Title: Mortice lock suited for metal doors - has lock bar with built in safety catch to avoid levering of lock bar
Inventor: ISKEN KLAUS
IPC: E05B63/12

Title: Magneto ignition system for single cylinder engines - has two way rectifier between impulse transmitter and compensator
Inventor: HAUBNER GEORG
IPC: F02P1/08

Patent DE-2344825-A1 (DE)
Title: Treating cast concrete panels to form ribbed surface - using rapidly rotating discs moved over surface, to raise aggregate
Inventor: PATON WILLIAM DONALD
IPC: B28B11/08
Filed: 1973-09-05
Abstract: Cast concrete panels are surface-treated to produce a ribbed surface with exposed aggregate on the ribs, which are formed in the free surface of the wet concrete. Aggregate is raised to the surface of the ribs by advancing parallel discs revolving on a shaft and penetrating the wet concrete at the lower periphery, to press grooves in, between neighbouring ribs, with compressed upper surfaces. The discs revolve so fast that the aggregate is transported upward between the discs, which are moved relative to the concrete with their lower ends, due to their rotation and running forward over the surface of the concrete in the same direction. A furrow is milled into the wet concrete in front of the discs along the surface of the concrete. Hand processing is eliminated.
Patent DE-2345505-A1 (DE)
Title: Vehicle disc brake pad - with ferromagnetic protrusions on the lining rear sticking to corresponding magnets on the lining holder
Inventor: ROCHOLL HANS
IPC: F16D69/04
Filed: 1973-09-08
Abstract: The usual mode of fitting for disc brake pads is that of a dovetail arrangement, enclosed on three sides and open on the fourth side in order to permit the introduction of the pad into the holder. The dovetail has to be shaped to permit a certain movement of the pad along the dovetail, as well as in perpendicular direction during braking action. This arrangement entails a certain risk of dropping out of the pad from the holder when the play between holder and dovetail guidance is excessive and no braking action takes place. The present design ensures a positive holding of the pad onto the holder in all circumstances.
