Filed: 1920-07-10
Abstract: 148,830. Aegir Electrische Bordapparate und Motoren-Ges. Schwarz & Co. Dec. 4, 1918, [Convention date]. Alarms, high and low water.-A wheatstone bridge arranement indicates at a distance when the level of a liquid is above an upper or below a lower limit. The fourth arm c, f of the bridge illustrated comprises a high resistance V and the resistance of the liquid. It is shortcircuited when the liquid rises above the electrode Pa, and interrupted when the liquid falls below the electrode Pi. When the level is between these two limits a null .effect is obtained in the signalling apparatus. The resistance V is large enough to mask any changes in the resistance of the liquid or of the earth connexions.

Title: Improvements in or relating to wireless receiving systems
IPC: H04B1/20
Filed: 1935-07-22
Abstract: 460,214. Wireless receiving circuits. COSSOR, Ltd., A. C., and STRAFFORD, F. R. W. July 22, 1935, No. 20828. [Class 40 (v)] A wireless receiver having a potentiometer R constituting the load resistance of a diode demodulator D1 has a switch S which connects a gramophone pick-up P.U. in series with a D.C. source to feed into the diode circuit, the pick-up voltage being built up across R while the diode is biassed by the said source to prevent rectification of the pick-up voltage. Highfrequency signal currents in LC are rectified across R in the usual way with S open ; with S closed they are byepassed from the diode by the pick-up. The source of D.C. voltage shown in series with the pick-up is the delay voltage of the A.V.C. diode system D2-R2 and appears across R1. If a piezo-electric pick-up is employed it should be shunted by a high resistance. The delay voltage must be at least equal to the maximum output voltage of the pick-up.

Abstract: 1,022,199. Automatic tension control. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT m.b.H. May 21,1964 [May 24, 1963], No. 21047/64. Heading G3R. [Also in Division H2] A reel 4 for magnetic tape is driven by singlephase motor 5 whose speed is controlled by lever 9 associated with a loop of tape. A control voltage proportional to tape-tension is supplied from generator 11 to monostable multivibrator 12 pro-. ducing a train of rectangular pulses whose width is modulated in accordance with variations in the tension. The train of pulses is applied to a switching amplifier 14 which in interrupts the motor voltage at such a high frequency as to prevent fluctuations in the motor torque. In addition, the generator 11 controls a pulse generator 13 for varying the frequency of interruption of motor voltage as well as the duration thereof. The multivibrator 12 comprises transistor T1 which is blocked by a negative pulse applied at terminal k1 from the generator 13, whereby transistor T2 is rendered conductive and a negative potential is applied to one plate of capacitor Ct. The dwell time in the semistable state of the multivibrator 12 depends upon the discharge period of capacitor Ct and this is varied by the control voltage at terminal k2 which is derived from generator 11 and applied to transistor T3. The pulses at the collector T1 are supplied through terminal k3 to the amplifier 14. The motor is associated with a bridge rectifier having one terminal connected to earth directly, and another terminal connected to earth through a transistor whose base is supplied with pulses from the amplifier 14, Fig. 3 (not shown).

Abstract: 810,912. Loud-speakers and circuits therefor. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 8, 1957 [July 11, 1956], No. 21553/57. Class 40 (4). In an arrangement for the acoustic reproduction of gramophone or tape recordings a wide-band amplifier 3 operating far into the ultrasonic frequency band (up to over 60 Kc/ sec.) feeds the moving coil 4 of a loud-speaker having a rim-mounted diaphragm 5 of comparatively low rigidity for reproducing the low and medium tones (up to about 10 Kc/sec.) and a free-edge diaphragm 6 of a much greater rigidity and having a rigid bent-over edge 8 for reproducing the high tones and ultrasonic frequencies (from about 10 Kc/sec. up to about 40 Kc/sec.). By suitable choice of the mass and rigidity of the diaphragm 6 it can be made to limit acoustic energy substantially only adjacent the edge 8, the average value of this energy approximating to that of the energy emitted by the diaphragm 5. This energy emission by the diaphragm 6 extends over considerably more than an octave, the very narrow edge 8 (approximately 1 mm.) allowing the diaphragm 6 to have a very high cut-off frequency of up to 40 Kc/sec. By use of this arrangement the " coloured noise " which occurs in a frequency band close below the cut-off frequency of the reproducing equipment is shifted into the ultrasonic range and is not therefore audible, the resulting " white noise " being less perceptible than the normal " coloured noise ".
