Title: Viscous fluid damper for rotor - has magnetic ball loosely fitted in sealed curved fluid tube between magnet poles
Inventor: SCHULTZ PETER DR ING
IPC: F16F15/03
Filed: 1975-09-09
Abstract: The damper for the casing of a rotor (5) rotating about an axis (3) is completely fluid-tight and uses a magnetic obstruction positioned in a viscous fluid in an arcuate tube, instead of a mechanical rod and piston linkage which requires careful sealing which in turn produces awkward friction effect. The radius of curvature of the tube (7) corresponds to the distance from the rotor axis (3). The obstruction 79) is a sphere of magnetic material (soft iron) which has a rest position between the poles of a permanent magnet (11). The tube moves past the ball and magnet with its movement damped by the viscous fluid passing through the narrow clearance between the ball and the circular tube interior.

Title: Vapour condensation mechanical energy system - produces energy admitting vapour in rotor chambers to displace water to create reaction torque
Inventor: GULAIF JOSEF
IPC: F03B17/00
Filed: 1976-01-14
Abstract: The mechanism produces mechanical energy as a result of the condensation of water vapour. It comprises a rotor with chambers separate by blades and on one side closed by a fixed, curved partition. The rotor is arranged in a partly water-filled vessel and water vapour is admitted into the chambers via a nozzle or the hollow rotor shaft and parts. Water present in the chambers is displaced by vapour, causing the rotor to rotate. The energising vapour and water enters the chambers of a second, higher rotor. The condensator process is assisted by a cooling unit circulating a coolant through a spiral in the vessel and by injecting water.

Title: Relay or protective circuit breaker trip - has soft magnetic shanks with ferrite windows for control current flow
Inventor: LAUERER FRIEDRICH DIPL ING
IPC: H01H71/32
Filed: 1976-06-14
Abstract: The magnetic device forms a relay or a tripping device of a protective circuit breaker. The soft magnetic shanks, leading from permanent or electromagnets to the armature are of a ferritic material and contain windows, through which flows the control current which provides magnetic saturation in the window regions. Thus the penetrating magnetic flux is blocked and the armature, drops off. The application of ferritic material avoids the relatively high excitation required for relays etc. using laminated structures since ferritic materials have very low losses. Thus a lower excitation power is required for saturation.

Title: TTL light meter incorporating diffusing reflector - can respond differently to various parts of enlarged image area
Inventor: FUKUHARA TORU
IPC: G03B7/099
Filed: 1976-08-31
Abstract: In the simplext version of the light meter part of the light from the lens passes through a lightly-silvered area of the camera's mirror on to diffusing reflector (of convexities and concavities, uniformly distributed) and thence to the photocell. The effect of the diffusor is to gather light from a greater picture area than a polished mirror. In one version, the strength of the diffusor (38) - a liquid-crystal layer set between transparent electrodes (37a) - can be varied electrically. Thus the photocell (6) may receive light from a polished mirror - effectively the picture area (AC) - or from a diffusing reflector - picture are (BD). By making the liquid-crystal layer (38) of different thicknesses in different parts, the degree of response to light coming from the various outer areas of the picture can be regulated.
