✦ Synopsis

A heat-e †ective "integratedÏ process carried out in one reactor, composed of exothermic oxidative coupling of over the catalyst Ðxed bed and CH 4 endothermic pyrolysis of naphtha injected from the outside to the stream of gaseous coupling products in the hot oxygen-free postcatalytic zone, has been studied. An additivity of the yields of ethylene formed in both component processes was examined under varied operating conditions (type of naphtha fraction, Ñow rate of reagents and temperature of pyrolysis). A very high degree of additivity of the yields of ethylene and its main coproducts was observed, independently of the relative contribution of the component processes to the integrated process and of applied variations in the process conditions. Evidently, the mutual interactions between the component processes and products were negligible under experimental conditions.

Preambles and resolutions relating to revision of U. S. copyright and patent laws**This draft was prepared by Dr. F. E. Stewart, chairman of the Committee on Patents and Trade-marks, A. Ph A., for Dr. S. Solis Cohen, Chairman of the Committee on Scope, U. S. P. IX. It was also submitted in the report of the Committee on Patents and Trade Marks, of the Merchants’ and Manufacturers’ Association of Philadelphia, composed of Ernest T. Trigg (President Philadelphia Chamber of Commerce), Charles A. Wagner and Dr. F. E. Stewart, and approved. The matter in italics is suggested for revising the present U. S. Copyright and Patent Laws, and the subject is submitted for study by the members of the American Pharmaceutical Association, preparatory to its discussion at the next annual convention. The Committee received instructions at the last meeting to proceed with the revision, and the Chairman is desirous that the subject be carefully considered from every viewpoint.The Committee believes that all ambiguity now existing in the law should be removed in the revision. Provision should also be made in the law so that the inventor of a new process can secure a royalty from the original patentee. Attention is again directed that matter in italics embody the suggestions of the Committee for additions to the copyright, patent and trademark laws.—Editor.
