Polyester polymer is recovered from polyester fibers (in the form of filaments, yarns or fabrics and the like, both dyed and undyed), and used in the production of new undyed fibers, films, and other polymer products by the process of stripping the dye from the dyed polyester fibers and dissolving the polyester fibers in a solvent in a separate but functionally interrelated (with the dye stripping...

A ski fastener structure has a rigid bar element removably fixable to a ski and engaging the lower end of a rod element pivotable about a horizontal axis substantially perpendicular to the ski longitudinal axis. The rod element is effective to resiliently encircle a rear region of the skier's leg at the middle area of the tibia and the skier's footwear is removably connected to the bar element.

PURPOSE:To atomize and pulverize a molten metal to about several microns by exerting a compressive stress to nozzle terminals to close said terminals and to enable narrow and uniform opening of an injecting annular band according to the pressure of a liquid and providing an evacuating chamber in the lower part of said band. CONSTITUTION:An injecting annular band formed of nozzle terminals 1, 2 is ...

An electrical connecter for use with a flat electrical cable (100), comprises a housing formed of two members, one of which forms a cover (11) capable of providing strain relief for connections between the cable and terminals carried by the other housing member (1).

A continuous process for simultaneously drying, thickening and increasing the flowability and processibility of polycarbonate powders is disclosed. The powders are fed to a tubular drier equipped with a mechanical stirrer in which they are fluidized with the aid of a stream of heated inert gas or vapor flowing counter-currently to the powders.

A coating composition for polyolefinic products, particularly films, which consists essentially of a solution of a three-component polymeric system comprising: (a) a vinyl or vinylidene copolymer; (b) a polymer or copolymer of acrylic esters; and (c) a polyester resin obtained by condensation. The coated products and the coating process are also described.

An apparatus for deburring workpieces such as profiles, tubes, metal sheets or the like, is provided which includes a housing and a deburring tool rotatably mounted within the housing about a horizontal axis such that the tool partially projects from the housing. A workpiece holder is located in front of the housing for holding the workpiece to be deburred level with and in abutment with the rotat...

Disclosed is a process for producing fiber-reinforced elastic articles comprising: 1 to 20 parts by weight of 1,2-polybutadiene fibrils dispersed in a matrix of 100 parts by weight of a rubber material. In the process, the 1,2-polybutadiene in the form of particles are dispersed in the matrix of rubber material; the dispersion is extruded through a die at a temperature of at least 5 DEG C. above ...

A process for the manufacture of cross-linked foamable moldings from olefin polymers, wherein the olefin polymer is mixed with (A) A SOLID ORGANIC BLOWING AGENT WHICH ELIMINATES GASES WHEN HEATED, (B) AN ORGANIC PEROXIDE, (C) CONVENTIONAL ADDITIVES AND (D) AN ACTIVATING ORGANIC COMPOUND WHICH LOWERS THE DECOMPOSITION TEMPERATURE OF THE PEROXIDE, AND THE MIXTURE IS MOLDED THERMOPLASTICALLY AND IS C...

Polyamide materials for the construction of protheses and surgical sundries are made biocompatible by inducing a superficial hydrolysis by treating such materials, either raw or in the form of shaped articles, with a normal multiple solution of hydrogen chloride. Thrice normal or fourfold normal solutions are preferred and the treatment time being a function of the temperature. At human body tempe...

The invention relates to a thermally insulating composite wall for any kind of tank on ships or on land. The wall comprises a self-supporting external wall, a bed of thermally insulating elements secured to said wall at least partially by means of a hardened packing material and a fluid-tight internal lining; said material may notably be a cellular material in contact with all the external surface...
