Filed: 1975-09-18
Abstract: 1485347 Air over hydraulic braking; valves CATERPILLAR TRACTOR CO 18 Sept 1975 [31 Jan 1975] 38376/75 Headings F2F and F2V A valve 10 comprises valve spool 24 slidably mounted in a bore of a housing block 55 which also incorporates passageways 59, 29 and 39 communicating with the chamber 17 of a spring applied, hydraulically released emergency brake, a drain sump and a pump 41 respectively. In the position shown the brake fluid is allowed to drain from passage 59 to passage 29, past a spool portion 27 of reduced diameter, so that spring 16 applies the emergency brake. In operation however a chamber 36 is pressurized from reservoir 11 via emergency control valve 33 and parking valve 34 resulting in diaphragm 38 pushing rod 56, contiguous with spool 24, to the right as shown in the Figure such that land 53 blocks passage 59 from the drain and communication is opened between inlet passage 39 and passage 59 to release the brake. The pressure in passage 59 is communicated to a chamber 43 housing the spring 26 via passages 52 and 42 inside the spool 24 to act together with spring 26 on the spool 24 in opposition to the pressure in chamber 36. Thus when the pressure in chamber 43 has increased sufficiently to overcome the force exerted by the air in chamber 36 the spool will move back to the left to allow the brake cylinder to drain and the cycle of operation may start again depending on the pressure in chamber 36.

Title: Process for the purification of polyolefines having high molecular weight
Inventor: ANASTASIU STELIAN
IPC: C08F6/02
Filed: 1961-11-04
Abstract: A process for the purification of high molecular weight polyolefines obtained by polymerization using a catalyst comprising an organo-metallic compound and a transition metal compound characterized in that after the decomposition of the catalyst complex with alcohols, the removal of the impurities from the polymers takes place by washing out with aqueous solutions of ionic surface-active agents in the presence of non-polar or weakly polar solvents, followed by separation of the polyolefines from the washing medium, then a washing out of the polyolefines with water until disappearance of the surface-active agents from the washing water and finally, if desired, an extraction with non-polar or weakly polar solvents of any remaining polyvalent salt solutions of the surface-active agent.  The surface-active agents may be anionic and preferably water-soluble or soluble in a polar solvent, e.g. alkali soaps, alkylsulphates, alkylsulphonates, and alkylarylsulphonates or cationic agents with detergent characteristics, e.g. trimethyl-lauryl-ammonium chloride, may be used.  Suitable non-polar or weakly polar solvents for the optional last stage of the process are hydrocarbon fractions, e.g. benzine and any other solvent in which the polyolefines do not dissolve and practically do not gel and from which the polymer can be easily separated and which at the same time easily dissolve the polyvalent salt solutions of the surface-active agent.  In the examples, polyethylene and polypropylene are purified.
