Abstract: A telephonic distribution panel assembly is comprised of three identical panels which are removably attached to one another. These three identical panels are arranged to form a three sided frame. The assembly provides easy access to various types of telephonic equipment which may be mounted to the frame.

Abstract: A method of production of a miniaturized bus bar is presented wherein a layer of unfired ceramic is positioned between a pair of bus bar conductors.

Abstract: A mounting block for solderless connectors has a retainer and a body section which defines slots for housing terminal defining conductive elements to thereby define rows and columns of terminals. The conductive elements are formed from wire to define linearly aligned plural loops between which wires may be inserted. The block supports the conductive elements so that relative lateral movement between the loops is precluded.

Abstract: A membrane keyboard and method of formation thereof is presented in which the spacing and insulation between fixed and movable circuit layers is achieved by a dielectric material screened or otherwise applied to one of the circuit layers in a predetermined pattern. The dielectric pattern has openings to permit electrical contact between layers, and the dielectric pattern includes a discontinuous pattern of dielectric material on at least one of the contact elements to maintain separation between the contacts while still permitting actuation of the device.

Abstract: A method of assembling a miniaturized bus bar which has high capacitance comprises forming a layer of ceramic material directly upon a bus bar conductor or directly upon a supporting metal strip which is attached to a first bus bar conductor. The exposed surface of the layer of ceramic material is subsequently mechanically and electrically bonded to a second bus bar conductor which extends parallelly with respect to the first bus conductor.

Abstract: A level indicating device comprises a compressible container, which is charged with a measuring liquid, and a flexible transparent tube having a first end immersed in the liquid within the container. The second end of the tube may be affixed to a support which has a reference level marking means mounted thereon. When the device is in use, the surfaces of the fluid in the container and in the second end of the tube are exposed to the ambient atmosphere whereby, when in equilibrium, both surfaces will be at the same level.

Abstract: The granulation of molten material, blast furnace slag for example, is accomplished by wetting the slag with a stream of water and thereafter transporting the thus formed granules away from the point of granulation with the water stream. Water consumption is minimized and average grain size increased by employing a multi-layer water stream defined by currents having different temperatures and pressures.

Abstract: An improved method of manufacturing electrical and electronic circuits is provided wherein an improved conductive ink is employed to define the pathways of current flow. This improved conductive ink is comprised of conductive particles, thermosetting binder and a multifunctional isocyanate. The isocyanate provides cross-linking between the conductive ink binder and the surface upon which the ink is applied and establishes a bond with enhanced moisture durability.

Abstract: A fuel stream comprising a combustible pulverized material entrained in a carrier gas is formed and subsequently injected into a blast furnace with the hot blast air without any detrimental effect on the hot air blast and with minimum energy consumption. The volume flow rate and pressure of the carrier gas are controlled as functions of the furnace pressure and the pulverized material feed rate is simultaneously controlled as a function of the carrier gas pressure drop.

Abstract: Control over the direction and inclination of a charge distribution chute within a blast furnace is accomplished with a compact and reliable drive mechanism. The drive mechanism includes a rigid control rod for varying chute inclination angle and a gear drive which translates angular position commands in the form of rotation about a vertical axis to reciprocation of the control rod. The control rod and its gear drive rotate with the chute while simultaneously varying the inclination angle.

Abstract: A molding compound is disclosed comprising a diallyl phthalate compound and capsules of water.

Abstract: A valve for opening and closing a fluid conduit of the type having a generally wide cross-section, the conduit having a transverse slit therein to allow for movement of a shut-off member into and out of registration therewith. The shut-off member has a spherical shape and cooperates with an apertured member which defines a surface of the same sphere. Both the shut-off member and the apertured member may be arcuately displaced, about a common axis, to establish either a closed or opened conduit with leakage from the conduit in either the opened or closed position being prevented by peripheral portions of the shut-off member and apertured member.

Abstract: An improved corrosion resistant pipe and method of manufacture is presented wherein a phosphorus copper or phosphorus copper alloy pipe is subjected to a special heat treatment step which forms an internal oxide coating. A pipe produced in accordance with the invention is characterized as having a carbon content on the inside wall of 0.05 mg/dm.sup.2 or less and an internal oxide coating having a thickness ranging from 0.1 to 5 microns. Notably this improved pipe has a good resistance to corrosion, even when exposed to chemically agressive liquids.

Abstract: An air deflector for motor vehicle windows for directing air into the interior of a motor vehicle, the air deflector including a mechanism for releasably securing the air deflector to an open window and a plate extending from the securing mechanism to the exterior of the motor vehicle to divert and direct air through the open window into the interior of the motor vehicle.

Abstract: An electrical panel connector hold-down adapter which permits electrical cable connectors of various size and shape to be easily and reliably secured to mating electrical panel connectors.

Abstract: An aerial device in the form of a wing having upper and lower flexible layers and a leading edge and a trailing edge, a wall of the wing having an opening facing outward from the bottom or a side of the wing forming an inlet for flow of pressurized air into the wing, and a normally open flexible valve for the opening closeable by the air pressure to seal the opening when pressurized air is admitted to the wing.
