Abstract: ABSTRACT                    SWINGING LINX MECHANISM     A swinging link mechanism for connecting a prime mover to a rigid trailer comprises an upper and lower opposed pairs of laterally spaced mountings, the lower pair for attachment to the prime mover and the upper pair for connection to the trailer.  A swinging link pivotally connects each respective two opposed mountings.  The two links are inclined toward one another.  The spacing of the lower pair of mountings to be attached to the prime mover exceeds the spacing of the upper pair to be connected to the trailer.  The mechanism is particularly for semi-articulated tankers and allows for twisting of the semi-trailer relative to the prime mover.

Abstract: Abstract of the Disclosure A solution polymerization process for the prepara-tion of high molecular weight polymers of .alpha.-olefins selected from the group consisting of homopolymers of ethylene and copolymers of ethylene and C3 - C12 .alpha.-olefins is disclosed. The process comprises feeding monomer(s), coordination cata-lyst and inert hydrocarbon solvent to a reactor, polymerizing the monomer(s) at a temperature of up to 320°C and a pressure of less than 25 MPa, and deactivating the catalyst in the solution so obtained.  The catalyst is deactivated by sequen-tially admixing therewith a minor amount of water followed by a solution of a salt of an alkaline earth meta  or zinc and an aliphatic monocarboxylic acid dissolved in hydrocar-bon solvent.  The hydrocarbon solvent and other volatile matter are then separated from the resultant solution and a composition comprising said high molecular weight polymer is recovered.  The amount of water added is not more than 2.5 moles of water per mole of halogen plus alkyl radicals in the coordination catalyst.  In an embodiment the water has a water-soluble metal chelating agent dissolved therein.

A spout is positioned on the upper end of the post and is seated upon the base when the post is in the fully lowered position.  The spout is rotatably movable, as a unit, and is vertically adjustable.  The exterior of the post has recess means thereon and there is retaining means on the base to cooperate with the recess means to position the post, and spout in a vertically raised position relative to the base.          The spout is pressure balanced whereby back pressure therein caused by flow control devices on the spout will not cause un-desired vertical movement thereof.

Abstract: Abstract A mixing system and method for analyzing a specimen is provided which includes introducing a predetermined number of discrete jets of liquid reagent into a container carrying a specimen.  The jets of reagent cause turbulent mixing of the reagent and specimen.  The jets are time-spaced to allow settling of the mixture between jets to prevent the escape of the mixture from the container.  After the reagent and specimen are thoroughly mixed, a characteristic of the mixture is then detected.

Abstract: ABSTRACT OF THE DISCLOSURE     The most frequently-ordered items in an inventory of relatively small items such as fasteners, electronic parts, etc. are stored in both "A" and "B" sections of the warehouse. The "A" section is smaller than the "B" section, and usually contains smaller quantities of an item than the "s" section.          The "A" section is located as close as possible to a retrieval station so as to minimize retrieval time and distance.          Parts are stored in containers of standardized sizes, the "A" containers being open, the "B" containers being sealed.          The locations of incoming new items in the "B" section is random so as to maximize utilization of warehouse space.  A computer stores and updates the quantity of items in every container.  Retrieval is made solely from an "A" container if the quantity in it is sufficient.  If not, additional items are retrieved from one or more sealed containers in the "B" section.  When an "A" container is empty, a 'IB'' container is used to replace it.  Each movement of stock items into, within, and out of the warehouse is controlled by systems of labels, shelving and retrieval instructions, and inventory records generated by a computer.

Abstract: Case 3-13913/S/+     Process for the preparation of 1-diorganocarbamoyl-polyalkylpiperdines Abstract Compounds containing a group of the formula I            in which R is H or c1-c4-alkyl, R1 is H, CN, an acyloxy group or a free valency and R2 and R3 are organic radiclLs can be prepared in a simpLe manner from the corresponding compounds containing a group of the formula Ia   by stepwise reaction with phosgene and a secondary amine R2-NH-R3 in the presence of a molar amount of a base. The N-diorganocarbamoyl compounds containing the group I are outstanding light stabilisers, in particular for organic polymers.

Abstract: ATRIO-VENTRICULAR CARDIAC PACING CATHETER                 ABSTRACT OF THE DISCLOSURE   A cardiac pacing catheter system includes a main guiding catheter and a pair of electrical leads adapted to make direct electrical contact with the ventricle and the atrium of the patient's heart. The main catheter has a pair of lumens which guide and contain the ventricular and atrial leads.  Each of the leads can be advanced and manipulated separately and independently within the main catheter body.  The lumen for the ventricular lead exits at a port at the distal end of the main catheter body.  The lumen for the atrial lead exits along a port at the side of the catheter, at a location proximal of the distal end.  The atrial lead is spring-like and is formed with a J-shaped curve at its distal end which, when it exits from the catheter lumen, will assume the J-shaped configuration so that it may be manipulated into direct contact with the more upwardly disposed roof regions of the atrium.  In use the catheter is advanced, with the leads retracted, to the entry to the right atrium.  The ventricular lead then is extended to the ventricular apex and secured.  the atrial lead then is advanced, assumes its J-shaped configuration and is adjusted into position to contact the roof of the atrium.
