Title: Rotary piston IC engine - has three sided piston with double rotary motion inside two sided cylinder avoiding gear drive
Inventor: BRINNER HANS-WERNER DIPL KFM
IPC: F01C1/22
Filed: 1977-03-17
Abstract: A rotary internal combustion engine has a cylinder with a cross section formed by two curved walls (26) between two end plates. The piston (27) has a cross section formed by three curves with sealing strips (33) at the corners between these curves. The piston has an internal recess (37) in which a connecting rod (35) presses against an internal face (36) and transmits the motion it receives to an output shaft (22). The piston revolves simultaneously about two points which are the centres of the curved sides of the cylinder. The radii of the curved cylinder sides are multiples of the distance between the two points. This gives the necessary complex motion of the piston without gears or eccentrics which greatly simplifies construction.

Title: Screen printing of heated glass panes - using stencils with layers running across meshes for boundaries without sawteeth
Inventor: ESSENBURGER GERHARD DIPL ING
IPC: H05B3/84
Filed: 1977-04-07
Abstract: Electrically heated panes of glass for road and rail vehicles are produced by narrow resistance strips with a compsn. contg. metallic silver which are applied by screen printing and fired. The screen printing stencil which is used has layers which run across the fabric meshes to form a smooth strip boundary. After firing, a preliminary copper plating produces resistance 15% above the final value. The resistances are now measured and the panes are divided into resistance groups. The final plating stage is applied under the same conditions for all panes in a group in automatic plant. This results in a smaller scatter band for the resistances and requires less labour and equipment. The amount of scrap is reduced and the stencils have a longer life. The whole operation can be automated more readily.
