摘要： Two circuit embodiments are disclosed for discriminating between a voice signal and other audio standard (busy and dial tone) signals on a telephone line. One embodiment measures the frequency of the envelope of the audio signal and decides voice (speech) presence if (glottal) frequencies above 50 hz. are present. The second embodiment measures the cyclic frequency of the audio signal and decides voice (speech) presence if frequencies above 600 hz are present, assuming busy or dial tones are 400 hz. Features of the second embodiment include gating of the timer-counter to prevent the cycle-counter from erroneously counting chatter during rise-time and fall-time of an audio signal.

摘要： A player for magnetic tape recordings is provided, which comprises a cartridge holder adapted to receive therein a cartridge, guide grooves for guiding the holder, an ejecting member adapted to depress the holder and an ejecting mechanism for releasing the cartridge. The ejecting member is in the form of a lever. The ejecting mechanism serves to separate the lever from the holder with the advancement of the holder to retain the lever at an upper position separately from the cartridge holder, and to release the lever simultaneously with the starting of ejecting operation. Thus, the cartridge holder is pushed downward and ejected for removal. The player also includes two grooves intersecting each other at an angle of 90.degree. to 180.degree. on a line extending from the lever. These grooves serve to guide therealong both end of the ejecting lever to cause an arcuate movement of the lever.
摘要翻译：提供了一种用于磁带录音的播放器，其包括适于在其中容纳盒的盒保持器，用于引导保持器的引导槽，适于按压保持器的弹出构件和用于释放盒的弹出机构。排出构件是杠杆的形式。排出机构用于随着保持器的前进而将杆与保持器分离，以将杆保持在与仓保持器分开的上部位置处，并且在弹出操作开始的同时释放杆。因此，盒保持器被向下推动并被排出以便移除。播放器还包括在从杠杆延伸的线上以90°至180°的角度彼此相交的两个凹槽。这些槽用于沿喷射杆的两端引导以引起杆的弓形运动。

摘要： A new type of cassette player is provided. The general structure includes a chassis, a receptacle for a cassette, a guide for the receptacle, and reel shafts. The cassette receptacle is movably mounted on the chassis at an oblique position with respect to the main surface of the chassis. The guide translates the receptacle in the oblique position and then turns the receptacle about its trailing edge to place it in a position parallel to the chassis main surface. The reel shafts connected to drive means is adapted to be initially retracted with respect to the path of the receptacle, but be moved into the corresponding reel hubs of the cassette when the receptacle is turned into the parallel position. The space required for cassette loading can be reduced in this new structure.

摘要： An automatic telephone answering device includes a diode bridge rectifier having its input terminals connected across a pair of telephone lines through a first switch, and its output terminals connected across a relay coil through a voltage controlled impedance, such as a Zener diode. A relatively high frequency, high voltage call signal is rectified by the bridge and breaks down the diode to energize the relay coil. This closes a relay switch to actuate a control circuit, whose outputs a) actuate a tape recorder unit to play back a prerecorded message to the caller, and b) simultaneously transfer the first switch to connect the tape recorder unit across the telephone lines through a line transformer. The breakdown voltage of the Zener diode is selected to be above the voltage level produced by sound (conversation) signals and busy tone signals, whereby the device presents a high impedance to such signals and is not actuated thereby.
