Title: Selective combustion process for hydrogen-containing comustibles  and apparatus therefor
IPC: G01N27/62
Filed: 1970-10-06
Abstract: 1320954 Analyzing gases electrically ESSO RESEARCH & ENG CO 6 Oct 1970 [20 Oct 1969] 47459/70 Heading G1N In apparatus for measuring low concentrations of hydrogen-containing combustibles, including methane, in a gas stream, the gas stream is passed through a combustion chamber containing an electrical heating element of a noble metal having a variable voltage supply controlled by a timer to provide a predetermined temperative cycle in the combustion chamber so that all of the, or selected, hydrogen-containing combustibles are oxidized, the treated gas stream passing to a flame ionization detector which measures the hydrocarbon content, or to a coated Piezo-electric crystal detector which measures the water produced by combustion of the hydrogen-containing combustibles at each stage of the cycle. The combustion chamber is a quartz tube and the heating element is of platinum, palladium, or a platinum or palladium alloy. Where a Piezoelectric crystal detector is used the gas stream is dried before reaching the combustion chamber. The detector measurements are plotted on a penrecorder, the resulting traces indicating the amounts of methane, other hydrocarbon, and hydrogen in the gas stream, Figs. 6, 7 (not shown). The coated Piezo-electric crystal detector may be as described in Specification 1061767 and 1255091.

Abstract: 1490370 Preparation of tea extracts SOC DES PRODUITS NESTLE SA 4 Nov 1974 [5 Dec 1973] 47564/74 Heading A4E [Also in Division A1-3] A process for preparing a tea extract comprises confining an aqueous tea slurry at a temperature of at least 90C in a first zone for a period of at least 2 minutes while confining a body of aqueous extraction liquid at a temperature of at least 90C in a second zone and in contact with a liquidpermeable barrier separating the first and second zones to permit diffusion of tea solubles from the aqueous tea slurry into the aqueous extraction liquid, the volume of the slurry being 0À5 to 2À5 times the volume of the aqueous extraction liquid, then removing aqueous slurry and extraction liquid from the respective first and second zones, and combining at least a part of the tea-solubles diffused into the extraction liquid with tea-solubles remaining in the aqueous slurry. An apparatus for preparing such tea extracts comprises a vertical column 1 having a perforated wall 2 surrounded by a jacket 3. Dry tea is supplied through 11 and hopper 4, and aqueous medium is supplied through line 10 to the hopper. Extraction liquid is supplied through line 12 to jacket 3. The column 1 is supplied with scraper blades 6 mounted on arms 7 and driven by means of shaft 8 to prevent blockage of the openings in wall 2. Tea slurry is withdrawn from cone 5 via line 13, valve 15 and pump 17; extraction liquid is withdrawn from jacket 3 via line 14, valve 16 and pump 18. The apparatus is suitable for batch-or continuous-production. In a preferred continuous process, the extraction liquid is water and the aqueous medium for the slurry is hot water. After withdrawal from the described apparatus the slurry and extraction liquid are combined and the leaves are separated, the extract is concentrated and dried to produced the dry powder extract. The spent leaves are washed and treated with steam to strip the aromatics which are added to the concentrated extracts. The wash-liqueur forms a secondary extract which is combined with the main extract before concentration, or may be partly used as the extraction liquid or the aqueous slurry medium. The slurry and extraction liquid may additionally be stripped of aromatics, either separately or combined prior to the leaf separation stage, the aromatics being combined with those produced from the spent leaves.

Air is fed to the exhaust manifolds through pipes 26, 28, in amounts which decrease as engine speed increases. The air is delivered by an impeller type pump 30 and is controlled by a spool type valve 34 actuated by a fluid type governor 16 driven at engine speed from the transmission 12. At low speeds the valve permits the air entering at 32 to flow through an opening 102 in the valve land 92 to pipe 36 leading to the exhaust manifold. At a predetermined speed the fluid pressure in pipe 18 acts upon land 94 to move valve spool 96 to the left to close passage 36 and divert the air flow to passage 38 leading to atmosphere or to the air pump inlet. The pump comprises a rotor 54 mounted on bearings 50, 53, and sealed to the stator 56 by sealing rings 70, 72, the air entering at 58 and leaving at 60.
