Abstract: A single piece electrical connector having a housing with a mating face, a wire receiving face, and housing side walls. Terminal receiving cavities extend from the mating face to the wire receiving face. The terminal receiving cavities have cavity side walls. Resilient securing arms are provided in the terminal receiving cavities. The resilient securing arms have fixed portions which extend from and are integrally attached to base members which extend from and are integrally attached to the cavity side walls of the terminal receiving cavities. The resilient securing arms are made from the same material and in the same manufacturing process that forms the housing. The fixed ends are spaced from the cavity side walls by gaps. The gaps between the resilient securing arms and the cavity side walls facilitate the cleaning or removal of excess material formed during the manufacturing process of the electrical connector.

Abstract: An electrical connector includes a shell and a coupling ring. The shell has contact receiving passages and an outer wall with a coupling ring retaining projection. The coupling ring is integrally mounted on the shell. The coupling ring is movable between a first position and a second position. A spring is integrally positioned on the coupling ring. The spring is provided in a stressed position when the coupling ring is moved to the second position. Openings are provided in the coupling ring; the openings being positioned proximate the spring. The opening are dimensioned to allow the removal of residual material produced during the manufacture of the electrical connector.

Abstract: An electrical connector matable to and unmatable from a separable mating electrical connector includes a housing having a terminal channel and a secondary channel. The electrical connector also includes a female terminal received in the terminal channel. The female terminal is matable with and unmatable from a mating male terminal of the mating electrical connector. An arc suppression element is received in the secondary channel. The arc suppression element configured to electrically couple between the female terminal and the male terminal immediately after the female terminal is disengaged from the male terminal, the arc suppression element providing a bypass between the female terminal and the male terminal so that arcing does not occur when the female terminal is disconnected from the male terminal of the mating electrical connector.

Abstract: An additive manufacturing apparatus and method having a flexible delivery system for delivering pellets from a stationary material receiving area to a movable discharge pump. The flexible delivery system includes a flexible tube, an air compressor and an air-material separator. The air compressor is connected to an end of the flexible tube to direct controlled compressed air through the flexible tube. The air-material separator has a material receiving chamber which receives the pellets from the flexible tube through a material receiving opening. The material receiving chamber extends to a nozzle feeding opening and a nozzle feeding tube. The material receiving chamber has an exhaust opening through which the compressed air is vented out of the air-material separator.

Abstract: A heating device and method for providing temperature control in an additive manufacturing processes. The heating device is positioned circumferentially about a print head and proximate a top layer of a printed object. An area of the top layer of the printed object is heated by directing energy from the heating device to the top layer as material is deposited from the print head onto the printed object. The directed energy applied to the printed object reduces distortion of the printed object caused by temperature gradients and improves the layer-to-layer bonding of the printed object.

Abstract: The present disclosure provides optical fiber preforms formed from core canes having large core-clad ratio, intermediate core-cladding assemblies, and methods for making the preforms and core cladding assemblies. The preforms are made from core canes having a contoured end surface. The contoured end surface(s) include a depression that acts to reduce the stress that develops at the junction of the end surface of the core cane with a soot cladding monolith arising from differences in the coefficient of thermal expansions of the core can and soot cladding monolith. The contoured end surface(s) leads to preforms having low defect concentration and low probability of failure during fiber draw.

Abstract: A connector and a method of retaining a contact in a housing. The method includes: inserting the contact into a contact receiving cavity of the housing; applying extruded material in layers into the contact receiving cavity with a precision controlled nozzle; filling voids in the contact receiving cavity layer by layer until the contact receiving cavity is filled; and cooling or curing the extruded material, allowing the extruded material to bond with a wall of the contact receiving cavity. The contact is securely maintained in the contact receiving cavity of the housing by the extruded material. The connector having a contact positioned in a contact receiving cavity of a housing. Extruded material is positioned in the contact receiving cavity. The extruded material is bond to walls of the contact receiving cavity, wherein the extruded material securely maintains the contact in the contact receiving cavity of the housing.

Abstract: A method of forming an optical fiber includes the steps of forming a soot blank of a silica-based cladding material, wherein the soot blank has a top surface and a bulk density of between 0.8 g/cm2 and 1.6 g/cm3. At least one hole is drilled in the top surface of the soot blank. At least one core cane member is positioned in the at least one hole. The soot blank and at least one soot core cane member are consolidated to form a consolidated preform. The consolidated preform is drawn into an optical fiber.
