Title: Oil-soluble graft polymers derived from degraded ethylene-propylene interpolymers
IPC: C10M143/02
Filed: 1969-04-29
Abstract: 1,244,435. Graft polymers. LUBRIZOL CORP. 29 April, 1969 [18 June, 1968], No. 21817/69. Heading C3G. [Also in Division C5] An oil-soluble polymer contains units derived from an oxygen-containing monomer grafted on to an oxidized, degraded interpolymer of ethylene and propylene, said oxidized, degraded interpolymer having a molecular weight of 1000 to 200,000 and being formed by contacting an ethylene-propylene interpolymer having a molecular weight of 50,000 to 800,000 with oxygen at a temperature of at least 100 C. for a period of time sufficient to effect a substantial reduction in the molecular weight of said interpolymer. The interpolymer, which is preferably derived from ethylene, propylene and a minor amount of a mono-olefin or polyene e.g. a non- conjugated diene, is oxidized and degraded by bubbling oxygen or air through a heated solution of the interpolymer, or by blowing air over the surface of the solution while the solution is subjected to shearing agitation. Alternatively, the degradation and grafting are effected simultaneously. Preferred graft monomers are vinyl esters of saturated carboxylic acids, N-vinyl lactams and N-oxohydrocarbon or sulphohydrocarbon acrylamides. In examples, (a) a degraded ethylene/propylene/1,4-hexadiene interpolymer is grafted with diethylaminoethyl methacrylate or decyl methacrylate; and (b) a degraded ethylene/propylene/dicyclopentadiene interpolymer is grafted with 2-hydroxyethyl methacrylate, vinyl acetate, N-vinylpyrrolidone, methacrylic acid, diethylaminoethyl methacrylate, an ester of methacrylic with an alcohol derived from a wax having a molecular weight of about 350, N - (1,1 - dimethyl - 3 - oxobutyl) acrylamide, a vinyl ester of a saturated carboxylic acid containing about 10 carbon atoms or 2 - acrylamido - 2 - methylpropane - 1 - sulphonic acid. The graft polymer obtained using methacrylic acid is reacted with N-(3-aminopropyl) morpholine. The graft polymers are incorporated in mineral oil lubricants.

Title: Improvements in or relating to liquid level gauges
IPC: G01F23/16
Filed: 1947-08-08
Abstract: 639,477. Fluid-pressure servomotor-control systems. ELECTROFLO METERS CO., Ltd. Aug. 8, 1947, No. 21828. Convention date, Aug. 5, 1943. [Class 135] A gauge for indicating the level of liquid in a tank comprises a tube 10 which is inserted in the tank so that a bellows 17 at the bottom of the tube is subject through apertures 15 to the pressure due to the column of liquid in the tank, and the bellows actuates a device for producing a positive or negative pressure which acts on a diaphragm 22 connected to the bellows so as to balance the pressure acting on the latter, and this regenerated pressure is indicated on a vacuum or pressure gauge connected at 29. Bellows 17 is connected to a tube 21 and the upper end of the latter is connected to a lever 26 the free end of which obturates a nozzle through which air at atmospheric pressure entering past a filter 24 can flow into an enclosure 23. A vacuum source connected at 14 draws air from the enclosure past a restriction 28. The controlled pressure obtained in the enclosure 23 also acts on the diaphragm 22 carried by tube 21 and serves to neutralize the action of bellows 17 on the lever 26. Bellows 17 communicates through tube 21 with a further bellows 18 subject through apertures 16 to the pressure above the liquid in the tank so that the resultant force acting on lever 26 will be due solely to the height of the liquid column in the tank. A tube 13 communicating with the interior of bellows 18 runs parallel to tube 29 as far as the pressure gauge, whereby any difference of atmospheric pressure at the gauge and in the tank is neutralized. In a modification employing a positive pressure control fluid, the gauge is connected to the interior of bellows 18 in which the controlled pressure is obtained.
