Abstract: The nestable case is generally box-shaped with four side walls and a base. The side walls include upper fixed wall portions that are rigidly joined together to define a mouth portion of the case. The side walls also include moveable wall portions that are hinged to corresponding foldable sections of the base. When the case is fully loaded with containers the moveable wall portions and foldable sections of the base are in an expanded limit position. When the case is emptied the moveable wall portions and the foldable sections of the base can be moved to a contracted condition, which permits nesting of similarly empty cases. Fully loaded cases in the expanded limit position can be stacked one upon the other or arranged in a pinwheel configuration. A further embodiment of the invention includes provision of a shield at corner clearance openings to protect bruising of any portions of the containers that project from the corner clearance opening.

Abstract: A device for correctly applying a plaster dressing or cast to treat a fracture or dislocation of a human body segment. The device comprises a split flexible plastic member normally urged into annular shape and having an outwardly extending peripheral edge portion and a skirt portion depending therefrom. This plastic member is adapted to be placed on the body segment with the skirt portion in surrounding relation thereto whereby the outwardly turned peripheral edge portion defines the limit of the plaster cast or dressing. After the cast has been applied to the body segment and has been set, the plaster member is easily removable from under the cast.

Abstract: An embroidered design adapted to be heat sealed to another article. The design is embroidered on a substrate made of woven polyester fabric. The substrate is bonded at the underside thereof to a low melt thermoplastic adhesive film to form a lamination. The design is thereafter traced along the outer and inner peripheries thereof with a severing tool to remove all portions of the lamination except only the design proper consisting of the embroidering thread and the plastic film portions thereunder. The design may then be heat sealed to another article such as a garment with the garment proper being exposed between adjacent portions of the thread to simulate a design embroidered directly onto the garment.

Abstract: A heater assembly for heating a surface such as the rear window of an automobile. A plurality of heater elements are adhesively secured onto the surface in generally vertically spaced horizontally extending direction. A pair of busbars are adhesively secured onto said surface in generally vertically extending direction overlying the heater elements adjacent the opposite ends thereof. End portions of the heater elements which extend beyond the busbars are wrapped around the busbars and firmly retained by a pair of covering members which are secured in juxtaposed relation to the busbars for providing good electrical contact between the heater elements and the busbars.

Abstract: A suspension system suitable for a flux gate compass having compass windings (14) includes a ball joint (4,5,6) which permits both tilt and twist about a vertical axis, and a separate alignment element (16) for causing the windings to follow twisting motion of the fixed structure. The alignment element takes the form of a flexible printed circuit made into a double spiral form and carrying electrical conductors to provide the electrical connections to the windings. A zig-zag shape may be used instead of a spiral. The suspension does not suffer from the geometric imperfections of a Hooke's joint and avoids the need for separate flexible conductors which can interfere with the suspension operation and can break.

Abstract: This invention relates to a process of selective galvanizing of materials adapted to be galvanized by immersion in hot conditions characterized by the application on said materials, prior to immersing them into a bath of melted zinc, on those spots on which no galvanizing is desired, calcium carbonate alone, or a mixture thereof with an alkali metal chlorinated-s-triazine trione, or with an alkali metal salt of an oxygen-containing chlorine compound.

Abstract: A system for measuring the level of liquid stored in deep tanks or vessels that allows the use of a lightweight, relatively non-toxic, non-corrosive gauge fluid of normal column height is disclosed. The system discloses a diaphragm manometer that alters a greater pressure from the tank liquid into a lesser pressure from the gauge fluid permitting such gauge fluid to be lightweight and making it unnecessary to use high density fluids which are usually toxic, contaminating and have other undesirable handling characteristics. The device can be used for open tanks, or, with adaptations, for sealed tanks. For open tanks, the device provides two sealed chambers having two opposing diaphragms. For sealed tanks, pressure neutralizing elements are added with one device providing three sealed chambers and two diaphragms with neutralizing connectors, and another providing three sealed chambers and three diaphragms.

Abstract: A storage device having a plurality of shelves which is portable and removably supportable on a wall mount. The top wall of the device is provided, at its juncture with each sidewall, with a passageway for receiving therethrough a support rod whose rear end is removably supported on the wall mount. The front ends of the support rods are interconnected by a cross bar whereby there is defined a rectangular frame for suspending the storage device from the wall mount. The shelves are provided with rigid panels which extend rearwardly of the storage device a predetermined distance so that the rear ends of the panels abut the wall to provide added support for the device.

Abstract: A device for marking the location on a wall in which to place a nail or hook for suspending an article, such as a picture frame, of the type having a supporting cord on the back thereof. The device comprises a carrier member adapted to be suspended by a flexible element in a general vertical direction. The carrier member is provided with a marking pointer extending from one side of the carrier member in a horizontal direction. The pointer is grooved adjacent the carrier member for firmly receiving the cord of the article to be hung. The carrier member, together with the article supported by engagement of its cord with the pointer, is positioned at the desired location on the wall to make an impression on the wall for locating the hook which will automatically permit the article to be supported on the wall at the desired location.

Abstract: A molded breast cup for use in brassieres and other garments. The breast cup comprises an outer layer, an inner layer and an intermediate reinforcing layer sandwiched between the outer and inner layer. A fusable material is provided on the surface of the intermediate layer confronting the outer layer and on the surface of the inner layer confronting the other two layers. The three layers are aligned in juxtaposed relation and molded between heated male and female molding members to form a unitary molded breast cup in which the intermediate layer provides reinforcement for the cup.

Abstract: A packaging device comprising a pair of shells adapted to be assembled into closing engagement to define an enclosure for an article of merchandise. A hanger element is releasably securable to the packaging device, extending through a slot defined in the upper part thereof. The hanger element includes means to prevent displacement or removal thereof when the two shells are assembled. The hanger element can be dispensed with leaving the packaging device essentially unblemished, whereby the packaging device can be selectively used with or without the hanger element.

Abstract: An attachment to a camera for obtaining instantaneous photographic prints of pictures taken by the camera is disclosed. The conventional back cover of a camera is replaced by a modified back cover having a cutout in which there is mounted a fiber optic face plate. A conventional Polaroid back is attached to the modified back, and the fiber optic face plate transfers the image formed on the focal plane of the camera to the plane of the Polaroid film, so that a contact print can be instantaneously obtained of the picture taken through the camera's regular optical system.

Abstract: A surgical cutting instrument includes an electrically heated cutting edge and an automatic control system for maintaining the cutting edge at a constant high temperature for sterilizing the blade, cutting tissue, and cauterizing the incised tissue to reduce hemorrhage from the cut surfaces of the tissues (hemostasis).
