Title: Device for indicating the number of times an internal combustion engine has been started and stopped
IPC: F02B77/08
Filed: 1959-05-04
Abstract: 904,051. Lubrication indicators. CALIFORNIA RESEARCH CORPORATION. May 4, 1959 [May 8, 1958], No. 15254/59. Class 12 (3). [Also in Groups XIX and XXVII] A device for indicating the number of times an engine has started and stopped, thereby indicating when an oil change is desirable, comprises a counter 10, Fig. 1, actuated by means, such as a bi-metallic coil 21, responsive to successive temperature change cycles caused by starting and stopping. The device is mounted on a bracket 15, Fig. 4, above the exhaust pipe 33 and in the path of cooling air from the fan 35 so that the coil 21 rotates the counter operating shaft 14 to advance the counter by one numeral each time the exhaust pipe becomes hot, the cooling air rapidly cooling the coil 21 when the engine is stopped to rotate the shaft 14 in the opposite direction, which has no effect on the counter. The coil 21 is attached to a slot in the shaft 14 and is held in position by a pin 28 having an arm 29, extending through a slot 30 in the casing 23, by means of which the counter can be reset to zero. Rotation of the shaft 14 by about 35 degrees advances the counter by one numeral and under very cold conditions the coil 21 rotates through about 70 degrees on each starting operation so that the counter is advanced by two numerals to take account of the more rapid deterioration of the oil at low temperatures.

Title: A method of separating stearine from mixtures of fatty acids containing oleine and unsaponifiable material
IPC: C11C1/00
Filed: 1947-06-12
Abstract: <PICT:0650720/III/1> Stearine is separated from mixtures of fatty acids containing oleine and unsaponifiable materials by dissolving the warmed mixture in liquid hydrocarbons, cooling the solution to a temperature between 0-10 DEG  C., and separating off the stearine formed by filtering in vacuum filters.  The original mixture is warmed to a temperature of about 50 DEG  C.  The solvent may be removed from the stearine and liquid portions by evaporation. The stearine may be purified by washing it with the hydrocarbon followed by separation and drying as before.  A complete repetition of the extraction process followed by the washing treatment may be performed to give a stearine product of high purity.  In a suitable plant, the solvent from a storage tank 2 is pumped to a solvent supply tank 8 and the warmed fatty acid mixture from a storage tank 1 to a mixing vessel 9 or 10 to which the solvent is fed from tank 8, preferably in equivalent proportions.  The solution is then released through valve-controlled outlets 19 or 20 into an endless carrier-cooler apparatus 23, composed of two parallel sections 231 and 2311, where the solution is cooled to a temperature between 0-10 DEG  C., the stearine crystallizing out.  From the cooler the mixture is fed to a vacuum filter tank 26 or 27 equipped with heater filters 36, 37.  The filtrate containing oleine and unsaponifiable materials is drawn off to a collecting tank 38 where the solvent is evaporated, led to a cooler 40 and returned to the solvent supply tank 8.  The stearine on the filter plates of the filters 26 or 27 is washed with fresh solvent supplied to spray pipes 30 or 31 arranged in the top of each filter tank and connected to the solvent supply tank 8.  The filtrate is again drawn off to the collecting tank 38, and the solid stearine on the filter plates heated and the molten mass drawn off to a collecting tank 44 where it may be dried by evaporation.  The whole of the above plant may now be duplicated, solvent supplied to the stearine in tank 44 and the resulting solution re-treated as above, the doubly separated and purified stearine being finally collected in a receiver 63.  Vacuum is maintained throughout the system by a pump 65 connected to the solvent supply tank 8.
