Abstract: A method and apparatus for low pressure molding are disclosed. The molding apparatus comprises a frame, a mold assembly and a transmission assembly. The mold assembly may comprise a first mold and a second mold, the second mold being coupled to the frame. The transmission assembly may be coupled to the frame and to the first mold. A motor may be coupled to the transmission assembly for moving the first mold relative to the second mold. A pneumatic actuator may also be coupled to the transmission assembly for increasing clamping pressure between the first mold and the second mold.

Abstract: To provide a transportable cooling unit for maintaining a transport volume at a defined temperature, comprising a closed cooling circuit and a controller sensing a temperature present within said transport volume and controlling said cooling circuit so as to provide the cooling power demanded at said evaporator for maintaining said defined temperature and minimizing energy consumption, said controller operates said closed cooling circuit between a minimum possible cooling power and a maximum possible cooling power in a sequence of different operational stages, said controller further operates said closed cooling circuit in each one of at least two upper operational stages at a compressor speed related cooling capacity different said other upper operational stages and within said respective upper operational stages said controller operates a compressor in an uninterrupted mode and adjusts said cooling power stepless speed control of said compressor.
