Abstract: ABSTRACT         A torsional vibration damper and method and apparatus for its manufacture.  The outer inertia member carries a radially inwardly extending web, the web sand-wiched by a pair of elastomer members.  A two-piece hub sandwiches the elastomer members, the two hub pieces being held together as by swaging or by rivets.  Tooling for the swaging mode of assembly is shown such that the elastomer members are deformed from an original to a final configura-tion, and the swaging then accomplished with a single continuous movement.  The swaging assembly apparatus for the device includes Belleville springs, the apparatus limiting the maximum force applied to that portion of the hub members controlling the assembled elastomer thickness.  The damper configuration facilitates low specific energy dissipation and large elastomer-to-metal interface area to thus tend to lower shear stress in the elastomer.  In addition, should the elastomer fail in use, the damper inertia mass is mechanically constrained to remain with the hub assembly.          The two hub pieces cause radial extrusion of the elastomer, the extruded portions contacting the inertia member, the latter guiding and defining the extrusions.

Granted: 1982-07-20
Abstract: An automobile windshield is manufactured by laminating a pair of curved glass sheets with an interlayer film.  The interlayer film is manufactured by heating a ribbon interlayer film to an elongatable temperature while continuously transferring the film and winding the interlayer film up on a cone shape drum while elongating the film with a varying elongating distribution in the transverse direction so as to curve the interlayer film in longitudinal direction.  The tinted part is formed at upper end in parallel to the edge of the windshield by elongating the ribbon interlayer film with varying elongating distribution in the transverse direction.

Abstract: ABSTRACT           The present invention relates to refrigerated display cabinets and more particularly to an electrically heated door structure for use In such cabinets.   The use of an optically transparent electrically conductive coating for preventing moisture condensation of the frontmost glazed surface of a refrigerated cabinet door window is previously known.  Once the door is fabricated, the electrical resistance of the door window heating coating is fixed.  To prevent condensation and frost from forming on the door frame, it is known in the art to provide electrical heating elements concealed within a groove within the door frame structure.  Normally, once the heating element in the door frame has been installed, its electrical resistance is also fixed.  Prior to the present invention, it has been known to connect the heating element in the door frame to the window heating element in either series or parallel con-nection depending on the environment in which the door would be operated, but the interconnection was not thereafter alterable without disassembling the door.  The present invention premits the door to be operated selectively at a plurality of power settings, providing respectively higher and lower levels of electrical heating.          A switching means is used to alter the electrical interconnection of the door window heating elements with the door frame heating elements from a series connection to a parallel connection.  In one embodiment  an automatic electrical controller actuates the switch in response to changes in the ambient humidity and temperature.
