Title: Improvements in and relating to the preparation of tablets of coffee or mixtures containing coffee
IPC: A23F5/12
Filed: 1933-06-27
Abstract: In a process for the preparation of tablets of coffee or mixtures containing coffee, the roasting of the coffee may be carried out in an atmosphere of an inert gas or gases or while substantially excluding oxygen, in order to retain the flavour of the coffee by preventing oxidization and reducing liberation of occluded gases. Carbon dioxide, nitrogen, hydrogen or argon may be used, or a mixture of carbon dioxide and monoxide, which may be wholly or partially supplied by the gases driven off during the roasting.ALSO:In a process for the preparation of tablets of coffee or mixtures containing coffee, the moulding and pressing of the ground coffee or mixture into tablet form may be carried out in an atmosphere of inert gas or while substantially excluding oxygen, in order to retain the flavour of the coffee by preventing oxidization and reducing liberation of occluded gas.  Carbon dioxide, nitrogen, hydrogen or argon may be used, or a mixture of carbon dioxide and monoxide, which may be wholly or partially supplied by the gases driven off during the roasting of the coffee.  The press should allow gases to escape from the tablets being pressed, to prevent the formation of laminations, causing liability to breakage.ALSO:In a process for the preparation of tablets of coffee or mixtures containing coffee, the ground coffee or mixture is pressed into tablets in an atmosphere of inert gas or gases or while substantially excluding oxygen, in order to retain the flavour of the coffee by preventing oxidization and reducing liberation of occluded gases; the packing or wrapping and the blending, roasting and grinding are preferably also carried out in a similar atmosphere.  The gas may be, for example, carbon dioxide, nitrogen, hydrogen, or argon, or a mixture of carbon dioxide and monoxide, which may be wholly or partially supplied by the gases driven off in roasting the beans.  Chicory, wheat, oats, rye or figs may be mixed with the ground coffee before pressing into tablets. The press should allow gases to escape from the tablets being pressed, to prevent the formation of laminations, causing liability to breakage.  The tablets may be stored in an inert gas in metal or like containers, preferably hermetically sealed, or they may be sealed in wrappers in a similar atmosphere. The wrapping may be of viscose or acetate material lacquered to render it gas-tight. Cartons for packing the tablets may be formed of material having a layer of bitumen or the like between two cardboard or fibre layers. The processes may be carried out in a circulating closed circuit of inert gas, in which the steam given off in roasting is condensed before grinding; the gas preferably passes upwards through the grinder, since the gas released in this process tends to rise.

Title: Improvements in and relating to the separation of materials of different densities by means of a dense suspension
IPC: B03B5/44
Filed: 1946-06-20
Abstract: 626,861. Washing granular materials. BOLIDENS GRUVAKTIEBOLAG. June 20, 1946, No. 18604. Convention date, June 21, 1945. [Class 82(ii)] In a process for separating materials of different densities by means of a dense suspension in a separating device 101 and in which the heavy medium for the suspension is supplied by the material itself, the dense suspension is taken from a closed circuit grinding system containing one or several other separating devices 105, wherein is formed the fine particle fraction of the material from the first separating device 101, which has not been in effect separated, and possibly also the coarse fraction of higher density which has not been freed in the first separating device from lower density material. Raw material is fed to the device 101 containing a dense suspension, from which the lighter and fine particle fraction is led through the line 111 to washing screens 113, 114, the washer gangue being rejected at 115 whilst the screened suspension and fines are led via line 121 to the closed grinding circuit comprising a grinding mill 103 and size-classifier or classifiers 105. Wash water from the screen 114 may also be admitted to the grinding circuit via line 141. The heavy fraction (values) from the separator 101 is removed at 123a by a rake, but in general some or all of such heavy fraction is led via line 123 to the grinding mill 103 where it is ground or mixed with the fines and wash water to form heavy suspension which is led to the classifier 101 via the line 131. Particles removed at 129 from the size-classifier 105 may be subjected to further recovery treatment if desired. In a modification, Fig. 2, (not shown), the closed grinding circuit includes in addition a classifier 251 similar to the primary classifier 101, the dense suspension being led to the classifier 101 from a point below the surface of the liquid in the classifier 251 via the line 231.

Title: Improvements in or relating to apparatus for measuring or responsive to the level of a liquid
Inventor: MARTIN ROBERT EDGAR
IPC: G01F23/24
Filed: 1969-04-11
Abstract: 1,257,737. Level indicating. CENTRAL ELECTRICITY GENERATING BOARD, R. E. MARTIN and E. F. HASLER. 26 June, 1970 [11 April, 1969], No. 18693/69. Heading G4H. The water level in a boiler is detected by four level detectors 11, 12, 13 and 14; faults in the apparatus are detected by comparing the outputs of the detectors. Detectors A and B detect the water level at the same point, are compared at 25 and any difference causes an alarm 26 to be sounded. Detectors C and D operate in a similar manner. Detectors A and C are compared at 30 and detectors B and D are compared at 33, the differences recorded between these pairs of detectors are used to control the operation of the boiler by means of controlled circuitry 32. If a fault is detected then the alarm 26 sends an inhibit signal to the control circuitry 32 to prevent the operation of the control circuit on the basis of incorrect input data. The comparison between detectors A and C, Fig. 3, is performed in both an analogue and a digital manner. The output of the detectors 42 and 46, which each comprise a series of electrodes at different levels which are shorted out by the water level, are fed to a digital to analogue converter 50 and a digital to analogue converter 51. The outputs of the individual detectors are recorded on meters 52 and 53, and any difference between the two level detectors is recorded on central zero meter 54. A digital output which may be used to actuate an alarm is provided by means of relay contacts 71 to 82 which are connected alternately to level detectors 42 and 46. In correct operation the conductors 83 and 84 should be isolated from one another, however if a difference in the levels recorded by the two detectors exists then one pair of contacts at least will be connected in such a way as to short across the two conductors 83, 84. The output of the logic units 61, 62 may be fed to displays 90, 91 and 92 to indicate the liquid level. These displays also act as fault indicators. U.K. Specification 1,056,032 is referred to.

Title: Method of regenerating spent liquors produced in the pickling of iron or steel products
Inventor: KRAMARSIC VINKO
IPC: C01B17/90
Filed: 1958-06-13
Abstract: Spent pickling liquors are regenerated and the iron values are recovered by cooling to -12 DEG  to -16 DEG  C., thereby crystallizing ferrous sulphate heptahydrate, which is separated.  The ferrous sulphate may then be redissolved in water and precipitated with caustic alkali to produce iron oxide or hydroxide, which is separated, and a sodium sulphate solution.  The latter is enriched with solid sodium sulphate produced in a subsequent stage and is then electrolised to produce caustic soda and a sulphuric acid solution of sodium sulphate.  The caustic soda solution is recycled to the iron oxide precipitation step.  The acidified sodium sulphate solution is cooled to -8 DEG  C., thereby precipitating sodium sulphate, which is separated and recycled to enrich the sodium sulphate solution passing to electrolysis.  The sulphuric acid solution remaining is combined with the initial regenerated pickling liquor from which the ferrous sulphate has been separated, and the mixed liquor is cooled to -15 DEG  to -20 DEG  C., whereupon 25 to 30% of the water content is removed as ice crystals, which are employed to cool the spent initial pickle liquor, or to dissolve the ferrous sulphate before precipitation with caustic soda.  The final solution contains 20 parts by weight of sulphuric acid and may be employed for further pickling.
