Abstract: 1377488 Phenolic-resin compositions KANZAKI PAPER MFG CO Ltd 23 Dec 1971 [28 Dec 1970] 59998/71 Heading C3R [Also in Divisions D1-D2 and G2] A colour-forming coating composition for application to a base sheet in the manufacture of recording sheets comprises particles comprising a phenol-aldehyde polymer, a phenolic monomer of the formula wherein R is C 4-20  alkyl, optionally substituted aralkyl, optionally substituted phenyl, or cycloalkyl, the weight ratio of phenol-aldehyde polymer to monomer being from 90 : 10 to 10 : 90, and a leuco dye. The phenol-aldehyde polymer and phenolic monomer may be melted together, solidified and the mixture pulverized. Alternatively, the polymer and monomer may be present as separate particles. In Examples 1-7, p-phenylphenol is melted with a p-phenylphenol-formaldehyde polymer, the mixture solidified, and pulverized in the presence of an anionic surfactant, hydroxypropyl cellulose (viscosity regulant), and water. The phenolic compounds were then mixed with an aqueous leuco dye composition comprising fluoran dyes and Rhodamine B anilide, and a styrenebutadiene copolymer latex. In Example 8, separate particles of polymer and monomer are used. In Example 9, a p-tert.butyl phenolformaldehyde condensate was melted with pphenyl phenol and the melt was solidified and pulverized in the presence of a starch phosphate ester and water. The phenolic particles were then mixed with particles of Crystal Violet lactone and benzoyl leuco methylene blue and both were then added to a styrene-butadiene copolymer latex. In Example 10, particles of premixed p-phenyl phenol-formaldehyde condensate and p-phenylphenol and Crystal Violet Lactone are mixed with mineral spirits and cyclized rubber to form a coating composition.

IPC: F02P3/08
Filed: 1968-12-23
Abstract: 1,201,410. Ignition systems. R.C. SINCLAIR. Dec.23, 1968, No.61005/68. Heading F1B. [Also in Division H3] An ignition system comprises means 11 for producing electrical pulses which is geared to an internal-combustion engine, an ignition coil 10 comprising in series with its primary winding a capacitor C6 and a controlled switching means 14 in parallel with a direct current source of voltage 12 greater than that of a battery and one or more sparking'plugs (not shown) fed by the secondary winding of the ignition coil. The capacitor C6 discharges into the primary winding through the controlled switching means 14 when the latter switches into its conductive state in response to each triggering pulse from a trigger circuit. The electrical pulses charge a triggering capacitor C8 through a diode in association with a resistor and a second diode the triggering capacitor C8 thereby applying a triggering pulse to the controlling electrode 17 of the controlled switching means 14 superimposed on a bias voltage given to the controlling electrode by a Zener diode D7. The Zener diode also serves to limit the voltage range of the triggering pulse on the controlling electrode.

Patent GB-2015213-A (GB)
Title: Power supply for computing means with data protected shut- down
IPC: G06F19/00
Filed: 1979-02-16
Abstract: Data being processed by a computer is protected on the occurrence of either a power fault condition of an intentional shut-down initiated by the computing means. In the former case, the power fault condition is sensed and provided as an anticipatory fault status signal to the computer which immediately executes a data protect routine to store data presently being processed. Subsequently, the computer issues a shut-down command to the power source. In the latter case, the computer initiates a shut-down command but executes a data protect routine prior to the shut-down command. In both cases the computer is itself connected to the power supply and governs power shut-down. The arrangement is described in connection with a computer provided on a motor vehicle to monitor vehicle parameters. Reference is also made to data compression by comparing sensed signals with stored threshold values, to a portable data collection unit allowing sensed values stored in the memories of several vehicles to be stored on tape in the portable unit, and to clock counting apparatus.
Patent GB-2017394-A (GB)
Title: Laser gyroscope
IPC: G01C19/66
Filed: 1979-03-22
Abstract: A laser gyroscope has a phased-locked loop circuit 5, Fig. 1, coupled to a frequency difference output from a laser gyroscope cavity 110. Waves of four frequencies propagate around the gyroscope cavity, each characterised by one of the two different senses of circular polarization and one of the two different directions of propagation. Output signals  DELTA f1 and  DELTA f2 are formed each having a frequency equal to the difference between the frequencies of a corresponding wave pair. The frequency difference signal  DELTA f1 for one wave pair is phase-locked to an external reference source 118, Fig. 3. A signal applied to a Faraday rotator bias coil 114 provides the frequency shifting of the wave pairs necessary to achieve a constant frequency difference  DELTA f1. The amplitude of the signal applied to the Faraday bias coil can be employed as a precise measure VOUT of the rate of rotation. Included in other embodiments, a second, external phase-locked loop comprises a voltage controlled oscillator followed by a frequency divider whereby the oscillator frequency divided by N is phase locked to  DELTA f2. An embodiment is described, Fig. 9, in which two waves only are propagated in the cavity, and the output frequency between the two is phase detected at 406 where it is compared with a reference signal from 405. The phase detector out- put provides the output signal VOUT. The detectors output additionally has a fixed bias 409 applied, is amplified, and passed through a dither switch 414 to a coil 415 controlling Faraday rotation or Zeeman line splitting. <IMAGE>

Title: Method for scrubbing material from flue gases
IPC: B01D47/06
Filed: 1979-10-01
Abstract: Flue gases are scrubbed by injecting a liquid, such as water into the gas, e.g. from a circular array 20 of sprays on the inner wall of a chimney 10 above a position 3 where the flue is turbulent, the liquid being heated by the gas to produce a mist which can trap dust and noxious materials from the flue gas. A liquid-sludge results which falls to the base 60 of the chimney 10 and can be extracted via a grate 40 into a precipitating vessel 50. The feed pipe 21 to the sprays may contain a solenoid control valve 27 which is interlocked with a boiler so as to adjust the temperature of the chimney depending on the combustion within the boiler. <IMAGE>

Title: An autoclave
IPC: A61L2/07
Filed: 1980-04-25
Abstract: An autoclave suitable for sterilising surgical and dental instruments has a pressure vessel 11 fitted with a door 15 which may be held closed by member 20 pivoted to the door and having three projecting arms 21 engageable behind abutments 18. A pressure-sensing bellows 29 expands on the internal pressure in the vessel 11 rising, to drive a lock pin 32 through an aperture provided in an arm 21a of the member 20, to prevent opening of the door. An electrically-operated solenoid valve 49 is arranged to be opened by a control timer after the interior of the vessel 11 has been at the required sterilising temperature for sufficiently long period, to allow rapid depressurisation of the vessel. Cooling of the vessel at that stage is assisted by a fan 55 which blows air thereover. A further lock pin 35 for the member 20 is withdrawn by a solenoid 37 only when the internal temperature in the vessel 11 is sufficiently low to allow safe opening of the door 15. <IMAGE>
