Void [Published under Sect. 91 of the Act]. Yeast.-In preparing yeast by the aeration method, the starting yeast is first treated with moderate aeration in a culture medium having an acid reaction and rich in nitrogenous substances so as to invigorate it and obtain slight reproduction. The mixture is afterwards diluted and then, with vigorous aeration, the ordinary nutrient solution, prepared for example from molasses, is added continuously or periodically at the rate at which the nutrient substances are consumed. The acid reaction of the preliminary culture medium mav be obtained by addition of sulphuric acid or by the growth of lactic acid bacteria. Nitrogenous substances may be supplied by addition of ammonium sulphate. Superphosphate of lime may also be added.

Title: Recovery of potassium chloride
IPC: E21B43/28
Filed: 1963-02-07
Abstract: 1,002,640. Solution mining. PITTSBURGH PLATE GLASS CO. Feb. 7, 1963 [Feb. 28, 1962], No. 5104/63. Heading E1F. Potassium chloride is recovered from two deposits A and B separated by an intervening sodium chloride-rich, potassium chloride-lean deposit C, the deposits being disposed A above C and C above B, by drilling a hole through the three deposits and extracting Kcl with water from deposits A and B simultaneously. In Fig. 1 pipe 2 is disposed concentrically in cased borehole 1. Water or unsaturated Nacl-Kcl solution is fed down I and Nacl-Kcl solution is withdrawn via 2. An inert immersible fluid e.g. hydrocarbon oil is fed in with the water in amounts up to 10 1bs. fluid per cubic foot of salts withdrawn to form protective layer 6 at the top of cavity 8. When the size of cavity 8 exceeds 5,000 cu. ft. the casing is perforated at 9 to allow inflowing water or brine to penetrate the upper deposit. The levels of the roofs of the cavities are raised at a rate not greater than 1 foot per 100 to 5,000 tons of Kcl withdrawn by controlling the rate of flow of water and the amount of oil fed in. In a preferred embodiment (Fig. 2, not shown) a pair of boreholes is used. Water or brine at a temperature 10‹ to 40‹F. higher than the temperature of the Kcl solution in the cavity is fed in by one borehole and Nacl-Kcl solution is removed by the other. The incoming borehole may be plugged at 9 to divert essentially all the water to the upper cavity and so develop it. Oil can then be made to reach cavity 8 as well as the upper cavity by inserting a pipe through the plug so that it terminates at a point below 9. Specification 945,220 is referred to

Patent GB-718688-A (GB)
Title: Improvements in or relating to new pyrimidine derivatives
Filed: 1953-02-24
Abstract: The invention comprises 2-amino-5-(p-chlorophenyl)-6-ethylpyrimidine substituted in the 4-position by -NR1R2, in which R1 is p  C1-C4 alkyl, R2 is C2-C4 alkyl or R1 and R2 together form a heterocyclic group with the nitrogen atom; also salts of these compounds.  These are made by condensing the corresponding 4-halogen compounds with HNR1R2 or a salt thereof.  The 2-acylamino derivative may be used as starting material, the acyl group being hydrolysed during or subsequently to the condensation.  When the free amine HNR1R2 is used, this is taken in excess and the reaction carried out at 120-150 DEG  C. either under pressure, in a low-boiling solvent if desired, or at atmospheric pressure in a high-boiling solvent, the amine being added in successive small portions.  By using a salt of the amine HNR1R2 the reaction may be conducted at about 200 DEG  C. in the absence of a solvent.  The products and their salts have anti-malarial and amoebicidal activity.  Examples show the production of 2 - amino - 4 - (di - n - butylamino) - 5 - (p - chlorophenyl) - 6 ethyl - pyrimidine and its hydrochloride, 2-amino-4-piperidino - 5 - (p - chlorophenyl) - 6 - ethylpyrimidine and 2 - amino - 4 - (di - n - propylamino) - 5 - (p - chlorophenyl)-6-ethylpyrimidine.  The starting materials may be prepared by condensing ethyl a -(p-chlorophenyl)-propionylacetate with guanidine to give 2-amino-4-hydroxy - 5 - (p - chlorophenyl) - 6 - ethylpyrimidine, N-acylating if desired, and replacing the hydroxy group, e.g. with phosphorus oxychloride.

Title: Improved process for preparing curry and packing it in tins
IPC: A23L27/10
Filed: 1938-02-19
Abstract: A curry is prepared by boiling a preparation of onions, coriander seeds, dried chillies and turmeric mixed with ground methi (fenugreek) seeds, cummin seeds and mustard seed in vegetable oil, cooling and adding fresh fish or fresh meat thereto.  The mixture may next be placed in tins and boiled, e.g. for 40-50 minutes at 240-250 DEG  F., and then cooled and the tins sealed and sterilized, e.g. by heating at 240-250 DEG  F. for 20-30 minutes.  As described, the coriander seeds, dried chillies and turmeric are mixed, ground and then formed into a paste with water.  A mixture of vegetable oil and onions cut into small pieces is boiled for 10 minutes, the paste is added and the product boiled for another 10 minutes.  Methi, cummin and mustard seeds, which have been mixed, roasted until they become brown, and ground, are then added, together with pepper and common salt. This mixture is boiled for 20 minutes with addition of water to prevent scorching, and aromatic leaves such as sauropus albicans are then added with more water, followed by boiling at 220-240 DEG  F. The temperature is next reduced to 180 DEG  F. at which it is maintained for half an hour, and the product allowed to cool for some hours.  Fresh fish which has been cleaned, washed, and dried for a few minutes in the sun is added to the amount of 25-30 per cent to the product, and the mixture inserted in tins and subjected to the boiling, sealing and sterilizing steps.  The cans may be coated with colourless enamel prior to labelling and packing.  An example of the proportions of the ingredients used is given.  Meat may be added in place of the fish.

Title: Method for making organo-substituted tetrahydroxydiborons and polymers therefrom
IPC: C07F5/02
Filed: 1960-02-15
Abstract: A polymeric material having at least 5 boronboron bonds and having recurring -B(OR) groupings (where OR is a radical derived, by removal of the hydroxylic hydrogen atom, from an alcohol, a phenol or 8-hydroxyquinoline) is made by heating a tetra-alkoxydiboron, tetraaryloxydiboron or tetra-(quinoline-8-oxy) diboron obtained by reacting a tetra-alkylaminodiboron or tetra-arylaminodiboron derived from a primary or secondary amine with an alcohol, a phenol or 8-hydroxyquinoline.  The number of B-B bonds depends on the temperature and length of time of heating.  Tetraethoxydiboron when heated for six hours at 50 DEG -100 DEG C. gives a polymer having about ten boron-boron linkages.ALSO:The invention comprises tetraphenoxydiboron and tetra-(quinolin-8-oxy) diboron. Tetraalkoxydiborons, tetraaryloxydiborons and tetra-(quinolin-8-oxy) diboron are made by reacting a tetraalkylaminodiboron or tetraarylaminodiboron derived from a primary or secondary amine with an alcohol, a phenol or 8-hydroxyquinoline, respectively, such as alkanols with 1 to 8 carbon atoms, phenol, cresols, xylenols, mesitol, catechol, a -naphthol and 8-hydroxy quinoline.  The reaction is accelerated and can be conducted at lower temperatures with the addition of HCl, HBr or HF.  It is preferred to use one mole of boron compound to 4 moles of hydroxy compound and 4 moles of hydrogen halide. The products are useful as herbicides and chemical intermediates and form polymers on heating (see Group IV(a)).
