Inventor: PERRY FRANK
IPC: C01B17/775
Filed: 1911-09-09
Granted: 1912-05-02
Abstract: 20,063. Perry, F. Sept. 9. Sulphuric acid.-In the manufacture of sulphuric acid by the action of sulphuretted hydrogen on a solution of copper sulphate, the precipitated copper sulphide is reconverted completely into sulphate, after calcination, by treating with sufficient sulphuric acid to convert the portion of copper oxide into sulphate. The acid used may be that obtained in the first stage of the process. The invention is particularly applicable to the removal of sulphuretted hydrogen from Mond or like gases, the acid produced being used for the extraction of the ammonia in them.

Abstract: 27,136. Standard Wrapping Machines, Ltd., Holden, A. P., and Morgan, P. Nov. 2. Packeting by wrapping-up. - Relates to a machine for wrapping-up loaves of bread and like articles. The present Specification describes the apparatus for placing the wrapper round the article and for forming the longitudinal fold. The apparatus for forming the end folds is described in Specification 7778/14, but forms part of the present machine. The wrapper 1, Fig. 15, is drawn from a web by intermittently rotating feed-rollers 14, 15 and fed between shears 16 over the article A, which has been placed on an elevator table 5 by any suitable conveyer. The shears 16 cut off the wrapper 1, and the elevator 5 rises to the position shown in Fig. 23. The article is held in this position by a finger 104, Fig. 25, stop 103, and sliding plate 100 after the descent of the elevator and while the depending sides of the wrapper are forced by a sliding plate 66 between two spring - pressed jaws 84, 85, thus partly forming the longitudinal fold. The jaws 84, 85 close upon the fold, when the plate 66 is withdrawn, and are rotated upon their supporting- pivot 90 so as to complete the fold, as shown in Fig. 26. The partly wrapped article is then pushed to the right to the end-folding mechanism. To stop the machine automatically when the supply of articles brought by the conveyer 46, Fig. 35, ceases, a lever 254<a> is arranged to rest on the tops of the articles as they pass beneath. If the supply ceases, the lever 254<a> falls and operates an electric switch 248 by means of a bent lever 252, thereby stopping the machine.
