for sealing the outlet 38 to the port 46 and to serve as engine mounts for a turbine wheel 10 and the turbine housing 18.

A resilient bumper assembly for use on such as for example on a ladder carrier or encapsulated cushion for cylinder shaped objects features a base member with an elongated trough formed therein and outriggers disposed at opposite ends of the trough. Each of the outriggers includes a horizontal arm, projecting toward the other outrigger. A hollow tubular resilient member which may be a length of a hose is inserted between the outriggers and held within the trough so that the arms project into opposite ends of the resilient member and retain it against transverse and lateral movement.The assembly is simple, convenient and economical to manufacture and use and can be adapted for use in a variety of applications requiring a bumper arrangement.

An elastically deformable fender comprising an impact receiving section having a predetermined thickness and a top surface being formed flat and forming a contact surface with a broadside, a pair of supporting sections extending from the reverse side of the impact receiving section mentioned above so as to diverge away from each other in an unfolded fan fashion and formed integrally with the impact receiving section, and fitting sections expanding outwardly from the ends of the supporting sections in parallel to the contact surface aforementioned. The thickness of the impact receiving section mentioned above is formed thick so as to protrude distinctly from the supporting sections and the width is formed smaller than the span between the heels of the supporting sections. Furthermore, between the supporting sections on the reverse side of the impact receiving section a hollow portion is formed lengthwise for preventing the impact receiving section from curving when the contact load of a ship is applied.

The present application is concerned with an extrusion process for an elongated stiff but bendable plastic article which finds particular utility in highway delineators. The article has a central lens shape in the cross-section perpendicular to its major axis which is formed by joining two sheets along both of their longitudinal edges. The sheets both have parallel longitudinal edges and are configured in an arc in their shorter dimension. A reverse radius is provided in each longitudinal edge just before it joins the similar edge of the other sheet to allow the article to be bent 90.degree. across its major axis in the plane of its minor axis without significant plastic deformation. The article is constructed by pressing the cooled edges of thermoplastic sheets that can sustain substantial elastic deformation.

A spring (10) includes a tube (12) having an elliptical cross section, with the greater axial dimension (22) extending laterally and the lesser axial dimension (24) extending vertically. A plurality of cuts (20) in the form of slots passing through most of a wall of the tube (12) extend perpendicularly to a longitudinal axis (16) extending along the tube (12). An uncut portion (26) of the tube wall extends along the tube (12) for bonding or fastening the tube to a suitable base, such as a bottom (28) of a seat cushion (30).

A fender (10) which is essentially U-shaped in cross section and which consists of elastomer material in its energy-absorbing part, is manufactured in planar configuration and folded to U-sectional shape on mounting. To make folding possible and to provide both an equalisation of tensile stresses and an increase of the transfer of forces between the web (12) and the legs (13) of the U-shaped cross section, longitudinal slots (17) are formed on the inside of the U-shaped cross section at the transition between the web and the legs. The mouth edges of the slot are bevelled and form mutually abutting supporting surfaces (18) for said transfer of forces. At the bottom of the slot (19), a longitudinal open channel (21) has been left to equalize the tensile stress occurring in the fender material on folding.
摘要:
A connecting device has at least one bolt and a loop of unidirectional fis bound by or embedded in a synthetic matrix material looping around the bolt to form a looping range extending around the bolt. The resistance of the matrix material in the looping range against squeeze-out is improved by reinforcing fiber layers located in the looping range of the loop around the bolt. The fibers of these reinforcing layers are also bound by the matrix of the synthetic material. The reinforcing fibers form insert and/or cover layers having at least one main fiber orientation which extends at least approximately in the direction of the longitudinal bolt axis whereas the unidirectional fibers forming the loop extend approximately tangentially to the bolt in the looping range.

A traffic delineator includes a post having a collapsible, box-like cross-section and a base for mounting the post upright and securing it to a road surface. Inwardly disposed sidewalls of the post collapse inwardly at a bend area when the post is hit by a vehicle, permitting the post to collapse and bend through 90.degree. or more, yet the post self-restores itself to an elongated, unbent position when the vehicle moves away. A base includes receptacle surfaces and pins for engaging and securing the post therein, together with a lower surface configuration enhancing the adhesive attachment of the base to a surface.

A marine fender is disclosed, which comprises a hollow cylindrical body composed of rubber or rubbery elastic material, each end of which being provided with a flange for a quay wall or a shock receiving member, an annular rigid reinforcing plate embedded in each flange, and a fillet reinforcement provided on a foot portion of each flange. In the marine fender, an annular groove is further formed in a region adjacent to the fillet reinforcement at each end of the body.
