Abstract: ASTRACT OF THE DISCLOSURE         A two-part barrel sleeve includes an internal spring finger which rides in a spiral groove in the combi-ned ink reservoir and barrel of a ball pen, the spiral groove having a detent at its rear end to provide a snap-action as the barrel sleeve is retracted to its rearmost position exposing the writing tip for normal use.            SPECIFICATION         The present invention relates in general to writing instruments of the type in which a tubular shroud may be moved between a forward storage postion wherein it covers and protects the writing tip of the instrument, and a rearward retracted position wherein the writing tip is exposed for normal use.     BACKGROUND OF THE INVENTION         It is known in the prior art to threadedly mount a tubular barrel to a writing cartridge located within the barrel so that relative rotation between the writing car-tridge and the barrel results in axial displacement of the barrel relative to the cartridge.  In that construction the writing tip may be shrouded by the barrel when the writing intrument is not being used.  See, for example, U.          S. patents 2,441,280 and 2,603,186 for a description of that type of writing instrument.  Similarly, it is known to threadedly attach a short, tubular shroud sleeve to the barrel of a writing instrument for the same purpose.           Although these prior art systems have functioned as intended, they have exhibited several characteristics

Abstract: ABSTRACT OF THE DISCLOSURE          Liquid piping saddle assemblies in few embodiments, all having significant interchangeable parts are available for con-necting branch pipes, i.e. laterals, to main pipes, i.e. mains.          Each assembly has only one gasket of elastomer which seals both the lateral and the main and which integrally comprises essentially two cylinders.  Each gasket of elastomer integrally includes a smaller hollow cylinder to snugly and sealably receive a lateral and a larger hollow cylinder to abut and to seal a main about the exterior of a hole made in the main of a diameter substantially matching the outside diameter of the lateral.  Each gasket has a transitional volume structure of the gasket between the integral smaller hollow cylinder and the larger hollow cylinder.  On the interior of this transitional volume structure is an integral interior circular abutment having an inner diameter substantially matching the inside diameter of the branch pipe, i.e. the lateral.  On the exterior of the transitional volume structure is an integral exterior abutment structure having an inside diameter to match the inside diameter of a hollow cylindrical metal casting and an outside diameter to match or exceed the outside diameter of the same hollow cylindrical metal casting.  Integral interior rings, semicircular in cross section, are formed in some gasket embodiments inside the smaller hollow cylinder to assist in sealing about the exterior of an inserted branch pipe, i.e. lateral, which is inserted until contacting the interior integral circular abutment.  The exterior of the smaller hollow cylinder has an outside diameter to match the inside diameter of a hollow cylindrical metal casting in all embodi-ments.  In some embodiments the thickness of the smaller hollow cylinder is reduced and an adjustable hose clamp is fitted to its exterior surface above the hollow cylindrical-metal casting.     Opposite sets of spaced, upwardly sloping, receiving ears are integrally cast with the hollow cylindrical metal casting.  Between these receiving ears, the threaded ends of bolts are received, and on the extending threads, beyond the ears, washers and nuts are positioned.  The bolt heads are different with one head having a tee bar welded to an adjustable length metal strap and another head having two spaced adjacent tee bars welded at their ends, with one of these spaced tee bars, the outer one, being welded to the other of the two threaded bolts.  The adjustable length metal strap is threadedly passed through the space between the spaced adjacent tee bars.  When a proper length is determined, the metal strap is bent back in the opposite direction over the spaced tee bar and directed back alongside the metal strap, which is to partially encircle the main pipe, while and after the tightening of the nuts occurs to complete the sealed connection of the saddle assembly to the branch and main pipes, i.e. to the lateral and main.

Abstract: Abstract of the Disclosure An aqueous flocculant solution containing a tannin based polymer compound is produced which is stable and has a shelf life of at least 3-6 months before gelling.  The solution is made by reacting at a temperature of from about 150°-200°F a tannin, an amino compound, and an aldehyde under slightly acidic conditions where the pH is less than 7 and where the molar ratio of the primary amine from the amino compound to the tannin repeating unit is from about 1.5:1 to 3.0:1.  The intermediate viscosity of the reaction mixture is monitored until the reaction mixture has an intermediate viscosity within the range of the system key intermediate viscosity range.  This system key intermediate viscosity range is previously determined for each reactant system to be employed.  It is a narrow intermediate viscosity range that is experimentally determined which permits the resulting product to have a long shelf life.  The narrow system key intermediate viscosity range will generally be within the range of from about 2-100 cps when measured at 180°F on a Brookfield LVT viscometer.  When this viscosity is reached, the reaction is terminated and the solids content of the liquid is adjusted to about 20 to 60% by weight and the pH is adjusted to a value of less than 3,0.

Abstract: ABSTRACT In a maskless metal cladding process for plating an existing metallurgical pattern,  a protective layer is utilized to isolate those areas of underlying metallurgy on which additional metal plating is not desired.  The layer  acts  as  an  isolation  barrier  to  protect  the underlying metallurgy  from deposition and  subsequent diffusion of the heavy metal overlay.  The composition of  the  protective  layer  is  selected  as one  having sufficient mechanical  integrity  to withstand process handling and support the gold overlay and having the thermal integrity to withstand the high temperatures reached during metal sputtering and diffusion processes. The isolation barrier layer has an organic component as a binder which thermally decomposes, either in a heating step before metal deposition or during the diffusion cycle,  leaving no carbonaceous residue but leaving an inert, inorganic standoff to support the metal.  After diffusion of the metal, the remaining inorganic standoff layer, overlying  metal and any undiffused metal remain-ing on the non-patterned substrate is easily removed by a standard technique, such as ultrasonics.

Abstract: INDUCTION FURNACE MONITOR ABSTRACT OF THE DISCLOSURE The specification discloses a computerized monitor for a coreless induction furnace.  The monitor includes a first potential transformer connected across the coil and a second potential transformer connected between one end of the coil and an electric ground.  The relative location of a ground fault along the length of the coil is determined by computing the ratio of the transformer outputs.  The monitor further includes a first current transformer in the coil power line and a second current transformer in the melt bath ground.  Internal ground faults are detected by computing the phase difference between the coil and ground currents. A graphic representation of the furnace is also generated to illustrate the location of the ground fault with respect to turns and yokes of the coil.  The monitor also calculates liner wear by determining melt bath volume, which is inversely proportional to melt bath resistance, which in turn is pro-portional to coil resistance.  If the furnace being monitored is provided with more than one coil, a differential current transformer is connected across each coil to detect the fault grounded coil when the transformer associated with the faulted coil exhibits a substantially nonzero output.
