摘要： A compression molding operation is controlled by applying a press force to a mold having a cavity charged with molding compound. The separation of the mold halves is measured at each corner thereof by linear variable differential transformers. Hydraulic cylinders operating on the press ram generally in the area of each corner of the molds are individually controlled to locally vary the press force on the molds to maintain mold parallelism as determined by the LVDT's to control the velocity of press closing also as measured by the LVDT's according to a preprogrammed velocity profile, and further to control the amount of press force applied to the molds according to a preprogrammed value during curing of the molding compound.

摘要： A low-cost, easily fabricated bumper structure for the alleviation of repeated, low-magnitude impact shocks on a vehicle. The bumpers utilize structural elements of fiberglass or similar lightweight, high-strength materials to absorb energy of impact. The fiberglass elements of the subject bumper are fabricated by relatively inexpensive manufacturing processes, such as molding, pulltruding or extruding.

摘要： A mass of alloy material is deposited on a valve seat and is heated to alloying temperature by a laser beam which sweeps around the valve seat thereby alloying the valve seat. While the alloyed material is still at a high temperature, the forming tool is pressed against the valve seat to shape the valve seat to a configuration which requires little or no grinding.

摘要： In accordance with a preferred embodiment of this invention, a precessing bottom pour stopper is used to accurately and precisely control the flow of molten metal through the tap hole which is located in the bottom of a metallurgical vessel. The precessional movement of the stopper, as it moves into and/or out of sealing engagement with the tap hole, removes any debris which may be lodged between the sealing surfaces and thereby ensures a tight seal over a prolonged period of operation.
摘要翻译：根据本发明的一个优选实施例，使用前进底部浇注塞来精确地和精确地控制熔融金属通过位于冶金容器底部的抽头孔的流动。当止动器移动进入和/或脱离与排出孔的密封接合时，止动件的进动运动消除了可能被封装在密封表面之间的任何碎屑，从而确保在长时间的操作中的紧密密封。
