摘要： A method for forming a plurality of composite parts via resin transfer molding in a single molding cycle. The method includes the steps of using a mold having first and second mold members that cooperate to house a plurality of shims and placing a plurality of preform workpiece into the mold cavity such that at least one of the shims is disposed between each of an adjacent pair of the preform workpieces. A liquid resin is then injected into the mold cavity and subsequently cured to thereby form a cured workpiece matrix that is composed of a plurality of semi-finished composite parts and at least one shim separating the plurality of semi-finished composite parts from one another.

摘要： A method of manufacturing a sacrificial limb for a deck plank provides a deck plank that is comprised of a wood replacement material. The deck plank has a tongue that is adapted to fit with a groove of an adjacent deck plank. A channel is cut in the tongue of the deck plank. The channel is adapted to induce the tongue to fracture when expansion of the wood replacement material causes sufficient pressure between the tongue and the groove of the adjacent deck plank. As a result, expansion and contraction of the deck plank material preferably does not cause the deck to buckle.
摘要翻译：制造用于甲板板的牺牲肢体的方法提供由木材替代材料组成的甲板板。甲板板具有适于与相邻甲板板的槽相配合的舌头。在甲板板的舌头上切割一个通道。当木材替代材料的膨胀在相邻的甲板板条的舌部和沟槽之间引起足够的压力时，该通道适于诱导舌头断裂。结果，甲板板材的膨胀和收缩优选不会导致甲板弯曲。

摘要： To make holes in ceramic green sheets that are needed to create feedthroughs, it is proposed to make the holes by using a gas that is under a higher pressure than atmospheric pressure and that is expelled in a pulsed manner from a pressure vessel and thereby acts on a principal surface of a ceramic green sheet, at at least one location at which a hole is to be made, in such a way that material is shot out of the ceramic green sheet at that location. This eliminates the disadvantages associated with the use of punches to punch holes.
摘要翻译：为了在形成馈通所需的陶瓷生片中形成孔，提出通过使用比大气压更高的压力的气体来制造孔，并且以脉冲方式从压力容器排出，从而作用于在要形成孔的至少一个位置处的陶瓷生片的主表面以使得材料在该位置从陶瓷生片中被喷射出来。这消除了与使用冲头冲孔相关的缺点。

摘要： A cutting mechanism for cutting fibers entrained within a viscous flow is herein disclosed. The present invention is typically part of a system for preparing fiber reinforced molding materials that comprises a viscous entrainment compounding device for compounding a continuous strand of reinforcing fiber with a molding material in a predetermined ratio. The entrained fibers are conveyed to the cutting mechanism which cuts the continuous strand of reinforcing fibers into predetermined lengths and conveys the fiber reinforced molding material to an output device. The cutting mechanism itself comprises a housing having a bore with an inlet and an outlet and a bed knife disposed therein. The bed knife has an inlet channel formed therethrough that is aligned with the gullets of a rotating cutter such that the gullets of the rotating cutter are rotated past the inlet channel of the bed knife in substantial alignment therewith. Fibers entrained within the molding material flow into the gullets of the rotating cutter and are cut to a predetermined length and then conveyed to an output device.
