Abstract: ABSTRACT OF THE DISCLOSURE           A method for the controlled bending of a submerged pipeline is disclosed.  The section of the pipeline which is to be bent is slightly elevated off the sea floor, preferably by buoys attached to the pipeline along its length.  The end of the elevated section of pipeline is pulled in to the desired point of termination while a drag force is simultaneously applied to the elevated portion of the pipeline.  The applied drag force should be sufficient to create a bending moment which causes the pipeline to bend along a well defined arc.  Preferably, dragging means such as chains, cables, or clump weights extending from the pipeline to the sea floor are used to impose the necessary drag force on the pipeline and to control elevation of the pipeline above the sea floor.

Abstract: ABSTRACT           An adjustable link assembly for transmitting loads in opposite directions is disclosed.  The assembly includes a socket and a shank.  The socket has an internally threaded bore and the shank has an externally threaded portion threadably engaged in the internally threaded bore, the threaded connection transmitting loads axially in opposite directions between the socket and the shank.  The shank and the socket are relatively rotatable to vary the overall length of the link assembly,  A predetermined minimum length of threaded contact is maintained between the shank and socket through which the loads may be transmitted, a spring member being carried by the socket and movable into engagement with the shank to prevent a decrease in the length of contact between the threads on the shank and socket below that pre-determined minimum.

Abstract: IMPROVED SPINDLE CONTROL MECHANISM            Abstract of the Disclosure An improved spindle control mechanism for a lathe that includes, in preferred form, a rotatable control knob operably related to a plurality of spindle motor control and servo-control switches by a switch drum fixed thereto and operably connected to a spindle transmission through a control shaft by a connector link pivoted in an eccentric position at one end to the control knob and pivoted at the other end to a lever arm fixed to the control shaft.  Rotation of the control knob into a forward position simultaneously translates the lathe's transmission into a forward spindle rotation position and starts the spindle drive motor.  Rotation of the control knob into an intermediate stop position simultaneously stops the spindle drive motor and acti-vates the spindle servo-control switch (which permits the spindle's rotation speed to be changed by a separate spindle servo-control mechanism, if desired).  Rotation of the control knob into a reverse position simultaneously translates the transmission into a reserve spindle rotation position and starts the spindle drive motor.

Abstract: ABSTRACT OF THE DISCLOSURE            The specification discloses a method and apparatus for accurately positioning a lid of a series of lids above a container flange in preparation for the heat sealing operation.          The appratus is designed to maintain the production rate of prior art filling and packaging machines while still pre-cisely locating a lid such that little or no overhang of the lid relative to the flange of a container occurs. This is achieved by providing a start and stop type conveyor with individual conveyor plates provided with alignment lugs for urging the flange of a container and a lid into alignment.          The resulting product is less vulnerable to lid damage and hence is more presentable when served to the consumer.  This system is particular valuable in the packaging of individual creamer containers.

The polymeric materials are comminuted at cryogenic temperatures and are then introduced into a liquid vehicle preferably while still at or near cryogenic temperature.  At low concentrations, the resulting blend or system displays reduced friction to flow while high concentrations may be used to immobilize the liquid vehicle and/or reduce its vapor pressure.

Abstract: TITLE OF THE INVENTION    High Concentration Polymer Slurries.          ABSTRACT OF THE INVENTION:      High concentration polymer slurries contain up to 60 weight % to 75 weight % xanthan gum in a solvent base treated with suspending agents, dispersants, and thinning agents.  Mineral oil, diesel oil, kerosene, alcohols (six to twelve carbons), vegetable oil, ester-alcohols, polyol ethers, and the like may be used as the solvent.  The preferred suspending agent is either an organophilic clay or hydroxypropyl cellulose. The preferred dispersant is either an ethoxylated linear alcohol or a fatty acid ester of vegetable oil or animal oil.  The preferred thinning agent is lecithin.  These slurries greatly improve the dispersibility of xanthan gum or any other hydro-philic colloid, such as guar, hydroxypropyl guar, cellulosics, polyacrylamides, and the like.

Abstract: ABSTRACT OF THE DISCLOSURE        A solvent recovery system is disclosed with at least two adsorbers and a condenser.  A first gas which is enriched with solvent vapor is guided for adsorbtion over the first ad-sorber.  Simultaneously, a second gas is guided for the pickup of solvent vapor which has been released by the second adsorber previously charged with solvent vapor so as to discharge it while being heated.  The second gas which is charged with sol-vent vapor is guided over the condenser in which the solvent precipitates out of the second gas.  Following this, the second gas which for the most part is free of solvent is guided add-itionally over the first adsorber in order to attain a complete cleaning of the gas.  After charging of the first adsorber the first gas is switched over to the second adsorber and the first adsorber is discharged.  The switchover proceeds with the help of a multi-path valve which can connect an input conduit with the first adsorber and the second adsorber.  Additionally, the multi-path valve for the discharging of the adsorbers can con-nect with the condenser.  As gas, air is used both for the charging and discharging of the adsorbers.

Abstract: CONCAVE SAFETY DOOR WITH SEALING AND           LATCHING FEATURES                  ABSTRACT OF THE DISCLOSURE A pivoted safety door for a harvester is disposed ahead of the concave and has a separately pivoted lip which normally rests on a front edge of the concave.  An adjustably biased detent mechanism releases the lip, permitting it to pivot out of engagement with the concave, when a rock or the like of substantial size attempts to enter the threshing chamber and is engaged by the threshing rotor.  A first manual control is provided for pivoting the main body of the door from its tripped position to a closed position.  A second manual control is provided for pivoting the lip relative to the door to restore it to its detented position, this last mentioned function being effected after the main body of the door has been restored to a closed position. The detent mechanism for the lip includes a pair of adjustably loaded spring biased plungers which act on opposite sides of a detented part.  The laterally opposite ends of the safety door are sealed in relation to vertical walls of the harvester by a pair of special seal structures which are pivoted to the harvester coaxially with the main body of the safety door.  The seal structures each include a rigid longitudinal sealing member in overlapping relation to one end of main body of the safety door with a free end loosely connecting with the leading edge of the concave and includes a flexible sealing element in engage-ment with the adjacent vertical wall.  The rear ends of the seal structures and safety door rest on and move up and down with the front of the concave when the latter is adjusted to change the clearance between the concave and the threshing rotor.  The seal structures also serve as stops to limit upward swinging movement of the safety door at the time it is closed to its operating position.

A mixing circuit mixes the video signal with the outputs of the clipping and slicing circuits, thereby to provide a vertical aperture-corrected output video signal which is substantially free of periodic fluctuations that might be present in the amplitude of the original video signal.          A preferred use of this vertical aperture correction circuit is with a color image pickup device of the type which generates a video signal having a superimposed periodic, fluctuating index signal thereon that produces a line-crawling effect in the ultimately produced video picture.
