Abstract: A reciprocating fluid pump includes a drive section and a pump section. The drive section has a pair of coils which may be energized to cause displacement of a reciprocating assembly. Each coil is a reluctance gap arrangement in which a magnetic circuit is interrupted by a gap towards which an armature of the reciprocating assembly is drawn when energizing current is applied to the coil. The reciprocating assembly includes an element which is extended into and retracted from a pump chamber during its reciprocating motion, causing fluid to be drawn into and expelled from the pump chamber. The pump is particularly well suited for use in cyclic pumping applications, such as internal combustion engine fuel injection. Cycle times in such applications may be reduced by appropriate control of the current waveforms applied to the coils.

Abstract: Disclosed herein is a resin transfer molding apparatus including a female mold member having a rigid surface including a main surface portion, and a recessed surface portion extending inwardly from and bordered by the main portion to define a recessed area, and a male mold member including a structure which is adapted to be drawn into close association with the rigid surface of the female mold member in response to the application of vacuum therebetween and which includes a member which is at least partially flexible and which includes an inner surface located, during the application of vacuum, in relatively adjacent opposing relation to the main surface portion of the female mold member and in relatively spaced relation to the recessed surface portion, and a segment which is relatively rigid, which has a shape conforming to the recessed area, which is fixedly bonded to the inside surface of the member, and which is located, during the application of vacuum, in relatively adjacent opposing relation to the rec
