Trousers andor shorts are fed one at a time between conveyor belts, cuff end first, towards a hanger automatically dropped from a hanger bar into a hanger chute positioned in the path of travel of the trousers. The number of full partitions written to external memory may be increased by temporarily storing packets using on-chip memory that is on a chip with the processor. Input data is periodically received or intermediate or output data is generated for one or more of the processing paths of the workflow, via one or more operators, based on a scheduler process. the input, or output, or the combination of both, to control the refrigerant flow through the evaporator in a manner to improve the performance of the system. The invention further concerns light weight objects obtainable by the process.
