Title: Method for shaping a fibrous reinforcement texture used in the manufacture of a composite material part
Inventor: PATRIGEON YVES D
IPC: C04B41/61
Filed: 1991-03-22
Granted: 1997-12-09
Abstract: ABSTRACT OF THE DISCLOSURE           The  shaping  of the fibrous texture is at  least  partly achieved  by applying a deformable layer or strip, such as a cloth, made  from  a  material  having  a  thermal  expansion  coefficient different  from  that  of  the material  constituting  the  fibrous texture.  The layer or strip is stretched over the fibrous  texture or  is held in position against the texture by being wound over  in order  to  obtain the degree of compaction wanted for  the  fibrous texture. The texture is densified by chemical vapor infiltration of the material constituting the matrix of the composite.

IPC: F28D9/04
Filed: 1991-10-07
Granted: 2003-04-08
Abstract: The ends of numerous tubes are connected to hollow headers so that they are in fluid communication with the headers. Slit shaped apertures are formed in the outside face of the headers in the direction of their circumference, and partitions are inserted through the apertures. Each partition is constructed out of two partition plates which fit into the header through the aperture in their super-imposed position. Alternatively, the partition plates may be connected integral at one end so that their uncon-netted ends tightly contact the edges of the slit shaped aperture. The partitions are then brazed to the header to become integral with it.

Title: Demolition hammer
Inventor: LINDSEY EDGAR F
IPC: B25D17/28
Filed: 1990-09-26
Granted: 1996-09-17
Abstract: A demolition hammer (10) intended for attachment to a backhoe (11) or the like. The demolition hammer (10) includes an adapter bracket (31) which connects to the arm (15) of a backhoe (11) in place of the conventional bucket of the backhoe, and a hammer head (42) spaced apart from the adapter bracket (31) by a hammer spring arm (40) cantilevered or pivotably mounted with respect to the adapter bracket (31). Repeated operation of the backhoe hydraulic cylinder which normally pivots the bucket will instead move the hammer (10) into repetitive impacts with the concrete (77) or other work surface undergoing demolition. The flexibility of the hammer spring (40) adds a whipping action which increases the effective impact of such movement.
