rigid bond with each other via a binding means. The binding
means is resistant to hydrocarbons so as to allow the mat body
to maintain its overall shape not withstanding contact with
the hydrocarbons. Moreover, the granulates or shavings are
joined in a fashion such that a multiplicity of hollow spaces
that communicate with each other are formed in the body.
Additional spaces are also formed in the body to provide for
swelling as hydrocarbons are taken in by the body. The body
has an uncovered top surface for receiving hydrocarbons.
According to appellant, the mat may be "... placed on floors,
ramps and service aisles..." (specification, page 2) to
protect the environment from hydrocarbons that may drip by

or solid form including oils, fats, fuels and solvents, the
absorption mat comprising:
a flat molded body having a plate or block configuration;
said body having an uncovered top surface completely
exposed to receive said hydrocarbons thereon;
said body being defined by granulate or shavings made of
elastomer for absorbing and trapping said hydrocarbons
therein;
