Title: Dilution appts. for concentrates and liq. foodstuffs - using potable water under press for mixing and homogenisation
IPC: B01F5/04
Filed: 1973-08-01
Abstract: Dilution appts. for concentrates, syrups and other liq. foodstuffs comprises a tap, fixed by a screw to a supporting plate. This is interposed between a prodn. source, or water main under press., and a dilution body. A tube, fitted with an anti-siphoning valve, dips into a reservoir of the concentrate at a lower level. In use, the plunger of the tap is turned by a handle to admit water to the dilution body where it creates a redn. in press.; this draws the concentrate from the reservoir. After passing through an adjustable needle valve the concentrate mixes with the water and flows out through the wide tube into a storage or distributing recipient. Appts. is extremely simple and robust; it neets no power supply. The section of the concentrate resulting from the circulation of the potable water under press. produces no appreciable noise, which might limit its use.

Title: Movable cover for liq container - has sealing ring inflated by liq drawn off with pump
IPC: B65D88/48
Filed: 1974-09-18
Abstract: The liquid container (2) has a cover (3) movable within it and sealed by an inflatable sealing ring (4) round its rim. The liquid in the container is used to pressurise the seal. Liquid is drawn from the container by an electric pump (9) and passed through a three-way valve (7) to a tube (5), which is at least partly transparent. Air in the tube and seal is thus compressed.

Title: Filter system for coffee percolator - uses centrifugal forces to move coffee grains into position lining walls of rotary perforated vessel
Inventor: VERDUN PIERRE
IPC: A47J31/22
Filed: 1976-01-19
Abstract: The coffee percolator uses a centrifugal system to move the powdered coffee into the "filter" position. Once the infusion is completed the centrifugal action ceases and the used filter powder may fall under gravity into a waste collector. The percolator has a shallow hollow vertical infusion chamber with perforated cylindrical walls, and which can be rotated about its vertical axis of revolution. The size of the perforations is such that the grains of coffee are retained within the cylinder. Coffee is produced by first introducing fresh coffee powder into the cylinder. The cylinder is then rotated centrifugal forces cause the powder to form a layer on the inside faces on the cylinder. Hot water is then introduced into the cylinder, and passes through the powder and perforations to emerge as liquid coffee.
