A bio-compatible femoral stem is made from a bio-compatible titanium alloy or cobalt-chromium alloy, each of which have an elastic modulus far greater than that of natural bone. When the implant heals within a bone cavity, the implant essentially carries substantially the entire load. Transfer of load to the surrounding bone tissue is lost or resorbed due to lack of use after implant healing. Flexing a stiff implant applies a very large load at the implant distal end. The bone cortex is thereby allowed to thicken due to excessive load, causing thigh pain long after implant healing. The femoral implant has a bone ingrowth coating on the proximal end, allowing firm attachment of the implant in the bone cavity. The distal end has a central aperture and a helical machined groove that permits flexing of the distal portion of the femoral implant stem. This flexing is occurs in a manner similar to surrounding bone tissue, preventing thigh pain.

The invention belongs to the solvent extraction and rare earth separation technology, and relates to a pre-separating and high-purity three-outlet extracting method. The method comprises the pre-separating technology and the high-purity three-outlet extracting and separating technology. The pre-separating technology comprises a pre-separating and extracting section 1, a pre-separating and washing section and a pre-separating and extracting section 2. In the high-purity three-outlet technology, a third outlet serves as the boundary, the side close to an outlet water phase is a section hard to extract and separate, and the side close to an outlet organic phase is a section easy to extract and separate. According to the pre-separating and high-purity three-outlet extracting method, the pre-separating and extracting principle is adopted, multi-component raw materials are pre-separated, and the high-purity three-outlet technology is conducted through multiple ports. The content of components A easy to extract in the outlet water phase of the pre-separating and extracting section 1 and the outlet water phase of the pre-separating and extracting section 2 is controlled to be very low, the content of components C hard to extract in the outlet load organic phase in the pre-separating and washing section is controlled to be very low, high-purity products can be obtained at the third outlet, and therefore the quality and direct recovery rate of intermediate products can be improved. The overall technology treatment capability is improved, and the tank storage number of extraction agents and rare earth metals is reduced; and control is easy, the products are stable, acid-base consumption and waste water discharge are reduced, and environment friendliness is facilitated.

The invention provides an aerated block drilling and pipe arranging construction technology, and belongs to the technical field of building construction. The aerated block drilling and pipe arranging construction technology comprises the following steps that S1, deep design is carried out, specifically, a detailed brick arrangement drawing and a pipeline and wire box positioning arrangement drawing are provided; S2, centralized construction is carried out, specifically, according to the brick arrangement drawing and the pipeline and wire box positioning arrangement drawing, hole forming machining is carried out on building blocks; S3, paying off of building bodies is carried out, specifically, a building body construction control line, an electric box horizontal center position line, an electric box horizontal side line and the like are popped up; S4, water and electricity pipelines are installed; S5, brick arranging and positioning are carried out, specifically, the mortar joint width between the bricks is adjusted according to the brick arranging drawing and the pipeline and wire box positioning arrangement drawing; and S6, brick casing pipe matching is carried out, specifically, according to the building body width, the water and electricity pipeline specification and the pipeline number, a building block middle drilling casing pipe is adopted.

A connecting terminal having an insulating housing, a conductor insertion channel extending toward a conductor insertion axis with an at least partially circumferential conductor channel wall arranged coaxially to the conductor insertion axis, and an actuation channel disposed adjacent to the conductor insertion channel. A leg spring bent in a U-shape has a contact leg, a clamping leg and a spring bow. A push button is adapted to be received in the actuation channel in a longitudinally displaceable manner. The contact leg is mounted on the bus bar, and a clamping edge of the clamping leg forms a spring clamp connection with a contact region of the bus bar for clamping an electrical conductor inserted in the conductor insertion channel. An actuation axis defined by a displacement direction of the push button and the conductor insertion axis are aligned with each other at an angle of 5° to 30°.

A method and an apparatus for dispensing liquid material to a substrate comprising a housing having a bore and an inlet for supplying liquid material from a material source to the bore. A nozzle communicates with the inlet and includes a discharge opening for dispensing the liquid material. A movable plunger is mounted for reciprocal movement between a closed and an open position. In the open position, liquid material is dispensed from the discharge opening and in the closed position, liquid material is prevented from being dispensed from the discharge opening. An actuator moves the plunger between the closed and the open position. The plunger has at least one slot extending from the outer periphery toward the center of the plunger.
