TL;DR: In this article, a thixotropic, grease-like composition consisting essentially of a nonvolatile diluent oil, an oil-soluble dispersing agent, an alkaline earth metal carbonate and a minor amount of a polymer was presented.
Abstract: This disclosure concerns compositions comprising a major amount (e.g. at least 75 weight percent) of a thixotropic, grease-like composition consisting essentially of a nonvolatile diluent oil, an oil-soluble dispersing agent, an alkaline earth metal carbonate and a minor amount (e.g. 0.1 to 25 weight percent) of a polymer. The composition is particularly useful as a lubricating grease and also is useful as a rust inhibitor.

29 Jun 1970TL;DR: A grease composition containing a polysiloxane, the organic substituents of which are primarily methyl radicals and C6 to C20 alkyl radicals, a thickener, and zinc naphthenate was used to lubricate door hinges on houses and automobiles.
Abstract: A grease composition containing a polysiloxane, the organic substituents of which are primarily methyl radicals and C6 to C20 alkyl radicals, a thickener, and zinc naphthenate. The presence of the zinc naphthenate in the grease provides corrosion resistance to iron and iron alloy metal surfaces to which the grease is applied. The composition may be prepared by heating the polysiloxane and the thickener together at a temperature of about 240* C with mixing, cooling the mixture partially, adding the zinc naphthenate during the remainder of the cooling period, and then milling the resulting material. The grease composition was used to lubricate door hinges on houses and automobiles.

TL;DR: In this paper, a mechanism and method for conditioning grease before it is deposited into a digester is described, where the grease is heated by heating coils in order to melt it so that when the grease was deposited into the digester, the enzymes will digest all of the grease.
Abstract: The present invention relates to a mechanism and method for conditioning grease before it is deposited into a digester. The grease is heated by heating coils in order to melt it so that when the grease is deposited into the digester, the digester enzymes will digest all of the grease. Preferably the grease solids are separated from nongrease solids prior to the melting step and are maintained in a separated condition until such time as the grease is ready to be digested. The grease is maintained in the liquified condition while it is transported from the heating tank to the digesters. Agitating means comprising injection of compressed air into the heating tank is used to prevent the grease from insulating the heating coils during melting.

TL;DR: A mechanical greasing apparatus is reservoir, for lubricating heavy machinery as discussed by the authors, which consists of a grease reseroivr, a piston cylinder arrangement coupled to the grease reservoir, which is adapted to deliver a continuous flow of grease, and a grease pipe connected to the arrangement to receive the continuous flow from the arrangement.
Abstract: A mechanical greasing apparatus is reservoir, for lubricating heavy machinery. The apparatus comprises a grease reseroivr, a piston cylinder arrangement coupled to the grease reservoir, which is adapted to deliver a continuous flow of grease, and a grease pipe connected to the piston cylinder arrangement to receive the continuous flow of grease from the piston cylinder arrangement. The piston cylinder arrangement is usually operated by an electric power motor.
TL;DR: An improved W.I.R.A. as discussed by the authors was devised with features which reduce or eliminate the main faults of the W. I. R. A. apparatus with scoured wool, and the R5 instrument is sufficiently sensitive to distinguish between small discrepancies in residual wool grease found on different sections of a tuft.
Abstract: In an investigation of the W.I.R.A. rapid grease-extraction apparatus, it was found that up to 20% of the methylene chloride extract of scoured wool could evaporate away at the heater mantle. This loss and others contributed to the low, and erratic results usually obtained when using the W.I.R.A. apparatus with scoured wool.An improved instrument (R5) has been devised with features which reduce or eliminate the main faults of the W.I.R.A. apparatus.The experimental investigations consisted of the extraction (with methylene chloride) of residual wool grease from scoured wool. Using four types of wool having residual wool-grease contents in the range 0.3-7%, the percent extrac tion from the Soxhlet, R5, and W.I.R.A. instruments have been compared. Highly significant linear relationships were found between the extract amounts from the R5 and Soxhlet apparatuses. The R5 instrument is sufficiently sensitive to distinguish between small discrepancies in residual wool grease found on different sections of a tuft...

Abstract: A plunger assembly is provided for slidable engagement with the plunger rod in hand grease guns, which grease guns are adapted to use both cartridge-packed grease and bulk-loaded grease. The plunger, in cross section, is of essentially W-shaped configuration and comprises a sleeve having a bore formed therethrough for slidably receiving the rod. A transverse web is carried by the forward portion of the sleeve and extends radially outwardly and, at its periphery, is attached to an interior support section which extends outwardly and rearwardly of the web to proximate the inside diameter of the grease barrel. An annular flexing and sealing wall is carried by the periphery of the support section and extends outwardly to beyond the inner diameter of the grease barrel and then forwardly and inwardly to a position forward of the sleeve and inward of the inner diameter of a grease cartridge. An annular lip is formed on the inner side of the wall and engages washer means between the lip and the forward portions of the transverse web.

TL;DR: In this paper, it is shown that the addition of TsIATIM-339 to silica gel greases reduces the oxidation stability of the greases but increases their strength.
Abstract: 1.
The resistance of silica gel greases to oxidation is determined largely by the stability of their liquid base. Despite the high chemical stability of Si greases in silicone liquids (with respect to the change in the acid number), they cannot be considered resistant to oxidation owing to the marked changes in the tensile strength.
2.
The resistance of the grease to oxidation is markedly improved by adding to the oil silica gel, rendered hydrophobic by butanol; the improvement increases with the gel concentration. In contrast to soap stiffeners, silica gel is an inhibitor of oxidation.
3.
It is shown that addition of the multifunctional additive TsIATIM-339 to silica gel greases reduces the oxidation stability of the greases but increases their strength.
4.
Diphenylamine is an effective antioxidant for silica gel greases; its optimum content in greases in lube oils is 1.0 wt.%.

TL;DR: Grease has many advantages as a ball and roller bearing lubricant, such as it is easily retained in the bearing housing, can be used at quite high rotational speeds without leaking and also acts as a protective coating against corrosive attack as discussed by the authors.
Abstract: GREASE has many advantages as a ball and roller bearing lubricant. For example, it is easily retained in the bearing housing, can be used at quite high rotational speeds without leaking and also acts as a protective coating against corrosive attack. The latter naturally depends on the quality of the grease but this article only considers products of repute.
TL;DR: In this article, it was shown by differential thermal analysis, infra red spectroscopy and electron microscopy that corrosion inhibitors with such an influence structurally change the soap, and these analytical methods can consequently be used for rapid evaluation of possible long time interaction.

TL;DR: In this article, metal chelates of N,N,N-disubstituted dithiooxamide were investigated for their potential as grease thickeners.
Abstract: Metal chelates of N,N′-disubstituted dithiooxamide were investigated for their potential as grease thickeners. It was found that three selected materials did thicken fluids to grease consistencies. The three materials were: N,N′-dimethyldithiooxamido cobalt (N,N′-DMDTO Co), N,N′-dimethyl dithiooxamido zinc (N,N′-DMDTO Zn), and dithiooxanilino zinc (DTOA Zn). The dithiooxamides have been found to be an excellent new class of thickeners. They demonstrate high thermal and oxidative stability and are efficient thickeners for a wide variety of synthetic fluids. It is shown that a two-component grease system can be prepared from them and will function as an extreme-pressure, antiwear grease without the introduction of other additives.
