Abstract: 1,095,405. Stethoscopes. J. A. BERSAC, F. H. J. LE BOITEUX and C. ROZET. Feb. 5, 1965 [Feb. 11, 1964], No. 5139/65. Heading A5R. [Also in Division H4] Stethoscopic apparatus comprises a stethoscope contact head 21 (Fig. 2) to be applied to the body of a patient, a first resonant chamber 34 connected to the contact head 21 to receive sound therethrough, a microphone 30 responsive to sound received by the chamber 34, an electronic amplifier to the input of which the microphone 30 is connected, an electro-acoustic transducer 31 to which the output from the amplifier is connected, a second resonant chamber 37 arranged to receive sound from the transducer 31 and a stethoscope listening device 27, 28 connected to the chamber 37. The chambers 34 and 37 simulate the acoustic characteristics of conventional stethoscopes. The diaphragm 33 of the microphone 30 forms one wall of the chamber 34 and, similarly, the diaphragm 36 of the transducer 31 forms one wall of the chamber 37. A tube 40, with a valve 41, and preferably with valves 41 1  and 42 2 , permits by-passing of the electronic amplifier and enables the practitioner to compare the sounds heard with and without amplification. Components may be detachable. Substitution of an appropriate contact head 21 may be facilitated by providing the tube 25 with a coupling, Fig. 10 (not shown) comprising a vented spigot (42) for connection to the chamber 34. The vent prevents undue pressure being applied to the diaphragm 33 and is closed by the tube 25 only shortly before the connection is completed. The stethoscopic apparatus may be contained in three cylinders 50, 51 (Fig. 6) and 52 (Fig. 4) held together by a rod (59) Fig. 3 (not shown). Cylinder 52 houses the microphone 30, the transducer 31 and the resonant chambers 34, 37. The container 50 houses a battery 60, while the container 51 accommodates an electronic amplifier.

Abstract: 1,226,188. Transistor clamping circuits; automatic frequency control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 15 Oct., 1968 [18 Oct., 1967], No. 48883/68. Headings H3A and H3T. A clamping circuit comprises a contro transitor 33 having its output electrodes connected through resistors 36 and 37 to the terminals of a D.C. supply and two diodes 34, 35 connected in series in the same polarity across the output electrodes, the common connection of the diodes being connected to the point to be clamped. When the transistor is not conducting the diodes are current biased to conduct and as the two resistors 36 and 37 in the embodiment are equal the connection between the diodes is clamped to a value of half the 2 volts supplied at the upper end of resistor 37 (i.e. to 1 volt). When the transistor conducts the current bias is diverted and the diodes are non-conducting unless the voltage at their common connection varies by more than their threshold voltage (e.g. ¢ volt) from the 1 volt level. Negative feedback through 51 reduces the steepness of the control by the transistor. The circuit is used to remove the A.F.C. voltage in a radio receiver when the tuning is outside a desired range. The A.F.C. voltage derived from a discriminator 22, 23 is applied to a varactor diode 46 through resistors 43 and 44, the other terminal 46 being connected to a reverse bias source comprising a Zener diode 47 and a 1 volt supply from 32. The transistor 33 is controlled by a voltage doubler rectifier 38, 39 from the output of the I.F. stage so that if the output from the stage falls below a give value the A.F.C. line is clamped to 1 volt and the A.F.C. is ineffective. This limits the capture and the hold range of the circuit to a narrow band where the interference from adjacent channels is small.
