Abstract: An air filter unit of the pleated media, high efficiency type wherein the media pleat edges are sealed to the supporting frame to prevent bypass of air with a ceramic adhesive and fibrous ceramic mat which allows the unit to be exposed to high temperatures (e.g., up to 2000.degree. F.) without danger of seal breakdown. While in the form of a slurry the adhesive is applied, for example, with a trowel to the zig-zag pleated edges of the media which, together with corrugated spacers, forms the filter core. The latter is then surrounded on four sides by the compressible mat of fibrous ceramic material and inserted in a box-like support frame with the slurry filling the space between the pleated edges of the media and the fibrous mat.

Abstract: A flexible, self-tightening mechanical splice between sections of cable or other elongated sections comprises an elongated braided wire sleeve receiving end portions of the elongated sections, and wire clamps securing the ends of the sleeve in circumferential grooves on two-piece grommets mounted on the elongated sections. The mechanical splice may be employed in conjunction with an electrical splice in electrical cable, such as armored electrical cable of the type used to support submergible pumping units in wells, for preventing application of tension to the electrical splice proper. An automobile jack of known construction is modified to provide a tool for forming the wire clamps.

Abstract: Methods of making feminine hygienic pads from non-layered and layered material by use of folding, pressure molding and various methods of bonding to create a long geometric form with an anterior leading panel of narrow thickness and a thicker posterior underpanel of a wider thickness. The folded panels may be bonded by either a suitable adhesive, crimping, heat, pressure or ultrasonic means leaving an anterior portion with a leading anterior edge and a larger posterior portion. A filler may be inserted between the folds of the material prior to bonding. Thereafter, the long geometric form is multiple cut transversely providing pads about two inches long. These pads are used for insertion into the female interlabial space. The geometric configuration of the pads facilitates insertion of the pad via the anterior leading edge into the interlabial space and has improved retention within such space.

Abstract: Identification plates are produced by applying retroreflective material upon a male die member and subsequently pressing a plate blank over the retroreflective material to adhere the material to the blank. The blank is then lifted from the male die member and the retroreflective material, in the form of characters to be formed upon the identification plate, has pressure applied thereto to remove air bubbles. The blank is then replaced on the male die member which is formed with male die elements also in the form of the characters to be produced, and by applying a compressive force to the plate blank, an identification plate is formed with indented retroreflective characters devoid of air bubbles or the like.

Abstract: A method and apparatus for forming a longitudinal hem along one edge of a fabric using a hot melt adhesive for securement of the hem. The fabric is advanced along a predetermined path of travel while one longitudinal edge portion of the fabric is directed through an elongate heating chamber and heated to an elevated temperature. The heated edge portion of the fabric then passes through a folding station and the fabric is folded to form a hem. A stream of molten hot melt adhesive is deposited between the overlying fabric layers which define the longitudinal hem and pressure is applied to the hem to cause the molten adhesive to spread and penetrate into the fabric layers and to also prevent relative movement between the fabric layers until the adhesive is sufficiently cooled to secure the hem together.

Abstract: The proposed method for insulating the covering of cables resides in high-frequency heating of the cable conductor wrapped with tapes from polymer materials, such as polyimidepolytetrafluoroethylene films, in a transverse magnetic field over a period of time required to reach the material softening temperature and maintaining this temperature until the polymer material is baked, which is done in a longitudinal magnetic field. The device for carrying out the above method comprises an induction loop heater and a cylindrical induction heater arranged coaxially therewith. The invention can most advantageously be used to provide for quality insulation of cables up to 70 sq. mm in cross section.

Abstract: The invention relates to the monitoring of the filling effectiveness during the filling operation of a waterproof or filled telecommunications cable on a manufacturing line, and includes measuring the capacitance change per unit length of an outer pair of insulated conductors in the cable, measuring the capacitance change per unit length of an inner pair of insulated conductors in the cable, determining any deviations in the measured capacitance changes and utilizing such deviations by feedback control to eliminate further deviation, as well as determining the point of deviation along the cable length.

Abstract: The invention pertains to a novel method of forming a flexible, tapered end on a thermoplastic molding strip. The strip is of the type having a top surface shaped to provide desired protective and/or decorative functions. The bottom surface is generally flat for bonding to a desired article such as a side panel or door of an automotive vehicle. In a preferred embodiment, the method comprises removing a V-shaped notch from the end of the strip, with the opening of the V at the end, to form adjacent triangular shaped legs. The notched end is then bent to stretch the bottom surface and the legs are drawn together to form the taper. The edges of the legs adjacent the taper are bonded together only at the pointed end. Multiple cuts are then made into the bottom surface of the strip, perpendicular to the line formed by closing the notch, between the tip and the original apex of the notch.

Abstract: Capacitance unbalance-to-ground between conductors of a twisted pair, each of which may be insulated with at least a layer of cellular plastic insulation, is maintained within acceptable limits by controlling the extrusion of the insulation to maintain the measured coaxial capacitance and associated outside diameter of the insulated conductors within a range of values which correspond to acceptable capacitance unbalance-to-ground values.

Abstract: Panels of cloth or sheet material are reeled out in parallel plane layers and joined in pairs along alternate edges to form a folded structure which can be deployed around at least a part of a tabular iceberg and then allowed to extend concertina-fashion to provide a protective jacket next to the flanks of the iceberg. The upper part of the skirt can be of more robust material in order to stand up to the action of waves and swell, while the submerged portion (deployed concertina-fashion) serves to keep warm water from coming in contact with the iceberg. The skirt is intended to protect icebergs being towed from antartic seas to the tropics.
