Title: Telephone substation automatic operating system
IPC: H04M1/2749
Filed: 1972-12-12
Abstract: 1379805 Telephone substation equipment YEDA RESEARCH & DEVELOPMENT CO Inc 12 Dec 1972 [16 Dec 1971] 57365/72 Heading H4K A repertory dialling system incorporates logic responsive to signal tones on an associated subscriber's line for controlling the operation of the apparatus. A call sequence is initiated by a manual start key. If no dial tone is provided within a preset period or if the tone present on the line does not conform to a laid-down characteristic, an alarm buzzer is sounded and possibly an alarm lamp is lit. If tone is provided, a first selected entry in a 4-word memory, each word being of up to 16 digits, is read-out to a register. A lamp associated with the key which selected the entry is caused to flash. The local handset is disconnected. The register is readout digit by digit whereby corresponding impulse trains or VF codes are transmitted by means not particularly specified. If busy tone, or a tone not recognizable as ringing tone, occurs, or if ringing tone persists unduly the connection is released for a preset period (during which incoming calls are permitted). The next number in the selected set of numbers is read from memory into the register and the dialling cycle repeats. The sequence of selected numbers may be run through a predetermined number of times before the apparatus cuts-off. If the called party replies as detected by cessation of tone or polarity reversal, or, if there is no tone on the line, the buzzer and lamp are actuated so as to alert the operator. In order to prevent a called party from hanging-up if the operator does not respond immediately, a prerecorded tape loop is started upon the reception of ringing tone. The output of the tape is gated to line between ringing bursts and continues upon cessation of ringing due to answer. If the operator does not reply within a predetermined time, the apparatus cuts-off. When the operator hangs-up after speaking to the called party, the logic causes the next selected number to be rung. A sequence switch scans the words in memory looking for those marked by operation of an associated key and permitting the marked ones to be dialled as described above. If a call is answered its marking in the memory is removed. If a party is rung but does not answer his marking is usually removed. Tone identification is effected with the aid of integrating circuits and possibly frequency discriminators. Timing is effected by analogue or digital circuits. The apparatus may be associated with more than one exchange line.

The pairs of snapping rolls 40, 42 are driven in opposite rotation by gear assembly 60, 62, 64, 63, the bevel gear 63 being slidable but non-rotably mounted on drive shaft 78. Similarly, the gathering chains 34 with fingers 32 are driven by sprockets 36, 38, 36 being directly rotated by bevel gear assembly 68, 69, the bevel gear 69 being slidable but non-rotably mounted on drive shaft 80. A gear housing portion with bearings (not shown) encases each gear assembly so that the gears within it remain in fixed relation to one another when clamps 88 are released and the gathering and snapping units moved along the support bar 76. A power shaft 118, driven from a shaft 183 that drives conveyer 20, is provided with a sprocket 180 that communicates a drive to the auger conveyer 14 via chain 179 and sprocket 181, a variable speed pulley 150, and a pulley 122. The gathering chain drive shaft 80 is driven from pulley 150 via a second variable speed pulley 168 and sprockets 140, 142. The snapping rolls are driven from pulley 122 via pulley 126. Both belt drives 166 and 124 are designed to slip if either the gathering chain or snapping rolls jam. The operator, by means of a lever and cable (not shown) may vary the speed of the gathering chains whilst the combine is in operation. Adjacent pairs of gathering and snapping units are moved toward or away from each other by rotation of a turnbuckle (not shown); other means, e.g. hydraulic, may be used for this purpose. The hood assemblies (Fig. 9) have panels 252, 253 with overlapping edges that move relative to each other according to adjustment of the gathering and snapping units. Overlapping plates 266 and 268 are slotted to receive fasteners 270 and 272. Hinge members 228, connected to the hood by bracket 276, secure the side frame members of the gathering and snapping units to the hood. On movement of the units panels 258 and 260 rotate about pivot 264 that is located in the conical portion 262.
