Patent CH-618557-A5 (CH)
Title: Telephone installation including for each telephone set a device for transmitting and receiving coded telephone pulses
Inventor: PRUDHON LUCIEN PIERRE EMILE
IPC: H04J3/02
Filed: 1976-11-05
Abstract: The device includes a modulation path, a demodulation path, and electronic switchgear. The demodulation path includes an active filter of the SALLEN KEY type with TSCHEBYSCHEV behaviour, preferably of order six with a low-pass response curve, producing compensation for the distortion as (sin  omega  tau 2)/  omega  tau 2 which is due to the demodulation,  omega  being the angular frequency of the low-frequency signal and the width of each sampling signal. This arrangement makes it possible to eliminate the demodulation distortion very effectively. The active filter (FAD) represented includes an input stage with operational amplifier (2) and three structures of the SALLEN KEY type of second order each including an operational amplifier with low consumption. The modulation path and the demodulation path are connected to a set by way of a line and of switchgear for the transmitted and received signals culminating respectively at a modulator and at a demodulator. The semi-conductor electronic switchgear possesses three pairs of poles, one of which is joined to the telephone set and the other two of which are joined to the modulation and demodulation paths respectively. <IMAGE>

Filed: 1976-11-09
Abstract: In a piston engine designed as a compressor circularly curved pistons (2,3) and cylinders (2a, 3a) rotate on a circular orbit and during the rotation as a result of their stroke perform swivelling movements relative to one another. The pistons (2, 3) and cylinders (2a, 3a) are connected to one another by way of supporting parts (5, 5a) and by way of a transmission mechanism comprising two transmission parts (8, 8a). They are driven by a shaft (16) which can be brought into engagement with either of the supporting parts. Control cams (14, 14a) serve for controlling the positively closed cycle of movements of the machine. Each transmission part has a single set of teeth (10, 10a), which engages with internal teeth (15a, 15) of the opposing supporting part (5a, 5). The free-wheels necessary according to the main patent for a general piston engine are dispensed with. <IMAGE>
