Patent DE-2634830-A1 (DE)
Title: Pressure die casting machine - with non-return valve removed from intensifier piston to external pressure line
Inventor: GEIER ROLAND
IPC: B22D17/32
Filed: 1976-08-03
Abstract: The non-return valve is arranged outside of the intensifier piston in an external feed line of the hydraulic fluid. This feed line terminates at the free end into the space of the work cylinder on the piston side. To determine exactly when the intensifier piston leaves its position of rest, a spring-loaded feeler cooperates with a limit switch. This eliminates the weakening of the intensifier piston by any built-in non-return valve and the risk of cracks in the piston. The non-return valve now becomes more accessible for inspection.

Title: Electronic circuit delivering information - sends signals back to energy supply unit by keying element at energy input (DK 17.4.78)
Inventor: BLICHFELDT MOGENS ERHARDT DIPL
IPC: G08C19/16
Filed: 1977-08-19
Abstract: The circuit is supplied by an inductive and/or capacitive coupling circuit picking up electromagnetic radiation. Signals are delivered by the electronic circuit back through the same coupling circuit to the energy supply unit. This is down by brief keying of a keying element in series or in parallel with a rectifier at the coupling element output. This rectifier can be the one which supplies the energy from the coupling to the electronic circuit. A capacitor or another storage component is in parallel with the energy input. Its storage capacity is sufficient to supply the electronic circuit with energy during the keying periods without the voltage falling below a specified limit. It is recharged by the coupling circuit during intervals between keying periods. The energy supply unit has an electronic element scanning variations of energy supply due to the above keying.
