Patent DE-2618814-A1 (DE)
Title: AM sideband signal unwanted frequency reduction - divides carrier frequency, filters carrier out and multiplies it by same factor to regain original frequency
Inventor: KAHN LEONARD RICHARD
IPC: H04B1/10
Filed: 1976-04-29
Abstract: The AM signal carrier is filtered out and divided by a divisor greater than one. Carrier so divided is filtered out for reduction of interfering and adjacent frequencies. The carrier is now multiplied by the same factor in order to recover its original frequency. The received carrier is demodulated with the divided, filtered and restored carrier. The carrier is precisely determined once it has been filtered to remove any interference from the amplitude modulated signal.

Title: Slot punching press for stator or rotor laminations - has computer circuit operated gauge using stack height to determine lamination dia.
Inventor: SCHNEIDER FRANZ
IPC: H02K15/02
Filed: 1976-07-10
Abstract: The dias. of the first and the last of the rotor and/or stator lamination, the nominal lamination thickness and the stack height are fed into a computer circuit to determine the cone angle required for the stack. The installation incorporates a gauge for measuring the thickness of the laminations which are fed to the press. The output from this gauge is processed in one stage and fed to the computer circuit. The output of the computer circuit represents steps for the electronically controlled adjusting mechanism which alters the distance of the punches to the laminations. The arrangement includes at least one stacking station with stack height measuring gauge. This gauge determines the difference between the actual stack height and the required stack height.

Title: Fluorescent tube operated from DC source - has cataphoretic compensation using condensed mercury at top of tube returning to anode pool
Inventor: GOEPFERT JOACHIM DIPL ING
IPC: H01J61/72
Filed: 1976-07-30
Abstract: A fluorescent tube (1) is operated on DC and has cataphoretic compensation. The fluorescent tubes (1) are pref. installed vertically or at an incline to the vertical.
