Title: Improvements in or relating to the manufacture of tea
IPC: A23F3/06
Filed: 1949-12-06
Abstract: 692,778. Tea manufacture. BAKE, A. M. H. Nov. 8, 1950 [Dec. 6, 1949], No. 31328/49. Class 129. In tea manufacture, fresh leaf is subjected to the stages of withering, bruising, twisting, fermenting, enzyme-killing and drying, or a selected sequence of these stages, while in a single closable rotatable container which can be heated and placed under vacuum or both. To manufacture black tea, fresh leaf 13 together with balls 14 or the like, is inserted in a container 1 through openings subsequently closed by airtight covers 8. A damp, oxygen-poor atmosphere is established by means of a vacuum conduit 7, so that breathing and fermenting of the leaf is prevented, and the container is rotated so that the balls bruise the leaf. Simultaneously, or subsequently with the container still under vacuum, the leaf is withered by externally heating the container, hot water or steam being sprayed on to it via nozzles w, st projecting through an adjacent arcuate screen 4. The vacuum is then released, and some or all of the balls 14 are removed at this stage or all are removed after fermentation. When the container is closed and revolving again, fermentation is effected by conditioned air from a conduit 6 blowing on to the leaf to contact it with oxygen. The revolution of the container causes the leaf to twist. After fermentation the air supply is cut off, and the enzymes are killed or inactivated by heating the leaf quickly, steam being supplied either externally or internally to the container. The latter is then cooled to below 140‹ F. by water sprays, and the leaf is dried by placing the container under vacuum and externally heating it with steam. By altering the sequence of treatment or omitting some stages oolong or green tea may be produced. Several containers 1 may be located within a cabinet partitioned into compartments, each housing one container and each closed by a sliding. door 2 in one wall, the opposite wall 3 being provided with the various supply conduits, so that one container may be treated either differently from, or the same as, another. Specification 654,799 is referred to.

April 24, 1931, No. 31369/30. [Class 34 (ii).] Granular m a t e - rials, such as salt, are dried in a vertical apparatus in which they alternately fall by gravity down inverted conical shoots 2, and are centrifugally thrown outwards by rotary discs 4, the centrifugal force having an upward component of increasing magnitude from disc to disc downwards, produced by giving increased concavity to successive discs. The inclination of the inverted cones 2 decreases d o w n - wards. The discs 4 are smaller-than the openings in the cones so that they may be withdrawn on the shaft 3. The discs carry centrifugal scrapers 11 to scrape the cones. The cones may also be provided with scrapers to scrape the discs. Hot air, or flue gases, is introduced at one or more points and may flow in co-current or counter-current. The cones may be hollow and heated by steam or hot water, or they may be electrically heated.

Abstract: 1,002,228. Liquid level control. JOSEPH LUCAS (INDUSTRIES) Ltd. Aug. 7,1964 [Aug. 8, 1963], No. 31376/63. Heading G1H. [Also in Division F2] A valve controlling the flow of liquid through an aperture 12 into a storage tank 10 and which closes when the liquid reaches a predetermined level comprises an actuating member 16 between a first space 17 in communication with the tank and a second space 18 communicating with a pipe 21 extending into the tank to the predetermined level, a one way valve 22 permitting fluid to flow from the second to the first space. The valve 12 is held in an open position by the pressure of liquid in the space 17 acting on the upper side of the member 16 until the liquid reaches the predetermined level and flows into the second space to act on the lower side of the member 16 and allow the valve to close. The one way valve may be situated in a passage of the valve body with its downstream side connected to the throat of a Venturi in the combined inlet and outlet 19. This arrangement prevents the valve from being held on its seat by pressure in the space 18 when a partly drained tank is to be filled. In a further modification, a vent 11 is replaced by a non-return valve in a downward extension of the pipe 21. A plunger 28 having a drain passage 29 for the space 18 enables the valve to be opened manually.

Abstract: 1388958 Drawing sheet glass GLAVERBEL 5 July 1972 [20 Aug 1971] 31485/72 Heading C1M In a method of manufacturing sheet glass by drawing a continuous ribbon from a pool of molten glass, gas displacing forces are applied at at least one pair of successive positions along the ribbon, the gas displacing force at one position being directed to impel gas in an opposite direction across the ribbon to the direction in which gas is impelled at the other position. The positions are separated by a distance such that the difference in glass viscosity is less than 10<SP>2.5</SP> poises and at least one of the positions is where the glass is at a viscosity between 10<SP>7.6</SP> and 10<SP>13</SP> poises. The gas displacing forces may be applied by ejectors similar to those described in Specification 1,388,957. Such ejectors may be situated in either the drawing chamber or an associated annealing shaft. Pairs of ejectors may be mounted on each side of the ribbon. In one embodiment (Figs 4 and 5), the operation of two pairs of ejectors 40, 42 and 41, 43 is controlled by a device 48 such that as one ejector 40 operates the other ejector 42 is inoperative, while the diagonally opposite ejector 43 of the second pair operates and ejector 41 is inoperative and vice versa. Mechanical means such as propellers may be employed as an alternative to ejectors. The process is applicable to the Pittsbury, Libbey-Owens and Fourcault processes and to processes involving the floating of molten glass on another molten material, e.g. tin.
