Abstract: Abstract of the Disclosure A versatile process is presented for producing, in high yields, many different grades of pulp from a single wood specie or for pulping any specie or type of woody material. The process of this invention is virtually pollution free in that it pulps without a cooking liquor of harsh chemicals, and the reactant chemicals are easily recoverable from the by-products.          In the alternative, the by-products themselves have a commercial value which may forestall recovery of the reactants.  The lignin constituent extracted from the pulp is usable as a resin binder, a wood rehardening agent, or a glue. In this process the lignin is deploymerized without substantial migration from the cellulosic fibers. Depolymerization or digestion of the wood chips is achieved by exposure initially to ammonia and sulfur dioxide for from 10 to 60 minutes depending on the pulp grade desired under controlled pressure and temperature conditions, and subsequently to sulfur dioxide from 10 to 60 minutes also under controlled conditions of temperature and pressure in a digestor vapor dome adapted to suspend a chip mass in the reactant gases. The digested chips are then defibrated in a lignin dissolving solution of monoethanolamine to extract the lignin constituent. Because the reactant chemicals attack the lignin bonds without substantial damage to the .alpha. or hemi-cellulose fractions, a new fiber pulp is produced having properties superior to Sulfite process pulp yet nearly equivalent to Sulfate process pulp in strength.

Abstract: ALIGNMENT OF BYTES IN A DIGITAL DATA BIT STREAM            Abstract of the Disclosure A sequence of data bytes, which includes a low signaling rate control signal inserted in the framing bit position of each byte, is prepared for transmission by scrambling the information bits while maintaining the framing bit position unscrambled.  Pairs of bits occupying a corresponding bit position in different bytes are compared at the receiver and comparison mismatches are counted.  The framing bit position is identified by bits having a rate of change in their binary condition which does not exceed a predetermined count rate which is in excess of the low signaling rate of the control signal and is less than the anticipated rate of change of the scrambled information bits.  The receiver, when aligned with the framing bit position, is enabled to recover the control signal and unscramble the information bits.

Abstract: ABSTRACT OF DISCLOSURE        A crane which is admirably suited for shipboard use essentially removes the danger of a swinging block or a swing-ing load, and provides a simplified boom construction.  The boom is a three-part articulated boom with both of the forward parts swinging downwardly from the fully extended horizontal position.  In one form a winching means is preferably carried entirely by the outermost boom section.  Preferably there are two hoist lines, each with its own winching means which may be of drum or cylinder type.  In use of this form, the boom will be operated to place its tip at or only slightly above the load to be lifted so that the swinging of the hook hanging from it will be negligible even when swells cause movement of the ship.    Once the hook or hooks have been secured to the load, the line or lines may be winched in for snugness and the load lifted and moved to deck or hatch position with virtually no swinging.          With another form of the invention, a lift fork is carried at the end of the boom.  Because the extent of angular swing ex-cludes the use of the ordinary cylinder-leveling of the lift fork, it is hung on a pivot.  The necessary control for thrust-ing under a load is achieved by applying a disc brake to the pivoting action.

Abstract: ABSTRACT        A slotted plate terminal has a first slot portion with parallel sides which axe spaced by a distance less than the sum of the diameters of two wires to be connected by means of the terminal and exceeding the diameter of either wire, and two second slot portions which diverge away from the first slot portion and each of which is of smaller width than the diameter of either of the two wires.  When positioned in the first portion of the slot, the wires are necessarily at different levels.          When the wires are forced towards the second slot portions the leading wire moves into one of the second slot portions and also serves to cam the trailing wire into the other of the two second slot portions.  An electrical connector which utilises such terminals for the connection of multi-wire flat cable is also disclosed.

Abstract: DIAGNOSTIC IMMUNOCHEMICAL TEST     MATERIALS AND PROCEDURE              ABSTRACT OF THE DISCLOSURE       Materials and procedure are disclosed for conducting a rapid diagnostic test for the detection of an immunochem-ically reactive substance.  The test is suitable for detection of a specific antigen or antibody in serum or other bodily fluid.  A substance capable of immunochemically reacting with the substance to be detected is immobilized on an insoluble carrier.  The immobilized substance is used to harvest the substance to be detected from the bodily fluid.          The presence of the harvested substance is detected by the use of an antibody-enzyme conjugate capable of immunochemically binding the harvested substance.  The immunochemically bound enzyme activity provides a direct measure of the amount of the harvested substance.  Proper choice of carrier for the immobilized substance, method of immobilization, reagents and method of conducting the reaction sequence results in a rapid, sensitive, convenient and inexpensive technique, especially useful for detecting antibodies to Toxoplasma gondii and antigens of viruses, such as Hepatitis B.

Abstract: ABSTRACT           This invention relates generally to radiant beam focusing arrangements.  Many prior art systems depend upon mechanical moving parts between the objective lens and the information detector.  Such systems introduce delays which may materially affect the response time and other desired effici-encies in the movement of whatever element which will re-estab-lish the desired focus.  Also, many such focusing systems are very sensitive to tracking errors.  The present invention over-comes these difficulties by providing an optical transducer having concentric radiant beam detectors for converting a radiant beam to electrical signals including a first axially placed detector with a second detector concentric therewith, in one embodiment, the detectors receive the radiant beam through an amplifying auxiliary lens.  Changes in focus differentially affect the magnitude of the beam impinging on the individual de-tectors, resulting in corresponding changes in the individual detector outputs.  A focusing system employing the transducer moves a focusing lens in response to the differential output of the individual detectors.  An electrical difference circuit leading from the photo-detectors generates a driving signal to energize a lens-moving motor for shifting the focusing lens along the axis of the beam.
