Title: Improvements in lubricating oil compositions
Filed: 1948-02-05
Abstract: A composition comprising a major proportion of lubricating oil contains, as corrosion inhibitor, a minor proportion of benzyl thiocyanate.  The lubricating oil may be of animal, vegetable, marine, mineral or synthetic origin.  The composition may be employed as a lubricant especially where water is normally or accidentally present, as in the case of reciprocating steam engines, steam turbines, boiler pumps, gear boxes or cases, especially the differentials and transmissions of automobiles and crankcases of internal combustion engines.  The composition is noncorrosive towards metals and is particularly effective with iron and other ferrous metals.  It maintains its efficacy even when corrosive substances are present in the composition, so that the composition may contain such corrosive ingredients as extreme pressure agents, pour point depressors, sludge inhibitors and oiliness agents.  Extreme pressure agents mentioned are free sulphur in solution and substances containing sulphur and/or halogen.  Sulphur-bearing E.P. agents specified are sulphur-containing or sulphurized petroleum fractions, organic sulphides or polysulphides, mercaptans, thio-acids and thio-esters, while halogen-bearing E.P. agents specified are the halogenated aliphatic or ring compounds mentioned in U.S.A. Specifications 1,986,651 and 2,137,782, halogen-bearing esters, acids or salts, and halogenation products of such petroleum fractions as mineral oil, foots oil, kerosene and paraffin wax. Of the various halogen-bearing E.P. agents, those containing chlorine are preferred. Oiliness agents mentioned are oxygen-bearing organic compounds, particularly those formed by the oxidation of petroleum fractions. In the examples (1) a gear lubricant consists of mineral gear oil, benzyl thiocyanate, chlorinated paraffin wax and dibenzyl disulphide; (2) a turbine lubricant consists of mineral lubricating oil, benzyl thiocyanate, hexachlor diphenyl oxide and tri (methyl cyclohexyl) phosphite, with or without o-dichlorbenzene; and (3) a crankcase lubricant consists of mineral lubricating oil, benzyl thiocyanate and methyl chlorsalicylate.  Details of corrosion tests are also given in which the effect of the addition of a small amount of benzyl thiocyanate to the following compositions is shown: (a) mineral lubricating oil together with chlorinated paraffin wax and either benzyl disulphide or kerosene disulphide; (b) mineral lubricating oil together with chlorinated cyclohexane and chlorbenzyl disulphide; (c) mineral lubricating oil together with chlorinated naphthalene and benzyl disulphide; (d) mineral lubricating oil together with one of the following: the mono dichlorstearate of ethylene glycol, methyl chlorsalicylate or a mixture of methyl and ethyl dichlorstearates. Specification 514,052 also is referred to.

IPC: B61D27/00
Filed: 1927-02-09
Abstract: 290,339. Stone &. Co., Ltd., J., prestige, J. T., and Bridcut, S. H. Feb. 9, 1927. Driving-gear, regulating. - Ventilation - apparatus for railway and other vehicles comprises a rotary blower b movably supported on or suspended from the undercarriage of the vehicle and driven by a transmission from a running-axle a, and means ane provided for automatically preventing the blower output from rising unduly with increase in speed and for shutting-off the blower action when desired. The blower b is pivotally suspended by a link d<1> on a pivot d, the weight of the blower being operative for tensioning a belt e running over a pulley f on the axle a and a pulley g on the blower spindle. The belt tension may be adjustable by a member h. The suction pipe of the blower is fitted with a valve m. A centrifugal governor device 3, Fig. 2, may be fitted on the blower spindle for operating cams 4 adapted for bringing about a gradual closing of self-opening flap valves 2 in the blower intake as the speed increases. Another automatic control means illustrated in Fig. 4 consists of a vane device 7 fixed to a revoluble ported disc 6 mounted on a ported partition 5 in the blowerdelivery pipe t. A spiral spring 9 on the hub of of the vane device 7 acts on an arm 10 on the disc 6 to maintain the ports in the disc and partition in register and therefore fully open. Delivery of air causes the vane device and disc to be rotated in a direction to close the ports. A streamline shield 13 may be fitted on the hub on the vane device. In the modification shown in Fig. 5 a ported disc 6 and vane device 7 are spaced apart on a spindle 15, which is carried in the blower-delivery pipe t by means of brackets.17 in the form of curved blades shaped to impart axial direction to circularly-moving air currents. A further modification of the control means consists of flap valves 18, Fig. 8, pivoted in the duct t and maintained in the fully open position by springs 19. Air flowing in the direction of the arrows tends to close such flaps against the action of the springs. For driving the blower in correct direction irrespective of the direction of travel of the vehicle, an open belt e and crossed belt e<1>, Fig. 1, may be arranged on the axle pulley so as to engage either a fast or loose pulley on the blower spindle. The belt drive may slip upon the attainment of a given speed. The Provisional Specification also describes the provision of a fan having adjustable blades, the setting of which is variable, as by centrifugal means, to produce greater uniformity of delivery over a given speed range.
