Title: Medium frequency static converter - has two overload-protection diodes each shunting one transistor switch and transformer primary
Inventor: SIEPMANN RICHARD
IPC: H02M3/335
Filed: 1974-09-20
Abstract: The medium-frequency static converter has diodes (D2, D3) to conduct away extra current. The diodes are coupled in parallel with the primary winding of the transformer (U1). Two transistor switches (T1, T2) are connected to the ends of the transformer primary and are both in series with it.

Title: Rotating panel for bank counter - uses sets of double skinned leaves forming bulletproof shield in closed position
Inventor: REICHLIN MAX
IPC: E06B9/02
Filed: 1975-10-08
Abstract: The panel consists of leaves with journalled either in the centre line of the leaf or at one of the longitudinal edges. The leaves are constructed from two sheet metal strips (1, 2) with a lens shaped cross section rotating around point (a). The two edges (1a) of the leaf overlap with similar edges of the adjacent leaves. The material of the sheet metal strips resists bullet penetration using the decelerating property of the air gap. Instead of positioning the rotary axis in the centreline of the sheet metal strip, it can be at one edge of the leaf, in which case the double skinned design is achieved by turning over the sheet by 180 degrees with one rounded edge (21a) and the two sheet metal edges meeting at the other edge (21b).
