Abstract: An analog-to-digital voice storage cellular telephone for recording voice messages while the user is away from the cellular telephone unit. In a preferred embodiment, the analog-to-digital voice storage cellular telephone comprises call answering circuitry which is activated after a predetermined number of rings. Detection circuitry waits to detect a SAT signal during a preset period of time. Once the SAT signal is detected a prerecorded outgoing message is transmitted to the caller. The voice storage cellular telephone records incoming voice messages which are retrieved and replayed by users at their convenience. If the SAT signal is not detected, call terminating circuitry immediately terminates call. In accordance with one aspect, voice messages may be recorded at the central cellular station in real time, subsequently transmitted to the voice storage cellular telephone at a high speed and reproduced at normal speed to reduce air transmission time and cost.

Abstract: In a textile machine, the drive (1) consists essentially of a motor (12), a first pair (121, 122) of belt pulleys and a second pair (131, 132) of belt pulleys and a belt (133) stretched between them. In displacing the connecting rod (37) and pivoting the adjusting lever (124), a first adjusting device (38) brings about a change in the speed at the drive shaft (130), while the speed of the motor shaft (120) remains the same. In the case of a sudden machine stop, a second adjusting device (39) comes into action, the lifting cylinder (30) being bled via the bleeder (32) and the piston (31) with the adjusting lever (124) thus moving to the right, as a result of which the belt pulley (122) moves away to the right from the belt pulley (121) and the belt (133) thus moves to the minimum diameter on the belt pulleys (121, 122) during the deceleration of the motor (12). The set position of the belt (133) for switching on the motor (12) again is thus already guaranteed when the machine is switched off. <IMAGE>

The symbol of the fabric of the belt band is <IMAGE>   The counter is 3. As seen in weft section, during the weaving operation those weft yarns (30, 31) individually crossed by a warp yarn (27) at the top or bottom pass into the adjacent group of five weft yarns (29, 32, Figure 2). In the finished fabric, each warp yarn (40) alternately loops round six weft yarns (1 to 5, 7 or 6, 8 to 12, Figure 3) from the upper and from the lower side of the fabric. In the finished fabric, the groups of these six weft yarns are divided in three layers into one (3, 10), two (2, 5; 8, 11) and three weft yarns. The high flexibility and sewability arise from, among other things, the fact that, as seen in weft section, only one warp yarn (40 or 41) runs respectively between any mutually adjacent weft yarns (for example, 5, 6 or 2, 4) of adjacent layers. <IMAGE>
