Abstract: This invention relates to a porous nickelide of titanium (TiNi) material also comprising oxygen, that is biomechanically and biochemically compatible and is intended primarily for use in the biomedical fields for implantation and interfacing with living tissues. The material has a porous structure defined by morphological, mechanical and surface properties to conform well to adjacent bone to which the TiNi material is designed to bind. The material is further distinguished by a complete lack of nickel enriched secondary phases. These phases may leach nickel into the body which could result in complications associated with nickel toxicity. The mechanical properties and surface characteristics achieved confirm the biofunctionality of the invention.

Abstract: A process for preparing a sintered article of a compacted iron-based metallurgical powder. The green compact is sintered at a closely held predetermined temperature in order to achieve desired density and dimensional stability.

Abstract: An electrically insulated support or the like is mounted on a helicopter to extend from both sides of the helicopter. A bucket for equipment, material and/or a worker is provided, which can be engaged or disengaged at the end of the support. To carry out operation on a high voltage line or installations, the bucket with its equipment, material and/or worker is hooked at one end of the support and is carried by the helicopter to a location of the high voltage line or installations where an operation has to be carried out. The operation is done while the helicopter holds the bucket or most preferably, the bucket which is provided with suspension wheels is mounted on the line conductors or installations and the helicopter is moved away while the operation is being carried out.
