Title: Old paint coat removing - by circulating loosening chemical in vat with spray nozzles
Inventor: MOLNAR GYULA
IPC: B44D3/16
Filed: 1974-08-13
Abstract: Old electrostatic or electrophoretic paint coatings or coatings of powdered plastics, applied electrostatically, are removed by dipping the panels into a vat between two rows of nozzles which spray the loosening chemical against the old coatings. The remnants which drop off are collected a in a strainer basket and the fluid is recycled and kept at a constant concentration. A flushing vat and a drying vat complete the process plant. The chemical action combined with the dynamic action of the jets intensifies the coat removal efficiency. This system requires low capital costs; it reduces the total time required considerably and can be inserted into a production line.

Title: Impulse and doppler switchable radar system - uses appropriate system by automatic switching according to received conditions
Inventor: PACOZZI PIERINO
IPC: G01S13/66
Filed: 1974-09-23
Abstract: The signal reflected from the target may be processed by the receiver either for Doppler shift or for echo-impulse behaviour. The system consists of a transmitter, a receiver and effectively two processing channels. In one of these the transmitter signal phase is established via an intermediate frequency unit and compared with the phase of the received signal. The doppler shift is found from this in a suitable unit. In the other channel the bursts are treated as pulses and are assessed in a suitable unit after amplification in an intermediate frequency strip. The output of one or other of these channels is fed to a computing unit according to the strength of the Dopper channel output. The target may as a result be successfully followed even in paths radial to the position of the radar system, when the Doppler shaft is zero.
