Title: Device allowing the location of a person who has fallen overboard from a boat
IPC: B63C9/20
Filed: 1984-06-26
Abstract: Device facilitating the location of a person who has fallen overboard. The invention relates to a device for helping to locate a person who has fallen overboard in order to rescue him quickly. This device is in the form of a container fixed to the rear of a boat. This container contains a balloon of a fluorescent colour which is previously inflated with a gas having a density less than air (helium), a floating counterweight and a nylon cord connecting the balloon to the counterweight. In the case of someone falling overboard, this container will be opened manually or automatically and will release its contents.

Patent FR-2588666-A1 (FR)
Inventor: HENRY GEORGES
IPC: G01R15/06
Filed: 1985-10-14
Abstract: The low voltage capacitor of a capacitive divider of a metalclad substation is located in a sealed compartment separated from the substation enclosure. In normal operation, the compartment is in direct communication with the enclosure via a communication orifice. The compartment can be isolated from the enclosure by closing the communication orifice valve to drain this compartment and thus have access to the low voltage capacitor or to other components of the capacitive divider housed in this compartment. Any pressure or temperature difference between the compartment and the enclosure, liable to affect the measurement, is thus avoided, while authorizing access to the low voltage capacitor without having to drain the installation.
