Title: Improvements in a process of making phosphoric acid and calcium cyanamide
IPC: C01C3/18
Filed: 1930-09-01
Abstract: Phosphate rock is treated with a carbonaceous reducing agent such as coke in an electric furnace, the volatilized phosphorus is separated from carbon monoxide by condensation, and is oxidized with air to give phosphoric anhydride and nitrogen, which latter is passed over the calcium carbide resulting from the reduction, after cooling and crushing, to form calcium cyanamide.  The oxidation of the condensed phosphorus may be effected under pressure while cooling, the product, cooled and precipitated, and if desired converted into orthophosphoric acid.  An excess of nitrogen is obtained which may be used for making nitrogenous products.

Title: Improvements in or relating to the manufacture of crystalline potassium penicillin
IPC: C07D499/16
Filed: 1948-10-07
Abstract: Crystalline potassium penicillin is manufactured by adding, with agitation, a solid material comprising mainly potassium penicillin to an organic solvent selected from monohydric aliphatic alcohols of 3-6 carbon atoms and mixtures thereof with aliphatic carboxylic esters, at a temperature not above about 85 DEG  C., thereafter bringing or keeping the temperature of the mixture within the range 40-85 DEG  C. and continuing agitation while crystallization of the potassium penicillin takes place, and finally separating the crystalline potassium penicillin. Preferably the solution temperature is within the range 20-80 DEG  C. and the crystallization temperature within the range 40-80 DEG  C., the latter being advantageously at least as high as the former. Preferred solvents (which are desirably substantially anhydrous), are n- and iso-propanol, n-butanol, fermentation amyl alcohol, n-hexanol and n-butanol/ethyl or amyl acetate.  The solid potassium penicillin used may be amorphous material obtained by freeze-drying or spray-drying aqueous solutions thereof, preferably of a potency of at least 800 units per mg., and the ratio thereof to the solvent may be between about 0.5 : 10 and 6 : 10 (preferably about 4 : 10) by weight When the ratio is between 4 : 10 and 6 : 10, it is desirable to dilute the mixture after crystallization with sufficient solvent to bring the ratio below 4 : 10.  The crystals of potassium penicillin may be separated (e.g. by filtering or centrifuging), after or preferably without cooling, and may then be washed and, if desired, recrystallized, e.g. by dissolving in aqueous n-butanol and then adding sufficient dry n-butanol (preferably in two or more stages at about 0 DEG  C.) to bring the concentration thereof to 95-99 per cent by volume, or by dissolving in aqueous acetone and adding dry acetone until the concentration thereof approaches or attains 99 per cent by volume. Examples illustrate various features of the invention. Specification 647,320 is referred to in the Provisional Specification.

Title: Improvements in vacuum dehydration
IPC: F26B5/06
Filed: 1945-10-09
Abstract: <PICT:0620573/III/1> Substances such as blood plasma or penicillin broth are dehydrated whilst in the frozen state, by exposing them to a pressure of less than 4.7 mm., compressing the evolved water vapour, and condensing it to liquid water in the early stages of the dehydration, and to ice in the later stages.  The dehydration is carried out in a chamber 10 which is connected, via a booster pump, to a condenser 60 and roughing pump 70.  The booster pump comprises an ejector nozzle 54 and a diffuser tube 32 which is cooled by cooling fluid circulating through the space 34 between the tube and casing 24. This pump is connected by conduits 52 and 56 to boiler 42 which contains a stable organic liquid of low vapour pressure which, when the pump is in operation, is heated by gas-heated tube 46. The substance to be dehydrated is introduced into trays 16, cooling fluid is circulated through condensing coils 62, and roughing pump 70 is started up.  When the pressure is of the order of 4.7 mm., the booster pump is put into operation.  The organic vapours from boiler 42 are ejected through nozzle 54 and entrain water vapour which has passed into the booster pump from chamber 10 through conduit 20.  The organic vapours are condensed on the walls of diffuser tube 32 and the liquid returns to the boiler through conduit 56.  The compressed water vapour passes on, and is introduced into condenser 60 through conduit 58.  The rate of flow and temperature of the refrigerating fluid in coils 62 is adjusted so that when the amount of water vapour given off in chamber 10 is large, it is condensed to liquid water and collected by funnel 72, but when the amount given off is small, i.e. at the final stage of the dehydration, it is condensed as ice on the coils 62.  When a fresh batch of material is to be introduced, valve 22 is closed and, before it is re-opened, chamber 10 is reevacuated by means of roughing pump 82.  The water vapour given off in the first stages of dehydration of the new batch melts the ice built up on coils 62 in the final stages of the previous dehydration. Specification 566,814, [Group XXVIII], is referred to.

Abstract: 630,357. Turbine blading. F A I R - WEATHER, H. G. C. (Svenska Turbinfabriks Aktiebolaget Ljungstrom). Oct. 7, 1947, No. 26964. [Classes 110(i) and 110(iii)] A blade ring for a radial flow elastic fluid machine such as a turbine or compressor in which the blades are provided with dovetail roots at one or both ends which are dimensioned to act as distance pieces and engage an undercut annular groove in a supporting ring and are retained therein by rolling over the sides of the groove has an annular protecting strip inserted between the sides of the groove and the dovetail roots to prevent marking of the sides of the groove and to distribute the pressure of the blades on these sides. A blade 2, Fig. 1, has a dove-tail root 3 which engages an undercut groove in a supporting ring 1 and is retained therein by rolling over the sides 4, 5 of the groove. During this rolling action the blades tend to twist as shown in Fig. 2 and the edges of the blade roots to cut into the sides of the groove. To prevent this, annular protecting strips 6, 7 are placed in contact with the sides of the groove. The strips which may be of metal or other material are preferably softer than the material in which the groove is formed. The strips 6, 7 may be separate strips or on the sides of a single strip joined by a part 10. Modifications in which the protecting strip is extended to protect the tops of the sides of the grooves and also to form a packing strip between the blade rings are also described.
