Branched hose construction, joint construction and part therefor, and

A railroad track insulator, part therefor and methods of making the same are provided, the railroad track insulator being adapted to hold a railroad rail against its foundation and comprising the combination of a metallic part and a polymeric part secured together so that the polymeric part is adapted to engage the rail. The metallic part has an open ended recess in one of the opposed sides thereof and is defined by a peripheral flange arrangement thereof. The polymeric part has a peripheral edge and is disposed and secured in the recess so as to have the peripheral edge thereof supported by the peripheral flange arrangement of the metallic part.

Method of making a railroad track insulator unit

A method of making a branched hose construction is provided and comprises the steps of providing a first tubular member having opposed ends, providing a second tubular member having opposed ends, forming the first tubular member to have an opening therein intermediate the opposed ends thereof, providing a joint construction that comprises a tubular insert having opposed ends, joining one of the ends of the second tubular member to the opening by having one end of the tubular insert disposed through the opening and the other end thereof interconnected to the one end of the second tubular member whereby the tubular members are in fluid communication with each other through the tubular insert and the second tubular member branches outwardly from the first tubular member, forming the joint construction to further comprise a washer-like member, telescoping the washer-like member on the tubular insert, and mechanically clamping the one tubular member between the washer-like member and the one end of the tubular insert completely around the opening thereof.

A branched hose construction, a T-connector therefor and methods of making the same are provided, the branched hose construction comprising T-connector having a body portion provided with a pair of substantially oppositely directed legs extending therefrom and an outwardly directed branch leg extending therefrom intermediate said pair of legs, and three tubular hoses respectively telescoped onto the legs to be disposed in fluid communication with each other through the T-connector, the body portion of the T-connector having an annular shoulder adjacent each leg thereof against which an annular end surface of its respective hose abuts and which is of a size that causes the external peripheral surface of that respective hose to substantially mate with and thereby be substantially flush with the external peripheral surface of the body portion that is adjacent that respective hose.

A railroad track insulator, part therefor and methods of making the same are provided, the railroad track insulator being adapted to hold a railroad rail against its foundation and comprising the combination of a metallic part and a polymeric part secured together so that the polymeric part is adapted to engage the rail. The metallic part has an open ended recess in one of the opposed sides thereof and is defined by a peripheral flange arrangement thereof. The polymeric part has a peripheral edge and is disposed and secured in the recess so as to have the peripheral edge thereof supported by the peripheral flange arrangement of the metallic part. The metallic part comprises a stamping that has a generally L-shaped cross-sectional configuration that defines two legs thereof being disposed at an angle relative to each other, each leg having opposed ends and an outer free end extending between the opposed ends thereof. Each end of each leg has a part of the peripheral flange arrangement bent therefrom and being spaced from adjacent parts of the peripheral flange arrangement.

Railroad track insulator and part therefor

A laminated printing blanket having compressible and resilient properties and a method for its production are provided. The compressible characteristics are provided by disposing a compressible intermediate layer having voids, between a base ply and a surface layer. The voids in the intermediate layer are produced by dispersing a blowing agent in an elastomer, sandwiching the elastomer containing the blowing agent between two fabric layers, and activating the blowing agent to produce voids. By activating the blowing agent before disposing the intermediate layer between the base ply and the surface layer, the gases from the blowing agent are prevented from migrating to the base ply or to the surface layer.

Method of making a compressible printing blanket and a compressible

A center plate structure for a railway vehicle is provided which utilizes a polymeric wear-resistant tubular liner disposed in sandwiched relation between a cylindrical outside surface of a center plate of the body of the railway vehicle and a cylindrical inside surface of an upstanding peripheral flange of an associated bolster bowl of a truck of the railway vehicle wherein a continuous uninterrupted metal ring is fixed against a top portion of the inside surface of the flange with the ring serving to engage the top surface of the polymeric liner and prevent vertical cold flow of the polymeric material comprising same from between the cylindrical surfaces.

Center plate structure for railway vehicle

A method of resisting wear between a body center plate of a body bolster of a railway vehicle body and a bolster bowl of a truck bolster of a truck of the railway vehicle is provided by disposing a wear resistant tubular liner to be sandwiched between the cylindrical surfaces of the body center plate and the bolster bowl. The tubular liner comprises an ultra high molecular weight polymeric material and has a top surface. A continuous metal ring is fixed to the flange of the bolster bowl against a top portion of the inside surface thereof before the liner is disposed in such bowl. The ring serves to engage the top surface of the tubular liner and prevent vertical cold flow of the polymeric material thereof from between the cylindrical surfaces.
