Title: Starter and control increasing hot-cathode fluorescent lamp's life - gradually increases supply over one second to full rating
Inventor: STUEDLI RUDOLF
IPC: H05B41/232
Filed: 1975-01-03
Abstract: The starting and control circuit, for hot-cathode fluorescent lamps, controls switch-on so that it occurs in stages: only after about one second is the full rated voltage applied to the lamp. The switch-on stages are obtained using a relay or an SCR and by delaying the switching of only the ignition transformer. The advantage of staging the switch-on so that the full rated voltage is applied to the lamp only after roughly one second lies in its increasing the lamp's useful life. The centrally installed auxiliary ignition transformer with a protective resistor switched to earth ensures ignition through a capacitative auxiliary ignition winding between illumination body and lamp.

Title: Contact pressure control of contact roller in winding equipment - uses proportional signals initiated by winding diameter to hold contact pressure at optimum value
Inventor: KATAOKA HIROSHI
IPC: B65H23/195
Filed: 1975-09-19
Abstract: The apparatus is used for controlling the contact pressure of a contact roller (1) in an equipment for winding a length of material. An electronics system is used to store formulae for determining a not regulated contact pressure of the contact roller. An optimum roller contact pressure for the winding equipment is also determined by the formulae. The formulae are a function of volume of the wound material or a winding diameter. The winding diameter is continuously initiating proportional signals which are fed in an equipment for calculating the contact pressure from the formulae. The calculated results are then compared and the difference between the calculated results is fed as a proportional electric signal in a mechanical equipment for controlling the contact pressure of the contact roller at an optimum value.

Title: Intermodulation distortion correction for FM radio relay systems - has amplitude to phase conversion with differential amplifier linearisation
Inventor: WEBER HERBERT
IPC: H04B14/00
Filed: 1975-10-22
Abstract: The distortion correction equipment for reducing intermodulation distortion in frequency modulated radio relay systems, uses correcting circuits inserted into the receiver intermediate frequency stages. The distorted IF signal is fed to limiter and all-pass circuit. An amplitude modulation results and the signal is passed to an adjustable converter where it is converted to a phase-modulated signal. The converter circuit uses two differential amplifiers with a PIN-diode in the feedback path acting as a variable linear resistor. The signal is passed through a second all-pass network and the amplitude modulation is suppressed in a further limiter. The output of this limiter produces a corrected, frequency modulated IF.
