Abstract: D-2,397  C-3,027 Abstract of the Disclosure:  A method of forming a through-the-partition intercell connection between adjacent cell groups in a multicell, lead-acid storage battery.  Plate strap lugs are positioned on either side of an aperture in a partition between adjacent cells.  One of the lugs has a substantially flat face thereon abutting the partition while the other and opposing lug has a cavity formed in its partition-abutting face, which cavity is substantially axially aligned with the aperture during positioning.  The battery is rotated 90° such that the cavity-bearing lug lies beneath the flat-faced lug.          The flat-faced lug is then arc welded through its center backside such that the melt formed flows by gravity through the aperture in the partition and into the cavity in the opposing lug.  After the battery is inverted and the center backside of the cavity-bearing lug arc welded to fuse the lugs together, cold pressing the lugs together completes the connector forming process.

Abstract: ABSTRACT           A quantity of ammonium ion-producing compound, such as ammonium salt, is confined inside a container having an aperture or aperatures covered by a water permeable membrane.  The container is placed under water at a desired location, and water passes into the container through the membranes so that the compound is dissolved.  Ammonium ions are emitted from the container by diffusion through the membrane.  The total area of the container aperture or apertures and the characteristics of the membrane are selected to control the release rate of ammonium ions for attracting aquatic animals to the vicinity of the container.  A screen encircling the membrane reinforces it.  A protective shroud may be spaced outward from the screen.  The container can be formed by fitting a water permeable membrane sleeve and a reinforcing screen over an oblong block of the ammonium ion-producing compound and then covering the opposite end portions of the block with liquid resin, such as polyurethane material, and allowing such resin to set such that only a circumferential slit of screen and membrane is exposed.

Abstract: ABSTRACT OF THE DISCLOSURE:           An improved gravitational separator for mixtures of immiscible liquids of different densities, particularly oil and water, includes a floatation force responsive member in the form of a dome or diaphragm immersed in more dense liquid to be separated and which floats upwardly in the more dense liquid under the influence of liquid of less density accumulated beneath the dome or diaphragm, and a precise, passive balance means for the force responsive member used to sense the accumu-lation of a predetermined volume of less dense liquid in the separator.  The balance means is a system of weight masses contained entirely in the separator that are raised by the upward movement of the force responsive member under the influence of accumulated less dense fluid, in combination with remote sensing means outside the separator for sensing the respective balance conditions and signalling appropriate system controls to cause suspension of the influx of mixture into the separator and discharge therefrom of accumulated lighter liquid.          A coalescer screen filter system is provided in the water out-let path in the separator, the coalescer screens being con-tained in a chamber provided with automatically operating check valves to ensure proper flow of water in a forward and backflush sense through the chamber.  The force responsive member may be provided with flexible seal means extending vertically in the separator for preventing the accumulation of lighter liquid above the reaction member, while not interfering with the operation of the balancing system of the force responsive member.

Abstract: "BARN SCRAPER DRIVE ASSEMBLY"         ABSTRACT         The drive motor is pivotally supported axially with-in the frame so that it rotates slightly if the torque of the motor increases due to the scraper assembly being impeded by animals, equipment, broken slats or the like.  This actuates a reversing switch thus reversing the movement of the scraper assembly.  If desired, an electric shock circuit can be in-cluded which is actuated first,  in   case the obstruction is an animal.  If the animal moves away from the scraper then the scraper proceeds as the reversing switch has not been actuated at this time.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a car which, when station-ary, serves to receive the carbonized coke from an oven chamber and is adapted to travel along a battery of coke ovens and be-neath the quenching tower.              Whereas the inclined loading surface of the hitherto frequently conventional inclined coke-cars is situated with its top end just beneath the oven platform over which the carbonized coke cake is pushed, and the bottom edge is situated above the top edge of the coke-side bench on to which the quenched coke is discharged and the car is moved longitudinally of the battery during the coke pushing operation, in order to distribute the load over the entire length of the inclined surface of the car, the new car is stationary during coke pushing.  It is a one-point coke-car.  The reception container is a square box of appropriate depth.  The car preferably travels on rails having the same track as the inclined cars used heretofore.  The con-tainer floor is pivotable about an axis extending in the direc-tion of travel of the car, pivoting being between two positions, i.e. a substantially horizontal position which, if required, may be inclined by about 5° to the horizontal, and in this position the floor forms the bottom closure for the box, and an inclined position in which its top surface substantially forms the top continuation of the coke-side bench surface.  The distance between the floor pivot axis and the coke-side bench is less than the distance between the axis and the oven platform.

The mainline cable is fastened to a cylindrical ferrule having an axial bore through which the end of the mainline cable passes.  The bore tapers inwardly away from the end of the cable and receives a pair of semi-cylindrical nubbins having a taper matching the taper of the bore.  The nubbins are positioned between the cable and the walls of the bore, and the wedging action of the nubbins with the mainline cable and the ferrule securely fastens the mainline cable to the ferrule yet allows the ferrule to be easily released from the cable.  A generally U-shaped shackle is rotatably secured to the ferrule by a pair of pins projecting diametrically from the ferrule into respective bores formed in opposite legs of the shackle.  One or more choker cables are fastened to the shackle by loops formed at the ends of the choker cables which surround the curved portion of the shackle.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of monitoring the performance of a steam power plant, wherein the monitoring is made through a calculation of the performance from detected data representing the states of operation of various parts of the plant, such as feedwater flow rate, steam pres-sure, steam temperature and the level of the load imposed on the plant.  The method has a function for judging the fluctuation of the load and a function for judging the duration of steady state of the load.  When the rate of fluctuation of the load is below a pre-determined reference and this state of load lasts over a predetermined time length, it is judged that the data detected during this time length are valid as the data for monitoring of the performance and the performance is calculated from these data to permit the monitoring.          Also, disclosed is an apparatus for monitoring the performance of a steam power plant of the type having detectors for detecting data representing the states of operation of various parts of the plant such as feedwater flow rate, steam pressure, steam temperature and the level of load imposed on the plant, and a plant performance calculation means for calculating the performance of the plant on the basis of the detected data.  The apparatus comprises a first comparator for comparing the rate of fluctuation of the load detected by the detector for detecting the load with a predetermined reference value, a second comparator for comparing the detection duration or time length of the detection obtained from the detector for detecting the load with a predeter-mined reference value, and judging means adapted to permit the detected data to be delivered to the plant performance calculation means for the calculation of the heat rate of the plant, in accordance with the outputs from the first and the second comparators, when the rate of fluctuation of the load is below the level of the reference value and this state of the load lasts over a predetermined time length.
