Abstract: ABSTRACT OF THE DISCLOSURE          A stator vane assembly is provided, particu-larly for the first row of stationary vanes of a gas turbine, utilizing ceramic vanes.  Each individual vane assembly consists of an airfoil vane with a separate end cap at each end for supporting the vane in position.  Each vane has an airfoil portion with a tenon portion at each end thereof having a curved surface for engagement in a recess in the adjacent end cap which has a similarly curved surface.  The tenons have a different cross-sectional con-figuration than the airfoil portions of the vane such that the area of contact between the tenons and the end caps is greater than the cross-sectional area of the airfoil por-tion and is preferably substantially coextensive with the surface of the recess in the end cap.  The tenons termi-nate short of the leading and trailing edges of the airfoil portion so that the tenons are not coextensive with the airfoil in either direction.

Abstract: Abstract of the Disclosure A container for photographic processing composition being releasably sealed by a novel seal provided by a flexible web releasably bonded to a plurality of lips surrounding an aperture in the container.  The novel seal is such that owing to its relatively small area of bonding between the web and the lips assures proper separation of the web from the lips when a pulling force is exerted on it.  On the other hand, the multiple seal formed by the bonding of the web to the plurality of lips is such that it withstands without rupture excessive internal pressure in the composition as may be arising from inadvertant shock forces.

Abstract: ABOVEGROUND ANCHOR SUPPORT ASSEMBLY FOR A PIPELINE           ABSTRACT         An anchor support for supporting a pipeline above the ground has a self-aligning support saddle that allows the pipeline to orient itself on the anchor support during construction to relieve stresses in the pipeline and to allow for variations from nominal pipeline elevation and angulation relative to the ground.          The anchor support normally fixes the pipeline's position relative to the ground but also allows relative movement between the support and the pipeline upon occurrence of a seismic disturbance or other disturbance that would cause a dislocation of the pipeline and/or anchor support from its nominal position.  The self-aligning support saddle, which includes a ball and socket connec-tion for allowing the pipeline to orient itself over the saddle, is fastened to a shiftable subassembly that rests on a stationary base assembly affixed to one or more ground engaging vertical support members.  After the pipeline is aligned, the ball and socket can be permanently interconnected to restrain any further movement of the pipeline relative to the shiftable subassembly.          The shiftable subassembly is capable of moving relative to the base assembly in a direction generally parallel to the longitudinal dimension of the pipeline.  When a differential force is applied between the vertical support members and the pipeline, as can be caused by a seismic disturbance, the shiftable subassembly can move along with the anchor saddle and the pipeline relative to the base assembly, thereby preventing any substantial damage to the pipeline.  A restraining mechanism interconnects the shiftable subassembly with the base assembly to releasably restrain the shiftable subassembly upon application of a differential force of less than a predetermined magnitude.  Upon application of a predetermined differential force, the restraining mechanism releases the shifitable subassembly so that it can move relative to the base assembly.  Once the shiftable subassembly has begun to move relative to the base assembly, the restraining mechanism still applies a differential force opposing the movement.  After the shiftable subassembly has moved a predetermined distance relative to the base assembly, an energy absorbing member deceler-ates and stops the shiftable subassembly to prevent it or the remainder of the anchor support from becoming damaged.

Abstract: COUNTING CIRCUITS FOR MULTIFREQUENCY TONE DETECTORS         Abstract of the Disclosure Intervals between zero crossings of tone signals on two incoming lines are measured by a clock driven, free running binary counter common to the two lines and by an overflow counter individual to each line.  The overflow counter is reset by the reception of the zero crossing of the tone signal and is then advanced by each overflow and recycle of the common counter.  The common count number, produced when the zero crossing at the start of the interval is received, is processed with the common count number and the overflow number, produced when the zero crossing at the end of the interval is received, to calculate the duration of the interval and thereby determine the frequency of the tone.
