A process and composition for the beneficial utilization of waste materials which contain energetic materials are disclosed. Predetermined quantities of the waste material containing energetic materials are placed in admixture with commercial blasting agents causing the energetic materials to participate in the detonation process thereby utilizing energetic materials which would otherwise enter the waste stream. The waste material, in particulate form, that contains the energetic material is introduced into the blasting agent when the latter is in a relatively fluid state. The modified blasting agent is suitable for use in the normal manner such as in bulk or packaged form.

Beneficial use of energy-containing wastes

A process and composition for the beneficial utilization of waste materials which contain energetic materials are disclosed.

The present invention discloses a method for safely and easily shredding a variety of material particularly material having a low melt temperature and/or containing material sensitive to high static electric charges, such as 1.1 and 1.3 class material. The method comprises applying a cloud of gas vapor onto the shredding means to cool the shredding means to a temperature below that of the melt temperature of the material being shredded and to also reduce the static electric charge on the resulting particles of material which may develop during the shredding process. Further described is an apparatus for carrying out the method.

Method for shredding material

Fabrication of magnetic recording media having a coating containing harsh pigment like CrO.sub.2 particles and adapted for frequent contact with a head, with good durability, abrasivity, etc., accommodated by using a lubricant system including a fluoro-silicone oil and a compatible fatty-acid-ester like butoxy ethyl stearate.

Fabrication of magnetic recording medium with lubricant

Described are devices for securing a computer tape reel to an associated surrounding 'wrap' where a T-sponge is inserted as an 'inertial brake/hold down' between reel and wrap.

'Brake/hold down' plug for computer tape reel closure

A novel resinous binder composition is disclosed for a magnetic recording tape or like media. Magnetic particles are dispersed within a resinous matrix having both a 'hard' and a 'soft' component. The 'hard' component is fabricated by exposing a resin capable of being cured by electron beam irradiation. The magnetic recording media coating is very apt for use with harsh pigment like CrO.sub.2 particles and is adapted for frequent contact with a head, being adapted to exhibit good durability, abrasivity, etc. by virtue of using a lubricant system including a fluoro-silicone oil and a compatible fatty-acid-ester like butoxy ethyl stearate.
