Abstract: A method of continuously insulating a body of substantially uniform cross-section, such as a pipeline, so that it can be either wound on a reel for transportation to a site where it can then be unreeled, or by allowing the application of the insulation on location as the pipeline is unreeled.

Abstract: A container having two side panels, a bottom panel and lid panels all diecut from a single paperboard sheet and two end panels of relatively thick rigid fiberboard opposite one another and joined to edges of the side and bottom panels. The end panels have sufficient strength and are configured such that the containers may be arranged in an accurate stack with the containers interlocked with one another. Each container has a pair of lid panels that fold together to close the container or may be folded back and locked against the side panels by tabs to hold the container open for convenient filling.

Abstract: A method of computing parasitic capacitances between multiple electrical conductors within an electric circuit computes a division of the circuit's physical layout into a plurality of windows. The parasitic capacitances associated with the conductors of each window are computed, and the results for the various windows combined into a matrix of parasitic capacitances for the overall circuit. The windows are preferably overlapped, with the capacitance values for conductor pairs located in more than one window averaged. Complex polygons are fractured into simpler shapes by extending a ray from a vertex of the polygon to intersect an opposed segment, and defining the peripheries of the simpler elements as comprising the ray and respective different portions of the original polygon's periphery. Rays may be extended in a x,y pattern from multiple vertices of the polygon until a ray is located that extends through the polygon's interior, with the fracturing performed along that ray.

The cap mechanism functioning in response to movement by the cap carriage which in turn is moved by printer's print cartridge carriage when it leaves a printing zone for servicing by the maintenance station.

Abstract: A lighter-than-air aircraft includes a rigid platform having cargo and passenger compartments and gas bags attached to the platform for holding a gas having a density less than air, thus imparting lift to the platform. The bags are arranged in pairs, there being a pair of spaced apart upper bags along the upper surface of the platform and a pair of spaced apart lower bags along the lower surface. While the bags cover portions of the upper and lower surfaces, both surfaces remain exposed along the longitudinal centerline of the platform, and here the platform is provided with vertical ducts and bays. The ducts house motors and propellers which drive air through the ducts and thus impart a vertically directed force to the platform. The bays hold containers which are lowered from and raised into the bays with a crane that moves along tracks extended along the upper surface of the platform.

Abstract: A device and associated method comprising a probe (18) for drawing throttled two-phase steam into a tank (26) which has been evacuated and which can be closed when the pressure of the sample steam in the tank equals the pressure of the source steam mixture (14). The throttling tank operates on the basic thermodynamic principle that a two-phase mixture when throttled into a closed tank becomes superheated. The state of the superheated mixture is determined by temperature and pressure measurements (42, 36). The initial state of the source mixture can then be determined by application of the First Law of Thermodynamics, which is considerably simplified as a result of the way in which the sample is drawn.

Abstract: A self contained sensor module mounted on a power transmission line. The module is capable of measuring various parameters such as line current, voltage, conductor temperature and ambient temperature. The parameter values are processed by sensor electronics which digitize and periodically transmit the values to a ground receiver. The module power supply is coupled to the transmission line conductor by a transformer. The line conductor extends through a magnetic core in the module housing. A secondary shunt magnetic core is provided to limit induction of high voltages as a result of excess current flowing through the transmission line conductor.

Abstract: Self contained radio transmitting modules are mounted on power conductors at various places along electrical transmission lines. The modules are capable of measuring current, voltage, frequency and power factor (or the Fourier components thereof), the temperature of the conductor and the temperature of the ambient air. Up to fifteen modules may transmit on a single channel to a single local receiver. Each module transmits at intervals which are an integral number. The intervals between transmissions of all modules do not have a common factor and the average interval is the desired transmission rate.

Abstract: A self contained hot stick mounted radio transmitting module may be permanently mounted on or temporarily pushed against the power conductor of an electrical transmission line. The module is capable of measuring the potential difference between the conductor and ground. The module digitizes and transmits the value of the potential difference to a ground receiver. The module is donut shaped and opens like a pair of jaws. The contact with the power line is accomplished via a resilient conductive elastomer that covers the surfaces in contact with the power conductor. The potential difference between ground and the power conductor is measured with an operational amplifier in an integrating configuration to convert the leakage current from the module to ground into a proportional voltage from a low impedance source. The integrator outputs a voltage proportional to the current flowing into the equivalent capacitance formed by the outer surface of the module and ground.

Abstract: A "hot-stick" mountable sensor module for attachment and removable from a live power transmission line. A tool is insertable into a mounted module to attach the module to the tool and permit removal of the module from the line.

Abstract: A method of applying solventless varnish to stator windings in electrical machinery. A magnetic core having a plurality of stator windings disposed in the slots of the core is positioned above a tank containing a solventless varnish, and the tank is then raised to immerse the end turns of the windings on one end of the core into the varnish. The windings are energized to heat them and the varnish which adheres to the end turns to reduce the viscosity of the varnish. The tank is then lowered and the stator and windings are inverted so that a portion of the reduced viscosity varnish which adheres to the end turns flows downwardly through the slots of the stator. This is repeated until varnish begins to flow freely through the slots to the other end, thereby indicating that good coating of the winding within the slots has been accomplished.

Abstract: A friction braking system located entirely inside an induction motor of an appliance quickly stops rotation of the rotor in the appliance motor, for example such as a food processor, whenever the A.C. electrical power is turned off. Thus, rotation of any tool being operated in the appliance is quickly stopped, whenever the electrical power is interrupted. The rotor in the induction motor is axially slidably mounted on the motor shaft and is keyed to the shaft for permitting axial shifting displacement of the rotor relative to the stator while preventing any angular displacement of the rotor relative to the shaft. Consequently, the rotor and shaft always turn and stop as a function unit. A friction brake lining is affixed within the motor housing offset from the axis of the motor shaft as far as practicable. A disc brake mounted onto the rotor has an annular friction braking surface positioned for engagement against the brake lining.

Abstract: Self contained radio transmitting state estimator modules are mounted on power conductors on both sides of power transformers in electrical substations and on power conductors at various places along electrical transmission lines. They are electrically isolated from ground and all other conductors. These modules are capable of measuring current, voltage, frequency and power factor (or the fourier components thereof) the temperature of the conductor, and the temperature of the ambient air. The modules transmit these parameters to local receivers. The receivers are connected by an appropriate data transmission link, to a power control center which allows determination of the state of the power system. The module measures the Fourier components of voltage and current over a number of cycles and transmits the components to the local receiver.

Abstract: A self contained hot stick mounted radio transmitting module may be temporarily pushed against the power conductor of an electrical transmission line. The module is capable of measuring the temperature of the conductor, and the temperature of the ambient air. It may also measure the electrical potential of the conductor. An alternative module is also capable of measuring current, potential, frequency and power factor (or the Fourier components thereof). The modules transmit these parameters to a local receiver where the data may be displayed. The receiver also may be connected by an appropriate data transmission link, to a power control center.The modules are donut shaped and open like a pair of jaws. One or more spring loaded temperature probes are located such that they may be pushed against a power line when a "donut" is mounted to a hot stick with the jaws open.Power to an open module is supplied by a battery.

Abstract: An improved and simplified device for removal of deposits on furnace walls is disclosed which can be operated by a single individual. The device is characterized by rotating scrapers driven by internally-contained air-powered motors. The horizontally opposed scrapers are journalled on each end to pairs of arms which are connected together at a pivot spaced from the journals. Air cylinders, powered from a common source with the air motors, spread the arms apart simultaneously with activation of the air motors to bring the rotating scrapers in contact with the furnace walls.
