Title: Domestic water tap with push button control - permanent magnet is pushed down to open orifice and second push raises magnet
IPC: F16K7/17
Filed: 1974-09-20
Abstract: Depressing the button (14) lowers the magnet (29) whose radial projections (30) slide in grooves (26) in the head (11) until free (31).

Title: Non-return pipeline valve - has space between conical valve member valve seat
IPC: F16K15/14
Filed: 1975-04-18
Abstract: The valve consists of a conical, basket type valve seat (6) with a flange (2). Orifices (4) are formed by ribs (5), and the point of the cone has a hole (3).
