The process for extraction consists the steps of, identifying the source of the raw material, extracting and concentrating the raw material, mixing the extractive with thin layer silica gel by the proportion of 1:1, loading column by the ratio of sample : thin layer chromatography silica gel = 1:0.5, and washing with expansion agent. The invention realizes an extraction process with an increased standard body purity.

A process for constructing a wall, floor or ceiling in situ. The process includes the steps of erecting a substantially rigid frame (10) and attaching fiber reinforced cementitious sheets (50) to the front and rear faces of the frame to form a void (60) therebetween. This void (60) is then filled with a lightweight aggregate concrete slurry and allowed to cure. The sheets are adapted to absorb sufficient moisture from the lightweight aggregate slurry to provide natural adherence of the concrete slurry to the sheets without substantially losing their structural integrity during setting and curing of the concrete slurry. Further, The invention provides a wall produced by the same process.

An automatic control device for online removing of tiny burrs on the working edge of a valve element of a servo valve comprises a deburring tool system, a precision feeding system, an automatic tool setting system, a force feedback system and a control system, wherein the deburring tool system mounted on a Z-axis lifting table comprises a deburring turning tool, a force sensor and a fixture, the precision feeding system used for controlling the feeding of the deburring tool system comprises an X-axis feeding mechanism, a Y-axis feeding mechanism and the Z-axis lifting table, the automatic tool setting system comprising a displacement sensor fixed on the fixture can achieve precise tool setting and complete radial runout measurement and working edge scanning detection of a workpiece, the force feedback system used for monitoring the degree of the deburring force in real time comprises a force sensor which is arranged below the deburring turning tool and connected with the fixture, and the control system used for monitoring the feeding movement, automatic tool setting, deburring, force feedback alarm retraction and online deburring effects of the automatic control device comprises an industrial personal computer connected with the precision feeding system, the force feedback system and the automatic tool setting system. The automatic control device for the online removing of the tiny burrs on the working edge of the valve element of the servo valve achieves the online automatic removing of the tiny burrs on the working edge and has the advantages of low rejection rates, high efficiency and low costs.

The wire bond structure of sophisticated metallization systems, for instance based on copper, may be provided without a terminal aluminum layer and without any passivation layers for exposed copper surfaces (212S) by providing a fill material (250) after the wire bonding process in order to encapsulate at least the sensitive metal surfaces (212S) and a portion of the bond wire (230). Hence, significant cost reduction, reduced cycle times and a reduction of the required process steps may be accomplished independently from the wire bond materials used. Thus, integrated circuits requiring a sophisticated metallization system may be connected by wire bonding to the corresponding package (260) or carrier substrate with a required degree of reliability based on a corresponding fill material (250) for encapsulating at least the sensitive metal surfaces (212S).

The present invention relates to an assembled concrete barrier, comprising anti-crash tubes mounted on the ground and anti-crash blocks sleeved on the anti-crash tubes. An elastic bump is provided on the outer wall of each anti-crash tube; each anti-crash block is provided with assembling holes, and an assembling clamping groove is formed in the inner wall of each assembling hole; the shape of the assembling clamping groove and the shape of the elastic bump are the same; the anti-crash tube penetrates into the assembling hole of the anti-crash block; the elastic bump is embedded into the assembling clamping groove. The present invention further relates to a mounting method for the assembled concrete barrier, comprising the following steps: reserving a mounting clamping position on the ground; enabling a mounting bump on an anti-crash tube to pass through a through groove and then rotating same by a certain angle, so that the mounting bump is clamped in a second hole position; pouring polyurethane elastic concrete, polystyrene foam concrete, or a fiber reinforced composite material into a central through hole of the anti-crash tube; and sleeving an anti-crash block on the anti-crash tube, so that an assembling hole is matched with the anti-crash tube, and an assembling groove is matched with an elastic bump. The present invention relates to the technical field of concrete barriers, and can reduce crash damage to the road surface.
