Title: Improvements in metal working lubricant solutions
IPC: C10M173/02
Filed: 1952-09-26
Abstract: "Bi-metallic" salts of alkylene diamine polycarboxylic acids, particularly ethylene diamine tetra-acetic acid, are described having two of their four carboxylic groups neutralized by an alkali metal ion, such as Li, K, Na and Cs, and the remaining carboxylic groups neutralized by a metal ion other than an alkali metal ion; the second metal ion may be an alkaline earth metal ion, such as calcium, or lead, cadmium or copper.  The disodium mono-calcium salt of ethylene diamine tetra-acetic acid may be prepared by dissolving one molar weight of the tetra amino acid in water with two molar weights of NaOH and digesting the solution at a warm to hot temperature with one molar weight of freshly precipitated calcium hydroxide, and then evaporating to dryness.ALSO:A metal-working lubricant comprises an aqueous solution of a bi-metallic salt of an alkylene diamine poly-carboxylic acid having two of its carboxylic groups neutralized by an alkali metal ion and the remaining carboxylic groups neutralized by a metal ion other than an alkali metal ion.  The alkylene diamine polycarboxylic acid may be ethylene diamine tetra acetic acid, and the alkali metal ion may be lithium, potassium, sodium or caesium.  The solution may be used in wire-drawing of base metals, such as iron, nickel or copper, or their alloys.  The second metal ion of the bi-metallic salt may be above or below the metal being drawn in the displacement series of metals in aqueous solutions of the salt.  In the former case the second metal ion may be an alkaline earth metal.  An example is the di-sodium mono-calcium salt of ethylene diamine tetra-acetic acid.  An aqueous solution of the salt may be used per se but preferably contains a soap, such as sodium stearate, in substantially equal proportions; the solutions may have densities between 0.98 and 1.1.  When the second metal ion is displaceable by the metal of the wire being drawn, it may be lead cadmium or copper.  Aqueous solutions of these salts may be used per se, but preferably contain a soap, such as sodium stearate, with the salt in large excess of the soap.  For beryllium-copper alloy wires the salt may be the di-sodium mono-cadmium salt of ethylene diamine tetra-acetic acid. For all the solutions the water is preferably deionized with the tetra-sodium salt of ethylene diamine tetra acetic acid.

Title: Rotary vibrator and mount therefor
IPC: B06B1/10
Filed: 1973-05-22
Abstract: 1397173 Vibrators C G MATSON 22 May 1973 [13 Oct 1972] 24404/73 Heading F2X A rotary vibrator is interfitted with a mounting structure, the vibrator casing and the mounting structure having co-operative cam surfaces adapted to continuously tighten as a result of the migratory rotative movement of the vibrator ensuing from the continuing driving force applied to the vibrator rotor, thus providing a simple automatic clamping of the vibrator to the mounting structure. The invention is described with reference to a vibrator similar to that forming the subject-matter of Specification 1,094,466 and comprising a casing 10 having an interior circular track 12 within which a rotor 14 is confined by the track and by a pair of side plates (not shown). The track has an annular groove 20 to which compressed air is supplied via a tangential port 22 and an inlet 24. The side plates have annular grooves 28 provided with exhaust outlets 30. One or more mounts typified by the mounting structure 34 are affixed to the article 32 to be vibrated, e.g. a concrete mould, as by welding at 36. The structure 34 includes a tube 38 so shaped and dimensioned that the casing 10 fits initially relatively loosely within it. The tube 38 in cross-section takes the form of a 3-lobed cam with three high spots 40 and three low spots 42. The exterior of the casing 10 has three co-operating ram surfaces formed by lugs 46 welded to the casing. When the vibrator is started and after the user has given the casing a slight counterclockwise turn by means of a handle (not shown), the precessive or migratory movement of the casing causes the co-operative cam surfaces to continuously tighten, the resultant wedging or tightening action being maintained so long as driving force is applied to the vibrator. Where several tubular mounts are provided, one vibrator may be easily and simply moved from one mount to the other.
