Abstract: A ported mold having a peripheral lip is positioned in a backing mold having mold pins centrally disposed in the ports and having recesses surrounding the mold pins. The recesses are filled when a layer of flowable plastics material is placed in the ported mold. The lip of a filter housing is positioned in the ported mold and, with the curing of the plastics material, the ported mold becomes a part of the filter and ported abutments forming an inlet and an outlet for the filter are provided. The mold pins may be of different lengths so that the ports may be open, or sealed by a thin layer of plastics material.

Abstract translation: 具有外围唇缘的移植模具定位在背模中，其具有中心地设置在端口中的模具销，并且具有围绕模具销的凹部。 当将一层可流动的塑料材料放置在移动的模具中时，凹槽被填充。 过滤器壳体的唇缘定位在移植的模具中，并且随着塑料材料的固化，提供了移植的模具成为过滤器的一部分并且形成了用于过滤器的入口和出口的移动的基台。 模具销可以具有不同的长度，使得端口可以是敞开的，或者是被薄的塑料材料密封。

Abstract: A WATER SEPARATOR FOR A DIESEL FUEL SUPPLY SYSTEM PROVIDES A PLENUM CHAMBER HOUSING A WATER SEPARATOR BARRIER MADE OF RIBBED-KNIT POROUS CLOTH IN THE FORM OF A CYLINDRICAL SOCK HAVING A CLOSED END. THE OPEN END OF THE SOCK IS SEALED AROUND THE INLET PASSAGE OF THE SEPARATOR SO THAT FLOW MAINTAINS THE SOCK INFLATED FOR FLOW THROUGH THE ENTIRE POROUS SURFACE AREA OF THE SOCK. THE PORES OF THE SOCK ARE SMALLER, WHEN RELAXED, THAN THE WATER DROPLETS TO BE SEPARATED AND THE SOCK IS MADE OF NYLON WHICH IS NOT WETTABLE BY WATER. THE PORES OF THE SOCK ARE EXPANDABLE AS REQUIRED TO ACCOMMODATE VARYING FLOW RATES WITH A MINIMUM CHANGE IN PRESSURE DIFFERENTIAL ACROSS THE SOCK AND TO PERMIT THE PASSAGE OF LARGE WAX PARTICLES UNDER LOW TEMPERATURE OPERATING CONDITIONS TO PREVENT CLOGGING.
