Patent no. RO123479 / 28.09.2012
The invention relates to a pneumatic ejector used in the
construction of plastic injection molds for removing the auto
parts mold. The pneumatic ejector described here, uses dual
action pneumatic cylinders which are made in standardized

cylinders are designed in such way that the two chambers
have no special requirements regarding the connecting pipes
or seals. The air is acting on the piston through a network of
holes in the mold body.

Ultra-High Performance Concrete represents a technical
solution for structures due to concrete ultra-high
compression resistance, high durability and ductility, which
conduct to smaller cross-sections, greater spans and lower
costs for erection and maintenance. Furthermore, the
concrete technology enables rapid casting due to concrete
good workability and great strengths at early ages (if subject
to thermal treatment).
The invention refers to an Ultra-High Performance Concrete
(UHPC) with compression strength of 180+10 MPa suited
for building structures, road and bridges structures, railways
sleepers, containment buildings for nuclear reactors, marine
