Abstract: 1512032 Photo-electric signal transmission D H SCHAEFER and J P STRONG 16 April 1975 [8 May 1974] 15639/75 Heading G1A A digital radiant-energy signal array system, for selectively moving an input signal array an arbitrary amount in response to an input command signal, comprises: an output array for providing digital radiant-energy signal elements; a source of command signals; and means responsive to the command signals to enable the spatial position of the output array to differ from that of the input array. The description is identical with that of Specification 1512031, and the figure numbers given below in brackets refer to those used in the abridgment of that Specification. In a shift device 324, Fig. 21b, an array of input signals carried by an optical fibre bundle 314 is duplicated by a device 316 (also Fig. 10) one copy being transmitted directly to a first combiner 340 (also Fig. 10), the other copy being displaced by a predetermined number of columns (or rows) in a slider Snx (also Fig. 20), and then transmitted to a second combiner 350. Each combiner 340, 350 feeds a respective first or second AND gate 344, 354 (also Fig. 1) connected to an input of a third combiner 348 which provides, via an OR gate 360 (also Fig. 3) an output array to a fibre bundle 328. An array of command signals carried by an optical fibre bundle 326 is duplicated at 330, one copy being transmitted directly via the second combiner 350 to the second AND gate 354, the other copy being inverted by an inverter 336 (also Fig. 8), then applied via the first combiner 340 to the first AND gate 344. This inversion of one copy enables the presence or absence of command signals to act in complementary ways on the AND gates 344, 354, enabling one and inhibiting the other, so that the output of the OR gate 360 is either a direct or a displaced replica of the input array at 314. A cascade of n devices 324, shown at 302, 304, 306, Fig. 21a, each for shifting an input array by a different number 2j of places, may be selectively commanded by signals 308, 310, 312, to shift an array by any number of places up to (2<SP>n</SP>-1).

Title: Improvements in and relating to method of treating iron or mild steel to promote theadherence of porcelain enamel, and stock so produced
IPC: C23D3/00
Filed: 1950-06-22
Abstract: Iron or mild steel is treated to improve the adhesion of vitreous enamel by depositing a coating of nickel thereon, subjecting it to a scale anneal, at least equivalent to that obtained by heating in an atmosphere of burned natural gas containing 11 per cent combustibles and a dew-point of 150 DEG F, at 1550 DEG F for 2 minutes, and then removing the scale by pickling. The nickel coating may be formed by deposition from a 30-40 per cent solution of nickel sulphate or by electrodeposition.  The scale anneal may be a normalizing treatment in air, or may consist in holding at 1700-1800 DEG F for 40 seconds and cooling to 900 DEG F in 2 minutes in an atmosphere containing 9 per cent carbon dioxide, 5 per cent carbon monoxide, 12 per cent hydrogen and the balance nitrogen.  The pickling solution may be a 6-25 per cent solution of sulphuric acid at 160-190 DEG F.  The metal may be decarburized at any stage in the process and may be given a final flash coating of nickel by chemical deposition before coating with a single layer of white or light-coloured vitreous enamel.

Filed: 1925-06-17
Abstract: 235,888. American Rubber Co., (Assignees of Teague, M. C.). June 18, 1924, [Convention date]. Latex, treating.-A thickened and stabilized latex for spreading, dipping, moulding, &c. purposes is obtained by adding to latex a thickening-agent which would normally, by its decomposition, produce a coagulating-agent, and checking such decomposition by the addition of a suitable reagent in order to avoid coagulation. For example, the thickening-agent may be sodium or potassium silicate, which becomes hydrolyzed, forming sodium hydroxide which acts as a coagulant. Ammonia or a substituted ammonia is therefore added to prevent hydrolysis and to preserve the latex from coagulation. An example of a composition according to the invention consists of 100 parts of rubber (as latex), 100 parts of whiting, 300 parts of ground flint, 25 parts of zinc oxide, 85 parts of water, 100 parts of sodium silicate, 15 parts of ammonium hydroxide, 30 parts of sulphur, and 2.5 parts of tetramethyl thiuramdisulphide.

Title: Improvement in porcelain enamel article and method of producing same
IPC: C23C18/36
Filed: 1950-06-27
Abstract: Steel work pieces are prepared for porcelain enamelling by cleaning and roughening the surface so as to produce deep, sharp-edged pits therein, immersing the roughened steel in an aqueous solution of a nickel salt containing sodium hypophosphite as a reducing agent whereby the nickel salt is reduced and nickel deposited on the steel without ion exchange between the steel and the solution, maintaining the immersion until the nickel deposit is about 0.1 to 0.2 gm. per square foot, washing, and drying, and a cover coat porcelain enamel which is substantially free of adherence promoting oxides is then fired directly on the coated surface (see Group XXIII).  The surface may be prepared by chemical means and/or mechanical means, e.g. sand blasting.  The chemical pickling baths which produce deeply etched surfaces may employ nitric acid with or without other acids, sulphuric acid containing nitric acid or other oxidising agents, or salts, e.g. FeCl3, which are readily reduced in the presence if iron. The preferred nickel deposit is 0.150-0.175 gm. per square foot, and 0.1625 is the most suitable.  The baths for the chemical reduction of nickel may be alkaline, containing for example in grams per litre, nickel chloride 30, sodium hypophosphite 10, ammonium chloride 50, sodium citrate 100, and ammonium hydroxide to a pH of 8 to 10, or acid, composed for example in grams per litre of, nickel chloride 30, sodium hypophosphite 10, sodium acetate 10, the pH being 4 to 6 The steel is immersed for about one minute at about 70 DEG C., and then washed in warm water.  The process for enamelling cold rolled steel is described.
