Abstract: A magnetic head is manufactured by the steps of accommodating a core chip blank into an elongated hole provided in a slider blank, joining the core chip blank and the slider blank together with glass and then grinding the surface to form a surface which makes sliding-contact with a recording medium. Glass for joining the core chip blank and the slider blank together is obtained by melting a glass rod mounted in a predetermined position on the slider blank. In order to prevent the core chip from being positionally moved by surface tension of the molten glass when the glass rod is melted, the edges of the elongated hole are partially provided with protrusions for positioning the glass rod so as to prevent surface tension of the molten glass from positionally moving the core chip.

Abstract: One or more panels define a support for an image layer and a relatively dark layer. Holes extend through the panel and the layer. The holes allow viewing through the panels in one direction without seeing the image, yet the image can be viewed by looking at the panel assembly from the opposite direction. Thus, the image is suitable as an advertising medium as applied to the transparent windows of buildings, vehicles and the like. A person sitting in a building or in a vehicle cannot see the image on a window by looking outwardly through the window. Looking in the opposite direction, from outside to inside the vehicle, a person will see the image through the assembly of panels.

Abstract: A sheet material which includes an apertured top layer formed of a non-absorbant, thermally non-conductive thermoplastic material, a non-woven layer having a first portion formed of a mixture of moisture-wicking and moisture-absorbent fibers affixed to the top layer, and, optionally, a second portion including fibers which are non-adsorbent and non-absorbent, and, in various embodiments, a barrier layer and/or cushioning layer forming a laminate in which the nonwoven layer is sandwiched between the top layer and such other layers. The chemical formulation of the top layer of thermoplastic material can be varied to alter its coefficient of friction or degree of slip resistance depending upon the requirements of a particular application.

Abstract: The perceived softness of embossed tissue can be increased greatly while avoiding nesting when a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike bosses with deeper more sharply defined signature bosses. The stitchlike bosses can be rounded and arranged in wavy flowing intersecting lines. The signature bosses can be arranged in regions framed by the intersecting wavy flowing lines.

Abstract: Unusually strong and highly perforated plates are formed by pressurized filtration of a suspension of chopped ceramic fibers in an aqueous dispersion of colloidal alumina or colloidal silica through a mold having a perforated filter base and a pin support base having pins that extend through and beyond the perforations of the filter base. Pressurized filtration is preferably conducted by applying vacuum on the down stream side of the mold. When the layer of chopped fibers deposited on the perforated filter base has the desired thickness, filtration is stopped. The perforated filter base and pin support base are moved apart to retract the pins from contact with the perforated layer of chopped fibers which is transferred to a drier operating at a temperature not exceeding 650.degree. F., for conversion into a strong perforated plate.

Abstract: The invention is directed to a layered fabric material that is breathable and has resistance to fluid penetration. The fabric has a lightweight, breathable outer layer and a layer of non-woven material. The non-woven material is breathable and fluid resistant. The fabric also includes a thermoplastic film having a plurality of perforations. The perforations form capillaries that extend from a surface of said film. The capillaries are disposed at an angle from about 5.degree. to about 60.degree. with respect to the surface of said film. The capillaries formed by the perforations allow the film layer to be breathable while resisting direct flow of liquid through the film.

Abstract: A perforated sheet is diffusion bonded to a thin solid sheet. Each of the perforations of the perforated sheet is tapered, having a maximum diameter at the surface that is not bonded to the thin sheet and a smaller diameter at the surface that is bonded to the thin sheet. The bonded perforated sheet and thin sheet are included with other solid metallic sheets in a forming pack to be superplastically deformed into a structure. The bonded perforated sheet and thin sheet are placed on the top of the forming pack so that the thin sheet will face outwards after the structure is formed. After the superplastic deformation process is completed, the thin sheet is removed by machining to expose the perforated sheet and provide a structure for controlling laminar flow over the perforated sheet. The exposed surface of the perforated sheet includes the smaller diameter of each tapered perforation, while the inner-facing or blind surface of the sheet includes the maximum diameter.

The laminate comprises a polymeric carrier film and a permeation retardant coating applied to the carrier film. The carrier film welds to the container material to form an integral composite structure. The container may be produced by a method wherein a heated polymeric material is extruded within a mold. Laminate is dispensed adjacent hot polymeric material. The hot polymeric material softens the polymeric film carrier causing the two to weld together.
