Title: A process for obtaining organic oxy-compounds
IPC: C07C29/00
Filed: 1938-07-25
Abstract: 506,473. Separating organic compounds. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. July 25, 1938, No. 22079. Convention date, Aug. 10, 1937. [Class 2 (iii)] Organic oxy-compounds such as alcohols, ethers and esters arc obtained from mixtures comprising two liquid phases encountered in the course of manufacturing such oxy-compounds, by separating the phases and extracting at least a part of the oxy-compound from the phase of more hydrophobic character, such as a hydrocarbon phase, by contacting it with a part of the other phase at a temperature below that prevailing during the pbase separation. The process may be used for the removal of free carboxylic acid, such as acetic acid, from the ester phase of a mixture consisting of an ester phase, such as an amyl acetate phase obtained from amylene and acetic acid, and an esterification catalyst phase, such as a sulphuric acid phase, or to obtain an alcohol from the hydrocarbon phase of an alcoholcontaining mixture consisting of an olefinecontaining hydrocarbon phase and an olefine hydration catalyst acid phase, such as an inorganic polybasic acid phase, or to obtain an alcohol from the ether phase of an alcoholcontaining mixture consisting of an ether phase and an etherification catalyst phase. The extractor used may be a tower for promoting counter-current contact or a mixing tank and the extraction may be carried out continuously, batchwise or intermittently. Typical esters which may be freed from the corresponding free carboxylic acid are the ethyl, propyl, butyl, amyl and allyl esters of formic, propionic, butyric, crotonic, benzoic, succinic and methacrylic acids or esters containing halogen or hydroxy substituents. The process may also be applied to the recovery of methyl alcohol in the production of methyl-tertiary amyl ethers from a tertiary amylene-pentane fraction and methyl alcohol.
Patent GB-1345994-A (GB)
Title: Starting mechanism
IPC: F02N15/06
Filed: 1972-05-11
Abstract: 1345994 Starter drives GENERAL MOTORS CORP 11 May 1972 [17 May 19711 22124/72 Heading F1K Upon commencement of rotation of a rotor 38 a plunger 32 is caused to move axially towards a pinion 18 through the inertial interaction between splines 42 and 43. Part of the torque available from the rotor 38 is imparted to the shaft 20 due to the preload exerted on the clutch by the spring 26 and the Bellville springs 22. However being slidably connected to the plunger 32 by splines 94 the driving clutch assembly 36 and the clutch backplate 102 do not move axially towards the pinion end until the flange 120 of the plunger 32 engages with and axially clutches the flange 122 of nut 34. Upon such clutch engagement translational movement of nut 34 is communicated via flanges 120 and 122 to the shaft 20 and the cup 54 thereby advancing the pinion 18 towards the starter on ring gear 14. Upon clearance of interference between the teeth of pinion 18 with those of gear 14 the spring 26 advances the pinion 18 into full engagement with the ring gear. Rotation of the ring gear 14 by the pinion 18 then commences with the clutch assembly 36 being held in an engaged position determined by the abutment of flange 120 of the plunger 32 with the snap ring 78. The resisting torque represented by the non-started engine results in the application of torque between the shaft 20 and the plunger housing 40 that causes splines 42 and 44 due to their different pitches to apply an axial rearward jacking force on nut 34 and a forward jacking force on the shaft 20. The effect of the jacking force is not to translatably move the nut 34 towards the rotor end 62 because such translational movement is prohibited by the abutment of flanges 120 and 122 but to cause a slight forward translational movement of the shaft 20 relative to the nut. This forward screwing of the shaft 20 in the nut 34 correspondingly moves Bellville springs 22 axially and thereby increases the normal axial force applied by the clutch backplate 102 to the driving and driven discs 90, 92.

Title: Improvements in or relating to machines for cleaning bottles
IPC: B08B9/36
Filed: 1951-09-21
Abstract: 697,270. Bottle-washing machines. SEITZWERKE GES. Sept. 21, 1951 [Sept. 21, 1950], No. 22126/51. Class 138 (i). In a bottle washing machine in which the bottles circulate intermittently in an upright inverted position from a loading point to an unloading point and are rotated by contact with internal and external rotating brushes, the bottles, before reaching the unloading point, are raised relative to the brushes and so held whilst continuing to rotate, and just before reaching the unloading point the water supply to the internal brushes is cut off, whereby a final rinsing effect is obtained whilst the bottles still rotate. Brush rods 11, Fig. 3, are located on an intermittently rotated table 10 at eight uniformly distributed positions as shown in Fig. 2. Each movement of the table corresponds to the space between two brush rods. A bottle 12 is slid over a rod 12 at position 1, Fig. 1, with the aid of a centering device comprising arms 13, 14. The rods 11 are supplied with water and ro-. tated to clean the interior of the bottle which is also rotated by frictional contact with the brushes on the rod. At positions 4 and 6 the bottoms of bottles are cleaned by the contact with brushes 15, 16. The brushes 15, 16 are fixed on arms 24, 25 on a shaft 17 pivotable by the movement of a lever 21 between the arms. A member 26 on the lever 21 is engageable in one of eight recesses in a control ring 20, Fig. 3, connected by brackets 18, 19 to the table 10 for movement therewith. As the table moves the member 26 rides out of the recess and causes the brushes 15 and 16 to lift away from the bases of the bottles. At position 7 the bottle is lifted, by mechanism (not shown), relative to the brush rods and is still rotating so that final rinsing is effected, water only running out of the bottle slowly due to the brushes obstructing the bottle neck. At the unloading position 8 the bottle is removed and the water supply automatically cut-off. The rotating water still in the bottle rushes out to flush the bottle. The table is driven from a motor 31, Fig. 3, which also drives through mechanism 35, 36 a brush roller 33, Fig. 2, for the external cleaning of the bottles.
