Title: Automatic fabric-guiding device for calender machine input - has photoelectric detector controlling swivelling guide plate with convex edge
Inventor: STICHNOTH ANDREAS
IPC: D06F67/04
Filed: 1979-10-10

Title: Measuring frequency of pulse series by summation - using defined time increments and comparison with summation limit value
Inventor: GROENING DIETER-ECKARD
IPC: G01R23/10
Filed: 1979-10-15
Abstract: The system measures the frequency of a pulse series by counting the number of pulses occurring in a given time operation independently of periodic components in the pulse series. The device has a rapid response and a short integration time. It produces a digital output signal suitable for electronic data processing. The pulses are summed to form primary summed values at successive time intervals. The primary values are summed to form secondary summed values. The time intervals are chosen such that the number of pulses occurring in each does not exceed a given number. When the secondary summation exceeds the pulse limit by one, the corresp. first summation is reset to unity and the achieved value is output.

Title: Cup deep drawing sterilisation and filling - combining preheating of foil with prior sterilisation
Inventor: WALTER KURT ING GRAD
IPC: B65B55/10
Filed: 1980-08-22
Abstract: The Parent Patent (3016169) described a method for the mfr., sterilisation and filling of containers, esp. cups for yoghurt, cream and other milk prods., in a continuous flow line. The phase during which the foil is prepd. for the deep drawing operation by preheating is now also carried out with a sterilising medium e.g. steam. The heating surfaces of the preheating station are equipped with shallow recesses and control inlets for the supply of a sterilising hot medium. This heats and sterilises the foil as it moves in steps to the deep drawing station where the cups are produced. This optimises the total effect of the sterilisation and ensures freedom from all germs.
