Filed: 1933-04-12
Abstract: 405,143. Salt-glazing ceramic ware. GIBBONS BROS., Ltd., Dibdale Works, Dudley, Worcestershire.-(Dressier, C.; Rue D'Aleray, Paris.) April 12, 1933, No. 10914. [Class 51 (ii).] In a salt-glazing tunnel kiln the salt is introduced with the fuel, and the glazing vapours and heating gases are passed downwards in contact with the goods, a portion being withdrawn from the kiln chamber for recirculation. The kiln described comprises preheating, firing, glazing, and cooling zones, and the firing- zone is heated by burners 21, Fig. 6, slightly below the level of the goods platform on the trucks. The burners are adapted to burn a fuel air mixture and are axially adjustable relatively to Venturi orifices 25 in nozzle blocks 24, so that the suction effect on preheated secondary air from a flue 26 can be controlled. The products of combustion are exhausted through longitudinally-spaced damper-controlled ports in a widened section of the preheating-zone. In the glazing-zone a combustion chamber 45, Fig. 2, defined by depending baffles 46 is formed above the goods, and is fired by burners 51 to which salt is fed from the hopper 55. The glazing-gases are withdrawn through passages 58, and the main portion 5 exhausted to flues 59 under control of dampers 61, while a portion is returned to the combustion chamber through vertical dampercontrolled ducts 64, to which secondary air may also be delivered from the flues 26. In the cooling-zone the walls of the kiln are formed with passages through which air is drawn by a fan so that it will be preheated before delivery into the exit end of the kiln chamber. The air admitted to the cooling-zone is withdrawn into the flues 26. The truck superstructure on which the goods are sup ported consists of girder-shaped slabs 40, Fig 5, providing horizontal heating-gas passages in communication with the kiln chamber through slots 43. In a modification (Figs. 9-11, not shown) the salting burners deliver upwards into inclined passages opening into the kiln chamber above the top of the ware.

Title: Improvements in and relating to the production of ascorbic acid
Inventor: ISHERWOOD FREDERICK ARTHUR
IPC: C07D307/62
Filed: 1953-04-21
Abstract: A process for the production of L-ascorbic acid from one or more of the g -lactone, and methyl, ethyl and propyl esters and amides of L-gulonic or of L-galactonic acid comprises oxidizing in the presence of oxygen one or a mixture of such substances by means of a group of enzymes obtained in an extraction medium at a pH between 6.0 and 8.5 from animal or vegetable tissues, such group being one which transfers electrons from sugar lactones to molecular oxygen and includes a dehydrogenase enzyme and cytochrome oxidase or similar enzymes, but not including substantial proportions of enzymes which oxidize ascorbic acid. The gamma lactones or esters of L-gulonic or L-galactonic acid may be prepared in situ by the reduction of the corresponding derivatives of D-glucuronic and D-galacturonic acids catalysed by the action of an enzyme system in the whole cell extract.  The enzymes are found in mitochondria occurring in seeds and animal tissues, algae and yeasts, pea-seeds being one suitable source. The extraction medium is suitably a cooled solution of an organic nonelectrolyte having an osmotic pressure sufficient to prevent disintegration of the mitochrondria, e.g. sucrose, mannitol, glycerol and urea, and also containing sufficient phosphate or arsenate to give it a pH between 6.0 and 8.5 together with a trace of a magnesium salt.  The concentration (with sucrose) is preferably 0.4 M with plants tissues and 0.25 M with animal tissues, that of the phosphate or arsenate being 0.1 M and of the magnesium salt 4 X 10-3 M.  In examples: (1) pea-seeds after 12 to 48 hours germination in water are extracted at 0 DEG  C. and pH 7.5 with 0.4 M sucrose containing 0.1 M phosphate and 0.1 per cent magensium sulphate. After removing starch and cell debris the solution (Extract A) may be centrifuged giving a precipitate (Extract B) containing the active elements.  The g -lactone of either L-galactonic or L-gulonic acid is then incubated with Extract A or Extract B at 37 DEG  C. to give L-ascorbic acid.  After 4 or 5 hours additional g -lactone may be added for the production of further L-ascorbic acid.  The product may be isolated by ion-exchange; (2) rat-liver is homogenized in 0.25 M sucrose solution.  After removing cell debris the solution is centrifuged at 20,000 g., the precipitate is suspended in 0.25 M sucrose/phosphate buffer, and employed in a similar incubation process to (1).  Methyl, ethyl or propyl esters or amides may also be used as in Example (1).

Abstract: 915,361. Rectifying. BROOKHIRST IGRANIC Ltd. April 1, 1959 [April 3, 1958], No. 11032/59. Class 38 (2). A polyphase full-wave rectifier network includes pairs of controlled rectifiers conductive at the same time in each phase and a timeconstant circuit associated with the rectifiers in each phase, the time-constant circuit having different charging and discharging time constants, and being arranged so as to prevent conduction through a rectifier in another phase during conduction in its own phase. Rectifiers T1, T2, T3 are controlled by controller C to conduct in sequence and when one of these rectifiers, say T1, conducts the voltage drop across the associated resistor R4 charges condenser C1 so as to apply a negative bias to the grid of rectifier T4<SP>1</SP> to prevent conduction thereof due to back E.M.F. from an inductive load. Condenser C1 discharges slowly through resistor R2. When T4<SP>1</SP> is required to conduct in its correct sequence, its grid is positively biased through potential divider R1, R2. In a modification, Fig. 2, transformers PT1, PT2, PT3 are provided so that an additional positive bias is applied to the grid of that rectifier which is required to conduct. The primary winding of each transformer is connected across a resistor R4. When T1 conducts, T4<SP>1</SP> is biased to cut-off by C1 as before, but the grid of T6<SP>1</SP> receives an additional positive bias through PT1. Specification 876,888 is referred to.
