  • Insertion compounds based on manganese oxide usable as the positive electrode active material in a lithium battery
    Patent number: 5700442
    Abstract: The invention relates to the preparation of insertion compounds based on manganese oxide, usable as the positive electrode active material in a lithium battery.These compounds in the hatched area of FIG. 1 can be prepared by reacting in the solid state a manganese oxide powder MnO.sub.2 -.beta., having a specific surface below 7 m.sup.2 /g and an average grain size below 10 .mu.m, with a powder of a lithium compound such as Li.sub.2 CO.sub.3 or LiOH, at a temperature of 150.degree. to 500.degree. C. for an adequate time to convert the .beta.-MnO.sub.2 into manganese and lithium oxide having a lacunary or stoichiometric spinel structure.

  • Device for interlocking together two adjacent metal frames from two different levels
    Patent number: 4563849
    Abstract: There is described a device for interlocking together two adjacent metal frames from two different levels in a "glass skin", fitted on the framework of a building, whereon said frames are mounted either rigidly or flexibly, the components of said device having to be mounted on two frame sections which are horizontally adjacent in mounting position, which is comprised on the one hand of a male part integral with a section from the one frame, and on the other hand of a female part integral with a section from an adjacent frame which is mounted in use position, in an adjacent level, the female part having a lengthwise recess extending in mounting position, in parallel relationship with the general plane of the frame under consideration, in such a way that under the action of a translation movement of the one frame relative to another one, made in that general plane both said frames lie in, the male part is free to perform a translation and/or rotating movement relative to the female part, while both adjacent fra

  • Curtain wall structure
    Patent number: 4073107
    Abstract: There is described a curtain wall structure comprising a metal frame provided with a compensation bar for bearing on or hanging from a projecting element fastened to the building skeleton, each metal frame also comprising members for taking over the forces due to the wind, in which said projecting element is provided with resilient means on which said compensation bar bears.

  • Curtain wall structure
    Patent number: 3994107
    Abstract: There is described a curtain wall structure in which each glazed element is supported in one point by a compensation bar which is part of the glazed element, which bears on or hangs from a swivel joint projecting from the building skeleton, said element being further retained by members for taking over the forces due to the wind.
