Title: Improvements in or relating to the removal of paraffin from mineral oils
IPC: C10G73/06
Filed: 1921-10-03
Abstract: Paraffin wax is removed from crude oil by treating the crude oil, or centrifuging or otherwise treating the oil remaining after distillating it to 160 DEG  C., with alcohol, oil of turpentine, or both, in the cold and filtering or centrifuging.  The impure wax may be used as briquettes, or may be distilled in vacuo, neutral bituminous matter of high melting point remaining in the still, and hard paraffin distilling over.  This wax may be further purified by centrifuging or by sulphuric acid or other known chemical process to yield white wax having a melting point of or about 69 DEG  C.

Abstract: 601,759. Forming crystal lenses by solvent action. FARNSWORH TELEVISION & RADIO CORPORATION. Oct. 11, 1945, No. 26549. Convention date, Nov. 11, 1944. [Class 124] In a method of forming a lens from a blank of soluble material, a film of solvent is formed on a mould which is the negative of the lens form and is then transferred to those portions of the blank which do not conform to the configuration of the mould, the mould and blank being periodically separated and the solvent removed from both surfaces. As shown, a crystalline blank 14 of sodium chloride mounted on a reciprocating shaft 17 having a lost motion device 24 is brought into contact periodically with a mould 5 which has a film of water deposited on it from a nozzle 11. The solvent is transferred to the high points of the blank from which a thin film is dissolved. Both surfaces are cleaned, after separation, by a blast of air from nozzles 40 and 41 controlled by a cam 50 and a valve 45. The mould may be cooled in order to ensure that the solvent is condensed to a thin film on its surface.

Abstract: 688,782. Mine roof support bars. ALLAIN, P. L. Nov. 9, 1950. No. 27412/50. Class 20(ii) Mine roof support bars 1A, 1B, Fig. 1, are connected end-to-end by means of male and female end portions 2, 3, the male end 2 having an arcuate upper surface 7 engaging a similarly formed top wall 10 of the female end 3 which has an open bottom and side walls 12 formed with slideways 13 for the side wings 16 of a wedge 15 adapted to bear against the under surface 9 of the male end 2. In assembling the roof support bars the rear end of the bar 1B is raised to insert the male end 2 through the open bottom of the female end 3 of the prop-supported bar 1A and to rest it on a nose 11, the forward end of the bar 1B being then raised and the wedge 15 inserted to hold the bar 1B as a cantilever. A further prop is then inserted under the male end of the bar 1B and flexibility imparted to the connection by removal of the wedge. On removal of the prop supporting the rearmost bar, the latter swings downwardly about the arcuate surface 7 of the adjacent bar and the angular extent of the surface is such that the female end is disengaged from the male end before the rearmost bar has touched ground. This facilitates the recovery of bars in seams of small thickness. As shown in Fig. 1, the arcuate surfaces 7, 10 are cylindrical about a transverse axis but in a modification shown in Fig. 7, the co-acting surfaces 7, 10 cf the male and female ends are bi-conical, the former having a cut-out portion 23 adapted to straddle a web 4 in the female end which is provided with a platform 24 for supporting the tip 22 of the male end during erection of the associated bar.
