Abstract: ABSTRACT OF THE DISCLOSURE     An  improved  slip-type  elevator  locking  mechanism has a lock rod which has one end connected to the slip setting yoke and a free end extending generally parallel with  the  direction of  movement  of  the  slips  in  the elevator bowl.   A cam arm mounted on the elevator at a central pivot point has a cam throat on one end which is adapted to receive the lock rod free end and an opposite end and is pivotable about the central pivot point between upper and lower lock rod engaging positions and a neutral, unlocked position.  A fluid cylinder is pivotally mounted by a base end to the elevator and is pivotally attached at its output shaft to the cam arm opposite end for urging the cam arm to the neutral position.  The fluid cylinder output shaft is spring-biased outwardly away from the base end in the absence of fluid pressure on the cylinder.  A yoke rod has one end connected to the slip-setting yoke and a free end extending in a direction generally parallel to the lock rod in a plane which intersects the plane of the cam arm opposite end.  Upper and lower coil springs on the yoke rod urge the cam arm toward a select one of the upper and lower lock rod engaging positions when fluid pressure is lost.

Abstract: New devices and kits for immunological analysis Abstract The invention relates to new devices and kits for immuno-assays, especially solid-phase immuno-assays, comprising a solid porous support, preferably in the form of a sheet, where antigens or immuno-globulins, or both of them, are bound by direct application, with no other chemical or electrochemical treatment. The use of such supports makes possible to effect an unlimited number of antibody-antigen reactions simultaneously and in one operation. The assays with these new kits are technically extremely simple in practice. The antigens or immunoglobulins on the solid support can be applied in any suitable pre-selected geometry, e.g. as an array of dots, preferably micro-dots, or lines. A preferred material for the solid support is nitrocellulose or nitrocellulose mixed with other cellulose esters.            Before carrying out the immuno-assays residual adsorbing sites on the support must be saturated with whole serum of heterologous species to prevent non-specific binding. The invention is also directed in particular to devices and kits treated in this manner, and, if desired, washed and dried. They can be stored for an inde-finite time without loss of activity.        In the immuno-assays to be carried out according to the present-invention the preferred detection system is the use of anti-primary species antibody coupled to peroxidase with a chromogenic substrate.          The color intensity can be quantitated and calibrated with standards of known amounts of immunoglobulins bound to the same support.          Densitometry permits the evaluation of the color reaction over a 1000-fold range of concentrations.            The new kits can also be used with specific antibodies in a pre-determined array on the solid support for the detection of specific antigens and with complement proteins to detect antigen-antibody complexes.

Abstract: ABSTRACT OF DISCLOSURE     A dryer fabric and method for drying a web W of paper material is disclosed which includes passing the web through a dryer having a plurality of heated cylinders and holding the web in contact against the heated cylinders by means of a dryer fabric 24 arranged as an endless traveling dryer fabric.  The dryer fabric includes a plurality of elongated helix means 30 extending in a cross-wise direction constructed from a polymeric material characterized by stress-and heat resistance to which said fabric is subjected during endless travel about the rollers at elevated drying temperatures.  Joint means 32 joins adjacent ones of helix means successively together in a machine direction to form an endless belt of desired dimension.  Spaced upper and lower generally parallel loop runs 34a and 34b in the helix means 30 define a smooth generally flat paper contacting surface.  An open mesh 36 is defined in the fabric between adjacent joint means and runs of loops 34 along the cross-wise and machine directions of the fabric through which heated vapor and the like flow and are transferred outwardly from the paper web.          Polymeric filler strands are inserted across the helix means closing the mesh to reduce flow.  The edges of the fabric are heat sealed retaining the filler strands and helix means as integral fabric structure.  In one embodiment, the filler strand includes low-melt nylon strands 42 which are heated to expand and occupy the helix strips more completely and which interlock the upper and lower loop runs providing a more stable fabric structure.

Abstract: ABSTRACT OF THE DISCLOSURE A tension member is secured at each end to a separate anchoring system for transferring the tensile force from the member to a support structure.  The tension member is made up of individual elements disposed in parallel over an axial length located between the ends.  After the individual elements are tensioned, open spaces around the elements within the tubular casing are filled with cement grout.  Between the tubular casing and each anchoring disc the individual elements extend through and are guided within an anchoring pipe. One end of each anchoring pipe bears against the associated anchoring disc and supports the anchoring disc. A radially outwardly and inwardly projecting annular collar is formed in the anchoring pipe and the collar forms an outwardly extending annular shoulder for transferring the load from the anchoring disc to the support structure.  Since the collar is spaced from the anchoring disc, the stress developed due to live loads in the tension member in the axially extending region between the collar and the anchoring disc, is reduced at least in part due to the compressive forces which prevail in this region of the anchoring pipe.  Accordingly, alternating stresses caused by live loads do not reach the location where the individual elements are secured to the anchoring disc.  Such an arrangement improves the fatigue strength of the tension member.

Abstract: Abstract:     Methods and compositions for treating inflammation or arthritis A method of treating inflammation or arthritis with metal complexes that can traverse skin and animal cell membranes intact and effectively deliver and release metal ions in a controlled manner upon demand at the targeted inflammatory or arthritic areas containing endogenous reacting moieties which demand the metal ions.  The metal complexes have an aqueous proton induced dissociation property represented by a sigmoidally-shaped curve on a cartesian coordinate plot of the negative log of the metal ion concentration versus the negative log of hydrogen ion concentration.  This dissociation property enables the metal complexes to release metal ions in a controlled manner upon demand at the targeted inflammatory or arthritic areas containing endogenous reacting moieties which demand the metal ions.  The metal complexes can be effectively administered either topically or subcutaneously.  Upon topical application, the metal complexes are dispersed in a vehicle to provide a buffered composition to neutralize the initial acidic layer of the skin.          These unique and advantageous properties permit the metal complexes to be incorporated into vehicles with an adjusted pH minimizing premature release of the metal ions prior to reaching the targeted inflammatory or arthritic areas.  Further, the metal complexes can be dispersed in a greaseless cold cream vehicle formulated to avoid or minimize undesirable chemical incompatibilities.  An example of a topical composition employed is disodiummonocopper(II) citrate in an amount of about 10% w/w in a water-dispersable cream base vehicle comprising an oil-in-water emulsion having a pH of about 7Ø
