Title: Improvements in or relating to citrus fruit solid concentrates
Inventor: SPROSS SPENCER ASA
IPC: A23L2/08
Filed: 1960-03-14
Abstract: Citrus fruit solid concentrates are prepared by extracting the juice from citrus fruits, removing excess pulp from the juice, extracting from the remaining juice both soluble and insoluble fruit solids (e.g. by cold water to give a juice having 8-12% soluble solids and 10-25% insoluble solids), removing the larger insoluble fruit solids from the juice, heat stabilizing the juice to sterilize it and to inactivate naturally occurring pectin enzymes in the juice solids, treating the juice with enzymes to effect flocculation of the remaining insoluble fruit solids, hydrolization of the pectin and debittering of the juice, separating out the flocculated insoluble fruit solids, and then concentrating the resulting juice.  The heat stabilizing is carried out by heating the juice from which the larger insoluble fruit solids have been removed to a temperature of 205  DEG F. for six seconds.  In the enzyme treatment, enzymes such as pectin esterases and carbohydrase (pectinase, diastase and cellulase) are added to the juice in amounts from 0.25 g to 10.0 g per gallon of juice with the juice at a temperature of from 100 to 150  DEG F. The concentration is conducted in a vacuum of 29.5 to 29.8 inches to give a concentrate substantially free from insoluble fruit solids and having a density in the range of from 70  DEG  to 80  DEG  Brix at 70 DEG F.  The concentrate obtained is cooled to 20  DEG F. and then frozen for storage to zero degrees F. or below by an air blast in a freezing room.ALSO:Citrus fruit solid concentrates are prepared by extracting the juice from citrus fruits, removing excess pulp from the juice, extracting from the remaining juice both soluble and insoluble fruit solids (e.g. by cold water to give a juice having 8-12% soluble solids and 10-25% insoluble solids), removing the larger insoluble fruit solids from the juice, heat stabilizing the juice to sterilise it and to inactivate naturally occurring pectin enzymes in the juice solids, treating the juice with enzymes to effect flocculation of the remaining insoluble fruit solids, hydrolisation of the pectin and debittering of the juice, separating out the flocculated insoluble fruit solids, and then concentrating the resulting juice.

Title: Production of cis-cyclohexane-1, 2-dicarboxylic anhydride
IPC: C07C51/567
Filed: 1955-03-29
Abstract: Cis-cyclohexane-1,2-dicarboxylic anhydride is produced from cis-4-cyclohexene-1,2-dicarboxylic anhydride by reaction with hydrogen in the presence of a hydrogenation catalyst.  The process is characterized in that the cis-4-cyclohexene-1,2-di-carboxylic anhydride is reacted in a molten state in the absence of a diluent, whilst the reaction mixture is maintained at a temperature not exceeding 150 DEG  C.  The catalyst may be nickel, e.g. prepared by reduction to metallic nickel of a coating of nickel hydroxide or carbonate on a silica carrier.  The presence of alkali metal ions in the catalyst is avoided by washing the hydroxide or carbonate if alkali metal hydroxide or carbonate has been employed in the preparation or by the use of ammonium carbonate or hydroxide to effect precipitation.  The product is purified by fractional distillation.  The desired product may be obtained from light fractions by heating with water to convert the anhydride to the corresponding acid which is then crystallized from water and thermally dehydrated to the anhydride which is again fractionated. Examples, using a starting material obtained by reacting 1,3-butadiene with maleic anhydride, are furnished. The product may be heated under reduced pressure first to convert any cis-cyclohexane-1,2-dicarboxylic acid present to the anhydride and then to distil the product.  The product is suitable for producing epoxy resins.

Title: Process and devices for the transfer of a gas
IPC: F04B37/02
Filed: 1972-02-28
Abstract: 1388122 Obtaining high vacua by adsorption L'AIR LIQUIDE SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 28 Feb 1972 [26 Feb 1971 2 April 1971] 9134/72 Heading F1N A device for transferring gas from a chamber 22, via an adsorption compartment 1, to a further location through conduit 24, comprises pipes 9a, 9b, 9c inter-connecting tanks 7, 8 which are respectively connected to outlet and inlet conduits 12, 11, tapes 15a, 15b being interwoven around pipes 9a, 9b, 9c and being of an adsorbent material. Cryogenic liquid flows through the pipes 11, 12, 9a, 9b, 9c and tanks 7, 8 continuously throughout each gas transfer cycle. Tapes 15a, 15b are made of wire 14 into which are embedded particles 13 of an adsorbent substance. By putting a voltage across the ends of the wire via leads 17, 18 the adsorbent substance 13 can be heated since the heat generated is greater than the cooling power of the cryogenic liquid. This heat is only applied for a predetermined time during each cycle. Thus, with the cryogenic liquid acting through the pipes so that only a cooling effect is present the adsorbent substance 13 has its temperature lowered to an adsorption point, whereupon valve 23 is opened and gas from chamber 22 adsorbed into substance 13. Then valve 23 is closed and the wire 14 and substance 13 heated to a desorption temperature, thus overcoming the continuing cooling effect of the cryogenic liquid. The gas is thus desorbed from substance 13 and valve 25 opened to permit the desorbed gas to flow to another location. In a further embodiment Figs. 3 to 6, (not shown) the adsorbent substance is in the form of strips held between parallel plates and electrically series connected. Alternatively, the strip can be thickly wound round a central conduit for the cold liquid, Figs. 7, 8 (not shown). The device can also be used, usually in combination with similar devices, as a compression in a Joule-Thomson refrigerator system, Figs.9, 10, 11 (not shown).

Title: Train control apparatus
IPC: B60T15/04
Filed: 1923-01-23
Abstract: 219,622. Marks, E. C. B., (Clifford International Corporation). Jan. 23, 1923. Fluid-pressure.-Automatic application of the brakes of a train is effected by venting air from the train pipe through a valve operated by pressure air supplied through a trigger valve, preferably from the equalizing-reservoir of the driver's brake valve, the latter being cut off from the train pipe during the operation of the valve. The invention is described and shown as applied to a standard braking equipment. When a roller 1<x>, Fig. 1, engages a track ramp, a valve 9<x> is opened to supply air from the equalizing-reservoir x to the piston chamber a of a trigger valve, Fig. 3, whereby the piston b is moved to the right to operate a lever 18a and rotate a valve 19<a> to connect the pipes 13<x>, 15<x> by a passage 22<a>. Air from the reservoir x is thus supplied to a valve A, to move the piston 46, Fig. 2, to the right and operate the slide valve 41 to vent the train pipe T.L. through the port 44<1>. At the same time the slide valve 53 is moved to the right to supply air from the passage 55 to the pipe 51 and the member b<11> of the valve B, Fig. 4, is moved to the left to disconnect the driver's valve, connected at 50, from the train pipe, connected at 50a. The valve 19<a> is locked in open position by a latch 26<a> until air fed into the chamber 35<x> by a port 15<a> forces the piston 36<a> to the left to disengage the latch by a cam 27, when air supplied to the chamber a<1> by the pipe 37x returns the piston b and valve 19<a> to normal position. Air from the valve A now exhausts through the pipe 15<x> and port 22<11>, the return of the piston 46 and slide valves 41, 53 closing the exhaust port 44<1>, and allowing the pipe 51 to exhaust through the port 56, so that the valve B is also. returned to normal position. The communication between the reservoir x and the trigger valve may be controlled by a solenoid from a primary relay. When the system is used with a roadside ramp a valve B<1> may be used to close the pipe 15<x> and thus operate a valve H<6> to service position to cause a diminution of speed. Specification 217,946 is referred to.

Title: Manufacture of solutions of decomposition products of saccharides
IPC: C07C51/295
Filed: 1941-07-22
Abstract: The residual free alkali present in the lactate containing solutions obtained by decomposing saccharide solutions with alkali is reduced but not wholly consumed by reaction with more saccharide.  The amount of saccharide employed corresponds to at least 1 C6-unit for each 2 equivalents of alkali, but does not exceed the quantity required to leave unconsumed alkali. Alkali metal compounds having an alkaline reaction may be used as the alkali and the use of monosaccharides such as dextrose, laevulose or the hydrolysis products of carbohydrates and disaccharides or oligosaccharides such as lactose, sucrose or molasses is described.  In the examples inverted sucrose, lactose and dextrose are treated with sodium hydroxide and then with additional saccharide, yielding viscous solutions of low freezing point, which may be used for anti-freeze purposes.
