Title: Aquarium filter and installation - has pump drawing water from bottom of filter compartment to aquarium base
IPC: A01K63/04
Filed: 1974-05-17
Abstract: The aquarium (1) has a vertical bulkhead (3) which shuts off a sealed compartment (4) separated by a bulkhead into two sub-compartments, one containing an electric pump. A bulkhead forms the fourth wall of the second sub-compartment and of a compartment having at its lower part a grille supporting a filter cloth and filtering elements covered by an upper grille. Wall (3) has perforations connecting the aquarium and filter. The pump sucks water contained in the second sub-compartment and delivers it through a pipe (20) to the bottom of the aquarium. This tends to empty the sub-compartment and creates a current through the perforations, down through the filter and the second sub-compartment. By this system the water is efficiently filtered and the level in the aquarium remains constant.

Patent FR-2278963-A1 (FR)
Title: Pressure system for flowing media - has store vessel supplied by valve device containing valve component which is displaced when system is in use
Inventor: EYLES LEONARD WILLIAM
IPC: F15B1/027
Filed: 1975-07-08
Abstract: Pressure system for flexing media, where the stove is supplied via a valve device, contains a valve component which is displaced when the system is in use. The displacement results by means of the input pressure which acts against an opposed force towards a position in which it cuts off the path for a discharge flow from the stove to a chamber at low pressure. The opposed force, when the input pressure is raised, so acts that a movement of the valve component is caused from the above-position to free the path for the discharge flow and so allow a discharge at the stove. Specifically the opposed force is produced by the stove pressure.
