Title: Improvements in the manufacture of an initial material for the production of iron carbonyl
IPC: C01G49/16
Filed: 1952-02-08
Abstract: Iron carbonyl is produced by treating with carbon monoxide a comminuted initial material containing iron and sulphur which has been prepared by fusion followed by solidification wherein the fused material is cast in layers not thicker than 3 centimetres and quenched either by a water spray, a current of air, by water-cooled moulds or by using iron plates as lining for the casting bed.  A sulphur content between 2 and 7 per cent. is preferred in the solidified product.  Scrap iron and pyrites or iron sulphide from a previous carbonylation may be fused together or the sulphur may be supplied by copper sulphide, or iron oxide may be fused with pyrites, under reducing conditions, if desired with the addition of sodium sulphate and slag formers. Carbonylation may be effected at 200-220 DEG C at 200 atmospheres pressure, the grain size of the iron sulphide being 5-10 millimetres.
Patent GB-784831-A (GB)
Title: Improvements in processes in which inhibition of the action of proteolytic enzymes such as papain is desirable
Inventor: LEARMONTH ERIC MITCHELL
IPC: A23L7/104
Filed: 1952-02-08
Abstract: In processes involving proteolysis by enzymes such as papain and cathepsin which are inactivated by oxidizing agents and activated by reducing substances, particularly substances having-SH groups, the action of the enzyme is retarded or suppressed by incorporation of radicle and/or spermoderm tissue of raw leguminous seeds or an aqueous extract of such tissue(s) prepared without destruction of the rawness.  Rawness connotes presence in the tissue of a papain enzyme inhibiting factor, which is quickly rendered ineffective by heating at 100 DEG  C.; the tissue is therefore from seeds which have not been heated, and preparation of an aqueous extract of the tissue, and any concentration or drying of such extract, is effected at low temperature.  The leguminous seeds are exemplified by soya beans, peas, haricot and broad beans.  The spermoderm includes sub-epidermal tissues and excludes cotyledon epidermis.  By incorporation of the ground tissue or tissue extract in bread doughs of freshly-milled, chemically-untreated wheat flour, loaves of greater volume are obtained, since gluten degradation by yeast-activated proteolytic enzymes naturally present in the flour, and by the proteolytic enzymes of any added malt, is prevented.  Ground tissue may be employed in amounts of 0.1-1.0 per cent of the flour.  Specification 784,832 is referred to.

Abstract: 263,650. Technicolor Motion Picture Corporation, and Weaver, E. A. Feb- 8,1926. Drawings to Specification. Colour photography; toning.-The opticaldensity gradations in the shadow portions of dye-absorptive photographic images are made at least as great as in the half tone portions; the coloured images may be used for " black and white " or colour kinematograph projection, for printing by imbibition, &c., and they may be in the form of relief. The images may be produced by dyeing the film with a dye which is more absorptive to light of short wave length, and by printing with a mixture of lights, consisting, for example, of a light of short wave length and one of greater wave length. The dye may be sharp-cutting, and may be used in the maximum quantity which the film will retain in non-crystalline form in the process of drying. The dye may consist of naphthol-yellow, or quinoline-yellow, or a mixture of the two. The crystallizing tendency of the dye may be counteracted by the addition of a restrainer, and, in the case of naphthol-yellow, quinoline-yellow may serve as the restrainer. The invention mav be employed in conjunction with the invention described in Specification 263,331.

Electrical components of a telephone handset or base unit are located in a volume defined by a pair of mating shells and sufficient flowable adhesive hardening substance is applied within the volume to bond the shells together in mating relationship and encapsulate the electrical components. Unribbed plastics shells 11, 12 of a handset (Fig. 1) locate a receiver and a transmitter, there being a keyset (22), Fig. 2 (not shown), disposed in an opening (17) on the underside of shell 11 adjacent the receiver 20. Two glass substrates (23, 24), Fig. 2, cemented back-to-back support a thin film integrated circuit preferably integral with the keyset (22). A flexible printed circuit 25 connects the components. The components are located in the shell 11 with adhesive. The shells 11, 12 are placed in alignment and a metered quantity of two-part liquid polyurethane is introduced into shell 11 through an injector 31, after which the shells 11, 12 are mated. Foam 30 flows around the components and fills the open space within the cavity, forming chemical bonds with most of the materials with which it comes into contact and locking the shells 11, 12 together. The fully cured foam is rigid but provides mechanical shock isolation while reducing the possibility of broken leads. A base (Fig. 3) comprises plastics shells 41, 42. Shell 41 has a platform 44 at one end below which is a tone ringer resonant chamber 45. Upon the platform 44 is a thin film integrated circuit 46. A circular rib 47 covered by a cap 62 defines a chamber for housing the ringer (not shown). A switch hook 48 is mounted to protrude through an aperture 49. A housing 50 has contacts 51 of a line cord. Switches 52, 53 control the ringer, e.g. by changing the beat rate. A rear wall 54 forms a space 55 housing a retractable handset cord mechanism and associated contacts 58. Circuit connections are made by a flexible circuit 59. The components are secured and mechanically isolated by foamed material introduced through injector 31 which bonds the shells 41, 42. Additional weight is provided by lead shot or graded gravel 60 firmly held by the foamed material.

Abstract: 1,161,965. Production of ammonium sulphate. CONTINENTAL OIL CO. 24 Jan., 1968 [27 Feb., 1967], No. 3808/68. Heading C1A. Ammonium sulphate is produced from a sulphur dioxide containing gas by passing the gas through a solution of an amine having a dissociation constant greater than that of ammonia in an alcoholic solvent in which the amine and the corresponding amine sulphite and sulphate are soluble but in which ammonium sulphate is not soluble, in the presence of a stoichiometric amount of water to form an amine sulphite, oxidizing the amine sulphite to amine sulphate, and reacting the amine sulphate with gaseous ammonia to precipitate ammonium sulphate which is recovered. The amine may be acylic, carbooyclic or heterocyclic and many examples are given having pKa values in the range 9.80 to 11À42. Preferred alcohols are C 1  to C 6  aliphatic ones and suitable ones are listed. In an example an ethanolic solution of diethylamine is used and, following the separation of ammonium sulphate in the final step, this solvent and amine are recycled to the adsorption stage. Air or oxygen is used as oxidant, in the presence of a catalyst if desired. A suitable arrangement of apparatus is described.
