Farbenfabriken Bayer had become part of a trust, I.G. Farben, a combination of several dye firms that suffered under the harsh provisions of the Treaty of Versailles that ended the war. Farbenfabriken scientists sought other uses for acetylene. I.G. Farbenfabriken possessed the Haber Process for the synthesis of ammonia from nitrogen and hydrogen. In 1938 Paul Reppe synthesized N-2- vinylpyrrolidone from acetylene and ammonia SCC SW CHAPTER 1118 Polymers in Cosmetics 36. Farbenfabriken formed two New York corporations in 1913, Synthetic Patents Company, Inc., and The Bayer Company, Inc. Defendant, Sterling Drugs, Inc., a Delaware corporation, is, like plaintiff.

What is claimed as new is as follows
1. For detachable and adjustable use on and in conjunction with a conventional tapered nozzle type torch tip, a tip supporting, positioning and flame focusing guide comprising an adapter structurally designed and adapted to be adjustably but operatively mounted on said torch tip, a rigid leg which is adapted to be moved alongside of and in conjunction with said torch tip and having upper and lower ends, a work surface contacting wheel mounted for free rotation on the lower end of said leg, and a link interposed between said leg and adapter, said link having an outer end pivotally operatively joined to the upper end of said leg and an inner end pivotally operatively joined to a coacting surface portion of said adapter, said adapter comprising a collar-like band having separably connectible band mounting and adjusting ends, said surface portion having a rigid radially projecting lug, the inner end of said link having a terminal fork, the arms of said fork straddling and being pivotally but retentively joined to said lug.
2. The flame focusing guide defined in and according to claim 1, and wherein the upper end of said leg is bifurcated, the outer end of said link terminating and being disposed between and pivotally and clampingly joined to the respectively encompassing bifurcations.
3. The flame focusing guide defined in and according to claim 1, and wherein the upper end of said leg is bifurcated, the outer end of said link terminating and being disposed between and pivotally and clampingly joined to the respectively encompassing bifurcations, the lower end of said leg also being bifurcated and said bifurcations being provided with a complemental axle, and said wheel being journalled for free rotation on said axle and being confined for operation between said bifurcations.
4. A self-contained nozzle type torch tip supporting, adjusting, positioning and flame focusing guide for attachment to said tip comprising: an adapter embodying a collar-like band which is adapted to encompass a selected portion of said tip, said band having overlapping adjustably connectible ends, one end portion having transverse longitudinally spaced adjusting slots, the other end portion having band-end connecting and adjusting means, a median portion of said band being provided with an outstanding ear-like lug, a rigid leg adapted to be located and moved alongside of and in conjunction with said torch tip and having upper and lower ends, work surface contacting wheel mounted for free rotation on the lower end of said leg, and a link interposed between said leg and adapter, said link having an outer end pivotally operatively joined to the upper end of said leg and an inner end pivotally operatively joined to a coacting surface portion of said adapter.
5. The self-contained nozzle type torch tip supporting, adjusting and positioning guide attachment according to claim 4 and wherein the three connectible ends of said band are provided with a complemental sleeve, said sleeve providing a socket member and being internally screw threaded, an adjusting member having a shank which is threaded into the threads provided therefor in said sleeve and as provided with an adjusting head at an accessible end, the threads of said shank being cooperable with the aforementioned adjusting slots for purposes of connecting and adjusting the effective diameter of said band.
6. The self-contained nozzle type torch tip guide attachment defined in and according to claim 5 and wherein the upper end of said leg is bifurcated, the outer end of said link terminating and being disposed between and pivotally and clampingly joined to the respectively encompassing bifurcations, the lower end of said leg being also bifurcated, said bifurcations being provided with a complemental axle, and said wheel being journalled for free rotation on said axle and confined for operation between the coacting bifurcations.
7. The self-contained nozzle type torch tip attachment defined in and according to claim 6 and wherein the inner end of said link has a terminal fork, the arms of said fork straddling and being pivotally joined to said lug.
