The @name could be causing some problems. If you really want a  
default of "Nothing", you should move it to the #initialize method.

def initialize
   @name = "Nothing"
end

Try:

class TSPProcess
   attr_accessor :name
end

and in your template:

<% @processes.each do |process| %>
   <tr>
     <td><%= render(:inline => "#{process.name or "Nothing"}")%></td>
   </tr>
<% end %>

You should ruby's convention for file-naming: require 'tsp_process'

You could shorten this to:
class ProcessesController < ApplicationController
   def index
     @processes = [TSPProcess.new]
   end
end
