Title: Apparatus for registerin transversely corrugated elements
IPC: B23K1/002
Filed: 1973-02-23
Abstract: 1406932 Making corrguated tubular elements; soldering NORTHERN ELECTRIC CO Ltd 23 Feb 1973 [24 Feb 1972] 9093/73 Headings B3A and B3R Apparatus for registering transversely corrugated strip with a transversely corrugated tubular element comprises a pair of co-operating rolls 12, 12a, each having a periphery of concave profile and forming a nip having a generally circular opening which accepts the strip and tubular element when in contact and forces their corrugations into correct register. A corrugated tube 10 is formed from, e.g. a copper/ tinned steel laminate, which is formed into a longitudinally butt jointed tube. A butt strap 13 is formed from tinned steel strip 14, which is transversely corrugated by rolls 15 and is fed into the nip of the rolls 12, 12a. The joint in the tube is aligned with respect to the rolls 12, 12a by a peripheral rib (37) in a grooved roller 11, Fig. 3 (not shown). A solder strip 17 is fed through a fluxing station 18 and into the nip of the rolls 12, 12a between the strap 13 and the tube 10. As the strap enters between the roll 12a and the tube 10 it is bent to arcuate shape by a peripheral groove (36) in the roll 12, Fig. 3, and the corrugations of the butt strap and tube are forced into registry. The tube and strap pass into a soldering member 25, where the solder is melted by a heating coil 26, after which the tube is cooled in a trough 27. The tube is finally wound up after soldering. Resilient clamps hold together parts 28, 29 of the soldering member 25, which is supported on the tube thereby holding the tube and strap together to give an effective joint. The rolls are eccentrically mounted on stub shafts (40), Figs. 4, 5 (not shown) and rotation of the stub shafts relative to the rolls moves the rolls of a pair toward or away from each other. The tube cross-section is maintained circular by the rolls and it may be used as an outer conductor for a co-axial cable. The rolls may overlap the edges of the tube to form a lap joint.

Patent GB-350603-A (GB)
Title: Improvements in the manufacture of ferro-nickel magnetic alloys
IPC: C22C1/02
Filed: 1930-03-21
Abstract: Magnetic alloys consisting mainly of iron and nickel have their permeability increased and electrical resistance decreased by melting the constituent metals of high purity in contact with an amount of carbon sufficient to prevent oxidation and insufficient to raise the carbon content above 0,05 per cent.  The alloys may contain 35-95 per cent of nickel, preferably 45-55 or 70-80 per cent, and may contain also about 1 per cent of manganese and in some cases up to 10 per cent of copper, with the balance mainly iron.  The total of the usual impurities such as carbon, silicon, sulphur, phosphorus should not exceed 0,50 per cent.  In making the alloys, good grades of iron and nickel are melted with enough charcoal to produce 0,02-0,03 per cent of carbon in the molten metal.  On melting the metal is covered with a slightly reducing slag consisting preferably of lime, fluorspar, and tarcoke, the coke being graded or regulated so as not to carburize the metal, and about 0,25 per cent of manganese is added under the slag to assist in desulphurizing and dephosphorizing the melt.  The temperature is raised and an alloy of silicon with an alkaline-earth metal or with a heavy metal such as zirconium, tungsten, or uranium, or with magnesium, is added to deoxidize.  A calcium or zirconium alloy may be used for the 45-55 per cent nickel alloys and a magnesium alloy for the 70-80 per cent nickel alloys. The magnesium alloy is conveniently added in alloy with a heavy metal, as for example a nickel alloy containing 25 per cent of silicon and 5 per cent of magnesium.
Patent GB-622772-A (GB)
Title: Improvements in or relating to coloured colloid layers
IPC: G03C1/825
Filed: 1947-04-03
Abstract: 622,772. Colour photography. WALLER, C., DICKINSON, H. O., and ILFORD, Ltd. April 3, 1947, No. 9144. [Classes 97 (i) and 98 (ii)] Coloured colloid layers are produced by treating a substantially colourless colloid layer, containing colloidal silver selenide in such small quantities that substantially no colour is imparted to the colloid layer, with a solution of a reducing agent in the presence of another silver compound and a solvent therefor. When forming part of a photographic material the colloid layers may contain a silver compound such as silver halide or may be adjacent to a silver halide emulsion layer. Reduction is effected as by a photographic developer in the presence of a solvent for the silver compound such as potassium thiocyanate or sodium sulphite, the colour produced being yellow to red, or brown. Layers containing the colloidal silver selenide may be made by adding to a colloid such as gelatine or other protein, polyvinyl alcohol or hydrophilic cellulose derivatives, a selenium compound such as selenourea, allyl selenourea and selenosulphates and a silver salt such as the nitrate or halide and heating for a short period. The layers are of particular value as filter layers in colour photography, and a multilayer material may comprise a transparent support carrying red-, green- and bluesensitive silver halide emulsion layers with two interposed layers according to the invention, that between the green- and blue-sensitive layers being coloured yellow with a fugitive dyestuff or by inclusion of yellow colloidal silver. The material may also include subbing, antihalation and antiabrasion layers and an ultraviolet absorbing layer. The exposed material is developed in a developer containing a silver solvent when the two interposed layers both become coloured. The emulsion layers may be selectively processed to colour by reversal colour development with the aid of the filter layers by successive blue light exposures on each side of the material and by rendering the middle emulsion layer developable by exposure to very bright light or X-rays or by fogging with sodium arsenite, hydrogen peroxide or guanidine thiocyanate. The first formed negative silver images may be removed by acid dichromate or permanganate before re-exposure, the silver selenide being unaffected by this treatment. On treating the final product with Farmer's reducer, all the silver and silver salts are removed, to leave a colour picture. Example 1 describes a three-emulsion film and its development to colour, the colour formers being contained in the final developers, and example 2 a film and process in which the redsensitive layer itself contains a colour former, the details being the same as those of examples 1 and 2 of Specification 595,582, except that the sulphides of that Specification are replaced by selenides. Specification 505,099 also is referred to.
