Title: Metal working lubricating compositions
IPC: C10M173/00
Filed: 1952-07-18
Abstract: A lubricating composition for metal working comprises a major proportion of water and minor proportions of a nitrate, a buffering agent and a water-soluble or water-dispersible non-ionic surface-active agent of formula R-(XR1)y-XXR11 wherein R and R11 each represents a hydrogen atom, a hydrocarbon group or an acyl radicle, R1 represents an alkylene group, X represents oxygen, sulphur, selenium or tellurium, and y is an integer greater than 1, the grouping XR1 being the same or different on each occasion on which it occurs in the molecule.  The nitrite may be a metal nitrate or a nitrite of an organic base, particularly of an organic nitrogen base. The buffering agent may be an alkali metal or alkaline earth metal acetate, citrate, tartrate, phosphate, tripolyphosphate or molybdate. Minor proportions of anti-foaming agents, masking agents for masking objectionable odours, and/or perfuming agents may be present in the composition.  Examples of anti-foaming agents are silicones (e.g. dimethyl silicone polymer), organic phosphates (e.g. tributyl phosphate) and polyglycidyl isopropyl ether.  Examples of masking agents are low molecular weight aldehydes (e.g. acetaldehyde), oil of pines and oil of mirbane.  The composition may be emulsified with oil and in this case an emulsifier may be present.  Suitable emulsifiers are oil-soluble salts of petroleum sulphonic acids, alkali metal soaps of fatty acids, of rosin acids or of naphthenic acids, alkali metal salts of sulphated alcohols, and alkali metal salts of mono- and poly-alkyl esters of sulpho-dicarboxylic acids.  A large number of examples are given wherein the nitrite is sodium nitrite, lithium nitrite or dicyclohexylammonium nitrite; the buffering agent is disodium hydrogen phosphate, trisodium phosphate, potassium tripolyphosphate, borax or sodium molybdate; the non-ionic surface active agent is "Pluronic F68", "Pluronic L64", "Ucon 50-HB-1000" ("Ucon" is a Registered Trade Mark), "Ucon 50-HB-660", reaction product of polyoxypropylene glycol with ethylene oxide, monobutyl ether of reaction product of polyoxypropylene glycol with ethylene oxide, water-soluble polyoxyethylene polyoxypropylene glycol, water-soluble copolymer of ethylene oxide and propylene oxide or the monopropyl or monolauryl ether of such a copolymer; and other ingredients present in some cases are silicones, tributyl phosphate, polyglycidyl isopropyl ether, mineral oil and sodium petroleum sulphonate.  Tests are described in which the lubricating compositions of the invention are compared with compositions consisting of (a) n-butanol, sodium nitrite, trisodium phosphate, potassium ricinoleate and water, (b) water, "Antarox A-400" ("Antarox" is a Registered Trade Mark) and disodium hydrogen phosphate, with or without sodium mercaptobenzthiazole, thiourea or lauryl pyridinium chloride, (c) water, "Antarox A-400", and sodium nitrite, with or without thiourea, and (d) water, "Antarox A-400" and borax.

Title: Improvements in or relating to the engine controlling means for motor vehicles

Filed: 1933-06-28
Abstract: 405,184. Regulating. MAYBACHMOTORENBAU GES., Friedrichshafen-on- Bodensee, Germany. June 28, 1933, No. 18440. Convention date, July 1, 1932. [Class 7 (vi).] In order to obviate running of the engine of a motor-car continuously at a normal or low speed during free-run periods, and thereby permitting undue power for lighting &c. to be drawn from the storage batteries or other power reservoirs, auxiliary means adapted to function when the fuel control is released are provided for raising the idle or free-running speed of the engine from the normal to a higher value whenever the speed of the car itself exceeds a predetermined amount, the engine in such circumstances being employed for charging &c. purposes. In the arrangement shown, the normal free-running speed is determined by means comprising a liquid pump 3 driven from the crank shaft 1 and circulating liquid through an adjustable port 8 regulated by a set-screw 9. Should the engine speed exceed a selected minimum value, the pressure in front of the port 8 rises and a sliding piston valve 39 is actuated, thereby venting to atmosphere, through a port 12 and pipe 11, a chamber 13 in which a partial vacuum is normally maintained by connection to the induction pipe 24. A piston 14 and rod 16 are thereby moved downwardly and permit a spring 19 acting on the released accelerator pedal 20 to actuate the throttle 18 in a closing direction. The normal free-running speed of the engine can thus be set to any desired amount by adjustment of the set-screw 9. Coupled to the driven shaft 4 is a second pump 6 which circulates liquid through an orifice 31 regulated by set-screw 30 and arranged so that, when the car speed exceeds the pre-determined amount selected, the pressure behind the orifice 31 is diminished, and a piston 33 and rod 36 are moved downwardly to open a second valve 37. As this valve provides an additional passage from the space 7 associated with the part 8, the free-running speed of the engine is adjusted to a new and higher value, which can be determined by the provision of a third set-screw 38. The screws 9, 30, 38 thus fix the two free-running speeds of the engine, and the car speed at which the change from one speed to the other occurs. Means may be provided for automatically throwing the auxiliary control out of action when not required, e.g., to prevent over-charging of the batteries &c.
