Title: Elastic coupling for electric motor shaft - with spring loaded epicyclic gears which tension control spring by reaction force
Inventor: STIBBE WERNER
IPC: F16D3/50
Filed: 1974-06-12
Abstract: The shaft (1) from the motor drives the output shaft (2), which is directly connected to the coupling housing (9) via two pinions (4, 5) driven by a gearing on the drive shaft. The two pinions drive outer gearing sleeves (6, 7) connected by a strong spiral spring (8). The gear ratios between the two pinions and their sleeves differs by one tooth so that when the coupling is driven a reaction force tensions the spring and drives the housing, and hence the output shaft. When the housing is driven the effective tooth difference becomes zero. The coupling enables the input and output shafts to rotate relative to each other over several revolutions, thus providing a smooth power drive.

Title: Two chamber syringe has plunger with one way valve - opened by pull of plunger rod on plunger plug
Inventor: HUETTERMANN WILLI
IPC: A61M5/315
Filed: 1974-10-23
Abstract: A two-chamber injection syringe has a fixed end plug and a movable plunger plug operated by a rod passing through the fixed plug. The end of the rod penetrates into a partially blind hole in the plunger plug and has a coaxial projecting nose at its tip which continues into and normally seals a small dia. bore which continues through from the base of the blind hole to the other side of the plunger plug. The end region of the rod is fixed inside the plunger plug by backward pointing barbs and has, between these barbs, long longitudinal grooves in its surface. Thus, in the normal posn., before the liqs. in the two chamers are to be mixed the nose of the rod seals the passage through the plunger plug and the grooves are covered and therefore inoperative, whereas when the rod is pulled back the nose retracts a little from the passage fand the grooves come out of the rear face of the plug, so that communication is established between the two chambers. The barbs form a firm engagement and do not strip matl. from the inside of the plug. No special action is required to open the valve in the plunger plug.
