Title: Confectionery decorating machine - with same motor driving nozzle in two perpendicular directions by crank and cam drive
Inventor: SOLLICH HELMUT
IPC: A23G3/28
Filed: 1977-06-03
Abstract: Machine has a drive motor which moves a coating nozzle at right angles to the movement of the belt conveyor with the confectionery.

Title: Generator for fluorescent lamp with variable impedance characteristic - has transistor, coil and capacitor affecting internal impedance at start and on load
Inventor: SHERMAN ELI H
IPC: H02M7/537
Filed: 1979-06-11
Abstract: The generator is for driving electrical loads with variable impedance characteristics, such as ion conduction lamps which have a relatively high ignition or starting impedance and a considerably lower operating impedance. The power supply to the lamp is proportional to the impedance and this causes considerable energy saving. The internal impedance of the generator incorporates a transistor and a coil (42, 46) to make is comparable with the load impedance during the starting process. A capacitive component cones into operation when the impedance of the load changes so that the internal impedance of the generator will become comparable. The starting voltage across the load is relatively high and is effectively switched off during the running operation.
