Abstract: 1,247,563. Mercury chloro-alkali or diaphragm chlorate cells. HOOKER CHEMICAL CORP. Nov. 22, 1968 [Dec. 4, 1967], No. 55493/68. Heading C7B. Hypochlorite is removed from the cell liquor of a mercury chloro-alkali or disphragm chlorate cell by contacting it externally of the cell with an ethylenically unsaturated compound to produce chlorohydrin, or, by further reaction with caustic alkali, a glycol and/or polyol, and recycling the treated liquor. For a diaphragm chlorate cell, the treated liquor may be passed to crystallizer from which the mother liquor containing the product of reaction, e.g. ethylene glycol, and make-up feed brine is recycled to the anode compartment of the cell, the product being sacrificially oxidized at a graphite anode in preference to carbon so reducing its oxidation. Similarly, depleted mercury cell brine, containing the product after reaction with the ethylenically unsaturated hydrocarbon, may be reconstituted preferably after dechlorination and neutralizing with alkali metal (e.g. sodium) chloride and recycled to the mercury cell where the product serves to decrease graphite anode oxidation and reduce the amount of hydrogen evolved with chlorine in the cell. The unsaturated compound is preferably an aliphatic or a cycloaliphatic hydrocarbon of C 2-8 , e.g. ethylene, propylene, 2- methyl-propene, 1- or 2-butene, 1, 3-butadiene or pentadiene and/or 1, 4-pentadiene.

Abstract: 563,315. Indicating temperature and water levels. SMITH, S. J. March 5, 1943, No. 3659. [Class 40 (i)] [Also in Group XXXVI] A compensated moving coil comprises a single coil movable in a magnetic field set up in part by a permanent magnet and in part by an electromagnet, the field due to the electromagnet opposing that due to the permanent magnet. If the moving coil 25 is connected in a D.C. circuit in series with a resistance and the field coil is connected across the circuit the effect of changes in voltage is neutralised. As shown in Fig. 3 for use as an ohmmeter the coil 31 is tapped so as to form two arms of a bridge, of which the other two arms are the resistance 33 and the resistance to be measured, such as a resistance thermometer which is connected between terminals 35, 36. A direct current supply is connected to terminals 37, 38 across one diagonal of the bridge whilst the moving coil 25 is connected across the other diagonal. Fig. 4 shows the application to a liquid level gauge. Liquid containers 41, 42, 43 are each provided with a rheostat 44 operated by a float 45. The terminals 35, 36 of the ohmmeter are connected with the rheostat 44 by means of a switch 47 so that either of the rheostats or all in series may be connected. Resistances 49, 50, 51 are connected in series with a resistance 46 to balance the bridge at zero liquid level. The ohmmeter may be calibrated in terms of liquid level so that the contents of each container or the total contents of all the containers may be indicated. Where measurements are effected by using a change of inductance or capacitance to control an alternating current, the currents applied to the instrument are rectified. Specification 563,316, [Group XXXVI], is referred to.

Abstract: 1,207,140. Power dividers. WESTERN ELECTRIC CO. Inc. 19 Dec., 1967 [28 Dec., 1966], No. 57549/67. Heading H1W. [Also in Division H3] A power divider comprises two circulators having a common arm provided with a shunt or series capacitative reactance. The figure shows two strip-line, 3 port circulators 24, 25 of known form having respective arms 28, 29 of equal length coupled to each other by a series capacitance. The capacitance is provided by a conductive disc 33 mounted upon a threaded dielectric rod for movement towards and away from a gap between the ends of the arms. If the directions of circulation of circulators 24, 25 are clockwise and anticlockwise respectively, energy applied to input port 1 is wholly divided in phase quadrature between output ports 2 and 3, the ratio of power division depending upon the value of the (adjustable) coupling capacitance. Further, displacement of the coupling from the central position between the circulators changes the phase relation between the outputs. In particular, a displacement of one eighth wavelength towards one or other of the circulators brings the outputs into phase opposition. In a modification (Fig. 4, not shown), the coupling is in the form of a displaceable shunt capacitance. In this construction, the arms 28, 29 are conductively joined and the adjustable disc 33 is connected to the ground plane 20 by a conductive threaded rod. The latter engages a slot in the ground plane which enables the disc to be adjusted to various positions along the common arm 28, 29. It is stated that a relative phase variation ranging over 360 degrees is obtainable. The circuit may be used for balanced mixers, modulators and frequency converters by terminating ports 2, 3 with appropriate non-linear elements and applying inputs to both port 1 and port 4. The directions of circulation may be changed with consequent permutation of the output/input ports. A varactor diode may be used for the adjustable capacitance, or an inductance may be used instead of a capacitance.

A tape for use in brazing includes a base of hard flexible non-porous plastics material which carries a coating of powdered brazing alloy fixed to the base by an air-hardening binding agent which is miscible and unreactive with the base and which completely vaporizes on heating. To produce the strip, a liquid mixture of 1 part cellulose acetate to 3 parts of acetone is brushed on the periphery of a rotatable ring, the periphery being constituted by a copper backing with a chromium, ceramic or glass base enamel face, the coating is allowed to dry and at least partially to harden and a finely dispersed brazing alloy is fed from a hopper above the ring on to the coating while a liquid mixture of 1 part acrylic resin to 4 parts trichlorethylene is simultaneously sprayed on to the coating to fix the alloy. The trichlorethylene vaporizes and the alloy and acetate coating are cut transversely of the ring and peeled off. A release agent in the form of a high temperature brazing flux may be sprayed on to the cellulose acetate coating and allowed to dry before the resin and alloy are applied. Just prior to brazing the cellulose acetate base can be peeled off the tape taking most of the flux but leaving the alloy and resin. The parts are placed in a jig and a portion of the tape is placed between them and brazing in a spot welding machine is effected. The parts are placed in a furnace to complete the brazing. The resin vaporizes. The alloy may be of approx. 82% gold and 18% nickel; in which case pure nickel powder may be secured to the free side of the acetate base by resin to provide in the joint an alloy of higher melting point, the composite tape being inserted between the parts to be brazed. Other brazing alloys are 85% silver, 15% manganese; 3À5% silicon, 1À9% boron, 94À6% nickel; 4À5% silicon, 2À9% boron, 92.6% nickel; 10% silicon, 20% chromium, 3% iron, 67% nickel; 80% gold, 19% copper, 1% iron; 62À5% gold, 37À5% copper; 37À5% gold, 62À5% copper; 30% gold, 70% copper and 75% gold, 25% nickel. Instead of cellulose acetate, vinyl plastics, styrol resins, resinamines, acrylate polymers may be used and instead of acrylic resin, vinyl plastics. The tape may be passed over a pinned roller to provide perforations after being removed from the ring.
