Abstract: 1,270,840. Automatic voltage control. ROBERT BOSCH G.m.b.H. May 1, 1969 [May 2, 1968], No. 22257/69. Heading G3R. The rectified output voltage of a variablespeed three-phase permanent-magnet alternator 28 is maintained at a predetermined value by connecting respective rectifiers 35, 36, 37 of the bridge 30 in parallel with respective thyristors 78, 79, 80 whose control electrodes are supplied from the output windings, 72, 72', 72" of a blocking oscillator formed by a transistor 68 and primary transformer windings 70, 71, the arrangement being such that when the output voltage is below the predetermined value the oscillator produces no output and the thyristors are non-conductive, and when the output voltage exceeds the predetermined value a Zener diode 73 conducts to cause the oscillator to produce firing pulses which make the thyristors conductive to short circuit the alternator output windings. The frequency of the oscillator output pulses is dependent on the output voltage and increases with increase of this voltage to increase the conductive periods of the thyristors. In a modification, Fig. 1 (not shown) the oscillator has only one output winding which supplies the thyristor control electrodes through respective resistors serving to distribute the firing current equally thereto. This modification is applied to an alternator having its windings connected through respective rectifiers to the lead 34 and its star point connected to the lead 38, Fig. 3 (not shown) and to an alternator having a single output winding and a bridge with four rectifiers, two of which are in parallel with respective thyristors, Fig. 4 (not shown).

Title: Sound level meter
IPC: G01H3/14
Filed: 1976-05-28
Abstract: 1506552 Sound level meter DEERE & CO 28 May 1976 [30 May 1975] 22329/76 Heading G1G A sound level meter for use with a transducer (e.g. a microphone or dial-type analogue meter) comprises a circuit 78 for averaging the input: signal, a logarithmic circuit for converting the average signal so produced to a logarithmic signal that controls an automatic range selection circuit 68 to increase or decrease the gain preceding the logarithmic circuit as the logarithmic signal respectively falls below and rises above threshold values and to vary an offset on which the logarithmic signal is superimposed to compensate for the gain change. As described the averaging period of an R.M.S. signal is selectively variable from a maximum of 10 seconds for continuous sound to a minimum of 0À035 seconds. When the output from the log. converter 56 falls below a threshold value the ranging circuit 68 automatically boosts the input level to a driver 50 by 30 db and simultaneously subtracts 30 db gain from the summing amplifier 60. These 30 db gains are removed when the signals exceed a maximum desired value. The reset switch 76 momentarily activates the minimum time averaging without altering any longer averaging period which may be in use. The hold circuit 61 enables the highest output from the amplifier 60 to be stored until reset. Resetting may be by switch 76 or by any change initiated in the automatic ranging circuit 68 via lines 69 and 75. The summing amplifier 60 gives a read-out in db's on the digital voltmeter 62. The preamplifier 20 has a scaling adjustment to give the proper sound level reading during calibration.

Title: Coated metal electrode for electric arc welding
IPC: B23K35/04
Filed: 1962-06-13
Abstract: A coated metal electrode for electric arc-welding wherein the coating contains organic substances at least partly, if not exclusively, in the form of leaf particles.  Leaves of clover, eucalyptus, laurel and mint may be used and in general the leaves of aromatic plants excepting those containing mainly phenols are suitable.  It is preferable only to use that part of a leaf intermediate the ribs, said ribs being removed by maceration; alternatively, if the whole of the leaf is used it should have few ribs., e.g. clover-leaf.  The leaves are used in the form of particles for uniform distribution in the coating mass and should pass through a 50 mesh screen; the dried leaves may be ground or chopped.  Examples refer to coatings containing 30% of leaf material.  Mint leaves replacing ordinary cellulose in the electrode coatings are said to considerably increase the stability of the arc when the coating is humidified by exposure to the air.
