    • A self-sintered silicon carbide/carbon-graphite composite material having interconnected pores which may be impregnated, and a raw batch and process for producing the composite material, is provided. The composite material comprises a densified, self-sintered matrix of silicon carbide, carbon-graphite inclusions and small amounts of any residual sintering aids, such as boron and free carbon, and has interconnected pores which may be impregnated with resin, carbon, TEFLONTM, metal or other compounds or materials selected for their particular properties to achieve desired tribological characteristics for a specific application. The composite material is produced from a raw batch which includes silicon carbide, sintering aids, a temporary filler and coated graphite particles. The raw batch is then molded/shaped into a green body and heated to carbonize any carbonizable materials and to decompose and volatilize the organic filler to form a matrix of interconnected pores. The green body is pressureless sintered to densify the matrix. The interconnected pores may then be impregnated with a resin, carbon, metal, TEFLONTM, compound or other material selected for desired tribological characteristics.
    • 提供了一种具有可以浸渍的互连孔的自烧结碳化硅/碳 - 石墨复合材料,以及用于生产该复合材料的原料批料和方法。 该复合材料包括碳化硅致密自烧结基质,碳 - 石墨夹杂物和少量任何残留的烧结助剂,例如硼和自由碳,并且具有可以用树脂,碳,TEFLON TM, 金属或其他化合物或材料,以针对它们的特定性质进行选择以达到用于特定应用的所需摩擦学特性。 该复合材料由包括碳化硅,烧结助剂,临时填料和涂覆石墨颗粒的原料批生产。 然后将原料模塑/成形为生坯并加热以碳化任何可碳化的材料并分解和挥发有机填料以形成互连孔的基质。 生坯被无压烧结以使基体致密化。 然后可以用树脂,碳,金属,TEFLON TM,化合物或为了所需摩擦学特性选择的其他材料来浸渍互连孔。

    • A system for deploying life rafts from ships, wherein the life rafts (2, 3) are of the inflatable type and where there are stocking-like bodies (7) for transfer of personnel from the ship to at least one of the life rafts. The life rafts are arranged in groups which are loosely connected with a common bottom frame (1), and where each group comprises a reception raft (2) and several evacuation rafts (3) detachably connected with the reception raft (2). The said bottom frame (1) is suspended from at least one winch wire (4) arranged from a support frame (5) which can be moved from a parked position inside the ship's side to an operative position outside the ship's side. When the support frame (5) is in an operative position, the bottom frame (1) can be lowered into the water by means of the winch (8). The winch wires (4) pass through sliding guides (6a) in the bottom of the reception raft and sliding guides (6b) in a known per se rescue stocking (7) which is stretched between the support frame (5) and the reception raft (2). The reception raft is automatically inflated when the bottom frame (1) is lowered below the surface of the water, while at the same time the evacuation rafts (3) remain afloat uninflated beside the reception raft (2) and detachably connected with it. The evacuation rafts' inflation mechanism can be actuated manually from the reception raft as required, thus maintaining a continuous, safe escape route from the ship's deck to the evacuation rafts.
