Abstract: Abstract of the Disclosure A method and apparatus are disclosed for producing randomly slubbed textile yarns.  The method involves passing the yarn through a zone of fluid turbulence having a pair of counterdirectional fluid streams maintained under different fluid pressures. The yarn passing between these counterdirectional fluid streams is alternately treated in opposing directions, with slubs being formed at the null points between the opposite directional treatments.  Due to the uneven fluid pressures employed, the length of treatment in each direction   along the yarn is not consistent, thus leading to slubs at various points along the length of the yarn.  A fluid jet is also disclosed for accomplishing this result.  The fluid jet includes a pair of interconnected and overlapping passageways having one or more fluid inlets arranged to direct fluid circumferentially around it and with the fluid streams being counterdirectional to one another.  The fluid inlets for each passageway are fed fluid at uneven or different fluid pressures to accomplish the random slubbing effect.

Abstract: ABSTRACT OF THE DISCLOSURE            An electromagnetic flow meter construction for substantially flush mounting within a surface past which a fluid is to flow.  A pair of spaced electrodes in contact with the fluid are mounted along a line perpendicular to the fluid flow and an elongated electromagnet provides magnetic lines of force substantially perpendicular to both the fluid flow and the line of the electrodes to generate an electri-cal potential between the electrodes proportional to the fluid velocity.  The electrode leads are oriented with respect to the electromagnet to minimize the guadrature voltage and the electromagnet is bifilar wound and utilized in a push-pull aternating current driving circuit.  The electrode signals are applied to synchronous detector to generate a direct current voltage proportional to the fluid velocity.

Abstract: ABSTRACT OF THE DISCLOSURE A long life railroad track and tie arrangement and method of making same. A wooden railroad tie is impregnated and covered with a thin layer of polypropylene which serves to protect the tie both from the weather and from mechanical abuse. The tie is apertured to receive rail mounting hardware. A bottom plate is secured to the underside of the tie and carries threaded fastening means mating the tie apertures. A top plate overlies the tie, carries a channel for receiving the rail, and is apertured to mate the tie apertures. A pair of apertured clips have extended arms overlying the prepositioned rail. Bolts are passed through the clips, the top plate, the tie and into the fasteners in the bottom plate to reliably secure the rail to the tie. In addition to its application in conventional track laying or track repairing situations, the invention allows manufacture of track in transportable prefabricated track and tie sections, which may be positioned and joined on site by simply welding adjacent rails.

Title: Method and apparatus for acoustically investigating  a casing and casing cement bond in borehole  penetrating an earth formation
Inventor: HAVIRA R MARK
IPC: G01N29/11
Filed: 1978-07-10
Granted: 1982-08-03
Abstract: ABSTRACT          Methods and apparatuses for acoustically investigating a casing in a borehole to derive the quality of a cement bond behind the casing and casing thickness are described. The techniques employ an acoustic pulse source having a frequency spectrum selected to stimulate selected radial segment of the casing into a thickness resource.  The selected frequency spectrum enhances the reverberations between the inner and outer with significant amplitudes for a duration depending upon the amount of acoustic energy leaked into adjacent media.    The acoustic pulse causes acoustic returns which are formed by the reflections from interfaces between media of different acoustic impendence and acoustic energy leaked into the bore of the casing from the acoustic thickness reverberations stimulated within the casing walls. The acoustic returns are detected to generate a reflection signal which is processed to determine casing thickness or to evaluate the cement bond.  The acoustic pulse has a frequency spectrum which is particu-larly effective in discriminating different cement bond condi-tions caused by small cement separations known as micro-annuli, around the casing. Several signal processing techniques and tools are described to provide accurate and high resolution cement bond evaluation and casing thickness determination by processing a portion of the reflection signal representative of the thickness reverberations.

Abstract: TITLE          LOAD BOOSTER WHEEL ASSEMBLY ABSTRACT OF THE DISCLOSURE          The rear end of the truck frame (generally an auxiliary frame which is mounted for fore and aft movement relative to the main truck frame) carries a load boosting rear wheel assembly.  The wheels are mounted on a transverse axle which is supported by a forwardly extending wishbone, the front of which has a ball and socket connection to a depending support bracket.  The rear portion of the wishbone is guided for vertical movement between the load carrying position which is the downward position of the rear axle and an elevated position in which the wheels are raised to an inoperative position generally employed in off highway operations.  The wishbone and, therefore, the wheels are actuated to the downward position by air pressure applied inside of the air bag assembly mounted between a plate carried by the wishbone and a plate carried by the frame.  In order to obtain a very large motion of the rear wheel assembly, the air bag assembly is sub-stantially longer than those customarily employed in the past and the midsection of the air bag assembly is provided with a rigid annulus which, in turn, is guided or constrained to linear motion, thus obviating the tendency of the air bag to go "out of column".  The wishbone is bent adjacent the ball and socket connection so that the axle is raised relative to the ball and socket.  When the rear wheels are in the operating or load carrying position, the end plates of the air bag assembly are substantially parallel to help insure that the bag remains in column when under load.  This is achieved by canting the upper end plate to match the bend of the wishbone to bring the plates into the parallel relationship.  Since only one air bag is used, the loading on the wheels will remain equal as the wheels pass over uneven terrain.

Abstract: ABSTRACT     A liquid level gauge for a tank, especially a pressurized railway tank car, has a housing with a bottom opening mounted at a top opening of the tank. A horizontal shaft is rotatably mounted in the housing between opposed walls having parallel flat vertical inner sur-faces. A sprocket is fixedly mounted on the central part of the shaft, on each end of which is fixedly mounted a ring magnet spaced from one of these walls. Complementary ring magnets are rotatably mounted outside but adjacent these opposed walls. The four ring magnets constitute a pair of magnetic drives. A track and cable guide assembly, supported in the tank, extends from the bottom portion of the tank.  A perforated tape is trained over the sprocket on the shaft and another sprocket rotatably mounted in the bottom portion of the tank so that the tape is under tension. A probe assembly connected to the tape moves vertically when the sprocket in the housing is rotated. The probe assembly senses a liquid-vapor inter-face and rides in the track and cable guide assembly. An electric cable connected to the probe extends up to the housing. Pulleys and cables keep the electrical cable under tension. One magnetic drive is rotated to move the tape and operate the other magnetic drive that has its complementary ring magnet connected to a device to indicate the position of the probe.
