Patent FR-2519510-A1 (FR)
Title: Air leakage tester for electronic component encapsulations - has electrode on either side of component wall establishing 20 KHz AC at voltage above ionisation but below breakdown levels
Inventor: FLEURET DANIEL
IPC: H01L21/00
Filed: 1981-12-31
Abstract: In an automated production line a wheel with arms picks units from a conveyor belt and rotates them to a test head under the control of a stepping motor. A high voltage generator (9) connects a 20kHz signal at voltage between 10 and 30 Kilovolts to the test head. The end of the arm carrying the housing is at earth potential. The voltage is sufficient to cause ionisation of the air but does not cause breakdown of the insulation material. Any small hole in the housing, which would give rise to leakage of insulation filter material, allows a current to pass between the electrodes. When a current flows, it is detected by a transformer secondary connected across the electrodes and a signal is sent to a comparator circuit.

Title: Dough and pastry rolling mill
Inventor: PRADILLON RAYMOND
IPC: A21C3/02
Filed: 1984-02-23
Abstract: Dough and pastry rolling mill comprising, on both sides of the rollers of the mill, two conveyor belts designed to feed alternately in and out the dough or pastry to be rolled. Between the shaft 3 of the roller 1 and the axles 6a and 6b of the driving drums of the two conveyor belts, there is a coupling system comprising two idle wheels 10a, 10b running in opposite directions in order each time to drive only that axle of the drum located on the outgoing side. Moreover a link exists between the axles 6a, 6b of the two drums 5a, 5b in the form of a belt 11 engaged around two pulleys 12a, 12b carried by these axles. This belt is normally slack but, by means of a control system, an adjustable pressure can be exerted on this belt 11 so as to drive at a variable speed the drum located on the incoming side, the axle of which is thus disengaged from the shaft 3 of the mill roller 1. Although possessing a single drive motor, the present apparatus makes it possible to vary the speed of the conveyor belt operating as the feed belt.
