Abstract: Abstract of the disclosure An apparatus and a process for detecting an absolute value relating to mechanical movement of a member to be measured from a reference point. The apparatus includes a detecting means with a plurality of detectors of which periods are different from each other. Each detector generates electric signal with its each period corresponding to movement of the member. The signals are stored in a memory. Then, absolute value of mechanical movement between one of detectors and the member is specified by using of two values. The one is equal to values of multiplication between the period of the signal corresponding  to  the detector  and an  integer.  The other is the stored value in the memory corresponding to the detector.   The value of the  integer  is decided by using periods and stored values corresponding to other detectors.

Abstract: ABSTRACT After an oil or gas test has been performed in an exploration well, the well fluid between the bottom of the drill pipe and the surface valve must be removed.  The process that is followed is to pump mud down the annulus below the rams and through a circulatory valve opened between the drill pipe and annulus for that purpose, forcing any well fluid in the drill pipe above that valve to the surface.  This well fluid must all be forced out of the drill pipe, including the fluid below the circulation valve, and therefore, the drill pipe must be raised out of the packer to accomplish this. However, even while the drill pipe is in this raised position, pressure must be maintained on the annulus below the rams.  The present invention ensures that this pressure is maintained by providing a hang-off tool which is fitted on the drill pipe.  The hang-off tool provides an effective sealing surface around which the rams can close.  An internal porting system is contained in the hang-off tool, which allows chemicals to flow from the surface to a chemical injection valve located beneath the ocean floor.

Abstract: ABSTRACT OF THE DISCOLSURE          A method for bringing a digester up to cooking temperature efficiently and rapidly wherein wood chips are packed in the digester, covered with a hot spent liquor, and then a hot liquor displacing liquid is used to displace the hot spent liquor from the digester and send it to an alkali adjustment zone in an accumulator.  After the hot spent liquor has been displaced, the hot liquor displacing liquid is passed through the digester and into a lower portion of the alkali adjustment zone.  Hot liquor is constantly passed from a constant volume heating zone into the alkali adjustment zone by overflow or otherwise.  Hot liquor at the cooking temperature is passed from the top of the heating zone into the bottom of the digester and relatively cool liquor after passage through the digester passes from the top of the digester to the bottom of the heating zone.  This type of circulation is continued until liquor leaving the top of the digester is at the cooking temperature whereupon the circulation is terminated and the heat content of the liquor in the heating section is increased by passage through a separate heat exchanger.

Abstract: TITLE:  SOD HARVESTER AND METHOD                 ABSTRACT OF THE DISCLOSURE         A sod harvester in which sod is cut, conveyed upwardly, and then travels downwardly over a floppy con-veyor and falls into a roll forming enclosure formed by a bottom conveyor and a vertical conveyor.  The floppy con-veyor swings downwardly at the start of roll forming, to reduce the free fall of the sod, and swings upwardly as the roll grows.  When the roll is formed, the bottom con-veyor is unlatched and tilts downwardly to discharge the roll, at the  same time pulling into cocked position a core tube injector arm.   When the roll discharges,  the bottom conveyor snaps upwardly, releasing the core tube injector arm which injects a fresh core tube  into the roll forming enclosure.  The sod is rolled with its grass side outwardly to facilitate laying and to protect the grass roots.  A tray on a cart at the end of the harvest-er receives the discharged  roll  and  can  convey  it  to either side of the cart.   When the tray reaches either side of the cart, a cam tilts the tray to discharge the roll onto the ground clear of the next pass of the har-vester.
