Title: A process of treating coal
IPC: C10B55/00
Filed: 1931-05-04
Abstract: Carbonaceous substances, e.g. high-volatile coals, lignite, or peat are heated to change their coking qualities with a solvent preferably such as coal tar, water gas tar, and tar oils, though petroleum oils are not excluded, to a temperature, preferably above 400 DEG  C., at which the coal decomposes, the temperature being lowered before it is completely decomposed.  Solutions of the coal prepared as described in Specification 268,372, [Class 91, Oils &c.], are preferably employed and heated in an autoclave, this condition also facilitating the removal of ash and pyrites, the incorporation of fillers or catalysts, or chemical treatment as with dehydrogenating agents such as sulphur or oxygen.  In an example 100 parts of poorly coking high-volatile coal are heated in a rotating autoclave with 200 parts of anthracene to 400-430 DEG  C. for an hour.  The combined product may be used in paints or fuels.  A semi-coke of colloidal nature may be obtained by entirely devolatilizing the coal.ALSO:Carbonaceous substances, e.g. high-volatile coals, lignite, or peat, are heated to change their coking qualities with a solvent preferably such as coal tar, water gas tar, and tar oils, though petroleum oils are not excluded to a temperature, preferably above 400 DEG  C. at which the coal decomposes, the temperature being lowered before it is completely decomposed.

Title: Lactones of 2-methyl-3-hydroxy (and alkoxy)-4-carboxy-5-hydroxymethyl-pyridine
IPC: C07D491/048
Filed: 1945-05-25
Abstract: The lactone of 2 - methyl - 3 - hydroxy - 4 - car - boxy-5-hydroxymethyl-pyridine is obtained by treating a mineral acid salt of 2-methyl-3-hydroxy - 4 : 5 - dihydroxymethyl - pyridine with an aqueous solution of potassium permanganate. The lactone may be subsequently alkylated in the 3-position. Specified mineral acids are hydrobromic and sulphuric acids.  In an example, 2-methyl-3-hydroxy-4 : 5-dihydroxy-methyl-pyridine hydrochloride is treated with saturated aqueous potassium permanganate and the solution filtered, evaporated to dryness, and the residue extracted with ethanol.  The extract, acidified with hydrochloric acid, precipitates the lactone of 2-methyl-3-hydroxy-4-carboxy-5-hydroxymethyl-pyridine hydrochloride which on treatment with sodium bicarbonate solution yields the free base which is treated with diazomethane to give the corresponding 3-methoxy compound.

The apparatus may be used as an air precleaner for an air intake system for an I.C. engine. The outlet passage 119 is defined by a sleeve 118 in the lower portion of which is snugly fitted on interchangeable adaptor collar 121 which in turn snugly fits over a suction intake pipe 111 which may be mounted on, and project through, a vehicle structure and be connected to tubular means leading to the air cleaner of the engine. The sleeve 118 is joined by vanes 126 of the vane assembly to a tubular member 123 which is secured by screws 124 to the side wall 126. The latter has an outwardly extending portion 130 defining an outlet channel leading to the discharge opening 129 which is tangentially directed relative to the side wall, Fig. 3 (not shown). A peripheral lip 154 may be provided at the upper end of the tubular member 123 and extends inwardly towards the chamber a short distance to prevent interference between the air flow coming through the vane assembly 122 and air currents generated by the paddles 152 of the rotor assembly. The rotor assembly may be driven by a propeller disc 142 mounted on the lower end of the rotor shaft 134 and rotatable in response to the air flow through the outlet passage 119. In a modification, Fig. 5, the paddles 174 of the rotor assembly 164 are located in a channel 176 defined by an annular, outwardly enlarged ridge portion 175 of the housing 161 which is provided with a discharge opening 178. The rotor assembly is driven by the swirling air in the chamber 162 impinging in the paddles 174.
