Abstract: A wire positioning adapter for dressing wires from a multi-conductor cable to transverse terminal locations is disclosed. The adapter is used with a standard semi-automatic insertion apparatus which simultaneously attaches a pair of conductors to oppositely facing terminals. The adapter moves along a linear path with respect to the connector. Wires are laced across a wire positioning surface between the cable end and the terminals. The wires are allowed to longitudinally slip across this surface during movement of the adapter.

Abstract: A hydraulic extractor and its use in removing damaged draft gear which are wedged in railway cars. It consists of a length of pressure resistant hose folded at its center to lie flat upon itself when empty, and having connections at both ends for receiving hydraulic fluid under pressure. Also included is an arrangement for feeding the hose into the restricted space above the draft yoke and below the draft sill. That arrangement comprises a pair of strips of sheet metal of a width generally the same as that of the flat hose, and means connecting the strips together at one end. The hose is placed between the strips, with the fold near the connecting means. A rudimentary winch is provided for connection by a cable to the metal strips where they are connected. In use, the cable is fed through the space to be expanded, and connected to the winch, and the hose in its protective metal strips is winched into the desired location.

Abstract: Gold alloy bumps are built up upon conductive pads formed upon electronic chips. The bumps are thereafter aligned with conductive portions of a generally larger substrate to which the chips are to be electrically connected. The bumps are produced by either vacuum evaporating or plating metallic layers over the conductive chip pad areas wherein certain layers within the bumps are formed of magnetic metals such as cobalt or nickel cobalt alloys. Metallic layers of gold and alloying metal are evaporated or plated over the deposited magnetic metals to complete the formation of the bumps. The chips are thereafter subjected to a sufficient amount of heat to cause the bumps to flow, thereby to form a reliable electrical connection between the chips and the substrate. The magnetic materials formed within the bumps result in ease of transporting and manipulating the chips for further processing by means of magnetic plates or other pickup devices.

Abstract: Electrical wire conductors which project from two insulated cable end portions are received in tubular electrical connectors electrostatically precoated with electrical insulating material. Each precoated connector end portion respectively abuts and is sealed in engagement with insulation on an associated cable end portion. The precoated connectors are crimped into gripping engagement with the wire conductors therein to form a basic electrical splice. A tubular inner melt liner and a tubular outer sleeve of thermoplastic electrical insulating material are arranged in generally coaxially surrounding relation with the basic splice. Heat is applied to substantially simultaneously melt the inner liner and shrink the outer sleeve to encapsulate the basic splice.

After the sheet is wrapped about the pipe body its free edges are fastened together so that the device can be removed.

Abstract: Method of passing an uninsulated, relatively rigid, conductor through an opening in a non-conductive housing wall.

Abstract: An apparatus for attaching slotted plate terminals or the like to individual wires such as the wires of a stator coil in an induction motor is disclosed. A rotatable arbor positions the stator in alignment with an insertion track and ram.

Abstract: A method of lubricating a metal billet during an extrusion process where at least two lubrication systems are used. Each of the lubrication systems has a different viscosity and the systems can be of the same material or two different material compositions. A solid-lubrication system immediately adjacent to the billet functions primarily as a die lubricant while a liquid-lubrication system immediately adjacent the container is pressurized by the advance of a sealed ram in contact with the billet. The liquid lubrication system forms a thin film of pressurized liquid lubricant adjacent the container wall and substantially reduces or virtually eliminates friction thereupon during extrusion of the billet under hydrostatic or quasi-hydrostatic conditions.

The iron core may be enclosed in a leak-proof jacket for supplying a coolant to the core for cooling thereof.

Abstract: A method for mounting socket contacts to the leads of electronic component packages having a dual-in-line configuration, and for one-step mounting of the pre-socketed packages to dual-in-line arrays of holes in a panel board. Dual-in-line packages (DIP) are fed to a processor where a plurality of socket contacts are separated into two parallel spaced rows and the leads of the DIP are inserted into the sockets.

The interfacial connections are then completed by dip soldering or by welding. Alternatively, the second circuit applied to the substrate may be in the form of a preformed circuit on a flexible substrate.

Abstract: Manufacturing of a soft metal sheath formed of aluminum or copper, for example, is improved by suitably selecting the apparatus composing the shaping means employed therein and arranging the capstan and the sinking die in a novel manner.
