A carrier for a plurality of beverage containers has a carrier body, means for hand carrying the carrier, and pull tabs. The carrier body has an outer periphery and defines a plurality of container openings with one container opening for each beverage container of the plurality of beverage containers. There is a plurality of pull tabs with one pull tab for each container opening of the plurality of container openings. Each pull tab extends from the outer periphery to an associated container opening and is connected to the associated opening by perforations extending from the associated opening to the outer periphery so that pulling the pull tab separates the body at the associated opening creating a path for container removal.

Provided is a universal type high speed intelligent automatic screw fastening mechanism. The mechanism can be used for conducting continuous accurate screw fastening operation in the transverse direction, the inclined direction and the direction from bottom to top at any angle. The mechanism mainly comprises a screw pushing device, a screw absorbing device and a screw fastening device. When the mechanism works, a screw is blown to the screw pushing device by a screw supply mechanism through a flexible material pipe and is placed in accurate gesture. After the screw pushing device pushes the screw in place, a screw cylinder control vacuum straw in the screw absorbing device is utilized to move towards the screw placing position, simultaneously a vacuum generator acts to absorb the screw and achieve absorbing screw installation. The screw fastening mechanism resolves the problem that the screw recessed position center cannot be aligned with the screw blade center in the screw fastening operation in the transverse direction and the like, inclination occurs in the screw fastening mode, and poor products appear. After the screw is absorbed by the absorbing device, the screw fastening device is moved towards a product to be processed under the effect of the cylinder, a screw driver rotates to locking the screw tightly to finish operation. The mechanism is convenient and quick and greatly improves working efficiency.

The invention discloses a preparation process and application of green environment-friendly paper, belonging to the field of environment-friendly papermaking technology. According to the invention, a Chinese ink coloring apparatus is employed for uniformly coating the surface of a semi-dried paper web with a color coating in a full-web Chinese ink coloring manner; since the paper web has moisture, the paper web well absorbs Chinese ink during coloring, and a uniform color coating can be formed; thus, green environment-friendly myopia-preventing homework books, exercise books and examination paper of students prepared from produced paper through printing protect the eyesight of students from damage in use of the books and examination paper. A paper machine is employed for drying, compacting and synchronous dye fixation, so the coating on the surface of the paper is fully fused with the paper and is free of peeling. The whole process flow is integrated with a papermaking procedure, the semi-dried paper web is directly subjected to full-web Chinese ink coloring and then to further drying, and the papermaking procedure is integrated with the drying part of a coloring procedure, so drying time is reduced, energy needed in drying is saved, and high efficiency and energy conservation are realized. Produced wastewater is simple in composition and easy to treat.

The invention provides a method for manufacturing a non-linear crystal gallium selenide component, relates to a method for manufacturing crystal components, and aims to solve the technical problems that existing GaSe crystal has low transmittance and is easily deformed and split when being used. The method comprises the following steps: 1, etching the surface of GaSe crystal ingot, cleaning and drying; 2, putting the crystal ingot into a boat, putting the boat in the middle of a quartz tube, and putting GaSe polycrystal powder at two ends of the boat; or putting the GaSe polycrystal powder at one end of the boat, and putting Se at the other end of the boat; vacuumizing the quartz tube, sealing, and putting into a resistance furnace in a single-temperature region; 3, annealing; 4, cutting the annealed crystal ingot, and trimming to form a GaSe crystal block along the C-axial direction; and 5, fixing the GaSe crystal block at the hole of a metal base with glue, coating a polytetrafluoroethylene coat, adding an upper cover, and connecting the base and the upper cover with a fixed nut to obtain a GaSe component. The component can be used in a laser.

The invention discloses a ceramic oxidation tube for the analysis of natural gas carbon isotopes, and aims to provide an oxidation tube with good oxidation effect, stable analysis data and long service life. There are copper oxide particles, and the particle size of copper oxide particles is 0.3-0.5mm; the inner diameter of the pipe is 1.2-1.5mm, and there are also pure copper particle areas on both sides of the high-temperature area in the pipe; the oxidation pipe of the present invention is used for natural gas carbon isotope analysis experiments .
