A ferrite-core holder, fabricated by casting an elastomer in a simple mold, simplifies the assembly of modular matrix units for computers. Use of the device permits the core leads to be multiply threaded and soldered to terminals, without requiring intermediate terminals.
Sheet and waste cork are cemented together to provide a tooling pattern or mold. The cork form withstands moderately high temperatures under vacuum or pressure with minimum expansion, shrinkage, or distortion.
Transfer, injection, and compression in pressure molding for electronic components
Compression molding of molecular salt-like intermediate Pyrrone powders by two pressure method, noting volatiles elimination
Unfilled Pyrrone prepared from powder into molded parts for flexural tests at elevated temperatures observed for stability to electron irradiation in air
Preparation and characterization of low DP end-capped pyrrone moldings
Orientation of crystallites in molded artificial graphites
Hand-operated tool positions and seats window piece and conductor spacer onto conductors of two stripped cables during process of terminating cables with molded plug. Tool accommodates cables up to 3 in. wide and is used in conjunction with folding tools.
Vacuum method for molding thermosetting compounds used as ablative materials
Thermal stresses in chemically hardened elastic media and applications to molding processes
Method of making molded electric connector for use with flat conductor cables
Approximation of residual thermal stresses in flat sheet molded from chemical hardening materials
Orientation and distribution of crystallites in molded artificial graphite
Cold metal hydroforming techniques using epoxy molds for counteracting creep or stretch
High temperature pyrrones molding, discussing covalent organic bonds breakage and subsequent structural rearrangement of crosslinked polymer network
Sounding rockets motors with integrally molded plastic case and nozzle, discussing cost effectiveness and demonstration tests
Toluene diisocyanate-based polyurethane produces molded-to-size foam products. Formulation techniques optimize dimension stability, strength and moldability.
Process permits molding of longer, thinner bodies, such as cylindrical rocket motors, while maintaining equal or superior physical properties. Major advantages of process are presented.
