A back pad for use in connection with a safety harness including at least two spaced back straps. The back pad includes a shield covering at least a portion of each of the back straps of the safety harness. The shield extends between the back straps to cover a portion of a user's back when the safety harness is worn. A full body safety harness to be worn by a person includes an upper torso portion and a lower seat portion. The upper torso portion is operatively connected to the lower seat portion by a first connector on a first lateral side and a second connector on a second lateral side thereof. The first connector and the second connector can, for example, enable forward and rearward rotation of the upper torso portion relative to the lower seat portion (for example, without causing a significant increase in tension in the upper torso portion or the lower seat portion). At least one of the first connector and the second connector includes a shaft. The upper torso portion includes at least one connecting member having a passage formed therein. The lower seat portion includes at least one connecting member have a passage formed therein. The shaft passes through the passage of the at least one connecting member of the upper torso portion and through the passage of the at least one connecting member of the lower torso portion.

A full body safety harness to be worn by a person includes an upper torso portion and a lower seat portion. The upper torso portion is operatively connected to the lower seat portion by a first connector on a first lateral side and a second connector on a second lateral side thereof. The first connector and the second connector enable forward and rearward rotation of the upper torso portion relative to the lower seat portion (as in the case of forward and rearward bending by a user of the harness) without causing a significant increase in tension in the lower seat portion. A safety harness to be worn by a person which includes at least one strap section including a cam buckle in operative connection therewith to adjust a fit of the strap section. A safety harness includes a label pack system including a base having an attachment mechanism to attach the base to a strap of the safety harness and a closure in operative connection with the base. The base and the enclosure at least partially enclose at least one label (and more typically a plurality of labels) when the closure in a closed state. A safety harness includes a strap section having an interior surface that is adjacent a wearer when the safety harness is worn and an exterior surface generally opposite the interior surface. The interior surface is perceptibly different from the exterior surface so that a wearer can distinguish the interior surface from the exterior surface. A safety harness includes at least one strap section have a first end; the first end including an end member in operative connection therewith, the end member includes a retaining member to connect the end member to the strap or to another strap of the harness.
摘要:
An apparatus and a method are disclosed for reducing a thickness of a thermomechanically-affected layer on an as-machined surface of a hard metal workpiece being machined by a hard cutting tool exerting a thermomechanical load on a surface of the workpiece. The method involves reducing the thermomechanical load on the surface of the workpiece, and the apparatus includes a means for reducing the thermomechanical load on the surface of the workpiece.
摘要:
A method and apparatus for improving the surface finish and/or surface integrity of a workpiece formed or shaped with a tool increase the surface hardness of the workpiece during forming or shaping of the workpiece. A method and apparatus for forming or shaping a workpiece also increase the surface hardness of the workpiece during forming or shaping of the workpiece with a tool, as do a method and apparatus for manufacturing a finished part or product from a workpiece. In some embodiments, an expanding jet of cryogen may be jetted to a surface of a workpiece and a tool from a nozzle, wherein the cryogen is at least partially separated into a condensed phase portion and a vapor portion within a downstream portion of the nozzle.
摘要:
A container for dispensing a viscous agent. The container includes a lid with an upper planar surface having an opening therein. A prophylactic sheath depends from the opening and has an extendable body, a normally open interior and end opening which defines a mouth region. The mouth region is affixed to the lid in proximity to the border of the lid opening. The user can insert one or more fingers within the end opening to extend the sheath for dispensing a viscous agent from the body of the container during use. The sheath can also be afixed to an insert which is installed within the mouth opening of the container.
摘要:
A shingle removing implement can include a flat blade adapted to be inserted underneath the designated shingle, and an elongated handle extending a substantial distance from the blade to cause the blade to exert a lifting action on the shingle. An arcuate plate is secured to the back surface of the blade, to form a wedge structure that facilitates a prying action of the blade on the shingle.
摘要:
A system for creating single and double pane window walls comprising mullions, sills, headers, other framing members and gasketing, is disclosed. The system features window pane framing extrusions which include provisions that allow the extrusions to snap together to create a framing member with a box-type cross-section. Experimentation has shown that the composite box sections have similar structural properties to unitary box sections, i.e. comparable moments of inertia and cross-sectional area and thus comparable ability to carry bending moment, transmit shear and resist buckling.

A cryogenic fluid jet is used in an apparatus and a method for remote cooling of a cutting tool engaged in machining a workpiece under high-energy conditions, such as high-speed machining, hard-turning, cutting of difficult to machine materials, and combinations thereof. The apparatus and method use a stabilized, free-expanding cryogenic fluid jet having a pulse cycle time less than or equal to about 10 seconds. The apparatus and method increase the cleanliness of machined parts and chips and machining productivity of hard but brittle tools, including but not limited to tools which should not be cooled with conventional cooling fluids.
