Title: Preparation of suspensions of water-soluble solids in oleaginous media
IPC: C09K23/00
Filed: 1958-10-31
Abstract: Suspensions of water-soluble solids in oleaginous media are obtained by emulsifying an aqueous solution of the solid, preferably of a concentration of 20-70% by weight, with the oleaginous liquid to form a water-in-oil emulsion, using an autocondensate of 12-hydroxystearic acid as the emulsifying agent, and thereafter dehydrating the emulsion.  The oleaginous media which may be used include mineral oils, such as lubricating oils, residues, a fuel oil or kerosene, vegetable oils such as castor oil, or synthetic oils, such as a diester, a polyglycol, a polyether, or a silicon-containing synthetic oil; if lubricating oil is used, the final product may be mixed with a grease, or thickened to a grease with a grease-forming agent.  The water-soluble solids to be used include corrosion inhibitors such as alkali metal and ammonium nitrites, carbonates, bicarbonates, sulphites, borates, chlorates, perchlorates, hypochlorites, silicates, phosphates, salicylates, citrates, tannates, lactates, tartrates, oxalates, phthalates, acetates, arsenites, iodates, chromates, molybdates and tungstates, and amine nitrites, phosphates, and iodates, and extreme pressure agents such as hydroxy fatty acids, polycarboxylic acids, hydroxy polycarboxylic acids, organic salts, e.g. sodium benzoate, amides and amino acids.  The amount of water-soluble solid in the final suspension is generally 0.5-25% by weight.  The emulsifying agent, which should have an acid value not above 100, and preferably not greater than 50, and a saponification value at least 50, and preferably at least 100, units greater than the acid value, may be prepared by heating 12-hydroxystearic acid to 150-250 DEG C.  In the example the condensate was so produced at 180 DEG C. after 12 hours, having an acid value of 41 and a saponification value of 168.  The condensate, which is used in amounts of 0.1-10% by weight of the oleaginous liquid, is generally first dissolved in the oil, the aqueous solution added, the mixture stirred and/or milled to produce an emulsion, and the emulsion thereafter dehydrated, for example by heating to 115-170 DEG C., with continuous stirring to prevent frothing.

Abstract: 768,859. Pivotal joints. WHITE, C. S. Dec. 7, 1954 (Dec. 8, 1953], No. 35379/54. Class 65 (2). [Also in Groups XXXII and XXXIV] In a pivotal joint assembly, bearing means of heat responsive resin material is moulded in place wholly between relatively movable inner and outer parts, after assembly, under heat and pressure conditions, the parts themselves constituting the forming dies. As shown, the bearing means is in the form of two substantially hemispherical cups interposed between the head 33 of a ball stud and a housing which consists of two parts 54, 55. Each cup is of laminated construction, the inner layer 48 of which consists of cotton netting formed with from 6 to 10 threads per inch and being loaded with from 10 to 30 per cent by weight of graphite. Alternatively, the inner layer may be formed from a sheet of " Oilite " (Registered Trade Mark) perforated at closely spaced intervals. An intermediate layer 51 is formed of 12-ounce cotton flannel material impregnated with a phenolic resin, the pile side of the flannel facing the inner layer so as to penetrate the spaces in the latter and make contact with the surface of head 33. The outer layer may be either a single sheet of resin-impregnated cotton duck of about 6 to 10 ounce material, or it may be in the form of a layer 52 of canvas having a backing layer 53 of " neoprene " secured thereto. The cup elements are first placed in the respective housing parts 54, 55 and may be cemented thereto by a thermosetting material. The pre-heated ball stud is then assembled within the housing, and the members of the latter are clamped upon the stud to establish a pressure of approximately 2000 pounds per square inch between the parts. The housing members are then secured together and the assembled joint is finally subjected to a temperature of from 300 to 350 degrees Fahrenheit for about 5 minutes to cure the phenolic resin. For joints carrying light loads, the flannel layer may be omitted. The frictional characteristics of the joint may be controlled by varying the temperature and pressure, and by suitable selection of the material used in the outer layer. If desired, lubricant may be forced into the housing and the latter sealed by a " neoprene " boot 60.

Abstract: 290,238. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Gilson, R. M.). May 11, 1927, [Convention date]. Protective arrangements; switching systems.- In alternating current supply arrangements involving conductors 10, 11 in a metal sheathed cable and a relay R actuated from said conductors through a control conductor 14, which may also be in the cable, faulty operation of the relay due to grounding of the control conductor is prevented by reactive devices connected between one or both of the power conductors and ground. Fig. 1 shows inductive resistances X<1>, X' which by shunting the capacity C<1>, C<2> between power conductors and ground prevent the occurrence of sufficient voltage across the capacity C' of the conductor 11 to operate the relay. Fig. 6 shows an arrangement by which the potential of the ground G is made to equal that of the conductor 11 by the provision of a condenser C<3> equal in capacity to the capacity C<2> of the conductor 10, connected to the terminal 30 of a secondary winding of the supply transformer, the conductor 11 being connected to its centre and the conductor 10 at its opposite terminal. The continuance of the protection described is assured by relays 19, 22 normally held open by the current in the reactive devices which current is in each case rectified by full wave rectifiers 18, 21; the relays close a bell circuit when an open or short circuit occurs in a reactive device.

Title: A system for circulating liquid under pressure through the space between two relatively slidable surfaces
IPC: F16C29/02
Filed: 1955-12-09
Abstract: 812,929. Machine framings; lubricating- passages. GENDRON FRERES S.A. Dec. 9, 1955 [Dec. 18, 1954], No. 35461/55. Class 83 (3). [Also in Group XXXIV] A system for circulating pressure fluid such as lubricant between two relatively slidable surfaces, for example a machinetool table and a slideway, has means for maintaining constant the clearance between the two surfaces, involving the circulation of lubricant through a reference circuit having a predetermined resistance to the flow of lubricant. As shown in Fig. 1, a slideway 2 of a machine tool has grooves 3 for admitting lubricating oil, which is fed through a duct 4 from a distributer 5 supplied with oil under constant pressure from a duct 21. The distributer comprises a cylinder 11 fitted with a hollow piston 14 containing nozzles 16, 17 at its ends. The piston has an annular groove 18 normally connecting the duct 21 with the duct 4, but with a restricted inlet from the groove into the duct 4. One end of the cylinder 11 is connected by a duct 7 to a recess 6 in the slideway 2, and the other end is connected by a return duct 9 by a passage between a cylindrical recess 23 and a disc 24. The disc 24 is adjustable, and the clearance between the disc and the edge of the recess 23 is set to be equal to the clearance X between the annular edge of the control recess 6 and the table 1. With this arrangement the piston 14 has equal pressures at the ends when the oil is supplied through duct 21, and is located symmetrically in the cylinder 11. If the clearance X is reduced, the pressure in the compartment 12 increases so that the piston 14 is moved to the right and the inlet to the duct 4 is increased, permitting an increased flow of oil through the duct. This acts to restore the clearance X to its original value. If the table 1 travels further than the recess 6, the pressure in the duct 7 drops, so that the piston 14 moves to close completely the inlet to the duct 4 and prevent supply of oil to the grooves 3 until the table once more covers the recess 6. In a modification, Fig. 3, the disc 24 is replaced by a needle valve 24, and the portion of the piston adjacent the inlet to duct 4 is of frusto-conical form. The grooves 3 and recess 6 may be combined together, as shown in Fig. 5, the piston 35 having two frusto-conical edges co-operating with edges of grooves 38, 39, fed from the supply duct 21. The compartment 13 is fed from the groove 39 through an inner passage 43 of the piston. In a further modification, Fig. 6, a single edge 46 of the piston cooperates with the inlet 47 leading to the lubricating duct 48, and also co-operates with a duct 49 leading to the compartment 13 and the needle valve 24<SP>1</SP>. The piston has two narrow passages 51, 52 connecting the end compartments 12, 13 with the annular groove 18 at the centre of the piston.
