20120240755 | BALLISTIC APPLICATIONS OF COMPOSITE MATERIALS - A composite ballistic armor or other composite component may be formed by placing one or more ceramic cores in a mold and introducing molten base metal into the mold, such that the molten base metal encapsulates the one or more ceramic cores to form the composite component. The ceramic cores may comprise, for example, porous packed-particle ceramic cores or pre-cast porous ceramic cores. The base metal may comprise, for example, a steel alloy, such as FeMnAl. | 09-27-2012 |
20120244341 | COMPOSITE COMPONENTS FORMED WITH LOOSE CERAMIC MATERIAL - An apparatus and methods for controlling the location and distribution of loose ceramic particles in a ceramic metal composite component formed via casting. A retaining structure that may include loose ceramic particles is placed in a casting mold at a desired location for ceramic particles in the composite component prior to pouring molten metal into the casting mold. Alternatively, the loose ceramic particles may be introduced into the mold concurrently with the molten metal. | 09-27-2012 |
20120244344 | COMPOSITE COMPONENTS FORMED BY COATING A MOLD WITH CERAMIC MATERIAL - Methods and processes are described that form ceramic wear surfaces on the outer surface of a cast part. A mold having a mold cavity is provided. The mold cavity may be washed using a refractory wash to provide for a smoother finish to the surface of the cast part and to maintain mold integrity. An adhesive is applied to predetermined locations in which increased wear during the use of the cast parts is anticipated to occur. Ceramic material may be applied to the predetermined locations by various means. A mask may be used to remove excess material from areas other than the predetermined locations. A molten metal is poured into the mold cavity and allowed to cool to form a cast part with a ceramic wear surface. | 09-27-2012 |
20130025440 | Encapsulated Solid Ceramic Element - A composite ballistic armor or other composite component may be formed by encapsulating one or more ceramic elements in a casting shell and introducing molten base metal into the casting shell, such that the molten base metal encapsulates the one or more ceramic elements to form the composite component. Prior to the pouring process, the ceramic elements are pre-heated to, or near, the melting point temperature or pouring temperature of the encapsulating metal. Additionally, the cooling rate following the metal pour may be less than a predetermined rate for a predetermined period of time. The encapsulating metal may comprise, for example, a steel alloy, such as 4140 or 8630 AISI, a stainless steel alloy, or FeMnAl. | 01-31-2013 |
20130284005 | SEAM PROTECTED ENCAPSULATED ARRAY - Seam protected encapsulated arrays of solid ceramic elements are disclosed. Vulnerable seams between solid ceramic elements arranged adjacent to each other in encapsulated arrays of solid ceramic elements are protected by a seam protector arranged in-line with the vulnerable seems and fixed to the encapsulated array. A stiffener may be arranged in-line with the vulnerable seems and fixed to the encapsulated array opposite to the seam protector. The solid ceramic elements may be encapsulated in a barrier material to prevent the base metal from reacting with the ceramic material units during casting, and/or provide crush/compression protection during cooling. | 10-31-2013 |
20130287988 | ENCAPSULATED ARRAYS WITH BARRIER LAYER COVERED TILES - Encapsulated arrays with tiles covered with a barrier layer are disclosed. Tiles formed of silicon carbide, and wrapped with a barrier layer, are encapsulated with a base metal formed of a steel alloy. During a casting process, to fabricate the encapsulated arrays, the barrier layer prevents the steel alloy and/or the silicon carbide from compromising each other. | 10-31-2013 |
20140033908 | Encapsulated Preformed Shapes - Anti-ballistic component including encapsulated preformed ceramic shapes are disclosed. Preformed ceramic shapes having a preformed geometry are encapsulated in a metal alloy to stiffen and lighten an anti-ballistic component. The preformed ceramic shapes may be arranged in layers of uniform arrays of preformed ceramic shapes and contained in a porous container to receive the metal alloy during a casting process. A truss structure may be integrated in the preformed ceramic shapes to compartmentalize the preformed ceramic shapes into multiple isolated sub regions to stiffen the anti-ballistic component. | 02-06-2014 |
20140037871 | Encapsulated Preformed Shapes - Composite wear parts including encapsulated preformed ceramic shapes are disclosed. Preformed ceramic shapes are embedded in a metal alloy to protect the base metal from abrasion. The preformed ceramic shapes may have a uniform, preformed geometry that provides for packing the preformed ceramic shapes together in a uniform way. The preformed ceramic shapes may be positioned at a location in the composite wear part exposed to an abrasion without using a binding agent. The preformed ceramic shapes may also be contained in a porous container. A truss structure may be integrated in the preformed ceramic shapes to compartmentalize the preformed ceramic shapes into multiple isolated sub regions to stiffen the composite wear parts. | 02-06-2014 |

20150100662 | UTILIZING MULTIPLE DATA STRUCTURES FOR SLICE STORAGE - A method includes a dispersed storage (DS) processing module receiving a slice access request that includes a slice name. The method continues by obtaining one or more revision numbers for the slice access request. The method continues for each combination of revision number and the slice name, by performing a deterministic function on the combination to produce a slice location table index value. The method continues by accessing a slice location table utilizing the slice location table index value to obtain a slice location. The method continues by accessing a slice utilizing the slice location. The method continues by generating a slice access response based on the accessing of the slice and sending the slice access response to a requesting entity. | 04-09-2015 |
20150100697 | SESSION EXECUTION DECISION - A method includes a dispersed storage (DS) processing module receiving a request. The method continues by identifying a session associated with the request. The method continues by queueing one or more tasks associated with the request. The method continues by determining whether the session is still active. When the session is not active, the method continues by cancelling the one or more tasks associated with the session prior to execution. When the session is still active, the method continues by executing the first task of the one or more tasks when a task resource is available. | 04-09-2015 |
20150100727 | MIGRATION OF ENCODED DATA SLICES IN A DISPERSED STORAGE NETWORK - A method includes a processing module of a storage unit of a dispersed storage network (DSN) monitoring input/output (IO) rates of a plurality of disk drives, where access requests for encoded data slices occur at varying rates. The method continues with the processing module determining that the IO rate of a disk drive is exceeding a desired maximum IO rate and identifying a pending access request for an encoded data slice stored in the disk drive. The method continues with the processing module evaluating disk drive processing rates of other storage units that are storing other encoded data slices of a set of encoded data slices that includes the encoded data slice to determine whether the encoded data slice is needed to satisfy the pending access request. When the encoded data slice is needed, the method continues with the processing module migrating the encoded data slice to another disk drive. | 04-09-2015 |
