Title: Improvements in or relating to process for the manufacture of therapeutic useful preparations of iron
IPC: A61K31/295
Filed: 1960-04-29
Abstract: A therapeutically useful ferric hydroxide-partially depolymerized dextrin complex is obtained by mixing an aqueous solution of a water soluble dextrin fraction having an average intrinsic viscosity at 25 DEG C. of from 0,025 to 0,075 with an aqueous solution containing ferrous or ferric ions or a suspension of ferrous or ferric hydroxide and an excess of alkali, heating the reaction mixture to form the ferrous or ferric complex and in the former case oxidizing to give the ferric complex. The initial dextrin is preferably obtained by roasting starch in the presence of an acid. In a typical example (No. 2) dextrin is heated in water at 75 DEG C. and firstly ferric hydroxide solution and then caustic soda solution added slowly. After cooling the pH is adjusted to 6,2 and ethyl alcohol added and the solution rendered isotonic by the addition of sodium chloride and then filled into ampoules. Phenol may be added as a preservative. Specification 748,024 is referred to.ALSO:A therapeutically useful ferric-hydroxide-partially depolymerized dextrin complex is obtained by mixing an aqueous solution of a water soluble dextrin fraction having an average intrinsic viscosity at 25 DEG C. of from 0.025 to 0.075 with an aqueous solution containing ferrous or ferric ions or a suspension of ferrous or ferric hydroxide and an excess of alkali, heating the reaction mixture to form the ferrous or ferric complex and in the former case oxidizing to give the ferric complex.

Title: Recovery of sulfur trioxide by distillation while controlling a process variable in response to the dielectric constant
IPC: C01B17/90
Filed: 1962-08-23
Abstract: Liquid sulphur trioxide is produced by distilling oleum and controlling the distillation according to the dielectric constant of the product or the liquor remaining during the distillation. The distillation is preferably done in at least two stages, the dielectric constant of the product or liquor remaining in the second stage being used for control purposes.

The free sulphur trioxide content of the oleum may be between 5 and 65% by weight and the temperature of the distillant coolant is between 28 DEG and 37 DEG C. A stabilizer may be added to the liquor or product, e.g. a carbonyl halide or carbon tetrachloride. Sulphur trioxide of very low acid content, e.g. down to 20 to 30 p.p.m., is obtained.ALSO:Liquid sulphur trioxide, mixed with a small proportion of sulphuric acid, is produced by distilling oleum, and the impure sulphur trioxide is then re-distilled in a second still which is controlled by a device for measuring the dielectric constant of the liquid in the second still, or of the final product. The control prevents the accumulation of acid in the second still, and is effected either by running off the liquid from the second still, or by varying the heat input to the still. The measuring device preferably comprises a pair of platinum electrodes, immersed in the liquid, which are connected to a relay via a variable frequency oscillator circuit adjusted to operate the relay at a given dielectric constant.

Title: Icemaking machine
IPC: F25C1/06
Filed: 1967-09-18
Abstract: Ice-making apparatus comprises a singlespeed constantly operating centrifugal pump 24 for circulating water in a closed circuit including a refrigerant-jacketed tube 30, and a pressuresensitive switch 86 connected to the water line 30A upstream of the inlet of tube 30, the switch being operable to initiate thawing of tube 30 by hot gaseous refrigerant when the pressure in line 30A rises to a predetermined value consequent on the formation of a desired quantity of ice in the tube. The loosened ice is forced into a bin 40 by the continued pressure of the water from the pump. The latter supplies water at a rate in excess of that required to maintain all of the water in the tube 30 in circulation during the freezing step and the rate of flow is limited by a restrictor valve 29 upstream of switch 86. A further pressure switch 90 is arranged to terminate refrigeration if the pressure at the discharge side of the pump falls to a predetermined value. Tube 30 is of helical form and undergoes an abrupt change of direction at its outlet section 34 so that the hydraulically ejected rod of ice is broken into short cylindrical sections as it passes through said section. Bin 40 may contain a device for shutting down the apparatus when the ice has reached a predetermined level. Water from bin 40 drains into a tank 12, to which make-up water is added under the control of a float 14, and returns to the pump through line 22. The refrigeration system comprises a compressor 104, condenser 110, receiver 114 and expansion valve 116. A hot-gas solenoid valve 126 is provided in a line 124 leading from the compressor discharge side for supplying hot gas to an intermediate point of the jacket of tube 30 through line 120 and to the inlet end of the jacket through checkvalve 122.
