Title: Mixed fiber composite structures: method of preparation, articles therefrom and uses therefor
Inventor: TATARCHUK BRUCE J
IPC: D04H1/42
Filed: 1990-05-24
Abstract: A family of composites are characterized as a network of a first fiber and at least a second fiber, where at least the first fib-ers have a multiplicity of bonded junctions at their point of crossing. The largest class has metals as one or both of the fibers, al-though the second fiber can be of materials such as carbon, ceramics, and high surface area materials.

Patent CA-2065832-A1 (CA)
Inventor: MATSUMOTO TOSHIO
IPC: G11C29/00
Filed: 1992-04-10
Abstract: A recording device which improves a response time to write data by reporting to a host computer the completion of writing operation prior to the completion of writing redundancy data. Data writing command information from the host computer is stored in a command/status memory backed up by a power source in an array controller, and the completion of writing operation is reported to the host computer at the time of the completion of writing updated data prior to the completion of writing redundancy data. Redundancy data is written as a background process. If redundancy data could not be written due to any abnormality of the power source or the like, such redundancy data may be generated from the data in other disk units of the same redundancy group in accordance with writing command information stored in the command/status memory, thereby completing the writing of redundancy data.

Title: Process for concrete building construction
Inventor: PICA ANTONIO
IPC: E04B5/36
Filed: 1992-05-12
Abstract: ABSTRACT         A method of constructing a floor structure into a building such that a unitary building structure is formed, is disclosed.  The floor structure comprises rows of flooring slab members supported by first and second supporting structures at the ends of the pre-poured concrete flooring slab members.  The flooring slab members have a main body portion and a steel reinforcing means positioned within the main body portion so as to structurally reinforce the main body portion.  The flooring slab members further have a lift receiving means integrally retained within the main body portion for secured releasable engagement by a suitable lifting means such as a crane or derrick.  The flooring slab members are put in place adjacent one to another in laterally substantially abutting relation to form the rows of flooring slab members, and are placed properly by the lifting means without subsequent adjustment necessary. After the flooring slab members are in place, a second steel reinforcing means is placed thereabove, spaced above the top surface of the flooring slab members.  An extension bulk head is erected around the perimeter of the floor structure and a concrete top layer is then poured onto the rows of flooring slab members.  The concrete also is poured into voids in the supporting structures thus forming a unitary building structure comprising the combination of the poured concrete top layer, the second steel reinforcing means, the pre-poured concrete flooring slab members and the first and second supporting structures.

A shuttle pole-piece for boosting available energy extends upwardly into the winding opening and is movably mounted with a resilient upward bias for permitting the shuttle pole-piece to move downwardly for reducing impact shock, noise and vibration upon being struck by the downwardly-moving armature upon completion of its work stroke. There are anti-skid supports for the ball bearings and ball cages of the ball-bearing bushings which carry the movable tool for preventing downward skidding of these balls and their cages when the moving tool punches down against the work material. Adjustable resilient cushioning arrests tool travel for minimizing "tool whip" and tool wear at the end of the work stroke.
