Abstract: 1,008,086. Reciprocating pumps and compressors. DE LAVAL TURBINE Inc. Aug. 3, 1962, No. 30065/62. Headings F1A and F1N. In a liquid pressure-actuated diaphragm pump, e.g. for radio-active liquids with suspended solids, or gases, comprising a driving diaphragm or bellows 156, Fig. 3, and a pumping diaphragm or bellows 186, both of stiff material, e.g. metal, and connected by a liquid column 172, the return movement of driving diaphragm 156 is effected by the static pressure of the liquid column in a stand pipe 164. Part of the column comprises a heavy liquid 168, e.g. mercury, and the rest, a lighter liquid 170, e.g. water. In the embodiment shown, two pumps each with tenden inlet and outlet valves are arranged in parallel and their driving diaphragms 156 are actuated alternatively by pressure liquid, e.g. oil, supplied by a pump 23 and distributed by a slide valve 28, Fig. 2. Valve 28 is reciprocated by a motor 2, Fig. 1, acting through a crank 10 and slide 16. When valve 28 is in its left-hand position shown, one diaphragm 156 receives pressure liquid via ports 40, 46, 42, 78, ball valve 74 and conduit 98, whilst the other diaphragm 156 exhausts via conduit 96, ports 52, 56, 60 and conduit 69. Reversal of valve 28 results in supply of pressure liquid via ball valve 76 to conduit 96 and exhaust of pressure liquid from conduit 98 to conduit 67. The output of the diaphragm pumps may be varied by varying the output of pump 23 and the rate of reciprocation of valve 28. A heat exchanger 174 is provided on conduit 172.

In a hatch cover swingable about hinges 5 located outside the hatch opening and operated by a pressure medium actuated jack 9, the jack is pivotally secured at 13 to the cover and at 11 to a portion of the deck parallal to the hinge axis of the cover at such a location that with the cover in its fully upwardly swung position the jack will lie outside the hatch opening so as not to prevent the handling of the load or be likely to be damaged thereby. The pivot 11 is arranged in a recess 12 of the coaming. The cover is in two sections 2, 3 hinged together at 4, the outer section 2 having wheels 6 running on a track 7 at the coaming 1, the track terminating in a curved gradient 8 to enable the sections to commence a closing movement from their raised position as soon as the restraining force is removed. When the jack is supplied with pressure medium the cover sections are swung upwards to take the position shown by dash lines in Fig. 1, in which position the parts of the jack projecting above the coaming recess are enclosed between, and protected against damage by, the cover sections.

Title: Process for the production of new derivatives of barbituric acid
Filed: 1935-11-01
Abstract: 5 : 5-Disubstituted barbituric acids and their N-substitution products, in which one of the 5-substituents is the furfuryl group and the other is an isopropyl, allyl or isobutyl group, are prepared by condensing the corresponding malonic acids with urea or its derivatives, followed if necessary by hydrolysis, or by introducing one or both of the radicles into the barbituric acid by treatment with the appropriate halide.  The products are useful as hypnotics. Examples describe the preparation of (1) 5-furfuryl-5-isopropyl-barbituric acid by heating 5-isopropylbarbituric acid in caustic soda solution with furfuryl chloride; also by condensing isopropyl - furfuryl - malonic acid diethyl ester with urea in presence of sodium alcoholate; (2) 5-furfuryl-5-isobutyl-barbituric acid by reacting 5-isobutylbarbituric acid with furfuryl bromide in presence of copper sulphate; (3) 5 : 5-allylfurfuryl-barbituric acid from 5-furfurylbarbituric acid and allyl bromide in presence of copper sulphate; (4) 5-furfuryl-5-isopropyl-1-methyl-barbituric acid by condensing isopropyl-furfuryl-malonic acid diethyl ester with N-methylurea in methanol solution.  Isopropyl-furfuryl-malonic acid diethyl ester is obtained by treating sodium isopropylmalonic acid diethyl ester with furfuryl bromide.
