Abstract: ABSTRACT METAL COATING OF FIBERS      Fibers are coated with a metal layer by applying onto the fiber a relatively high viscosity slurry comprising an alloy in the form of liquid and solid phases.  This allows application of metal coatings on layers that do not "wet" with the liquid metal. For example, an optical fiber having a soft polymer layer to reduce microbending losses is coated with a metal to prevent moisture entry.  An alloy of Bi-Sn or In-Sn, among others, allows coating at a relatively low temperature to prevent polymer degradation.  Other fibers for various uses can also be advantageously coated with this technique.

Abstract: Abstract Directional solidification of a single crystal superalloy article may be accomplished using a mold with a starter section, and a selector section to convert columnar growth from the starter into single crystal growth.  In such a process, the devia-tion of [001] crystallographic orientation with respect to the longitudinal axis of the article being formed is reduced from 9 degrees to 5 degrees by controlling the heat transfer in the starter section. A stepped starter section, wherein the lower subsection has a volume of 52-98% of the total starter volume, and wherein the upper subsection is relatively small in lateral dimension, has been found most useful.  When the solidification interface moves into the smaller width upper subsection, it becomes more nearly planar, and results in improved columnar growth in the starter, and in reduction in the crystallographic deviation of the article.

Abstract: ABSTRACT OF THE DISCLOSURE          Data logging apparatus for use in cathodic protection surveys by measuring the potential difference between a buried pipeline and the soil adjacent to it is described.  The data logging apparatus is based on a CMOS microprocessor-based electronic circuit which digitises the analog input voltages and displays these on a liquid crystal display.  The displayed voltages can be entered at the discretion of the surveyor into a random access memory for permanent storage.  The unit has a keyboard which permits the user to enter data into the memory by depressing a key.  Codes corresponding to various topographical features such as a river or railroad crossing can also be entered and displayed to provide some reference to the potential measurements.  This coded information can also be stored in the random access memory via the keyboard.  The unit operates under the control of a microprocessor in accordance with a number of predetermined programs stored in an erasable programmable read-only memory (EPROM) contained in the unit.  The stored data can be transferred under the control of the unit to an external EPROM or it can be transmitted via a modem over a telephone line to a host computer for analysis and presentation of the data in graphical form to enable corrosion problems in pipelines to be rapidly identified.  The data logging unit also has application outside cathodic protection surveys.

Abstract: Electrogasdynamically Assisted Cyclone System For Cleaning Flue Gases At High Temperatures And Pressures Abstract A system for separating solid particles from the combustion products of coal in which high temper-ature, high pressure flue gas containing the particles is directed tangentially into a cyclone separator so that the relatively large particles are driven by centrifugal forces to the inner wall of the separator. Electrical charges generated at ambient temperature are blown into the cyclone separator via aerosol charge-carriers which charge the relatively small particles in a manner so that the small charged particles are attracted to the wall, which is of an opposite polarity, and are scrubbed off the wall by the larger particles. A double-cone flow regulator is positioned in the path of the aerosol charge carriers and the particles to direct the carriers and particles toward the inner wall.  An outlet is provided at the lower portion of the cyclone separator for discharging the separated particles and an additional outlet is provided for discharging the clean gas.

Abstract: Containers 6, adapted to receive a product which does not of itself give off a gas, receive an amount of a liquefied pressurizing gas from a tank 1 provided with an outlet nozzle 3. The containers 6 are aligned on a machine 7 which conveys them, in the direction of the alignment, under the tank 1 which is provided with trunnions 2 and is oriented in such manner as to be pivotable about an axis parallel to the direction of alignment. A control device 8 regulates the angular position of the tank 1. The amount of the liquefied pressurizing gas received in each container depends on the angular position of the tank relative to the vertical position. Thus, in the case of containers having a round section, the amount of liquefied gas received in a container is maximum when the nozzle is on the line of alignment of the containers and passes along a diameter of the container section and smaller when the tank has been pivoted away from its vertical position and the nozzle passes along a chord of the round container section. The invention is particularly applicable to the pressurizing of cylindrical cans adapted to contain non-gaseous drinks.

Abstract: ABSTRACT OF DISCLOSURE A net structure in accordance with one aspect of the invention includes a handle having a rigid hoop secured thereto.  A flexible bag having an openable top portion defining the mouth of the bag has a plurality of connector means secured at spaced intervals thereto.  These connector means are also freely slidably attached to the rigid hoop to pendantly secure the bag to the hoop.  These connector means are moveable from a relative positional arrangement wherein they are spaced apart about the hoop to define the open mouth position of the bag to a second relative positional arrangement wherein such connector means are grouped together on the hoop to define the closed mouth position of the bag.  As a characteristic feature of the invention, an elastic member is connected between selected ones of the connector means such that as the latter are made to slide along the hoop between the first and second relative positional arrangements, the distance between said selected ones of the connector means is varied.  As this variation occurs, the elastic member is first made to increase in length and then allowed to decrease in length and to at least partially relax whereby to assist in resilently retaining the bag in both the open mouth and closed mouth positions thereof and/or resiliently biasing the bag toward the open and closed mouth positions thereof.
