Title: Preservation method for foods in the home: preserving, storing and removing the foods, and the entire apparatus for carrying out this process
Inventor: DROSDOL BRUNO
IPC: A23L3/10
Filed: 1986-03-29
Abstract: A preservation process on a domestic scale for foods (fruit, vegetables and the like), which does not harm the vitamins and is relatively cheap, simple and easy to use. The material to be cooked is heated in a cooking pot for a short time and at a temperature only high enough so that the bacteria, moulds and the like are killed but the vitamins are still well retained. The material is then packed hot into prepared jars, these are covered with a novel jar lid having a central venting hole and having a bead on the lid ridge and are very highly evacuated (down to 2.5% residual air) by means of an ejector. Familiar flat rubber rings can be laid between the jar rim and jar lid. Seal rings made of round rubber are recommended, more suitable for jars having a sealing groove. The vent hole is covered with a flat seal ring and a closure lid with the aid of a novel suction cap during evacuation and in the closure operation. The cooked material in the jars can be stored in a known manner for months in a dark, cold cellar (below 18 DEG C). Opening the jars is facilitated by two special levers, even in the case of jars having sealing grooves. Using a lever with a steel point which fits into a lateral blind hole of the closure lid, this is vented; air hisses into the jar and the jar lid is free. If however it is "stuck", the three knobs of the second lever are pushed under the jar lid to vent ... Original abstract incomplete.

Title: Combined catalytic two-stage processing of coal/oil charges
Inventor: MACARTHUR JAMES B
IPC: C10G1/06
Filed: 1986-04-21
Abstract: The invention relates to a process for the two-stage catalytic combined processing of coal and heavy crude oil fractions for the production of increased yields of low-boiling hydrocarbon liquid and gas products. In the process, the particulate coal is slurried with a crude oil residue and, if appropriate, with a liquid solvent obtained from the process and is fed to a catalytic reaction zone of a first stage, which is operated under relatively mild conditions which promote a controlled liquefaction rate of the coal, while at the same time the crude oil and the recycled hydrocarbon oils are hydrogenated under conditions which favour hydrogenation reactions. The reactor of the first stage is held at a temperature of 343 to 427 DEG C (650 to 800 DEG F), at a hydrogen partial pressure of 105 to 246 kg/cm<2> (1500 to 3500 psig) and 4.54 to 45.4 kg/hour/ft<3> space velocity for the total coal and oil charge. The partially hydrogenated material from the reaction zone of the first stage is taken directly to the catalytic reaction zone of the second stage, which is held under more severe conditions at a temperature of 399 to 482 DEG C (750 to 900 DEG F) for the further hydrogenation and catalytic hydroconversion reactions. By means of this process, the mixed coal and crude oil feedstocks are successively catalytically hydrogenated and hydroconverted under select conditions... Original abstract incomplete.
