Extravascular system packaging systems are adapted to facilitate opening of the package and to facilitate one or more auxiliary uses of the packaging systems. Auxiliary uses include the use of at least a portion of the packaging system as a pre-insertion table and as a temporary disposal receptacle. In its use as a pre-insertion table, the packaging system is adapted to provide a stable temporarystorage tool where the extravascular system is readily accessible to the medical practitioner. In its use as a temporary disposal receptacle, the packaging system is adapted to provide a stabilized receptacle adapted to temporarily receive a deployed needle assembly until the needle assembly can be properly disposed of in a sharps container.

The invention relates to the technical field of repairing and remanufacturing of mechanical parts, in particular to a smooth shaft wear repairing process. A lathe adopted in the repairing process comprises a fixed base, first moving mechanisms, second moving mechanisms, a separating plate, third moving mechanisms, fixing mechanisms, drip washing mechanisms and impurity removing mechanisms. According to the repairing process, the two symmetrically-arranged first moving mechanisms, the two symmetrically-arranged second moving mechanisms and the two symmetrically-arranged third moving mechanismsare utilized, so that the double-spindle double-turret lathe is realized, moreover, first rotating columns of double turrets can freely rotate in the machining process, different machines can be freely replaced for machining, and the effects of being convenient and fast are achieved; the drip washing mechanisms are arranged in the positions, on the tops of the fixing mechanisms, of third fixing plates so that scraps on a fixed workpiece can be effectively washed off and can be cleared in time, meanwhile, the effect of effective cooling is achieved, and the machine service life is prolonged; and the scraps which are washed off through the drip washing mechanisms are collected by using cloth bags, and water is filtered out so that the scraps can be prevented from polluting the environment and can be recovered and reused.

The present invention relates to a method for producing a ready-for-use camshaft (1) for controlling valves of an internal combustion engine, comprising a carrier shaft (10), on which an end component (11), for example a drive wheel, a phase shifter or a portion of a phase shifter, is arranged, and comprising a plurality of cam elements (12) which are affixed to the carrier shaft (10) in a fixed position, wherein the method comprises at least the following steps: a) providing the carrier shaft (10) and the end component (11), b) joining the end component (11) to the carrier shaft (10), c) grinding at least the carrier shaft (10) in order to form cam seats (13) so that it is ready for use, d) forming a surface profile (14) in a first cam seat (13), e) providing a cam element (12) having ready-for-use properties, f) seating the cam element (12) on the cam seat (13) provided with the surface profile (14), and g) repeating steps d) to f) with a frequency corresponding to a required number of cam elements (12).

The invention belongs to the technical field of shield construction, and relates to a gantry crane combined beam device and an installation method. Bailey trusses are taken as a beam body, 609 mm steel supports and I45 steel are taken as beam columns to be connected with an existing concrete structure, and members such as angle steel and the like are transversely fixed with retaining structures toenhance the overall stability of the beam body. In order to ensure that tracks are uniformly transferred to the Bailey trusses, I28 I-steel at spacing of 50 cm are used as distribution beams. The whole beam body is composed of steel structures. The bailey trusses are combined in advance before installation. Other members are blanked in position in advance according to the existing structural dimension. After a shield machine is lowered into the well, installation can be completed in 1-2 days by a crane. The device is convenient, fast and safe, does not affect normal tunneling of the shield machine, enables a gantry crane to be put into use in time, and ensures construction efficiency.

A method for managing availability of channel for adaptive layer service in asynchronous transmission mode includes adding an availability management unit of AAL2 channel in RNC and setting fault state flag and manual state flag on each AAL2 channel, detecting whether there is hardware fault or software fault on AAAL2 channel or not in real time by management unit, executing an unblocking operation and detecting state flag of AAL2 channel on set time when operation of device is stared, executing relevant blocking / unblocking operation and revising relevant state flag for lifting off fault AAL2 resource in system timely.

The invention relates to a method for producing a ready-to-use camshaft (1) for controlling the valves of an internal combustion engine, the camshaft (1) having a carrier shaft (10) and a plurality of cam elements (12), Arranged on the carrier shaft (10) is an end part (11), for example a drive wheel, a phase adjuster, or a part of a phase adjuster, a plurality of cam elements (12) in a positionally fixed manner is attached to a bearing shaft (10), wherein the method comprises at least the steps of: a) providing the bearing shaft (10) and an end piece (11), b) joining the end piece (11) to the bearing shaft (10 ), c) grinding at least the carrier shaft (10) to form the cam seat (13) so as to be ready for use, d) forming a surface profile (14) on the first cam seat (13), e) providing A cam element (12) with ready-to-use properties, f) seating the cam element (12) on a cam seat (13) provided with a surface profile (14), and g) matching the desired cam element ( 12) Repeat steps d) to f) the number of times corresponding to the number.

The invention relates to a high-strength high-toughness grinding wheel ceramic bonding agent and a preparation method thereof. The preparation method comprises the following steps that silicon dioxide, diboron trioxide, aluminum oxide, lithium oxide, sodium oxide, calcium oxide, zinc oxide, barium oxide and titanium dioxide are mixed to obtain a mixture; the temperature of the mixture is raised to 600 DEG C at the temperature raising speed of 6-9 DEG C / min; then the temperature is raised to 1200 DEG C at the temperature raising speed of 3-6 DEG C / min; then the temperature is raised to 1450 DEG C at the temperature raising speed of 2-3 DEG C / min; then heat preservation is conducted; then an SG abrasive is added, heat preservation is continued, and molten liquid is obtained; and after the molten liquid is subjected to water quenching, wet grinding is conducted, then drying, smashing and dry grinding are conducted, the mixture passes through a 200-mesh sieve, and the high-strength high-toughness grinding wheel ceramic bonding agent is obtained. According to the high-strength high-toughness grinding wheel ceramic bonding agent and the preparation method thereof, a preparation method for a ceramic bonding agent is improved with microcrystal toughening and the operation that Al2O3 serves as a network intermediate to enhance a glass network structure as the theoretical basis, the obtained ceramic bonding agent has the characteristics of high strength and good toughness, and the requirements of preparation and usage of a CBN grinding wheel are met.
