alignment with opening 103 to a position in alignment with a
window 109 (see Figure 1). When the label is deposited on the
transport 105, it is held in place by a low vacuum carrier,
applied to the label through the carrier. When the label is

transport 105 is moved upwardly by an air cylinder (not shown

slot 48 and affixed to an end wall 50 from which they can be
removed by an operator and packaged for return to the
customer.
In our view, the suggestion for modifying the applied

from the combined teachings of the applied prior art but stems
from hindsight knowledge derived from the appellants' own
