摘要:
A container capable of suppressing the unexpected opening of a pair of upper walls including a first side wall and a second side wall facing each other; a third side wall provided therebetween; a first upper wall and a second upper wall; and a locking member. The first side wall and the second side wall face each other. The first upper wall and the second upper wall are configured to be rotatable with respect to the first side wall and the second side wall, respectively. The locking member includes a fixed portion and an engagement portion, the fixed portion being fixed to the third side wall, the engagement portion being engaged with at least one of the first upper wall and the second upper wall to prevent the first upper wall and the second upper wall from opening.

The invention provides a powder coating composition comprising of thermoplastic polymers, ceramic particles, and cermet particles for lowering the friction coefficient, and improving wear and corrosion resistance of coated surfaces in high-temperature, high-pressure, and corrosive environments. It also provides a method of coating application for improving adhesion of the coating to the substrate. The coating compositions are devoid of volatile organic solvents and can be applied on surfaces using thermal spraying, compression molding and other particle sintering approaches. A multilayer architecture consisting of an adhesive bottom layer and a non-adhesive, low friction top layer is disclosed. The coating can be used in oil and gas production and seawater injection.

A method of making a ball, comprising: forming an inner core having a diameter of about 0.5 inches or lower; forming a plurality of outer core parts from an elastomeric material, each outer core part having an inner surface, an outer surface and at least one non planar mating surface, wherein the inner surface is concentrically disposed within the outer surface and comprises a cavity for receiving the inner core, and wherein the at least one nonplanar mating surface extends radially between the inner surface and the outer surface and comprises a plurality of mating ridges which extend from the inner surface to the outer surface; forming an outer core by mating the outer core parts about the inner core and joining the nonplanar mating surfaces by meshing the mating ridges to form a multi-layer core having a nonplanar parting line which extends about the outer surface circumferentially and intersects with the mating ridges at the outer surface; and molding a cover about the inner core, wherein the elastomeric material has a cohesive strength and the parting line has a mated strength equal to or greater than the cohesive strength.
摘要:
A method for producing a structural component for a vehicle body, the method includes forming a flat carrier material made of a metal, a thermoplastic material and/or a fiber-reinforced thermoplastic material to give a three-dimensional component, and providing a supporting material made of a thermoplastic material, such that the carrier material and the supporting material form an integral material composite. The material composite made up of the carrier material and the supporting material is produced before the carrier material is formed. The material composite is heated before the forming in order to make forming of the thermoplastic material possible. A rib structure is impressed into the supporting material during the forming of the material composite, and the temperature of the three-dimensional component having the rib structure is controlled, it preferably being cooled.
