Abstract: 1,062,972. Electron microscopy. TECHNICON CO. Inc. June 4, 1964 [July 12, 1963], No. 23176/64. Heading H1D. [Also in Division G2] Histologic tissue is prepared for electron microscopic examination by automatic immersion of the specimen in a series of liquids in containers, the specimen being moved from one container to the next at predetermined intervals, wherein the time spent by the specimen in each container is the same, and the requirement that the time of action of each reagent is different for each reagent is met by providing a plurality of containers of the same reagent, such that the specimen moves from one container to another of the same reagent. After the above treatment, the specimen may be immediately placed in a thermosetting liquid embedding material, which is thereupon heated to set it. Preferably at least two heating zones are employed, the temperature in the latter zone being higher than in the earlier zone. For example a container with the tissue in the embedding material may be passed through a tunnel on a conveyer belt, the tunnel being provided with heating elements and movable transverse walls to divide the tunnel into a plurality of zones.

Patent GB-634471-A (GB)
Title: New pyrimidine derivatives
Filed: 1947-08-22
Abstract: Aminopyrimidinium quaternary salts (or tantomeric iminodihydropyrimidine salts) are manufactured by treating a 2-, 4- (or 6-) aminopyrimidine, which is substituted in another of the 2, 4- (or 6-) positions by a halogen atom or a group -SR (R being a hydrocarbon radical) and may be substituted in the remaining 2-, 4- (or 6-) position by an alkyl radical of not more than 5 carbon atoms or amino group, with a quaternary salt forming agent, e.g. a compound of the formula Alkyl A (where A is an anion such as halogen, -SO4CH3 or -SO3C6H4CH3).  The reaction may be effected by heating the reactants together, conveniently in the presence of a solvent, e.g. b -ethoxyethanol, ethanol, nitrobenzene, nitroethane or ethyl acetate. When the substituents are unsymmetrically placed in the starting material, two possible quaternary salts are obtainable, and the product generally consists of a mixture thereof, though usually with one in predominating amounts.  When the quaternating agent is an alkyl halide of which the halogen is different from that in the pyrimidine compound, a complete or partial interchange thereof may occur, and this may affect one isomer more than the other in cases where two products are possible.  Thus the action of methyl iodide on 4-chloro-2-amino-6 - methylpyrimidine yields 4 - chloro - 2-amino - 6 - methylpyrimidine 1 - methiodide (or 4 - chloro - 2 - imino - 1 : 6 - dimethyl-1 : 2 - dihydropyrimidine hydriodide) and 4-iodo - 2 - amino - 6 - methylpyrimidine 3-methiodide (or 4 - iodo - 2 - imino - 3 : 6-dimethyl - 2 : 3 - dihydropyrimidine hydriodide).  Examples describe the treatment of (1)-(4) 4-chloro-2-amino-6-methyl- and 4-chloro- and 4 - iodo - 2 : 6 - diamino - pyrimidine with methyl iodide; (5) and (13) and (6) 4 - chloro - 2 - amino - 6 - methylpyrimidine with dimethyl sulphate and methyl p-toluene-sulphonate; (7)-(12) 2-chloro- and 2-methylthio - 4 - amino - 6 - methyl -, 4 - chloro - 6-amino - 2 - methyl-, 4 - amino - 2 - methylthio-and 2 - amino - 4 - methylthio - 6 - methyl - pyrimidine with methyl iodide. Diethyl sulphate is also specified as a quaternating agent.
