Many glass plates used on the desktop are characterized by high density, poor heat absorption, and strong reflection. When people work at desks, their mouths and noses are generally closer to the glass plate, and exhaled carbon dioxide and other exhaust gases pass through the glass table. The board bounced back and most of them were inhaled into their bodies, causing the brain to have insufficient oxygen supply, causing symptoms such as dizziness, nausea, and indigestion. In addition, the temperature on the glass platen is usually about 10 degrees Celsius lower than the normal temperature in the room. Especially in the summer, people's elbows are exposed, and they are directly pressed on the glass platen, so that the sweat pores are occluded, so that sweat is not easy. discharge. In addition, the color of the picture of the glass platen pad stimulates human eyes through the reflection of the glass plate, thereby affecting the human vision, the eyes are easily fatigued, and the human energy is also easily dispersed.
Therefore, try not to spread the glass platen on the desktop. If you really need to use, first let the room more ventilated, and under the glass platen underlay some dark green matte velvet cloth and the like. When working at the desk, try to keep your mouth at least 20 cm away from the glass platen.

A solder ring fitting, also known by the trademarked name Yorkshire fitting,is a pre-soldered capillary connector for joining copper pipes used in plumbing.While less convenient than compression joints and less reliable than flux solder joints, they are useful when fitting in confined spaces and where single handed fitting is required.
To obtain perfect joins, the inside of the fitting and the outside of the copper pipe are cleaned using coarse steel wool, flux paste is applied, the pipe is inserted into the fitting and heat applied from a portable propane torch until a ring of solder shows at the edges of the fitting. To obtain a durable joint, water must not be poured on the solder joint to cool it. Yorkshire fittings are now made with lead-free solder.The fittings come in a great variety of configurations, such as Tee-pieces, straight couplers, elbows or bends, reducers (to join pipes of different diameters), stop-ends, and there are versions with screw threads (male or female) at one end to fit taps and galvanized iron pipes.Valves such as stoptaps & gate valves are also available in solder ring configuration.
