Abstract: The method and apparatus of the invention described herein provide confidential communications between two or more stations whereby the exchanged messages themselves provide the necessary enciphering keys for the messages to be encrypted and transmitted from each respective station. A full duplex communications loop is utilized between stations and the messages are exchanged substantially simultaneously.

Abstract: A method and apparatus for authenticating documents, utilizing the ferroelectric properties of poled polymeric materials. The properties displayed by the poled materials are detected in order to authenticate the documents to which they are affixed. The poled polymeric material can be used as a protective coating or covering for an indentifying photograph and/or signature and can be applied to a document in such a fashion that heat is needed to remove it. The ferroelectric properties of the poled polymeric material virtually disappear when the material is subjected to critical temperatures, such as those necessary to remove the material from the document. The absence of these properties therefore, signifies that the document has been tampered with.

Abstract: The instant invention relates to an apparatus and method for inspecting the structural integrity of drill collars used in the drilling of oil and gas wells.

Abstract: An adjustable divider for a shelf or a drawer of a file cabinet is formed entirely of a spring wire. One end of the spring wire is configured as an engagement portion which has a longitudinal portion for engaging within an acute angle between a first wall portion and a bottom surface of a notch in a horizontal base which supports files, books, or any other items to be maintained in an upright orientation. A second wall portion of the notch is substantially orthogonal to the bottom surface of the notch and maintains the longitudinal portion in resilient compression against the first wall portion of the notch.

Abstract: There is provided a process for infiltrating a compacted ferrous powder metal body with copper or a copper alloy which process is characterized by presintering the ferrous metal body at a temperature of from about 1875.degree. F. to a temperature below the melting point of the infiltrant, and then in the same furnace, raising the temperature above the melting point of the copper or copper alloy infiltrant for a period sufficient to infiltrate the powder metal body. This process is more economical than the prior double run infiltration processes and provides excellent impact strengths and tensile strengths.

Abstract: This invention relates generally to an ultrasonic wheel probe for rolling along a workpiece to be tested for flaws, having a plurality of ultrasonic acoustic transducers and an acoustic barrier that rest in a coupling fluid. The instant invention comprises an improved means for detecting the distance between the transducer array and the surface of the workpiece.

Abstract: An improved method for mixing and/or drying particulate material is achieved with a housing having a substantially cylindrical portion and a tapered portion arranged coaxially therewith. A motor-driven rotor is arranged within the housing and is provided with a plurality of impeller blades which are affixed at one end to the shaft member. The impeller blades extend substantially radially outwardly toward the internal surface of the housing means. Each blade has a dual pitch characteristic which, in combination with a direction or rotation permits establishment of first and second flows of the fluidized material in opposite directions in the housing. The first and second flows are combined in the tapered section of the housing wherein there is provided a terminating impeller which agitates the combined flows in response to rotation of the central shaft. A material flow of the particulate material with sufficient velocity will fluidize the material being mixed or dryed.

Abstract: There is provided a substantially fully dense powdered metal composite comprising a highly conductive metal or metal alloy matrix having dispersed therein discrete microparticles of a refractory metal oxide and discrete macroparticles of an additive metal or metal alloy, such as a nickel/iron alloy. The respective components undergo minimal alloying because sintering is not utilized in forming the composite. These composites are characterized by high thermal or electrical conductivity and a desired property attributable to the composite forming additive metal or metal alloy. The composites are useful in forming lead frames for integrated circuit chips, electric lamp lead wires, and electrical contact members.

Abstract: This invention relates to a device for displaying photographs or other graphic materials. The device is constructed out of two pieces of semi-rigid flexible, transparent plastic material which are pre-folded to form a free standing, display enhancing device.

Abstract: An improved shelf is provided with a divider arrangement formed of a substantially resilient material having portions for engaging with vertical and horizontal members of the shelf, the divider arrangement providing stiffening and support for the shelf.

Abstract: A merchandise dispenser for storing and dispensing a plurality of items aligned within the dispenser and eased toward the front of the dispenser by a retractable member which is biased to push the remaining line of items forward when the first item in the line is removed. The dispenser is provided with an indicator which automatically indicates the quantity of items remaining in the dispenser.

Abstract: The instant invention is an optical device intended primarily as a mirror for the application of cosmetic products, procedures or for other fashion related items. The mirror device permits the user to view two images of himself, or herself, either side-by-side or separately. One image is a standard mirror image with left and right reversed and the other image is the true non-reversed image perceived by others. The observer perceives each image as appearing on a single rectangular viewing surface with more of a three-dimensional, vivid and colorful appearance than a normal plane mirror. This mirror can be easily assembled and transported in a compact version.

Abstract: An improved binder for sheet material. The binder includes a cover or backing member formed of paperboard or plastic, and a pair of hinge assemblies are attached to the inner surface of the cover. A standard binding mechanism is interconnected between the hinge assemblies and serves to retain the sheet material. Each hinge assembly includes a metal hinge plate that is secured flatwise to the cover by a plurality of stamped out prongs. Each prong is generally triangular in configuration and is provided with a curved pointed tip. The prongs have a length substantially greater than the thickness of the backing member and when embedded by pressure, the configuration of the prongs causes the prongs to curl within the cover, so that the prongs are completely embedded in the cover and not exposed on the outer surface of the cover.

Abstract: The present invention relates to a venting device for a sealed container, and more particularly to a safety venting device for a Lithium cell. The venting device is located on one of the two ends of a sealed container. The vent is comprised of a circular member which is recessed in the container end whereby it is concave with respect to the exterior of the container. Extending between the circular member and the container end are scored lines of weakness. As pressure increases in the container, the circular member deflects so as to develop stresses which become concentrated on the scored lines causing them to rupture at a predetermined pressure.

Abstract: A cosmetic composition of the type which is useable in the form of a cosmetic stick for applying the cosmetic composition to human skin is provided with acetylated monoglyceride in the form of a waxy solid, beeswax, and isopropyl myristate in a predetermined composition to produce a co-efficient of friction for the cosmetic composition which is greater than approximately 0.5. The cosmetic stick can be applied to the body to produce a massaging action, without causing a greasy feeling. In preferred embodiments, moisturizers such as stearic acid and cetyl alcohol are included in the composition. Additionally, emollients, such as propylene glycol, isopropyl palmitate, and dimethicone and an antioxidant formed by the synergistic combination of vitamin E and ascorbyl palmitate (Vitamin C) may also be included in the combination. Methods for preparing aqueous and nonaqueous cosmetic compositions are disclosed.
