Title: Motor driven by tensioned belt - has handle which displaces levers to tension belt which exerts net positive torque on rotatable discs
Inventor: SPEER ANTON DIPL ING
IPC: F03G1/00
Filed: 1978-02-16
Abstract: The motor consists of a hollow shaft (1) on which two drum shaped discs (7) are mounted. The drive arrangement incorporates a handle, which when rotated, drives a flexible shaft (15). When the flexible shaft is rotated the pivot of two levers (11) are pulled together, so that a cable or belt (13) is extended and placed under tension. The force exerted by the belt is transmitted by a second belt or cable (14) so that positive and negative torques are exerted on the drum shaped discs. As the positive torque exceeds the negative torque, the whole assembly is rotated.

Title: Servo valve hydrodynamic controller - regulates medium flow direction by slots and drillings in control plunger
Inventor: KUCHARZYK REINHARD ING GRAD
IPC: F15B13/043
Filed: 1979-09-26
Abstract: The hydrodynamic controller regulates the flow to the control plunger of an electro-hydraulic servo-valve with barometric and/or mechanical control of the return flow. The flow direction for the medium under pressure to and from an annular chamber (9), which is open on one side, is regulated by slots and/or drillings (7) in the control plunger (8) so that the dynamic flow forces, acting axially on the plunger in the closing direction, increasingly oppose the setting force with rising pressure difference and flow rate. Thus the plunger is slid from the desired position in the closing direction, as necessary for an even flow of medium under pressure independent of load, the value of this flow being determined by the electric signal acting on the control magnets (a,b). The slots and drillings are so inclined to the long plunger axis, as to maintain the preset rated deviations as far as possible.
