Abstract: The invention describes a method for generating a shell mold for castings, in which the shell mold is described from a multiplicity of finite volume elements and/or surface elements which are connected to one another via node points and which together form a mesh points for describing the surface of the shell mold. First, the real surface geometry of the casting is recorded and generated in the form of a coherent base mesh. Then, an approximated simulation of the real surface geometry is complied by means of finite volume elements and/or surface elements. This is followed by the determination of in each case one shell node point for each node point contained in the base mesh and the generation of shell vectors and a new surface element which is positioned above each shell node point and in each case defines a volume element which, together with all the other newly formed volume elements, leads to a first layer of the shell mold.

Abstract: An electrical connector is provided for terminating a flat flexible circuit which has at least one pin-receiving hole therein. The connector includes a dielectric housing. At least one conductive terminal is mounted on the housing and includes a projecting pin portion exposed on the housing. A circuit carrier is provided for receiving the flat flexible circuit. The carrier is mountable on the housing in a position for aligning the pin-receiving hole in the circuit with the pin portion of the terminal.

Abstract: The invention generally relates to a camming system for mating and unmating a pair of connectors having a housing mounting a plurality of terminals mateable with the terminals of the other connector and a camming system for moving the housings towards and away from each other along a mating axis. A lock slide member is mounted on one of the housings and slidably movable along a path transverse to the mating axis. The lock slide member is including at least one cam track extending oblique to the mating axis and the other housing has at least one cam follower projecting into the cam track for mating the connectors in response to sliding movement of the lock slide member. According to the invention, a lever means is pivotally mounted on the lock slide member, and an arcuated slot is disposed in the lever means slidably engaging a projection formed in one of the housings.
