Abstract: A utility marker for use on any sort of vertically suspended electrical wires or pipe to establish a visual awareness. The inventions comprises of an elongated tubular member of a relatively rigid plastic having a hollow interior throughout its length. The tubular member has a slit extending longitudinally thereof between opposite ends. This is to allow the tubular member to be in surrounding relationship by being moved laterally over the electrical wire or pipe with the hollow interior accessible through the slit. First and second generally diametrically opposed aligned apertures are located adjacent the first end of the tubular member. This is so that they can be aligned with the electrical wire or pipe. This allows the marker to be wrapped over the electrical wire or pipe in with applied pressure and twisting.

Abstract: A self propelled lawnmower protective component used to support the grass catcher door is formed of a plastic material that is more flexible than the polyethylene material used in the prior art. By using co-extrusion, two different plastics are extruded into one shape. When applied to the lawnmower structure, the adhesion between the basic profile and a co-extruded ball or flap is extremely tight. Metallocene olefin is the plastic material which, when compressed under load and heat, recovers its original shape, similar to a soft rubber product and still has the capability of adhering to the polyethylene profile, so as not to separate after continuous or repeated use.

By using co-extrusion, two different plastics are extruded into one shape. When applied to the lawnmower structure, the adhesion between the basic profile and the co-extruded ball is extremely tight. TPE is the plastic material which, when compressed under load and heat, recovers its original shape, similar to a soft rubber product and still has the capability of adhering to the polyethylene profile, so as not to separate after continuous or repeated use and still return to its original shape. An additional volume of TPE may be formed within the ball to provide mechanical strength. The TPE used is SANTOPRENE®.

Abstract: A flexible hinge consisting of a single piece of rigid plastic material includes a thin flexible web portion between two inflexible end members, with flexible plastic material layers being bonded to opposing top and bottom faces of the web.

Abstract: A process for making a drag shield for a lawn mower includes forming from a rigid plastic material a relatively inflexible first end member adapted for secure attachment via a connecting element to an associated lawn mower deck, and a relatively inflexible second end member with a web portion extending therebetween for connecting the first and second end members. The web is formed from a rigid plastic material having a sufficiently thin and substantially uniform cross section for maintaining flexibility. The web and first and second end members are integral and provided in a single piece of rigid plastic material. The process further includes forming first and second layers of flexible plastic material on opposing sides of the web portion.

Abstract: Paint rollers are formed in a continuous process. A plastic material is delivered from pellets or powder to an extruder and then, directly from the extruder to an internally cooled mandrel. The heat of the extrusion process provides the sealing temperature between the fabric cover and the plastic strip. No additional heat source is required to soften the surface of the core. The method incorporates single extrusion or tandem or co-extrusion techniques in fabricating paint rollers where an additional layer of tacky plastic material is bonded to the surface of a base layer of plastic material to enable the fabric cover to adhere to the roller.
