IPC: C23C22/80
Filed: 1955-10-06
Abstract: In a process of treating metal surfaces of iron, zinc, cadmium, aluminium and alloys in which these metals predominate, to produce phosphate coatings thereon, the metal surface is activated, prior to the application of the coating, by immersing it in an aqueous solution comprising, by weight, 0.001-0.6 per cent of lithium, present as a compound thereof, and at least 0.004 per cent of p  PO4, present as an alkali metal orthophosphate, the lithium compound and alkali metal orthophosphate having been previously dissolved in water and evaporated to dryness.  The lithium compound may be lithium chloride or lithium sulphate and the alkali metal orthophosphate may be mono potassium phosphate or disodium or dipotassium phosphate, or a mixture of orthophosphates may be used.  Titanium may be substituted for part of the lithium, or the activating salt may be combined with the titanium or zirconium activating salts disclosed in Specifications 560,847 and 587,176, respectively.  There may be added to the activator a detergent, e.g. alkaline alkali metal compounds, such as soda ash, sodium bicarbonate, sodium silicate, trisodium phosphate, sodium hydroxide and borax, alkali soaps, e.g. sodium stearates, ammonia soaps such as ammonium palmitates, amine soaps, such as the reaction product of triethanolamine with stearic acid or oleic acid (the soaps being optionally employed with a hydrocarbon solvent such as kerosene) and synthetic detergents such as fatty acid sulphates and sulphonates.

IPC: H01L49/02
Filed: 1967-06-23
Abstract: 1,190,207. Printed circuits. KERAMISCHE WERKE HERMSDORF VEB. 23 June, 1967, No. 29023/67. Addition to 1,164,635. Heading H1R. In a modification of the process disclosed in patent Specification 1,164,635, for producing thin film printed circuits, on a carrier body 1 (Figs. 1, 2) e.g. of glass, there is first vapour deposited, an aluminium base electrode 2 for a condenser. Secondly, the electrode 2 is partially covered by a dielectric layer 3 of SiO n  by reactive vapour deposition in an oxygen atmosphere. Thirdly, the assembly is tempered at a temperature of 150-500 C. Fourthly, a nickel/chrome resistance layer 7 is vapour deposited. Fifthly, conductor paths 6, contact layers 5 and a nickel/iron cover electrode 4 for the condenser are simultaneously deposited. The part of the aluminium base electrode free of dielectric is thereby coated with contact layer 5 which can be dip-soldered. As a final step therefore the cover electrode 4, contact layer 5, and conductor paths 6 are coated with tin by dip-soldering, parts not to be tinned being covered by a masking layer. In a variant of the process, instead of aluminium an iron/nickel base electrode is deposited on the carrier and is partially covered by reactively vapour depositing TiO n  dielectric 3 thereon. An oxide layer is simultaneously formed on the uncovered surface. Thereafter a nickel/chrome resistance layer is vapour deposited and subsequently and simultaneously the cover electrode 4, contact layer 5 and conductor paths 6. The part of base electrode 2 covered with an oxide layer is thereby also covered with a layer of nickel/iron. Tinning by dip-soldering is carried out as before, and the tempering step is omitted.

Abstract: 445,775. Whistles; fluid supply. THORNTON, A. A., 7, Essex Street, Strand, London.-(Amy, Aceves, & King, Inc.; 11, West 42nd Street, New York, U.S.A.) Oct. 15, 1934, No. 29447. [Class 13] [See also Groups I and XI] Fog or other foreign particles in air &c. are dispersed by wave motion produced in the atmosphere by wave-motion generators such that the frequency of the wave motion is more than approximately five thousand and less than approximately one hundred thousand cycles per second and the energy of the wave motion is sufficient to produce a pressure of more than one dyne per square centimetre at a distance of three hundred feet from the generator. Quartz Piezo-electric crystals, Rochelle salt crystals, magnetostriction oscillators, and high frequency modulation of jets of compressed air may be employed for producing the waves. The wave generators may be provided with parabolic or other reflectors, or with refractors, to direct the waves into a single beam or pencil of rays, and trunnions may be provided on the reflector to allow of directing the beam. A number of generators may be disposed in a single reflector, or each generator of a number provided with its own reflector. For crystal generators using high voltages, the crystal may be oilcovered, and a number of crystals may be used. Fig. 3 shows a number of wave generators 20, 21, 22 of the air-jet type mounted on trunnions 8 in a frame 23, the centre lines of the trunnions being at right angles to the corresponding radii of the frame, so that the beams may be projected parallel to one another or made to cross one another by swinging the generators on their trunnions. The reflectors may all be linked to a rear frame provided with a handle so that they may all be moved simultaneously, to advance or retract the common point of focus of their beams. Gas under pressure is supplied to the generators through flexible pipes connected to a common supply pipe. The whole device may be swung about a vertical pivot 38. A central opening 40 is provided to allow an observer to look along the path opened in the fog. Searchlights 41 may be incorporated in the device.
