摘要:
A floor drain arranged to be positioned in a depressed manner in a floor, comprising a drain member (3) provided with an opening in its upper part for receiving a drain grating member (6), which is arranged loosely on at least one underlying support surface of the drain member (3). The drain grating member (6) has a surface directed upwardly and located, at least in one area in the vicinity of the peripheral edge of the drain grating member (6), below or at essentially the same level as the floor surface of said floor at least in the vicinity of the drain member (3). The drain member (3) comprises an upwardly projecting portion (4) located centrally and comprising said support surface (10) for the drain grating member (6).
摘要:
A method and system for coating a glass contacting surface with a thermal barrier and lubricious coating. The system uses a novel exterior surface mixing tip device (1) wherein oxygen is supplied through a predetermined portion of one supply line (3), and a predetermined gas is supplied through a predetermined portion of another supply line (4) enveloping the first predetermined portion. Each supply line consist of a regulator (7,8), throttle valve (9,10), flow meter (11, 12), check valve (13, 14), control valve (15, 16), three-way valve (17,18) and back flash valve (19, 20). Oxygen and gas do not mix until they reach the tip (6) of the mixing tip device (1).
摘要:
Methods of heating glass contacting surfaces, comprising heating the glass contacting surfaces to a predetermined operating temperature by combustion of a hydrocarbon fuel gas mixture which includes 90 % by volume of MAPP gas and 10 percent by volume of propane. Another method blends the MAPP with air and/or natural gas. A novel hydrocarbon fuel gas mixture which includes 90 % by volume of MAPP gas and 10 % by volume of propane.
