Title: Improvements in or relating to electric switches
IPC: H01H33/66
Filed: 1927-07-26
Abstract: 276,641. Scherbius A., and Ritter, E. R., (trading as Scherbius & Ritter). Aug. 26, 1926, [Convention date]. Bases; cases. - A switch has its contacts working in an exhausted vessel and the mechanical movement of the contacts effected by forces outside the switch transmitted to the contacts through the medium of a resilient part of the vessel. In Fig. 2, a copper vessel 1 has a corrugated diaphragm 2 and is fused to a glass foot 4, the whole being evacuated or fitted with a neutral gas so that only minute movements of the contacts are required for breaking large currents. An operating member 15 welded or soldered to the diaphragm acts on an extension of one contact 13 by means of a glass rod 16, but in a simpler form (Fig. 1, not shown) the moving contact is mounted on the diaphragm which is moved by an external hook thereon. Thermal switches.-Such a hook is shown at 25 in Fig. 3 on a switch 18 on a bracket on a plate 19 which also carries an iron bar or a bar 23 of the material known under the registered Trade Mark Invar adjustable by means of a wheel 26. Increase of temperature causes the plate 19 to expand, whereas the bar 23 retains its original length, the hook 24 moves into engagement with the hook 25 to open the switch 18. The Specification sets out in detail the advantages of mounting the thermal elements externally of the switch, such advantages being in brief (1) the use of materials having large expansions but unsuitable for use in a vacuum owing to occluded gases. (2) the use of beat for attaining a high vacuum. (3) the smallness of the vessel. (4) the heat sensitive member can be put in direct connection with the apparatus to be regulated, and (5) the ease of adjustment of the heat sensitive member. Other means of actuation are by air, steam, or water pressure, or by magnetic relays, and the invention is also applicable to vibrating rectifiers, buzzers and other apparatus having a high rate of oscillation, the latter being facilitated by the relatively small movements possible in an evacuated vessel, and consequently small energy required.

Title: Improvements in or relating to corrosion resistant coated metal members and method of making the same
Inventor: SCHUSTER LUDWIG KARL
IPC: C23C22/30
Filed: 1954-07-13
Abstract: Nitric acid which has been used to etch iron is purified by being passed through a granular bed of a cation exchange resin. The resin may be of the sulphonated polystyrene type containing -SO3H groups and, when saturated with iron, may be regenerated with sulphuric acid.ALSO:A method of producing a coated metal member comprises applying to the metal, or to a pre-formed oxide film thereon, an aqueous solution of chromic acid, and a water-soluble reducing agent to reduce the chromic acid, said reducing agent being applied either together with or after the chromic acid, and curing the coating at a temperature of at least 212 DEG F.  The coating should weigh 3-200 mg./sq. ft. and have 40-95 per cent of its chromium in the trivalent form.  The following metals may be coated: aluminium, copper, nickel, magnesium, tin, zinc, and steel an example of which contains C .04-.12 per cent, S .015-.05 per cent, P .015-.14 per cent, Cu .02-.2 per cent, Mn .2-.6 per cent, Si trace-.08 per cent.  Metal members referred to are firearm parts, camera bodies, toys, venetian blind slats and cans for food or chemicals: a method of soldering the latter is disclosed using an ammonium chloride-hydrochloric acid flux (Fig. 3, not shown).  The oxide film may be produced by treatment with nitric acid (to which may be added urea), nitric acid + hydrofluoric acid, ammonium persulphate, picric acid, ferric nitrate, or sodium hydroxide + sodium nitrate; pre-treatment in a non-oxidizing etchant (of which a number of examples are disclosed), prevents the metal becoming passive during the nitric acid &c. treatment.  The reducing agent for chromic acid may be a polyalcohol such as invert sugar, sucrose, dextrose, glycol and polyethylene glycols, glycerine, mannitol, sorbitol, triethanolamine, hydroxylamine and its salts e.g. the sulphate and hydrochloride, phosphorous acid, or potassium iodide.  An oxide of a Group VI metal is preferably incorporated in the coating, e.g. by adding molybdenum oxide to the chromic acid solution; compounds of other metals, such as titanium and vanadium, can also be added.  The solution may also contain (i) a manganese compound to prolong its life (ii), zinc, calcium or strontium chromate, and (iii) a wetting agent.  The coating is preferably cured at 250-350 DEG F. and then quenched in water containing 0.03-1.0 per cent chromic acid: it may be protected by an electrostatically applied film of oil.  The coating is stated to provide a good substrate for subsequent application of varnish, lacquer &c.
Patent GB-925071-A (GB)
Title: Beverage flavors and process for their production
IPC: A23L27/28
Filed: 1959-06-15
Abstract: A beverage flavour resembling in flavour and aroma chocolate, coffee, tea and the like, is produced by heating in a vessel a hydrous mixture of a proteinaceous substance and a saccharide to achieve rapidly an elevated temperature of at least 350 DEG  F., enclosing the gaseous constituents developed to maintain the hydrous condition, maintaining the conditions for a holding period sufficient to develop flavour and, upon development, rapidly reducing the temperature of the reaction liquor to a temperature at which flavour development is arrested.  The flavour employed either alone or in combination with other flavour and aroma constituents such as astringency and bitterness factors, has an aroma and taste suitable for beverages, food products, icings, confections and candy.  The term "proteinaceous substance" is defined as either a protein in pure form or any proteinaceous material capable of producing among its decomposition products a free protein, and protein hydrolisates containing peptides or amino acids, but excludes yeast, the use of which in the process is described and claimed in Specification 925,072.  The term "saccharide" is defined as a reducing sugar or saccharide capable of reducing Fehling's solution to give cuprous oxide, or any saccharide and other material which provides a reducing saccharide under the conditions of reaction; many specific examples are given.  According to an example, 78 g. peanut meal, 78 g. wheat bran, 44 g. sucrose, 13.2 g. calcium carbonate and 1000 ml. water were thoroughly mixed and then placed in a 2-litre reaction autoclave.  The reaction mixture was brought to the atmospheric boiling point, the autoclave was then sealed, and the reactants were heated with continuous agitation to 350 DEG F. in 26 minutes and to 400 DEG  F. in an additional 6 minutes; this was followed by immediate quenching to 240 DEG  F. in 4 minutes and reduction to room temperature in a total time of 13 minutes.  The reaction liquor was filtered, and the filtrate was diluted to form an aqueous solution of 2% solids concentration.  Calcium carbonate or other buffering agent (specified) may be included in the reaction mixture so that the flavour solution shall have a pH within the preferred range of 4.5 to 5.2, whereby curdling of cream to which it may be added is avoided. In other examples there were employed as the proteinaceous substance, hoof keratin, chicken-breast meat and histidine, respectively.
