Abstract: 1,264,565. Substation apparatus. PIONEER ELECTRONIC CORP. 15 May, 1970 [19 May, 1969; 27 June, 1969], No. 23750/70. Heading H4K. A telephone answering machine including a timing device is set into operation upon receipt of an incoming call and having a component which is reset after completion of a preliminary announcement. In the embodiments described a capacitor forming the component commences to charge or discharge upon receipt of an incoming call and is fully discharged or recharged after transmission of the announcement. Both embodiments use two tapes, one for recording the incoming message and the other (preferably a closed loop) for transmitting the announcement. Both arrangements allow the time allowed for an incoming message to be independent of the length of the announcement yet ensure that the line loop is broken after a predetermined maximum time even if the end of announcement signal is missed. In the embodiment shown a starter circuit 12 responds after 3 to 12 seconds of incoming ringing on a line 11, and applies an earth start signal to the base of a normally conducting transistor Tr1, switching it off and switching to conduction a transistor Tr2 energizing a relay Y1 One contact y11 of the relay connects the line to a transformer 13 and another contact energizes a motor to drive a closed loop message tape T, causing a prerecorded announcement to be transmitted to line via pick-up 14 and amplifier 15. A changeover contact y12 of the relay connects a fully discharged capacitor C2 to the base of the transistor Tr1 to maintain that transistor in the blocked condition, after operation of the contact y11 and termination of the start signal, until the charge on the capacitor reaches a predetermined level. If the capacitor is allowed to charge to this level the relay Y1 releases and the substation returns to an "on hook" condition. Normally, however, a conductive member 16 carried by the tape T1 is detected by contacts 17. An oscillator 18 responds, causing a tone pip to be transmitted to the caller to indicate the start of the recording period and after a short delay a switching circuit 19 operates a relay Y2 which initiates the drive of a tape T2 used to record an incoming message and operates a contact y22 to connect a record amplifier 20 to the line. The tone pip in addition to being transmitted is picked up and smoothed by a circuit D2, D3, C3, R5 and applied to the base of a transistor Tr3. Tr3 turns on discharging a capacitor C4. At the end of the tone pips Tr3 turns off and C4 recharges via resistors R6 and R7 and during charging switches a transistor Tr4 to conduction, causing C2 to be discharged. Thus the timing circuit which determines the operative period of the relay Y1 is reset at the end of the announcement tape.

The ribbon 30, composed of several or, as shown, two plies 44, 46, each of which may be of laminated construction, may be formed of vinyl chloride or vinylidene chloride or of "Cellophane" (Registered Trade Mark) coated on one side with polyethylene. More complex compounds are referred to as suitable for forming the ribbon 30. The pouch 12, formed for example of a laminate construction of a paper exterior and an inner surface 28 of thermoplastics such as polypropylene, or polyethylene terephthalates coated on the inside with low-density polyethylene, can be extruded, or formed from separate sheets sealed together. Alternatively, the bag can be formed from a single web wrapped around a hollow mandrel and sealed along its overlapping edges, as at 26, and filled by the usual forming, filling, and sealing process. Intermediate plies, or a core, of barrier material may be incorporated in the walls of the pouch to minimize the egress of gas, or vapour. Other more complex compounds are listed as suitable for forming the walls of the pouch 12. One seal 18, or 20 may extend substantially at rightangles to the other to provide a tetrahedral. shaped pouch.
