Patent DE-2531442-A1 (DE)
Inventor: MILICEVIC BRANIMIR DR
IPC: D06B23/28
Filed: 1975-07-14
Abstract: The process permits the process course when dyeing or optically brightening textile material according to the exhaust method, - e.g. with respect to the quality of the dyeing or the brightening effect and/or to the minimisation of the expenditure of time, energy or auxiliary chemicals to be consumed -, to be conducted optimally. For the determination of the concentration change of the dyestuffs or optical brighteners in the dyestuff or optical brightener single- or multi-component system employed, this system is considered on the basis of the empirical values in the immediate past using a model in order to determine the optimal control parameters which are used as discrete operating or control values for the self-adjusting direct digital control of the course of the process. Using this process, the course of the process when dyeing using dyestuffs or brighteners which in solution do not obey Lambert-Beer's law can be optimally conducted.

Title: Cage and meshing cam rotary piston machines - are used as compressors with charge cooling included in cycle
IPC: F04C29/04
Filed: 1975-10-02
Abstract: The cage- and meshing cam-rotor type rotary piston compressor, has the air cooling fins (12) on that part of the casing where, due to the meshing of the cam rotor (7) with the cage rotor (6), compression takes place. The fins are hollow, the holes being drilled from inside the casing to form closed pockets into which gas from the working chamber (9) flows as the rotor turn. Further rotation of the rotors results in the pockets being temporarily sealed by a cage bar (10), trapping the gas in them and allowing it to lose heat through the fin walls. When the pockets are subsequently opened to the next-in-line working chamber the gas at higher press. than that in the chamber escapes and mixes with the gas in the chamber. Fresh hot gas replaces it, re-starting the cooling cycle.
