Patent GB-806595-A (GB)
Title: Improvements in or relating to lubricating oil detergent
IPC: C10M125/18
Filed: 1955-03-25
Abstract: A stable dispersion of a basic metal compound in an oil-soluble surface active agent is produced by hydrolysis of a metal halide which has been uniformly distributed through the surface-active agent.  A homogeneous mass comprising the surface active agent, the metal halide, and a solvent may be treated to remove the solvent and then subjected to hydrolysis.  Suitable halides are the chlorides of cadmium, calcium, strontium, barium, magnesium, or zinc; boric acid, phenol, formic acid, or acetic acid may be added to assist the hydrolysis.  Many suitable surface active agents are listed; these include alkyl and alkaryl sulphonates, mahogany or petroleum soaps, tri- and pentavalent organic phosphorus acids, thiophosphorus acids, and their salts, phosphorus sulphide-treated olefins and their salts (e.g. as described in U.S.A. Specifications 2,316,080 and 2,516,119), metal soaps of naphthenic and higher fatty acids, non-ionic agents of the polyglycol type, and cationic agents of the amine or quaternary ammonium type.  The salts and soaps are formed from alkali and alkaline earth metals.  The solvent may be methanol, ethanol, a propanol, butanol, or pentanol, or water.  In examples: (1) a solution of calcium chloride and boric acid in n-butanol is mixed with a refined hydrocarbon pale oil and a solution of polydodecylbenzene sulphonic acid in hexane; after heating to evaporate the butanol and hexane, steam is passed through the mixture at 200 DEG  C. to effect the hydrolysis; (2) a solution of zinc chloride in methanol is mixed with sodium polydodecylbenzene sulphonate in oil, the methanol evaporated, and the product hydrolysed with water at 150 DEG  C.; (3) an aqueous solution of barium chloride and formic acid is mixed with sodium polydodecylbenzene sulphonate in oil, the water evaporated, and the product hydrolysed with water at 150 DEG  C.; (4) an aqueous solution of cadmium chloride and boric acid is mixed with calcium polydodecylbenzene sulphonate in oil, the water is evaporated, and the product hydrolysed with steam at 200 DEG  C.; (5) a solution of magnesium chloride in ethanol is mixed with potassium polydodecylbenzene sulphonate in oil, the ethanol evaporated, and the product hydrolysed with steam at 200 DEG  C.  In each example the final product is centrifuged and yields a bright fluid dispersion in which the size of the dispersed inorganic particles is less than 1 micron.  The dispersions may be added to lubricating compositions (e.g. a mineral lubricating oil containing a small amount of added phosphorus pentasulphide-treated wax olefin) as detergents and corrosion inhibitors.  Specification 789,820 also is referred to.

Title: Improvements in automatic weighing machines
IPC: G01G13/24
Filed: 1921-03-23
Abstract: 177,401. King, H. J. H. March 23, 1921. Automatic-feed weighers.-Relates to automatic weighing-machines for liquids and finelydivided materials, of the kind comprising a compartmental rotary drum mounted at one end of a counterweighted weigh-beam, the drum rotating automatically when a compartment has received the required weight of material so as to discharge the filled compartment and bring the next compartment into the filling position, and consists in providing means whereby the continuous feed of the material is transferred automatically from the filled to the succeeding compartment with only a momentary stoppage of feed. As shown, the drum 1 is rotatably mounted between the arms of a forked weighbeam which is supported upon a knife-edge 5 carried by the frame of the machine. A link 12 connects the beam to the feed-hopper 10 which is supported upon knife-edges 11 and adapted to swing over a bridge 15 secured to the frame. Stops 18 secured to alternate compartments on each end of the drum engage with spring catches 17 secured to the frame and prevent the rotation of the drum during the filling operation. In use, with all the compartments empty, the hopper is vertical and feeds into the compartment a. When the required weight of material has passed in the compartment, the drum falls and the hopper swings over the bridge 15 thus momentarily cutting off the feed and thence discharging into the succeeding empty compartment f. Owing to the extra weight of material in the compartment f, the drum becomes disengaged from its catch and rotates so as to discharge the compartment a and bring the compartment f under the hopper which has now returned to its vertical position. A recorder of known construction may be operated by a lever 20 from the weigh-beam.
