Abstract: An easy-to-use and inexpensive work glove is provided. For this purpose, the work glove integrally comprises a first section for covering a region extending from a forearm middle portion between the wrist and an elbow to a hand, and a second section for covering an upper arm above the elbow, the second section extending from the first section.

Abstract: A battery comprised of a generally rectangular electrochemical cell that has two battery leads attached to current collectors extending from one side thereof. A package formed from a sheet laminate has a cavity formed therein that defines an opening for receiving the cell and portions of the leads. A flange extends around the opening. A cover overlays the cavity and the flange. The cover is joined to the flange and forms a seal that hermetically seals the electrochemical cell within the cavity. The package has two, non-rectangular corners. The cover and the flange in the vicinity of the corners are shaped to allow the flange to be bent along the at least three sides in a manner wherein the flange is positioned adjacent the three sides, but the flange is not tucked or overlapped onto itself at the two, non-rectangular corners.
Abstract: A Conveyor furnace for firing pipe-shaped objects with the following characteristics:
1.1.1 a furnace floor,
1.1.2 a furnace ceiling,
1.1.3 a two lateral furnace walls, which connect the furnace floor with the furnace ceiling, forming a furnace channel,
1.2 the furnace floor has at least one opening running in the axial direction of the furnace channel,
1.3.1 at least one transport unit that extends from a motor section below the furnace floor through the opening to a transport section in the furnace channel, and
1.3.2 which can be driven along the opening,
1.4 the transport section is designed to hold, in a horizontal position, at least one pipe-shaped object,
1.5 in the furnace channel below at least one part of the object to be fired, which is freely achievable, a device is arranged, onto which the object first rolls up, with its freely achievable part, and then rolls down.
Abstract: A component for use in manufacturing articles such as printed circuit boards, the component comprising:
a sheet of copper foil which, in a finished printed circuit board, constitutes a functional element;
a substrate sheet of aluminum which constitutes a discardable element, and
a protective coating layer on a surface of said substrate, one surface of the copper sheet and the coating layer on said substrate aluminum sheet being essentially uncontaminated and engageable with each other at an interface, and the uncontaminated surfaces of the sheets being manufactured together to define a substantially uncontaminated central zone inwardly of the edges of the sheets and unjoined at the interface.
Abstract: A lining for a bottom of a metallurgical vessel, comprising an impact pad having a plurality of close-packed, pre-formed, high-temperature, high-density refractory bricks, the pad having an upper impact surface, and a monolithic slab of a high-temperature refractory material encasing the pad, the slab encasing the pad wherein the upper surface of the impact pad is exposed.

Abstract: A tool for bending ceiling support rods. The tool includes a first lever and a second lever. The first lever has a first handle portion and an associated first jaw portion, the first jaw portion has a contoured surface. The second lever has a second handle portion and an associated second jaw portion, the second jaw portion has an edge. Means are provided for pivotally mounting the first lever with the second lever, wherein the first jaw portion and the second jaw portion are opposite each other and are movable relative to each other when the first and second handle portions are compressed. The edge of the second jaw portion is movable toward the contoured surface of the first jaw portion when the first and second handle portions are compressed toward each other.
Abstract: A method of forming battery leads, comprising the steps of: forming a plurality of aligned, spaced-apart elongated openings in a rectangular, metallic sheet, the metallic sheet having side edges and a width between the side edges equal to a desired length of a battery lead, the openings extending between the side edges and being aligned in a row that extends parallel to the side edges; treating areas of the surfaces of the metallic sheet between the openings to enhance the adhesive properties thereof; applying a strip of an adhesive/sealant material to each side of the metallic strip over the area and the slots; and cutting a battery lead from the metallic sheet by cutting the metallic sheet widthwise through each opening from one side edge to the other side edge.
Abstract: In a transfer system using movable bodies supported and guided by a rail through a plurality of guided devices so that they are capable of moving in a given path, when a movable body taken out from the given path is transferred to a separate given path or restored to the original given path, the movable body needs be separated or joined while being longitudinally moved, thus requiring a long path for separating or joining. The invention provides a system comprising a group of guided devices relatively turnably connected to main bodies of the movable bodies through vertical shafts, a plurality of divisional rail bodies capable of supporting the group of guided devices and disposed in a set path portion in the given path, turning means for turning these divisional rail bodies around vertical axes, and a group of transverse rail bodies disposed laterally of the set path portion such that the divisional rail bodies turned for separation from the rail can be connected.
Abstract: A screw conveyor apparatus including a ribbon screw (4) provided in a cylindrical casing (1). The ribbon screw (4) has rotation rings (12) attached to an intermediate portion thereof. Outer peripheral supporting sections (11) are provided for rotatably supporting the corresponding rotation rings (12) on the casing (1). This configuration prevents the ribbon screw (4) from being bent or expanded under a load of conveyed materials, thereby enabling the materials to be conveyed along a steep slope up to a high portion.
Abstract: A cable for use in a high-frequency current feeding equipment constituted by passing an inner bundle (A) of wires (2) disposed at the same distance from the center of multiconductor cable (1) and outer bundles (B and C) of wires (3) through a ferrite (5) in such a way that the ampere-turns thereof are the same. The counter-electromotive force generated because of the difference of the spatial arrangement between the inner wires (2) and the outer wires (3) caused when stranded is canceled, and the current phases and current values of the wires (2 and 3) are forced to be exactly the same. Therefore, an increase in the resistance due to the proximity effect is prevented, and thereby the multiconductor cable (1) can be used as a high-frequency current cable.
