Title: Multistage press ejector - impacted by striker pin cam-guided toggle lever reciprocating with press ram slide
Inventor: RICHNER HANS
IPC: B21J13/14
Filed: 1975-02-26
Abstract: The ejector of an automatic horizontal multistage press is actuated by a guide arm which reciprocates together with the press slide carrying the press ram and slides along a base plate. The ejector pin in the die and its ejector rod end in a flange which can be hit by an impact striker. This striker is mounted on the end of an L-shaped toggle lever which is pivoted to the end of the guide arm; the other end of the toggle lever has a roller which rolls along a cam curve. This requires no separate drive for the ejector. The ejector movement is now directly linked to the press ram movement. Short pressed pieces can be held on the press ram side by spring-loaded retainer pins.

Title: Object safety monitoring circuit - has conductor loop around object with shift of object tripping alarm circuit
Inventor: RODE JOHANNES ING GRAD
IPC: G08B13/26
Filed: 1976-07-08
Abstract: The warning system monitoring the safety of objects responds when the position of the guarded object is changed, and this causes a shift in the frequency and/or amplitude of the safety monitoring circuit for turning on the warning signal. The system can be used in guarding displays when the public has a free access for inspecting a given object while shift of the object is detected for triggering the alarm. The triggering is ensured by a conductor loop around the guarded object set remotely in relation to the discriminator unit. The inductivity of the loop is matched to the oscillator by transformer while the output of the oscillator is handled by rectifier and its frequency changes are detected by discriminator. The resulting signals are transmitted to the summing amplifier which feeds the differentiator of alarm relay.
