Title: Improvements in or relating to machines for making envelopes or the like
IPC: B31B19/00
Filed: 1920-04-17
Abstract: 151,561. Smithe, F. L., and Novick, A. April 17, 1920. EnveLopes, making.-In a machine for making window envelopes, the station at which the envelopes are folded is situated in a line with, but between, the picker station at which the blank is gummed, and the patch-applying station, so that a blank after being gummed is moved forwards to receive the transparent patch and is then moved backwards to be folded. A blank is lifted from a pile 3 by means of gummed pickers 7, 8, 9 and is conveyed by slides 12 to station 3<c> at which the patch is applied. At this position, the blank is supported by a hollow table 16 which has its upper surface perforated and is connected by a tube 18 with any known device for exhausting air at predetermined periods. The patches are stored in a carrier 19 carried by an arm that oscillates about a shaft 25. After the carrier has descended to deliver a patch a presser 28 descends and presses the patches against the blank, so that the lowermost patch is retained by the gum on the blank. At the same time, the air is exhausted from the table 16 so that the patch is retained while the carrier 19 rises. The blank is now moved backwards by slides 14 into position above an opening 20 in the table through which it is pressed by a plunger 32 into a folding-box of usual construction.

Abstract: 294,287. Vautin, C. T. J., and Stephens, C. V. April 22, 1927. Methylstannic tri-iodide is prepared in a watersoluble form for therapeutic purposes by first forming methylstannoxylic acid by the interaction of methyl iodide and an alkaline stannous solution in the presence of alcohol with maintenance of the temperature between 30‹ and 40‹ C., and then heating it with hydriodic acid in known manner. The temperature is preferably maintained by water cooling. The resulting stannic tri-iodid,e may be ground into a cream with a small quantity of liquid such as water, which is a solvent for hydriodic acid, the solid separated and crystallized from a non-aqueous solvent such as petroleum; the product may be recrystallized from a fatty acid such as acetic or propionic acid. If desired the methylstannoxylic acid may be isolated, prior to its treatment with hydriodic acid, by adding an excess of a.mineral acid and fixing the excess with ammonia. An example is given of the preparation of methylstannoxylic acid from stannous chloride and methyl iodide, its treatment after isolation with hydriodic acid, and the subsequent purification of the methylstannic tri-iodide produced.

Title: Improvements in means for rectifying alternating currents
IPC: H01L21/00
Filed: 1926-05-01
Abstract: .264,052. Gill, E. R. May 1, 1926. Converting electric currents.-A crystal rectifier suitable for charging storage batteries from alternating current mains comprises a crystalline fragment one side 10 of which has been modified by abrasion, the fragment being resiliently held with its modified face against a conducting member by means of a pointed contact member 19 carried on a spring strip 17. Abrasion of the face 10 may be effected by grinding on an emery wheel and serves to reduce the contact resistance as well as to avoid nullifying the rectifying effect on one side by an equal effect on the other by destroying the sensitivity of the crystal on the abraded face. The rectifying effect may be further improved and stabilized by subjecting the crystal before use to a forming operation consisting in passing through the point of contact with the member 19 a higher current than that normally to be dealt with for about twenty four hours. A layer of tin or lead foil 15 may be interposed between the crystal which may be pyrites and the conductor 13, and the pressure of the contact member 19 which may be silver may be adjusted by a screw 20. A number of rectifying couples may be arranged in series or parallel according to the voltage and amount of current to be dealt with. Fig. 7 shows an arrangement for charging a battery 26 and comprises a transformer 23, 24, and a number of parallel connected rectifier units each consisting of two couples in series connected to busbars 25, 27 through fuses 28. The number of units in circuit may be varied by movement of an insulating strip 30 adapted to enter between the busbar 25 and the contacting portions 29 of the rectifier elements.
