Patent number: 6490501Abstract: A monitoring and control system for use in curing composite materials includes a model for a workpiece being cured. The model calculates current internal states of the workpiece and predicts, based upon past and current states of the workpiece, future states of the cure process. These future states are represented as virtual inputs to the controller, which controls operation of the cure process based upon both real and virtual inputs. Cure rates are affected by both external temperatures and internal heat generated by the curing process itself. The internally generated heat is considered by the model when calculating current states and predicting future states. By projecting the cure state into the future, problems caused by high cure rates can be avoided. In addition, pressure can be optimally controlled in response to estimated internal material state.Type: GrantFiled: October 6, 1999Date of Patent: December 3, 2002Assignee: Bell Helicopter Textron Inc.Inventor: Arven H.

Patent number: 4973370Abstract: Braided fine wire cable is prepared for termination by electrical terminals by a coating of dielectric material such as curable varnish which coats and embeds the myriad of fine wires. The coating upon hardening imparts structural integrity to the otherwise very flexible cable, enabling handling. The coating also retains the wire portions many of which may be severed during application of electrical terminals thereto to obtain electrical connection of portions of the terminals with ends or surfaces of many of the wires, thus preventing disintegration of the cable's termination region when the terminals are applied. The hardened coating also enables the cable region to be shaped and formed to some extent, even including cutting or notching the cable, to adapt the cable region to the structure of the terminals, enabling use of existing terminals used for terminating solid flat conductor cable, for example.Type: GrantFiled: December 21, 1989Date of Patent: November 27, 1990Assignee: AMP IncorporatedInventor: Earl R.

Patent number: 4961713Abstract: A dual molded connector and a dual molding process for fabricating a insulative housing having a relatively rigid portion and a relatively more flexible sealing portion is disclosed. The relatively rigid portion is first formed in a mold. Elastomeric material can then be injected after shifting portions of the mold define voids adjacent opposite faces of the molded rigid housing. An internal gate between opposite surfaces of the housing permits sealing material to flow into the void on opposite faces of the housing. Thus, only an external single gate for the injection of sealing material is necessary.Type: GrantFiled: October 22, 1987Date of Patent: October 9, 1990Assignee: AMP IncorporatedInventors: Dennis C.

Patent number: 4941850Abstract: The present invention provides a connector having a seamless tubular metallic shell which not only provides proper RFI/EMC shielding but also is constructed in such a way as to prevent ingress of moulding material into the spaces between contacts of the connector. This is achieved by forming one end of a seamless tube of ferromagnetic material (which is initially of substantially uniform cross-sectional area) such that is collapsed on to itself and a cable connected to the connector whereby to tightly seal the send of the tube on to the cable to prevent ingress of moulding material subsequently applied to the exterior of the shell. In the case of a cable providing a braid or foil shielding element, this process simultaneously provides an electrical bond between the shell and a portion of the shielding element of the cable exposed by removing a portion of the outer insulation covering of the cable.Type: GrantFiled: January 25, 1989Date of Patent: July 17, 1990Inventors: Malcolm D.
