Brine is preheated in the coil of heatexchanger ECH and partly evaporated under reduced pressure in evaporator EV1, the remaining brine is pumped through line 2 and atomized into the top of evaporator EV2 where it is further evaporated under reduced pressure by steam withdrawn from EV1 and passed, via superheater SC, into the lower part of EV2, and the vapour flowing from EV2 is condensed in heat-exchanger ECH, the condensate (desalinated water) being withdrawn by vacuum pump PV which maintains the apparatus under-reduced pressure. Salts are extracted from the base of EV2 by device 6. The temperature of the brine is less than 50‹C. in EV1 where partial evaporation is effected with or without the application of heat. If desired, EV1 may be a solar evaporator. The vapour flowing from EV2 may be bubbled through brine in one or more further evaporators before it is condensed in ECH.

Abstract: 1,233,579. Backscatter thickness gauges. ATOMIC ENERGY OF CANADA Ltd., COMMERCIAL PRODUCTS. Sept.16, 1968 [Nov.14, 1967], No.43890/68. Heading G1A. [Also in Divisions H1 and H3] The thickness of filament material is measured by detecting the degree to which radiation from a radio-active source having an energy in the range 20-60 KeV is scattered by the filament material. Gamma radiation from an I125 source 10 passes through a collimating slit 12 and falls on the filament to be measured. Scattered radiation passes through windows 13 to an ionization chamber, (see Division H1) the output of which is amplified by an FET amplifier (see Division H3) for display on a meter and recorder. The independence of the measurement of the shape and position of the filament, which together with its independence of dyestuffs therein is demonstrated by experimental results, may be improved by locating triangular masks in front of the ionization chamber windows. The disadvantages of other radiation sources such as Sr 90/Y90; Cd 109 and Am 241 are discussed.

These output emitter followers then provide a dual function as an output transistor for one current mode switch pair and as an input transistor to another current mode switch pair. The circuits of the system may include discrete components or may be integrated circuits.

Abstract: 1,257,157. Digital transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 3 July, 1970 [22 July, 1969], No. 32302/70. Heading H4P. [Also in Division G4] Binary data is represented as a two-level signal, a transition between the two levels at bit-cell centre representing 1 and at bit-cell beginning representing 0, the second 1 of 0110 being represented by the absence of a transition. In a magnetic store or data transmission system, a mid-cell transition is used for each 1 and a start-of-cell transition for each 0, except that no transistion is provided for the 0 in a sequence 10 or the odd-numbered 0's in a sequence of 0's or the second 1 in a sequence 0110. Data is encoded into this form by insertion into a 4-bit shift register, two AND gates, partially clock-controlled, responding to the shift register stages to produce pulses for l's and 0's respectively in response to the patterns -1- and -00- respectively (where "-" means "don't care") except that the first AND gate is inhibited when a further AND gate detects the pattern 0110 in the shift register and a pulse from the second AND gate causes an arrangement of latches (partially clock-controlled) to inhibit the second AND gate from producing a pulse for the next bit time. The pulses from the first and second AND gates are ORed to an output trigger. Decoding from this form is done by gating pulses derived from the transitions representing l's and 0's into respective shift registers by the on and off states of a trigger controlled from a ramp (two ramps per bit cell) the ramp generator being synchronized with the input pulses by using the latter to sample the ramps to derive an error voltage via a filter to control the frequency and phase of the generator. An output pulse is produced for each 1 bit in response to the last stage of the l's shift register, the missing 1 in the pattern 0110 being reconstituted and ORed in by an AND gate responding to stages of both shift registers.

Abstract: 1,264,958. Treating glass surfaces. PILKINGTON BROS. Ltd., D. G. LOUKES, and W. R. MALTMAN. 3 July, 1969 [15 July, 1968], No. 33676/68. Heading C1M. Glass is subjected, at a suitable temperature, to a surface treatment by which metal ions are caused to enter the glass surface, and then reduced to the elemental metal, this treatment being successively repeated with the same or different metals to build up a desired concentration of elemental metal in the glass surface. Preferably, the metal ions are caused to enter the glass electrolytically from a molten metal body which acts as the anode in an electrolytic circuit. The glass 25 may be supported on a bath 10 of, e.g., molten tin, tin alloy or bismuth, and passed beneath an anode structure 30, which comprises a plurality (e.g. 50) of anode bars 31 (e.g. of Ag or Cu) to which cling molten bodies 33. The molten body may be df Bi, alone or with Cu or Ag, or Pb (in which case anodes 31 may be of Ru). Up to 2% of Pb may be added to the other metals. The molten body 33 may be a salt, e.g. CuCl. The anode structure is disposed in a hood (not shown) in which a reducing atmosphere (e.g. H 2 , optionally -with N 2 ) is maintained. Thus, as the glass moves through the hood it is subjected to alternate ion exchange and reduction, at e.g. 750-950‹C, the bath 10 acting as the cathode. Typically, Cu<SP>+</SP> ions pass into the glass, with Na<SP>+</SP> ions passing into the bath. The Cu<SP>+</SP> ions are then reduced to Cu, the H<SP>+</SP> ions produced passing deeper into the glass at successive stages. The electrode structure may be moved instead of the glass, e.g. as shown in Fig. 3, where anode 43 is rotated or reciprocated in hollow block 40. Alternatively, the supporting molten body may act as the anode, the glass being lifted above the molten material for the reduction steps. In a further embodiment the ions may be introduced from the vapour phase, followed by the reduction. AgBr vapour may be used for this.

The photo-sensitive coating may contain a water-insoluble resole phenolic resin (see Example 2) to render a hydrophilic substrate oleophilic. The phenolic resin in the association product may be a 2, 2<SP>1</SP>-novolak resin. The photosensitizing agent may be a dichromate salt, a diazonium salt, an azido aromatic compound or a transition metal complex e.g. those formed by dissolving in a common solvent the transition metal salt such as ammonium molybdate along with a complexing ion such as citrate, tartrate and oxalate. The photo-sensitizing agent is preferably p-diazo-N, N-diethylanibine zinc chloride. The ethylene oxide polymer may be poly (ethylene oxide). The chromium trioxide component may be chromium trioxide, dichromic acid, an alkali metal dichromate or ammonium dichromate. The substrate may be cured by heating. The photo-  sensitive coating may be a self-supporting film or be coated on a support e.g. an aluminium plate.

Paint to be sprayed passes from a pressurised container 16 to the gun 28 by means of a conduit 24 and leaves the gun through a trigger controlled needle valve 132 which is adjustable by means of a screw 142 at the opposite end of the gun. A second supply conduit 30 leads air from a paint solvent container 16 which introduces droplets of solvent into the air stream to seed it. This mixture passes through a conduit 90 in the handle of the gun, through a trigger operated valve 104 and into a chamber 112. From the chamber 112 the seeded air passes between an electrode 124, which is maintained at a potential of about 5000 volts by means of an outside source 38 and an electric cable 40, and an electrode 194. The seeded air, which collects ions from this electrostatic field, passes through a tube 158 and builds up an electric charge on a probe 198 which is directly connected to an outlet nozzle 120 to produce a higher potential electrostatic field between the end of the gun and the article to be coated. After leaving the end of the tube 158 the seeded air returns via tube 156 to a part 160 from whence by passages not shown it exits from the nozzle 170 by means of passages 174 to control the spray pattern. The shape of the passage around the electrode 194 may be altered e.g. by stepping to produce an increased effect of collecting ions. The shape of the outlet tube may also be altered e.g. by cutting a 'V' notch thereon or chamfering.
