A prosthetic constraining device for use with a hip replacement prosthesis that includes an acetabular cup assembly adapted to be bonded to a patient's pelvis and a femoral stem adapted to be bonded to the patient's femur, where the femoral stem includes a ball component at its proximal end received within the acetabular cup assembly to form a ball joint type coupling, and where the constraining device includes a ring having a central aperture, where the ring is adapted to be mounted to a rim of the acetabular cup assembly so that the femoral stem passes through the central aperture, where the diameter of the central aperture is less than the diameter of the ball component on the proximal end of the femoral stem so that the ring assists in maintaining the ball joint type coupling between the acetabular cup assembly and the femoral stem, and where the ring comprises a biologic material, a biologically reabsorbable material and a combination of biologic, or biologically reabsorbable materials.

The invention presents yttira elements containing high-density chrome based refractory composites, which consist of: (A) Fused polymeric compound as aggregate, containing: 40 to 50 wt % of particles in size from 1 to 4 mm and 15 to 25 wt % of particles in size below 1 mm; (B) A matrix consisting of fused polymeric compounds with particle sizes below 66 μm, active sintered Al₂O₃, active industrial Cr₂O₃ and Y₂O₃. (C) Binders accounting for 2.5 to 3.5 wt %. Since Y₂O₃ has resistance to the slag corrosion and penetration with its compatibility with slag, it has been introduced to activate the major component Cr₂O₃ crystal lattice in favor with Al₂O₃ so that it helps to reduce the sintering temperature, increase the rate of finished products as well as reduce the manufacturing cost.

An aircraft refuelling system of an aircraft is provided. The refuelling system comprises a refuelling connector (34) mounted as part of the aircraft and configured to detachably connect to the fuel outlet (2) of a fuel supply apparatus separate from the aircraft, and a fuel pressure regulator (36) having an inlet in communication with a fuel inlet (35) of the refuelling connector (34) and having an outlet in communication with refuelling pipework (39) of the aircraft. The fuel pressure regulator (36), regulates the pressure of fuel in the refuelling pipework (39) when fuel is being passed into the refuelling pipework (39) from the fuel inlet (35) of the refuelling connector. A fuel pressure regulator apparatus for mounting in an aircraft, comprising a connector forming a fuel inlet to the fuel pressure regulator apparatus, configured to detachably connect to the fuel outlet of a fuel supply system, a fuel outlet for connection to the refuelling pipework of an aircraft and a fuel pressure regulator for regulating the pressure of fuel passing through the fuel outlet is also provided.

The invention discloses a dual constraint based selection calling method of an LOD (Level of Detail) model in a three-dimensional scene. The dual constraint based selection calling method comprises entering into the three-dimensional scene; obtaining a viewpoint coordinate of a user and a center coordinate of the current object in the three-dimensional scene; calculating the sight distance and judging whether the current object is within the field of view of the user or not; calculating the interest degree of the user of a three-dimensional model and calling the user required level number of the current object model; combining with the distance constraint condition to select to call the user required LOD model of the current object; rendering and drawing the selected model; judging whether objects in the three-dimensional scene are traversed or not. According to the dual constraint based selection calling method of the LOD model in the three-dimensional scene, the LOD model can be selected to be called based on the interest degree and the distance, the requirements for the high image quality of the high interest degree of object of the user are met, meanwhile the weakening treatment is performed on the low interest degree of object of the user, and the rendering speed of a system is improved under the condition that the basic visual demand of the user is satisfied.

An exercise and physical therapy device using inertia and momentum to provide both resistance training and passive assisted movement for a user's foot or feet. A foot pedal is mounted for pivoting movement in a frame. The pivoting movement of the foot pedal is translated into rotational movement of a flywheel. As a user begins pivoting motion of the foot pedal, the flywheel provide resistance to this movement. The user may continue to use the foot pedal for resistance training. Once the flywheel is in motion a user may rest a foot or feet on the foot pedal and the rotational movement of the flywheel caused by the flywheel's momentum will cause pivoting motion of the foot frame. This presents passive assisted movement to a user's foot and legs until the momentum of the flywheel is dissipated.

The invention relates to equipment and process for manufacturing a flexible circuit board in the technical field of manufacturing of an electronic circuit board. The equipment comprises an elongate framework type machine body, wherein an automatic operating platform is arranged at a top part of the framework type machine body and comprises a control panel, an automatic feeding part, an automatic lamination part, an automatic rolling cutting part, a splitting mechanism, a traction mechanism and a winding mechanism, the automatic feeding part comprises a bottom membrane feeding mechanism, an elongate conductor feeding mechanism, a combination medium membrane feeding mechanism and a cover membrane feeding mechanism, the automatic lamination part comprises a first lamination mechanism and a second lamination mechanism, and the automatic rolling cutting part comprises an upper rolling cutter mechanism and a lower rolling cutter mechanism. Compared with a traditional punching or etching process, the process employing rolling cutting has the advantages that an irregularly-shaped cross section and a clearance hole can be synchronously cut in a rolling way, the rolling cutting efficiency is high, no stop is needed during the rolling cutting process, assembly line type processing can be directly completed, so that the production working efficiency of a product can be improved, labor investment is greatly reduced, and the qualified rate and the accuracy of a finished product are improved.
