Abstract: 1312289 Thermocouples VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE AG 12 Oct 1970 [16 Oct 1969] 48418/70 Addition to 1250975 Heading H1K The thermocouple arrangement of the main patent, in which a replaceable unit comprising a capillary tube containing the thermocouple secured to an insulating sleeve carrying a coaxial socket is positioned within a metal or metal-ceramic sheath, is modified by enclosing the capillary tube in a gas tight tube which is also secured to the insulating sleeve, the thermo junction being spaced from the closed end of the gas tight tube. As shown, thermocouple wires 15, 16 extend through a capillary tube 11 at the lower end of which they are joined to form the hot junction 12. The capillary tube is surrounded by a gas tight tube 10, the upper end of which is secured to an insulating sleeve 21 carrying a coaxial socket 17 to which the ends of the thermocouple wires are connected. The capillary tube is also secured to the sleeve 21 by means of a filling 22 of casting resin or gum. Alternatively the coaxial socket and the upper ends of the capillary and gas tight tubes may be inserted in a mould and secured together by casting resin which also forms the sleeve 21. The above assembly constitutes a replaceable unit which is placed inside a sheath 6 comprising a metalceramic end portion 7 and a steel upper portion 8 which is secured to the end of a water cooled lance 1 by means of a nut 9. A spring 24 is provided to ensure that the end 13 of the gas tight tube 10 is in good thermal contact with the end 27 of the sheath 6. A coaxial plug 18 connected to compensating leads 19 is inserted into the socket 17 and a refractory jacket 5 is releasably secured to the assembly. The gas tight tube may be filled with a protective gas. The device may be utilized for continuous measurement of the temperature of a molten metal.

Filed: 1975-10-31
Abstract: 1516976 Electo-optic modulator PLESSEY CO Ltd 31 Oct 1975 [8 Nov 1974] 48338/74 Heading G2F An electro-optic modulator assembly includes a modulator M, Fig. 6, comprising a slice K, Fig. 4, of crystalline lead lanthanum zirconate titanate located between two parallel transparent plate electrodes P1, P2, and a mounting m for the modulator which permits the modulator to be rotated about an axis perpendicular to a beam L from a laser Y, whereby the light is directed obliquely through the slice. The plate electrodes are made of indium oxide and tin oxide. If polarizers W1 and W2 are placed in front of and behind the modulator assembly with their planes of polarization perpendicular, modulation is demonstrated by the presence of light on screen Z when the modulator has light incident obliquely thereon.

Title: Improvements in or relating to bleaching
IPC: D06L4/26
Filed: 1962-12-27
Abstract: A bleaching composition comprises a solid mixture of ammonium, an alkali metal or an alkaline earth metal chlorite with a stabilizing and actuating quantity of one or more water soluble salts of one or more alipthatic or aromatic carboxylic acids, e.g. sodium benzoate, acetate, citrate, formate, propionate or oxalate.  The composition may contain the carboxylate and chlorite in the molar ratio of carboxylate to chlorite of from 0.02 : 1 to 0.17 : 1.  The composition may also contain wetting agents, e.g. nonyl-phenyl-polyethylene glycol ether containing 4 molecules of ethylene oxide per molecule and the sodium salt of diisobutyl naphthalene sulphonic acid, corrosion-preventing agents, buffer substances, e.g. disodium hydrogen phosphate, and optical bleaching agents, e.g. stilbene derivatives.  The compositions may be produced by simply mixing the components together, by spraying a solution of the additional components on to the ammonium or alkali or alkaline earth metal chlorites and then drying or by spray-drying a solution of the components.  Liquid bleaching concentrates, which upon dilution may be used to bleach cotton cloths, may be obtained by dissolving the solid composition in water.

Title: Improvements in ramp type analogue to digital converters
Inventor: DOREY HOWARD ANTHONY
IPC: H03M1/00
Filed: 1967-10-27
Abstract: 1,220,091. Dual ramp digital voltmeter. SOLARTRON ELECTRONIC GROUP Ltd. 4 Oct., 1968 [27 Oct., 1967], No. 48988/67. Heading G4H. In a dual ramp digital voltmeter of the type in which an integrator circuit is first charged for a reference period and then discharged to the datum level, the integrator is discharged by two reference signals. In the embodiment of Fig. 1 a switch 16 is closed by a bi-stable 10 on receipt of a start pulse so that the integrator is charged up, a switch 18, connecting a clock 19 to a counter 15, being simultaneously closed. When the counter is full, bi-stable 10 is reset to open switches 16 and 18 and set a bi-stable 11 which closes switches 20, 21, 22 so that a reference signal - V R  discharges the integrator. A detector 24 resets the bi-stable 11 when the output of the integrator is V 1 . Whilst bi-stable 11 is set pulses are accumulated in the decades sections of counter 15. Resetting of bi-stable 11 sets a bi-stable 12 to connect the output of the integrator to a zero detector 28 and to connect a reference signal - V R/10  to the integrator, pulses being counted in the units section of the counter until the output of the integrator is 0. In a modification (Fig. 3, not shown), when switch 20 is operated to connect in V R  a further switch (32) is changed over so that a capacitor (14) in the integrator circuit discharges through a resistance (23) to reduce the output of the integrator by a small amount. When the integrator output reaches zero a further switch (37) switches over so that the integrator output rises to V 1  and then continues to discharge at a slower rate defined by the reference - V R/10 . In a second modification the output of the integrator is allowed to overshoot the zero level and a reference signal of + V R/10  is then applied to the integrator, pulses being subtracted from the units section of a bi-directional counter until the level detector again detects 0. Alternatively, if a unidirectional counter is used the output of the first decade will be wired to give the complement of the count.

Filed: 1971-11-09
Abstract: 1363892 Echo sounders SIMRAD AS 9 Nov 1971 [10 Nov 1970] 52076/71 Heading H4D Echo sounding apparatus comprises a receiver with two amplifiers having different time varied gains, a threshold detector at the output of one of the amplifiers causing an output circuit to be switched over from one amplifier to the other amplifier when an echo signal of sufficient magnitude or rise rate is received. A transmitter 1 feeds transducer 2 and resulting echo signals are received by transducer 3 and pre-amplifier 4. Amplifier 4 feeds amplifiers 5 and 6, the gains of which are varied with depth r (and hence time) of reflections according to (40 logr+2αr) and (20 logr + 2αr), respectively, α being the attenuation constant. The former function is suitable for fish echoes and the latter for bottom echoes. The variable gains are initiated by a pulse from 1 which also triggers a bi-stable 10. The output from 10 opens gate 7 and allows amplifier 5 to feed output circuit 11. At the same time, gate 8 is closed. In this condition, amplifier 5 is operative and gives optimum gain variation for fish echoes. When a bottom echo is received, threshold detector 9 will give an output and resets bi-stable 10, closing gate 7 and opening gate 8. The bottom echo signal therefore passes through amplifier 6, having an optimum gain for such signals, and hence to output circuit 11. Amplifier 6 remains operative until the next pulse from 1, which repeats the cycle.
