51 results about "Joint problems" patented technology

Other types of arthritis include gout or pseudogout. Sometimes, there is a mechanical problem in the joint, such as torn cartilage, that causes pain or limits movement in the joint. Types of joint problems that affect the soft tissues like muscles, tendons, and ligaments include: Rotator cuff injuries.

System for performing coupled finite analysis

A graphical user interface, together with a comparable scripting interface, couples a plurality of finite element, finite volume, or finite difference analytical programs and permits iterative convergence of multiple programs through one set of predefined commands. The user is permitted to select the joint problem for solution by choosing program selections. Data linkages that couple the program are predefined by an expert system administrator to permit less skilled modelers access to a comprehensive and multifaceted solution that would not be possible for the less skilled modelers to complete absent the graphical user interface.

Prefabricated T beam and construction method

The invention discloses a prefabricated T beam and a construction method. The prefabricated T beam comprises bridge panels, a longitudinal beam and a steel transverse partition plate. The bridge panels and the longitudinal beam are prefabricated parts. The adjacent bridge panels are connected in an embedded mode. The portions, at the upper end of the longitudinal beam, of the bridge panels are evenly provided with preformed holes. Pre-buried deformed steel bars are arranged inside a bridge beam of the longitudinal beam. A pre-buried steel plate is arranged on the side face of the longitudinal beam. The pre-buried deformed steel bars need to stretch out of the upper edges of the spliced bridge panels on the basis of the length. The steel transverse partition plate is fixedly connected with the pre-buried steel plate on the longitudinal beam. The construction method comprises the steps of prefabricating the bridge panels and the longitudinal beam; connecting the steel transverse partition plate with the longitudinal beam after the longitudinal beam is suspended to a bridge pier and abutment; placing the bridge panels on the longitudinal beam, and connecting the adjacent bridge panels in the embedded mode; pouring epoxy mortar concrete into the preformed holes. The bridge panels and the longitudinal beam of the T beam are partially prefabricated separately, and therefore the wet joint problem existing in concrete T beam splicing is effectively solved.

Injection mould and Injection molding method

The invention provides an injection mould and an injection molding method. The injection mould comprises a moving template and at least moving mould insert arranged on the moving template according toa predetermined position. According to the invention, on the basis of cooperation of the moving mould insert, a waterway, and a gas circuit, air in a mould cavity can flow out, so that mould exhausting is enhanced; the temperature of the moving mould insert during the injection molding process is ensured; because the mould is heated before injection and pressure maintaining, a phenomenon that mobility of the material flow is affected because of too low material flow temperature caused by heat losses of the material flow due to heat transferring and thus a hungry joint problem of an injectionmolding part is avoided. Besides, after injection and pressure maintaining, the mould is cooled by the heat exchange with the waterway, so that the cooling speed and the thermal insulation effect of the mould are controlled; and the material flow temperature is controlled and the material flow flowing efficiency is increased, so that the moulding quality of the thin wall region of a to-be-mouldedelement and the yield of the to-be-moulded element are improved effectively.
