Patent ES-387050-A1 (ES)
Title: Method for making an elastomeric annular seal with enclosed garter spring
IPC: F16J15/32
Filed: 1971-01-05
Abstract: A mold assembly including an externally-tapered lower core member with an annular groove near the top and an annular shoulder and seat near the bottom and an internally-tapered upper cavity mold member cooperatively form an annular die cavity having the shape desired for the elastomeric annular seal to be formed therein. Prior to molding the seal, the upper cavity mold member is retracted and moved out of alignment with the core member and replaced temporarily by a cylindrical loading device having an annular groove for receiving a pre-tensioned annular hollow helical tension spring and below it a cylindrical end portion adapted to receive an annular charge of elastomer. In carrying out the method of this invention, an annular mounting case is placed on the seat and a collar on the loading device is moved downward so as to push the annular hollow helical tension spring and the annular elastomeric charge from the loading device onto the core member until the spring snaps into the annular groove of the latter. The loading device is then retracted and moved out of alignment with the core member and the mold cavity member moved into alignment therewith and then moved downward into telescoping relationship with the core member, moving the annular hollow helical tension spring downward and at the same time expanding and circumferentially stretching it to open up spaces between its convolutions.

Title: Synthetic fibers and process for making same
IPC: D01D5/247
Filed: 1974-01-19
Abstract: Synthetic filaments having a dull appearance and a feel similar to that of natural fibers, as well as a process for making same, are disclosed. The filaments have an integral skin-core structure, with the core formed of oriented dense polymer and the skin formed of the same polymer, in a fibrous and vesicular form. The filaments are produced by spinning the filaments and quenching the filaments while in the molten state in an inert cooling medium having a temperature of less than 100 DEG C. The inert cooling medium is a swelling agent for the polymer at temperatures above the polymer solidification point and a non-swelling agent for the polymer at temperatures less than 100 DEG C, the degree of swelling progressively decreasing with the decrease of the polymer filament temperature from the polymer solidification temperature to the temperature of the cooling medium. The inert cooling medium is thereafter removed from the surface of the solidified filament, and the filaments are stretched at a draw ratio of at least two.
