Abstract

729,387. Substation equipment. MULLER, W. June 24, 1953 [June 25, 1952], No. 17576/53. Drawings to Specification. Class 40(4). [Also in Group XXXVIII] A substation is provided with magnetic sound recording and reproducing apparatus (see Group XXXVIII) and with means which on the receipt of a telephone call cause the apparatus to play over to the calling subscriber a reply message, which the user of the apparatus has previously recorded at will, followed by an invitation to speak, after which for a predetermined time the apparatus records a telephone message dictated to it and then, on the expiry of the predetermined time, gives to the calling subscriber a spoken message to the effect that the apparatus is being switched off, and finally restores all its working parts to their respective conditions of readiness to receive a new call. The apparatus may also be used, under the control of a manually-operated switch, for recording dictation or a telephone conversation, an audible warning signal being given in the latter case. Reply messages are recorded on a disc, and incoming telephone messages, conversations, or dictation are recorded on a cylinder, each being driven by an individual electric motor. The motor driving the reply disc also drives a cam which performs the requisite switching operations.
