Title: Ultra-sonic wave generator - controls oscillator output frequency to maintain maximum amplitude of detector output signal
Inventor: WATANABE AKINORI
IPC: B06B1/02
Filed: 1974-10-12
Abstract: The ultra-sonic wave generator circuit consists of a rectifier (4) connected to a slope detection circuit (5) which produces an output signal when its internal "sample hold" input voltage is reduced. This output signal is fed to the differentiating circuit (6) which transmits a signal to the OR circuit (7) and to the binary counter (8). The output from the binary counter (8) goes to the integrator (9), the output of which passes to the voltage limiter (10) and onto the voltage controlled oscillator (11) and then through the amplifier (12) to the driving electrode (13a) of the ultra-sonic generator (13). The output from the detector electrode (13b) is fed back to the rectifier (4).

Title: Various spech sounds identifier - using bank of capacitors of differing values connected in parallel
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: G10L15/00
Filed: 1975-06-16
Abstract: A speech sound, converted into an electrical signal by a microphone, is applied to a bank of capacitors connected in parallel. The capacitors are all of different values and each has an indicating instrument connected in series with it. As the capacitors are all of different admittance, the indicating instruments will all respond differently. The proposed method relies on this pattern of responses being different for different speech sounds. Characteristic responses to known speech sounds can then be recognized and used afterwards to identify unknown sounds. The procedure allows not only for the several indicating instruments to respond differently overall, but also for their maximal response to occur at different times. This time sequence is also to be taken into account in identifying unknown sounds.

Title: Improved mantle for sintered arc furnace electrodes - reduces the number of fractured electrodes by means of a suitably shaped inner mantle geometry
Inventor: ANDO RYO
IPC: H05B7/09
Filed: 1975-09-05
Abstract: Self sintered electrodes are used in electric arc furnaces, as used in the manufacture of certain electrodes and carbides. The electrode consists basically of a cylindrical metal tube (1) or mantle, inside which are welded longitudinal k section struts (8), through which, rows of holes may be drilled. An electrode paste (2) fills this mantle, and when in use the heat of the arc sinters the section of this nearest the arc (5) and produces a solid electrode. As this wears down, more paste falls down and becomes sintered, and the electrode remains the required length. Struts of sawtooth shape may be used instead of drilled holes in order to reduce breakages.

Title: Duplicated fire alarm network - reduces false alarms by double threshold which defines status
Inventor: ESSER KLAUS
IPC: G08B17/00
Filed: 1975-10-03
Abstract: The method is for reducing false alarms produced by fire alarm systems which can be actuated by smoke and heat not caused by a major fire. It depends on duplicating the detection network and providing two distinct signal thresholds each defining an alarm status. In its simplest form, two distinct systems (L1, L2) each serving a chain of transducers (111, 112, 11n, 121, 122, 12n) operate in parallel. One chain is more sensitive and sets off a local alarm (NFM) while the other sets off a general alarm (HFM) when a higher signal threshold is exceeded. This arrangement may be developed slightly by incorporating a logic AND or OR gate in the main alarm trigger, which then monitors both networks. A time delay circuit in the higher sensitivity network can be incorporated before the logic gate, so that short-lived transducer outputs are ineffective.
