Abstract: 1,265,909. Bellows pumps. COMMISSARIAT A. L'ENERGIE ATOMIQUE. Dec.29, 1969 [Dec. 30, 1968], No. 63101/69. Heading F1N. Pumped gas which escapes from the pumping chamber within bellows 4, 6 is prevented from reaching the atmosphere by sealing bellows 28, 29 extending between respective casings 1, 2 and pistons 3, 5 actuating the pumping bellows. The pistons 3, 5 are actuated by a connecting rod 9 having a piston 10 movable in a cylinder 11. Reciprocation of the piston 10 is effected by pressure air admitted alternately to the ends of the cylinder 11 by a distributing valve 13 controlled by pilot valves 21, 22 actuated by cams 25, 26 on the rod 9. If any of the bellows perforate, a change in pressure occurs in the casing 1 or 2, the pressure change being detected by manometers 34, 35. The manometers may be arranged to stop further pumping when they detect a pressure change.

Abstract: 1,266,436. Voice immunity signalling. XE. ROX CORP. 8 Aug., 1969 [12 Aug., 1968], No. 39721/69. Heading H4R.  A detector for voice frequency signals received over a telephone system, e.g. by audio coupling into a handset to operate a facsimile receiver, is rendered voice immune by biasing the detector back so that it will only respond to a signal of above a predetermined level at above a predetermined frequency, reception of such a signal reducing the bias'to allow the detector to respond to the normal signal frequency. As described a signal of 2200 Hz is used as a start signal, the signal being limited at the receiver and constant width negative going pulses derived at each zero crossing. The derived pulses are applied, via lead 10, to the circuit of Fig. 2. Initially transistor 74 is cut off by the bias applied to its base but pulses of a frequency of 4400 Hz, corresponding to an input frequency of 2200 Hz or higher, cause transistor 74 to conduct turning off normally conducting transistor 76. Transistor 76 is connected to a motor drive amplifier to cause the facsimile printer motor to drive, while the drive amplifier output is also arranged to vary the bias on line 15, which was initially zero, to a value such that the drive amplifier is maintained enabled by a pulse input of over 2800 Hz, corresponding to the normal signalling frequency of 1400 Hz for the facsimile system.

The timepiece is further provided with an hour hand 10, so that the hands 1, 10, may indicate the time in the usual way, and with a crown 11 for winding and setting the hands 1, 10. The graduated element 2 is in the form of a rim and may be set by means of its notched periphery 2a or by a setting member 9. Similarly, disc 5 may be set by means of a knurled knob 5a projecting through the glass, or by a member 8. The disc 5 may be provided with a "catch up" mechanism, in which case the member 8 is a push-button, pressure on which causes the disc 5 to advance until zero index 6 is aligned with the minute hand 1, release by the button 8, then locking the disc 5. In use by an aviator, the index 6 of the disc 5 aligned with the minute hand 1, when passing over a signal beacon. The rim 2 is then turned to bring opposite the index 6 the graduation 4 which corresponds to the estimated flight time in minutes for covering the distance to the next beacon. The graduation 7 which is opposite the minute hand 1 then indicates the time elapsed after passing the previous beacon and the corresponding graduation 4 indicates the estimated interval before passing over the next beacon. The zero indexes 6, 3 on the conventional dial indicate the actual estimated times of passing over the last and next beacon respectively, and the position of the minute hand 1, relative to these two indexes, indicates the position of the aircraft relative to the beacons. The timepiece may be in the form of a wristwatch or a clock attached to a panel or to an aircraft control stick.

Abstract: 1305735 Radio signalling; inductive signalling MULTITONE ELECTRIC CO Ltd 25 June 1971 [26 June 1970] 31177/70 Headings H4L and H4U A communication system comprises a transmitter, at least one receiver incorporating A.G.C. and being capable of receiving modulated carrier signals which are transmitted intermittently from the transmitter when the system is in use, and an additional receiver associated with the transmitter and having a sensitivity substantially the same as the upper limit sensitivity of the other receiver or receivers and which on reception of an interfering modulated carrier signal momentarily causes the unmodulated carrier to be transmitted by the transmitter. The arrangement is particularly applicable to pocket paging systems operating over a restricted area either by radio or inductive means. In the absence of a carrier signal the receivers operate at a high sensitivity due to the A.G.C. which increases the possibility of interference from modulated carrier signals of other systems and this is avoided by the present arrangement. A paging system is described in which a conventional pocket receiver responds to frequencies f 1 , f 2  modulated on a carrier. A similar receiver, without the final stages responding to the calling frequencies, operates a relay switch in the transmitter circuit on the reception of a modulated interference signal to cause the transmission of unmodulated carrier.
