Title: Appts. for regeneration of engineering oil - has dispersion tower between inlet sub-assembly and degassing sub-assembly
Inventor: PLEVNIK JANEZ
IPC: C10M175/00
Filed: 1989-10-23
Abstract: This is an arrangement for the regeneration  of engineering oils, and in particular for separating water from the oil by evaporation of the water under a reduced pressure and removing the  condensate. A dispersion tower is incorporated between an inlet sub-assembly and a degassing subassembly.  The inlet one contains a preliminary filter, a heater and a fine filter, and the outlet one consists of a cooler, a condensate collector and a vacuum pump. Installed in the top part of the tower are a dispersion head and, below it and connected to it, a parabolic deflector. Variants claimed include the providsion of dispersion jets in the bottom of the dispersion head. USE/ADVANTAGE - This oil reclamation arrangement can handle high-viscosity oils and provides cool oil of high kinematic viscosity without the use of the very large filter-areas required elsewhere.

Title: Cigarette lighter for motor vehicle - has incandescent device pushed towards by cigarette to operate switch applying voltage to electrical heating resistance
Inventor: PRIESEMUTH WOLFGANG DIPL ING
IPC: B60Q3/02
Filed: 1990-01-03
Abstract: The cigarette lighter has an electrical resistance that glows red hot when a voltage is applied and forms part of an incandescent dervice (12).
