Title: Improvements in the production of solid greases
Filed: 1928-08-03
Abstract: 317,630. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 3, 1928. Lubricants.-Solid lubricants, greases, &c. are produced by heating tar, mineral, vegetable, animal or fish oil or mixtures of these, with bleached montan wax or a montan wax composition such as that described in Specification 296,145, and adding an aqueous solution of alkali hydroxide or carbonate to neutralize the free acidity. In examples, mineral oil which may be mixed with rape or train oil, is heated with montan wax which may be esterified or partly esterified and partly converted to a calcium salt, and sodium hydroxide solution added with stirring, to form, when cold, a solid lubricant.

Abstract: 1,199,267. Refrigerating. INDUSTRIE A. ZANNUSSI S.p.A. 2 May, 1969 [2 May, 1968; 11 Dec.,1968], No. 22613/69. Heading F4H. In a compression refrigerating system for cooling two environments, e.g. compartments of different temperatures in a domestic refrigerator or ice cream preserving cabinet, each environment has a separate evaporator 5, 10 and is fed alternatively with refrigerant from a common compressor 1 via a three-way solenoid valve 3. The valve position is governed by a first thermostat (not shown) in one environment which closes a switch in the electrical supply circuit both to the valve and the compressor when the temperature exceeds a predetermined figure to ensure flow of refrigerant to the evaporator 5 until the established limit is met whereafter the valve 3 operates to supply refrigerant to the evaporator 10. A second thermostat (not shown) located in the other environment operates a switch 14 to close a supply line by-passing the switch 13 to maintain current flow to the compressor. A non-return valve 6 is inserted between the evaporator 5 and the compressor and a capillary-restrictor tube (not shown) may connect the inlets of the two evaporators to ensure a partial flow to both evaporators simultaneously.

Abstract: 207,243. Thompson, W. P., (Townsend, J. R.). Aug. 21, 1922. Windows and the like, cleaning.-A brush 19 is supported in a holder 20 which is rotatably mounted at the end of a spring arm 1 bent at 2 to pass rotatably through the frame 7 of a motorvehicle windscreen and provided with a handle 12. In the horizontal position shown in Fig. 1, the wiper rests upon the weather-strip 23 along the upper edge of the lower panel 24. The brush is provided at one end with a stop 22 to prevent this end from passing below the arm 1, and when the handle 12 is raised the brush will traverse the screen and be brought horizontal by the upper edge of the frame 7. On the downward motion the tendency of the outer edge to lag will be corrected by the stop 22 so that the brush remains substantially horizontal and the moisture is lined vertically enabling subsequent accumulations of moisture to flow evenly downwards without obstructing the vision. If the lower panel has no weather-strip the brush may rest upon a clip fixed to the top edge of the glass.

Title: Process for the production of depolarising compositions from pyrolusite
IPC: H01M4/50
Filed: 1937-08-20
Abstract: 500,806. Batteries. I. G. FARBENINDUSTRIE AKT.-GES. Aug. 20, 1937, Nos. 22932 and 22933. Convention dates, Oct. 15, 1936 and Oct. 24, 1936. [Class 63] [Also in Group III] Improved depolarizing compositions are obtained from native pyrolusite which has been hydrated by a treatment with an alkaline aqueous solution of an alkali metal. or ammonium compound such as hydroxide, carbonate, or bicarbonate ; by treating it with a dilute acid or a solution of an acid salt to convert adsorbed alkali or ammonium compounds into easily soluble salts which are removed as by washing. In a modification such hydrated pyrolusite containing adsorbed alkali metal compounds is treated with a solution of an ammonium salt at elevated temperature and the product leached to remove the easily soluble alkali metal salt formed. Tho first process increases the content of water of hydration in the - hydrated pyrolusite and improves its depolarizing efficiency. The second process also leads to improved depolarizing efficiency but without increase in the content of water of hydration ; in addition the storage properties of the production improved. As dilute acids, hydrochloric and chromic acids may be used and as ammonium salts, the chloride or sulphates. Examples of operation arc given. The Specification as open to inspection under Sect. 91 comprises also the following subjectmatter : Hydrated manganese dioxide of any origin containing adsorbed alkali metal or ammonium compounds may be treated by the process of the invention; and the amount of acid or acid salt used for treatment is approximately sufficient to neutralise the adsorbed compounds. This subject-matter does not appear in the Specification as accepted.

[Class 2 (ii).] In the manufacture of viscose, cellulose material is treated with an alkalizing lye containing not more than 3 per cent of a di- or polyhydric alcohol which has no reducing action. Viscose solutions of reduced viscosity are subsequently produced. The di- or polyhydric alcohol may be glycol, glycerine, erythrite, mannite, or pentaerythrite. It is stated that the optimum addition for compounds containing three or more hydroxyl groups lies between 1 and 2 per cent and, for compounds containing two hydroxyl groups, between 2 and 3 per cent. Several successive immersion operations may be carried out on the same batch of cellulose material, and the desired effect is obtained even if the addition of polyhydric alcohol is made only to the first bath. After the immersion process, the alkali cellulose may be pressed and sulphided, or without being pressed it may be subjected to the action of carbon disulphide in presence of excess of alkali. Cotton or wood cellulose may be used and it may take the form of cotton linters, ordinary sulphite cellulose, or alpha-fibre cellulose. Specification 15752/10, [Class 2 (ii), Cellulose &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the addition of a small proportion of gluconic acid, saccharic acid, saccharinic acid, glyceric acid, glycerides, and sugars such as glucose to the alkalizing lye.
