Abstract: 910,896. Ventilating vehicles. DOWTY ROTOL Ltd. May 2, 1961 [May 10, 1960], No. 16492/60. Class 137. [Also in Group XIII] In a vehicle propelled by a diesel engine 11, a valve 19 allows some or all of the air to be tapped from the exhaust 17 of engine supercharger 13 to serve as the working fluid in a refrigerating system for the passenger compartment 12. As shown, the air passes in series through heat exchanger 21 (heating air in duct 22), expansion turbine 26, and exchanger 30 (cooling air in duct 31). Heating or cooling of the compartment 12 is determined by the positions of flap valves 24, 33 adapted to connect the ducts 22, 31 to the compartment or to ambient. The amount of conditioning air is determined by the position of butterfly valves 23, 32 at the duct inlets. Valve 19 may be automatically controlled. The exhaust air from the supercharger may be cooled upstream of valve 19. Turbine 26 may drive an alternator 28 or an additional engine supercharger.

Title: Oxo alcohol recovery
IPC: C07C29/16
Filed: 1950-07-04
Abstract: Oxo alcohols are separated from higher boiling impurities by liquid-liquid extraction with an aqueous solution of at least 25, preferably 35-40 per cent by weight, of a water-soluble salt of an organic sulphonic acid, preferably an alkali metal salt of an aromatic sulphonic acid, such as sulphonates of benzene or alkyl benzenes, the alkyl groups having 1-5 carbon atoms.  Aliphatic sulphonates are also suitable.  Sodium benzene, toluene, p-cymene, mixed xylene and n-butyl sulphonates are most suitable. Potassium, lithium, ammonium or amine salts, and salts of naphthalene, dimethylaniline, naphthol, naphthylamine, nitrobenzene, cyclohexane, lauryl, methane, ethane, and anthraquinone sulphonic acids are also specified.  The bottoms after distilling off Oxo alcohols is treated with the sulphonate solution, the aqueous phase separated, and the alcohol recovered, preferably by steam stripping.  Alcohols of C4-C15 may be treated.  Increasing the ratio of solvent to alcohol gives increased recovery.  In examples, crude iso-octyl alcohol or bottoms after distillation is extracted with solutions of sodium xylene sulphonates or sodium n-butyl sulphonate in ratios from 1 : 1 to 25 : 1, and of concentrations between 35 and 46 per cent, in one or more stages.

Screen 30 remains fixed to the casing by flange 31, and disc 342 forms a sliding seal, with a small gap, with the top edge of the screen, separating accepts space 19i from inlet space and deaeration space 19a and 18. Figs. 4, 5 (not shown) illustrate a screen 30 which is closed at the top by alternative outer and inner, annular covers (30a, 30i), depending on whether blades 43 are secured to their mounting ring 242a at the inner or outer diameter. Figs. 1, 2 (not shown) illustrate replacement of a wide diameter screen by a narrower one, retaining the same cleaning blades and their supporting spider. Fig. 3 (not shown) illustrates replacement of the supporting spider of Fig. 1 by one of larger diameter, while retaining the original screen. All the embodiments illustrated are designed for inward flow, with blades 43 inclined to generate reverse flow pulses as they sweep across the screen. However, a similar construction could be adapted to outward flow screening.
