A redaction process (10) to enable a user to redact an electronic document on a computer. The redaction process (10) includes the steps of converting a copy of the original electronic document file (14) from its native format into the format of an electronic image file. The user may redact sections of the electronic image file, and save the redacted electronic image file in electronic file format.

Disclosed is a self-cleansing intrusion tolerance-domain name systems system comprising at least three DNS servers, at least four storage systems accessible by the DNS servers, a communications link, a message transfer mechanism, and a self-cleansing mechanism. The storage systems include at least three online storage systems and at least one offline storage system. The communications link can connect the DNS servers with the storage systems, as well as connect the DNS servers with a local area network, which can connect the DNS servers with an external network. The message transfer mechanism can rotate the DNS servers into a plurality of roles, including a primary role, a secondary role, a designated role, and a self-cleansing role. The self-cleansing mechanism can be used to perform the self-cleansing role.

An apparatus and method for the production of nanotubes, fullerene and their derivatives where, in an environment where an inert gas flows at or below atmospheric pressure, a high frequency electromagnetic field is generated and a pure or doped graphite element is subjected to the electromagnetic field and heated to vaporization to form a plasma.

A dye composition of 99.7% pure glycerin and press cake dye is provided along with an apparatus and method of use for the same. The apparatus sets the dye composition into polyester yarns by heating the composition to 160-190° C. and then cooling the composition to 100-140° C. Prescour, dye scour and post scour vessels are provided to facilitate the dyeing process. The fluids used in the apparatus and process are recycled by recycling units.

The invention discloses a thermal bulging process for flash-welded stainless steel ring workpieces, which includes steps of primary bulging; primary rotation; secondary rotation; secondary bulging and tertiary bulging. In the primary bulging, a flash-welded stainless steel ring workpiece which is annealed is sleeved on the periphery of a preheated bulging block in a bulging machine after being heated, and the bulging block squeezes the ring workpiece axially along the inner circumference of the ring workpiece after the bulging machine is started so that the primary bulging is completed, wherein the bulging temperature ranges from 950 DEG C to 1040 DEG C, the bulging time ranges from 22s to 28s, the pressure holding time ranges from 18s to 20s, and the bulging deflection ranges from 0.12% to 0.15%. The primary rotation is completed by rotating the ring workpiece along the center axis by 45 degrees. The secondary bulging is completed by processes of the primary bulging, wherein the bulging temperature ranges from 920 DEG C to 1010 DEG C, the bulging time ranges from 20s to 25s, the pressure holding time ranges from 16s to 18s, and the deflection ranges from 0.08% to 0.09%. The second rotation is completed by rotating the ring workpiece again along the direction the same with that of the primary rotation. The tertiary bulging is completed by the processes of the primary bulging again, wherein the bulging temperature ranges from 890 DEG C to 980 DEG C, the bulging time ranges from 25s to 30s, the pressure holding time ranges from 21s to 23s, and the deflection ranges from 0.09% to 1%. The dimensional precision of the ring workpiece can be 1%. to 2%. of the corresponding precision after the ring workpiece is bulged, and the ring workpiece is mainly used for the field of space navigation.
