Title: Vacuum system for gas partic. from vegetable oil deodorising - has roots blower in series with liq. ring pump and separators
Inventor: MATHY CLAUDE
IPC: B01D5/00
Filed: 1982-03-22
Abstract: An industrial plant installation for applying vacuum pressure to a gas of which part is condensable and composed of two liq. phases. One of the liq. phases is water and the other is made up to organic components. The installation is of the type employing at least one Root's blower in series with a liq. ring vacuum pump. Downstream of the liq. ring pump is a first gas/liq. separator which delivers the condensable fraction to a second separator to obtain two liq. phases. Water supplied to the liq. ring pump is precooled in a refrigeration unit. The gas exhausted from the first separator is pref. air. The above vacuum system is pref. associated with an installation for deodorising vegetable oils etc. Used for equivalent capacity in gas treatment, the new installation which successfully employs rotary vacuum machines in place of steam ejectors offers substantial economy in energy usage. The installation is for applying a vacuum pressure to a gas, partic. a gas evolved in deodorising vegetable oils.

Title: Inverter for fluorescent lamp without output transformer - uses power transistors connected in series in bridge configuration and controlled by transformer
Inventor: MERE HENRI EDOUARD COURIER DE
IPC: H02M7/5383
Filed: 1982-06-24
Abstract: The lamp (17) is directly connected as the load in a variation on a four-arm half controlled bridge configuration utilising power transistors (19,20) as the switching element, and capacitors (15,16) as the uncontrolled arms. The DC supply (45,13,14) to the inverter is injected at the top of the bridge and at the mid-point of the capacitor arms (15,16) of the bridge. The power transistors (19,20) are switched by transformer coupling (23) into their base-emitter junction signals from a magnetically coupled blocking oscillator, (29,32) the output of which is dedicated to driving the main transistors (19,20). Another blocking oscillator circuit (46,51,54) is used to convert the DC supply to a high voltage AC supply which is rectified (13,14) to produce the DC rail of the inverter.
