Patent GB-896950-A (GB)
Title: Improvements in and relating to tea extracts and processes for preparing them
IPC: A23F3/16
Filed: 1959-04-24
Abstract: An aqueous extract of green tea in which the enzymes are inactivated is heated with bruised fresh tea leaves whose enzymes are not inactivated in the presence of oxygen for sufficient time to develop the tea colour, aroma and flavour desired, after which the mixture is heated to stop the reaction.  Preferably the fresh or manufactured green tea is extracted with water at high temperatures to remove substantially all the desired soluble solids and used soon after preparation.  The fresh tea leaves which may include leaves preserved by refrigeration or other means are bruised, e.g. by macerating, folding, rolling, milling or grinding, to release the enzymes. During preparation, the temperature should not exceed about 38 DEG C. and preferably should be about 27 DEG  C. and dry ice may be added to refrigerate the newly harvested leaves before comminution takes place.  The process should be carried out below 38 DEG  C. but at substantially below 27 DEG  C. the reaction is slow and the time is regulated to produce the desired product, e.g. a black tea concentrate or an Oolong tea concentrate, the extract being continually agitated.  If a high concentration of bruised leaves is used, the conversion is more rapid but a 3.6% concentration is sufficient.  Conversion is stopped by heating to inactivate the enzyme.  The extract may be used directly with dilution as a beverage or may be concentrated or dried to a powder.  The results of a series of tests and some examples are given.

Patent GB-144370-A (GB)
Abstract: 144,370. Waller, P. H., and Nordman, B. E. March 6, 1919. Station, stopping-place, and like indicators; displaying announcements.-An automatic indicator for exhibiting a series of notices in succession. described in connexion with a station indicator carried on a train, comprises means whereby a predetermined notice may be prevented from being exhibited, and the operation of a step-by-step device which would normally exhibit it is caused to show the next succeeding notice not thus cancelled, and an alternative notice is exhibited in place of the cancelled notice, preferably during the exhibition of the whole series. The notices " Not stopping at " and " Next station " above and below the names of the stations A, B, C, D, E are illuminated by lamps A<10>-E<10> and A<4>-E<4> respectively. The lamps A<4>-E<4> are lit in turn by a switch K engaging contacts A<1>-E<1>, the switch being operated by any means, e.g. devices on the track. Between the lamps A<4>-E<4> and the switch K are manually-controlled switches A<2>-E<2>, having each three contacts, such as C<3>, C<5>. When travelling in the direction A to E and when all the stations are to be stopped at, all the switches A<2>-E<2> would be placed on the contacts A<3>-E<3>, thus lighting up the lamps A<4>-E<4> in succession as the switch K moved along contacts A<1>-E<1>, one at a time between each station. If, say, the station C is to be missed, the switch C' is placed on the contact C<6>, so that when the switch K reaches the contact C' the station D will be indicated as the " Next station," and will remain so when the switch K moves on to the contact D'. Had the train been travelling in the reverse direction the switch C<2> would have been placed on the contact C<5>. To illuminate the " Not stopping at " signs, a series of switches A<7>-E<7>, mechanically connected with the switches A<2>-E<2>, each to each, are provided, having two contacts, e.g. C<3> -C<9>, so that when the switch C' is moved either way to skip the " Next station " indication under station C, the switch C' is pulled over to light up the lamp C<10> showing the " Not stopping at " sign over station C. To avoid having to reverse the motion of the switch K when the journey's end is reached, further contacts d<1>, c<1>, b are provided, connected respectively to the contacts D', C<1>, B<1>. When the train reverses at an intermediate station, the switch K is manually operated to bring it to the correct contact.

Abstract: 1,008,195. Recording defects; associated working. COMPAGNIE DE SAINT-GOBAIN. April 16, 1962 [April 14, 1961], No. 14623/62. Heading G5R. [Also in Divisions G1 and G3] Blemishes in a continuous glass sheet 1 are detected by transverse optical scanning means 2, 3, Fig. 1, and an electronic switch 3 feeds an analogue signal of amplitude related to the seriousness of the blemish to an array of recording heads 4 transverse to a magnetic tape 5. The tape is driven in synchronism with the glass sheet and a longitudinal track 5a in conjunction with the heads 4 provides a real location of the recorded signals. Several scanners may inspect the glass from differing aspects and the outputs all fed to the heads 4, which will record the amplitude of the most significant blemish. When the sheet is to be cut up, at a later stage, the tape is played back in synchronism with the advance of the sheet and the cutters are controlled (by means not detailed) to avoid the inclusion of faulty areas in the glass (such as inside the dotted-line area of Fig. 2) in the pieces cut. On playback, the pulses read-out by the start and finish of a record flux pattern due to an extended blemish, are stored in flip-flops 12 and these are analysed by shaping circuits to start and stop a clock means 25 whose output represents the extent of a blemish in digital form.

Patent GB-680985-A (GB)
Title: Improvements in and relating to the causticisation of sodium sulphite
IPC: C01D1/20
Filed: 1951-06-21
Abstract: Water is extracted from an aqueous mixture obtained by causticizing sodium sulphite with lime by treating with anhydrous sodium sulphite and cooling if necessary to below 33.4 DEG C so that crystalline sodium sulphite hydrate is formed.  In a continuous process a solution of caustic soda and sodium sulphite from the causticising unit, already freed from calcium sulphite, is fed to a dehydration vessel where anhydrous sodium sulphite is added. The resulting mixture is passed to a cooled crystallizing vessel and the crystals of sodium sulphite hydrate are separated, e.g. by centrifuge.  About 1/4 of the separated crystals are dissolved in water, with consequent cooling due to the positive heat of solution of the hydrate, and the cold solution is fed to the causticizing unit through the jacket of the crystallizing vessel to effect part of the necessary cooling. The remaining separated crystals are heated to above 33.4 DEG C to form a saturated solution of sodium sulphite, which is returned to the causticizing unit, and a deposit of anhydrous sodium sulphite, which is returned to the dehydration vessel.  The filtrate from the crystal separation is evaporated, so that the remaining sodium sulphite is deposited as an anhydrous solid, which is returned to the dehydration vessel, and concentrated caustic soda is formed.  The sodium sulphite may be added before separation of calcium sulphite or may be added in stages.  The calcium sulphite precipitate may be washed and the washings used for making fresh sodium sulphite solution.
