Filed: 1926-11-03
Abstract: 282,939. Mond, A. L., (Metallbank und Metallurgische Ges. Akt.-Ges.). Nov. 3, 1926. Scrubbers and washers; tar.-Gas cooling and washing apparatus comprises a number of convergent-divergent passages acutely bent at their narrowest portion and adapted sharply to divert the direction of flow of the gas, the passages being arranged on the surface of a body mounted on a rotating shaft. If the gas contains liquid particles, e.g. tar fog, a separate wetting of the passage walls by washing liquid may be unnecessary. Fig. 1 shows two passages 1 arranged in series formed by rings 2, 3, in a casing 4, washing liquid being admitted from above, and the gases being introduced either from. above or below. One or more of the rings, e.g. the inner rings 3 rotate around a shaft 5. In a modification, nozzles are arranged upon the surface of a cylinder mounted on a rotatable horizontal shaft with a part of the nozzles always immersed in liquid, the level of which is adjustable. Liquid may also be introduced through a conduit to moisten the nozzles uniformly. Gases pass from above through the nozzles and are withdrawn axially of the cylinder. The individual passages or groups of passages may be so arranged as to be removed during working and reinserted after cleaning or replaced by other passages. A further modification comprises a two-stage separation of tar from steam-containing gases, a first washer working above the dew point temperature with an injection of tar, and the gases then passing through an irrigation cooler supplied with water from a second washer in which the gases are finally purified.

Title: Method and means for measuring the microphonic action of multi-electrode tubes
IPC: G01R31/24
Filed: 1947-10-14
Abstract: 658,253. Testing thermionic valves. GUYOT, G. J. L., and GILLETT, P. Oct. 14, 1947, No. 27573. Convention date, Oct. 16, 1946. [Class 37] The microphonic. properties of a valve are investigated by subjecting it to sound vibrations of a variable frequency and measuring the resulting variations in anode, screen or grid current. As shown in Fig. 1, a loudspeaker 2 emits a variable frequency note to act on the valve 3 whose anode current is recorded at 7 ; the variations in anode current due to variation of sound level as frequency varies are determined by using a linear-response microphone 4 in place of the valve 3. In a modification, the loud-speaker acts on a microphone whose rectified output is applied to vary the bias on the amplifier fed by the valve 3 so as to correct for variations of sound level, Fig. 3 (not shown). Alternatively, the oscillator feeding the loud-speaker may be controlled to constant amplitude by the output of the linear response amplifier, Fig. 4 (not shown). According to the Specification as open to inspection, a microphone 4, Fig. 2 (Cancelled), is in parallel with the valve 3 under test, and the combined output is differentially combined with the output of another microphone 9. This subject-matter does not appear in the Specification as accepted.

A Schmitt trigger circuit has an R.C. circuit across the transistor which is normally conductive so that application of a control voltage above a certain threshold value produces continuous oscillations. In Fig. 1 the feedback circuit R2, R3, C across transistor Tsl will ensure oscillation if the control voltage Ust is great enough for C to charge up sufficiently to produce conduction in Ts1 after it has been cutoff by multivibrator action. For values of Ust below this critical point the circuit will be quiescent, but will act as a monostable multivibrator if supplied with pulses which are short compared with the discharge time of C. If Ust is too large, oscillations can be inhibited again, and therefore the input is limited by a Zener diode Dz. The circuit is useful as a voltage discriminator in control systems, and can be transformer-coupled to a transistor current switching circuit and bridge rectifier to give a D.C. output (Fig. 2, not shown).
