Abstract: 1,064,420. Electric analogue calculating. CORNING GLASS WORKS. Dec. 24, 1964 [Dec. 30, 1963], No. 52444/64. Heading G4G. [Also in Division G1] In a system comprising a transducer providing an electrical output signal which changes substantially exponentially as it approaches a steady state value, means are provided for determining the steady state value before the signal change is complete. As shown (Fig. 1), the signal from a glass electrode 22 is given by E = A (1 - e<SP>-kt</SP>), k being dependent on the nature of the transducer. An operational amplifier 28, having a gain of 1/k, provides a first differential E = Ae<SP>-kt</SP> which is added to the main signal E to give the steady state value A. If k is not constant, a second derivative E is similarly obtained by operational amplifier 38, and a correction signal E<SP>2</SP>/E is derived at 46 which is added at 66 to the transducer signal. To guard against transients arising from a not strictly exponential response, absolute value amplifiers may be inserted in one first derivative feed, and in the second derivative feed.

Abstract: 1494753 Fire alarms HOCHIKI CORP 17 Dec 1974 [17 Dec 1973 (3)] 54488/74 Heading G4N In an alarm system comprising a receiving panel 1 having a common alarm 4 and a plurality of repeaters 3 each comprising a sensor 7 and an individual alarm 8 connected effectively in parallel across a pair of source conductors 5, 6, each repeater is provided with a test switch S1 arranged to test the circuit between the respective repeater 3 and the receiving panel 1, in a specified manner, without operating the common alarm 4, the test, if satisfactory, operating the individual alarm 8 until reset by a further switch S2. As described, the sensors 7 may be responsive to temperature rise, flame, smoke or concentration of CO, each repeater 3 being installed in a residence and connected to a receiving panel 1 common to one floor of the building. In the event of a fire, sensor 7 closes thus connecting the coil of relay 11 via arectifier R across the source conductors 5, 6. This action turns off Tr3 and turns on Tr4. Tr1 and Tr2 are turned on because of the voltage developed across R1 so that relay 9 is energized, operating the common alarm 4. Tr5 and Tr6 are also turned on so as to turn on Tr7 after a time delay C1 so that relay 10 is energized later than relay 9. Contacts 10a increase the voltage across source conductors 5, 6 sufficiently to energize relay 11 which operates the local alarm 8. Testing.-Switch S1 is set to its other position so as to reverse the polarity of diode Do1 thus terminating the source conductors 5, 6 by the resistance of relay 11 and resistor Rol. The voltage now present at point X is now such that Tr3 remains conductive and hence Tr4 is off so that relay 9 is not energized and the common alarm 4 not operated. Tro is turned on after a delay Col so that relay 11 can operate the local alarm 8 until reset by switch S2. In Fig. 2 (not shown) additional contacts are provided which are changed by removing the cover of the repeater 3 before operating the test switch S1

The invention of Specification 1, 027,813 is modified in that the aqueous dispersion of pigmented resin, for electro-phoretically depositing a pigmented resin film on a metal object using either D. C. or A. C. is replenished by adding further quantities of resin without further base or water. Preferably the resin is added in a non-aqueous liquid vehicle such as a mixture of a polar and a non-polar solvent. The polar solvent may be an alcohol or alcohol ether, e.g. isopropanol, butanol, butyl carbitol, cyclohexanol, benzyl alcohol, or monoethyl or -butyl ether of (di) ethylene glycol; the non-polar solvent may be an aromatic or a cyclic hydrocarbon, e. g. xylene, naphtha or pine oil. Initially, an aqueous dispersion of pigmented resin may be prepared by adding the equivalent amount of triethanolamine (as base) for a 10% solids emulsion to an emulsion of a homogeneous paint base made by mixing TiO 2  pigment, lampblack, barytes, zinc phosphate, vinyl toluenated alkyd resin and mixed solvent; subsequently, sufficient paint base as above without any triethanolamine may be added after electro-phoretic deposition to obtain a 10% solids emulsion. The alkyd resin may be prepared by reacting dehydrated castor oil fatty acids, trimellitic anhydride, propylene glycol, copolymerizing with vinyl toluene and methyl propanoic acid in presence of di-tertiary butyl peroxide, and thinning to 75% solids with a mixed solvent of butyl carbitol and pine oil. Alternatively, the resin may be a vinyl toluenated maleic modified oil prepared from maleic anhydride and linseed oil. The metal object to be coated may be a phosphated mild steel panel.

Abstract: 1410984 Colour television SONY CORP 1 Dec 1972 [7 Dec 1971] 55549/72 Heading H4F A PAL colour television receiver uses a one (or three, or five ... ) line delay line 3 and a switch 2 operated at the end of each line period to produce a chrominance signal having the same modulation axes for all line periods, which chrominance signal is passed to demodulators 6, 7; the phase of operation of switch 2 is controlled so as to pass to the demodulators 6, 7 a chrominance signal having desired modulation axes (in the embodiment shown having the R-Y modulation axis at + 90 degrees relative to the B-Y modulation axis) by the use of further demodulators 13, 14 receiving the received chrominance signal from band-pass amplifier 1 and the delayed chrominance signal from delay line 3, respectively, which, in combination with adder 17, subtractor 20, envelope detectors 18, 21 and differential amplifier 19 produce an output from control circuit 22 if the phase of operation of switch 2 is wrong, thus producing a change in the state of a flip-flop 5 which controls switch 2. A subcarrier reference signal of phase equal to that of the bursts in the chrominance signal fed to demodulators 6,7 is produced by an oscillator 10, the correct reference signals for demodulators 6, 7 being produced by 45 degree phase retarder 11 and 90 degree phase retarder 12. The reference signals for demodulators 13, 14 are derived from 90 degrees phase retarders 15, 16. If the switch 2 is operating correctly, no output is derived from control circuit 22 and the operation of flip-flop 5 is not altered. Demodulators 13, 14 may be supplied with only the bursts contained in the chrominance signals derived from 1, 3 respectively, and these demodulators may be supplied with reference signals of other phases, e.g. phase retarder 15 may be omitted (Fig. 13, not shown). Demodulator 7 may receive the received chrominance signal from amplifier 1 rather than the chrominance signal from switch 2.

In a frequency-shift data transmission system amplitude modulation is avoided by arranging that the frequency shifts always occur at a precise phase angle of the carrier. In the arrangement shown the oscillator 4 feeds a level detector 5, e.g. a Schmitt trigger, which produces an output pulse each time the oscillator passes a predetermined level, i.e. at a precise phase angle. This pulse is differentiated (6) and rectified (7) and fed to the AND gates 1 and 2 which allow the input data at terminal 1 to be fed via a level discriminator 8 to the bistable 3 which controls the frequency of oscillator 4.
