Title: Retarding device with fluid control
Inventor: JOLY JEAN-LOUIS
IPC: F15B21/10
Filed: 1987-08-19
Abstract: To control the change of state of a system such as a valve R sited between two sets of pipework, a retarding device is used controlled by the injection of a fluid under pressure into a control chamber 40. This injection has the effect of displacing a piston 26 in a boring 14, thereby moving a viscous fluid from a chamber 32 into a chamber 34 via a nozzle 36. According to the size of the nozzle 36 which can be varied using a pointed screw 38, the time necessary for the piston 26 to free an arm 74 connected to the valve R can be varied. In this way the speed of operation of the valve can be controlled. Such a device could be used to advantage in aeronautic and space domains.

Patent FR-2635872-A1 (FR)
Title: Apparatus for monitoring the condition of an object
IPC: G01N27/04
Filed: 1988-08-30
Abstract: The present invention relates to an apparatus for monitoring a physical value representing the condition of an object which is subject to being held under a specific condition such as the degree of moisture of the soil in a flower pot. The monitoring apparatus according to the present invention measures the electrical resistivity of the soil which depends on the degree of moisture in the latter. In order to eliminate parasitic potentials or currents which are present in the moist soil, the resistivity of the soil is measured by a pulsed current, so that an emitter probe S1 creates an electric field in the soil contained in the flower pot, which electric field follows the form of a pulsed measurement current D and is detected by a second receiver probe S2, the waves S1 and S2 being without resistive coupling. In this manner, possible parasitic voltages and currents in the soil are eliminated from the response signal received by the probe S2. The monitoring apparatus according to the present invention may be contained in a box which is buried in the soil, or it may be incorporated in flower pots.
