1 and assuming the speed of rotation of cylinder A to be the same, the apparatus will now be evidently adapted for a number of impulses per unit of time twice a great as in the preceding case. In all cases it is evidently important to adjust the duration of contact of segments. 8 and s' with brushes b bh, in the manner indicated. When the apparatus I have described is used in connection with the transmission of signals or intelligence, it will, of course, be understood that the transmitter is operated in such a way as to produce disturbances or effects which are varied or intermitted in some arbitrary manner, for example, to produce longer and shorter successions of impulses corresponding to the dashes and dots of the Morse alphabet, and the receiving device will respond to, and indicate these variations or intermittences, since the storage device will be charged and discharged a number of times corresponding to the duration of the successions of impulses received. obviously the special appliances used in carrying out my invention may be vari ed in many ways without departing from the spirit of the same. Art is to be observed that it is the function of the cylinder A, with its brushes and connections, to render the electrical impulses coming from the plates P and P¹ suitable for charging the condenser (assuning them to be unsuitable for this purpose in the form in which they are received) by rectifying them when they are originally alternating in direction, or by selecting such parts of them as are suitable when all are not, and any other device performing this function will obviously answer the -14393
