"I planted purple garlic last year. This year, I not only expanded the planting area, but also planted Suzi in the garlic field. More money for selling Suzi will definitely increase the income this year." Recently, farmers in Yanqing County, Beijing Jin Zhongbao said to the author with a smile in the ground.
   Jinzhongbao’s “Purple Garlic†is a high-quality garlic variety “six-petal red†introduced by the new joint venture village of the county in 2011 from Baodi County, Tianjin. After two years of trial planting, both the planting technology and the sales channels have matured. The villagers have already had a bottom in the production and income of garlic. Therefore, at the beginning of the year, the cooperative said that garlic should be planted. More than 30 farmers in the village responded positively. The planting scale has been expanded to nearly 100 acres.
   Ma Aimin, the village director, said: "We have traditionally planted corn here, but the potential for increasing corn income is not large. The income of one mu is more than 1,000 yuan. Through the two years of garlic cultivation, the villagers have actually tasted the sweetness. The income of the mu is corn. Four or five times."
   It is understood that in the future, the garlic field in the new joint venture village will be planted with Suzi. Suzi planting is also based on the pattern of garlic planting, which is purchased by the cooperative, unified management, unified sales, and the lowest protection price. Suzi leaves can pick up 400 kilograms in an acre of land , 1 kilogram of leaves can sell 1 yuan, and Suzi produces 200 kilograms per mu . The lowest price is 7 yuan and 1 kilogram. In addition to the income of garlic, such an acre of land can have an income of at least 1,800 yuan. Farmers can increase their income, and of course the interplanting will be promoted.

A spectacle blind or spec blind, is a safety device used to isolate a section of line or piece of equipment when the line or equipment needs to be inspected or removed from service. It is different than a valve in that the blind is a permanent or long term isolation device.
A spectacle blind is machined from a single piece of metal that is cut to match the pipe size, fit between two pipe flanges and requires an additional Gasket when it is installed. Also, the bolts will need to be lengthened depending on what piping class and size blind is used. The thickness of the spectacle blind is specified based on the line pressure and pipe size.
The specification that determines the dimensions of a spectacle blinds is ASME B16.48 - Line Blanks. A line blank conforming to this standard will be marked in the following way:
B16
Nominal Pipe Size (NPS)
Nominal Pressure Class
Material
Manufacturer's Name
If RTJ, the ring number
One end of the blind will have an opening to allow flow through the pipe during operation and the other end is solid to block flow during maintenance
