Title: Elastic Connecting Rods for Tension or Compression in Motor Road Vehicles.
Inventor: FROHNHAEUSER CARL
Filed: 1901-06-12
Granted: 1902-05-22
Abstract: 11,987. Frohnhaeuser, C., [Hagen, R.]. June 12. Connecting-rods.-Relates to elastic connecting- rods, either for tension or compression, especially suitable for use in connection with explosion engines operating through variable-speed gear in motor cars. Fig. 1 shows, partly in section, a tension connecting-rod. In a casing h forming part of the rod f is enclosed an india-rubber or felt buffer g, which is interposed between the end of the casing and a piston attached to the other part i of the rod. In order that no stress beyond a safe limit shall be transmitted, the rod is connected to the part d through the medium of a thin washer a, which shears when a safe limit of stress is exceeded. Damage to other parts of the machine' is thus avoided, and the washer a is easily renewed. When shearing occurs, the parts are prevented from separating entirely by a chain or cable e.

Title: Manufacture of a Barium Manganate
Inventor: TIXIER AUGUSTE
Filed: 1903-12-29
Granted: 1904-11-03
Abstract: 28,585. Tixier, A., Cambier, R., and Adnet, C. E. Dec. 29. Barium manganate, a dark violet velvety powder insoluble in boiled water and very sensitive to traces of even feeble acids or acid salts, such as carbonic acid and bicarbonates, is obtained by the interaction of the hydroxide or chloride, or other soluble salt of barium, in boiling aqueous solution, with a commercial alkali manganate or permanganate. Barium chloride requires the presence of an excess of alkali, thus :- In a better process, air, free from carbonic acid, is passed over a heated mixture of dry, powdered manganese dioxide'and caustic soda or potash. On adding barium hydroxide, avoiding excess, to the green liquid obtained by lixiviating the mass, the new manganate precipitates. The regenerated alkali can be used again. The manganate is washed free of traces of alkali with water very slightly acidified with a mineral acid until the washings are rose-coloured. Barium manganite, BaMnO3, results from the decomposition at a red heat of the manganate, oxygen being given off. Permanganates may be prepared by the action on barium manganate of sulphuric acid in the presence of a soluble sulphate.
