Leakage horizontal

The use of multinozzle injection machines. In general, this type of machine has a horizontal reciprocating screw that feeds four injection nozzles each connected to a single cavity mold thus minimizing waste. However, one concern with this approach is the need to have the mold accurately lined up (the top and bottom surfaces of the mold will be in the vertical plane) to eliminate compound leakage at the nozzle/mold interface. 

A distillation system is to operate with a horizontal overhead condenser. Figure 6-19, and pressures are as marked. The estimated air leakage into the system is 7 Ibs/hr. The molecular weight of the product vapor going out the condenser into the ejector (at 80°F) is 53. The vapor pressure of the condensing vapors is 3 mm Hg abs at 80°F. 

The hot well is the sump where the barometric leg is sealed. It must be designed to give adequate cross-section below the seal leg and for upward and horizontal flow over a seal dam or weir. At sea level the hot well must be a minimum of 34.0 ft below the base of the barometric condenser. For safety to avoid air in-leakage, a value of 35-36 ft is used. For an altitude corresponding to a 26-in. Hg. barometer, the theoretical seal height is 29.5 ft actual practice still uses about 34 ft. 

Smoke dampers are used to prevent the spread of products of combustion within ventilation systems. They are usually activated by the fire alarm and detection system. Smoke dampers are specified on the leakage class, maximum pressure, maximum velocity, installation mode (horizontal or vertical) and degradation test temperature of the fire.

Leakage Test This test is mandatory for ophthalmic ointments, which evaluates the intactness of the ointment tube and its seal. Ten sealed containers are selected, and their exterior surfaces are cleaned.They are horizontally placed over absorbent blotting paper and maintained at 60 3 °C for 8 h. The test passes if leakage is not observed from any tube. If leakage is observed, the test is repeated with an additional 20 tubes. The test passes if not more than 1 tube shows leakage out of 30 tubes [15]. 

The Tiselius Apparatus.—The U-tube portion of the apparatus, shown in section (I) and in plan (II) in Fig. 130, is in several parts which can be slid horizontally across one another along the planes oa, 66 and cc the surfaces between the sections are suitably lubricated in order to facilitate the sliding and to prevent leakage of liquid. The channel running through the center of the apparatus, shown by the thicker lines,...
