Title: Improvements in or relating to the dehydration of potatoes
IPC: A23L19/15
Filed: 1945-02-05
Abstract: A process of producing mashed potato powder comprises cooking and mashing, freezing the mash, thawing at a temperature not exceeding about 10 DEG C. mechanically separating water and drying to the desired moisture content.  In a modification the potatoes after cooking may be frozen whole or partially broken and then thawed, mashed and subsequently or simultaneously separating water and dried. The separated water contains 3-4 per cent. of solids which may be recovered, e.g., by spray drying and incorporated in the potato powder.  In an example cooked potatoes are mashed preferably while hot, e.g., by forcing through a perforated plate and placed on a travelling band passing first through a freezing chamber and frozen hard preferably below-10 DEG C. and then after breaking the material into small pieces through a contiguous thawing chamber operated by warm air.  Thawing may be done solely or accelerated by mixing the frozen mass with warm water the temperature of the mixture not exceeding 8-10 DEG C.  After thawing water is separated by a screw press or centrifugal hydro-extractor until at least 33 per cent. total solids remain and then the material is dried after sieving and reduced to its desired size when drying is nearly completed.  In a modification potatoes are cooked in their skins, crushed by rollers and frozen at-15 DEG C. for 24 hours, broken into small pieces and mixed with a suitable quantity of warmed water or aqueous liquid expressed later in the process.  The mixture is then sieved and the water removed, e.g., by centrifuge followed by screw press and then broken down and dried preferably in a pneumatic type drier at 50-60 DEG C.  Specifications 542,125 and 566,167 are referred to.

Title: Improvements in or relating to the production of benzene ortho dicarboxylic acid anhydrides
IPC: C07C51/265
Filed: 1949-02-02
Abstract: ortho-Aliphatic benzene monocarboxylic acids are prepared by oxidizing an ortho-dialiphatic benzene at an elevated temperature in the liquid phase with an oxygen-containing gas in the presence of a soluble oxidation catalyst which is a compound of a multivalent metal capable of changing its valency at the reaction temperature.  If it is desired to produce the corresponding benzene ortho-dicarboxylic acid anhydrides, the monocarboxylic acid obtained above is oxidized in the vapour phase with an oxygen-containing gas in the presence of a contact type oxidation catalyst.  It is stated that for the production of the dicarboxylic anhydrides the use of a liquid phase process followed by a gaseous phase process offers considerable advantages. Catalysts mentioned for the liquid phase process are cobalt, manganese, chromium, nickel and lead which are used in about 0.5 mol. per cent concentration and in a temperature range 200-. 300 DEG  F.  Catalysts for the vapour phase oxidation are metals of Groups V and VI of the Periodic System, particularly vanadium catalysts, used in a fixed bed, fluidized fixed bed or fluid type of system and in a temperature range of 500-1400 DEG  F.  In an example, ortho-xylene and cobalt naphthenate containing 0.01 mol. per cent cobalt, are passed through a column at 250 DEG  F. in the presence of air for about 6 hours to form ortho toluic acid which is then oxidized in the vapour phase in the presence of vanadium pentoxide coated on silicon carbide and air at 390 DEG  F., to produce phthalic anhydride.

Title: Improvements relating to electrical converting circuits employing discharge tubes
Inventor: SMART DAVID LORIMER
IPC: H02M5/00
Filed: 1953-02-10
Abstract: 738,851. Converting. ENGLISH ELECTRIC CO., Ltd. Feb. 5, 1954 [Feb. 10, 1953], No. 3688/53. Class 38 (2). A frequency converter having for each phase of the supply a pair of vapour discharge paths with control grids excited in antiphase at the output frequency, comprises means whereby each pair of control grids can be energized substantially simultaneously at desired instants. In a circuit wherein a load 18 is supplied with high-frequency current from a three-phase transformer winding 10 operating 'at mains frequency, each supply phase is connected to the centre point of a load transformer winding 14 whose ends are joined to two anodes 21, 22 of a six-anode mercury vapour discharge tube 20. Associated with the anodes 21, 22 are grids 23, 24 energized at the output frequency and grids 25, 26 energized at input frequency. The grid impulses of output frequency are derived from a square wave generator 42 and applied to the grids when thyratron 45 is conducting, there being sufficient voltage drop across impedance 41 to remove the biasing effect of negative terminal 43 which is connected to the thyratron cathode. When thyratron 45 is non-conducting the negative bias from terminal 43 applied to grids 23, 24 through rectifiers 33, 34 prevents firing of anode 21, 22. The anode of thyratron 45 is energized through rectifiers 46, 47 from two phases of winding 12 of the supply transformer over a time which includes the firing range of anodes 21, 22. The thyratron grid is energized from supply transformer 13 and potentiometer 48 whose setting is varied to alter the firing instant of thyratron 45 and thereby the point in the input cycle at which tube 20 fires to vary the power output of the wavemeter. To initiate converter operation, relay 49 is closed with repeated opening and closing as described in Specification 691,072. By varying the potentiometer 48 setting in accordance with the output current or voltage, variations in these quantities may be reduced. In a modification rectifiers 33, 34 are replaced by a double triode.
