Abstract: ABSTRACT OF THE DISCLOSURE A dry-break coupler, of the type used on a gaso-line tank truck loading arm, is connectable with a standard A.P.I. adapter, that is located near the bottom of a truck tank, for loading fluid into the tank,  The coupler and the adapter can be connected together or they can be separated, without the loss of fluid, while both fittings are continuously subjected to internal fluid pressure.  The coupler has a tubular body that defines a central flow passage.  Located within the tubular body is a movable valve closure element.  This element opens and closes the flow passage of the coupler, and is also actu-ates a central valve of an adjacent adapter.  An adapter latch and a first rotatable shaft that operates the adapter latch are pivotally mounted on the tubular body.          A second rotatable shaft that operates the valve closure element is mounted within the tubular body.  Portions of both the first and second rotatable shafts extend in sub-stantially parallel relationship.  Mounted on the shafts is a shaft interlocking mechanism that prevents rotation of the second rotatable shaft, to open the flow passage to the adapter, without first moving the adapter latch to a locked position.  The shaft interlocking mechanism also prevents rotation of the first rotatable shaft, to release the adapter latch from the adapter, when the valve closure element is in a position with the flow passage open.                               -la-

Abstract: ABSTRACT              Adhesive products such as label stock, labels, tapes and the like having an adhesive layer and a removable fibrous backing are described.  The backing is provided with integral embrittled zones which crack when the adhesive product is flexed and offer gripping points for removal of the backing.  The embrittled zones contain brittle, film forming organic polymer suffused among the fibers.  The presence of the polymer in the embrittled zone helps to enhance the brittleness of the zones and to reduce the transfer of residual chemical embrittling agent from embrittled zones of the backing to portions of the facestock brought into contact therewith when the adhesive product is stacked or rolled.  Embrittled zones are preferably formed by applying a thickened acidic solution comprising a polymer emulsion to the backing of the adhesive product and then curing and drying the solution by heating.
