44 results about "Longitudinal ridges" patented technology

Longitudinal ridges are vertical ridges in the nail that extend from the cuticle to the top of the nail. Often these ridges will have discoloration, appearing slightly yellow. With the appearance of ridges can also appear increased fragility of the nail, with its becoming more prone to breaking or cracking.

An enhanced multipurpose twist tie is formed with two helically disposed wires encased in a sheath having a polygon shaped cross section, a longitudinal ridges, and detachable end caps. The wires are defined by a longitudinal length and a pair of wire termini. The wires intertwine in a helical configuration along the length of the sheath. The helical configuration compresses the wires together and also allows for a greater concentration of wire to be fit into the sheath. The sheath is defined by an outer face having a plurality of longitudinal ridges that extend along the length of the sheath to provide a grip for facilitated twisting and tying of the twist tie. An inner face has a polygon shaped cross section that restricts longitudinal and rotational slippage by the wires. The end caps detachably attach at sheath termini to form a smooth surface over wire termini.

Method of manufacturing precured tread with reflective grooves

A laminar “precured” or “replacement” tread for wheeled vehicles operating at night on retreaded tires is made more readily visible when grooves in the tires are provided with elastomeric strips or bands in which are embedded retroreflective elements such as transparent glass or synthetic resinous microspheres (referred to herein as “beads”). Upper surfaces of longitudinal ridges in a flat curing mold lend themselves to supporting the strips which are then precisely positioned in grooves defined by the ridges, when the flat tread is cured.

In-line microwave warming apparatus

Microwave warming apparatus includes a housing defining a heating waveguide with a longitudinal ridge and a heating cavity. A slot extends through the ridge into the heating cavity for receiving a cartridge containing a looped tube so that the tube extends into the heating cavity where the tube contents are heated by energy coupled into the waveguide. Receiving waveguides adjacent to the slot sense the thermal radiation emanating from the tube and deliver corresponding signals to a radiometer which produces a temperature indication. The cartridge includes a support member which maintains the shape of the tube loop. A pair of notches in the support member have walls enabling the notches to complete the receiving waveguides in the housing.
