Abstract: Metallic surfaces, esp. iron and steel, are chemically treated to produce coatings which support lubricants, e.g. mineral, animal and vegetable oils and greases and soap, for e.g. wire drawing, stamping, deep drawing and metal spinning, by immersing the metal to form a phosphate layer, then withdrawing the part from the bath and allowing the soln. to dry without prior rinsing, thus leaving a second layer contg. inorg. salts superimposed on the first phosphate layer. The soln. consists of 5-200 g/l alkaline or ammonium phosphates, 0-20 g/l oxidising agents, 0-10 g/l reducing agents, 0-20 g/l activators, 0-300 g/l inorg. cpds. for the reinforcing layer, and surface active agents at pH 3-6, and temp. >50, pref. >80 degrees C. The oxidising agents may be nitrates, chlorates or bromates, or org. nitro cpds. The reducing agents include hydroxylamine, activators used include molybdates, vanadates, nickel, cobalt or copper salts, simple or complex fluorides. The addns. for the sec. inorganic layer may include alkaline, chlorides, sulphates, nitrates, fluoborates and/or fluosilicates and insol. inorg. suspensions such as bentonites, graphite, pyrophosphates of iron, zinc, tin or magnesium, mica, etc. The use of these coatings extends the life of the tools and allows a faster and easier prodn.

Title: Belt clamp for metal strip during cutting - has multiple V=belts in parallel around pulleys rotated at slightly different speeds
Inventor: LEVY LOUIS MARCEL
IPC: B65H23/04
Filed: 1976-11-30
Abstract: The clamping and tension arrangement for strip of metal plate to be cut comprises a group of trapezoidal straps or belts (14) which form an endless strip. The component belts can be displaced at the same or slightly different speeds. At least two groups of wheels (3, 6) on adjacent parallel shafts (1, 5) are provided, around which the belts or straps (14) are wound. The wheels on the first shaft are so fitted that they can rotate independently of each other, and have a circumference groove to take the belts. The wheels on the second shaft are blocked against rotation, but can be freely moved axially. Each second group wheel has an inclined profile in its circumferential area. Thus two half profiles of the two neighbouring wheels form a trapezoidal shaped groove to take a belt.

Title: Liq. acidic phenolic resin condensn. prods. - useful as curing agents for thermosetting resins, made by reacting a sulphonated phenol aldehyde resin, urea and formaldehyde
Inventor: NOVAK VIKTOR ALEXEEVICH
IPC: C08L61/34
Filed: 1976-12-14
Abstract: Liq. phenolic resins with poor solubility in water are useful as curing agents for thermosetting resins. The resins have a liq. consistency at +10 to -30 degrees C and are made by condensing (a) a sulphonated cpd. with a liq. consistency over 25 degrees C, made by sulphonating 1 mol. phenol and 0.05-0.29 mol aldehyde; (b) urea or its derivs. and (c) formaldehyde in a mol. ratio (a):(b):(c) of 1:(0.1-1.0): (0.1-1.0). The prods. are viscous, rose to cherry red liquids (1-100 p at 20 degrees C) with a weak phenolic smell and an acid value of 50-350 mg KOH/g. They are easily soluble in alcohol, acetone and DMF. The liq. consistency is retained at +10 to -30 degrees C. The resins are formed at relatively low temps. so that decomposition of the urea during the process is avoided. Resins are useful as (room temp.) curing agents for phenolic, urea and melamine aldehyde resins, furan resins, etc., and esp. for foamed resin insulation materials.
