TL;DR: In this paper, a plate for directing the flow of fluids which is shaped so as to provide contact points capable of spacing it from and supporting it against similar plates, is also provided with further contact points so that by suitable arrangement of the plates, the spacing there between can be varied.
Abstract: A plate for directing the flow of fluids which is shaped so as to provide contact points capable of spacing it from and supporting it against similar plates, is also provided with further contact points so that by suitable arrangement of the plates, the spacing therebetween can be varied. The basic contact points on the standard plate are provided by a herring-bone pattern of V-shaped hill and valley corrugations and, preferably, the further contact points are formed by stamping the plate so that portions of the hill structure of the corrugations are provided with reversed hill and valley formations, although they may be formed by studs or projections attached to the plate.

02 Sep 1969TL;DR: In this article, the authors propose a method of associating a multiplicity of contacts in a configurable environment, such as a Strip Connector, by stamping or milling the MULTIPLE CONTACT CONFIGRUATION from a BLANK of CONTACT MATERIAL.
Abstract: A METHOD OF ASSEMBLING A PLURALITY OF CONTACTS IN A CONFIGURATON SUCH AS A STRIP CONNECTOR. THE STEPS OF THE METHOD CALL FOR STAMPING OR MILLING THE MULTIPLE CONTACT CONFIGRUATION FROM A BLANK OF CONTACT MATERIAL, MOLDING A CONNECTOR HOUSING ABOUT THE CONTACTS WHILE THEY ARE STILL ATTACHED TO THE BODY OF CONTACT MATERIAL AND THEREAFTER SHEARING THE FINISHED CONNECTOR AWAY FROM THE BODY OF CONTACT MATERIAL. IN ONE VARIATION THE MILLED CONTACTS ARE PINS WHICH ARE INSERTED INTO TUBULAR CONNECTORS OR SOCKETS WHICH ARE THEN SECURED TO THE PINS BY MEANS OF MECHANICAL CRIMPING. THEREAFTER THE MOLDING STEP IS UNDERTAKEN TO FORM A CONNECTOR HOUSING ABOUT THE PLURALITY OF CRIMPED PIN-SOCKET COMBINATIONS. THE FINISHED CONNECTOR IS THEN SHEARED FROM THE BODY OF CONTACT MATERIAL AS BEFORE.

TL;DR: In this paper, a porous metal element, e.g., porous bronze, such as a mass of sintered tin-coated copper spheres, filled with a solder base material, is used as an element in a soldering device for delivering solder to the place where needed.
Abstract: A porous metal element, e.g., porous bronze, such as a mass of sintered tin-coated copper spheres, filled with a solder base material, is used as an element in a soldering device for delivering solder to the place where needed. The porous material is usually about 40-50 percent by volume, or more, interconnected voids and the voids are preferably completely filled with the solder base material to the exclusion of air. The soldering element is maintained filled with solder by surface tension while the solder is in molten condition during use of the device. The soldering element may be in the form of a tip on a soldering gun or soldering iron, or in the form of a stamping plate for stamping printed circuits or any other convenient form.

Abstract: A method and apparatus for dry engraving sheets of material wherein the method includes holding a sheet fixed in a first position while die stamping a layer of decorative foil thereon to present a specific design, shifting the sheet to a second position in alignment with an embossing die while retaining control over the sheet during shifting thereof, and holding the sheet fixed in the second position while embossing the sheet to form raised areas thereon underlying the foil design impression in exact registration therewith to simulate an engraved design. The apparatus includes a pair of side-by-side, oppositely reciprocable shuttle bars each having a series of vacuum ports therein which communicate with a vacuum source in timed relationship to the reciprocation of the respective bars. The shuttle bars thereby alternately shift new sheets into position for processing and cooperate to simultaneously hold fixed one sheet for foil design stamping thereof and another sheet for strategic area embossing thereof.

The poles each have projections 6, 7 to define a narrow mouth 12 and to hold a key 13 in position. In an alternative embodiment the commutator pole 5 is slotted to receive the end of the key and the projections omitted, Fig. 3 (not shown). The punch 15 for stamping the slots comprises two main portions 15a which define the commutator poles and one edge of each adjacent main pole.

TL;DR: In this article, the method of forming conductor pattern stampings for electric motor armatures is described, where metal blanks are indexed and punched at a succession of stamping positions to remove metal between adjacent conductor segments.
Abstract: The method of, and punching press for, forming conductor pattern stampings for electric motor armatures. Metal blanks are clamped to a drive shaft by a universal clamp which eliminates eccentricities in rotation. The blanks are indexed and punched at a succession of stamping positions to remove metal between adjacent conductor segments. Alignment holes are punched into the blank at selected stamping positions to establish a flip line used in subsequent assembly operations. The motor armatures are assembled using at least two identical stampings oriented by the alignment holes and the flip lines, bonding the aligned stampings to a dielectric disc, and welding aligned tabs of the stampings to form the armature interconnections.
