Title: Surface treatment of articles of magnesium or magnesium alloys
IPC: C25D11/30
Filed: 1964-12-17
Abstract: A method of forming a protective fluoride coating on the surface of articles composed of Mg or Mg base alloys, e.g. Mg-Li, comprises the steps of immersing the articles in a 30-45% by weight ammonium bifluoride aqueous solution and passing an alternating electric current through the solution via the articles which are connected as electrodes.  The voltage of the A.C. may be progressively increased until it lies between 110 and 120 volts A.C. and be maintained at this value for at least 30 minutes after the current falls to less than 5 amps/sq.ft. of article surface. Articles may first be cleaned, e.g. with hot tetrachlorethylene vapour.  If the articles comprise Mg-Li, they may be heated to at least 200 DEG C., Li exuded as a result of the heating being removed by immersion in continuously circulating water at a temperature below 85 DEG C.  The articles are then treated in the NH4F HF, e.g. at a temperature below 27 DEG C. with continuous relative movement between them and the electrolyte. The resultant fluoride coated articles may be coated with resin, e.g. an epoxy-melamine or polyurethane, and may then be painted.  The examples are of treating Mg alloy sheet composed of 84.5% Mg, 14% Li, 1% Al and 0.5% trace metals and impurities.ALSO:A Mg or Mg base alloy article with an electrolytically produced fluoride coating (see Division C7) may be given a resinous coating, e.g. of epoxy-melamine or polyurethane, and optionally a final coat of paint or other finish.  The resinous coating may be applied in successive layers with each being dried and cured.  In Example 1, a polyurethane coating is dried and cured at 150 DEG C for 1 hour.

Abstract: 1525509 Hydrodesulphurization of heavy oils SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 22 Dec 1975 [24 March 1975] 52346/75 Heading C5E The catalytic hydrodesulphurization of heavy vanadium-containing oils is carried out in substantial absence of water vapour until the average vanadium content of the catalyst has increased by at least 5 parts by weight per 100 parts of the catalyst carrier and then is continued at a water vapour partial pressure of 0À5 to 30 bar. The hydodesulphurization can be carried out at 300-475‹ C and a hydrogen partial pressure of 30-200 bar; a product having a constant sulphur content can be produced by gradually increasing the temperature, lowering the temperature when the presence of the water vapour is commenced and thereafter again increasing the temperature. The water can be supplied by adding water to the oil, adding water vapour to the hydrogen or by adding a precursor such as an alcohol. The heavy oil feed can be a crude oil, an atmospheric or vacuum residue of a crude oil or of a product produced in the catalytic or thermal cracking of a heavy oil. The hydrodesulphurization can be preceded by a catalytic hydrodemetallization and can be carried out in one or more stages. The catalysts used in the Examples comprise nickel and molybdenum or cobalt and molybdenum on an alumina carrier having particular pore volume distributions.

Patent GB-537149-A (GB)
Abstract: 537,149. Casein and other proteins. ATLANTIC RESEARCH ASSOCIATION, Inc. Feb. 28. 1940. No. 3699. Convention date, March 7, 1939. [Class 2 (iii)] [Also in Group VI] Proteins such as casein, of low ash content, soluble in dilute acids and suitable for the production of low viscosity solutions for the manufacture of artificial wool is produced by precipitation with an enzyme (other than acid-producing enzymes such as those present in milk) and then acidulating the liquid containing the precipitate, preferably to the iso-electric point (pH 4À6-4À7). Suitable enzymes are rennet, pepsin, and peptic proteoses. Any protein present in the initial material which is not precipitated by the enzyme may be precipitated by the acidulation so as to be recovered with the enzyme-precipitated protein. The precipitate may be washed to the desired extent and a little acid or alkali may be present in the washing water, but such additions are not necessary. After the curd is. precipitated, it may be broken up by gentle agitation, and the acidulation should be effected as soon as possible afterwards. It is then separated from the whey preferably by centrifuging and may be washed in the centrifuge. For the production of artificial fibres it is preferred to wash the casein to pH above 5. The casein product is suitable also for food products and, will dissolve on heating with an edible acid, such as acetic or citric acid, setting to a clear jelly on cooling. It can be beaten to astiff state resembling meringue or marsh-mallow which if a little sodium bicarbonate is included, will be a stable foam ; a suitable final state is pH 3-4.2. The casein product may be mixed in powdered form with citric acid. When foaming action is not desired sodium acetate or citrate can be used instead of bicarbonate, and the mixture can be stabilized by adding a little  acid.

Abstract: 1280719 Semi-conductor devices SONY CORP 5 Nov 1969 [5 Nov 1968] 54266/69 Heading H1K A magnetic field detecting device comprises a semi-conductor body 2 of intrinsic, P- or N-type material having therein two P-type (or N-type) regions 4, 5 and two N-type (P-type) regions 7, 8. The regions 4, 8 carry main current electrodes 9, 12 while the regions 5, 7, which are situated on opposite sides of the main current path, are connected together via electrodes 10, 11 and connection 13. The output voltage, measured between electrodes 10 and 12, is dependent upon the magnitude and direction of an applied magnetic field, and the output voltage/field characteristic may be adjusted by placing a variable resistor either between the electrodes 9 and 10 or between the electrodes 10 and 12. The body 2 may be of Ge, Si or an intermetallic compound. In an intrinsic Ge body the P-type regions 4, 5 are formed by alloying in In/Sn alloy, the regions 7, 8 being formed from Sb/Sn alloy. The regions 5, 7 may, in a modification be situated on opposite side faces of the body 2, or all four regions may be diffused into one of the major faces.

Abstract: 1489077 Magnetic bubble generators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 Dec 1974 [20 Dec 1973] 54441/74 Heading H3B A bubble generator comprises a conductor loop L1 associated with a bubble supporting layer in the presence of a normal bias field and at least two structures P4, P5, P6 and P7 respectively defining preferred bubble locations D3 and D5, bubbles being formed by applying a first pulse to the loop L1 to reduce the net field within the loop and allow the bubble D3 at one structure to expand up to the other (Fig. 2C) (and subsequently constrict when the pulse ends, Fig. 2D) then applying a second pulse in the opposite sense to cause the bubble to split with the result that one bubble is projected to a preferred position D5 outside the loop and the other is projected to a position D4, Fig. 2A, partly within the loop. The latter bubble returns to the position D3 within the loop when the second pulse ends. The conductor L1 and permalloy overlay structures P are formed by vapour deposition. The position D3 is unstable so only two elements (P8, P9, Fig. 3, not shown) may be provided on one limb of the loop to define a stable location. In modifications, two (or more) loops sharing a common limb generate bubbles alternately on to respective output paths representative of binary ones and zeroes, the closeness of the paths assisting propagation in the presence of an in-plane rotating field and also preventing the bubble order becoming sufused. The loop may include three pairs of structures providing three output paths by division of a single bubble into six (Fig. 6, not shown).
