Title: Automatic stoning and pip removal process for fruit - using a rotating scoop moving with the halved fruit
Inventor: DUVAL PIERRE
IPC: A23N4/04
Filed: 1975-07-08
Abstract: Automatic stoning and pip-removing process for fruits (e.g. peaches, guavas, melons etc.) comprises introducing a scoop between the two halves of the fruit and turning this around its own axis whilst accompanying the fruit moving on the conveyor. The graded fruit arrives by the chute and is seized by two parallel conveyors which carry cups; the fruit meets the knife and is cut into two halves which are carried forward opposite each other with a space between. The scoops, mounted on two chains, are introduced into this space, rotated by a rack and pinion and then withdrawn. The pips and stones are evacuated through the slot assisted by a stream of water. The stoned fruit halves, with the cut faces downwards, are carried by the conveyor beneath soda sprays which remove the skin. The process can be adapted for fruits of different sizes by altering the spacing of the two parallel conveyors and of the guides.

Title: Device for measuring the conductivity of liquids - which compensates fully for secondary electrode phenomena with accurately adjustable cell constants
Inventor: BRENET JEAN PAUL
IPC: G01N27/07
Filed: 1976-08-20
Abstract: A device for measuring the conductivity of liquids, to be used with an alternating current bridge, has two cells inserted in two adjacent branches of the bridge. The cells are filled with a measured amount of liquid and each defines a distinct cell constant between two electrodes. Each of the cells, immersed together in the liquid to be measured contained in a vessel, is limited, laterally by a tubular insulating wall with ends cut at right angles. At a first end, the cells are limited by a first electrode arranged at right angles inside the tubular wall and closing it, whilst at its second end, there is a second flat electrode with the same surface as the first, aligned coaxially with it and placed on a flat insulating support, a short distance from the end of the tube. The two tubular walls have the same internal diameter, but the distances between the first and second electrodes are different for each cell. The two tubular walls are located vertically above a support for the second electrode which is common to both cells, and the two electrodes are connected electrically to a point on the bridge between the two branches. The constants of the two cells can be determined directly from their geometrical dimensions. The tensions due to secondary phenomena on the electrodes are compensated exactly. The constants of the cells can be adjusted accurately.
