Abstract: In one embodiment, the pack is torsionally flexible. Pack of laminations comprises laminations which are connected one to another by only a single connection. The single connection is provided by a projection which projects into a depression. The projection has a height which is greater than 50% of the thickness of the lamination and the depression has a depth which is greater than 50% of the thickness of the lamination. The depression and projection are produced by a projection punch which cooperates with a die. The die has a lip which is either radiused (r) or conical (C) and the punch causes the metal of the lamination to be extruded past the lip into the die while the depression is being formed. The radiused or conical lip allows the height of the projection and the depth of the depression to be greater than the normal 50% shear stress fracture depth/height.

Abstract: In a process for repairing electronic device packages, the problem of removing solder remnants on substrate bonding pads is solved by, first etching a pattern in silicon and metallizing the pattern to make a silicon wick. The solder remnants on the bonding pads are melted, and the etched pattern of the silicon wick is brought into contact with the remnants to remove them by capillary action. It is often convenient to heat the silicon wick so that solder remnants melt when the wick is brought into contact with them.

Abstract: A discrete track thin film metal alloy or metal oxide magnetic recording disk is fabricated by forming a thin film of magnetic material on a substrate, patterning the magnetic film with a chemically etchable support layer and a high resolution photoresist layer, removing portions of the magnetic film and refilling with nonmagnetic material to form concentric nonmagnetic guard bands, and then applying a top layer of additional nonmagnetic material as a passivating and protective disk overcoat after removal of the remaining support layer and photoresist. The exposed photoresist and portions of the chemically etchable support layer beneath the side walls of the patterned photoresist defining the edges of the magnetic tracks are removed in a photoresist developer which also creates undercuts in the support layer beneath the side walls. The undercuts prevent "fences" and provide smooth interfaces between the magnetic tracks and the nonmagnetic guard bands.

Abstract: A flexible character-indentable plastics embossing tape (11) is backed by and bonded to a lead strip not more than 0.025 inches (i.e. approximately 0.65 millimeters) thick, to form a tape suitable for identifying radiographs. The lead strip (13) is itself backed by a relatively thin and flimsy plastics or fabric strip (15) which, when removed, allows the lead (and hence the lead-plastic tape as a whole) to be pressure-bonded to the surface to be radiographed.A conventional tape-embossing gun is used to indent the desired characters in succession, and in order, into the lead-backed tape, without necessarily severing the lead; and then the backing strip (15) is peeled away to expose the layer (14) of adhesive which pressure-bonds the indented tape to the object to be radiographed.X-rays incident on the embossed tape will cause the raised characters (a) to show up dark on the subsequently-developed film, while the raised side areas (b) will show up white. Each character will thus stand out on the developed film.

Abstract: A new embedded-lens retroreflective sheeting which exhibits superior properties, including superior angularity, and which is made by a new method of manufacture involving lamination techniques. Microspheres are embedded into a first polymeric layer to less than one-half the average diameter of the microspheres, and a pre-formed spacing film is laminated to the microsphere covered surface of the first layer so as to obtain conformation of the spacing film in a substantially constant thickness over a useful portion of the back surface of the microspheres.

Abstract: A superimposed foil embossing method using both opaque foils and transparent pastel foils. A first flat stamping die transfers a first foil, which can be either an opaque foil or a transparent foil, from a first carrier ribbon to the paper stock. The first foil is transferred by the application of heat and pressure. A second flat stamping die transfers a transparent foil from a second carrier ribbon to the stock so that it is superimposed over the first foil. Since each foil is only transferred from the ribbon to the paper in the areas where the die touches the paper, the pastel foil can be applied directly to the paper and also superimposed over areas of the first foil. Thus, if the first foil is an opaque foil, the color combinations possible include the paper stock color, the first foil color, the altered color of the paper having the transparent foil thereon, and the altered color of the first foil with the transparent pastel foil embossed thereon.

Abstract: This invention is concerned with high density compacted and sintered polymer articles which previously could not be made entirely non-porous to liquid. It was inevitable, in an article with different parts, that frictional considerations in pressing one part would materially differ from those of another with the practical result that uniformity of density, throughout the article, could never be achieved. Fortuitously, for purposes of making various different parts of an article void free, the density values for each part need not be substantially all the same, but instead need only be raised above a predetermined threshold value.An object of this invention is the preparation of physically dense objects of sintered polymer with multiple parts, such as with abruptly varying cross section, which are uniformly void-free throughout, and of everywhere "theoretical" (reguline) density.

Further in accordance with the invention such substrate is made by first forming and firing a ceramic plate of alumina or beryllia ceramic to provide the base layer and then applying and firing a coating of fine grain alumina or beryllia, as the case may be, on the plate to provide the upper layer.
