Title: Improvements in or relating to leclanche cells and a depolarizer for these
IPC: F22B29/12
Filed: 1935-08-02
Abstract: A depolarizer for electric primary cells is obtained from a finely ground manganese ore by partial reduction of the surface of the particles and formation of manganites or poly-manganites thereon. Reduction may be effected by a manganous salt, hydrochloric acid, or sulphurous acid, with or without a ferrous salt, by heating at about 200 DEG  C. in the presence of hydrogen and treatment with an acid, or, in the case of an ore comprising lower oxides such as Mn3O4, Mn2O3, and/or MnO, by a solution of manganous salt formed by dissolving these lower oxides in an acid.  Formation of manganites may be effected by treatment with a solution or suspension of an oxide, hydroxide, or carbonate of an alkali or alkaline-earth metal, or with a solution of a manganate or permanganate; in the first case the surplus of manganese hydroxide and of the added oxide &c. is removed, as by oxidizing the manganese hydroxide with chlorine, hydrogen peroxide or a manganate or permangate, and dissolving the added oxide &c. in water or an acid, or by reacting the surplus hydroxide and oxide &c. with ammonium chloride.  A material of the type aXO, bMnO, cMnO2, yH2O lying around a core of natural manganese ore, wherein X is Ca, Ba, Sr, Mg, K, or Na, may be obtained.  When using the depolarizer in an electric primary cell, means may be provided in the electrolyte to protect the manganic ions generated by the depolarizer against decomposition, as by having a high concentration of anions therein, or adding salts, for example of hydrofluoric or phosphoric acid, which will form buffer salts. Specification 446,624 is referred to.

Class 122 (1). [Also in Group XXVII] In a reciprocating engine, particularly a twostroke internal combustion engine, the piston 4 is connected to its connecting rod 2 so that it is rotatable about its own axis which is offset in relation to the longitudinal axis of the rod, as by an amount e, Fig. 2, whereby, in operation, the horizontal component P of the connecting rod thrust applies a torque Pe about the piston axis which, if arranged to exceed the frictional resistance, causes either rotation or oscillation of the piston in its cylinder. The ball end 1 of the connecting rod 2 is arranged in a two-part cup 3 eccentrically mounted in a rotatable socket 5, the cup and socket being retained in position by a supporting ring 11 secured by a lock-nut 12. Ball thrust bearings may be arranged between the ends of the socket and the piston. The eccentric mounting of the piston may also be obtained by offsetting the longitudinal axis of the piston in relation to that of the socket 5 which latter may also be offset in relation to the connecting-rod axis. The piston is cooled by fluid supplied through the connecting rod and circulated via discharge passage 8, chamber 6, ducts 9, chamber 7 and outlet ducts 10, the ducts 9 and 10 being dimensioned in relation to each other and the passage 8 so that chambers 6 and 7 are always completely filled. The invention may be applied to a piston connected to its connecting rod by a gudgeon-pin housed in a rotatable socket. The rotational movement of the piston may be used for controlling purposes.
