Title: Electric surgical scalpel with HF current source - has active and return electrodes, generator and capacitive impedance monitor
Inventor: VASSY RENE
IPC: A61B18/16
Filed: 1981-11-20
Abstract: The appts. has an active electrode (A) which is a scalpel and a return electrode in the form of two plates (P1,P2) placed between the patient (P) and the operating table (B). The plates (P1,P2) are covered in an insulating dielectric film (D1,D2) and are connected by two leads (11,12) to a mixer (T) which is a transformer. A high frequency generator (G) is connected by a lead (10) to the active electrode and by another lead (13) to the transformer. A capacitive impedance measuring device (M) is also connected to the transformer by two further leads (14,15). The capacitive impedance measurement represents the state of the high frequency return signal and is therefore an indication of a good contact between the plates and the patient's skin. The appts. eliminates the risk of electrocution and burning.

Patent FR-2524909-A1 (FR)
Title: Ultrasonic degreasing of machined parts - with continuous recycling of filtered and settled fluid
Inventor: GUIGON JEAN-PAUL
IPC: B08B3/12
Filed: 1982-04-08
Abstract: Machined metal parts are degreased by immersion in a tank of fluid, with ultrasonic agitation. The carrier for the parts, and the ultrasonic generators are displaceable relative to each other. Dirty fluid is pumped through a filter and a number of settling tanks in series, and recycled into the tank. The tank is pref. circular, with the carrier moving vertically and in rotation about a central axis. The ultrasonic generators are on a fixed horizontal support, forming a sector of the circle. Fluid is returned through a spray bar, set radially above the tank, pref. on the inside of a hinged lid. By rotating the parts, the whole of the surface of large units can be swept efficiently, by a limited number of ultrasonic generators, ensuring complete degreasing. Raising the support above the fluid allows the part to be rinsed after degreasing. Continuous filtering and settling out of residues from the fluid, allows efficient use of the tank. For compactness the settling tanks may be arranged circumferentially around the cleansing tank.
